Earnings Call: H1 2024

Feb 23, 2024

Operator

Thank you for standing by and welcome to the Sandfire Resources first half FY 2024 results call. All participants are in a listen-only mode. There will be a presentation followed by a question-and-answer session. If you wish to ask a question, you will need to press the star key followed by the number one on your telephone keypad. I would now like to hand the conference over to Mr. Brendan Harris, Chief Executive Officer and Managing Director. Please go ahead.

Brendan Harris
CEO and Managing Director, Sandfire Resources

Hello and good morning. I'd like to acknowledge the traditional custodians of the land on which we stand, the Whadjuk people of the Noongar Nation, as well as the First Nations peoples of the lands on which Sandfire conducts its business. We pay our respects to their elders and leaders, past, present, and emerging. My name is Brendan Harris, CEO of Sandfire Resources. I'd like to welcome you to our half-year financial results conference call. We're fortunate to have the opportunity to connect with you again so soon after our December quarterly call. I'm joined here in Perth by my colleagues Megan Jansen, Jason Grace, Cath Bozanich, Victoria Twiss, and Scott Browne. Richard Holmes is currently in transit and sends his apologies. Guided by our new shared purpose, we mine copper sustainably to energize the future.

We are hitting critical milestones and remain strongly placed to support the electrification and decarbonization of the global economy. Nothing is more important than the health and well-being of our people. Our unrelenting focus on safety delivered a TRIF of 1.5 at the end of the period, down from 1.6 at the end of the prior financial year. Through strong leadership on the ground, we will further instill our don't-walk-past operating philosophy and enhance our robust hazard management systems and processes. Similarly, our broader ESG framework must permeate everything we do. As I mentioned on our last conference call, we were pleased to announce the signing of the framework agreement between Sandfire and the Yugunga-Nya at the end of December. This was an important first step toward rebuilding our relationship with the Yugunga-Nya and ensuring the ongoing protection of cultural heritage at our DeGrussa operation.

Our decision to retain DeGrussa and rehabilitate the operation means we will have an important presence in the region for many years to come, and we look forward to working with the Yugunga-Nya, government and our other stakeholders to deliver meaningful, sustainable outcomes for the community. Megan, over to you to walk through our financial performance for the December 2023 half-year.

Megan Jansen
CFO, Sandfire Resources

Thanks, Brendan. I'm very pleased to present our financial results for the first time. As we said when we reported our quarterly numbers at the end of January, we've maintained our production cost and capital guidance for FY 2024. Growing consistency and predictability at MATSA and continued outperformance at Motheo underpinned copper equivalent production of 63.2 thousand tonnes in the first half, which in turn generated sales revenue of $418 million and underlying operations EBITDA of $165 million for an underlying operations margin of 40%. Operating discipline and robust cost control was a feature of these results as we continue to mitigate broader inflationary pressure at MATSA with mine operating costs remaining stable at $72 per tonne of ore processed.

The operation benefited from broader economies of scale and near 45% reduction in power costs and optimization of consumables usage, all of which abated the impact of adverse foreign exchange rates.

By signing an agreement with Endesa for the construction of a dedicated solar facility that will supply around 25% of MATSA's overall electricity requirements progressively from calendar year 2025, we have further improved our long-term energy supply mix and reinforced the low-carbon credentials of MATSA's metal concentrates. Motheo reported an underlying mine operating cost of $39 per tonne in its first six months of commercial production, reflecting good cost control as the operation ramped up to its interim capacity of 3.2 million tonnes per annum. Below the line, our depreciation and amortization expense remains elevated at $149.1 million following the $1.9 billion acquisition of MATSA in FY 2022. You will also have seen that we have expensed interest associated with the $200 million Motheo finance facility for the first time as our newest mine achieved commercial production at the start of the period.

Our overall net interest expense reflects our level of debt and the margin embedded in our various finance facilities. Noting interest associated with the $60 million A4 mine development will be expensed rather than capitalized when the open pit achieves commercial production planned for the September 2024 quarter. While our underlying loss increased by $17.2 million in the period, underlying group EBITDA declined by a more modest $2.4 million despite the cessation of processing activities at DeGrussa in May 2023 and its $80.8 million contribution to underlying group EBITDA in the prior corresponding period. This was only possible because the commissioning and ramp-up of Motheo added around $50 million to underlying group EBITDA at an operating margin of 43% in its first six full months of operation.

