Speaker 2

Thank you, Candice. Good morning, everyone, and thanks very much for joining us. In the Q1, we delivered another consecutive quarter of strong operational and financial performance with steady free cash flow generation and continued debt reduction. This was largely a result of our unique copper and gold production diversification that provides meaningful exposure to higher copper and gold prices and attractive free cash flow generation. I'll go into more detail on our first quarter operating and financial achievements throughout today's presentation, along with providing an update on many of the exciting growth initiatives underway to further enhance our copper and gold exposure.

Speaker 2

Slide 3 summarizes the strong financial performance that we delivered in the Q1. Consolidated copper production was 35,000 tonnes and consolidated gold production was 90,000 ounces in the Q1. First quarter production demonstrated the strength of our diversified operating base with benefits from the continued mining of high copper and gold grades at the Pampacancha deposit in Peru, continued high gold grades at Lalor and strong performance from the New Britannia mill in Manitoba as well as the operational stabilization efforts at the Copper Mountain Mine in British Columbia, we are well on track to achieve the production guidance metrics for all metals. Consolidated cash costs were a Consolidated cash costs were a remarkable $0.16 per pound of copper for the 2nd quarter in a row. This was primarily the result of continued high byproduct credits, partially offset by higher mining costs and lower copper production.

Speaker 2

Consolidated sustaining cash costs were equally impressive and decreased to $1.03 per pound in the quarter. Given this strong cost performance, we have affirmed our full year 2024 consolidated cost guidance and we are pleased to see continued cost efficiencies being realized throughout the business, which is a testament to the outstanding team we have at Hudbay. Revenue in the quarter was $525,000,000 driven by gold production and sales volumes that exceeded our expectations. This together with impressive cost performance led to adjusted EBITDA of $214,000,000 and adjusted net earnings of $0.16 per share. Operating cash flow before change in non cash working capital of $148,000,000,000 also exceeded expectations.

Speaker 2

After deducting sustaining capital expenditures and cash lease and community payments, we generated $87,000,000 in free cash flow this quarter. This continues our quarterly trend of generating positive free cash flow. And over the last 12 months, we have generated more than $350,000,000 in free cash flow. Our strong free cash flow generation enabled us to make additional progress against our deleveraging targets by completing a $10,000,000 repayment on our revolving credit facilities and reducing net debt by $44,000,000 during the quarter. As at March 31, our total liquidity increased to $619,000,000 including $284,000,000 in cash as well as undrawn availability of $335,000,000 on our revolving credit facilities.

Speaker 2

The decline in net debt together with the strong EBITDA generation, has improved our net debt to EBITDA ratio to 1.3 times Moving to Slide 4. Our Peru operations produced 25,000 tons of copper, 29,000 ounces of gold, 640,000 ounces of silver and approximately 400 tonnes of molybdenum in the quarter. While high grade copper and gold ore continued to be mined from Pampacancha in the quarter, the mill processed less Pampacancha ore than in the Q4 of 2023. This was in line with the mine plan and the typical ore feed blend of approximately 1 third from Pampacancha and 2 thirds from Constancia. As a result, we are on track to achieve our 2024 production guidance for all metals in Peru.

Speaker 2

Total ore mined in the Q1 decreased by 27% compared to the prior quarter in line with the mine plan, which included supplemental ore feed from stockpiles during the quarter as the operations advanced pit stripping activities. The Constancia mill performed well during the quarter with throughput averaging 89,000 tonnes per day. Ore milled was 2% higher than the Q4 of 2023, mainly due to the treatment of soft ore from stockpiles. Recoveries continue to be strong and in line with our metallurgical models with 84.9 percent copper recovery and 73.4 percent gold recovery. The operations benefited from strong cost performance, achieving lower cash costs and sustaining cash costs compared to the 4th quarter.

