Thank you for standing by. This is the conference operator. Welcome to the Ero Copper First Quarter 2024 Operating and Financial Results Conference Call. The conference is being recorded. I would now like to turn the conference over to Courtney Lynn, Senior Vice President of Corporate Development, Investor Relations and Sustainability. Please go ahead.

Thank you, operator. Good morning, and welcome to Ero Copper's first quarter earnings call. Our operating and financial results were released yesterday afternoon and are available on our website, as are our financial statements and MD&A for the 3 months ended March 31, 2024. On the call with me today are David Strang, Ero's Co-Founder and Chief Executive Officer; Makko DeFilippo, President and Chief Operating Officer; and Wayne Drier, Chief Financial Officer. We will be making forward-looking statements that involve risks and uncertainties from which actual results may differ materially. We would refer you to our most recent annual information form available on our website, SEDAR, and EDGAR for a discussion of the risk factors of our business and their potential impact on future performance. As a reminder, and unless otherwise noted, all amounts are in U.S. dollars. I will now pass the call over to David Strang.

Thank you, Courtney, and thank you, everyone, for joining us today. We've had a great start to 2024, driven by the strong execution of our growth strategy coinciding with highly favorable market conditions for copper and gold. During the quarter, copper prices rallied to their highest levels in nearly 2 years, fueled by rising demand expectations, while the supply outlook remains extremely constrained, as evidenced by our recent treatment and refining charge negotiations where we locked in 2-year TC/RC terms in the low teens on roughly 1/3 of our projected concentrate production. At the same time, due to macro and geopolitical uncertainty, gold prices hit all-time highs. These positive trends in both copper and gold markets arrive at an opportune time as we are on track to reach our highest annual production levels ever. This includes anticipated contributions from the Tucuma project which is now approximately 97% complete. I'm also happy to share that commissioning of Tucuma is advancing ahead of schedule, and as a result, we are narrowing our projected timeline for initial production to early Q3 '24. While Makko will delve into more detail on our progress at Tucuma, I want to express my deepest gratitude to our team on the ground, which just marked over 5 million hours of work completed with 0 lost time injuries. This is an incredible achievement, and I commend our leadership team at Tucuma for the strong safety culture built over the past 2 years. As we rapidly approach an important inflection point in our consolidated copper production profile, I'm also pleased to report that our Xavantina Operations are on track to deliver record gold production again this year. In fact, during the first quarter, we produced 18,234 ounces, representing an increase of nearly 5,800 ounces or approximately 47% compared to the first quarter of 2023. This increase is attributable to the successful completion of the NX 60 growth initiative last year as well as higher-than-expected gold grades, which averaged over 16 grams per tonne during the period. This performance also resulted in unit operating costs for the quarter that were below our full-year guidance. More specifically, C1 cash costs averaged $395 per ounce in the quarter versus our 2024 guidance range of $550 to $650 per ounce. And All-in Sustaining Costs per ounce averaged $797 versus a full-year range of $1,050 to $1,150 per ounce. Given the continuation of positive grade reconciliations and additional visibility into mineable grades for the remainder of the quarter from indoor development channel samples, we are raising our 2024 gold production guidance from 55,000 to 60,000 ounces to a range of 60,000 to 65,000 ounces. Consequently, we are guiding to the low end of our full-year gold C1 cash cost and All-in Sustaining Cost guidance. With gold prices continuing to hit all-time highs, we are well positioned to deliver record operating margins and cash flows at Xavantina this year. At our Caraiba Operations, our performance during the quarter was largely in line with our expectations. From a strategic execution standpoint, we made good progress at the new external shaft, where we remain on schedule to reach a projected depth of approximately 600 meters by year-end. Upon our anticipated project completion at the end of 2026, this shaft is expected to reach a depth of over 1.5 kilometers, making it the second deepest shaft in South America. From an operational standpoint, we started to see the positive impact of the recently completed Caraiba mill expansion during the quarter, with tonnes processed up over 5% compared to Q4 at approximately 853,000 tonnes. This increase in mill throughput partially offset a planned decrease in mined and processed copper grades that was compounded by delays in underground development during the period. As a result, a higher portion of ore was mined from lower-grade stopes than planned, resulting in average processed copper grades of 1.08% and production of 8,091 tonnes after recoveries of approximately 88%. At the same time, we benefited from the sale of copper concentrate inventories carried over from the fourth quarter, resulting in copper tonnes sold being nearly 1,400 tonnes higher than tonnes produced during the quarter. With respect to full-year production, we are reaffirming our guidance range of 42,000 to 47,000 tonnes with production expected to be weighted towards the second half of the year. Conversely, our copper C1 cash costs, which averaged $2.30 per pound produced in the quarter, are expected to decrease throughout the year due to projected sequential increases in copper grades and production over the next 3 quarters. As a result, we are reaffirming our full-year cost guidance at Caraiba of $1.80 to $2 per pound. It is worth noting that there is potential for unit cost to improve further as we continue to lock in more favorable concentrate treatment and refining charges than we have assumed in our guidance. Before I pass the call to Makko for a deeper dive into project execution, I will share a few highlights of our first-quarter financial performance. As mentioned, we experienced a fortunate culmination of high copper and gold prices, record production and operating margins at Xavantina, and the sale of copper concentrate inventories carried over from the last year at Caraiba. Collectively, these factors drove solid first-quarter cash flow from operations of $17.2 million and adjusted EBITDA of $43.3 million. I'll now hand the call over to Makko after which Wayne will provide more detail on our first-quarter financial results.

