Speaker 1

Thanks, Gerald, and good morning, everyone. We're pleased to present our Q1 2023 results and achievements. Most importantly, And we're now on Slide 5. We're pleased to report that construction at our transformational Monteverde Development Projects or MVDP remains on time and on budget with nearly 3,000,000 tons of sulfide ore stockpile to date, ahead of our ramp up commencing late this year. The photo on the left shows some of the overall construction progress on the processing plants.

Speaker 1

While on the right, we can see sulfide ore being mined for the first time at Monteverde. This year is pivotal for KapStone as we expect to complete MVDP construction in Q4, setting the stage for a doubling of consolidated cash flow and positioning us well for future growth. I would also like to highlight that last week we reached a new collective agreement with the 2 labor unions at Montes Blancos. This follows successful agreements with our labor unions at Monteverde and Pincer Valley over the past 12 months. So for all of these operations, We now have agreements in place that cover the next 3 years.

Speaker 1

Turning to Slide 6. From operational standpoint, we experienced a challenging Q1 2023, marked by heavy rainfall at our Pinto Valley mine in Arizona. As a result, we produced a total of 40,700 tons of copper at consolidated C1 cash costs of 2.96 payable pound of copper produced. In addition to the weather related challenges at Pinsa Valley, at Montes Blancos in Chile, An emphasis on preventative maintenance resulted in more downtime and lower throughput. However, we were encouraged by very strong recoveries and Continued Strong Grades.

Speaker 1

At Monteverde, we mined lower grade oxides during the quarter, which had higher asset consumption. Furthermore, we carry over inventory with sulfuric acid at elevated prices. Although for the balance of this year, we have fixed approximately 80% sulfuric acid consumption at Monteverde at $140 per ton. Spot prices recently have decreased to below $100 per ton versus prices above $2.80 in 2022. Should prices hold at the current levels of $100 per ton, our C1 cost for oxides could decline by as much as $0.40 per pound next year.

Speaker 1

Lastly, at Cozamin, we were focused on developments and the ramp up of the pace backfill plant. Despite the slow start and turning to Slide 7 now, we are reiterating our 2023 consolidated production, cost and capital guidance. We anticipate production to increase sequentially quarter over quarter for the remainder of the year with a commensurate decrease in costs. At Pinto Valley, the operations improved sharply in March and the operation is now set up well with no planned major shutdowns over the rest of 2023. At the same time, grades and throughputs are forecast to increase, which can also be said for Cozamin.

Speaker 1

Lastly, at Manos Blancos, We anticipate higher throughput over the rest of the year. Now I'll pass over to Raman for our financial results.

Speaker 2

Thank you, John. We are now on Slide 8. In Q1, we recorded copper sales of 37,500 tons, which includes a sales lag of approximately 2,400 tonnes due to the timing of shipments in Chile. We expect to catch up on those sales in Q2. LME copper prices during Q1 averaged $4.05 per pound, up 12% compared to $3.63 per pound in Q4 2022.

Speaker 2

Given our QP hedging program hedges N+1 tied to our commercial contracts, our realized copper price of $4.17 a pound was slightly above the LME quarterly average. As a result, we recognized revenues in the quarter of 336,000,000 Adjusted EBITDA in Q1 of $65,200,000 was impacted by the sales lag, lower production and higher costs due to heavy rainfall in Arizona and a carryover of higher Q4 2022 sulfuric acid inventory into Q1 2023. The adjusted EBITDA figure also includes realized foreign exchange losses of approximately $9,000,000 and derivative losses of $8,000,000 Without the FX and derivative losses plus the sales lag, the EBITDA would have been approximately 85,000,000 Moving on to Slide 9. On the left hand side, we summarize our available liquidity, which as at March 31st was approximately $529,000,000 including $101,000,000 of cash and short term investments and $428,000,000 of undrawn amounts on our $600,000,000 corporate revolving credit facility. We are fully drawn on the $520,000,000 project debt facility as well as the $60,000,000 cost overrun facility with our Manto Verde partner Mitsubishi Materials Corp.