Speaker 2

Peru's cash costs were at a record low of $0.43 a 20% improvement over the favorable levels achieved in the 4th quarter and benefited from higher gold byproduct credits and lower operating costs. Sustaining cash costs were $1.06 or 12% lower than the 4th quarter, primarily due to the same factors. We are positioned well to achieve our 2024 cash cost guidance in Peru. Our Manitoba business also saw another Q3 of strong operating performance as summarized on Slide 5. First quarter production included 57,000 ounces of gold, 3,100 tons of copper, 8,800 tons of zinc and 220,000 ounces of silver.

Speaker 2

Production of gold in the first quarter was better than expected as a result of many operational improvement initiatives and record performance from the New Britannia mill. We are well on track to achieve our 2024 production guidance for all metals in Manitoba. The strong gold production was partly attributed to the successful implementation of improvement initiatives at Lalor that were completed in 2023 early 2024, including higher shaft availability, efficient ore hoisting, stope fragmentation reduction and mucking productivity enhancements. The New Britannia mill achieved record quarterly throughput of 18 70 tonnes per day in the Q1 due to ongoing improvement initiatives and effective preventative maintenance measures. The New Britannia mill recoveries of gold and copper were 89% 90 6%, respectively, in the quarter.

Speaker 2

During the Q1, we received a permit approval from the Environment and Climate Change Manitoba to increase the new Britannia mill production rate to 2,500 tonnes per day. This approval aligns well with our long term objective to further increase gold production at the Snow Lake operations by directing more gold ore from Lalor to the New Britannia mill to achieve higher gold recoveries. The Stall Mill processed 4% less ore in the Q1 than the prior quarter aligned with our strategy of allocating more Lalor ore feed to New Britannia. With the storm mill recovery improvement project completed last year, we saw consistent strong recoveries of gold, copper and silver in the Q1 and achieved our targeted gold recovery levels of 68%. Manitoba's gold cash cost was $7.36 per ounce, which is well positioned at the lower end of our 2024 cash cost guidance range.

Speaker 2

Gold sustaining cash costs were $9.50 per ounce in the quarter. Now moving to Slide 6, We continue to focus on advancing our operational stabilization plans at our British Columbia business unit. In the first quarter, 7,000 tonnes of copper, 4,400 ounces of gold and 88,000 ounces of silver. Production of copper and silver was lower than the prior quarter, while gold production was higher as a result of higher gold grades and overall higher recoveries. We are on track to achieve 2024 production guidance for all metals in British Columbia.

Speaker 2

Total ore mined in the Q1 was 3,700,000 tonnes, which increased 42% from the 4th quarter in line with our fleet production ramp up plan. The mill processed a total of 3,200,000 tonnes of ore during the quarter with mill availability averaging 90.4% while maintaining a stable throughput rate. Mill throughput was impacted by reduced reliability of the crushing circuit, which was caused primarily by elevated levels of magnetite and scrap metal as the mining progresses through areas of historical underground workings. 1st quarter milled copper grades averaged 0.27%, which was lower than the Q4 of 2023, but higher than the reserve grade of 0 point 2 5%. Copper recoveries of 83.4% were higher than the prior quarter and higher than expected due to relieving the regrind circuit constraint and implementing the flotation operational strategy improvements, including reagent selection and dose modification.

Speaker 2

Cash costs were $3.49 above the upper end of 2024 guidance range, but we expect these to decline during the remainder of the year as we continue to implement the stabilization initiatives. We have affirmed our full year cash cost guidance range for BC. Slide 7 highlights the improvements we have seen at Copper Mountain through the early stages of our stabilization initiatives. Since the acquisition in June of last year, we have achieved and exceeded the target of $10,000,000 in annualized corporate synergies and we are on track to realize the 3 year annual operating efficiencies target. On the mining side, we have remobilized idle haul trucks and accelerated the purchase of 5 new haul trucks to increase mining activities and improve flexibility in the mine with additional mining phases.

