Speaker #3: Thank you, and thank you to everyone joining us this morning. As we pre-released our 2025 production results and 2026 guidance in early February, I'd like to take a step back here and explain why we believe Ero is extremely well positioned in the current market environment.

Makko DeFilippo: Thank you, Farooq, and thank you to everyone joining us this morning. As we pre-released our 2025 production results and 2026 guidance in early February, I'd like to take a step back here and explain why we believe Ero is extremely well-positioned in the current market environment. Last week, as many of you would have seen, we released our maiden preliminary economic analysis on the Furnas project.

Speaker #3: Last week, as many of you would have seen, we released our maiden preliminary economic analysis on the Furnas project. This was an important milestone for the company and one of our key objectives this year.

Makko DeFilippo: This was an important milestone for the company and one of our key objectives this year. Over the past 18 months, our exploration and engineering work, combined with extensive historical technical programs completed by Vale on the project since the early 2000s, has enabled the design of an integrated open pit and underground mine expected to produce a total of more than 1.2 million tons of copper, 2 million ounces of gold, and 9 million ounces of silver over an initial 24-year mine life.

Speaker #3: Over the past 18 months, our exploration and engineering work, combined with extensive historical technical programs completed by Valley on the project since the early 2000s, has enabled the design of an integrated open-pit and underground mine expected to produce a total of more than 1.2 million tons of copper, 2 million ounces of gold, and 9 million ounces of silver over an initial 24-year mine life.

Speaker #3: Highlighting the quality of Furnas and reinforcing why it is a cornerstone asset in our long-term growth strategy: Over the first 15 years of operation, Furnas is expected to produce approximately 70,000 tons of copper, 111,000 ounces of gold, and more than 500,000 ounces of silver annually at first quartile C1 cash costs of approximately $2.40 per pound of copper produced.

Makko DeFilippo: Highlighting the quality of Furnas and reinforcing why it is a cornerstone asset in our long-term growth strategy, over the first 15 years of operation, Furnas is expected to produce approximately 70,000 tons of copper, 111,000 ounces of gold, and more than 500,000 ounces of silver annually at first quartile C1 cash costs of approximately $0.24 per pound of copper produced. At long term consensus metal prices, the PEA delivers an after-tax NPV of approximately $2 billion and an IRR of more than 27% on $1.3 billion of initial capital. Taken together, these metrics uniquely position Furnas from a capital intensity perspective relative to comparable projects while delivering strong economic outcomes across a wide range of commodity prices. Said differently, we see an exceptional project that is both financiable and buildable.

Speaker #3: At long-term consensus metal prices, the PEA delivers an after-tax NPV of approximately $2 billion, and an IRR of more than 27% on $1.3 billion of initial capital.

Speaker #3: Taken together, these metrics uniquely position Furnas from a capital-intensity perspective relative to comparable projects, while delivering strong economic outcomes across a wide range of commodity prices.

Speaker #3: Said differently, we see an exceptional project that is both financeable and buildable. As strong as it is, the PEA is just a starting point for us, and we are focused on maintaining momentum this year.

Makko DeFilippo: As strong as it is, the PEA is just a starting point for us and we are focused on maintaining momentum this year. In 2026, we plan to complete an additional 50,000 meters of exploration drilling, targeting extensions of high-grade mineralization around planned underground infrastructure. We will also continue pursuing opportunities we see to further strengthen economics, which include the addition of a magnetite recovery circuit to produce a high-grade magnetite concentrate, as well as a gravity pre-concentration stage to enhance gold recoveries. Both initiatives offer potential to further increase by-product revenue, and we are encouraged by the initial results we are seeing. Getting back to what differentiates Ero, we have clearly outlined a great long-term growth project in Furnas, and we are thrilled to be advancing it towards a construction decision over the coming years.

Getting back to what differentiates Ero, we have clearly outlined a great long-term growth project in Furnas, and we are thrilled to be advancing it towards a construction decision over the coming years.

Speaker #3: Perhaps most importantly, the capital required to advance Furnas to that point is expected to remain relatively modest as we continue to advance technical studies, drilling, and permitting work streams.