Speaker 2

As John mentioned earlier, we remain on track and on budget for completion of the Manto Verde development project by the end of the year. We ended Q1 with a consolidated net debt balance of $651,000,000 and attributable net debt balance of 492,000,000 The chart on the right hand side of the page illustrates our EBITDA sensitivity at various copper prices. You can see that 20 is overshadowed by the EBITDA generation with Manco Verde, sulfides at full run rate production. At $4 per pound copper, We expect to generate approximately $400,000,000 of EBITDA in 2023 and over $1,000,000,000 of annual EBITDA when Mantovari development project is online. Although the Santo de Minimal project is currently unsanctioned, the project has potential to further increase our EBITDA generation to about $2,000,000,000 per annum with metal prices at current levels.

Speaker 2

The EBITDA generation associated with Mantel Verde will enable accelerated opportunity to delever balance sheet and be below one times net leverage of copper prices between $3.50 $4 per pound, which provides additional liquidity to advance our future growth pipeline. Now I'll hand it over to Casio for the operations review.

Speaker 3

Thanks, Robin. We're on Slide 10. Pinto Valley produced 12,800 tons of copper at a C1 cash cost of $3.09 per payable pound during Q1, which is below our expectations, largely due to weather related challenges, specifically heavy rainfall in February led to stickier wet ore, which is more challenging to process and impacted throughput. But most important, it also prevented us from accessing some of the lower benches in the pit with some higher grades. Looking ahead, we are encouraged by strong production through April, and we are reiterating our guidance as we expect sequential improvements quarter over quarter.

Speaker 3

We also note, as John mentioned, that we have no significant maintenance scheduled over the remainder of 2023. In terms of our growth at Pinto Valley. We are increasingly enthusiastic about district consolidation potential. As a result, our efforts are now focused on analyzing the impacts of potential district opportunities, and we have deferred our PV4 study. Moving to Slide 11.

Speaker 3

Cozamin Mine had a transitory transitionary production quarter, producing 5,200 tons of copper at C1 cost of $1.72 per payable pound. Over the remainder of the year, we expect throughput and grades at Cozamin to increase. Today, we have also released an updated technical report at Cozamin to reflect changes in the mining method that we disclosed last quarter. The technical report features average copper of 20,000 tons at a C1 cash cost of $1.51 per pound and a higher average of 24,000 tons at a C1 of $1.46 per pound in the 1st 5 years. The new mine sequencing includes a combination of long hole and Cut and Fill.

Speaker 3

We've moved to this based on our experience with the ore body to date, and we believe this will provide for greater mining recovery than if we had continued utilizing only long hole mining methods. We also believe there are several opportunities to improve the life of mine plan, including exploration, refinement to cut and fill in order to reduce dilution and have the possibility of drift and fill methods to increase pillar and post recovery. On the exploration side, the Malinoche Footwall Zone deposit is still open to the Northwest, Southeast and Down dip. Armantos Blanco's asset is highlighted on Slide 12. Total sulfide and cathode production yielded 14,100 tons of copper at a blended C1 cash cost of $2.68 per payable pound.

Speaker 3

The sulfide operation produced their strongest quarter to date, led by higher grades and recoveries. Work now is focused increasing overall reliability and improving production uptime. On that note, production and costs were impacted by unplanned maintenance and process improvement initiatives in the quarter. In terms of growth, design work is ongoing with respect to mantos blancos Phase 2. Now on to Matto Verde, Slide 13.

Speaker 3

Q1 2023 oxide production was 8,500 tons of copper in cathode at elevated C1 cash costs of $4.02 per payable pound. As John had mentioned, Costs were impacted by lower production and carryover of high cost sulfuric acid in inventory. Most important significant progress was achieved at MVDP during Q1. Project progress now stands at 83% with $654,000,000 spent as of March 31. With many of the classical major escalator risks behind us and or materially diminishing.