With the ramp-up of Motheo and delivery of our intentionally simple strategy, we expect to return the business to profitability and pay down debt in the coming years. With regard to our balance sheet, we ended the period with a cash balance of $105 million and net debt of $476 million, which included $401 million owing under the MATSA finance facility and $180 million owing under the Motheo finance facility with the successful commissioning of the new Ball Mill at Motheo completed just prior to Christmas and the A4 development set to be completed in the current half. We project strong production growth into FY 2025 and a further decline in capital expenditure with net debt expected to peak during the current half-year.

Indeed, I can confirm that net debt at the end of January declined to $ 459 million as we received cash associated with the Motheo December shipment that was loaded very late in the prior half-year. Furthermore, I'm very pleased to confirm that we have made significant progress in our efforts to modernize the structure of the group's debt facilities by securing credit approval for a $ 200 million Corporate Revolver Facility in early February. Establishment of this revolver is an important step for Sandfire as a global business. The new facility will increase the financial flexibility of the group, reduce our near-term debt repayment profile, and be primarily used to repay the remaining $ 88 million balance of MATSA Facility A. The establishment of this facility is subject to final documentation and standard conditions and is on track to be finalized before the end of March.

This excellent outcome gives us even greater confidence to invest in the future of our business. Let's look at our plans for CapEx. Total capital expenditure in the half decreased to $99 million as construction of the 3.2 million tonne per annum first phase development of Motheo was largely completed in the prior financial year. Our rapid and low-cost expansion of Motheo remains on time and on budget with the A4 development expected to be completed in the current half as planned. Mine development expenditure included $41 million at MATSA in the period as we sought to progressively open additional mining fronts and provide increased flexibility in our underground mines. With that, I'll hand back to Brendan.

Brendan Harris
CEO and Managing Director, Sandfire Resources

Thanks, Megan, and great work. Before I close and ask for questions, let's quickly turn back to Motheo. Our newest mine has started life in rude health, exceeding its initial 3.2 million tonne per annum capacity by almost 10% in only its second full quarter of operation, producing 16,800 tonnes of copper and 396,000 ounces of silver for copper equivalent production of 17,900 tonnes. As Megan mentioned, the last major milestone in the rapid and low-cost expansion to 5.2 million tonnes per annum was achieved in late December with commissioning of the ball mill and the maximum daily processing rate, as you know, of 627 tonnes per hour was subsequently achieved. What I can tell you is the positive trend has continued with a further uplift in the average processing rate to 4.3 million tonnes per annum achieved in January.

As you'd expect, we are now focused on achieving the facility's 5.2 million tonne per annum nameplate rate on a sustainable basis before testing its ultimate potential. So on this basis, we remain exceptionally well-positioned to deliver into an increasingly tight copper market with more than 50% growth in copper equivalent production projected across the two years to the end of FY 2025 from our continuing operations. Having sought to avoid repetition from our recent quarterly call, let's get stuck into your questions. May I have the first question, please?

Operator

Thank you. Your first question comes from Manav Shah from Morgan Stanley. Please go ahead.

Rahul Anand
Executive Director, Morgan Stanley

Hi, good morning. Good afternoon. It's Rahul here from Morgan Stanley. Look, I've got a couple there, Brendan and Megan. First one's on the debt facility. So perhaps for Megan, congratulations on refinancing that facility. I just wanted to get a bit of understanding in terms of what type of interest rates we should think about this versus your current net debt balance. And then in terms of any sort of covenants, etc., that are associated with this debt, please. That's the first one.

Megan Jansen
CFO, Sandfire Resources

Okay. I'll take that one. Thanks for the question, Rahul. So as you'd appreciate, we can't go into the specifics on the facility's margin, but to give you a broad sense really across the debt portfolio is probably appropriate at this point. From a weighted average interest expense perspective, I'd guide a margin of a range of 2.7%-3% across the debt portfolio for the group. And that should just help with understanding interest expense into the future. Obviously, that'll be impacted the overall expense will be impacted by timing of repayments, prepayments, and the like. But I think a broad weighted margin in that range is reasonable. Covenants, again, we can't go into the specifics of the covenants of this facility. We'll disclose further details as we look to finalize it before the end of March.

What I'd say at this point is the covenants would be typical and standard. So I would expect those to be not dissimilar to traditional lenders'-style covenants that you'd see in other facilities.

