  • Operator

  • Thank you for standing by. This is the conference operator. Welcome to the Metals Acquisition Limited Q3 2024 conference call and webcast. (Operator Instructions)

  • I would now like to turn the conference over to Mick McMullen, CEO of Metals Acquisition Limited. Please go ahead.

  • Michael McMullen - Chief Executive Officer, Director

  • Thank you and thank you everyone for joining. I'll be presenting the slides today along with our CFO, Morne Engelbrecht. So this is our Q3 quarterly results presentation, and we'll also give a bit of an update on our exploration activities. As usual, we've got our disclaimer at the front that this presentation has been lodged on the ASX platform and you can read that at your leisure.

  • You know, I would characterize the quarter as another business-as-usual quarter, the team delivered a very strong result of just over 10,000 tons of copper at a head grade of 4% mills. I think after our very strong Q3, there were some questions around whether we could sustain that sort of 4%-plus head grade and the answer is yes.

  • C1 came in at the bottom end of the range. We'd recently guided to USD1.90 a pound, which is continuing a downward trend. Morne and I will talk about how we managed to arrive at that. We have a clear pathway to 50,000 tons plus of copper out of this mine here within the next couple of years. We again had a very strong EBITDA margin through the year about 50% and we convert about 77% of that margin to cash.

  • Post the recent equity raise, we've got pro forma liquidity of about USD226 million which is well over [AUD300 million]. Again, all numbers in this presentation are in US dollars unless we specifically call them out. But it is a very large liquidity position for a company of our size, provides us with a lot of optionality.

  • So I'd say it was a good quarter, another business-as-usual quarter. And you know, despite production being down slightly quarter on quarter, our C1 was also down, and we guided the market to being Q3 just with the sort of scheduling of the stopes down slightly. And then we expect Q4 to be the strongest quarter of the year for us actually.

  • We realized broadly the spot price, so prices went down a bit during the quarter-on-quarter periods, but we broadly get spot. And as I said, we expect Q4 to be our strongest quarter. Pardon me, we have a very strong liquidity position, as I said, we ended the quarter Q3 with about USD81 million of cash after paying off some debt.

  • We are again tracking towards the midpoint of guidance as we've guided people towards around that 40,500 tons of copper and again, copper grade is hanging in there strongly at around about 4%. On the exploration front, I'll talk about we've had some really good success here, QTS South Upper, but it continues to confirm some high-grade copper hits as well as some zinc. We are drilling out much of the inferred which allows us to incorporate that into our reserves and we've actually had some really good success in stepping out into Virgin country to really expand the resources.

  • We spent about USD2 million in Q3 on exploration. Our big capital projects, the vent project is well underway and that's integral to sort of getting our production up well over that 50,000 tons of copper level. And QTS South Upper to commence in Q4, well actually, it's commenced this morning where we took the first cut out of that take off drive to head towards that deposit. We invested just under USD13 million in capital projects. Again, we've guided the market to USD52 million for the year and we continue to trap sort of bang on where that number was.

  • And then post quarter, obviously, we raised AUD150 million in equity that delevered the balance sheet gives us a lot of flexibility to pursue strategic opportunities and also to retire that mezzanine debt.

  • I'm going to hand over to Morne, our CFO to talk about a couple of the financial slides and over to you.

  • Morne Engelbrecht - Chief Financial Officer

  • Thanks Mick. Good evening morning, everybody. I'll be taking you through as Mick said through this slide and then the next slide as well which covers the cash flow waterfall for the quarter and again in US dollars and a quick recap on the recent equity raise as well. And then I'll cover some productivity slides later on. Also please note that all these numbers are unaudited, and we have more detail in our operational financial performance noted in the quarterly report released today as well.

  • On slide 6. Overall, we have a very healthy pro forma liquidity as Mick mentioned as of 30 September for around $226 million, that's indicated there. This includes the most recent successful equity raise completed after the quarter end, which provided a boost to the [Mac] balance sheet of around AUD150 million, USD103 million before costs.

  • This position us in a position of strength and further boosted by the fact that we had an undrawn revolving facility of $25 million, onsold concentrate ready to be shipped, outstanding QP payments and also a successful listed investments and poly metals which total around USD17 million that contributed to that liquidity.

  • If we look at the operational corporate side of the quarter on quarter movement, there are a few key drivers there to keep in mind that impacted the cash flow for the quarter. Firstly, you will remember that in previous quarter we sold concentrated was ready for shipment after a material buildup of inventory, this means that more than 2,000 tons of copper was sold in the June quarter that shipped in the September quarter with all that cash flow recognized in the June quarter.

  • That's mean that around $25 million of cash was captured in the June quarter that would have otherwise been recognized in the September quarter. In saying that we still had a very healthy free cash flow from operations of around $30 million for Q3.

  • An important point to note is that we have now also largely worked through that backlog of concentrate that we spoke about in the previous quarter. With the closing volume of unsold concentrate representing about USD9 million as of 30 September, which is in line with where we saw it reducing to by the end of this quarter. So for the December quarter, we would expect again that the copper tons sold should be in the same ballpark as the tons produced for the quarter, all things being equal.