Speaker 2

To open up the mine, we have begun a campaign of accelerated stripping over the next 3 years to enable access to higher grade ore and to mitigate the reduced stripping undertaken by Copper Mountain over the 4 years prior to our acquisition. As a result of the remobilization initiatives, total material moved will continue to increase quarter over quarter in line with the mine plan. We continue to hire and train additional ore truck drivers and expect to have a fully trained complement of truck drivers this summer to support the expanded mining fleet, which is expected to increase material moves, improve operating efficiencies and reduce unit operating costs. Additionally, we are implementing plant improvement initiatives that mirror the successful processes at our other operations, specifically Constancia. We have seen stronger mill performance as demonstrated by higher mill availability and above target copper recoveries of 80 3.4% in the Q1 of 2024.

Speaker 2

The Q1 saw the highest quarterly copper recoveries achieved in the last decade at Copper Mountain. Stabilization benefits continue to be realized into April with 83% copper recoveries and approximately 40,000 tonnes per day average mill throughput, an increase of approximately 9% over the Q1. We are also accelerating engineering studies to debottleneck and increase the nominal plant capacity to 50,000 tons per day earlier than was contemplated in the technical report. Maintenance practices to improve mill availability continue to be a key pillar of the stabilization initiatives. The average mill availability during the Q1 increased to 90.4% from 85.1% last quarter, as I mentioned earlier.

Speaker 2

The maintenance programs completed during the quarter were fully executed according to plan. Additional maintenance practice enhancements are planned for rollout over the second and third quarter to implement the improved maintenance management processes and change the maintenance organizational structure. Several mill initiatives to target higher mill throughput were advanced during the quarter, including reprogramming the Mill Xpert system, installation of advanced sag control instrumentation, redesign of the sag liner package and updated operational procedures to remove magnetite from the pebble stream. The mill throughput in April increased to close to 40,000 tons per day as the mill began realizing benefits from the recalibration expert system. The benefits of the operational stabilization improvements are expected to be realized through the remainder of 2024.

Speaker 2

In March, we released our annual mineral reserve and resource update and provided our updated 3 year production outlook, which is shown on Slide 8. We expanded the mine life at Constancia by 3 years to 2,041 as a result of the successful conversion of mineral resources to mineral reserves by adding an additional mining phase at the Constancia pit. Manitoba reserves continue to support a mine life to 2,038 with significant extension potential through a conversion of the remaining 1 point 4,000,000 ounces of gold in inferred resources in Snow Lake. British Columbia reserves support the 21 year mine life disclosed technical report released in December of 2023 with additional optionality and upside potential for reserve conversion through 370,000,000 tonnes of inferred resources. Our 3 year production outlook highlighted that Constancia operations are expected to produce 101,000 tonnes of copper and 62,000 ounces of gold over the next 3 years.

Speaker 2

British Columbia's annual copper production is expected to average 41,000 tonnes of copper over the next 3 years. Manitoba annual gold production guidance continues to average 185,000 ounces over the next 3 years. Hudbay offers investors meaningful copper exposure, complementary gold exposure and strong near term cash flow generation. We are well positioned to benefit from strong copper and gold prices with our low cost stable operating platform in Tier 1 jurisdictions and our leading copper development and exploration pipeline. As shown on Slide 9, today Hudbay produces more than 150,000 tonnes of copper per year, which is further augmented by our complementary gold exposure that offers cash flow resiliency in volatile pricing environments.

Speaker 2

For each $0.25 annual change in copper prices, Hudbay will gain an additional $75,000,000 in cash flow and EBITDA. Similarly for gold, for a $100 per ounce annual increase in price, Hudbay will see $25,000,000 in increased cash flow and EBITDA. Our portfolio also generates the highest increase in net asset value with rising copper prices amongst our peers. Now turning to Slide 10, Copper World is the next promising greenfield copper development project in our growth pipeline. As we progress towards making a sanctioning decision, we will continue to be prudent with our financing plans for CopperWorld by remaining focused on meeting all of the prerequisites outlined in our 3P plan that we introduced in late 2022.

