Thank you for standing by. This is the conference operator. Welcome to the Ero Copper Third Quarter 2024 Operating and Financial Results Conference Call. As a reminder, all participants are in listen-only mode, and the conference is being recorded. After the presentation, there will be an opportunity to ask questions. [Operator Instructions]. 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 third 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 three and nine months ended September 30, 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 US dollars. I will now pass the call over to David Strang.

Thank you, Courtney. We appreciate that this is a busy week, especially with the news surrounding the US Presidential Election. So thank you all for taking the time to join us today. Before diving into our third quarter results, I want to take a moment to discuss the leadership succession announcement we made yesterday. This transition is something we've been thoughtfully planning over the last two years, beginning with Noel’s decision to step down as Executive Chairman in January of 2023. Noel’s contribution have been instrumental in shaping Ero Copper from its early stages into the successful high-growth copper producer, we are today, and I am immensely grateful to have him taken this unimagined journey with him over the past eight years. As I step into the role of Executive Chairman, I'm excited about what lies ahead for Ero. I remain fully committed to our long-term success and look forward to continuing to support our growth in this new capacity. With Makko assuming day-to-day leadership of Ero’s President and CEO, we are in incredibly capable hands. Makko has demonstrated exceptional leadership as our Chief Operating Officer, Championing, Safety advancing our strategic growth initiatives, including the successful construction of Tucumã and strengthening our culture of accountability. I have absolute confidence in his ability to lead Ero into this next chapter. I am also pleased that Makko will have the full support of Gelson Batista, who joined us in September in anticipation of this transition. Gelson brings a wealth of experience from his 25 years in the mining industry, most recently serving as Chief Operating Officer of ArcelorMittal's mining division. His expertise will be invaluable as we continue to strengthen our operations and execute on our growth strategy. With that, let's move to our third quarter operating and financial results. This past…

Thank you, Dave, and good morning, everyone. Before commenting on our third quarter operating performance, I want to start by saying that I'm truly honored to have been appointed the next CEO of Ero Copper. Having been with Ero since before our IPO, I take immense pride in what we've been able to achieve together over the past 8 years. We have a strong underlying asset base an outstanding portfolio of growth projects in Brazil, a proven mine building team and an extremely dedicated global workforce. I'm excited deeply committed to continuing to serve our shareholders and to lead the sustainable execution of Ero's next stage of growth. Switching gears back to our operations and starting at Tucama, as David mentioned, we navigated a highly dynamic ramp-up environment over the past few months due to intermittent voltage variability that was compounded by a major windstorm-related disruption in early October. While these obstacles created some setbacks in the pace of overall ramp-up progress following a very successful July and August, I'm proud of the resilience of our engineering, project and operational teams on site, who in a joint effort with other major industrial users in the region were able to safely restore power to site in just 10 days. In parallel, over the past few weeks, we work closely with our automation partners and our broader engineering group to adjust our mill drive to accommodate this voltage variability. I'm optimistic about the progress we are seeing and we've been able to achieve and sustain higher throughput levels at Tucama, since the implementation of this solution. It is worth mentioning that our recoveries and concentrate grades have continued to remain at or above design levels. During the second half of October, following restoration of power to site, we produced more copper from…

Thank you, Makko. As Dave highlighted, our third quarter financial results benefited from an expansion in operating margins driven by a significant decrease in unit costs at Caraiba and higher realized gold prices at Xavantina. This resulted in higher adjusted earnings before interest tax depreciation and amortization of $62.2 million and adjusted net income attributable to owners of the company $27.6 million, or $0.27 per share on a fully diluted basis. During the quarter, we took advantage of the rally in gold prices by opportunistically entering into zero cost collars on 2,500 ounces of gold per month from January 2025 to December 2025. These contracts establish a floor price of $2,200 per ounce and a ceiling price of $3,425 per ounce, allowing us to participate in gold price increases up to a level that is over 20% above the all-time high reached in October 2024. The total hedge volume of 30,000 ounces represents just over 50% of our projected 2025 gold production at our Xavantina operation. With respect to our foreign exchange hedge program, we reported an unrealized gain of $9.8 million and a realized loss of $3.4 million for the quarter. The total notional value of our foreign exchange derivative position through quarter end was approximately $327 million, consisting primarily of $315 million in zero-cost collars with a weighted average floor and ceiling of BRL 523 [ph] and BRL 608 [ph] per U.S. dollar, respectively, is extending through the end of 2025. Our liquidity position at the end of the quarter remained strong at approximately $125 million. As Dave mentioned earlier, we believe we have passed a cash flow inflection point in October and expect our liquidity position to meaningfully increase its production and concentrate sales at Tucama ramp-up. I'll now pass the call back to David to share some closing thoughts.

