Thank you for standing by, and welcome to the Sandfire Resources March 2023 Quarterly Results. 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 one on your telephone keypad. I would now like to hand the conference over to Mr. Ben Crowley, Head of Investor Relations. Please go ahead.
Good afternoon, everyone. Thank you for joining us today on the call to discuss our March 2023 quarter. It's my pleasure today to introduce for the first time, Sandfire's new Managing Director and CEO, Mr. Brendan Harris. Also speaking on today's call will be Jason Grace, our Chief Operating Officer, and Matt Fitzgerald, our Chief Financial Officer. Also in the room for Q&A, we have Richard Holmes, Executive of Growth, and David Wilson, our Head of Technical Services. Without further ado, I will hand over to Brendan.
Thanks, Ben, hello and good morning from here in Perth. My name is Brendan Harris, and I'd like to welcome you to our third quarter conference call, my first as CEO. As Ben said, I'm joined by Jason Grace, our Chief Operating Officer, and Matt Fitzgerald, our Chief Financial Officer. Before we dig more deeply into the results we provided today, I'd like to make particular mention of Jason. It's never easy leading in an acting capacity, and I'm sure you'd all agree he has done an exemplary job. Thanks, Jason. I'm really looking forward to achieving great things with you and the broader team. In my first four weeks, I'm pleased to say that I've been particularly impressed by the energy and enthusiasm of our people, the passion they have for Sandfire and our industry.
I've also had the opportunity to visit our MATSA mining complex in Spain, and was left with a very positive impression of the embedded potential that exists within both the geology and our installed infrastructure. I'm obviously excited to be visiting Motheo in the second week of May, in no small part because Jason assures me copper concentrate will be on the ground. No pressure, Jason. Turning to the formalities of today's call, I'd like to remind you of the various disclaimers that accompany our quarterly materials and the notes we've provided to help better understand our disclosures. I should also note we are trying something a little different today, responding to your feedback. Ben Crowley tells us you'd like less time spent on introductory remarks and more time for Q&A. We won't be doing a page turn.
Jason, Matt, and I will touch on the critical drivers of our business in around 15 minutes before turning to an extended Q&A discussion. We welcome all feedback following the call, as we'd like to use these sessions to focus on your areas of interest. So why Sandfire and why now? Well, as a company, we've established a unique and solid foundation from which to grow. We're playing in the right place at the right time as an emerging global copper producer of significance. Of course, safety and broader risk management will always be at the core, and while I'm not one to celebrate safety outcomes, as we can ill afford to take our eye off the ball, it would be remiss of me not to mention the record low risk of 1.8 achieved in the quarter.
From a broader risk management perspective, we cannot overstate the importance of the new agreements that have secured attractive fixed-price, carbon emission-free power supply for MATSA. These agreements substantially reduce massive exposure to the spot market, particularly from CY 2024, and Matt will talk to this shortly. From a production perspective, we've given greater prominence to copper equivalent metrics. While we will continue to provide all of the component parts so you can test and probe all aspects of performance, we feel it is important for us to communicate in a way that reflects how we think about value when making critical decisions running our polymetallic mines. Jason will provide a fulsome update on production shortly. What's happening right now? Well, as I touched on earlier, we expect first concentrate at Motheo in the coming days in what will be an increasingly important milestone for our company.
In parallel, we are fast-tracking the embedded low-cost expansion to 5.2 million tons per annum to deliver contained copper production of around 50,000 tons per annum from Motheo around the end of CY 2024. We're also excited about the recent discovery at San Pedro. I won't steal Jason's thunder, but I can confirm I was lucky enough to eyeball core samples from our latest step-out hole on my recent visit. With that, I'll hand over to Jason.
Thank you very much, Brendan. If we look at operations and projects for the March quarter, and starting with MATSA. Mining continued across all three mines with the Aguas Teñidas and Sotiel mines delivering production rates that either met or slightly exceeded expectations. At Magdalena, and as previously indicated, high-grade cupriferous ore from the Masa 2 East section of the mine was accessed during the March quarter, albeit at a slower production rate deliberately designed to manage stope stability and minimize dilution. While we saw an improvement in overall mining rates achieved at Magdalena during the period when compared with the December quarter, productivity rates remained approximately 15% below plan and included some additional polymetallic ore from the Masa 2 Central and the Masa 2 West areas of the mine.
The lower mine production rate from Magdalena in turn constrained ore processing throughput and resulted in lower copper metal production than planned with zinc, lead, and silver production exceeding expectations. Operationally, we also saw further benefits of mining at this slower rate in the Masa 2 East area. This delivered more stability in the mine plan and a more predictable blend for ore processing, which in turn facilitated an increase in copper metallurgical recoveries during the quarter. Looking forward to the fourth quarter and full year, we will continue with this operating strategy at Magdalena. This is forecast to increase the proportion of polymetallic ore being extracted, producing lower annual copper production and offset by higher levels of zinc, lead, and silver. Is forecast to deliver combined metal production within 1.4% of guidance on a copper-equivalent basis.
In line, we are providing updated financial year 2023 production guidance from MATSA of approximately 98,000 tons of copper equivalent tons, with lower copper production at approximately 56,000 tons, largely offset by higher zinc at 86,000 tons, lead at 9,000 tons, and silver production at approximately 2.6 million oz . Moving now to group production. At the DeGrussa operations successfully transitioned to processing of oxide copper stockpiles in mid-February after completing processing of transitional ore and mineralized waste stockpiles. Processing of oxide stockpiles is based on utilizing the existing DeGrussa flotation plant with minimal circuit changes and adopting a simplistic approach to treat stockpiles with oxide flotation reagents. Production for the March quarter was 4,396 tons of copper and 5,111 oz of gold contained.
