Hello, and thank you for joining us to hear about BHP's results for the December 2021 half year. I'm joined today by David Lamont. I am pleased to be able to announce today another strong set of results. We safely delivered record first half earnings and shareholder returns, and we continued to execute on our strategy. We had solid underlying operational performance in the majority of our assets. We maintained cost discipline amid escalating inflationary pressures. We made good progress on our portfolio-related actions in coal, petroleum, and potash. We unified our corporate structure, further simplifying the business and creating a stronger platform for growth. We're doing what we said we would do. We're creating significant long-term value for shareholders, and we're benefiting society through sustainably meeting the world's growing need for resources. This half year has produced a number of highlights.
Most importantly, we achieved our third consecutive year without a fatality. Our high potential injury frequency, one of our key safety indicators, decreased by a further 10% during the half. This measure has improved by over a third over the past three years. Continuing with safety, I deeply regret that in spite of all of our efforts of recent years, people continue to experience instances of sexual harassment and assault in our workplaces and accommodation villages. This conduct is completely unacceptable. I am absolutely committed to eliminating it from BHP, and we continue to take strong action. On the production front, our Western Australia Iron Ore business ran at very close to record levels, and Escondida saw record material mined during the half.
We faced a number of continuing external challenges across the business, and these include ongoing COVID measures, constraints on labor mobility and availability, supply chain issues, twice as much rainfall at our Queensland coal operations as last year, and of course, inflation in the cost of key inputs. However, we retained a sharp focus and solid control over costs right across the business. We're also making good progress on reshaping our portfolio in line with our stated intent. We took the decision to proceed with the Jansen Stage 1 potash project. We announced the merger of our petroleum business with Woodside, and we further consolidated our coal portfolio into the highest quality coals for steel making. We continued to develop more internal options for growth in copper and nickel, and secured a number of further options through exploration and early-stage entry.
Having completed the Spence Growth Option on time and on budget, production ramped up during the half, albeit recoveries are trending lower than expected and some plant modifications are being planned in order to achieve full intended production levels. This operational performance, combined with high prices for a number of our products, is reflected in our strong financial results. Underlying earnings per share were up 77%, and return on capital employed increased to 43%. Strong cash flow generation means our balance sheet remains in excellent shape, and today, we announce an interim dividend of $1.50 per share, representing a strong flow-through of our underlying financial performance for the benefit of shareholders. Our success is measured not only by how well we create value and returns for shareholders, but also by the way in which we benefit society and our other stakeholders.
Shareholder value creation is not sustainable without a focus on social value creation. We're delivering on our climate commitments. During the half, our climate transition action plan via our say on climate vote, received strong support from our shareholders. We're on track to meet our operational emissions reduction target. In fact, compared with the same period last year, we've reduced absolute emissions by 16% as renewable power contracts at a number of our operations commenced. We're continuing to build on our partnerships along our value chain to support pursuit of our net zero by 2050 Scope 3 goal. We're also building a more capable workforce that better reflects the communities in which we operate and where people feel safe and are able to contribute to their full capacity. More inclusive and diverse teams deliver safer, better business performance, as we've demonstrated over recent years.
We're making good progress towards our aspirational goal of a gender-balanced workforce by 2025. Just shy of half of our external hires over the past six months were female, and women now comprise 30.6% of the workforce. The executive leadership team at BHP is already fully gender balanced. We've also raised the proportion of our employees, including those in leadership positions from First Nations backgrounds in Australia, Chile, and at our Jansen Potash project in Canada. We look forward to updating you on our approach to social value in more detail in the coming months. I'd like to now hand over to David to take you through our results in more detail. David, over to you.
Thanks, Mike. Despite the challenging conditions, the quality of our assets and people, together with the robust demand for our commodities, enabled us to deliver a solid set of financial results in the first half. Our resilient operational performance and strong cost control, combined with higher prices, drove underlying EBITDA to $18.5 billion, up 33% at a very healthy margin of 64%. This excludes petroleum, which is treated as a discontinued operation as we progress the merger with Woodside. The adjusted effective tax rate was just over 30%, slightly below our guidance range due to the reclassification of petroleum. This increases to just over 37% with the inclusion of royalties. Underlying attributable profit of $9.7 billion increased 57%. Including petroleum, this increases to $10.7 billion.
We recorded a net exceptional charge of $1.2 billion after tax, comprising $800 million for the Samarco dam failure, largely due to updated cost estimates for Renova's programs, and a $400 million impairment of U.S. deferred tax assets no longer expected to be recovered. EBITDA waterfall shows the significant benefit of the higher prices for our core commodities, with metallurgical and thermal coal prices both close to triple that of the December 2020 half. Copper and nickel each up 30%, and iron ore 9% higher. The favorable impacts of the weakening Australian dollar and Chilean peso against the US dollar were offset by inflationary and commodity input cost pressures, in particular for diesel and acid. However, we maintained a tight lid on controllable cash costs.
Contributing to the increase was the South Flank ramp up and high demurrage costs due to quarantine requirements in Western Australia, as well as around $150 million in COVID-related costs, which were treated as exceptional in the prior years. This was partially offset by lower operational activity at Olympic Dam due to the major smelter rebuild. Our strong operating performance at Western Australia Iron Ore and higher concentrate sales at Spence were more than offset by lower volumes at Escondida due to a lower feed grade, at Olympic Dam due to the maintenance program, and the impacts of significant wet weather and labor constraints at Queensland Coal. Across the portfolio, our underlying operations performed well despite these headwinds. We continued to apply BHP's operating system, BOSS, principles to unlock even greater performance.
For the first time since FY 2017, all of our major assets delivered EBITDA margins in excess of 50% in the half. Western Australia Iron Ore delivered record lump sales driven by the ramp-up of South Flank, contributing to strong price realization above the benchmark. Full-year unit costs are trending towards the lower end of the $1,750-$1,850 per ton guidance range at our $0.78 guidance FX rate. Of course, if the current Australian dollar rate continues, we'll do better. In copper, EBITDA increased 14% to $4.3 billion, driven by the higher realized prices. Escondida's unit costs are tracking in line with full-year guidance, and concentrate feed grade is expected to improve in the second half as we mine higher grade areas.
Despite Queensland Coal experiencing double the amount of rainfall versus last year, it achieved a $2.2 billion increase in EBITDA, with average realized prices almost 3x the prior period. The increase in unit cost guidance reflects the lower production guidance. Nickel West Sulfate Plant delivered first crystals, an essential ingredient for batteries used in electric vehicles. Ramp-up will continue throughout the remainder of the year. We now sell more than 90% of our nickel metal to the battery market, up from no sales only six years ago. This comes at a time of increasing demand, with average realized prices for nickel metal just under $20,000 per ton in the first half. For potash, our projects continue to track well.
The shafts are now 98% complete, and the Jansen Stage 1 project is underway with approximately $1.2 billion in contracts out of the $5.7 billion investment already awarded. While treated as a discontinued operation, the petroleum business also continues to perform well. During the half, production increased by 5% and cost control remained strong, and we expect production and unit costs to be consistent with original guidance until merger completion. Our major projects proceeded on time and on budget. We continue to perform well, capitalizing on the strong demand for the commodities we produce with guidance largely unchanged. While we are well-positioned, we're acutely aware that the lag effects of inflation, weather, and labor availability are challenges we will continue to contend with in the second half and into FY 2023. Turning now to capital.