Brendan Harris
CEO and Managing Director, Sandfire Resources

And maybe, Rahul, if I can just add, I just don't want us to brush past this. This is an excellent outcome. Megan's obviously been in the job for a short period of time and worked tirelessly on this. We've talked a lot about needing to modernize our debt facilities, the structure of them really to be befitting of a global company. What that really means in code is the ability to move money around the group as we need to. That's what repayment of facility A will do. In terms of rates, the rates on the new facility are very competitive with the current facility A. So it's not going to cause us any, if you like, concern with regards to our expense profile.

The other key point you would have noted, and I think there's an excellent diagram in our slide presentation that shows effectively we significantly reduce our repayment profile out until March 26th, effectively almost 18 months. So that's also another really, really helpful thing for us. Of course, we're not creating value here, so to speak, because, of course, the debt is of an equivalent nature. It's going to remain largely undrawn, the corporate revolver, because the facility A's $88 million. But it really does help us in many ways. So again, as I said, I think this is an excellent outcome for us and something that we've been working on for some time.

Rahul Anand
Executive Director, Morgan Stanley

Got it. Okay. Thanks for that, Brendan. Look, my second question's around slide 22. So you've given the annualised daily milling rates at Motheo. Thanks for that extra detail. I just wanted to touch upon the variability that you've got in that slide right towards the end. Is that purely to do with the commissioning of the ball mill, or is there anything else in terms of the mill that you'd like to report in terms of any sort of hurdles or changes required as you're ramping up?

Brendan Harris
CEO and Managing Director, Sandfire Resources

Yeah. Look, I'll pass to Jason, but maybe just a couple of comments upfront. If you look at that diagram, you'll notice that prior to turning the Ball Mill on, we were starting to get very good levels of consistency, as we said, running well above the interim nameplate capacity of 3.2, i.e., 3.5 across December. It's not unusual as you move into such a significant step up that you will have a degree of variability through that ramp-up commissioning phase because you're well, I'll leave Jason to explain that detail. But primarily, what I'd highlight to you is, again, 4.3 in the quarter sorry, in the month of January is a really good outcome for us in terms of the pathway towards that interim capacity. You'll also note that we've shown very clearly that we can run the facility regularly across days in excess of the 5.2.

And hence, first prize, get to 5.2 and then test the ultimate potential of the operation. But maybe, Jason, to you.

Jason Grace
COO, Sandfire Resources

Yeah. Thanks, Brendan. Thanks, Rahul. You're absolutely right. And particularly with reference to slide 22, you will note the shutdown there around just before the 9th of December 2023. So you can see immediately after that, we were working on rebalancing and, if you like, getting stability back in the circuit. Now, what you're seeing in this graph, and that's why we've put it in there, is really what you expect to see after commissioning, right, of major plant and equipment. So you're doing a lot of mods on the run. You do it rebalancing the whole circuit, and you're trying to get everything back into a stable and almost into equilibrium before you start to push up the overall rates there as well. What we are seeing there as well so you can see the rates that are climbing up, and Brendan touched on that. We are very comfortable.

The mill is going to do 5.2. If you look beyond there and where we're going into February, we are starting to see significant improvements in that overall stability. Yeah, we're very confident we are going to deliver on guidance for the full year out of Motheo.

Rahul Anand
Executive Director, Morgan Stanley

Okay. That's very clear. Thank you very much. If I can sneak in a final one on MATSA, perhaps the TSF. We've talked about it in the second quarter. Just wanted to get an idea of the size and sort of how long does that serve you for, just for modeling purposes. Thanks.

Brendan Harris
CEO and Managing Director, Sandfire Resources

Yeah. Look, it is a significant investment. Jason, maybe over to you.

Jason Grace
COO, Sandfire Resources

Sorry, I missed the first part of that question.

Brendan Harris
CEO and Managing Director, Sandfire Resources

Rahul, do you want to repeat? It's around the tailings facility. But Rahul?

Rahul Anand
Executive Director, Morgan Stanley

Yeah. Yep. So I was just talking about the new tailings facility at MATSA. I think that was flagged in the second quarter of FY 2024. So I just wanted to get an idea of the size and how long it's going to serve you and just be able to think about sort of what type of CapEx and what type of longevity we think about when we're modeling this thing.