Whilst we expect processing to continue into the June quarter, no formal production guidance is provided beyond the 28,000 tons of copper production currently projected for the year. At Motheo, we're very excited that first concentrate production is anticipated to occur within days, and our first concentrate shipment is now scheduled for the middle of the calendar year. Construction activities are now very close to completion, with several key milestones achieved during the quarter. Included, first ore mined from the T3 Open Pit was delivered to the Motheo ROM pad with over half a million tons of ore now stockpiled. The primary crusher and coarse ore stockpile handling system has been commissioned and is now fully operational.
A SAG mill erection is now complete, with the variable speed drive and motor partially commissioned, and the operations team are at full strength and more than ready to take control of the site. Based on the combined outlook for all operations, group production guidance for the year has been refined to approximately 87,000 tons of copper, approximately 86,000 tons of zinc, 9,000 tons of lead, 20,000 oz of gold, and approximately 2.8 million oz of silver for total copper equivalent production of approximately 134,000 tons contained. Finally, as Brendan mentioned earlier, we're all very excited about Sandfire's recent discovery at MATSA. On the 24th of January this year, Sandfire announced to the market that underground drilling at MATSA had identified a new zone of volcanic massive sulfide mineralization, which we call the San Pedro zone.
San Pedro is directly adjacent to the Aguas Teñidas mine, with very encouraging widths and grades of mineralization ex-intersected to date. This zone was discovered following a full geological reinterpretation of the Aguas Teñidas geology by the MATSA team. This represents the first significant exploration breakthrough under Sandfire's ownership. Initial step-out and close-space drilling, infill drilling, has defined a strike length already of over 400 m in extent, with step-out drilling approximately 100 m to the west recently completed. As Brendan touched on previously, we were fortunate enough to be able to see this drill core on a recent visit to MATSA. We're absolutely delighted to see the extent and tenor of the intersected massive sulfide mineralization.
Looking out beyond the initial San Pedro discovery, probably more importantly, the MATSA team, through their excellent work, have also identified a further two-kilometer strike length of this untested prospective horizon. I will now hand over to Matt.
Thanks, Jason. Metal production drove lower revenue of $163 million for the quarter and $595 million year-to-date, with over 70% of revenue coming from 62,000 tons of payable copper from MATSA and DeGrussa, and 20% from 50,000 tons of payable zinc at MATSA. Year-to-date operations EBITDA has risen to $243 million at a 41% operations EBITDA margin, with MATSA contributing $157 million and group EBITDA of $190 million. While MATSA sells its concentrates effectively on a daily basis, DeGrussa saw a build in highly marketable copper concentrate stocks with around 6,000 tons of payable copper available for sale in the June quarter, with concentrate from oxide processing running at around 35% copper. This impacted March quarter group revenue, EBITDA and cash holdings.
We also expect the final one or two DeGrussa high-grade concentrate sales to occur into the September quarter, impacting cash and working capital at 30 June. Operating costs have stabilized and reduced across mining and processing as energy prices are pleasingly settling towards historical levels as guided, following their peak in the first half of the financial year. We are seeing the impact in terms of price of new long-term power supply agreements. Higher TC/RCs came into effect this quarter in line with movements in global benchmarks. Operating cash flows at MATSA at $65 million for the quarter reflected the EBITDA result. MATSA completed its scheduled $80 million debt repayment in January, following the $118 million repayment in September last year, while continuing to invest heavily in mine development across the three months.
As previously flagged, following the Ore Reserve extension achieved mid last year at MATSA, we're progressing a resculpting and rescheduling of the remaining $452 million MATSA debt facility to assist the generation of working capital and smooth the remaining schedule across a now much less restrictive Ore Reserve tail within a significant overall Mineral Resource. Amendments are progressing well through credit and documentation review processes. In C1 terms, lower than planned copper production impacted unit costs. However, with the scheduled high copper and zinc production in the June quarter, we are expecting C1 unit costs at MATSA to move to around $1.50 per pound. Full year C1 guidance at MATSA is largely flat overall, with lower copper guidance offset by higher zinc, driving higher by-product credits.
Q4 production at DeGrussa has seen further copper production to April. However, any largely unguided production in May and into June will be at a higher C1 cost and lower margin, say around 10%-15% at $4 copper due to the processing of the final lower grade and lower expected recovery stockpiles during this time. Production is scheduled to end at DeGrussa in the second half of the June quarter, with a formal sales process for DeGrussa progressing in parallel. At our new copper mine, Motheo in Botswana, we drew down the final $30 million tranche of the total $140 million, 3.2 million ton per annum T3 debt facility with Société Générale and Nedbank.
Ahead of now progressing formal discussions around the planned $200 million uplifted facility, which funds the planned A4 expansion to 5.2 million ton per annum processing rate, along with operating cash flows from T3. Closing group cash was $177 million at the end of the quarter, with net debt of $415 million. We expect group net debt to reduce with the generation of positive cash flow from MATSA and then Motheo, we'll also see the initial impact of any uplifting facility at Motheo contributing to A4 expansion capital. In that regard, we look forward to updating the market on the key capital management activities over the coming weeks across both MATSA, Motheo and also DeGrussa, as we continue our balance sheet transition focused on supporting our growth strategy.