Speaker 3

The total expenditure for the project remains at 825,000,000 and on schedule for year end 2023 wet commissioning. The Manto Verde development project will deliver blended C1 cost of below $2 per pound and produce 120,000 tons of combined cathode with the retaining wall and conveyances advancing well. Structural steel erection is also advancing well as evidenced from the progress on the copper Filtration Building, Column Cells and Rougher Cells. All major components are procured and on-site and are now in the final tie in stages. Slide 15 shows the copper concentrate thickener and a different perspective on the copper filtration and load out facility.

Speaker 3

The picture on the right clearly displays the advancement of the assembly of SAG and Ball Mills. The next Slide 16 shows the truck shop and the photo on the right shows the core solar stockpile and the reclaimed tunnels in preparation for the construction of the geodesic dome for dust control. On Slide 17, we highlight the interior of the desalination plant on the left, where the expansion to 380 liters per second is on track for completion in Q2. The tailings facility can be seen on the right. Now over to Wendy King for the sustainability review.

Speaker 4

Thank you, Cashel. We're now on Slide 18. In March, we were very pleased to announce our new sustainability development strategy, including specific greenhouse gas emission targets. The development of the strategy was a structured 12 month process with company wide stakeholder participation and aligned with our purpose and values. We have a robust governance process for oversight and execution of the strategy.

Speaker 4

The strategy is reflection of our firm commitment to sustainability and sets out our priorities, actions and targets over the next 7 years focused on 5 initial priorities: climate, water, Tealing, Biodiversity and Communities. In the climate priority, our target is to reduce greenhouse gas emissions from Fuel and Power by 30% by 2,030 compared to the 2021 baseline levels. For tailings, we target 100% of our tailings storage facilities to be independently assured for conformance with the global industry standard for tailings management by year end 2026. Turning to Slide 19 and reviewing our quarterly sustainability highlights. At Mantos Blancos and Manto Verde, we have completed the self assessment states for the copper mark assurance process, allowing us to move forward with the independent review in Q2.

Speaker 4

We have also completed the human rights assessment update and our annual review of gut grievance mechanism completed the copper mark gap assessment and begin planning projects to formally fill any identified gaps to proceed with the copper mark assurance process at Pinto Valley. At Manto Verde, we've implemented retainers for concentrate shipments, which are considered best practice in the industry. Rotainers are an ESG friendly transportation solution as they provide for a dust free operation. The concentrate container is fitted with ISG's patented removable hard lid and sealed. The design also ensures no contaminants can build up and accumulate on the exterior of the containers.

Speaker 4

At Pinto Valley, we have a donation program with the Navajo reservation, whereby some of our non sellable copper is used for constructing jewelry and other crafts. We received the photo on the bottom right recently showcasing some of the crafts created by students at the reserve. Our inaugural combined sustainability report, Growing Responsibly, is well underway and will be published in early Q3. We are working to incorporate more climate discussions in our mainstream disclosure documents beyond the sustainability report to deepen our disclosure on the 4 TCFD areas, Governance Strategy, Risk Management and Metrics and Targets. And with that, I'd like to turn it back to John.

Speaker 1

Thanks, Wendy. On Slide 20, we highlight the significant catalysts we have over the next 2 years that supports our sector leading growth plans with further upside beyond this across our portfolio. We have a talented technical team in place and are working with strong engineering firms to execute on these studies, and we look forward to releasing the results

Speaker 5

in the timeline shown on the slide.

Speaker 1

Specifically, by year end, we plan to release our MVDP optimized study, which is targeting increasing throughput from 32,000 tons per day to up to 45,000 tons per day with no major capital equipment upgrades required. We're also contemplating a potential further expansion, which could include the installation of a second processing line. Meanwhile, we're busy at Montes Blancos evaluating the potential to increase throughput from the installed 7,300,000 tons per annum to 10,000,000 tons by the existing underutilized ball mills and processing equipment. And to round out the year, we plan to release an updated feasibility study for Santo Domingo in December. And to conclude on Slide 21, we reiterate that we are in the midst of a transformational year for KapStone.