Jason Grace
COO, Sandfire Resources

Yeah. In essence, what that does is give us about another two full years of capacity before we start to do further lifts. And you can see at the moment, we've split it into cell one and cell two. The next lift after this cell two construction is around the full envelope of the operations there as well. So we'll progressively start to see that happen about once every two years throughout the life of mine.

Brendan Harris
CEO and Managing Director, Sandfire Resources

That's Motheo and MATSA, just the second TSF that we've got going through permitting?

Jason Grace
COO, Sandfire Resources

Yeah. And the second TSF there as well. So we've got life out until late 2026 in the current TSF, after which we will need to be commissioning the new facility at MATSA there as well. So we'll spend the bulk of that capital required for the MATSA TSF in 2025, 2026.

Brendan Harris
CEO and Managing Director, Sandfire Resources

It's around $ 35 million. Mid-30s is the current estimate. It's out the back, if you like, of the operating areas in terms of where the current facility is. We've got very good support from government. Is our current understanding that bases the engagements that we've had, Rahul.

Rahul Anand
Executive Director, Morgan Stanley

Okay. Brilliant. That's very clear. Thank you very much. I'll pass it on.

Operator

Thank you. Your next question comes from Mitch Ryan from Jefferies. Please go ahead.

Mitch Ryan
Equity Analyst, Jefferies

Thanks, Brendan. Just returning to the Corporate Revolver Facility. I appreciate you can't talk to the covenants of the new facility. But just if you could potentially talk to more what increased optionality it gives you from either an inorganic growth perspective or capital management perspective. I realize that might be in a medium-term focus. But yeah, any color would be appreciated.

Brendan Harris
CEO and Managing Director, Sandfire Resources

Maybe I'll take the first piece of that, Mitch. And hi. Capital management, in the way a corporate thinks about it versus the language the market uses, are two different things. So when we think about that broader capital management, we literally focused on how we move money within the group through our various subsidiaries. You'd imagine with project finance facilities and depending on their nature, timing, etc., when they're established, they have certain requirements or limitations or constraints. Effectively, they're securitized against the asset. And so they have things like cash sweeps. So when you generate excess cash, they take the cream off the top in many cases. And secondly, they will ring-fence capital in circumstances such that you have an inability to return money back to the center.

That's, in effect, one of the biggest opportunities for us with this strategy, of course, is by establishing the corporate revolver. It gives us a nice source of liquidity. It also means, most importantly, as we repay facility A, we can move money back into the corporate center. That's really important for you when you're funding a global business and a corporate office here in Western Australia. That's a really important step for us. In terms of your question around inorganic growth, I can assure you when I look at this revolver, the main objective we have for it is to pay back facility A, to achieve what I've just described, and then to have that undrawn on the balance sheet. Our main objective is to ramp up Motheo. You'll see the EBITDA that it's generating. A4 will be completed by the end of this half-year.

Our capital expenditure starts to decline, and cash will go onto the balance sheet. We'll reduce net debt. Hence, Megan's comments that we see net debt peaking through the current half-year period. So maybe, Megan, I don't know if there's anything you want to add to that.

Megan Jansen
CFO, Sandfire Resources

Thanks, Brendan. And hi, Mitch. I'll add that one of the benefits of the revolver is really around the reduction in the near-term debt profile. And so that sees us repaying MATSA Facility A's $88 million balance now with the drawdown from the revolver. And in essence, that provides an additional sort of $88 million of additional liquidity out to June 2025. And that's what you can see within the diagram that's included with the results presentation. So in essence, it's then deferring that $88 million payment to March 2026, which is the expected maturity date of the new debt.

Mitch Ryan
Equity Analyst, Jefferies

Perfect. Thank you, Crystal Clear. That's it for me.

Brendan Harris
CEO and Managing Director, Sandfire Resources

It's just for me, Mitch, probably summing all of that up. It's just another one of those pieces in the puzzle that you put in place that progressively de-risk the business and put us even in a greater, stronger position to deliver on our strategy, a strategy that we feel investors are starting to see that, if you like, it bears fruit, that focus on the real core basics, predictability, and consistency. Thank you.

Operator

Thank you. Your next question comes from Levi Spry from UBS. Please go ahead.

Levi Spry
Mining Analyst, UBS

Good morning. Good afternoon, Brendan, Megan, Jason. I might just stick on the debt piece if you don't mind. I didn't think we'd all be talking about this, but maybe it's because there's not much else to talk about. What else is there left to do? Why couldn't you do a little bit more? What are the covenants around, I guess, the B facility? How do we think about even the future potential for dividends given that maybe lumpy CapEx is a bit further out? And I guess a question associated with that, are there any implications with the hedge book? What's the current view on that?