  • Secondly, we further reduced our senior debt by another $8.1 million over the quarter. With our senior facility now sitting around USD166 million down another 5% over the quarter. And then with the equity raise, we also have a pro forma net gearing ratio, 30 September of around 16%.

  • The third point I wanted to make here is that we paid interest of around $9 million over the quarter with about USD5 million relating to the mezzanine debt facility, which is the high-cost element of our debt stack that we focused on specifically in the recent equity rates which I'll cover in the next slide.

  • The other key elements of the cash flow note is the sustaining CapEx as Mick mentions at around $13 million which is largely in line with Q2 and also in line with our broader CapEx guidance 2024 of around that sort of USD15 million.

  • So in summary, we are in an excellent position from a balance sheet strength point of view where we've delivered the balance sheet and have the ability to reduce our high-cost debt and continue to generate strong free cash flow from our operations as well.

  • On slide 7, as we outlined earlier in the year, a couple of our strategic goals for 2024 were to not only simplify but also deliver the balance sheet. We have delivered on these goals by not only reducing our net gearing by more than 6% since the start of 2024 but also simplifying our balance sheet by redeeming our private and public warrants early in the year.

  • Furthermore, as we announced on the 9th of October, we completed that successful placement as we noted of around AUD150 million, USD103 million. The placement as I said was extremely well supported from both new and existing institutional and sophisticated investors both in Australia and offshore, which we are very thankful for.

  • We are now well equipped to further optimize our balance sheets with the retirement of the existing $145 million mezzanine debt facility at the earliest practical dates with 16 June 2025 being the backstop date for that. So while also providing additional flexibility to pursue strategic inorganic growth opportunities. I suppose a key piece of feedback as we noted during the call with the equity raise as well from investors over the last year was around our cost of debt. And in particular, the, the mezzanine facility which carries a minimum interest of around 13%.

  • And with that increasing to 17% of the corporate price had to reduce to below $3.40 a pound. So at 13% this just takes up around $19 million of our cash every year. So definitely worthwhile in terms of being equative from a capital raise point of view to obviously raise the equity and pay that debt back as soon as we can. And to put this in context, we currently pay around 7.8% on our senior facility. So quite a big difference in terms of opportunity for us to reduce our overall debt cost.

  • We do need consent from the mezzanine debt provider to repay the debt before the 16th of June '25. So filing that, we will definitely be targeting the repayment of that debt on the 16th of June next year. So either way the debt will be retired by then.

  • So in summary, with the great support from our new and existing shells, we're now in a very strong and combining position and arguably, I mean, we are in the best position from a balance sheet point of view since the inception of the company. And as we noted, we've got some $226 million us of proforma liquidity, proforma net gearing down to 16%. And you know, we, we have the cash and the balance sheet to retire that high-cost debt and also provide that flexibility if and when we need it.

  • So with that Mick, I'll hand back to you.

  • Michael McMullen - Chief Executive Officer, Director

  • Thank you Morne, and I think you've only got to look at the cash waterfall to see the interest that's gone out the door to understand why we've taken the proactive steps of raising that equity in order to -- you know, I think get a debt facility or a series of debt facilities in place that are more reflective of the higher credit quality that we are today versus when we closed on the acquisition.

  • So moving on to the operational side again, strong quarter, you know, business as usual for us, I think just over 10,000 tons of copper. C1 again came down. We saw a reduction in mining unit rates, a total cash cost of about $2.70 a pound, which is pretty consistent with the previous quarter. And as I said, we broadly achieved spot price give or take a few cents a pound, sometimes a little better, sometimes a little worse. So we had USD30 million of operating free cash flow, which just continues to show you the strong cash flow generation potential of this asset.

  • And again, Q4, we do expect it to be the strongest quarter of the year, we sort of expect to exit the year in the fourth quarter, more or less at the run rate of midpoint of guidance for next year already. So, that's an encouraging sign I think. Grade again after, you know, sort of a weaker grade in Q1, which was sort of partly planned because of the stopes, the areas we were mining. Then we had the change of mine plan to focus our efforts in areas that gave us the best bang for our buck, I suppose you could say.

  • And again, around that 4% head grade for the quarter, which was sort of as planned. We are getting better dilution control actually due to better mining practices. And so that's helping a bit on the grade as well. I have had some commentary that we're mining above reserve grade and yes, we are, that's sort of the plan, but the areas we're mining, we are seeing better grade out of the plan.

  • If you recall the 2023 reserve was the first sort of new reserve this mine's had in a very long period of time. We did adjust the modifying factors quite a bit. And perhaps we've been a little bit heavy on the dilution, modifying factor because we're not seeing that amount of dilution when we mine this stuff now. And so in the 2024 R&R, we'll look to address that and perhaps that has a positive impact on the [serve grade].