Speaker 2

Copper World is one of the highest grade open pit copper projects in the Americas with proven and probable reserves of 385,000,000 tonnes at 0.54% copper in Phase 1. There is roughly 60% of the total contained copper remaining in the measures and indicate resources, excluding reserves, which provides significant upside potential for Phase 2 expansion and mine life extension beyond 20 years. The Phase 1 PFS released in 2023 showed enhanced project economics and optimized flow sheet and a simplified permitting process with extended mine life to 20 years and an internal rate of return of 19% at a copper price of $3.75 per pound. The first key state permit required for CopperWorld, the mine land reclamation plan was initially approved by the Arizona State Mine Inspector in October 2021 and was subsequently amended to reflect a larger private land project footprint in June 2022. In late 2022, we submitted the applications for an aquifer protection permit and an air quality permit to the Arizona Department of Environmental Quality.

Speaker 2

We continue to expect to receive these 2 outstanding permits in 2024. We also received the floodplain use permit approval from Pima County in April 2024. We expect to launch the formal joint venture process later this year after we secure our permits and prior to commencing a definitive feasibility study, which would allow the potential joint venture partner to participate in the funding of definitive feasibility study activities as well as in the final project design for Copper World. We have seen strong initial interest from potential joint venture partners as many industry participants are focused on increasing copper exposure. Securing copper supply becomes a growing global concern as evidenced by BHP's recent bid for Anglo American in an effort to increase their copper exposure.

Speaker 2

Copper World will be a key contributor to the domestic U. S. Supply chain with our intention to produce made in America copper cathode by building a concentrate leach processing facility in the 4th year of operations. Local production of copper cathode would reduce the operations total energy requirements and lower greenhouse gas and sulfur emissions by eliminating overseas shipping, smelting and refining activities relating to processing copper concentrate. The project is expected to contribute more than $850,000,000 in U.

Speaker 2

S. Taxes, including $170,000,000 in Arizona state taxes. The mine will also create more than 400 direct jobs and up to 3,000 indirect jobs in Arizona. Copper World is an attractive copper growth project for Hudbay and our stakeholders, which will generate strong project returns and bring many benefits to the community and local economy in Arizona. We are also encouraged by the progress that the United States Mining Regulatory Clarity Act of 20 24 is making through legislative approvals as the government recognizes the importance of supporting the domestic critical mineral supply chain.

Speaker 2

Consequently, this bill aims to clarify the use of federal lands for mining critical minerals and also effectively overturns the prior Rosemont decision. While it doesn't change our path forward on Phase 1 of our Copper World plan, if passed by the Senate, the bill would be a positive development for the 2nd phase of Copper World when we expand onto federal lands and significantly increase the annual production and mine life at Copper World. It would also simplify this future permitting process for our Mason Copper Project in Nevada. Turning to Slide 11. In Peru, our exploration activity surrounding the Maria Reyna and Caballito properties near Constancia continue to focus on permitting and drill preparation.

Speaker 2

We commenced early exploration activities after completing a surface rights exploration agreement with the community of Uchicago in August 2022. As part of the drill permitting process, environmental impact assessment applications were submitted for the Maria Reyna property in November 2023 and for the Caballito property in April 2024. And in Manitoba, we initiated the largest exploration program in the company's history in Snow Lake as highlighted on Slide 12. Much of the newly acquired land from the Cook Lake and RockCliff transactions last year has been untested by modern deep geophysics. During the Q1, a surface geophysical survey was conducted over a portion of our Cook Lake tenements using cutting edge techniques that enable the team to detect targets at depths of almost 1,000 meters below surface.

Speaker 2

The multi phase 20 24 drilling program with up to 8 drill rigs during the winter focused on testing potential for deep extensions of the gold and copper gold zones at Lalor and will continue throughout the year testing other targets identified from current and past geophysical surveys. The goal of the 2024 exploration program is test mineralized extensions of the Lalor deposit and to find a new anchor deposit within tracking distance of the Snow Lake processing infrastructure, which has the potential to extend the life of the Snow Lake operations beyond 2,038. Additionally, we are advancing an access drift at the nearby 19 oh one deposit to enable infill drilling aimed at converting the inferred mineral resources in the gold lenses to mineral reserves. In the Q1, we commenced the development of the smaller profile drift from the existing Lalor ramp. The 1901 development and exploration drift is proceeding on schedule and on budget and is expected to reach the mineralization in late 2024.