Our commitment to our capital allocation framework, or CAF, is stronger than ever. It has served us well since it was put in place back in 2016. Our first priority remains to invest in maintenance capital to sustain and improve asset integrity in order to deliver stable and reliable performance. Over the past six months, this amounts to $1.1 billion. Our balance sheet is in good shape with $6 billion of net debt, compared to $26 billion at the end of FY 2016. We have consistently exceeded our minimum 50% dividend payout ratio we implemented with the policy. Beyond this, we continue to reinvest back into our business, spending $1.8 billion this half, excluding maintenance and petroleum. This ongoing discipline has supported an increase in return on capital employed from continuing operations to approximately 43%.
In FY 2022, we expect to spend a total of $6.5 billion on capital and exploration expenditure, excluding petroleum, marginally below prior guidance due to favorable FX movements. While spend may be higher in future years, both due to Jansen and as attractive opportunities to reinvest in our business present themselves, we remain disciplined. Today, we announced a dividend of $7.6 billion, taking our total returns to shareholders to over $22 billion over the past 18 months. In light of our strategic announcements in August last year, we have revised our net debt target range from $12 billion-$17 billion to between $5 billion and $15 billion. This revised target range will enable BHP to maintain a strong balance sheet throughout the cycle, including during periods of portfolio change, liabilities associated with the Samarco dam failure, and external uncertainties.
It also provides flexibility to allocate capital towards shareholder returns and future investment opportunities, be they internal or external. Before I wrap up, I wanted to take this opportunity to run through how we apply the capital allocation framework to investment decisions. While the CAF was a major step forward, as we do around the business, we continue to learn from the past and refine our processes. We have a broad range of investment opportunities in front of us, and under the framework, all options, small and large, internal and external, compete for capital, all go through the same process. We consider a range of metrics, including net present value, internal rates of return, and payback periods, and incorporate risk, both upside and downside, to come to a decision. There is no single hurdle rate we apply to investment decisions.
We factor in how individual opportunities impact both the portfolio, our decarbonization metrics, social value commitments, and ultimately shareholder value and returns. Importantly, we consider all metrics in ranges rather than point estimates or mid-cases. As a demonstration of both the power of the CAF and our discipline in applying it, during the half, we made the decision not to increase or extend our offer to acquire Noront. While a promising nickel resource, we ultimately did not see adequate long-term value for shareholders at the final offer price and believe this capital can be better utilized elsewhere. On that note, I will close by saying that we have reported a strong set of financial results for the half. We are maintaining tight cost control over cash costs despite headwinds.
The portfolio is performing well in a high-price environment, and we remain committed to our capital allocation framework to ensure we continue to deliver long-term shareholder value. Thank you. Back to you, Mike.
Thanks, David. I'd like to talk now about what lies ahead. We've been clear about our commitment to social value and to delivering shareholder value through operational excellence and growth in future-facing commodities. We've made great progress. In spite of a near-term operating environment that remains complex and challenging with the pandemic, inflation, disrupted trade patterns, and dynamic stakeholder expectations, our strategy, high-quality assets, strong balance sheet, and capabilities position BHP exceptionally well for circumstances like these. This is reflected in our continued strong results and the progress in our portfolio over the past six months. In terms of the near-term outlook for commodity demand, while growth slowed in China more than we anticipated in the second half of calendar year 2021, we see the headwinds easing over the course of 2022. Real estate policies are easing, including in the critical area of developer financing.
The beginning of China's new five-year plan will bring greater infrastructure spending. Exports are likely to remain a support for growth, and direct constraints on heavy industry are expected to ease. For the fourth year in a row, our mid-case is for Chinese steel making to exceed 1 billion tons in 2022, supporting demand and pricing for our iron ore. While we're seeing stark inflationary pressures globally, with major value chains in food, construction, materials, autos, energy, and logistics all moving higher, it's important to differentiate between the drivers of this, supply chain bottlenecks, which as David indicated, we expect to contend with for another year or two, versus inflation that is demand led, which we expect to be more enduring. This latter driver is positive for commodities demand and pricing. The longer-term fundamentals for the commodities BHP produces remain very positive.
The resource sector is essential to the meeting of global aspirations for sustainable long-term growth. Demand for energy, metals, and fertilizers will be underpinned by population growth, urbanization, decarbonization, and rising living standards for decades to come. BHP's portfolio, capabilities, and distinctive approach to operational excellence and the creation of social value place us in an advantageous position when it comes to being able to meet this demand. Our strategy is aligned to these global aspirations. It provides clarity on the commodities and assets we want and the capabilities we need to excel at in order to maximize value and returns from these assets.
We've made significant progress already by increasing our exposure to future-facing commodities through sanctioning the Jansen Potash project and adding exploration and early-stage options, by progressing our divestments of BMC and Cerrejón, as well as the merger of our petroleum business with Woodside, and by simplifying our corporate structure to make us more efficient and agile. Of course, plenty remains to be done. We'll continue to reposition our portfolio for greater leverage towards the key mega trends playing out around us, and we'll continue to improve operational performance to deliver our products even more reliably and sustainably. BHP's fierce commitment to sustainability and social value is evident in our approach to areas such as health and safety, community engagement, climate, water, and cultural heritage. We also scored our best ever results in our most recent global customer satisfaction surveys, and these were particularly strong in China and India.
Our customer relationships have never been better. This includes deeper collaboration on sustainability initiatives. For example, we recently partnered with both Southwire and Tesla on blockchain pilots to trace greenhouse gas emissions associated with our copper and nickel products, contributing to collaborative efforts to reduce emissions across value chains. We've also progressed our partnerships with steel makers, representing around 12% of reported global steel production to help advance the green transition of the steel industry. This includes a new collaboration with China Baowu and three top Chinese universities on the development of low-carbon steelmaking technologies and their future application at plant scale. BHP is also a proud contributor to the regions where we operate. We've continued to support COVID-19 efforts, including vaccine awareness and accessibility for local and indigenous communities.
We're supporting small, local, and indigenous businesses through reduced payment terms and the $1.2 billion spent with over 4,000 local suppliers across the globe over the past six months. We have sector-leading assets, and we aim to operate them exceptionally well. These assets generate strong margins through the cycle and create a baseline of stable cash flows that our shareholders consistently benefit from. In fact, in all bar one of the last 15 years, we've delivered net operating cash flows of more than $15 billion. In iron ore, our assets constitute the best combination of scale, quality, and cost competitiveness in the Pilbara, and we have room to grow should market conditions warrant. Our reliable delivery is valued by customers, and our higher quality iron ores will remain attractive as steel makers strive to reduce emissions through improved productivity.
The need to reduce steelmaking emissions will also drive a growing market preference for higher quality metallurgical coals. We produce some of the world's best quality coals for steelmaking, and over the past 12 months, we've seen increasing premiums for these. In copper, we have some of the most sustainable operations within one of the largest resource bases globally. This provides significant optionality. We are well-positioned to take advantage of growing demand for copper required for urbanization and electrification. At Nickel West, we're studying ways to unlock growth from what is the world's second-largest nickel sulfide resource. Of course, with the approval of Jansen Stage 1, we've entered into another commodity with attractive fundamentals in the world's best potash basin. This opens a new future growth front for the company with significant expansion potential, which is expected to support up to a century of production.