  • The other interesting thing on this slide to note is development leaders picked up again, we've had some commentary around Q1 and Q2 that perhaps we aren't doing the development that's required. Just given the drop in the development meters, we had guided to development meters picking up in the third quarter and that's precisely what's happened.

  • And partly the reduction in development meters that's required is the new mine plan where we're focusing our efforts in a couple of areas. We're also, as you'll see in the exploration section here, seeing significantly more strike length on the ore body in QTS North and therefore tons for vertical meter are picking up, which means you actually need less development to get your ore tons out.

  • And then the last impact obviously is the Vent project. So as per the plan, we expect to see development leaders continue to pick up a little bit but good result by the team to have a 60%-odd increase quarter on quarter as we've moved to the new plan.

  • Morne, I might let you take the cost section of the slides here.

  • Morne Engelbrecht - Chief Financial Officer

  • Great, thanks Mick. So on slide 10, we're covering the process of mining costs per (inaudible) mine ton respectively. First, the processing cost per ton, more than Q3 was around $26 per ton, which was around 18% lower than Q2. With the key difference being a 10-day shut in Q2 which impacted the previous quarter. While processing rates for Q3 were pretty stable at 261,000 tons for the quarter.

  • Going forward, we would expect this to stabilize at the Q3 levels. And as we maintain operational consistency. On the mining cost per time comparison, we were 7% lower than previous quarter, mainly due to a higher portion of development meters incurred in the quarter with developing meters as Mick mentioned up 64% from Q2.

  • Again, going forward with the commencement of both the QTS South Upper and the Vent project, I would expect the level of development meters to increase which will drive further the level of capitalized costs from that perspective.

  • Going to slide 11, we cover G&A and the development cost per meter. On the G&A side of things, it's worth noting that we're getting more consistent on this metric with the main driver for the G&A being high than previous quarter being the one-off adjustments we made in the previous quarter, which was the reallocation of some of the consumables they were captured in G&A that should have been captured in mining and processing costs.

  • So we are now better managing and reporting those costs from an operational point of view. So again, going forward, I would expect these costs to be consistent with Q3, all things being equal. So on the other side, the development cost per meter, all they have increased from the previous quarter represents an average of the previous three quarters and are slightly elevated to not only the higher development meters as mentioned before, but we also have a slight increase in the equipment and workforce to cater for the new developments that has commenced. But also obviously increasing the production rates as well or keeping that consistent while we develop yourself up and the Vent project as well.

  • Slide 12. So this is moving to tonnes milled per employee, we do note the decrease in the metric albeit this is due to increase the mining headcount, as I mentioned previously by around 5%. This is to ensure the coverage from all positions to keep production consistent to carry out as we carry out the higher level of development.

  • Sustaining capex decreased slightly over the quarter. Again, largely driven by diamond drilling and Vent expansion drilling. We continue to spend capital in accordance with our previous diners, as we said around that sort of USD50 million for 2024 so consistent quarter on quarter.

  • So overall, the main focus here is on consistency in our operations and that's assisting to drive down our costs, increased efficiencies while we commence the key development projects that will materially drive and increase our production of around 25% over the next couple of years. So really consistency is the key and as we previously mentioned, we do have a large component of fixed costs. So the more consistent you can get and the more you can increase production, the better from a cost per ton point of view obviously.

  • With that Michael, I'll hand back to you for the remainder.

  • Michael McMullen - Chief Executive Officer, Director

  • Thanks, Morne. I would just note in terms of tons milled as we get better at dilution control, I'll always rather haul less tons of high-grade material up the hole than just hauling barren dirt up. So again, if we can continue to drive dilution down and maintain that higher head grade, you know, we may not actually mill as many tons, but as long as we get the copper out, that's a better outcome for us actually.

  • Moving on to the next slide, slide 13. We've just put out a more fulsome exploration release that has these diagrams in a broader format, so you can see them. So, we have delivered a significant resource and reserve upgrade last year. What's still to come? Well, we continue to drill away, obviously our reserves are only based on measure and indicated we have, you know, a significant amount of inferred and then that green material there, which is mineralized. So it doesn't quite make it into a resource.

  • Off notes. I'll run through a few of these slides, but off notes you can see there, there's a couple of drill holes that have skewed off to the left which is the southern side of QTS North. And if you refer to the exploration release, we put out, you can see the impact of those. They have extended the strike length of QTS North by 25%.

  • And one of those holes, the further one out managed to get 13.3 meters at 9.2% copper and another 4.9 meters at 10.9% copper. So, pretty exciting stuff actually that the team at site are discovering there and look this ore body clearly is not closed off in any way, shape or form. And we've been very successful at expanding that resource and it continues to throw up the kind of high-grade results that we've become a bit accustomed to that, perhaps are actually still quite special if you aren't working at [CSI].

  • So just looking at the slide. So the drilling has very much been focused on -- on converting that inferred mineralization and pushing the reserve or the material available for reserve down. And you know, again, super high-grade materials, you can see that our red material is the measure that, our orange is indicated and yellow is inferred and they just cut off at RLS, they're flat lines.