Speaker 1

We remain laser focused on the execution of our near term growth profile, increasing copper production by 45% to approximately 260,000 tons following the ramp up at the Monteverde development project. After this, We have the fully permitted Santo Domingo project, which unlocks district synergies and generates an additional 45% of copper production to 380,000 tons per year with further upside and expansions across our portfolio. With that, we're now ready to take questions.

Operator

Thank you. Ladies and gentlemen, we will now begin the question and answer Your first question comes from Orest Wowkodaw with Scotiabank. Please go ahead.

Speaker 5

Hi, good morning. Nice to see the progress at the Mano Verde Sulfide project. Given that you're, call it, within 9 months of completion. Can you maybe just walk us through sort of what the critical path here is and where you see the biggest risk to that year end startup time line at this point.

Speaker 1

Yes. Thanks for the question, Ares. And I would sort of Start off by just sort of reiterating the fact that most of the kind of classical risks are behind us. The infrastructure is in place. The major equipments on-site, the major equipments actually installed already.

Speaker 1

We're now into the sort of the pipe installation, the electricals,

Speaker 6

all

Speaker 1

of those pieces. But certainly, what we see at this stage is nothing that gives us concern in terms of the time line. I think projects can kind of spring surprises on you, but I think We feel that sort of we've got all of those elements under control and we've basically sort of derisked sort of on all the possible kind of contingencies that we could see arising. I'll just pass across to Kassel, see if he'd like to add anything further to that.

Speaker 3

Yes, John, I think you've outlined it well. The major risks we see in projects that are being executed in the last few years are usually the major one is usually a geotechnical risk And we've made quite great progress in the major material movement required there. And so While we still watch that and evaluate that, we feel we're in a very good stead that the tailings dam and Geotechnical works are progressing really well. And then the other one classically we saw during the pandemic period was electrical and instrumentation. And I'm happy to say the electrical e rooms have arrived, Most of them and they're in progress and being delivered.

Speaker 3

So what I would say is the major risks that we have seen in projects in the last few years Are sort of behind us. So now they're the classical or the more rudimentary man hours, pulling cable, placing pipe and bore in place and those types of things, which are just the effective man hours and efficiency of those man hours on a project. So it's I would say right now we're at the boring risks with a project and it's just getting the work done.

Speaker 1

Yes. And I guess maybe one final comment is Obviously, the other element that one always looks at is ramping up the mine itself. And our final pieces additional mining equipment arrived some months ago. We're sort of fully now ramped up and we're now actually stockpiling sulfide ore ahead of the plant. And I think we said earlier, we've got around 3,000,000 tons of sulfide ore stockpiled already.

Speaker 1

So I think that also gives us a lot of confidence in terms of the subsequent ramp up.

Speaker 5

Thank you. Just as a follow-up and by the way, boring is good on projects like this. What do you plan to do with the construction team Once you finish here at Mano Verde, like I assume you're going to pause before starting Santo Domingo. But do you demobilize and then Remobilize in the future. How do you think about that right now?

Speaker 1

Yes. I think that's a really good question, And we've obviously got sort of 2 elements to that. The one is our owners' team, and we certainly intend to keep our owners' team intact. I think we obviously I think for us, the sort of next step as we move to Santo Domingo is obviously ensuring we have Monteverde fully ramped up. We obviously want to complete the financing of Santo Domingo and we want to sort of have a look at the macro environments at the time.

Speaker 1

And those three items will sort of guide our timing on decision making to sort of take a full notice to proceed on Santo Domingo. But I think we can certainly keep our full project team well occupied during that time. I think whilst we might not take a decision Full notice to proceed. That certainly doesn't stop us from progressing the engineering work, which in any event is the sort of first stage of a project. To really moving the engineering work and increasing the confidence in all the parameters within the project.

Speaker 1

I think the other element is our key contractor. And I don't know if you're aware, but recently we've changed contractors at Santo Domingo. We've move from POSCO to Osenco, the same contractor that we have at Monteverde. And the intention there is also to ensure that continuity of experience and people from Monteverde across to Santo Domingo. So I think certainly the core elements of both teams, The intent is to have retained for the Santo Domingo project.