As David mentioned, our petroleum business continues to perform well operationally, and we've enjoyed healthy oil and gas markets and strong prices during the half, all to the benefit of our shareholders. The merger with Woodside remains on track to be completed in the June 2022 quarter. It will combine two great businesses that will be even better together, will unlock synergies, and will create a global top ten independent energy company. The combined business will have a high-margin oil portfolio, long-life LNG assets, significant growth optionality, and the financial resilience to help supply the energy needed for global growth and development over the energy transition. Importantly, it will offer value and choice for BHP shareholders. As I flagged on previous occasions, we are creating and capturing more opportunities to deliver value growth.
Our first priority, of course, is protecting and growing value through delivering safe, reliable operational performance with a strong focus on continuous improvement every day. In terms of high returning production growth, our current portfolio of large, long-life resources offers plenty of opportunity for organic growth through further debottlenecking and by larger brownfield expansions, including bringing innovation to bear in ways that enable us to unlock more of our resources more quickly and at attractive returns. At Escondida, where we expect production to average 1.2 million tons per year over the next five years, we are assessing brownfield options to unlock more of this world-class resource. This will enable us to mitigate the effects of future grade decline. At Spence, we are currently bedding down the Spence growth project, but we'll look to future optionality here as well.
Over the next five years, across all our copper assets, we expect production of around 300,000 tons per annum, more than 2021 levels. At Nickel West, as well as looking at opportunities to grow production, we're increasing the value of our product. We've now produced first crystals from our nickel sulfate plant and will ramp up to around 20,000 nickel equivalent tons per year, supplying the electric vehicle battery market. At Western Australia Iron Ore, we've increased our export license to 330 million tons per year out of Port Hedland, providing headroom to pursue low-cost initiatives across our mines, railways, and port facilities. We're being more agile and commercial and building our capability to add to our options through exploration, innovation, early-stage entry, or mergers and acquisitions. Technology and innovation are areas of particular focus.
As well as working internally, we're collaborating externally to solve big challenges. We're looking at how to improve productivity and deliver better value from installed capacity at our assets, including with autonomous haulage and primary sulfide leaching. We're also investing in emerging technologies to give us more competitive edge and to drive sustainable growth across our current operations, our resource base, and our value chain. We've cast the net wide. For example, working with startups and academia to investigate a number of innovative iron ore beneficiation concepts. With Jetti Resources, who are developing a novel catalyst to more economically recover copper from low-grade chalcopyrite, and with KoBold Metals, who are looking to apply machine learning to revolutionize the way we discover new deposits. We're also adding to our suite of early-stage entry options.
Last year, we invested in Kabanga Nickel in Tanzania, gaining access to what might be the world's largest development-ready nickel sulfide deposit. This adds to our existing suite of early-stage entry options in Ecuador, Australia, Canada, and Mexico. As always, one of the most important pathways to volume and value growth is investing in our people. Year- on- year, we continue to embed the BHP Operating System, which we put in place in 2017. BOSS is our way of leading and working that is delivering results. By increasing the capability of our workforce in this way, we are improving our decision-making, our efficiency, and our productivity. BHP is well-positioned to create and grow value. We've demonstrated our ability to execute well through all of the challenges the world and industry have faced over the past six months and continue to face.
In addition to maintaining safe, reliable operations, we've progressed a number of strategic decisions and actions in parallel. We're improving our growth outlook and our leverage to commodities that stand to be positively impacted by the big trends underway, not least of which is action on climate and decarbonization. After the divestments we currently have underway, we'll be left with a portfolio that is all or almost all comprised of commodities with decarbonization upside: copper, nickel, potash, and higher quality iron ore and coals for steel making. We're delivering more reliable operational outcomes enabled by our efforts on workforce, the BHP Operating System, and technology. This powerful combination of operational excellence, a stronger portfolio, and social value will underpin continued attractive returns on long-term value growth. Thank you.

I would now like to hand the conference over to Tristan Lovegrove, BHP's Group Investor Relations Officer.
Thanks, operator. Hello, everyone, and thank you for joining us today. I'm joined today by Mike and David to answer your questions. With that, we are ready for the first question, operator. Operator, we're ready for the first question. Operator, are you there?
Yes. Tristan, it's Paul Young from Goldman Sachs. Am I open?
Yeah, we can hear you loud and clear, Paul. Off you go.
Okay, great. I didn't get a prompt. Hi, Mike. Hi, David. Thanks for the call. First question is for David on the net debt range. David, that $10 billion range is much wider. I presume that's due to the increased earnings volatility with our petroleum. The question is, are you prepared to go above the top end of the range in the event of a good opportunity comes along? The second question is for Mike around the portfolio, and it's actually on met coal, Mike. A fantastic half for met coal. It's gonna get even better this half where met coal prices are. You dropped your medium-term target on volumes a while back. How do you create value from met coal from here, Mike? Is it around increasing volumes with demand, or is it more around decarbonizing the truck fleet? Thanks.
Okay, David, you're on net debt.
Yeah. Thanks, Paul, for the question in relation to the net debt range. You're right, we've widened the range. Effectively, you know, the basis behind that was obviously looking at the petroleum impact and the fact that petroleum came out, and that's why we've now got the range of $5 billion-$15 billion. Importantly, as you did flag, we have significantly deleveraged the balance sheet. When we're paying out the sorts of dividends that we've just announced, you know, the $7.6 billion coming on the back of over the $10 billion at the full year, and that just meant that we were getting below the bottom end of that range. Yes, we widened the range to $5 billion-$15 billion, which, you know, recognizes the significant deleveraging that we've actually had.
Specifically, your question though is, would we be prepared to move above the top end of the range? There has been no change to that as a result of the change in guidance from the $12 billion-$17 billion to the $5 billion-$15 billion. We always said for the right acquisition, we would be prepared to move outside that range. Obviously that is dependent upon finding the right acquisition as part of that process, and we'll be very diligent as we have been in the past, around the application of the capital allocation framework to any opportunities on growth.
Paul, let me pick up on your question around met coal. Your question was around, you know, how do we go about creating value in met coal? Really it's a strategy that's similar to what we have in iron ore, which is, the way that we create value that is most enduring is through a sharp focus on productivity and improving the overall quality suite or the average quality of the product suite. Now, the way that we're going about that in met coal is through optimizing the portfolio. You've seen the successful divestment of the BMC assets, which leaves us with a portfolio that's more skewed towards the highest quality hard coking coals that we believe are going to be in greatest demand and have the greatest price premium.
In tandem with that, we need to be driving productivity further. Now, some of that will come through things like decarbonization of the truck fleet over time, but there's a lot more that we need to do there as well in terms of driving operational performance. Which is, you know, we've had some external drags on operational performance, like the doubling of rain over the course of the past year, COVID and so on. But once we're through that, and hopefully into a more stable period in terms of weather, then we'll see the true operational performance of that business. So that focus on reliable operations, driving productivity is the value lever that is most in our control.