  • As we drill sort of at the bottom of the indicated and of the inferred that just pushes your measures indicated further down. And again, we continue to see very strong results. We always have something that's around 10 to 15 meters at 10%-plus copper, which is exceptional. And that high grade core that is present there allows us to mine all through the cycle, right. You know, we always have a very high-grade zone that we can always mine no matter what.

  • So Cutia Central is our other ore body, 20%-odd of our metal. Again, you can see here that we've -- it's a very lateral sort of classification system. And we've been quite successful at drilling down into the inferred and towards the bottom of the inferred and getting those sort of, -- you know, well, in fact, there's an interval there, that's about 25 meters at 5% or 6% copper, which is probably 15 meters. But still, it's a probably broader interval than we're used to seeing at the QTS Central. And then you've got your more typical 6, 7 meters intervals at 10% or 11% copper, which in most other mines, people would be doing, getting very excited about, for us it's just another day at CSA.

  • So the drilling has gone very well. We continue to sort of expand, both expand the resource, but also convert all this inferred material to indicated and measured. QTS South Upper, we've talked about this for a while. We've been drilling it, it is narrow, you know, 3, 4 meters wide, but it is very high grade. So again, you can see there that drill result of 3.8 meters at [7%, 8%]. It's shallow and 150 meters below surface. It's about 600 meters laterally from the decline to access QTS North.

  • And you can see here, we've elected to self perform this work. We have all the fleet on site, and I'm told that we took the first cut out of that this morning actually. So we've started development. We expect around about 10 months to first ore production out of this thing. It is not connected to the rest of the mine. It is not included in any of our guidance. The majority of that material is in inferred.

  • But it's sort of, -- we expect to be mining 100,000 tons of ore out of this thing at 5%, 6% copper. So you can work out what we think we're going to produce out of this thing in about a year or just under a year.

  • So, pretty exciting stuff. First new ore body that's been opened up here at CSA for, for some time. So we're pretty excited about this thing. We do have that high grade zinc mineralization up the surface. So over the east and west loads, the old mine which we continue to drill out. We do have a zinc load that sits over the top of QTS South Upper. Again, it's narrow but very high grade. And we intend to access this through this development that we're actually just starting today.

  • And we have an agreement with Polymetals to be able to treat that material up at the Endeavour Mill. And it does look like Polymetals are funded to get going and should be going sometime in Q2, I think next year, which will give us an outlet for that zinc material. So as some of you would know, we produce a very clean copper concentrate at high recoveries, 97%, 98% copper recovery. We don't want to send the zinc stuff through our plant. So this was a great solution for us actually. As more than I noted, our little investment in Polymetals is well in the money. So that's pretty pleasing as well.

  • Safety and TSF updates. So safety, we're gradually turning the corner on the TRIFR, we would like to see it lower. I would note that in terms of recordable injuries, you know, the TRIFR is being driven by the rates that we had back in sort of March and April. Pleasingly, we've significantly cut the number of recordable injuries in the last four or five months. It's just the one year trailing annualized effect that is continuing to sort of see it up. So as we move forward and we move out of that period from earlier in the year being counted, we expect to see this thing come down fairly quickly.

  • No reportable incidents or pollution events or license breaches or anything during the reporting period. I think that's evidence of the very strong community commitment that we have. We are about to commence stage 10 lift which will sort of see the capital, you know, that we've indicated sort of start flowing through. We've been spending a little bit under on where we thought we'd be for capital, but, you know, we expect to be back on the trend line for that, which is really effort.

  • So in terms of, what's the look forward everyone thinks about? Well, that's great. You know, you've delivered a good quarter again, we keep getting told consistency is the key. So look, we are delivering consistently. We're well on track to deliver at the midpoint of guidance for this year. And we have obviously the productivity improvements that we're doing, the Ventilation project and sort of midpoint of 2026 guidance is just over 50,000 tons. QTS South Upper is not currently in our guidance and I've sort of given you some indications of where that might come out, but we have now started that project.

  • So, you know, we're feeling quite confident about that pathway to plus 50. And we do know that, you know that the processing plant will handle what we've rather than annualized, 80,000 ton of copper, which is main place, our infrastructure will handle it. It's just a question of getting the ore out of the mine. And that's why we're doing some of these projects.

  • So, you know, ventilation is really critical for us, but also QTS South Upper, which is not connected to the vents at the bottom of the mine is also quite critical for us as well.

  • So, you know, in terms of our potential, you know, this is where we see our production going, you know, clearly our C1 as volume goes up, should come down a bit further from where we are. And as Morne indicated, our net gearing right now is around about 16%, which is a very comfortable level for us. You know, we think we're in a great position, actually having options is great, having lots of liquidity gives us lots of opportunities to do things. But clearly, we would like to retire that mezzanine debt at the first possible opportunity we can.

  • And so with that, you know, in terms of summary, you know, I think we're operating the mine very safely. We've got a 10 plus year reserve life, I think we're looking at the mine a bit differently than what has been the case for the last generation really. We have significantly delevered the balance sheet and we managed to get into the ASX 300 last quarter in the previous quarter into a few of the Russell indices in the US. So we are delivering on our strategic goals. You know, I think as I said, Q4 should be a little bit stronger quarter.