Thank you, Wayne, and thank you, everybody, for joining us today. Before I move into the Q&A session, I want to take a moment to express my gratitude to the entire Ero team. As I continue to be part of Ero's growth journey, I am more than excited than ever about what lies ahead for us. I want to extend my best wishes to Makko and Gelson as they step into their new roles. I have full confidence they will exceed all expectations. I'd also like to thank Noel for his dedication and partnership over the past eight years. I'm incredibly proud of what we have achieved together, and I wish him the best in his next chapter of his life. Now I'll hand the call back to the operator open the line for questions.

We will now begin the question-and-answer session. [Operator Instructions] Our first question comes from Ralph Profiti with Eight Capital.

Thanks operator. First off, David, Makko and Gelson, I offer my congratulations on the appointments, and Noel, congratulations on his retirement. Firstly, on Caraíba, if I may. It sounds like the contractor issues are going to have sort of a knock-on effect on dilution versus plan and reconciliation versus plan. I'm wondering if that's kind of what you meant by, sort of, the underperformance in the mine plan, not only in Q4, but sort of the first part of 2025. And if you can of help me understand kind of what degree versus plan are we impacting dilution and reconciliation?

Yes. Thanks. Good question. And just to clarify, the issue with third-party development doesn't have to do with dilution or any modifying factors for the stopes. It more has to do with our ability to increase operational flexibility and access additional high-grade stopes that we had hoped would be in the plan for the second half of this year. Those are being shifted out into the first half of next year. And obviously, there's a knock on effect temp -- the entire plan with the underperformance of those development rates. So just to be clear, no impact on dilution, reconciliations or anything with respect to the stopes that are in the plan. It more has to do with the access and timing of getting to those stopes and mining that safely and successfully.

Okay. Got you. Yes. Thank you for that clarification. And just coming to Tucama and Power. In the prepared comments, it sounded like the trips and these oscillations were happening at higher throughput. And I was just wondering, Tucama at the entire allotment of its 25 megawatts on the grid at the time of this disruption. And the reason I'm asking is whether or not these are sort of structural and systemic issues that perhaps require capital. And as part of your investigation happening with the public utility and could there be some capital needed to ensure long-term reliability of the system?

It's a really, really good question. With respect to the power grid and what is being done, it's a little bit more complicated in terms of how the whole power grid works up in Pará because there are three separate power providers. Our power provided ties into another network that -- on which this oscillation issue occurs. Frankly, we became aware of it once through our partners at Vale Base Metals once the Onca Puma mine came back from maintenance and started drawing power back from increased power from the grid. The good news is with respect to that is this is a situation that Vale had been dealing with historically. They have been able to put in systems in their own operations with respect to dealing with this issue. We have worked with our contractor, ABB and working on the solution in and around. And for us, it really only affects our mill. It does not affect the rest of the operations. And so with regards to the mill, we have worked with them on software updates with regards to that, but we're not going to rest on that. Similar to Onca Puma and some of the Vale operations are put in place. We are looking at putting another solution in place. The capital cost on these things is not excessive, it's a small amount of money, approximately $1 million with regards to putting one of these systems in, and I can leave it to Makko to talk more broadly with regards to what that system looks like and how it performs.

Yes. It's a good question. I think the main thing to take away from it is that the timing of the voltage oscillations that we experienced, I think were coincident although we're still working with our increased ramp-up to understand that. The solution itself, as Dave mentioned, two things were done. We immediately started engineering a contingency plan for a longer-term installation of a series transformer that allow us to accommodate that voltage volatility at our substation. But in parallel, working with ABB Engineering groups, we implemented the solution our mill to accommodate the variability there. So I'd say the engineering for the long-term solution has been in progress. As I said, at this stage, we view that as a contingency plan, not required based on what we've seen over the last week. But obviously, we're going to continue to monitor that and evaluate the implementation of that solution. I think the main message to take over in this call is that the permanent fix, if required, it's not a significant investment. It's around $1 million.

Got you. Okay. Yes. helpful answers. Thanks very much.