Thanks, Matt. The work you and the team are doing on the balance sheet is clearly a key enabler of our business. Before we move to Q&A, I'd like to leave you with this. We're primed to deliver 25% growth in copper equivalent production in the three years to FY 2025. To get there, we've defined our immediate priorities. Maintain momentum in safety performance. Nothing is more important. Establish a credible pathway to reduce our carbon emissions. Lock in solar energy supply for MATSA, the last pillar in our power supply negotiations. Advance underground development and general ore body knowledge at MATSA, and optimize our planning processes to minimize dilution and increase recoveries with a focus on value over throughput.
Of course, it goes without saying, we must deliver the strong increase in production plan for the fourth quarter, ramp up Motheo safely and sustainably, and work to quickly understand the extent of San Pedro mineralization that lies at a relatively shallow depth within 100 m of Aguas Teñidas. While we'll sharpen our focus on the basics, as that's our ticket to the game, it's our growing understanding of the geology that gets me particularly excited. With that, can we please have the first question? Thank you.
Thank you. If you wish to ask a question, please press star one on your telephone and wait for your name to be announced. If you wish to cancel your request, please press star two. If your phone, please pick up the handset to ask your question. Your first question comes from Hayden Bairstow with Macquarie. Please go ahead.
Hey, morning, guys, and welcome aboard, Brendan. Just a couple more from me. Firstly, on MATSA, it might be a question for Grace just based on, from the site too. I just came to better understand what's actually going on at Magdalena and how quickly you think you can resolve it, or is there gonna be a total need for redesigning of stopes to make sure you can get, you know, more stable ground conditions to get that ultimate production rate up towards that sort of, you know, close to 2.5?
Yeah, look, Hayden, I'll throw to Jason. If I can just make a couple of very quick observations. You know, again, first and foremost, I guess I can come at this with fresh eyes. Having gone underground at Magdalena only a couple of weeks ago, you know, you can see that we're operating in and around the shear zone. We don't, you know, hide from that. What you can also see, though, is that the team is doing a very good job in the circumstances. Remember, when we inherited this mine, there was very little geotechnical understanding and modeling. To some extent, it has meant the teams at times are flying a little blind. That is changing and changing rapidly because you've heard us talk about the geological reinterpretation work that's being done.
That also translates to a heavy amount of work going on to remodel and understand the geotechnical characteristics of the ore body. That combined with the focus that we now have on every aspect of our mine planning, I think sets us up well. Again, we're not gonna rush to try and drive throughput to 4.7 million tons. We'll get there. In fact, the weekend prior to my arrival on site, the team was actually running across a weekend at 4.8 million tons per annum throughput rates in the plant. We know the plant can do it, but it's a matter of driving it at the right time in a way that's reducing that dilution effect. Obviously, as we said, maximizing recoveries, and that's built into our plan because ultimately that's gonna value, as we said, the value of the resource.
Jason, over to you.
Absolutely. Really to reiterate that, you know, that Hayden, we've been talking about this for a while. The ore body knowledge that we had that we inherited there at MATSA was really very, very basic. For us to be more predictive and have control and stability around, particularly around delivery of our mine plan, we need to complete that work. Now, largely, we're well advanced, but certainly we've had this plan now for a period of time where we expect to have that full knowledge starting to come into mine plans around, you know, late 2024, so probably about another 12 months. One of the things you're seeing, and coming back to your comment there about, you know, do we need to redesign Magdalena? The answer to that is no.
What we do need to do is run certain areas which are affected by particularly structures and stability. We need to run them a bit slower, so we're making sure we're not wasting the ore body, we're not over-diluting it, and we're not trying to push a bad position in terms of the production schedule. To do that, we need to build up our developed stocks. We've been working on that for a while, but we will see that once again kick in towards the end of next year. The approach that we've been taking, as Brendan said, is about, if you like, just reacting to the ore body and what we're seeing, getting stability into that mine plan and compliance.
What that allows us to do is actually present a consistent or a predictable blend going to the processing plant and really deliver upside there on improved recovery and overall performance in the plant, which will deliver us better value and better metal production as well.
Hayden, sorry, I might just add. What we don't want people to take away from that is that therefore as we look to next year, you know, we've got significant concerns. You know, we haven't provided updated guidance verified 2024 today because we are working through our planning processes, and the team's, I think, doing some really good work there. What I can tell you is, the preliminary estimates with, you know, I guess, a slightly moderated approach to throughput, we are still seeing the same sorts of level of equivalent metal production, as was previously indicated, albeit with copper incrementally higher than what we're expecting to see this year. Hopefully that helps.
Yeah, terrific. Brendan, just I want I know it's early days, but are you sort of planning on another full year result or later this year to sort of put a sort of more strategic outlook for what you're thinking in terms of Sandfire? It's obviously the two core assets and both will be in production by then. You obviously still got a fair bit of debt to deal with. Do you think you'll be in a position later this year, or is the focus really just around getting these operations humming and getting that debt level down?
Yeah, look, I guess I go back to prior experience, you know. In a past life, as you know, I was involved in the formation of a very large company from nothing on day one. I think we learned, you know, firmly in that process that there's value in sitting back, listening, observing, and making sure you understand your context, but then coming out with real intent. So for me, you know, I'm very much getting around the grounds, if you like. Been to MATSA. I'll get to Motheo, as I said, in a couple of weeks' time. I'm gonna meet with a number of the analysts and obviously a number of investors.