  • And again, I keep getting told that it was a little disappointing when we delivered a very strong Q2 and so that had some commentary, well, you can't repeat that. Well, actually, we can repeat that. Not only can we repeat it, but we can do a little better as we get our arms around the mine.

  • And I'd say, Rob and the site team have done a great job. Stabilizing the business now, that's the phase of operations we're in. We've gone through the sort of the large turnaround and significant change at site. I would say we're now in the stabilization phase of the operation and it's just consistent delivery is the key from here.

  • With that, I'm happy to turn over and take questions.

  • Operator

  • Thank you. We'll now begin the question-and-answer session. (Operator Instructions)

  • Sam Cattalono, Wilsons Advisory.

  • Sam Cattalono - Analyst

  • Good morning, Mick, Morne. We have very good quarter. Nice to see the operations as you say, sort of showing a bit of stability. Just a couple of questions. Firstly, just on your development meters, obviously that the stat that you're mostly talking about is the capital development meters. But in your release, if you add in the operating development meters, the last two quarters are still a bit below the prior two quarters before that is that just mine plan rather than sort of development limited. I'll leave it there and ask the second question in a sec.

  • Michael McMullen - Chief Executive Officer, Director

  • Yeah, it is mine plan related and partly related to the [double if stope strategy] that the team have implemented at site, it actually requires less operating meters per autumn. Like the short answer is we're doing the development that we have to do to get the all time best.

  • Sam Cattalono - Analyst

  • Okay. And just regards to QTS Upper, you've mentioned a few times that obviously it's inferred, it's not included in your guidance. And your waterfall chart makes clear the potential for upside to overall capacity from material coming out of their longer term. But in the medium term, once you sort of get out there and I think it's the back end of next year. Would material from that potentially add to your near term guidance or just displace other material from that sort of two, three-year guidance top figures?

  • Michael McMullen - Chief Executive Officer, Director

  • No, the benefit of this thing is it's completely additive. We're not mill constrained. And so, yeah, this would be on top of the current guidance

  • Sam Cattalono - Analyst

  • And then last question, Mick. Obviously, it's been a little bit of press around sort of talking about your involvement or otherwise in nervous call though. I wonder if you're in a position at all to say anything about that?

  • Michael McMullen - Chief Executive Officer, Director

  • Look, I think we've been clear that we look at every opportunity, if it's copper in a decent jurisdiction, we look at everything. I'd say not everything fits our criteria in terms of sort of value. And sometimes things are competitive processes and so we're very value focused. So as you know, I'm sure you are aware from another process, you know, hard to say where you land on any of these things. I would say we're active across lots of different things, but our fundamental thing is value for shareholders, right? So, when things are very competitive, sometimes it's difficult to get to value.

  • Sam Cattalono - Analyst

  • Yeah, understood. Thanks Mick.

  • Operator

  • Daniel Morgan, Barrenjoey.

  • Daniel Morgan - Analyst

  • Hi, Mick. Good morning. First question is just number one, have you initiated discussions with Sprott over the MS facility change out? I appreciate. It's a short time since you raised the equity.

  • Michael McMullen - Chief Executive Officer, Director

  • Short answer is yes. There's ongoing discussions actually with all the lender group. And again, to be clear, as we said, when we launched that equity raise, this was not a lender group driven equity raise. This was a MAC proactive opportunity. You know, we felt that, you know, by having the cash and the balance sheet put us in the best position to have that conversation with Sprott. So yeah, it's a work in progress

  • Daniel Morgan - Analyst

  • And you mentioned just then a discussion broader with the rest of the lending group. Would you think that you do that after the discussions with the Sprott are concluded or is it a parallel?

  • Michael McMullen - Chief Executive Officer, Director

  • Well, both is the short answer. Like you, when you have the amount of liquidity we have, I guess you have a lot of options. So, I think we, we want to be in a position of strength when we have those conversations and look when we put the current lending stack in place, I'm not sure we're in a position of strength.

  • And so you end up with -- I think the feedback we've had from investors has been the cost of the mezzanine debt seeing you not so much, but also the complexity on that debt stack, right. So what we're trying to solve for is (inaudible) cost, but they would like to solve for simplicity. So I know what Morne and I would like to see on the debt stack. But yeah, look, they're ongoing live conversations. So I can't really go into the detail.

  • Daniel Morgan - Analyst

  • I appreciate that. Just pivoting to the ops. So you've obviously flagged and guided for a better year in 2025 and beyond. But in 2025, simply is it going to, is the production growth expected to come from mostly tons so far, the better production as you highlight is, has come from grade,

  • Michael McMullen - Chief Executive Officer, Director

  • Similar grade, slightly more tons. But as I say, you know, we expect to sort of exit Q4 this year, more or less at the midpoint of next year's guidance already, right? So it's not like we're sort of having to do a huge step change in order to get there.