In addition to that, depending on how markets play out, there is upside there on volume, but it's all very uncertain at this point in time because we've been locked out, or Australian coal has been locked out of a market that made up about 25%-30% of our sales before the, you know, before the ban was put in place. If that were to change a few years down the road, then the effective market we could access would grow and there may be more by way of volume upside, but not for now. Right now the focus is all on that kind of portfolio optimization and driving productivity.
Very good. Thank you for that.
Operator, our next question, please.
Your next question comes from Hayden Bairstow of Macquarie. Your line is open. Please go ahead.
Good morning, Mike and David. Just two questions from me. Firstly, just on is there any sort of guidance you can provide on capital management? Obviously, with that debt range being nice and wide now, there's plenty of flex there. Is there any likely plans to look at anything post the Woodside transaction or are we just gonna be waiting for the full year result in August before you'd potentially, you know, look at off market buybacks or whatever, some shifting in the capital management plans? Then the second one, Mike, just on the iron ore business, obviously, you know, the government's finally rebased Port Hedland at a more sensible capacity level. It sort of cleared the path for you guys. If you wanted to push beyond 300 million towards 330 million, you could.
Is there anything sort of in the works that may become part of the base case that you'd look at a, you know, more train loadout capacity to get that ultimate, you know, system capacity to that sort of level?
Okay. Well, thanks, Hayden. I'll take the one, David, on Port Hedland and iron ore, and then I'll pass to you for capital management. Hayden, you know, the strategy in iron ore remains exactly as it was. Which is continue to focus on reliable operations, eking out a little bit more production, keeping a lid on costs, and improving the overall product suite in terms of quality. You've seen us do that with South Flank, which is increase the proportion of lump in the mix, increase the average FE content. All of that's playing towards that strong focus on decarbonization in the steel industry and the draw that's going to exist for higher quality products. We're seeing the benefit of that now.
As you can see coming through the cost performance and the production performance, things are going pretty well there, operationally as well. Now, what the increase at Port Hedland does do for us is two things. One is it ensures that we don't get into this weird situation where we run up against, because of the strong underlying operational performance, we hit up against the 290 million tons per annum wall and then have to curtail things. This gives us a little bit of flex beyond that, and we may, you know, all things going well and current trends on performance continuing, we'll creep beyond that.
There are no plans in the works right now to go to the 330 million ton allocation that's been given. Of course, we have the ability if market circumstances were to warrant to grow further, but we don't have anything currently in train for that. David?
Hayden, on the capital management side of things, the first thing that I would say is that the board looks at the quantum of cash to be returned back to shareholders on a half-yearly basis, as we have done, obviously, through this period as we continue to look at how do we ensure that we return an appropriate amount back to shareholders. I would just flag that obviously with this announced dividend, it's $22 billion that we've returned to shareholders over the last 18 months. Significant amount of return in that context. Specifically, your question around would we look at doing anything on the capital management post the merger with Woodside? The short answer is no.
We obviously, though, continue to monitor things throughout the period within that debt range that we've come out with between the $5 billion and the $15 billion. As I said, the board looks at that on a six-monthly basis. Operator?
Thank you. Your next question comes from James Redfern of Bank of America. Please ask your question.
Hi, Mike and David. Thank you for the opportunity. Look, question in relation to the potash and nickel aspirations for BHP. BHP is becoming a more simple company post the merger, petroleum. Effectively three key commodities, iron ore, copper and met coal, which are a top three global producer in all three commodities. I'm wondering, is BHP happy to wait until 2027 before generating any earnings from potash? For nickel, BHP is kinda the ninth largest nickel producer globally. Does BHP also have aspirations to be a top three global nickel producer as well? I guess just wondering about your aspirations in potash and nickel in sort of near- to medium-term. Thank you.
So in the case of potash, you know, that is a long-term, quite significant growth opportunity for BHP. First focus is on executing the Jansen project well. You've seen, you know, the track record that we're building around good, solid project execution with both South Flank and SGO coming in on time and on budget. Then we'll look to the, you know, Jansen Stage 2, 3 and 4 beyond that. We do see that becoming a pretty significant part of the BHP business over time. We'll look to whether there is opportunity to accelerate the, you know, the build of Jansen Stage 1. But it's still gonna be around that timeframe, James.
You know, we're not feeling any need to do things materially quicker than that. As David said in response to an earlier question, we'll always be opportunistic and look at things as they arise. Now in terms of nickel, I think you know not all nickel is nickel isn't nickel. We're very focused on class one nickel and in particular you've seen us weighted about 90%, from memory David, of our sales now 85%-90% of our sales to the battery market. That's really gonna be the focus for us there. We do wanna grow volumes. We have some opportunities to do so at Nickel West. You've seen the investment we've made, small investment that we've made into a project in Tanzania.
We're also looking at how we can go about enhancing value for the nickel units that we're already selling. That's come through you know, the development of this nickel sulphate plant at Kwinana. We realized first crystals coming out of that in the past period. We hope to see that, you know, well, that will add more to our margins in the periods ahead.
Excellent. Okay. Thanks, Mike. Thank you.
Your next question comes from Robert Stein of CLSA. Please ask your question.
Hi, Mike and team. Firstly, congrats on the great result, especially cost control in the Pilbara, in this environment. I've got two questions, both on capital allocation and inorganic growth. The first question is on net debt at $6 billion, currently represents 3% of the current EV. Is that overly conservative given the cash generation potential of the business both in the last half but then also for, you know, potentially for this half given where spot pricing is? The second question is around M&A and considering that in the capital allocation framework, now that we've collapsed the DLC, does offering scrip as a way to acquire assets offer a different risk return framework for how you consider M&A, given crystallizing prices for cash at cyclical highs may not be the most prudent way forward?
Okay. David, I'm gonna talk just very briefly to M&A then net debt, and then I'll pass to you because I know you'll have further to add on net debt. Robert, just on your question around, you know, having collapsed the DLC, does it change the equation then in terms of risk returns and give us more ability to do scrip-based acquisitions? I should be clear, we've always had the ability to do scrip-based acquisitions if we so wished. They were just harder in the past. We'd be slower, there would be more complication associated with them. This will free us up to be more commercial and agile.
This is a big caveat, we're only gonna pursue the right opportunities at the right time and at the right price because we do have a strategy where we intend to grow value, but our means to growing value come through driving better performance out of the business that we already have. Looking at how we can go about liberating more of these huge resources that we have in copper and nickel already, so how we can go about unlocking more of them more quickly at good returns. We've then upped our effort in exploration and early stage entry.
You know, if we do identify the right opportunity or the right opportunity comes along, then of course, you know, we'd be looking at cash versus scrip and so on. But I really do want to emphasize that the way that we think about growth in this company is multifaceted, and it starts with driving better performance out of the current business and looking at unlocking more current resources. But we have upped our effort on a number of those other dimensions as well. Now on net debt, you know, your question was, are we being overly conservative on kind of net debt? And I assume that the flip side of that is returns to shareholders.
I look at it, you know, if we were, we don't believe we are, but if we were, it's a six-month issue because we reconsider this every six months. If cash generation continues to be as strong as it's been in the period ahead, well in six months time, that'll play into the thinking around returns to shareholders at that time. David, anything you'd like to add?