It's bringing all that together to make sure again that I've got the full context, particularly, as I said, hearing from our people what's working well, where they see the opportunities for improvement and build that in. You know, I would say, however, you know, again, we've got a fantastic growth pipeline. You know, it's organic, it's there. The most important thing for us is to deliver on that in the way that we've outlined. We haven't talked a lot about Black Butte as well. You know, I think you're gonna start hearing us talk more about that over the coming 12 months - 18 months. Permitting is, you know, and has been a challenge, but we think we're starting to get some, if you like, we'll see some light at the end of the tunnel there. It is very hard to find copper units.
It is very hard to buy them in the environment today for value. When you've got them, make sure you understand them and make sure you optimize those resources to the maximum extent possible. We do need to understand Black Butte. I think there's a substantial opportunity there for us to create value. Again, I look forward to talking about that more in the future. I mean, Jason was just in Black Butte. I might just very quickly pass to him and see if there's any observations he wants to make.
Yeah. Look, Hayden, as you know, I had a great trip over there. It was about three weeks ago, the week before Brendan arrived. And that was deliberate. It was about getting an update on where that project is, getting an update on thinking from the team over there. I'll walk away. I've always been a believer in this project, but certainly this solidified my belief in the potential over there. I do believe we have a pathway to production over there, but we do need to do some more work to be able to get there. Certainly very excited.
Okay, great. Thanks, guys.
Thanks, Hayden.
Thank you. Your next question comes from Rahul Anand with Morgan Stanley. Please go ahead.
Hi, team. Thanks for the call, Brendan. Welcome and best wishes for the new opportunity. I've got two questions. First one's on MATSA. Just wanted to get some clarity. I mean, you've. It's basically a follow-up to Hayden's. I mean, I wanna get my head around sort of where we can expect the throughput rates to be. I mean, is 4.4 the right number to be thinking about future throughput rates as you try to target that reserve grade and you also try to improve recoveries and dilution? As a follow-on, I mean, that 5 million ton per annum target.
Is that not really something that you're gonna be focused on to begin with, and you're just basically gonna try to maximize the ore body value just by looking at that reserve grade and 4.7? That's the first one. I'll come back with the second. Thanks.
Okay. Look, great questions, and thanks, Rahul, for the earlier remarks as well. First and foremost, let's be really clear. We see right now the value in actually focusing on recoveries, but particularly managing dilution to make sure we get the best value from those resources via the metal equivalent production we achieve. In the near term, you know, if you look in recent times, 4.4 million tons-4.5 million tons is a good number. Let's be really clear, as I said, only weeks ago, the plant was running at 4.8, so it will be variable depending on where we are in the mine plan.
I can assure you that as soon as we start to see the levels of recovery that we've built into next year's plan and are being refined, and we're starting to see, again, this geotechnical knowledge come through, our absolute objective is to, as quickly as we can and as safely as we can, but most importantly, as sustainably as we can, is to drive to 4.7 million tons per annum. That's just on that one. I think with regards to the 5.2 million tons in respect of Motheo, it's really important to realize that the way that that plant's been developed, which is quite unique, the team's actually been building a 3.2 or nominal 3.2 million ton per annum project, knowing that we're moving quickly to 5.2 million tons.
Much of the plant has been designed at a 5.2 million ton per annum rate. In effect, the largest component we need is the ball mill to go to 5.2 million tons per annum, and that work is being run in parallel. Again, we think that's gonna deliver us a very rapid and low-cost expansion. Raul, did that cover off on your questions?
Yes. Yes, it did. I mean, my 5 million ton reference was basically in the outer years, I think, at the start when the asset was acquired, that's MATSA. It was talked about a potential run rate that would be, you know, the top of the mine plan, you know, mines performing perfectly, plant performing perfectly. So that was sort of my question.
Yeah.
Look, I understand you're probably focusing on that 4.7 first up, but if you wanna add anything to that, I'd love a bit more color.
Yeah, apologies. I heard the 5.2, so my mistake. Look, it is a good question, as I said. Again, get stability, get consistency, get the recoveries, drive to 4.7, and then continue to creep. I mean, you're never gonna stand still. This is an industry where you have to drive continual improvement. You know, I don't think we're here to say there's any change in that, but again, I think the critical thing for us is we've got to prove our ability to deliver on these numbers. That starts with the fourth quarter. There's a substantial uptick in production, which will not only drive revenues, it's gonna have a significant impact on costs. We need to achieve that so that you start getting the confidence that we believe you should have. Thanks, Rahul.
Okay, perfect. Just one quick follow-up on that, Brendan, if I may. On my numbers, it doesn't, but is this contingent on your debt restructuring plans, the ability to run at that lower run rate? I mean, you did specify that you're expecting similar or better copper production, but does that then impact zinc? Does your debt restructuring plan make this new mine plan contingent in a way?
No. No, not at all.
Okay.
What we expect is this new mine plan is just gonna deliver us better outcomes both, in terms of as Jason said, that predictability, but it's gonna flow through into the financials as well. You know, if you're producing similar levels, broadly the same levels of metal equivalent production at lower throughput rates, that's a good story. No, look, I think as Matt said, you know, and I've had quite a lot of, if you like, oversight of this as well, we're progressing very well with the conversations with the banks. We don't wanna go too far because, obviously you're never done till you're done. As Matt said, you know, the syndicate is working through credit approvals as we speak.