Speaker 2

Definition drilling is planned for 2025 to further confirm the optimal mining method, evaluate ore body geometry and continuity and convert gold inferred resources to reserves. Additionally, in March 2024, Hudbay signed a 5 year option agreement with Marubeni focused on 3 exploration projects within trucking distance of FlinFlon. The agreement grants Marubeni an option to acquire a 20% interest in the projects following the completion of funding C12 $1,000,000 in exploration activities over a period of 5 years. All three properties host past producing mines with attractive copper and gold grades and remain highly prospective for further mineral discoveries. Concluding on Slide 13, we believe that copper has the best long term supply and demand fundamentals in the sector as global copper mine supply will be unable to meet demand from global de carbonization initiatives and growing demand from the use in AI data centers.

Speaker 2

Hudbay is uniquely positioned to benefit from the strong outlook for copper with a steady copper production profile of over 150,000 tonnes per year through to the end of the decade. Hudbay's resilient operating platform offers leading exposure to copper and unique complementary exposure to gold, which together with our quality pipeline of growth assets provides significant upside potential for further value creation at higher copper and gold prices. And with that, we are pleased to take your questions.

Operator

Thank you. Ladies and gentlemen, we will now begin the question and answer session. Your first question comes from the line of Jackie Chibulawski from BMO. Please go ahead.

Speaker 3

Hi, good morning. Thanks for taking my question and congratulations on a really tremendous quarter. It's really great to see. I guess my question is just on Peru. You mentioned in the MD and A that the Peruvian government is considering expanding or an option, I guess, to expand permits, including potentially, I guess, the Constancia.

Speaker 3

Can you tell me like is that something that practically, if you were able to extend your permit by 10% or so, is that something that would be within the mill's capacity to achieve that higher throughput? Or what would you guys need to do to get there? Thanks.

Speaker 2

Thanks very much, Jackie. So the way that I would characterize it is, there's a potential that this could increase future copper production at Constancia after the Pampacancha deposit is depleted in 2025 by achieving further economies of scale to offset lower grades. But I think what we got to remember is the regulation is currently a proposal and we'll continue to monitor its progress and the potential impacts on Constancia. Now that said, the team and I were in Peru a couple of weeks ago and we met with the Minister of Energy and Mines, the Minister of Economy and Finance, the First Minister, etcetera. And they intimated that the proposal is in highly advanced stages and is likely to be implemented very soon.

Speaker 2

That remains anecdotal. And specifically, what it will allow us to do is uncertain at this point. But we certainly would be looking at options to actually increase production by supplementing the process facilities that we have in place if needed. Andre, anything you want to add?

Speaker 4

Yes, sure. So that covers, I guess, what I'd say the permitting process and what they're looking at. And so in simple terms, what they're proposing is to increase copper production in Peru is authorizing within your existing permit permitted facilities opportunities for process improvement. So existing crushers and infrastructure that you currently have. And so what we do have, which is a benefit for us is we do have permitted pebble crushers that haven't been implemented.

Speaker 4

And the reason why we haven't implemented in the past is because we are throttled on the throughput capacity. So the teams are looking actively at what are the levers, if you will, around what we can do within that framework to take advantage of that 10% reduction. It's still early days, still early days yet, but we are running on days up to 94,000 tonnes per day. And so they're making continuous improvements in the process. And so we're quite optimistic that if this happens, that will be an upside for us.

Speaker 3

Thanks very much, Andre and Peter. And maybe just as a follow-up question. I attended the presentation by the Peruvian Minister at PDAC in March, And there was some talk there about streamlining permitting in general. I know your exploration projects in Peru have been very thoroughly going through the permitting process. Do you have any color or any optimism on whether streamlining of the permitting process for your exploration projects might be kind of forthcoming as well?