Makko DeFilippo: Perhaps most importantly, the capital required to advance Furnas to that point is expected to remain relatively modest as we continue to advance technical studies, drilling, and permitting work streams. At the same time, capital spending across our existing operations is projected to decline as we transition out of a multi-year investment phase that included the construction of Tucumã and major investments at Caraíba over the past several years. These investments are either complete or in the case of our new shaft project at Caraíba, are past peak capital spend. As a result, Ero is exiting a major investment cycle with an exceptional long-term growth asset, increasing cash generation capacity, declining consolidated capital requirements, and three operating mines with the right mix of metals at exactly the right time in the commodity price cycle.

Speaker #3: At the same time, capital spending across our existing operations is projected to decline as we transition out of a multi-year investment in the construction of Tucumán and major investments at Cariba over the past several years.

Speaker #3: These investments are either complete or, in the case of our new shaft project at Cariba, are past peak capital spend. As a result, Ero is exiting a major investment cycle with an exceptional long-term growth asset, increasing cash generation capacity, declining consolidated capital requirements, and three operating mines with the right mix of metals at exactly the right time in the commodity price cycle.

Speaker #3: When I look across the broader sector, many companies—including most of our peers—are jumping into major project builds within the next year. We like this dynamic.

Makko DeFilippo: When I look across the broader sector, many companies, including most of our peers, are jumping into major project builds within the next year. We like this dynamic. Switching gears slightly, I do want to touch on our 2025 results and 2026 guidance. I would start by recognizing the resilience and dedication of our teams that worked through a number of challenges to deliver meaningful improvements across the business as the year progressed. These efforts resulted in sequential quarters of improving operational performance, the unlocking of a major new additional value driver for our business at Xavantina. Starting with Caraíba, Q4 represented our strongest operating quarter of the year. Mill throughput reached nearly 1.2 million tons, up 18% compared to Q3 and an all-time record for the operation.

Speaker #3: Switching gears slightly, I do want to touch on our 2025 results and 2026 guidance. And I would start by recognizing the resilience and dedication of our teams that worked through a number of challenges to deliver meaningful improvements across the business as the year progressed.

Speaker #3: These efforts resulted in sequential quarters of improving operational performance, and the unlocking of a major new additional value driver for our business at Gevonchina. Starting with Cariba, Q4 represented our strongest operating quarter of the year.

Speaker #3: Mill throughput reached nearly 1.2 million tons, up 18% compared to Q3, and an all-time record for the operation. This drove copper production up 15% to C1 cash costs of $2.27 per pound.

Makko DeFilippo: This drove copper production 15% higher quarter-on-quarter and contributed to C1 cash costs of $2.27 per pound. At Tucumã, copper production increased more than 22% quarter-on-quarter, representing another record for the operation. Higher process grades helped offset an extended period of unplanned downtime in December, driven by a pull forward of Q1 maintenance for an early mill liner replacement. This pull forward was due to an OEM wear part quality issue that impacted multiple operations in the region, including ours. C1 cash costs in Q4 were $1.75 per pound, which I would note approximately $0.10 of this was attributable to expensing the unamortized portion of the liners.

Speaker #3: At Tucumán, copper production increased more than 22% quarter-on-quarter, representing another record for the operation. Higher process grades helped offset an extended period of unplanned downtime in December, driven by a pull-forward of Q1 maintenance for an early mill liner replacement.

Speaker #3: This pull-forward was due to an OEM wear part quality issue that impacted multiple operations in the region, including ours. C1 cash costs in Q4 were $1.75 per pound, and I would note that approximately $0.10 of this was attributable to expensing the unamortized portion of the liners.

Speaker #3: Turning to Gevonchina, production increased 53% quarter-on-quarter, driven by higher grades and improved throughput as we began to see the benefits of our efforts transitioning the mine to mechanized mining.