You know, we'll provide an update, again, as Matt said in the coming weeks. There's no linkage between these two things. You know, again, coming with fresh eyes, looking at what the team's doing, this is the right way to run the business for shareholder value. Again, don't think for one minute we're taking our eye off the ultimate prize, which is getting those throughput rates up, but, you know, with better underlying performance.
Understood. Okay. Thank you. I'll queue back in.
Thank you. Your next question comes from Paul Young with Goldman Sachs. Please go ahead.
Thanks. Hi, Brendan. Hi, Jason and team. Brendan, good to connect on the call. Interested in some of your further thoughts on MATSA, Brendan, seeing as, you know, it's clear lots of exploration upside, but, you know, the mine complex has sort of struggled to get consistently above 4.2 million ton run rate since the acquisition. I see you've left it, to your point, you've left FY 2024 and FY 2025 guidance unchanged. I'm just curious about the next sort of firm update on the medium-term mine plan. You're doing the geotech, you know, remodeling at the moment. When can we expect, you know, an update on the medium-term plan?
Yeah. Thanks, Paul. Look, we would expect, you know, having completed the annual cycle, to provide a full update in the fourth quarter report, particularly obviously when we get around the grounds and manage to see people and talk about results at the full year. You know, again, we look forward to that opportunity. Hopefully, as I indicated earlier. We're not seeing a shift in metal equivalent production relative to what we've talked about previously. Nothing material, albeit, as I said, you will likely see a lot of this slower, marginally slower throughput rate for that period. Paul, that's probably all I can add at this stage.
No, that's fine, Brendan. Switching over to Botswana and Motheo. Just far as, you know, you're just about to start up and produce first copper. As far as, you know, referencing the DFS and costs within that study, and, you know, where we sit, we all know there's been industry cost inflation. I think your last estimate life of mine for C1 costs is about $1.50/ pound. I guess the question is, you know, are you happy with that estimate, and, you know, or will you update the market also with the full year result?
Yeah, look, Jason's living and breathing the commissioning and ramp-up profile of Motheo, so maybe I'll throw to him to have the first shot.
Yeah, Paul. Look, from our point of view, we did provide an update there when we completed the 5.2 million ton per annum feasibility study, which is fairly recent. We've not seen a lot of movement in costs there in Botswana at this point in time, noting that there is fairly healthy inflation rates there occurring. It does impact our labor rates, but labor rates aren't, say, as high a proportion as they would be here in Australia. Overall, that $1.58 that we quoted on that C1 cost, at this point in time, that's the latest information we have.
As we start to go into production, we will be updating those costs, particularly for the fourth quarter and our estimates for next year, once we start to see particularly what the processing plant's doing over the next couple of months.
Yeah, Paul, I think one of the things for me, you know, we're obviously gonna need to watch and see how that progresses. Getting the tons is gonna be the critical piece, as you know. You know, for me, what I'm gonna be looking at most closely is everything that I've read and all of the study work, when it points to the mineralization, it being relatively coarse, and it should float well. You know, the team's very hopeful that it should be relatively uncomplicated, barring anything unforeseen, for us to ramp up this operation. Again, it's not metallurgically complex. You know, we will provide a further update, obviously, with the fourth quarter and then into the full year.
Yeah. Thanks, Brendan. Last one, just on slide 25, the, you know, the aerial sort of map of Motheo, and, yeah, just noticing obviously the Khoemacau copper project and, you know, the proximity to Motheo. I know you said that, you know, you've got a lot of organic growth and exploration upside at MATSA in, you know, back-buttoning your comments there actually. Saying it's been tough going. you know, I guess the question is that you've got a lot of work to do, and you've got to, you know, ramp up Motheo first and foremost. you know, I guess there's an opportunity there with potentially lots of synergies.
Maybe the question is that, you know, has this opportunity maybe come a little bit too soon, you know, for Sandfire based on where you're at?
Yeah, look, excellent question, Paul. You know, I knew it wouldn't be lost on you when you looked at the map that there is a party that sits obviously proximal to our Motheo operation. I think the first thing I'd say is, if you look at our land holding in the belt, we have a substantial land holding. We already, you know, have the majority, if you like, of that acreage. Our areas are relatively underexplored. We see significant potential there. As I said earlier, this is about, you know, establishing a strategic, strategically valuable production hub. On the flip side, as you know, again, you repeated, we have a wonderful organic growth pipeline.
The most important thing for shareholders is that we don't get distracted, and we deliver on our promises. We think through that, we'll obviously release substantial shareholder value. If the Khoemacau asset comes to the market as people are suggesting it will, of course, we need to look. Again, you know, I will never take my eye off shareholder value. I've always believed that M&A is a nice to have if it makes sense. It's never a have to have. Even more so when you've got a business like ours with such strong embedded growth potential. Again, will we have a look? Sure. Are there synergies? Potentially. Would it likely be a competitive process? Richard Holmes sitting here with me, I think he'd suggest it will be.
It's never, you know, a problem to go in and see what you can learn. I hope that's not too vague, Paul, but that's probably all I'll add at this stage.
No, that's useful. Thanks, Brendan. Next time.
Thank you. Your next question comes from Kaan Peker with RBC. Please go ahead.
Well, hi, Brendan, Jason, Matt, Ben, and team, congrats and welcome, Brendan. Just first questions on the power agreement at MATSA. I think previously there was indications that it would be backdated to the start of CY 2023, but it looks like on the presentation, it's talking about CY 2024 now. Just wanted to check if all that the power agreement covers MATSA's needs and how that solar piece fits in there. Thanks.