Speaker 2

I think, Jackie, so yes, I'm optimistic that, that is the case. All of the ministers of whom we met in Peru were keen to confirm that they're working hard to do that. That said, it remains to be seen what the bureaucracy can actually achieve. So the key elements really are as the middle of the EIA. And after that, there are a couple of other permits that need to be granted like archaeological And Consulta Previa kind of dwarfs the others.

Speaker 2

So we suspect that we'll be able to conduct the things like archaeological permit and the water use permit in parallel potentially with Consulta Previa. But the total duration we estimate right now is 12 to 18 months. We're hopeful that the 2018 gets reduced to 12 or so.

Speaker 3

That's great. Thank you very much for taking my questions and congrats again.

Speaker 2

Thank you.

Operator

Thank you. And your next question comes from the line of Orest Wowkodaw. Please go ahead.

Speaker 5

Hi, good morning. It's nice to see the free cash flow generation continue here in the quarter. My question has to do with costs. We saw very low cost per ton in Peru this quarter of just below $11 a ton. I mean that's probably the lowest number we've seen in quite some time.

Speaker 5

Is that sustainable? And can you talk about some of the drivers there? And then conversely, the cost per ton in Manitoba, Canadian 235 were among the highest that we've seen in quite some time. Just wondering if we should or can we anticipate cost to ease there for the rest of the year? Thanks.

Speaker 4

Sure. Sure. So I'll take it, Orest. So the cost I'll start with the cost in Peru. So the team has done an excellent job on cost conservation and looking for opportunities to reduce.

Speaker 4

And the forecast to the end of the year is pretty much in line with what you're seeing and within our budget ranges, maybe even towards the lower end like you're seeing this quarter. So there's nothing unusual about this quarter. It's just good operating practice, good cost control and they did overcome challenges with flooding and water and that while they did that. So we're really proud of the efforts of the team there. In terms of Manitoba, so the Manitoba one, if you look at it at face value, there's some increases at stall and overall a little bit in the mine.

Speaker 4

But it's part of the strategy. And so what we trialed in the quarter was with increased opportunity to put more ore through our productivity improvements are really taking hold. We've trialed putting somewhat higher base metal feed, if you will, from STAL that would normally go through STAL through New Britannia at better recoveries. And we were successful at that. So we're putting stuff from the lower cost mill or ore feeds through the higher cost mill, but we're generating a lot more cash by producing more gold ounces.

Speaker 4

And so at face value, the costs look a little bit higher than what they were, but it's all part of the strategy to make more cash. And so you saw the results in the goal for the quarter.

Speaker 5

Okay. Just to clarify, so in Peru, we should then I think what I'm hearing you say is we should expect cost per ton to increase for the rest of the year in order to get closer to your guidance range?

Speaker 4

It will be within the bottom to mid range of the guidance, yes.

Speaker 6

Okay. Thank you.

Operator

Thank you. And your next question comes from the line of Paul Profiti from 8 Capital. Please go ahead.

Speaker 7

Thanks, operator. Good morning, everyone. Peter, do you have a handle on the issue related to these elevated magnetite levels at Copper Mountain? It seems to be impacting the front end of the plant as opposed to the back end of the plant when we look at the success you've seen on copper recoveries. Just wondering what's the mitigation plan look like and just trying to get a sense of how important this issue is?

Speaker 4

Sure. I'll take that one as well. It's Andre. So I was up at site last week and I actually saw the site. So what the challenge is, is the pebble crusher as it as the pebbles get rejected from the SAG mill, there's a magnet on there to identify tramp or balls of metal that came out of the SAG mill.

Speaker 4

And when you put high magnetite through, the magnets can't discern between these still balls and the magnetite. And so by default, so you don't damage the pebble crusher, They were we were surging the pebbles back into the SAG mill, which reduced throughput. And so over the course of April, where you saw the increased throughput, what we did as a trial is we just rejected the pebbles. So at the so while we work for technologies to try to separate out what's magnetite versus the steel balls that are coming out, we just discarded the pebbles, restoring them in a safe spot for the future. Longer term, so we're seeing the benefit of increased throughput capacity by doing that in the short term.