  • Daniel Morgan - Analyst

  • Yeah, so that would imply that tons this coming quarter should lift on what we've just seen in September.

  • Michael McMullen - Chief Executive Officer, Director

  • Well -- would be right as well. Let's see how we go.

  • But yeah, I think we sequentially, we'd expect to see slightly more tons. I would note though, if we can continue to get dilution under better control, it's metal tons that I'm worried about right. So you may not need to get more ore tons out if we can continue to squeeze that dilution.

  • Daniel Morgan - Analyst

  • Sure. And just on that dilution, is there any way you can quantify the dilution outcomes you've been experiencing recently? What versus what you've embedded in the reserves? Just to give a feel for the potential upside we're talking about with the grades that we're looking at on the reserve grade.

  • Michael McMullen - Chief Executive Officer, Director

  • Yeah, we're probably seeing 10% to 15% less dilution than expected. So, the previous reserve was at 4%. We were typically mining [3.7%, 3.8%]. We then reduced the reserve grade to 3.3% give or take. And now we're sort of seeing a bit higher grade. So, you know, I think we're likely to -- the work hasn't been finished yet. But if we squeeze that dilution in a bit, you will expect to see the grade go up a bit.

  • Daniel Morgan - Analyst

  • Thank you. And then last question, just what is the expected timeline and the cutoffs for drilling and the next resource reserve update? Just reiterate that,

  • Michael McMullen - Chief Executive Officer, Director

  • Yeah, like all North American companies, we will aim to get our R&R out towards the end of February just in time for that other company's large conference. So typically, yeah, so the cutoff, we will cut off at the end of -- I think we're going to try and cut off at the end of October this year.

  • Daniel Morgan - Analyst

  • Okay. Thank you so much, Mick and Morne.

  • Operator

  • Timothy Hoff, Canaccord Genuity.

  • Timothy Hoff - Analyst

  • First question I had was just around the mine tons versus mill tons. The first quarter, I guess it's been lower. Is that a draw on stocks? And just noting that I guess I get from previous site visits, it didn't feel like you had a whole heap of stockpile capacity, but just talking to lifting that mine tonnage next quarter.

  • Michael McMullen - Chief Executive Officer, Director

  • Yeah. To be milling a bit of stock, we can between everything we've got, I don't know, we've probably got 40,000 tons of stockpile between the bins in front of the mill and the stock stockpiles underground. Probably. Yeah, in an ideal world will mine exactly the tons that we mill. Doesn't always quite work out like that.

  • Timothy Hoff - Analyst

  • Yes. And in terms of, I think it's the June quarter numbers that you've reported. I think there's quite a few revisions to those numbers, recoveries, I think copper sold. What else is in there? There's a few other bits and pieces. Would you mind stepping through some of those? I think TRIFR went up.

  • Morne Engelbrecht - Chief Financial Officer

  • Yeah, maybe I'll cover that. So, in the June quarter, as you remember, we brought out our quarterly which was in terms of the timing was before sort of the half year report and reporting the additional presold tons. So when we reported the quarter, it didn't include those pre presold tons and obviously the associated costs that go with that.

  • So if you look at the half year report that we issued for the June half year, you will note that those have been updated in that 2.5 year report. So all we've done is basically just roll back those in terms of the quarterly numbers as well to make them match up to the half year numbers. In terms of that sort of timing difference with the presell tons.

  • Timothy Hoff - Analyst

  • And then I think perhaps finally, in terms of QTS Upper cash burn that we'd expect on a quarterly basis is a couple of million dollars a quarter, sort of fair to look at there.

  • Michael McMullen - Chief Executive Officer, Director

  • Yeah, that's probably not far off the mark two to maybe three when it starts picking up. You know, it'll be that takeoff point, you know, it does interact with the rest of the mine for about the first, I don't know, 125 meters, 150 meters. Once we get out there a bit further, we can tie into an vent race out there and that allows us to go independent firing.

  • So it'll be quite slow for that first, you know, I don't know, 150 meters of development and because we're self performing the work, we can sort of use that fleet in other parts of the mine and use some of those people in other parts of the mine. So certainly a significantly lower cash burn than if we were using a contractor for it. Because it's actually going to be relatively inefficient for a while until we can get out there. And actually, because we can use those people on other things, it will be relatively nominal for a while anyway.

  • Timothy Hoff - Analyst

  • Brilliant. Excellent. I think that's it for me. Thanks guys.

  • Operator

  • Eric Winmill, Scotiabank.

  • Eric Winmill - Analyst

  • Great. Thanks a lot Mick and team for taking my questions. Nice to see the results out. I think a lot of my questions have been asked already but maybe just quickly on the zinc mineralisation, the Upper zones. I assume you'll be mining that with your crews or you going to use contractors there or what's the plan?

  • Michael McMullen - Chief Executive Officer, Director

  • Yeah. Well, that actually is one of the reasons we've got owner mining in QTS South up because it's all up in the same area right. So we're not quite ready to sort of get going on that zinc mining yet. We just want to focus on QTS South Upper first. But yes, that's the plan as we can flick those crews and that fleet between those two opportunities right in the upper part of the mine eventually.