Other than just to say that we obviously want to maintain a resilient balance sheet and we're mindful of uncertainties. Some of those play out in the context of Samarco and where our liability is in that regard. But equally, what I would say to you is you referenced the $6 billion and the 3% of EV. I mean, obviously that's towards the bottom end of that $5 billion-$15 billion range. When we actually then pay out the $7.6 billion of dividend this time around, we'll move up towards the top end of that current $5 billion-$15 billion range. As Mike said, it's a six-monthly exercise that we look at and determine what's appropriate given that the outlooks that we see and the uncertainties at that point in time.
Thank you. Perhaps just a quick follow-up. The $5 billion-$15 billion is an interperiod range rather than an end-of-period range. How should we think about that in terms of cash outflows and dividends?
It's a range that we're looking to manage the balance sheet to within, you know, the periods that we're talking about. It's something that we reflect on half yearly when we look at the return to investors as part of that. Certainly we're looking to maintain throughout all periods, $5 billion-$15 billion.
Thank you.
Your next question comes from Paul McTaggart of Citigroup. Please ask your question.
Morning, guys. It seems like all the roads lead to Rome in the sense that many of the questions are getting at the same thing. You know, in the past, petroleum was gonna be one of your growth areas. That's obviously gonna go. If you think about Escondida, I mean, in the long run we have grade decline, so we know we need to expand concentrator output just to offset grade decline. It's not clear to me that in the current portfolio you've really got growth opportunities that are meaningful in the scale of the current profit line. That sort of gets to the question about how you think about M&A, et cetera. How should we think about what your vision is, Mike, for the future?
Are you looking for a fourth strong arm for the company, or are you happy if you can't find the right deal, that you'll just return cash to investors either via the dividends or buybacks? I mean, I'm trying to get a sense of your vision for what needs to happen to BHP on a five-year view.
Okay. Let me address the back end of your question first around, you know, are we happy to return cash to shareholders if we don't find the right opportunity? Absolutely, yes. We will not pursue things here just for the sake of creating a new business or just for the sake of growth. You know, we've got a multi-year track record now of being very, very disciplined when it comes to capital allocation framework. That's not going to change. Anything we do, be it internal growth, you know, capital projects internally, I'll come to that in a second, or M&A, has to stack up under the capital allocation framework. One alternative under the capital allocation framework is to return, you know, further cash to shareholders.
Now having said that, we do have an aspiration to grow for good, real good value and returns. The levers available to us to do so are one, continuing to drive more out of the business that we currently have, and that's a combination of high productivity, but also looking at further debottlenecking and brownfield expansions within the current resources. We have some early thoughts and concepts around further opportunities to do so, and there is a slide in the pack that outlines some of those.
There's further work to be done and the teams have increased the amount of spend on project studies internally, including at Escondida, to look at how we can go about unlocking more of this, you know, these great resources that we have in copper and nickel. You know, I was looking at the numbers earlier today and 45 billion tons of inferred resource. It's at one end, but sitting at just under 0.6% copper from memory. We've got the world's second-largest nickel sulfide resource as well. I'm confident that we'll be able to secure more options within the resource that we already have in time.
I also recognize that we, you know, we would like to be able to secure more options over and above that through things like exploration and early-stage entry. We've had some great wins on that front in the course of the past six months with more partnerships in place. You've seen the small investment we've made in this, you know, the world's best undeveloped but close to being developed nickel sulfide deposit in Tanzania. Then comes M&A. For the right opportunity in the right construct at the right price, we have a foundation now that allows us to pursue that sort of opportunity, but at all times with discipline and with it being put through the wringer of the capital allocation framework.
Your next question comes from Glyn Lawcock of Barrenjoey. Please ask your question.
Good morning, Mike. Two quick questions from me. Firstly, in your opening remarks, you made some comment that said inflation that is demand led is positive for pricing. I would have put lithium in that bucket. Just wondering if you could maybe comment on how your views about the market not being big enough, the cost curve not being steep enough, and lithium may be changing, if at all. The second question is, just on the decarbonization spend. I mean, I think the company's talked about $2 billion-$4 billion by end of the decade. Some of your peers have already talked about building their own solar and wind in the Pilbara with some pretty ritzy capital numbers. Just what's BHP's intent? How are you thinking about in-house versus perhaps outsourcing through power purchase agreements, et cetera? Thanks.
Okay. Thanks for the questions, Glyn. On lithium, you know, the statement around demand-led inflation, all other things being equal, leading, you know, being positive for commodity prices, that's a broad statement and applies to most commodities. But of course, it's not just a demand-side question. We also have to look at the supply side. You know, our views around lithium have been less about market size because I think, you know, all factors point to the market size growing over time and it becoming, you know, of a sufficient materiality to be of interest.
We do view the cost curve as being flat and therefore haven't been able to see our way through to, you know, it being an industry with good, strong long-term margins of the like that we would see in other commodities. That view hasn't changed. You know, we review these things regularly. On decarbonization spend, we've said we're, you know, we'll be at the upper end of that $2 billion-$4 billion range. So let's say $4 billion or close to that. Importantly, we look at all of this spend on a returns basis. So current numbers indicate that we'd be about -$500 million NPV on that $4 billion spend.
The challenge that we've set ourselves is to get back to NPV neutral or better, because all of these projects compete for capital under the capital allocation framework as well. Now, the point that you raised around what are we going to do in-house versus contract out, one key area where we do have the ability to go to third parties to help us decarbonize is stationary power, and that comprises about 40% of our kind of decarbonization target. We've done that to great effect through our Chilean operations, which has underpinned the 16% period-on-period decrease in Scope 1 and Scope 2 emissions. You know, we'll certainly look at those alternatives as well for the Pilbara.
Okay, thanks, Mike.
Your next question comes from Peter O'Connor of Shaw and Partners. Please ask your question.
Good morning, Mike. Good morning, David. First on portfolio optimization, Mike, I wanted to pick up on a thread that we talked about a little while ago. Two assets in your portfolio account for about 33% of your net operating assets. That's BMA in Queensland and Olympic Dam. You've talked a lot about portfolio optimization and productivity, which I admire, and I think that's a tremendous way forward. How can you unlock those two businesses to get a reasonable or an acceptable return on capital? Is that achievable? Do you need more asset turns or do you need lower costs or do you need both? And will you actually be able to do that given the track record of the past decades? And I've got a second follow-up.
Okay. Look, let's take that one first then. Peter, look, two very different businesses, obviously. In the case of Queensland, it is just kind of day-to-day continuous improvement. Again, we have had the noise of things like weather and COVID. Even if I adjust for those, there's more that we can do in that business in terms of driving productivity without a doubt. It'll be things like improved truck cycle time, improved kind of discipline when it comes to mine planning and compliance to plan. We built the capability to be able to do that.
With the advent of autonomous haulage in Queensland, that's going to help us drive that truck shovel productivity as well, which is a bottleneck in that business. Olympic Dam, different kettle of fish. Olympic Dam, we've been on a multi-year journey now around rectifying kind of a legacy of underinvestment in asset integrity. We're at the very back end of that now with SCM 21. The smelter's come back online, performing well. The combination of the improved productivity that we're seeing on the surface and the underground is already leading to improved operational performance. You saw that last year with the record production under BHP's stewardship.