Speaker 4

Longer term, some capital projects that we're looking at that will increase our throughput through the mills, will allow us to just recirculate those pebbles back into the pile and have come run as mine run of mine feed and not a surge into the mill of pebbles. And so we believe we've got it under control right now. We're looking at technologies, like I said, to separate or differentiate between magnetite and steel, but those problems will ultimately be solved like early next year with some improvements that we're planning in the mill.

Speaker 7

Okay. Got it. Got it. And Peter, I want to come back to the issue of the 10% potential permitted capacity increase at Constancian. Just wondering what special considerations outside of the plant that you may need to consider, things like power purchase agreement, things like trucking and logistics, things like tailings.

Speaker 7

Outside of the plant, are there anything that you're going to be paying closer attention to when you think about sort of the cost benefit analysis?

Speaker 2

Yes, Ralph. That's a great question. I think though that we are so used to the need to be a resilient operation in Peru that we plan for these types of things in advance in any case. So we have sort of search requirements for various aspects of our operational activities there. I think this is will be nothing exceptional for us.

Speaker 2

Don't think there'll be any additional logistics requirements. We have ample trucking capacity. We've increased our concentrate storage capacity. Frankly, I don't see any particular requirements arising out of this. Understood.

Speaker 8

Well done. Those are all.

Operator

Securities. Please go ahead.

Speaker 6

Yes. Thank you. Andre, question on Copper Mountain. You saw a step change in April both on mill throughput and mill availability. What happened in April?

Speaker 6

And is this sustainable?

Speaker 4

Yes. Great question. Thanks for that, Greg. So one of the there's an analogy one of our head metallurgists uses. It's like boiling water.

Speaker 4

You put a lot of energy into it and then eventually the bubbles start coming up. We've been putting a lot of energy and effort into the mill and all of a sudden you start to see the benefits coming through. The mill reliability in terms of so it's a measure that we've been it's a new measure we've been tracking and it measures the percent downtime due to unplanned events. For the quarter, we were about 96.4% and month to month from January, we're at 94%, February, we were at 96.4%, and March, we are at 98.4% reliability. And so month to month, we're seeing that reliability.

Speaker 4

The big step change that happened in terms of throughput was the implementation of or the optimization of the expert system. So the expert system is what controls the SAG mill feed and throughput. And so we have a 3 part system. 1 controls the speed of the mill, one monitors the density and one is the tonnage. And in prior days, only one of them was used, which was the tonnage input.

Speaker 4

In the month of April, we turned on all three. So we were running the expert system with all three parameters. And so that where the operators were more in a monitoring mode rather than dialing up the individual components. And so we're seeing the benefits of that going through in addition to like the prior question about the rejection of pebbles. So our intention is to continue as we're in high magnetite scenarios right now to reject them until we have some capital projects come in early next year that will solve the overall throughput.

Speaker 6

Fantastic progress. And a question for you, Eugene, on the gold hedging. Obviously, you've done a little bit. I think it's about 15% hedged on callers for the balance of the year. Do you intend to do more of that?

Speaker 8

Thanks, Greg. And no, not at this time. I think we did some modest hedging to Copper Mountain to protect some cash flows as prudent financial management during this stabilization period. Given the volatility we've seen in prices in prior years, it was sort of a prudent measure to keep ourself free cash flow positive. In general, our strategy is to provide the investors with the increasing exposure to both copper and gold and by prudently managing our cash flow to 1 acquire Copper Mound and stabilize it, we think we're giving investors kind of more exposure to that.

Speaker 8

So at this time, given where prices are, I think we're comfortable to let it with colors we have. If we see sort of a decline, we may want to ensure that we underwrite some of that. But given the strong copper and gold prices today, I don't feel the need to add additional hedges at this time. We'll let it ride.

Speaker 6

Great. Thanks, Eugene.