Yeah, great question, Kaan. Let me have a go at that, and the team can chip in as needed. When you think about this negotiation, as I mentioned earlier, an absolutely critical negotiation at that, there's limited spot availability of excess power in the market currently. When you look at CY 2023 and the agreements that are being put in place, there are a number of tranches. The first tranche, which is, call it, roughly 30% of the operations power requirements, covers CY 2023 at a fixed price that's actually obviously attractive and at a competitive level when we look at the current market rates. Another tranche that comes in CY 2024, and that gets you up to something close, rough numbers, around 60% of the operations power requirements.
Again, that's why from CY 2024, you've got much less exposure to the spot market. The final piece in the puzzle is this, the solar agreements that they're at an advanced stage, I might add. That would get you up to around 80% coverage, hopefully from around that CY 2024 period or through that time horizon. That's really what I wanted you to take away. You're absolutely right. The first tranche that is impacting and having an effect this year was backdated to the start of 2023. Why you're seeing costs going up is not because of power. If you look at the increments, you can see the benefit coming through, rather, obviously, lower production, but you also had a step up in treatment and refining charges. Does that help, Kaan?
Yeah, sure. Just a follow-up on the TCRC-
Oh, sorry, Kaan. Kaan, if I can. Just to, you know, I think stress. When you look at the component of energy in the numbers that we've talked about today, the cost base, it's down below 10% now as a proportion of cost. Really it emphasizes how we are absolutely now seeing that translate into an improvement in processing costs.
Yep, understood. Just to follow up on that TCRC, that's coming mainly from copper as far as I understand. I think the zinc charges are set just recently and from memory, Sandfire's TCRCs are all off annual benchmarks. Is that correct?
Yeah, that's correct, Kaan. It's mainly from copper, so it drives about 30% of an increase in the copper side and not much on the zinc side.
Cool, thanks. Just a second question. I know, we talked about the, quite at length, but just with on MATSA's throughput, I think maybe Jason mentioned it, but talked about increased development over the year, and possibly the alleged users kicking in towards the end of the year. You know, if everything goes to plan, is throughput rate at, I'll say, as a base case, expected to increase to 4.7 at the end of FY 2024?
Yeah, look, again, I don't think we wanna be drawn on that today. I get what, you know, you're trying to do is, you know, work out what to put in the cell in your model.
Sure.
Again, what I'm focused on is what the metal equivalent output is. To be brutally honest, I'd rather we get more metal at less throughput. That's why I don't really want to be drawn on that today. Of course, in time to get to that 4.7 number, we'll come out with more clarity as we approach the full year. The team is right in the middle of that annual planning cycle. Unashamedly, I'm four weeks in. You can imagine I wanna probe quite deeply beyond what I've had a chance to do today. Indeed, all going well, I'm hoping to spend a month in MATSA from mid-June into July. You know, again, we'll be well-placed to come back to you in due course.
Sure. Thanks. If I could squeeze one more in just on, the expansion to 5.2. I think over the last couple of quarters that A4 dewatering seems to have been pushed out. Does that need environmental approval? Thanks.
Look, environmental approvals are still on track. We've actually moved through a consultation period, and we're out for public comment at the moment. Everything, as we understand at the moment is largely on track. The dewatering, in terms of the timing on that, there hasn't been a lot of movement, but that won't slow us down at all.
Sure. Thanks. I'll pass it on. Appreciate it.
Thanks, Kaan.
Thank you. Your next question comes from Daniel Morgan with Barrenjoey. Please go ahead.
Hi, Brendan and team. First question just relates to Motheo. When do you expect to be exiting run rates of 3.2 million tons, Brendan, on phase I? Thank you.
We expect to be there in July.
Okay. Very clear. When you say there's gonna be a concentrate shipment mid-year, will it sneak in before 30 June? Is that the expectation or after? Or, I imagine that you won't have commercial production this fiscal year, so no earnings to come through. Is that assumption correct?
Yeah, look, I think at this stage, Matt's nodding. We have been a bit cute with the comment we've put on sales. It's, you know, we've played around with that. It intentionally says mid-year for good reason. There is a, you know, a reasonable probability that it slips into the next year. It's very hard for us to predict. It could get right down to the wire. In some respects, I think what we'd prefer is you assume it creeps into the next year and that there is obviously a building working capital. At the end of the day, we're obviously focused on the bigger prize.
Yep. Very, very sensible. Then further, I mean, Brendan, congratulations on the new role. You're new to the business. I'm just curious on, you know, what is your plan or ambition ultimately with the Sandfire platform? You know, what is the mandate that you sought and got from the board when you got hired? Thank you.
Yeah, thanks, Dan. It's a good way to ask the question, actually. Look, you know, I came in here on day one, and what I said to the team is I don't have a fundamental change mandate. The main reason for that is, as I engaged with the board and the management team in those early discussions, I could actually see very strong alignment. You know, this is a business, as I said, that is primed for growth. It's primed for growth in a commodity that the world, I think, is really only coming to grips with how much is gonna be required to decarbonize the global economy, obviously through the major electrification process that's underway. We have all of the right hallmarks here.
The critical thing for me is obviously getting to know our people, making sure we embed the right culture. I think we need to find a way to embrace the culture in Spain whilst making sure the things that we hold dear, those standard, core common systems and processes, are absolutely reflected there. The same goes for Botswana. As I said, then understanding what the potential is of Black Butte. The reality is, I love the fact that we operate polymetallic mines. As you know, the major basin, providing copper units in the world today is in South America, and many of those very large mines don't have large by-product credits.