Makko DeFilippo: Turning to Xavantina, production increased 53% quarter-over-quarter, driven by higher grades and improved throughput as we began to see the benefits of our efforts transition the mine to mechanized mining. Our gold concentrate program resulted in an incremental 15,000 ounces of gold in Q4. Total gold from Xavantina, including mine production and concentrate shipments, was nearly 20,000 ounces in the quarter and over 50,000 ounces for the full year. Behind these numbers, what makes 2025 one of our best on record, in my opinion, is that our operational teams deliver these results while achieving one of our best years ever in terms of consolidated safety performance. Whatever might be said about 2025, nothing matters to me more than this metric.

Speaker #3: In addition, our gold concentrate program resulted in an incremental 15,000 ounces of gold in Q4 as a result. Total gold from Gevonchina, including mine production and concentrate shipments, was nearly 20,000 ounces in the quarter and over 50,000 ounces for the full year.

Speaker #3: Behind these numbers, what makes 2025 one of our best on record, in my opinion, is that our operational teams delivered these results while achieving one of our best years ever in terms of consolidated safety performance.

Speaker #3: Whatever might be said about 2025, nothing matters to me more than this metric. As I look ahead to 2026, our guidance assumes the operational performance gains we achieved in the fourth quarter are effectively sustained through the year.

Makko DeFilippo: As I look ahead to 2026, our guidance assumes the operational performance gains we achieved in the Q4 are effectively sustained through the year. While we continue to work on opportunities to further improve performance across the business, especially in the second half of this year at Tucumã, these are not reflected in our guidance. At Tucumã, we are well advanced on adding additional tailings filtration equipment this year to unlock additional throughput capacity for this operation. We have equipment being manufactured right now, and if all goes according to plan, we would expect this to benefit the operation in the Q4. As I mentioned, the potential benefits here, as well as the associated capital investment, have not been reflected in our 2026 guidance. This was a deliberate decision for three reasons. First, getting to steady state was important for us this year.

Speaker #3: While we continue to work on opportunities to further improve performance across the business, especially in the second half of this year at Tucumán, these are not reflected in our guidance.

Speaker #3: At Tucumán, we are well advanced on adding additional tailings filtration equipment this year to unlock additional throughput capacity for this operation. We have equipment being manufactured right now, and, if all goes according to plan, we would expect this to benefit the operation in the fourth quarter.

Speaker #3: As I mentioned, the potential benefits here, as well as the associated capital investment, have not been reflected in our 2026 guidance. This was a deliberate decision for three reasons.

Speaker #3: First, guiding to steady state was important for us this year. Second, there is a lot of daylight between now and the fourth quarter, and perhaps most important in the current metal price environment, we expect the payback on this investment to be one to two quarters.

Makko DeFilippo: There is a lot of daylight between now and Q4, and perhaps most important, in the current metal price environment, we expect the payback on this investment to be 1 to 2 quarters. While it is a very important objective and we expect to complete it this year, it will not change our strategy or capital allocation decisions in 2026. At Xavantina, we are investing in our ventilation circuit, mine development, and equipment to increase mine capacity and output. This is a low-hanging, long-term value driver inherent to our business when we look at the available milling capacity we have there. Last but not least, at Caraíba, we are advancing the new shaft project for the Pilar Mine and are pursuing several operational improvement initiatives that we hope to discuss later this year.

Speaker #3: So, while it is a very important objective and we expect to complete it this year, it will not change our strategy or capital allocation decisions in 2026.

Speaker #3: At Gevonchina, we are investing in our ventilation circuit, mine development, and equipment to increase mine capacity and output. This is a low-hanging, long-term value driver inherent to our business when we look at the available milling capacity we have there.

Speaker #3: Last but not least, at Cariba, we are advancing the new shaft project for the Polar Mine and are pursuing several operational improvement initiatives that we hope to discuss later this year.

Speaker #3: To touch briefly on cadence for 2026, we are guiding consolidated copper production of between 67,000 and 70,500 tonnes, to reflect year-over-year growth driven primarily by higher sustained plant throughput at Caraíba and Tucumã, partially offset by lower planned grades.