Speaker 5

Thanks, John.

Operator

Your next question comes from Dalton Barotto with Canaccord. Please go ahead. Your next question comes from Bryce Adams with CIBC. Please go ahead.

Speaker 6

Yes. Hi. Thanks, John and team for taking my question. Just one for me. I wanted to ask on a single and the lump sum contract for Manto Verde.

Speaker 6

When we were on-site last November, there was a discussion around inflation Such a KapStone was less ex inflation because of the lump sum contract and that Osenco would be more exposed, But they were maintaining margin because of favorable FX rates. FX rates have changed since November, and I was wondering if that dynamic with Asenka has also changed And if there was any increased counterpart party risk from the change in FX, obviously, the best contract is a win win contract. So is that still the case with your partner?

Speaker 1

Yes, it is, Bryce. And I think very fortunately, Orsenco had also locked in a lot of its basically sort of underlying costs, so sort of all of its equipment, subcontracts, etcetera. And a lot of the, I guess, sort of main exposure to FX, I think, was Sort of was earlier on in the project. So at this stage, we certainly I fully agree with your comment that Despite being a lump sum turnkey contract, it's always important that everybody is making money. And Certainly, from what our discussions with Osenco show is that the project is still working well for them.

Speaker 1

Got it. Thanks so much.

Operator

Your next question comes from Craig Hutchison with TD Securities. Please go ahead.

Speaker 5

Hi, good morning guys. Just one question for me as well. Just on Mentos Blancos, You guys have sort of bumped around the 15,000 to 16,000 ton per day for the last several quarters. I recognize in your MD and A disclosed that you Had I think 18 days at sign of 20,000 tonnes per day and there was some preventive maintenance done in the quarter. But can you just give some context as to what that preventative maintenance is and whether you feel confident that we can get to that 20,000 tons per day here in Q2 or the next quarter or so.

Speaker 5

Thanks.

Speaker 1

Thanks, Craig. And I'll refer that question across to Kassel.

Speaker 3

Sure. Thanks, Craig. Yes. Quite often, starting with a clean slate, I think we've said this before, It's easier than starting off with a sort of a combined brownfields development where you're utilizing old equipment with new equipments. And there were certain constraints in the beginning of this project when it was under the private equity world.

Speaker 3

And I think those are things we're working through and we have been working through. The way I describe the project is the major components are there and they have been there since the beginning. They were designed well. They're capable of the throughput, but some of the interconnectivity might not have been engineered extremely well. And we've been working our way through it on a basis of trial and error.

Speaker 3

But I think we've changed our tactics And so I have much more confidence now that we've worked our way through many of the critical issues where some of these Minor bottlenecks have interrupted some of our consistent production due to maintenance interruptions. And we see that and we can track that by evaluating how much preventative maintenance we're doing versus breakdown maintenance we're doing. And those metrics are all we're seeing the right side of those and seeing them through. And it's working through where maybe a pump was overlooked Maybe a pipe was overlooked, and now we're starting to see the performance more on a more consistent basis. So the bottle the nameplate capacity is target is still 20,000 tons and we see ourselves reaching that very shortly and on a much more consistent basis.

Speaker 3

So it's been a different type of ramp up than would be a brand new construction, which has a different sort of level of engineering and evaluation applied

Speaker 5

to it. There's more of

Speaker 3

a learning curve on this one.

Speaker 5

I guess no major capital will be required to kind of improve some of those efficiencies at this point. Is that correct?

Speaker 3

No. And that's the key is the initial project looked after the major capital. And so now it's about the nuts and bolts, and we're working our way through it. And I think we've got a great plan moving ahead here.

Speaker 5

Thanks guys.

Operator

Your next question comes from Dalton Berrado with Canaccord. Please go ahead.