  • And look, we couldn't scope that up for a contractor right now, so just easier to do it ourselves. And we've got full flexibility at that point, right. So, yeah, that's the short answer is we'd like to do that with our own teams.

  • Eric Winmill - Analyst

  • Okay, great. Thank you, appreciate it. And just on slide 17, you talked about the tailings, any additional detail there in terms of additional lifts or you mentioned here this northern tailing facility.

  • Michael McMullen - Chief Executive Officer, Director

  • So we've got the stage 10 lift that we're about to start on. You can see in the background of that photo, there's a sort of a light brownie looking thing over on the top right there. That's the north facility that the state government owns, we don't actually own that. So there is an ongoing conversation about, you know, I think they'd like to see us take that. I think subject to the agreement, we can get around historical liabilities, that potentially is an option for us for the next lift after stage 10.

  • So that's an ongoing conversation. It will take some time. But that's why we're building stage 10 now. We've split it into two lifts, but the full stage 10 takes us out to about 2030, 2031 capacity. And then that gives us the time to see whether we can do something on that North facility out there.

  • Eric Winmill - Analyst

  • Okay, great. Thank you really appreciate it. All right. Well, congrats on the quarter and I'll hop back in the queue. Cheers.

  • Paul Hissey, Moelis Australia.

  • Paul Hissey - Analyst

  • Thanks, moderator. Just a couple of questions from me, Mick and Morne I just -- what is the, I guess the official sort of capacity on the mill at the moment? I know you've resolved some constraints with access to water, et cetera. Just trying to think about how the growth arrives over the next couple of years. Clearly there's some more ore sources coming online and better underground productivity. What's the plant currently capable of doing?

  • Michael McMullen - Chief Executive Officer, Director

  • Yes. Well, it depends which bit of the plant. But, you know, I guess the (inaudible) end, the back end can do 80,000 tons of copper a year and we have, you know, run it when we have the ore and the grade we have run it at that rate, you know, for days on end. So it's not like a theoretical capacity. So 80,000 tons of copper is the short answer.

  • Front end, 1.8 to 2 million ton a year depending on what we're feeding into it. Water capacity is actually our first constraint. With the water that we've got from Polymetals now, about 1.7 million tons a year is where we could get to. And if you look at the guidance that we put out and the tech report that's out there, which is, a year and a bit out of date now.

  • So, the current guidance has us getting to about 1.45 million tons a year, additive to that would be QTS South Upper which is, 100,000 maybe 150,000 tons of ore a year, pretty high grade. That doesn't come up sharp, goes completely separate. So, yeah, do I think we can get to 80,000 tons a year? I'm not sure I can see that today. You know, can we get into the mid 50s and maybe a little higher? Yeah, I think that's where we can see this going on.

  • Paul Hissey - Analyst

  • Okay. Thank you. Just a quick question on [TCRC]. Maybe this is a bit mechanical. But do you guys pay a fixed rate through the year and then that sort of gets reset at the start of every new year with benchmark discussions or can you just talk us through through TCRC?

  • Michael McMullen - Chief Executive Officer, Director

  • Yeah, look, it's actually a very good question. So we are on -- as people know, you know, we recap the offtake agreement to a very proper market arm's length offtake. So we are on annual benchmark TC. We, we were in LME week a few weeks ago. Hard to say where TCRC will settle lower is the answer. So we're currently, benchmark for this year is 80 and 8.

  • In my mind, I'm thinking 40 and 4 for next year, could actually be lower. We've seen negative TCRCs in the spot market but at 40 and 4, Morne, I think we worked out, we'd be saving around about $0.09 a pound off our C1.

  • Morne Engelbrecht - Chief Financial Officer

  • That's right.

  • Eric Winmill - Analyst

  • Yeah.

  • Paul Hissey - Analyst

  • And that net number and wherever you guys settle that's the number you pay for the whole 12 month period right?

  • Michael McMullen - Chief Executive Officer, Director

  • That's right. Yeah. And it's normal benchmark TCRC that settled, you know, with China, it could well settle lower than that, quite frankly. Would I be surprised if it's 30 and 3 or 25 and 2.5? No, but in my mind, I run 40 and 4 you know, just to be conservative, but look, clearly we're going to see a pretty, you know, a substantial clip off our C1 come January, $0.09 a pound, maybe a little more.

  • Paul Hissey - Analyst

  • Yes. Great. And then just one last question for me and it's around the, just around the capital raise and the funding, I guess. I just want to give you a chat a little bit more about the timing. I mean, I think you perhaps answered the question partly earlier when you said you having this money in the bank puts you in a stronger position to go and talk to your lenders.

  • But I guess I was particularly interested in the comment you made around you know, having the additional capital to provide greater flexibility to pursue strategic inorganic growth opportunities. Do I take that to mean that, you know, the cash is there to pay the mezzanine finance when you can. But if an amazing deal comes along beforehand, then repaying the mezz debt goes back down the back down the priority list and you utilize this capex for a deal. I just want to try and unpack, I guess the priorities there and particularly in light of your commentary.