Makko DeFilippo: To touch briefly on cadence for 2026, we're guiding consolidated copper production of between 67,500 to 77,500 tons. This reflects year-over-year growth, driven primarily by higher sustained plant throughput at Caraíba and Tucumã, partially offset by lower plant grades. Copper production is expected to be weighted towards the second half of the year due to mine sequencing and a modest increase in throughput throughout the year. At Xavantina in 2026, we are guiding mine production of 40,000 to 50,000 ounces. We expect Q1 to be the softest production quarter of the year. This cadence reflects mine sequencing as well as a tie-in of a major ventilation upgrade during the quarter, including the completion of a new raise bore to surface. Production is expected to be weighted towards the second half of the year as a result.

Speaker #3: Copper production is expected to be weighted towards the second half of the year due to mine sequencing and a modest increase in throughput throughout the year.

Speaker #3: At Gevonchina in 2026, we are guiding mine production of 40,000 to 50,000 ounces. We expect Q1 to be the softest production quarter of the year.

Speaker #3: This cadence reflects mine sequencing as well as a tie-in of a major ventilation upgrade during the quarter, including the completion of a new raised board to surface.

Speaker #3: Production is expected to be weighted towards the second half of the year as a result. Gold concentrate sales are expected to continue throughout the year, but we expect that to be relatively modest in Q1 due to the rainy season.

Makko DeFilippo: Gold concentrate sales are expected to continue throughout the year, but we expect that to be relatively modest in Q1 due to the rainy season. For some additional context there, you'd be hard-pressed to find a more simple operation in our portfolio. There are only three steps. We remove the material from stockpile, we then spread it out in the sun to dry, then transport the material for shipment. As you can likely imagine, step two in that process is far less productive during the rainy season. With that, I will turn the call over to Wayne, who will walk through our financial results in more detail.

Speaker #3: For some additional context there, you'd be hard-pressed to find a more simple operation in our portfolio. There are only three steps: we remove the material from stockpile, we then spread it out in the sun to dry, then transport the material for shipment.

Speaker #3: As you can likely imagine, step two in that process is far less productive during the rainy season. With that, I will turn the call over to Wayne, who will walk through our financial results in more detail.

Speaker #2: Thank you, Makko. Our fourth quarter financial results were driven by record copper concentrate sales, a 59% increase in gold doré sales, the commencement of gold concentrate sales, and stronger copper and gold prices during the period.

Wayne Drier: Thank you, Makko. Our Q4 financial results were driven by record copper concentrate sales, a 59% increase in gold doré sales, the commencement of gold concentrate sales, and stronger copper and gold prices during the period. All of these factors drove quarterly revenue to a record $320 million or $143 million higher compared to the Q3. Consolidated C1 copper cash costs per pound were approximately 1.5% higher quarter-on-quarter, with the increase predominantly coming from Tucumã, where we experienced higher transportation demurrage and port costs in the quarter related to the COP30 activities in Pará State. The sudden impact of approximately $0.10 per pound on our Tucumã C1 costs, which were also impacted by the accelerated amortization of the mill liner Makko referenced earlier.

Speaker #2: All of these factors drove quarterly revenue to a record $320 million, or $143 million higher compared to the third quarter. Consolidated C1 copper cash costs per pound were approximately 1.5% higher quarter on quarter, with the increase predominantly coming from Tucumã, where we experienced higher transportation demurrage and port cuts in the quarter related to the COP30 activities in Pará State.

Speaker #2: The sudden impact of approximately $0.10 per pound on our Tucumán C1 costs, which were also impacted by the accelerated amortization of the mill liner Makko referenced earlier.

Speaker #2: Gold C1 cash costs per ounce declined by approximately 29% from the third quarter. As a result, the company delivered stronger operating margins, with adjusted EBITDA growing to $186.7 million in the fourth quarter and $409.7 million for the full year.

Wayne Drier: Gold C1 cash costs per ounce declined by approximately 29% from Q3. As a result, the company delivered stronger operating margins, with adjusted EBITDA growing to $186.7 million in Q4 and $409.7 million for the full year. Adjusted net income attributable to owners of the company was $108.4 million for the quarter and $220.4 million for the year, or $1.04 and $2.12 per share, respectively. Our liquidity position at quarter end stood at $150.4 million, including $105.4 million in cash and cash equivalents and $45 million of undrawn availability under our revolving credit facility.