Because the capital base at Olympic Dam is so high, even with that very, solid performance, return on capital employed was still low. The long-term way of increasing returns at Olympic Dam is through further growing production. There's some things that we can do around minor debottlenecking to allow us to increase production a bit further. For there to be a significant change in returns there, it does require a long-term way of further unlocking that resource. That may come through Olympic Dam, it may come through Oak Dam or a combination of the two. We haven't, you know, we continue to look at that in the background, but none of that's gonna happen if the base business isn't running well. That's what we've been focused on and are starting to see the success shine through on. Peter, you had a second question as well?
Yeah. Can I shift gears to dividends and dividend payout policy? Your capital allocation framework is very clear and has been for the last six years, and the base payout ratio of 50% where you all work from. Looking at your average of the last five or six years, I think it's running about 74%. Just thinking about how that drops out of the policy a bit more looking ahead. With growth in the company, additional capital calls, maybe M&A, inorganic stuff, payout ratio is staying well above that 50%. How do we think about that beyond just the short-term large cash flows you're generating?
David, do you wanna take that one?
Peter, as we have said, we look at this on a six-monthly basis, and we're committed to that 50% minimum. Over and above that, it's an assessment of how much do we wish to reinvest back into the business to maintain that resilient operations which we've seen, which clearly we look to do, but also look to grow the company. It's a balance every six months that we review that. What I think you're flagging is, to date, what we are saying is we're not gonna sit on the cash.
We have that net debt range, and we will return money to shareholders as we have done, you know, going back to what the $22 billion just paid out over the last 18 months, or declared and about to be paid out over the last 18 months, which is a demonstration of returning money to maintain the discipline. I think the key through the capital allocation framework is to ensure that we maintain that discipline that exists. It's a matter of assessing both internal and external opportunities. It's about managing the risks that we see through that versus returning money to shareholders, and that's what we continue to actually look at.
I think, you know, so if I just add one thing, Peter. We've shown that we have, you know, shareholder interest strongly at heart so that, you know, the combination of disciplined application of capital allocation framework, keen eye on shareholder interest. You know, I'd ask that, you know, people take some confidence then in decisions that we'll make along the way.
Mike, can I just push back, and the policy's been in place for six years, seven years, and it basically has a 50% average, call it 75%. Is that the right number, 75%, not 50%? Should you rebase the policy? Are you being too cute? If not, should investors not capitalize current levels of dividends and capitalize the future, dividend stream from BHP at 50%?
We continue to believe that the 50% is appropriate. This is a long-term industry. We go through cycles, both cycles of growth and reinvestment in the business as well as market cycles. We still believe 50% is the right level. We're as transparent as we can be with the market about how we see forward production levels, growth projects, and so on. Conversely, if we were reinvesting more back into the business, that's likely going to be to lift long-term production levels.
I would say that the, you know, either way, as long as we're applying the cap in a disciplined fashion, shareholders should see or be able to capitalize on higher cash returns or reinvestment in the business and higher growth, which leads to longer term higher cash returns. You'll have to rely upon our constant reporting and transparency around our plans and where the cash is flowing to.
Thank you.
The next question comes from Rahul Anand of Morgan Stanley. Please ask your question.
Hi. Thank you. Hi, Mike, David, and Tristan, plus team. Two questions from me. First one, David, if I can labor the point on net debt range a bit more, if I may. Look, I just wanted to understand in terms of the bounds, once you start going outside these bounds. On the bottom end, firstly, if you are sitting below that bottom end comfortably, can we assume that capital comes back to shareholders? Then once you do decide to go above that top end of the range, what would dictate how much over you go in a transformational transaction? Is it fair to think that would be driven by that investment-grade credit rating? That's the first question. Second one's on copper. I'll come back with that, if that's okay.
Let me deal with the range and specifically your question around the credit rating side of things. I mean, clearly what we're looking to do is maintain a resilient balance sheet, and credit metrics are one way for you to assess how that's playing out. From our side of things, you know, we also need to look at what we see around the future and how the businesses are performing, the uncertainty that exists there, as I flagged earlier, also in relation to the Samarco liabilities, et cetera.
There's a number of factors that we actually look at when we're looking at the overall range, and where we feel comfortable at any six-month period when we assess the dividends as to where we wanna land within that range. Your question around if we're at the bottom end, below the five, is it appropriate to think that that would be returned to shareholders? Yes, because we would look to see how we're looking into that range. I would again, though, come back to, you know, it's a bit back to Peter's question. The capital allocation framework has been in place since 2016 and has allowed the company to deliver hugely to the position that we're actually in at the moment.
You know, the balance sheet is in a very healthy position, and that gives us the opportunity to think about how much do we reinvest back into the business versus looking at organic growth opportunities or any external growth opportunities as well. They're all the factors that we'll look at on a six monthly basis to determine whether we wanna actually sit in relation to that $5 billion-$15 billion range. The range is there to give you an indication of where we would be from a capital return side of things. In relation to how we would assess going above the top end of that really comes down to the opportunity. You know, we don't have a generic view around that.
That would be based on the specifics of anything that we were looking at from an M&A perspective and how would that play out. We would look at how quickly could we necessarily return back into that, net debt range, but also obviously with a core focus to how does it add to overall shareholder value and over what time period. You know, we don't have a generic response to that. It would be specific based on any opportunity, as we assess at that time.
Perfect. Thank you.
You had a second question on copper?
Second one. Yes, I do, Mike, that one's for you. Look, I wanted to talk about the copper production in South America in the near term and the medium term. The near term, obviously the average at Pampa Norte, the average 300,000 tons per annum guidance. You've had some issues with recoveries at SGO. I just wanted to understand if the critical items, you know, the orders are in place for you to be able to get to that number. The longer-term question in terms of copper is around Escondida. I just wanted to understand, post the grade decline, what's the plan? Is it to allow that production to taper off in line? Do you expect to, you know, spend more CapEx and increase concentrator capacity there, to be able to keep that production at a level which is higher than what grade would dictate?
Sure. Okay. Look, both good questions. So in the case of SGO, you asked very specifically, are orders in place? Yes. And the short answer is no, because it's, you know, its project has only recently been commissioned, obviously. We have had a period now of running it. We have achieved, you know, full throughput levels in terms of volume over the month of December, so we're confident that the throughput is there. The issue is recoveries. We have a pretty good understanding of what's gonna be required of the plant modifications, which are all manageable, that are gonna be required to get to the full production rate. We're still early on in that project planning phase.
Exactly when we'll get to full production rate is subject a little bit to where we ultimately land in terms of the project and execution schedule and so on. We can say with confidence that we will ultimately get to the original intended levels of production. Keep in mind, this is a long-term resource. This is a 50-year project. It's not, you know, it's not something that just impacts the next or the opportunity isn't just in the next couple of years. We're confident that the long-term payoff is there. Now, in terms of Escondida, what's the plan?
Rag and the team have been very focused on looking at developing more options for how we go about addressing the long-term grade decline that kicks in post the kind of the five-year window at Escondida. Big resource of course. We do know that there's gonna be a number of options available to us, but they all have to you know, be adequate or attractive from a returns perspective as well. That's really where the focus is at currently, is on proving that up. I know we'll have more to say about that in you know, in due course. Suffice to say at this point that the team's beavering away at a number of project concepts in and around Escondida and, you know, at Spence and so on.