  • Michael McMullen - Chief Executive Officer, Director

  • Oh, I think this cash is earmarked for repaying that mezzanine facility. And again, you know, I wouldn't want to Presuppose anything but, you know, if we were to find an amazing opportunity and if it was great value and if it required capital, we'd probably view that as a sort of standalone exercise, I guess. Because you wouldn't want to come out the other side of something, whatever you did -- if you did something and you still haven't solved for, you know, the mezzanine debt package.

  • So I think we're pretty clear that's what it's for. You know, obviously we're always going to want to maintain optionality, but, you know, I think there's a very clear use of proceeds for that funding and it's just a question around timing, whether we can negotiate something earlier or as Morne said, the long stop date is June of next year, that's what it's there for.

  • Paul Hissey - Analyst

  • Yeah, thanks. That's very claiming.

  • Operator

  • Hayden Bairstow, Argonaut.

  • Hayden Bairstow - Analyst

  • Good morning, Mick. I just wanted to just clarify on the tracking and your tons up the hole. I mean, you sort of talked about this quarter after quarter really. And it does seem to be still the limiting impact is. Probably more around your confidence of what you've actually done and obviously having more people on site probably helps a bit, but just getting those tons out of the hole and the pathway to increasing that over time, just get a feel for where we're at now. And we didn't get to by the middle of next year on tracking tons and where can you push the capacity limitation to, can it go away from that to something else?

  • Michael McMullen - Chief Executive Officer, Director

  • Yeah. Well, it's ton, it's trucking the tons, but it's also having the tons available, right? So it's that whole combination element and stope availability. You know, I think we've had a big focus on dilution control because there's just no point trucking barren waste up the hole, right? Like you just, ultimately, we would become ventilation constrained and so trucking barren dirt up the hole just takes ventilation away from trucking all right, like it's pretty simple.

  • So we got a big focus on it and it's consistency. I'd say, you know, the quarter was pretty good from that point of view. I'd always rather truck less dirt at higher grade than the other way. I think they've got the bottom of the mine, you know, the developments caught up, you know, when we got the mine, you know, they're a bit behind in development. We've sort of caught up. We've got the vent established down the bottom, the secondary vent down there.

  • So that's quite helpful. These double if stopes have been actually a bit of a game changer for us just in terms of actually cutting the amount of operating development that's required for autumn, which speeds up our cycle, which allows us to get more dirt out. It's also reduced dilution. So, yeah, we just expect to see a gradual tick up in trucking movements going up. But I do, you know, I'm always telling people no point trucking barren dirt up the hole, right. Like if we can not truck it, we shouldn't do it.

  • So, yeah, I think we'll just expect to see over Q4 and into 2025 just a gradual increase in trucking volume. But again, if they can continue to squeeze that dilution down and keep the grade at or above four or a bit, you know, increase it. That's a pretty good result.

  • Hayden Bairstow - Analyst

  • Yeah, for sure. I mean, just on the Upper stuff. Do you think mineralizations' not in the way or anything, or you have to mine some of it and the stockpile it if Poly's not going or is it just totally separate?

  • Michael McMullen - Chief Executive Officer, Director

  • No, it's a separate lens that sits out there that -- no, we don't have to tackle it. In fact, the mine plan that's done for QTS South upper admittedly based on mostly bird, but, you know, clearly we're not developing it without a mine plan. You know, specifically excludes that zinc material. So that'll just all be upside when we get there. I think Polymetals, you know, I think by mid next year they'll be ready to take material and we won't be out there before then.

  • Hayden Bairstow - Analyst

  • Perfect. Good quarter guys.

  • Operator

  • This concludes the question-and-answer session. I'd like to hand the conference back over to Mick McMullen for any closing remarks.

  • Michael McMullen - Chief Executive Officer, Director

  • Yeah, look, I think I'd just like to congratulate the team at sight. With a strong result, again, it's all about consistency. We've moved into that consistency phase, squeezing, increased production out of this thing and look as you can see from the exploration results, this is a phenomenal ore body that has a lot more to give. And so, you know, we expect to be able to be here for a long period of time mining this thing.

  • And I hope that people are starting to get a feel now that, you know, Q2 wasn't just a sort of a one off. We continue to be pretty strong here in delivery and just expect to see this production tick up. And we're very excited about QTS South Upper, this is a whole new sort of mining area that we're opening up. Completely disconnected to the rest of the mine. All of those constraints we've talked about banned trucking access, et cetera. All don't apply to QTS South Upper.

  • So, actually, we're pretty excited about that thing that -- you know, this time next year, we should have some production coming out of it and it's completely additive to our current guidance. So, thanks everyone for your time and we'll talk to you again at the next quarter.

  • Operator

  • This brings to a close today's conference call. You may disconnect your lines. Thank you for participating and have a pleasant day.