And then and the next question comes from Guilherme Rosito with Bank of America. Please go ahead. Q – Guilherme Rosito: Hi. Thank you. Good morning, everyone. First, I'd like to also congratulate Dave on your journey and wish you best of luck in your new challenges. And also Makko, wish you best of success in your new role. So my first question is on Caraiba. Just wonder if you could put a bit more detail of what you guys are seeing in this new guidance, the top range is where you're targeting then have some room to maybe still have some underperformance and still meet guidance? Or are you targeting the mid of the guidance, there is an upside risk to the top? Then into 2025, when you talk about underperforming first half, should we expect something on the lines of top end of the guidance? And just to understand, what is the structure of what's going on there? And what is circumstantial in terms of the contractor delays that we can look to the coming years before the shop season [ph]? And my second is to Wayne. I completely agree that you had a time of inflection in terms of cash generation, especially as Tucama reserve and your CapEx goes down and then you start generate a lot of cash. So the question is, where's that cash going? What are your priorities in terms of capital allocation, just given the considerable underperformance of the stock recently, does it make sense to open a buyback program, which would you rather pay dividends or would you rather take on your leverage first and think about that? Just trying to understand whether what you're thinking about it. Thank you.

Yes. So great question. I'll take the first part of that and there was a few component parts of the question. So if I miss anything, just feel free to jump back in and let me know. But I think the primary question was on what's systemic versus structural or temporary in nature. I think truly, the development delays that we're seeing, we see as a moment in time in terms of our ability to have enough flexibility in the Pilar mine to continue to access high-grade stopes. So we see that impacting, as Dave mentioned in the prepared remarks, we see that impacting, let's say, the first half of 2025. It's going to be a few quarters to get things back on track there. But overall, we're not seeing a major structural change in terms of the production volumes that we have over the next few years from Caraiba complex. Together, as I said, obviously, it's impacting this year because of that underperformance relative to our expectations. And we see that impacting in the next few quarters. But by the second half of 2025, I think it's fair to say that we expect to be back in a good position with respect to operating flexibility around these high-grade stopes. That will be aided by the efforts of a second third-party contractor that we're bringing on board. I think that was probably covered a few of the different questions that were asked. But maybe before we get into capital allocation, maybe just pause there and see if there's any questions on the operating side that weren't answered. Q – Guilherme Rosito: No, I think that was great, Marco. And just one thing to make it clear. When you guys look at the guidance this year, is the top end where you guys are targeting and then have some room now? Or are you targeting the middle of the range and then have some upside in reaching the top end...

Yeah. Look, it's a great question. I mean, obviously, we're -- we've got a few months left in the year here. I think we gave ourselves a bit of room on production at Caribou. But I don't want to -- it's a very narrow range at this point, so I prefer not to comment on whether we're forecasting to be at the top end or bottom end.

Let me just add in. We've just gone through October. On the revised plan, the team is a little better than what the plan had forecast. So Makko doesn't want to go and the hesitancy is just making sure that we don't get too far over our skis. We're certainly -- with regards to the plan that Gelson put in place since he's arrived in terms of getting us back to where we need to be. October was better than what we expected. Let's see how November goes. But this is all about getting the team to get back on track start progressing every month and start keep improving. We've put in some conservative assumptions within this plan. Obviously, from our perspective, as senior leaders of the company, we'd like the team to beat the plan. And so let's see how we're going. October was a good start. Q – Guilherme Rosito: Capital allocation.

Yeah. And on the capital allocation question, Guilherme, it's -- obviously, we -- the first priority will be to pay back the revolver that we have outstanding. I think once we are comfortable that Tucuma has hit commercial production is running smoothly in 2025, then we can start having a more fruitful discussion around how best to handle the excess cash flow that we expect to produce. I think that's a discussion that is always robust and continually happens at our Board. So I think next year will be at a point where we start to sort of formulate some plans on how best to start returning some of the cash to shareholders. Q – Guilherme Rosito: Great. Thank you very much guys.

And the next question comes from Connor Mackay with Ventum Financial. Please go ahead.

Thanks, operator, and I echo the comments of congratulations there for Dave, Makko and the rest of the team on your new appointments. Just wondering at Pilar, what are the cost implications you guys are anticipating of adding the second mining contractor? Is that going to impact long-term sustaining capital or operating costs going forward?

It's a great question, Connor. I think it's important to note with respect to third-party contractors that bringing someone on board in 2025 was always part of the plan. We obviously accelerated that into the second half of this year in response to some of the challenges we had in the first quarter. So it's really -- it's just a pull forward of that plan. So when looking at our longer-term outlook and plans for the company, we always had a development contractor in place starting in 2025 to increase the rate of development. We've had a third-party development contractor, in fact, the same third-party development contractor operating successfully throughout our operations for the last several years. So this isn't something new to us. And as I said, it was always part of the operating plan. The idea with the second third party contractor isn't so much to increase the rate of development versus what we have planned. It's more to distribute the load as a risk mitigation measure more than anything else.