Operator

Thank you. Your next question comes from the line of Dalton Baretto from Canaccord. Please go ahead.

Speaker 9

Thanks, operator. Good morning, Peter and team. I've got a couple of questions as it relates to the 3P plan given what's happening in the copper market currently. I guess my first question is, how are you guys thinking about a hurdle rate for copper world, given the movement in the copper price?

Speaker 8

Hi, Dalton. 3P plant is a thoughtful plan that kind of looks throughout the cycle and the basis of that potential sanction division on the rate of return part was 15% IRR, a minimum of that at base prices. And when we put out that study, that was 3.50 copper and certainly, the PFS that we released last year achieved that. Obviously, at today's higher prices that we're going to see in the IRRs, if they were to hold during the period of build and through first production at those levels IRRs north of 20. And so certainly, that's one element of the plan that I think is clear on track.

Speaker 8

I mean, the current prices have allowed us to achieve deleveraging faster than originally planned. And we're very pleased with that result. And as I think Peter mentioned, over $200,000,000 of net debt reduction in the last three quarters since the acquisition of Copper Mountain and now we're at 1.3x net debt to EBITDA. So from a financial standpoint, we're getting towards that. I don't think we there's nothing to relax on the hurdle rate for investment in copper world.

Speaker 8

We think it's still prudent to have those strong IRRs that there's a significant work need to be done on planning and the feasibility study still. So the production, we know the project is a great project. As Peter mentioned, it's highest grade undeveloped copper deposit in the Americas at the reserve stage. And consequently, it has a very high returns. And that's the project that type of projects that IBE wants to invest in.

Speaker 9

Thanks, Eugene. So then given everything you just said, I guess my second question is, do you still want or need to do a deal on the project? And then Part B, I guess is, would you consider doing a deal ahead of the permits just to kind of take advantage of current market

Speaker 8

conditions? Again, we're going to stick with the plan here. The plan is to get the permits and get a partner. Given the attractiveness of the project, we expect that to there's lots of there's certainly lots of interest. I don't think front running the permits with a partner today in today's sort of hot environment is the right thing to do from a prudent planning basis.

Speaker 8

We're going to evaluate once we have the permits and how we move the project forward to create the most value for shareholders and potentially that partnership. But we're not I don't think you get the sustained highest value by doing this in front of the permits to try to get a quick win here. We want to look at this over long term in terms of what's best for the company in terms of the percentage we sell, the valuation of the project. And also as I think Peter highlighted in his remarks, the optionality of Phase 2 given the improved permitting environment. There's a lot of value there by just sticking with the plan here and executing.

Speaker 2

I think I'd add Dalton that there is occasional fierce debate amongst the management team about the options. But we typically land back at where Eugene that's the scenario Eugene has described. We'll continue to debate this going forward.

Speaker 9

And so then maybe one last one, if I can squeeze it in. As you look at Copper World and you think about buy versus build in the current environment, Can you talk a little bit about how Copper World compares to market valuations on a per tonne and copper basis?

Speaker 2

I'll kick off by saying that if you look at capital intensity, copper world is has a capital intensity of sub $16,000 an annual ton. So in comparison, Copper Mountain cost us about 12 1,000 annual dollars a tonne. But when you look at projects that others are building, they cost $20,000 to $30,000 to 40,000 dollars per annual ton. So if you could acquire if we could acquire something like the Cotton Mountain at $10,000 or $12,000 an annual ton, of course, we'd be happy to do it, but it's a bit of a unicorn. So we continue to try to find.

Speaker 2

But the ease of implementation of Copper World is extremely attractive, I believe. And it makes that the capital intensity, which stacks up very well against peer projects, highly, highly attractive. So in the absence of good acquisitions to buy, this is the way to go. And we've demonstrated in the past that we're good at this. And so we're excited to do it.

Speaker 8

I have nothing for the Peter.

Speaker 9

All right. Well, thanks very much guys. That's all for me. Congratulations.

Speaker 2

Thanks, Dalton.