If you can get the productivity rates out of your polymetallic mines, optimize those throughput rates, and then benefit from by-products, you're gonna be firmly entrenched again in the cost curve below that major slate of production. That, in the environment that I see playing out over the coming years, I think positions Sandfire particularly well. I mean, fundamentally, our objective is not about scale. It's about how we grow shareholder value. That's what I look forward to coming back and talking with you about when we meet at the full year. Thanks, Dan.
Paul Young asked a similar question earlier, but, you know, is M&A within the mandate you have? you know, obviously there's Khoemacau nearby, but more broadly, you know, could you set out what might be considered, what might not be? What is in, do you think, Sandfire's DNA to add value to any opportunities?
Look, I think it goes without saying that, you know, again, through delivering on the commitments we've made around MATSA, you know, that will increasingly build the confidence of our shareholders in our operating capability. You know, we have that unique ability to operate underground and obviously now with Botswana moving into an open pit setting. Proving that gives us a wonderful platform. I really don't like to get drawn on, you know, do you do M&A or don't you do M&A? Frankly, I'll be honest with you, I think shareholders expect us to do everything and anything to create and maximize shareholder value. Therefore, our job is to understand the landscape, both internally and externally, and make the right decisions. Obviously, we'll be judged in the fullness of time.
You know, again, you know, I wouldn't expect within Sandfire I'd take any different approach to that.
Okay. Thank you very much.
Thank you. Your next question comes from Ben Lyons with Jarden Securities. Please go ahead.
Thank you. Good day, Brendan. Welcome back. Very much looking forward to that catch up for a cup of tea that you flagged, so please add me to your list. Obviously regards also to Jason, Matt, Ben, and the broader team of course. Just a couple on MATSA from me, please. Firstly, just a little surprised that the SAG mill's not fully commissioned at this juncture. Yeah, it was looking pretty good there in early February, albeit I recognize that the commentary was struck at 31 March, and it's, you know, another four weeks gone by since then. Can you talk to any specific issues in commissioning that critical bit of kit, or is it pretty much online for commissioning as we speak?
Thanks, Ben. You're right. On, on our numbers and on our detailed schedules, we're about three and a half weeks behind where we had hoped to be, particularly at the start of the year. It doesn't relate particularly to anything in the SAG mill itself. SAG mill's looking good. The reason that we can't commission that is we're still completing construction on the flotation circuit. Basically, it is the last thing that needs to be completed, and everything else is either imminently ready or already completed.
The one thing that, one advantage that we've had is that we've been able to commission as we go through progressively, and we expect that to ramp up fairly quickly once we get, you know, somewhere for that SAG mill slurry to actually go to after it goes through that mill.
Awesome. Thanks very much, Jason. Appreciate that. Maybe just moving across to the ROM pad. You know, really pleasing to see that you've got almost a month of high-grade ore sitting on the ROM now, you know, 1.1% copper. Maybe a two-part question. Firstly, can you clarify if that 1.1% is total contained copper or recoverable copper? You know, obviously excluding those oxides which have never been re-considered recoverable. Then, the second part of the question would be on the commissioning strategy, whether you know, stack the mill and the float tanks with the low grade, the 0.6% ore, or you kind of blend it with the high grade, or you go straight for the high grade. Thank you.
I might start with that one, Ben. We have been crushing low-grade ore, we will be commissioning on low grade, basically all the way through May and at least part of the way through June on current plans. We expect to be basically starting to feed some of that high-grade material coming into, you know, late June and July. We expect as well to ramp up and further to the questions before, we expect throughput to ramp up very quickly. Like a Lycopodium that have been, it has been our EPCM contractor has built almost the exact same plant elsewhere in Africa. We have good benchmarks in terms of, ramp up schedules, commissioning and ramp up schedules on this, on this exact plant.
We expect that that will throughput will ramp up very quickly, and then it will come down to basically management of the grind and the float circuit to get recoveries up. We expect to be there pretty much in July. In terms of the copper grades on stockpile, they are total copper, right? We have estimated recoverable copper or acid-soluble copper in there as well. Overall, we are seeing that level of oxidation decrease very rapidly as we progress down through the ore body.
Excellent. Thanks very much, Jason. That's really helpful. Maybe just a final one on Bots. You've just gone through the wet season over there. You had the added complication of Cyclone Freddy, which was building the east coast of Africa at the same time. Just any observations you can make about what happened on the grounds, you know, versus your expectations for the wet season, whether you suffered any impact to site access, for example, or, you know, excess surface water or any complications with the TSF, et cetera. Thank you.
No, Ben. Look, overall, it's been really quite robust. Site access has been really good, so no issues whatsoever. There's a real advantage to having the A3 highway basically within 15 km of the site. No issues in terms of supply chain and supply routes. If we look at it, no issues around water around the site at all. What we did do was, particularly in March where we did see higher rainfall, it did slow down mine production slightly, right? Overall, we're seeing that even that mine production is quite robust.
Maybe, Ben, if I can, you know, I just wanna really take the opportunity to again reiterate the amazing job I think that the team's done. I've read a number of analyst reports today, I think a few have made mention of, you know, what almost a remarkable effort it is to deliver a project as they have within budget in the current climate. Firstly, I just wanted to acknowledge that. I think just sort of to the heart of your question, it I think we would have even been slightly ahead of where we are today, if not for one of those sort of teething issues that you have towards the end of a project, whereby, you know, some of the workforce, if you like, is not necessarily as motivated to complete if they don't have a job to go to.