Speaker 7

Sorry, I dropped off there somehow. I want to start by asking about Mancha Verde again, and I apologize if these questions have been asked already. I just dialed back in. But you're mining the sulfide ore now, you've got 3,000,000 tons sitting on surface. How does that compare to your block model on what you were anticipating?

Speaker 7

Any surprises there?

Speaker 1

I'll answer initially and then I'll pass across to Kassel. But I think one of the advantages we had was We really drilled up the sulfide ore body well beforehand. So if you look at the full life of mine plan for the current Montevideo project, We have 70% of the reserves in the proven category and 30% in the probable for the entire life of mine. Now That's a higher confidence level than most mining companies have just for the next couple of years. So it gives us a huge amount of So geological confidence in the reserve.

Speaker 1

And so far, sort of what we have found is exactly in line with our model. I would say that what we also are finding is in areas where we have not shown reserve or resource, but that's kind of interlinked between sort of existing pits. We're also finding some really encouraging holes that are going into those as well. So we do expect over time to sort of add to those Reserves and Resources, and I think that will be that will certainly be accretive. Kessler, is there anything you'd add to that?

Speaker 3

Yes. I mean, the only reconciliation, of course, we could have on a stockpile is blast hole data against diamond drill hole data, And it more or less agrees. So it's looking well and it's given us the confidence. We have different stockpiles. We have transition material.

Speaker 3

We have high grade sulfide material and then we have run of the mill materials. And that's to sort of optimize our ramp up Such that when we're at lower recoveries, we can put through material where we're not exposed to Those lower recoveries to lose copper, but then again, we have the high grade material to put through when the plant has ramped up and we can get revenues as soon as possible. So, they've planned it out really well. And like John said, actually, the You might call the deposit over drilled for a measured reserve. It's down to 25 or 35 meters in some places on the diamond drilling and has greatly reduced The risk of having surprises in grade or in quality of material.

Speaker 7

Okay, great. Thanks for the color there. And then just kind of thinking about the studies on MANTAVERDE or study on MANTAVERDE That's coming out later this year. Just to clarify, will that study include both the optimization as well as The anticipated Phase 2 expansion with the second line or will it just be the optimization?

Speaker 1

So Dalton, the MV optimization is obviously where we're putting our primary focus right now because that's the most immediate opportunity that we have. We overdesigned the crushers in the mills such that those major pieces of equipment We believe can process sort of 40,000 to 45,000 tons a day versus the current project design of 32,000 tons a day. So our expectation is to have that feasibility study completed by the end of this year. And that's something which We don't foresee this being a major CapEx project, but obviously one which generates very, very significant additional returns. So we would look to sort of permits and implement that kind of ASAP.

Speaker 1

With the sort of months of ADIT Phase 2 that we'd be looking at a full second line. And those studies continue, But I would say it's sort of obviously an earlier stage and we ultimately want to make sure that we optimize that project according to the ultimate capability of the ore body. And so I think whilst our immediate focus will be on Monteverde optimized, In parallel, we'll also be sort of starting to drill up some of the sort of further parts of the ore body well, of the concession area, Just to make sure that sort of that second line is the optimal ultimate capacity to go to.

Speaker 7

Got it. Okay. And then sort of a similar question on Santo Domingo. Sanco is doing the study now. Are they

Speaker 8

going to consider the broader district and all of the synergies?

Speaker 7

Or are they going to The broader district and all of the synergies or are they going to optimize Santo Domingo on its own?

Speaker 1

Yes. So the Santo Domingo feasibility study is really being up the original feasibility was done in 2018. And what we're doing is updating it for 3 elements. The first is sort of inflation. The second is exactly the point you're asking about is the synergies that we have between Monteverde and Santo Domingo.

Speaker 1

And then the third is actually some design optimizations. The footprint, for example, at Monteverde is sort of far smaller in terms of layouts and more efficient in the previous design at Santo Domingo. So we believe we can take out about 35% of the footprints just by a more efficient Layout and Design. Now just going back to those synergies. So this study will include Some of the synergies that we identified in November last year.