Brendan Harris
CEO and Managing Director, Sandfire Resources

Yeah. No, it's a great question, Levi. And I do love it because Megan and I talked about it. As you know in this game, you achieve one thing. The question is very quickly, "But I want more. What next?

Levi Spry
Mining Analyst, UBS

Definitely. Yep.

Brendan Harris
CEO and Managing Director, Sandfire Resources

And rightly so. Rightly so. So the way we think about it and I'll pass to Megan for some of the minutia, but we are comfortable with our debt facilities in general. Facility A was the one that created some degree of constraint. And so for us, prima facie, really what the next step for us is thinking through with this new revolver facility, what's a longer-term solution that even further helps us with tenor and other features. So that's probably a next step for us naturally. We'll get to work on that pretty quickly because, again, it's just a natural step for us to take as a growing global copper producer. Beyond that, maybe, Megan, see if there's anything else with the specifics, hedge book, etc.

Megan Jansen
CFO, Sandfire Resources

Yeah. Just the specifics. No implications on the hedge book, Levi. There's no change. There's no additional requirements to hedge more tonnes into the future. That remains as is.

Brendan Harris
CEO and Managing Director, Sandfire Resources

Is that right?

Levi Spry
Mining Analyst, UBS

Okay. Yep. Yeah. It's good. Thank you.

Brendan Harris
CEO and Managing Director, Sandfire Resources

Thank you.

Operator

Thank you. Your next question comes from Ben Lyons from Jarden. Please go ahead.

Ben Lyons
Director of Equity Research, Jarden

Thanks. Good morning, Brendan, Megan, Jason. Just two questions from me, please. Firstly, just might dive into the accounts, please. Apologies for the detail. But obviously, a result that was very much in line up to the EBITDA line given your excellent disclosure in the quarterlies. But a bit of variation in that net interest expense bucket. And obviously, there's a lot going on in that note to the accounts with some FX losses and unwinding of discounts and facility fees and charges, etc., which are pretty unforecastable in nature. So maybe just to help us going forward, probably one for you, Megan. Just confirming that the new facility, the revolver we're talking about, is going to be U.S. dollar denominated. The Motheo facility is going to be U.S. dollar denominated. So probably little expectation for FX variances in that bucket going forward. Is that a fair assumption?

Megan Jansen
CFO, Sandfire Resources

Yeah. Thanks for the questions. Fair assumption, U.S. denominated debt across the board. We won't see any FX arising on that debt, Ben.

Brendan Harris
CEO and Managing Director, Sandfire Resources

But I think the thing to think about with that, Ben, is the way you have broader monetary items. So you've got receivables, payables, and other items that will always have some FX differences. So those elements do play through as well.

Ben Lyons
Director of Equity Research, Jarden

Yep. Yep. Okay. Cool. Thank you. And then maybe just a second one actually on exploration and acknowledging I think you mentioned that Richard's in transit. So firstly, on the accounts, again, looks like you spent about $10 million on exploration during the first half, well below the run rate. I think we're looking for $32 million for the full year from memory. So just wondering if we're going to see a material step up or possibly come in below that guidance. And the second part to that would be, again, just from memory, I think we're expecting some results from Black Butte around about now. And I might have missed it in the release, but just wondering if there's any comments you can make about that recent drilling program. Thank you.

Brendan Harris
CEO and Managing Director, Sandfire Resources

Yeah. Good one, Ben. Thank you. Look, you're right. If you look at the exploration expense, you'll see the very big delta, of course. Right up front was Australia. I've spoken about that. We took a very difficult decision to basically restructure and shut down the very vast majority of exploration activity here in Australia. It's not because we don't see Australia as being prospective or a place that we want to operate potentially in the very long term. But we've just invested considerable amounts of shareholder funds into very modern processing hubs in both Spain and Botswana. So our focus has to be in those regions. That's the permanent shift that you'll see until we obviously strategically take a different direction, which I wouldn't expect to happen anytime soon. Beyond that, it's really timing. Black Butte, and I'll pass to Jason to talk about the program.