I think the team responded to that very quickly because we started to see a slight drop-off in productivity rates, labor productivity rates in the project. They responded very quickly by putting in certain sort of milestone, you know, bonuses, et cetera. Nothing material, but actually to get people focused on the prize again to make sure we get to that first production. Whilst I don't think weather had an impact, there was, you know, arguably a labor productivity impact that just probably pushed us three or four weeks beyond where we actually hoped to be. You know, indeed we were hopeful only probably around one and a half months ago prior to mine's commencement, as I understand it, that we'd actually be talking about first pro-concentrate production in the quarterly.
Yep. No, got it. That's really helpful. Thank you very much, Brendan. I hope you enjoy embracing the culture in Spain and Botswana over coming weeks.
Thanks for that. Appreciate it, Ben.
Thank you. Your next question comes from David Radclyffe with Global Mining Research. Please go ahead.
Hi. Good morning, Brendan and team. Sorry to laboring the point here on MATSA capacity, I just want to ask the question a different way, giving you a fresh eyes, because we seem to be locked in here to the three current mines, which, obviously, you know, the issue here is that you've got a hungry mill. Looking forward and in the long term, are we really missing here a fourth mine, you know, either found or acquired? Would it make sense maybe to think about toll treating some of the regionals around, given that your plant might actually be better suited to them?
Look, that's, you know, really appreciated and I think, it wouldn't surprise you that the thread of your question is indeed something we talk a lot about here. That is the fact that, you know, I think many people think of MATSA as one mine. The reality is we have three mines with a centralized processing facility. With obviously Motheo coming on, we'll have four. You know, that gives me a lot of comfort because we all know that mining is inherently volatile. First and foremost, it gives us some, if you like, diversity in the portfolio, first and foremost.
To your point then, the real question for us, as we start to understand mineralization like San Pedro, as we test the down plunge extension of Magdalena, you know, too early to say, but the potential for an extension of high-grade copper. The question then is: What do you do with that 4.7 and possibly 5 million tons of throughput capacity? How do you feed that material into the mill to optimize value? It may be that the way that you want to run that facility, not only to maximize the met contained metal, but also to assist you with how you manage just that overall flow sheet, your reagents and your recoveries, it may change.
The question is: Well, what do you do with some of these other deposits and resources, things like Sotiel, which is clearly not running at an optimized rate? How does that play into a broader strategy? I don't wanna be drawn on that too much right now, but you're absolutely right that I think that is a critical question that we need to understand and particularly understand in the manner in which we could potentially unlock value that's hidden at the moment. You know, thank you for raising that. You know, it is on our obviously focus list. It's right in the crosshairs of where I think there could be value creation.
It's just too early because some of that depends on this geological knowledge that we've been talking about, understanding the mineralization potential. Yeah, great challenge for us.
All right, brilliant. Thanks, Brendan. I'll pass it on.
Thank you. Your next question comes from Lyndon Fagan with JP Morgan. Please go ahead.
Thanks very much, and congratulations, Brendan. Look, the first question I had was just a follow-up on, the depreciation at MATSA. I'm wondering if you're able to give any color yet on how to calculate cash tax and the depreciation we should be using as a tax shield versus the guided depreciation of $250 million. Thanks.
Thanks, Lyndon. I think as we've mentioned before, you're best to probably model it on an EBITDA minus CapEx basis for tax, for cash tax. Also the depreciation side, as you said, we've guided about $250 for the year. We're probably in that range we think as we get there. There may, depending on that, you know, the achievement of our targets in the June quarter, given the ore that we're accessing in there, that may be $250-$260 in the depreciation side. As I say, on the cash tax side, I think you're best to stick in EBITDA minus CapEx. We can add some more color to that as you, as you wish.
Easy done. Okay, thank you. The other one, maybe just to briefly touch on copper TCs. They have gone up a fair bit in the quarter. I'm just wondering if this is the new run rate going forward, or whether there was something unique about the quarter.
Yeah. Look, I don't think so. I think the reality is it's, you know, reflective, as we've said in the note of market rates. Unfortunately, given our size, we're unlikely to influence those. I don't know, Matt, if there's anyone who'd just like to add any additional color.
Yeah, Lyndon, David Wilson here. I guess the, our treatment and refining charges in our cost are largely driven by MATSA where the volume is in this quarter, and it's the MATSA off-take agreement's linked to the benchmark. You've probably seen during the quarter, the copper benchmark went from $65 and $6.5 to $88 and $8.8. That's likely to mean the shift in TCs. As someone mentioned in the earlier question, the zinc TCs being released early in this quarter, which will flow through our contract resets on a calendar year basis.
Okay. That's all I had. Thanks again.
Thanks, Lyndon.
Thank you. There are no further questions at this time. I'll now hand back to Mr. Harris for closing remarks.
Well, thanks, everyone. Really appreciate the questions and the challenges. As I said, we look forward to getting around and seeing as many of you as possible in the coming weeks and months. It's a pleasure to obviously be able to present the first quarterly as the CEO of Sandfire. You know, I'm incredibly excited about the potential. It's a marathon, not a sprint. We're gonna be working hard. Again, our objective is literally to see how much shareholder value we can extract from what I think is a very attractive asset portfolio. Thank you again, and have a good day.
That does conclude our conference for today. Thank you for participating. You may now disconnect.