Got it. Thank you. Tucama, so I assume with the comments surrounding targeting the upper end of 2025 guidance, production guidance out of Tucama. You're fairly confident that commercial production is within reach in the near future, probably late this year or early next year if I'm reading that correctly?

Yes. So let's be clear. Where we are right now, and we had to make sure everybody understood with regards to what we said, our preliminary work that we're doing right now is showing exactly what we said with regards to general guidance for next year. At the moment, you are correct. We are working. The mill is now in continuous operation that we are not seeing any voltage shutdowns of the mill. Makko and the team are now slowly ramping up that mill to commercial production levels. And as I anticipated, hope that we will be at commercial production within the next couple of months. It may slip into early 2025. Our hope is it's not. That's why we are using terminology like preliminary in general at this stage. Once we are better suited, once we've got through the next month with continuous operations and as we said, continuing to ramp up through commercial production levels, then we'll be in a much better position to be able to have a more fruitful conversation with everybody regarding that. And that will dictate into our guidance that we will release in January of next year. But as it stands right now, based upon the runway we see going forward here, what we see is there's no reason to change our general guidance for next year.

Got it. Appreciate the clarity there. Thank you. That’s all for me.

And the next question comes from Roald Ross with Clarksons Securities. Please go ahead.

Yes. Good morning, guys. Congrats on the quarter and congrats on progress with ramping up. So my first question is on Caraiba. I'm just curious if you can provide some color on the cash cost into the next year after having reach this low level?

Yes. Look, I think from a cash cost perspective, there's a couple of things that are creating some good tailwinds for us. And again, I mentioned this last quarter, although it didn't come up this quarter. In the early last year, we started what we call our full potential program. We've seen the benefits of that quarter-on-quarter. And so we're continuing to get supplier costs come down. I would say, specific to Q3, we started to see the full benefit of improved treatment refining charges, specifically related to, obviously, the overall treatment and refining charges are coming down, as David mentioned. But I think it's important to note that the gold price strength continued to benefit us pretty significantly in Q3. And we also saw a weakening of the BRL during the quarter, which if you follow the Brazilian reals here over the last 24, 48 hours, has continued to be in a great spot for us in terms of improving margins relative to our expectations early in the year when we put our budget together. So I would say, major tailwinds that we're continuing to experience, obviously, the TCRCs, the strength of the gold price and the weakening of the BRL, overall tailwinds we expect to continue here for the next couple months.

Great. Thank you. And also on the realized copper price, it seems like for this quarter that the discount looking at the 3 months LME is a bit bigger compared to last quarters. Is that something to comment on? Or is it just a coincidence? Or should we sort of think that this discount could be also this wide going forward?

No. Look, I mean, we had lots of commentary on previous calls about this. Really, if you look at Q3, the copper price did slide in Q3, and so all of that is often just driven around when we ship concentrate. We're not huge producer in terms of volume compared to some of our peers. So a lot of it is driven by the timing of shipments. And simply, when you can't take a simple mathematic average, when our shipments, the timing of our shipments does drive that. So, last quarter, it was a little higher than it was the quarter before. Obviously, the quarter before, we saw a very significantly strengthening copper price in Q2. I would suspect that most copper of our peers had a very tight range on their realized product, but that's all it is. Nothing significant.

Yes. If you look at Q2, the LME average price was 4.42, Q3, the average LME price was 4.17, so that's why you would see that change in the realized price is related to directly the underlying metal price offset a small amount by changes in the gold price over the same period of time.

Okay. Great. Makes sense. And lastly for Tucama, could you give us some color on the sustaining CapEx going forward as you reach nameplate capacity and everything is going as expected?

Yes. Look, I don't think it's appropriate at this point. We're obviously putting together our plans for next year with respect to seeing any capital. We don't see a meaningful variation from what we put on the past in terms of seeing capital. Obviously, costs have increased relative to when we put out the feasibility study just generally in the sector. So I think that's probably a fair comment. But we're -- I'm going to hold comment on that until we put out our formal guidance in January. We're still focused right now on our ramp up and getting to the commercial production level. So, I suggest we revisit that in January with our full year guidance for '25, because we'll have, again, put some clarity around what sustained CapEx is going to be. I expect it to be fairly low in the first year of production. Obviously, we don't have a lot of -- it's a brand-new plant. That will increase a bit over time.

Okay. Great. Appreciate that. Thank you.