But we've really kicked off an additional drilling program in literally recent weeks that is targeting the high-grade, deeper zone at Johnny Lee, which is a very promising area. It's really where the juice exists, if you like, in terms of getting your IRR out of your project. And we certainly need to see Johnny Lee as a standalone project, notwithstanding the permitting issues, being a high-teens IRR, low 20% IRR project for us to really get excited about it. So that's what we're focused on there. So you'll see that spend coming through. And remember, at both Motheo and in the Iberian Pyrite Belt, i.e., around MATSA, we very much focused regionally on our AGG surveys. So that's to airborne gravity, get that very deep understanding of the geological setting and help us become much more focused in our regional targeting.

Now, what obviously transpires into this half, we are back drilling at A1. And so with A1, we are focused on opening up, if you like, the known mineralization that was identified in phase one. What we're hoping in phase two will be able to come to the market somewhere in the current half with a maiden resource. We're going to, and we've just commenced, actually drilling at A4, testing the open-ended extensions. So you'll see that drilling coming through. And then we're going to get to T3, where we've identified additional opportunities in the footwall. And so you'll see that timing coming through. As well as, again, on completion of some of these basin-scale targeting activities, we should start to see a slight uptick in more regional exploration, i.e., not within the sort of footprint that we would consider relevant for the two processing hubs in Spain and Botswana.

Maybe, Jason, if you can just talk to Black Butte specifically and what we're doing there at the minute.

Jason Grace
COO, Sandfire Resources

All right. So in terms of Black Butte, we have commenced the drilling program there. We started that. We mobilized drill rigs there just before Christmas and got into drilling early January. We've completed four holes of that program, and we're in progress on a fifth. We don't have any assays coming through. But we are processing that core at the moment, and we expect to be able to disclose or report some of these results in coming weeks or months there as well, depending on those turnaround times. As Brendan said, we are targeting the higher-grade, lower copper zone at Johnny Lee.

We're particularly looking at near-mine design extensions to that mineralization, which is a very prospective zone for us with the view that any potential ore that we identify from that could come into the feasibility of mining schedule early in mine life and significantly add value to the financials of this project as well. We're quite optimistic.

Brendan Harris
CEO and Managing Director, Sandfire Resources

So thanks, Ben. Appreciate the questions. Look, just I guess to yourself, but anyone else, of course. Ben Crowley, head of IR, is ready to answer questions on the accounts, particularly things like the underlying earnings adjustments, the FX differences that you've referred to. So please don't hesitate to get in touch with Ben. Did you have anything further, Ben?

Ben Lyons
Director of Equity Research, Jarden

No, no. That's all from me. And yeah, apologies for going into the weeds on the call.

Brendan Harris
CEO and Managing Director, Sandfire Resources

No, that's more than happy. Thanks, Ben.

Operator

Thank you. Your next question comes from Matt Chalmers from Bank of America Securities. Please go ahead.

Matt Chalmers
Research Analyst, Bank of America Securities

Good day, Brendan, Megan. Megan, probably a question more for yourself. I know it is kind of accounts-related but a bit more high-level. If we look at the group asset base and the depreciation at MATSA year-over-year versus the broader group CapEx spend, can you give us some thoughts as to the kind of longer-term strategy to maintain the value of the operating base? Kind of looking on our numbers, it's roughly kind of a $150 million-$200 million delta each year between the CapEx and the depreciation rate, so just for the operations to stand still for the next couple of years. Does it really just come down to kind of mine life extension to lower the units of depreciation or appreciate any perspectives you have on that?

Megan Jansen
CFO, Sandfire Resources

Thanks for the question, Matt. Absolutely, the life of mine extension is an important area that will, in time, see that depreciation level reduce for MATSA. Hence, that's a critical component of our strategy and something the team is actively focused on delivering over the next few years. Brendan, did you want to add anything onto that?

Brendan Harris
CEO and Managing Director, Sandfire Resources

Yeah. Look, I think you're spot on. We've said that the first thing we need to do is deliver the growth at Motheo and improve the consistency and predictability of MATSA. I think we've shown that we're making inroads there. Operationally, I think a good period for us. MATSA are obviously delivering record throughput rates at 4.6. The processing facility is actually running at a similar clip, which we haven't done before. And then with Motheo, of course, the ramp-up's been particularly good. But from here, it's really all about increasing reserves and resources. And I've talked on many calls and to many of you in the past that it's a rough rule of thumb for me. And what we talk about here is we've got to get towards 15 years of reserves in front of our processing facilities and aim to do that in three to five years.