Perfect. Look forward to that visibility. Thank you very much. I'll pass it on.
Your next question comes from Lachlan Shaw of UBS. Please ask your question.
Good morning, Mike and David. Thanks for the update and congratulations on the results. Just a couple of questions from me. Just firstly, in terms of the work around decarbonizing Scope 1 and 2 in Western Australia Iron Ore, just interested if there have been any updates on studies around beneficiation of fines and I guess more generally, updates on your expectations of CapEx required sort of looking out into the medium term. I'll come back with a second question later.
Okay. Just can I confirm on the CapEx, you mean the CapEx associated with decarbonization?
Yeah, also the potential studies side of things around possible beneficiation at Jimblebar.
Oh, I see. Sure. Okay. No update on beneficiation other than the Jimblebar, the study at Jimblebar, continues. I don't think, David, we've given any numbers around-
No.
around CapEx. I will just say that Jimblebar is an ore that lends itself well to beneficiation and being able to generate returns off the back of that. Still too early in the process to give specifics around schedule and cost and so on. In terms of overall CapEx for decarbonization, we have said that we expect now to be at the upper end of the $2 billion-$4 billion range. For returns, you know, kind of on paper currently of about - $500 million NPV. So $4 billion CapEx - $500 million NPV. A lot of work underway to get that back to being NPV neutral or better, keeping in mind that all of these projects have to compete for capital under the capital allocation framework.
Got it.
Your next question comes from Kaan Peker of Royal Bank of Canada. Please ask your question.
Happy new year, Mike and David. Two questions from me. The first one's just on future pricing commodities, especially because I think in December you decided not to increase or extend your offer for Noront. I understand the argument about not paying too much. Just wanted to sort of understand the specific appeal in Noront, the geology, the basin, the possible size. With the Noront acquisition not being progressed, is there any read-through from Nickel West? I mean, will you bring forward any projects such as Honeymoon Well or the smelter upgrade? I'll circle back with a second question. Thanks.
Sure. Okay. Look, we were clear at the time that we saw Noront as being attractive in its own right, but also because it's, you know, part of a basin. It was a very early stage play with all the risks that come with that, but we could see our way through to there being a potentially attractive opportunity there. We have to be disciplined. You know, we've spent five or six years now building up trust and a track record of being very disciplined when it comes to application of the cap, and you saw that in its full glory in and around Noront. Now, what are the implications for Nickel West? I wouldn't. There's no direct implications.
We were looking at opportunities to further improve value from Nickel West before we looked at Noront. We've continued to look at opportunities since. Where do those opportunities lie? Number one, let's increase the margin that we secure on existing production. We've done that through pivoting into the battery raw materials market. 85%-90% of sales now going there. We've upgraded products through the first nickel sulfate plant, which will give us more margin for the nickel units that we're selling. We are looking at things like what we do with the smelter longer term and whether there's an opportunity in there to deconstrain the operation in terms of ore quality and so on.
Quite a few things that the team's looking at there. The HPAL leaching project as well, which I'm confident that over time are going to allow us to grow value off of Nickel West. We're also. We've got further efforts underway on the exploration front, both in WA and elsewhere. You saw our small investment into a nickel sulfide project in Tanzania recently. You had a second question as well?
Yes, thanks. It's on the iron ore business. Circling back to Hayden's question, I think on slide 30, the medium-term target is 2 90. I understand the focus is on sustainably achieving 290 in costs, but I think, Mike, you've mentioned that you could possibly get to 300 and 310 in the medium term. Just wanted to get clarity on this, you know, in terms of timeframe. What does medium term mean? Is it 2024 when South Flank ramps up? I think you talked about the debottlenecking program underway. What are the key components there we should be focusing on? Thanks.
You know, I've been clear that the plans at this point are to sustainably get to 290, but I've also recognized that the team is doing such a wonderful job there that all things going well, continuing reliable operations, bit of improvement on productivity, and some debottlenecking things that I'll come to in a second. There's every potential that we would end up creeping beyond 290, let's say to the, you know, to kind of that 300, 310 level, but no plans in place for a major capital program to get us to the 330. We have the flexibility to be able to do that with the new allocation, but there's no plans in place to do that. We'll always be guided by the way that markets are unfolding.
Now, what are the key components of debottlenecking? First and foremost, it's rail. We are looking at how we go about increasing capacity on the rail and safety through the implementation of a new signaling system. There's a bit at the port itself, where we've been looking to improve car dumper reliability and so on at the port to give us more port capacity. If we were ever going to lift production and throughput at WAIO more significantly, that'll require further work at the port, potentially another car dumper and some work on the yards and so on. Again, that's not the current plan.
Your next question comes from Lyndon Fagan of JP Morgan. Please ask your question.
Thanks very much. The first one is just on BHP's view around flat steel production in China this year. Just wondering if you could maybe provide a bit more granularity there, given the slowdown in the property sector and what gives you confidence around a flat outcome for the year? The next one was just to sort of dive into Chile a bit more. There's been proposals to nationalize assets over there, and I think we'll end up with a royalty increase of some sort. I'm wondering if you could maybe give us a bit of an overview of how you see the situation playing out. Thanks.
Okay. David, do you wanna comment on steel and, I'll take Chile?
Yes, certainly. So, Lyndon, just in specifically in relation to China and the property side of things, we are seeing some recovery coming through there. Again, I'd point you towards credit side of things within China, et cetera. What we would've said in the six months just gone, China came off probably quicker than what we had anticipated, but we certainly see some recovery coming through there. For the fourth consecutive year, we do see, you know, over a billion of steel coming through from China. You know, that's sort of how we're seeing things play out in China at this point. A little bit of recovery, if you like, in the short term.
Now, on your question about Chile and royalties. Clearly a big process underway around the constitution, but also looking at royalty increases there. We expect that that'll come through, those discussions will be landed post March with the new government, the new Congress. Now at the start of this process, there were some more extreme calls around what a royalty increase might look like. I think more balanced voices have come into the debate. There's a broad understanding or a building understanding around the criticality of the copper industry to the nation and the national economy. Knowledge that at the end of the day, Chile needs to compete for capital. You know, there's been earlier questions on this call about grade decline and so on.
The only way that the nation will be able to address that grade decline is through attracting more investment. It can only attract more investment if it has the right fiscal settings. I think that's, you know, there has been a growing recognition around that such that the more recent proposals and thinking around royalty increases are more measured, let's put it that way. Not yet finalized, but signs are emerging that there's a more balanced perspective being brought to bear on this. Now, the only further thing I would add is we have in place, of course, tax stability agreements that give us certainty or delay the changes for BHP's operations for a period of time, shorter for Escondida than for Spence. David, I think it's out to 2023 from memory for Escondida.
Yeah.
We have a tax stability agreement in place, and then it's further out for Spence.
Spence is 2032.
2032. Okay.
Thanks for that. Just a quick follow-up related. Can you maybe provide some broad indication of the cost to rectify the Spence design issue?