Thank you, and good morning, all. As we turn the corner towards the finish line on the construction phase of the Tucuma project, I want to reiterate what David said and recognize our site leaders, our operational teams and our third-party partners at the Tucuma project for their continued commitment to safety. Since green lighting the Tucuma build, our top priority as an organization has been to deliver the project safely. While we have had many successes at Tucuma over the past few years, I speak for all of us here at Ero and say that our performance on safety is what we are most proud of. When we're looking at our safety record, reaching 97% physical completion this quarter, achieving key commissioning milestones ahead of schedule with a line of sight visibility we now have on our unchanged $310 million capital cost estimate, to put it simply, we are finding a lot to celebrate at Tucuma these days. Looking at where we are at in terms of commissioning and production sequencing for the balance of the year, we have continued to make excellent progress towards the start of operations. Following the successful completion and ramp-up of our crushing, screening and conveyance systems earlier this year, we've been able to focus all of our attention on the systematic completion of our milling, flotation and filtration systems in order to commence integrated commissioning. With the recent completion of our freshwater intake system as well as the conclusion of major mechanical and subcomponent commissioning steps in the process plant, we expect to initiate integrated commissioning just prior to the end of the quarter. On the mining side at Tucuma, which is already in full operational mode, our cumulative operational performance remains well ahead of schedule despite strong rains during the second half of March. We ended Q1 with approximately 36,000 tonnes of ore in a run-of-mine stockpile and an additional 160,000 tonnes of stripped ore in the mine ready to be blasted. With the rainy season well behind us, a significant amount of sulfide ore available for processing and new commissioning milestones being reached on a daily basis, we are in an excellent position to achieve first concentrate production in early Q3 and reach commercial production, which we define as 80% of nameplate capacity, by the end of the third quarter. At our Caraiba Operations, while the quarter had slightly lower grade mined and processed versus our expectations due to development delays in the Pilar Mine, since the beginning of the second quarter, we have made strong progress on development and production and we are reaffirming our full-year production guidance. As it relates to the construction of the new shaft for the Pilar Mine, also at our Caraiba Operations, shaft sinking continues to progress as planned and we remain on track to achieve our target depth of approximately 600 meters by year-end. In terms of specific milestones on this project, it's worth highlighting that we successfully and safely concluded the second and longest raisebore segment of the shaft at the end of April. At its finished length of approximately 720 meters, the segment has set a new record for the longest raisebore ever completed in Brazil. Underground development and infrastructure installations required for the ore handling system of the shaft, including our pressure chamber, conveyance levels, as well as ore and waste silos are progressing on schedule, and the project continues to remain on track for shaft handover to operations in Q4 of 2026. Lastly, we had an incredibly strong start at our Xavantina Operations during the first quarter, which has been well covered by David. If there are any specific questions on the progress at Xavantina, I'll be happy to address those in our management Q&A. I will now turn the call to Wayne to discuss our financial results.