Easier said than done, of course. You always need a little bit of luck in life. But really, it's about hard work and planning. It's really about chasing up the work that's already identified, these areas such as San Pedro and Olivo at MATSA and particularly the geophysical anomalies, the conductors that have been identified at depth below MATSA 2, so down dip of Magdalena. They're big, big opportunities for us. And then in the longer term, it's the concept study that relates to Sotiel and what that could mean in terms of the way we can reconfigure the entire operation. All of those things will be helpful. Now, depending on the success, of course, that might lead to additional capital from time to time.

And if that is the case, i.e., to get out to some of these areas that really open up value, we need to be able to justify that to our shareholders. We will certainly do so. Beyond that, at Motheo, if you think about what I mentioned earlier, A1 maiden resource, hopefully a T3 extension of some sort. A4, we're hopeful of an extension there. We already have sort of nine to 10 years. That sort of work programme starts pushing you up towards that targeted area, we hope. Time will tell. But then it's really to Richard and the team and the work that's being done to understand the depositional environment of these sedimentary copper deposits, but more importantly, the geological structures and so on that are really, if you like, delivering the enriched copper areas. The work that's underway on that is very promising.

Again, multi-year work programs in both areas. But our geologists couldn't be more excited than they are today.

Matt Chalmers
Research Analyst, Bank of America Securities

Yeah. Thanks, Brendan. Look, I think just touching further on your point around MATSA. So I mean, is it safe to say that where we stand today, there's more value potential around the exploration and greenfield in the Iberian Pyrite Belt? Or do you feel there's enough juice left in some of the other existing operations in close proximity to MATSA where it would make potential sense to roll them up into the fold?

Brendan Harris
CEO and Managing Director, Sandfire Resources

Awesome. Look, first and foremost, I'd say the most significant potential is actually within our mineralized systems that we currently control and are in. If you look at San Pedro, it's within 150 meters-200 meters of the existing mineralized zones. Limited development to get out there. It's shallow. So it's not only going to bring significant tons, it's going to give us cost advantages, opens up more mining areas, which should help us with productivity. It's all of those things. Olivo is very much the same. And as I said, the down dip conductor will do exactly that. There are also other ore bodies in very close proximity that are in other hands that we're wanting to understand. And I'm talking within 5 km and 10 km that sit within private hands.

We want to understand what the potential is there because we are the logical party to help bring those into future production. They're large mineralized systems. And so again, good potential for us to explore those in a very, very capital-efficient way. And that's really the focus for us. And then Motheo, again, we control the very large majority of the Kalahari Copper Belt. So we've got more than enough land to keep ourselves busy beyond what I've disclosed already. But Jason, I don't know if there's anything to add to that?

Jason Grace
COO, Sandfire Resources

Look, and you might kick me under the table, Brendan, coming back to Ben's point there and being under budget for this year or not spending a lot, I've offered to help Richard and spend any money that he's not going to spend this year because we have a lot of potential in and around both Magdalena and Aguas Teñidas. I'm very keen on getting drill holes into the T3 footwall zone. I think all of those things will give us growth in terms of resources and reserves, without a doubt.

Brendan Harris
CEO and Managing Director, Sandfire Resources

Yeah. And so again, I just want to stress, of course, we look and want to understand what's out there. But we have more than enough sitting within the portfolio to keep ourselves busy. And we think we have all of the opportunity to unlock a lot of value for shareholders. And we actually think that's going to be the most capital-efficient way that we can focus our efforts as well. So nothing's changed with that.

Matt Chalmers
Research Analyst, Bank of America Securities

Yeah. No, it makes sense. Thanks very much. That's all from me.

Operator

Thank you. Once again, if you wish to ask a question, please press star one on your telephone. We'll now pause a moment to allow for any final questions. There are no further questions. I'll now hand back to Mr. Harris for closing remarks.

Brendan Harris
CEO and Managing Director, Sandfire Resources

Look, thanks, everyone. Again, I just want to thank my team and the broader organization. I think the company operationally had obviously a very safe half and a very successful half with MATSA hitting record throughput rates, Motheo really hitting its straps. Our job is to keep delivering. We're working hard. We look forward to catching up with you next time. Thanks for your interest and have a great day.

Operator

Thank you. That does conclude our conference for today. Thank you for participating. You may now disconnect.