All I'd wanna say on that one at this point, Lyndon, is that it's manageable. We're still looking at things, but it's, you know, going to be, you know, possibly one extra flotation circuit, but certainly manageable both in timeframe and in cost, but not yet fully nutted out.
Thanks, Mike.
Thank you. Your next question comes from James Redfern of Bank of America. Please ask your question.
Hi again. I just wanna ask a question on New South Wales Energy Coal. Obviously, you had a big improvement in profitability, EBITDA of $435.5 million compared to a loss of $180 million in the previous half. And obviously the sale process or review is still ongoing. It has until August to complete. I mean, is there any chance you could please give us an update on how that's progressing? I mean, is this asset being held a little bit longer to extract more cash flow, or is the sale process, I guess, struggling, if you like? Thank you.
James, you know, at the time that we embarked on this process, we recognized that, you know, these processes, particularly for coal assets, can be a little bit more complicated. We've got three of them away, one more to go, but still within the two-year window that we gave ourselves. There's been no proactive decision here to hang on to things a bit longer, given where market prices are at. Of course, happy that it's the asset is generating a lot more value now, but that's not what's driving the timeline. As to the where to from here, I'd say just, you know, you can be certain that we'll come back with further in once the two-year process is up. Until then, not much more to add.
Okay, thank you.
Your next question comes from Glyn Lawcock of Barrenjoey. Please ask your question.
Hi, Mike. Just a quick one. We spent a lot of time today talking about capital returns, but there's obviously multiple ways, and you've chosen just to continue to pay a higher than your minimum 50%. How do you think about it then when you sat down this last couple of weeks to versus, say, a buyback, given now the DLC has collapsed, we don't have to go offshore to buy back their stock to keep it equal. You know, how did you approach your thoughts around, you know, the off market versus, you know, the increased payout? Thanks.
Great. Thanks, Glyn. Obviously, clearly something we consider every six months. We have had pretty healthy returns and that's continued in this period. David, maybe you just wanna talk about the framework that we kind of bring to bear on thinking about this and how we landed it where we landed.
Yeah. Thanks, Glyn, for the question. Clearly, it starts with how much. We firstly look at what is the return that we think is appropriate given the capital allocation framework and given the net debt range, et cetera. We look at what's the most efficient way to get that back to shareholders. Clearly, a buyback is one of the things that we look at, whether that's on-market or off-market, we consider those. At this point in time, we felt the best way to return and keep things for all shareholders was actually the cash dividend. That's where we landed from an overall perspective. That's, you know, where we resituate ourselves alongside balancing out the various different demands of shareholders as part of that overall process.
I would just say, you know, as part of that, again, come back to $22 billion returned in the last 18 months. It's been a great return to shareholders, and we think that's consistent with the application of the capital allocation framework.
I understand that. Can I just challenge you a little bit more then? I mean, a 14% discount for an off-market, you know, am I interpreting therefore that that's not attractive entry point into the shares versus just returning cash?
That goes into that framework that we assess things on from our point of view. As I said, we felt that it was appropriate to return a cash dividend to all shareholders in the form that we did, and felt that was the best way to return money to shareholders this time around. It is something that we assess on a six-monthly basis and will continue to do so.
I think the important point there, Glyn, is that there's a number of parameters that we consider, kind of where shareholders are at overall in terms of sentiments, the broad base of shareholders, and so on. It's but one factor, and as David said, taking all of that into account, the board decided this time around to go with all cash, but we'll consider it in six months' time.
All right. Thanks again. Appreciate it.
Your next question comes from Lachlan Shaw of UBS. Please ask your question.
Thanks, guys. Just a follow-up question from me. Just around your commentary around the outlook for many commodities, quite strong demand, low supply, low inventory in respect of copper particularly. Just thinking about the improvement we've seen in the uranium market recently. You talked about Olympic Dam, Oak Dam, optionality there, the importance of getting the asset producing reliably. Is there any sort of, you know, update there on timing and potential scope of how, you know, how those sort of projects in that province may come together in the short to medium term?
Short answer is no. To be totally transparent, I don't want to get ahead of ourselves in terms of painting a growth outlook for Olympic Dam at this point, given you know some of the scars of the past. All I can say is that any growth ambitions we have around Olympic Dam won't happen unless the base business is running well. That has been 90% of the focus of recent times, and you see it shining through. But of course, we continue to look at what more we can do with this large resource at Olympic Dam, and now we've got the added plus of Oak Dam.
In the case of Olympic Dam, there is further drilling underway to tell us exactly what we have. Then in the coming few years, we'll look at whether we can turn all of that into, you know, a high returning growth opportunity for us in copper. Of course, it will be aided if we have the tailwinds of higher uranium prices. That's probably it for now. Once we have greater confidence around things, I'm sure we'll come back and talk about exactly what that might look like and when, but not for now.
Thanks, bye.
Your next question comes from Peter O'Connor of Shaw and Partners. Please ask your question.
Mike, can I just go back to the answer about the buyback versus dividends question from Glyn Lawcock, just to clarify. Is part of the decision tree in deciding on a buyback as part of that process, does it involve a hurdle which is share price versus your assessment of NPV of the shares?
Peter, I understand the question. I mean, again, there's several factors that we contribute to the decision as to whether it's a cash dividend or whether it's a buyback as part of the process. As I said, we evaluate that on a six-month basis, and through the Capital Allocation Framework, that's the mechanism that we use. We obviously, as part of that, are conscious of where the share price is at, yes. You'd expect us to factor that into the equation. Having said that, this time around, we felt that it was more appropriate to return a cash dividend, with all things balanced out, as we look at where we were also with the revised range and where we are also in relation to, you know, the ongoing organic growth options that we have.
I think if I cut to the chase, you know, Peter's question, Glyn's question, really at the heart of it is, do you think your share price, your shares are overvalued? Short answer, no. Very happy that they've rallied since their lows. Tristan, when was that? Back in November, thereabout. Shares have rallied. This really is a decision. It's not a spreadsheet-driven decision. There is a value component to it, but there's a whole host of other factors that come into the decision about what the best option is at any given six-month period.
With that, operator.
Can I just follow up?
Sorry, yeah. Go on.
Can I frame this question, Mike, in terms of, yeah, nickel. You've mentioned several times about nickel being the second largest resource of nickel sulfate in the world. Thinking about the future and adding in Kabanga and the IP that you may pick up there in terms of a move towards hydrometallurgy, and you mentioned HPAL as well. How does WA Nickel West unfold? Is pyrometallurgy part of that process? And if so, for how long? Or is hydrometallurgy the way to go? And is that the way you unlock the resource?
Way, way too early for us to know, Peter. All I can say is that you know, more so than, you know, I think of all the BHP businesses that are where we're at the advent of bringing innovation to bear on how we unlock more value, Nickel West is right up there. That includes the nickel sulphate plant that we've developed some of the things like HPAL that we're looking at. I think innovation does hold within it quite a bit of potential around Nickel West, but too early at this point to be calling for, you know, what is going to be the winning technologies and the approaches.
With that, operator, just wanted to thank everyone for joining the call earlier today. If anyone's got any questions, feel free to ask us in the Investor Relations team. With that, we'll call it a day.
Thanks, all.
Thanks, everyone.