Thank you, Makko. As David highlighted, our financial results for the quarter reflected several positive factors. These included rising copper and gold prices, record production and margins at the Xavantina Operations and the sale of copper concentrate inventories carried over from the fourth quarter at the Caraiba Operations. In addition, a favorable move in foreign exchange led to a realized gain on our foreign exchange hedges of $2.1 million that contributed to first quarter cash flows from operations of $17.2 million and adjusted net income attributable to the owners of the company of $16.8 million or $0.16 per share on a diluted basis. Subsequent to quarter end, we elected to take advantage of another favorable move in the exchange rate and added a layer of zero-cost collars for the second half of this year with floor and ceiling rates of $5.15 and $5.62, respectively. The real has since strengthened against the U.S. dollar, falling back to a rate of approximately $5.05 yesterday. As at the end of last month, the total notional value of our foreign exchange derivative position for the remainder of 2024, including both the zero-cost collars and forward contracts was a little over $250 million. These hedges cover nearly all of our real-denominated operating expenses and the majority of our major project capital expenditures for the remainder of the year and have a weighted average floor and ceiling of $5.02 and $5.38, respectively. Of the total hedge program, approximately $65 million is allocated for major project capital expenditures with a weighted average floor and ceiling of $5.10 and $5.23, respectively. The quarter saw a significant decrease in our capital expenditures with construction winding down as we approach initial production. As a result, we ended the quarter with a total liquidity position of $156.7 million, including $51.7 million in cash and cash equivalents plus $105 million of undrawn availability under our senior secured revolving credit facility. We have also entered into a $50 million non-priced copper prepayment facility subsequent to the quarter end. This facility provides cost-effective capital in a favorable physical copper market, particularly in light of persistently higher interest rates. The repayment of this facility is structured over 27 equal monthly installments of 272 metric tons of copper beginning in October 2024. Should the market value of the copper delivered in any given month exceed $2.1 million, we will receive a repayment for the excess amount. I will now pass the call back to David to share some closing thoughts.

Thank you, Wayne, and thank you, everybody who joined the call today. Before we proceed to the Q&A session, I want to extend my deepest gratitude to our teams in Brazil and Canada for their continued commitment and hard work in executing on both our operating plan and our organic growth strategy. I look forward to our third quarter earnings call when I expect to discuss the ramp-up of production underway at Tucuma. Now I will hand the call back to the operator to open the line for questions.

Today's first question is from Gordon Lawson with Paradigm Capital.

So starting with Caraiba, is it reasonable to model nearly 4 million tons of throughput for 2024, and what average grade would you expect for the remainder of the year?

Great question. Thank you for that. Yes, if you consider what we achieved in the first quarter regarding our production schedule for the year, we expect our copper production to be weighted towards the second half. It seems likely that we will fall slightly short of the 4 million-ton target, as our initial guidance was just below that due to the ramp-up of our mill expansion circuit in the first quarter. We also expect that the grade will be somewhat higher throughout the year, estimated to be around 1.2% to 1.3% for the full year.

Okay. Okay. Yes, that works out here. And just looking ahead, so there's been a lot of significant success on exploration at Caraiba and reading what's going on at Pilar right now, so I'm just curious if there are other expansions being evaluated further down the pipeline.

Yes. We do have, and we've been open with regards to a number of ore bodies that we've identified in the northern part of the project and the property. We are evaluating longer-term and nothing imminent, but certainly longer-term opportunities in order to try and extract value from those ore bodies, which may include longer-term the potential to construct a second concentrated plant in the north, but that's very preliminary right now. Where we stand overall with regards to our operations at Caraiba is, the focus now is purely on getting the shaft completed, which will allow us to then access very high-grade material in the deepening project and then further take us back to the position that we've always wanted to be and have been as one of the lower-cost producers of copper in the world by accessing these high-grade ore bodies to depth in the Pilar Mine.

The next question comes from Orest Wowkodaw with Scotiabank.

Questions for Makko around the Tucuma ramp-up and completion here. I mean you're guiding to a start-up in early July, so call it 2 months from now. What would you consider to be sort of the big critical path items that need to happen in order to achieve that time line?

Yes, great question, Orest. If you break it down and consider what needs to be completed between now and July, I would say we are in the final stretch. This includes electrical installations, automation, and some minor piping such as compressed air and reagent pipelines. From a critical path perspective, we are really down to the final items, and we continue to make strong progress on these initiatives. Our focus over the next two months will be on non-critical path piping, the automation circuits we are installing, electrical cabling, and instrumentation.

Just to add to that, I mean, where we are right now, we are already running water through the filtration. That means through the flotation circuits and the Jameson Cells. We're in the process of turning the mill on. As we've previously put in, all dry commissioning has been completed, and we have all now sitting on the run-of-mine stockpile. And so really, as Makko has pointed out there, we're really down to the final little straws here. We're looking forward to turning on the tailings filtration plant over the course of the next couple of weeks. And then moving as aggressively as we can towards full running of the wet circuit over the course of the next 3 weeks.

Just following up, I mean, earlier, you mentioned that you hope to exit Q3, I think I heard it at 80% of throughput. I mean that's a pretty quick ramp-up if we're talking to start-up in early July. Like what are you seeing that gives you that kind of confidence in terms of compressed ramp-up schedule?