Speaker 1

There are others that are more on the revenue side And those are, for example, the processing of the Santo Domingo Oxides and the processing of cobalt at Santo Domingo. Those are studies in their own rights that are being run-in parallel. And I think from recollection, we're actually due to present those sort of more like in sort of 2024.

Speaker 7

Okay, great. And then just maybe if I can squeeze one more in. This deferral on the PV4 study, Are you able to talk at all in terms of what you're thinking in terms of broader scope and opportunities as well as kind of timing and when all that could come together?

Speaker 1

Yes. Look, I'll answer your second question first. And I guess in terms of timing, Our immediate focus is completing the Monteverde development project. From there, we'll be moving our focus across to Santo Domingo and probably doing the optimization at Monteverde in parallel. So that does give us time to really look at the Pinsa Valley area, work out what is the optimal development plan for that as a district.

Speaker 1

And We've got enormous resources there, sort of 1,500,000,000 tons sort of in total at Pinsa Valley. We've been doing work sort of on BHP's Copper City's site next door. We believe there's another sort of 1,000,000,000 tons or so of resource there. All of it sits at sort of a grade of I think we Talking about 0.33 percent copper. Now ultimately, our view is that by developing a large scale processing plant.

Speaker 1

One can actually achieve highly, highly competitive costs. And obviously with these being porphyries, we believe you could sort of get decades decades of sort of flat lining production So without any grade decline, at highly competitive costs by sort of the most sensible sort of working out what is the most sensible scale and how does one fit that all together in the best sort of in the most efficient possible way in that as a district. So there's a lot of work to be done there, but I think we have kind of the time on our side to do so. And I think finally, it's an area that's been mined for the sort of past 100 years at least. And so we believe there's a lot of benefit in terms of the plans we have to develop this district that would also have very, very significant environmental benefits in terms of mitigating some of the environmental issues that have arisen from past operations in that district.

Speaker 1

And so we think It's a real sort of win win solution for that district.

Speaker 7

Thank you for the color, John. That's all for me.

Operator

Your next question comes from Stephane Lanoue with Cormark Securities. Please go ahead.

Thanks very much guys. Most of my questions have been answered or asked already. Just curious on Cozamin, I'm just looking at the updated mine plan, good to see. Just reading between the lines when I look at the sort of annualized mill throughput that's in it. Is there can I presume there's still a little bit of untapped capacity there?

Speaker 8

And is that just function of maybe being a bit conservative on how much ore you can pull from the underground.

Speaker 1

Yes. Thanks, Stefan. And I'll pass that one across to Kassel.

Speaker 3

Yes, Stefan. Hi. You're absolutely right. The plant itself is the processing plant is capable of 4,500 tons a day and so too is the paste plant dry stack facility we have. So Truly, the production bottleneck is the underground.

Speaker 3

And certainly, We felt that sticking with the previous methodology of mining was limiting our opportunities to increase production there. As you've noted, the technical report is maintaining the current production profile. But I think as we improve our competencies In the cut and fill methodology, it gives us a few other opportunities there in drift and fill, which will enhance our ability in the high grade areas to get greater mineral recovery And the sort of 80% to 90% that we would have in a normal cut and fill environment. And that gives us the ability maybe to extract some higher grade pillars and that would give us the ability to increase our mineral recovery and slow down some of our capital development. The other, of course, is the transverse mining method that we're including.

Speaker 3

We had solely a long haul retreating method, sublevel retreat. And the transverse mining method will give us a higher greater opportunity also to recover in a sequential fashion those pillars. So we could do pillarless mining in Some of the areas to be able to sequence with the pace fill plan. So We were a little bit conservative, I would say. Those are your words, but what we were is we were prudent in putting out a life of mine plan that is achievable, deliverable and has been executed before.

Speaker 3

And it will now be the challenges to the mine to increase the opportunities given to them with the infrastructure at the PACE plant and the underground new mining methods to increase production out of there, because certainly we have the capacity on surface to be able to mill more.

Speaker 8

Okay, great. Got it. Thanks very much for that.