And the next question comes from Dalton Baretto with Canaccord. Please go ahead.

Thanks operator. Good morning, guys. I'm a little surprised to see all these operating challenges in Q3, given that we were just on site in the second week of September. I appreciate all the color that's been given on the call so far. But it's still a little bit unclear to me at Caraiba, what the root cause of the productivity issue with the contractor is. I mean is this a new contractor? Was there something temporary that happened? Or is this more of a structural thing? And so I'm just wondering if you can comment on that. And then maybe as you're caught up with the second contractor mid-2025, whether you think it's sustainable on a go-forward basis at that point in time? Thanks.

Yes. Look, it's a great question, Dalton. And I think really what you're looking at. If I go back to -- I think when we're talking about underperformance it's relative to the expectation and the performance against the contract we signed. If I go -- if I look at the curve of weekly increases, mobilization of equipment, mobilization and training of people, those were all behind. So when I look over the past couple of weeks, I'd say the development rates that the contractor’s achieving are in line with the full mobilization, but that mobilization took much longer than we anticipated, and largely due to the availability of equipment and resources in Brazil. I think that's a theme probably throughout the sector, but it certainly impacted our contractor's ability to ramp up the development rates. As I said over the past couple of weeks, they've increased their productivity and rates. So I don't see that as a systemic issue or like challenge in the operation itself. It more has to do with the timing and their ability to achieve higher development rates.

Okay. Thanks for that, Makko. And then maybe switching gears to Tucama as well. I think Dave said that you've only just installed that power management system last week. And I'm just wondering, I mean, have you tested it at full capacity and with your sort of regional neighbors running at full capacity yet? How comfortable are you that this is a permanent solution?

Yes. Look, it's a great question, Dalton. We took a couple of weeks to implement the solution. The first phase was to really measure the volatility and variability that we saw, to put it into context, the power arriving on-site the 138-kilovolt line, we see a millisecond frequencies, voltage dropped to the 120 range. It took a couple of weeks to measure that data fully so that we can engineer the appropriate solution. As Dave mentioned, we put that in last week. We've seen the same levels of variability, that 120 range, and the mill hasn't stopped turning. So I would say that we're really encouraged, although it's only been a week. We've -- if you look at the operating performance since we implemented that solution, we've been able to address the root cause of the issue at our mill. As I mentioned, there's a second solution more expensive around $1 million that we could implement, and we started the engineering of that solution in parallel a few weeks ago. But we're really encouraged by the results we've seen with just the bill adjustment that we've done to-date.

Dalton, I know I'm going to see you tomorrow, but just -- Makko's just highlighted something I think we need to clarify. These voltage interruptions are generally 0.7% of a millisecond. So these aren't voltage fluctuations that sit there for minutes or half an hour or hour, they are literally very small frequencies. In fact, when we first brought it up with the power provider, they said there wasn't an issue on the line, because their measuring equipment couldn't measure that volatility. The issue with regards to it was -- is the software package that was managing our mill, motor such that it had built-in safety frequencies with regards to changes and voltage down to that millisecond. So what would happen was, if we encountered one within -- as Makko has pointed to me, 0.7 of a millisecond, the mill would go into standby mode. And then we have to just physically restart it. But the issue with regards to the restart is the whole system would take another 15 minutes to half an hour to get booted up again. And when that would happen over eight times in a day, you can imagine how your continuous ability to operate at your -- so we were able to operate in between these mills shutdowns by the safety equipment at capacity. But when we average out on a continuous basis, it was because the mill would go into a safe mode of the motor. This ABB solution merely extends out that safety margin on the downside with regards to more fluctuations. So what the mill motor will not do now is go into safe mode with regards to a drop in voltage. Still protects it, but a change at the voltage goes up, which we don't see, it's just merely fluctuations of the mill over milliseconds of change with regards to voltage frequency. So we've essentially just desensitized the software package to an extent to be able to allow that when that voltage drop occurs, the mill doesn't go into safe mode.

That's great color, Dave. Thank you. That sounds like more of aching pain type issue as opposed to a more structural issue. I appreciate that.

Correct.

That’s all for me.

Correct.

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

Thanks, operator. Again, thank you, everybody. This is the last time I will be leading one of these. The next quarterly will be Makko's lead. And I thank you, all. For those who have been following us over the last eight years, for the length of time you've put up with me, and for those new people who are following us in the newer times, I look forward to meaning some of you, if I haven't met you before, but certainly supporting Makko in his role of running these quarterly earnings calls in the future. So thanks very much. Enjoy your day. Bye-bye.

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