Yes, I believe the situation isn't as compressed as it might seem. We've actually set ourselves up for a solid start in early Q3. Additionally, we are currently commissioning our independent systems daily. For instance, our flotation system, as Dave mentioned, along with our Jameson Cell and filtration systems are functioning independently. There is a lot of activity underway that reassures us about our timeline. However, if you examine our overall ramp-up schedule, we have a fairly typical ramp-up rate to reach 80%. We are not expecting to hit 100% nameplate capacity for about nine months as part of our total ramp-up curve. In other words, during the initial phase, I believe we are well positioned to reach that 80% nameplate. The ramp-up will obviously continue over that nine-month period. However, I am confident that our ramp-up curve aligns well with industry standards based on many projects I've reviewed.

Okay. And just a final question, if I could. I remember the current mine plan for Tucuma obviously has very high copper production in the first 2 years or so. Then I'm wondering if you're seeing anything on the exploration side that could potentially extend that high-grade, sort of high production level for longer, beyond 2026 and maybe what the timeline might be to see an updated mine plan around that?

Thank you, Orest. Good question. We currently have a small underground resource located below the pit, which is very high-grade, similar to what we've mined in the initial years. Mike Richard, our Chief Geologist, and his team are preparing to bring the drilling rigs back to explore the underground extension. We aim to supplement the high-grade material from the underground operation as we see a decline in higher-grade output from the open pit. We have a timeframe of 18 months to 2 years to achieve this, and more clarity on the mine plan will emerge during that period. This is an ongoing process for Tucuma, and we have to manage what we can handle at once. The rigs are expected to return in the third or fourth quarter to drill additional underground resources for potential mining. I see this as a similar scale to other projects we have worked on previously, which will allow us to supplement the grades from the underground as we progress.

The next question comes from Craig Hutchison with TD Bank.

Just a question on Caraiba with regards to the comment that there were some delays in underground development required to access the scheduled high-grade stopes. Is that now behind you guys? Or are there some issues that might creep into Q2 as well?

Yes. Thanks, Craig. We do not anticipate those issues affecting Q2. Compared to our initial expectations for development in some of the high-grade stopes, we identified various contributing factors, mainly related to equipment availability. As I mentioned during the call, we've observed strong development rates and production coming out of Q1 and early Q2, so we believe that those challenges are mostly resolved now.

In your opening remarks, you mentioned that you've observed some favorable concentrate off-trade terms. Can you elaborate on those terms and what your pricing exposure for offtake will be in the latter half of this year?

Yes. Thanks, Craig. Yes. So we've been taking advantage of what a lot of people know in the marketplace as the favorable TC/RC terms. We've entered into 2 contracts so far. They will be kicking in from May onwards, this month onwards, 2-year contracts for about 1/3 of our production. Obviously, we don't want to go into too much detail because it's unfair to all parties involved. But in general, the terms are in the low teens. We are looking to strengthen that portfolio right now with regards to an additional tender that we're about to enter into with various suppliers, and we're waiting to receive those tender offers over the course of the next couple of weeks to further enhance that and increase the total amount that we have exposed at some of these lower TC/RC rates. But on an overall basis, 2 years for about 1/3 of our production beginning in May in the low teens, if you look to model.

Maybe one last question for me. I know you guys are excited about the Furnas project. Any kind of color in terms of when you guys will be able to finalize a definitive agreement?

Yes. We're working with Deepk Hundal, our Chief Counsel, who is currently addressing the final details of our agreement with Vale. This agreement is close to being signed, and we want to ensure that it is completed accurately. It serves as a framework for our future collaborations with Vale, so it’s important for both parties to get it right. I’m pleased to announce that we have signed a core sharing agreement with Vale, allowing us to transfer all core samples for the Furnas project into the core shack. This enables us to quickly proceed with compiling a 43-101 compliant mineral reassessment, which we aim to share with the market by the third quarter of this year.

The next question comes from Stefan Ioannou with Cormark Securities.

Just wondering with the positive grade reconciliation we're continuing to see at Xavantina, is there any thought of maybe going in and doing some additional drilling ahead of production to really nail down your mine plan? Or I mean, I appreciate it's vein. So maybe is the plan just to continue mining and then get what you get?

Yes, that's a great question, Stefan. The uniqueness of the Xavantina and our current position is significant. We mentioned last quarter the restrictions on search ellipses, so we need to review how much infill drilling will be necessary. For now, we're focusing on development ahead of mining, as Dave mentioned. Where we have channel sampling and a high level of confidence in the ongoing grades, we've incorporated that into our full-year production results. Overall, looking back several years, the reconciliation between our long-term model and short-term results has been very strong. Considering our current situation and the promising reconciliation we expect in the next few levels, I don't believe additional drilling costs are necessary at this point.

I think, Stefan, just to add to that, I mean, the zone that we're encountering here is not particularly wide. And so it's fortuitous that we've hit it. We've got 5 or 6 holes into them. As Makko said, the constraint on top cutting and drilling is around holes. We have been conservative in this area. And I think it's the best thing just to continue to do and just take it as a happy opportunity right now for as long as it continues to give it to us. Certainly, if we're in a situation next year and we continue to see this, we may have to rethink that strategy. But right now, as Makko said, it's really not worth trying to drill out this zone and trying to add into our resource or reserve estimate.

And maybe one other one for me, just on the gold exploration with Ero. I mean, obviously, nickel is still something we always think about in the background. Is there any more updates there? I know there was talk of still trying to secure some property positions before you sort of really get into even a hard run. Is that still the case? Or...

Yes. Yes. We continue to do work on nickel albeit not at the same rate as we had done early last year. I've asked the team to take a step back and do them because, as I've mentioned in the past over the last 6 to 8 months, the nickel opportunity has got a lot bigger than we ever thought it would become. And with that, I think we have to be cognizant and disciplined with regards to how we go about evaluating all of these target areas. A lot of this is predicated right now with regards to the government auction process. I'm happy to say the government has given us notification that they will imminently start that process, and we hope to see that and be able to give the marketplace more insights into how the auction has gone, et cetera, in the third quarter. But certainly, the opportunity set on nickel sulfide exploration is significant, and we just need to be super smart with regards to how we approach this right now because I think you could really go and blow your brains out in terms of trying to attack this too quickly. And so Mike and his team are evaluating a number of different things with regards to surface geochemistry work, with regards to ground-based EM analysis, et cetera, to see if there are ways that we can shortcut this process as opposed to having to drill significant amounts of holes to try and identify opportunities in nickel sulfide. So very much a work in progress and certainly, one that we continue to evaluate and we'll continue to work on. But right now, the priority remains for us is Tucuma. When Tucuma is done, obviously, Furnas is such a big growth opportunity for us that it really provides a great future for us as a copper mining company. And as and if nickel continues to develop, we will continue to follow it on a need basis.

The next question comes from Connor Mackay with Ventum Financial.

Just along the same vein as the first question asked here. I was just wondering approximately when are you expecting to hit that full 4.2 million ton per annum run rate at Caraiba?

Yes. Great question. Look, I think for us at Caraiba, obviously, we completed the mill expansion. We have Honeypot in production in the upper levels of the mine I would classify as the whole complex. The deepening is in production as well. So those increased production rates up to 4.2 will be closed this year when the dust settles. But in terms of getting over 4 million tons, that's really going to be a post-shaft completion when we have the 2 mine systems completed at Pilar Mine. So as I said, if you look at our throughput estimate for this year, it's going to be up significantly relative to prior years. But achieving the full mill capacity, as I said, is really longer term when we have those shafts operating.

Awesome. And then just one more quick one on Tucuma with the transition into operations from construction and getting into the first full year of production next year, what kind of levels of sustaining capital should we be expecting, particularly in relationship to the most recent technical report, which I imagine there's some level of inflation that needs to be factored in there at this point?

Yes. Look, in the first year of operations, I wouldn't anticipate much in the way of sustained capital at all really. I mean, obviously, we will be continuing to do some stripping during the year. But if you look at our strip ratio in the first year is still really low. So I would anticipate that most of that is expensed in the first year. So we don't get into meaningful pushbacks until later on in the mine life, but we'll incur additional sustaining costs related to stripping. So it's going to be a small amount. I don't have the exact number off the top of my head here. We can follow up in a call afterward to give you the specifics, but it's going to be very small.

Thank you. This concludes the question-and-answer session. I would like to turn the conference back over to David Strang for any closing remarks.

Thank you, operator. And again, thanks to everybody for coming on the call. We really appreciate everybody's interest in our company. We look forward to talking to you all again in August where we hope to be having more detailed and granular conversations regarding the exact day we will actually hit commercial production, and we'll be happily talking to you about how Tucuma is coming on schedule and the concentrate sales that we've started to make at that time. So thanks again, everybody, and we look forward to talking to you again, as I said, in August. Enjoy your summer. Thank you.

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