Speaker #2: Adjusted net income attributable to owners of the company was $108.4 million for the quarter and $220.4 million for the year, or $1.04 and $2.12 per share, respectively.

Speaker #2: Our liquidity position at quarter-end stood at $150.4 million, including $105.4 million in cash and cash equivalents, and $45 million of undrawn availability under our revolving credit facility.

Speaker #2: We continued to deleverage our balance sheet, with net debt declining to approximately $502 million at year-end from $545 million at the end of the third quarter.

Wayne Drier: We continued to deleverage our balance sheet, with net debt declining to approximately $502 million at year-end from $545 million at the end of Q3. Combined with significantly higher 12-month trailing EBITDA, this resulted in a material improvement in our net debt leverage ratio, which decreased to 1.2x at the end of Q4 from 1.9x in Q3 and 2.6x at the end of 2024. With copper and gold production expected to grow in 2026, as well as the additional cash flow from Xavantina's gold concentrate sales, we intend for debt reduction and return to shareholders to be key elements of our midterm capital allocation strategy. At 31 December, we had $155 million drawn on our revolver, which we intend to pay down fully in 2026.

Speaker #2: Combined with significantly higher 12-month trailing EBITDA, this resulted in a material improvement in our net debt leverage ratio, which decreased to 1.2 times at the end of Q4 from 1.9 times in Q3 and 2.6 times at the end of 2024.

Speaker #2: With copper and gold production expected to grow in 2026, as well as the additional cash flow from Shavantina's gold concentrate sales, we intend for debt reduction and return to shareholders to be our allocation strategy.

Speaker #2: At December 31st, we had $155 million drawn on our revolver, which we intend to pay down fully in 2026. We would like to maintain a strong cash position on the balance sheet and target a net debt to EBITDA ratio below 1x ahead of commencing a return of capital program.

Wayne Drier: We would like to maintain a strong cash position on the balance sheet and target a net debt to EBITDA ratio below 1 times ahead of commencing a return of capital program. I'll now pass the call back to Marco for some closing remarks.

Speaker #2: I'll now pass the call back to Makko for some closing remarks.

Speaker #3: Thank you, Wayne. Before we move into the Q&A session, let me recap the three key elements of ERO's value proposition. First, over the past decade, ERO has consistently unlocked value that wasn't fully recognized, often through work supported by strong partners.

Makko DeFilippo: Thank you, Wayne. Before we move into the Q&A session, let me recap the three key elements of Ero's value proposition. First, over the past decade, Ero has consistently unlocked value that wasn't fully recognized, often through work supported by strong partners. Clear examples include our gold concentrate program and our broader partnership with Royal Gold at Xavantina, and more recently, the advancement of the Furnas project with our partner, Vale Base Metals. Second, we've taken a disciplined countercyclical approach to capital allocation, investing in building projects during periods when development activity across the sector was limited. That strategy has positioned Ero favorably relative to our peer group that are now preparing to enter major capital investment phases. Third, Furnas represents a high-quality, long-life asset being advanced with a top-tier partner, and we view it as a compelling cornerstone for Ero's long-term growth.

Speaker #3: Clear examples include our gold concentrate program and our broader partnership with Royal Gold at Gevonchina, and, more recently, the advancement of the Furnace project with our partner Valley Based Metals.

Speaker #3: Second, we've taken a disciplined, countercyclical approach to capital allocation, investing in building projects during periods when development activity across the sector was limited. That strategy has positioned Ero favorably relative to our peer group that are now preparing to enter major capital investment phases.

Speaker #3: Third, Furnace represents a high-quality, long-life asset being advanced with a top-tier partner, and we view it as a compelling cornerstone for Ero's long-term growth.

Speaker #3: With that, I will now turn the call back to the operator to open the line for questions.

Makko DeFilippo: With that, I will now turn the call back to the operator to open the line for questions.

Speaker #4: Thank you. To join the question queue, you may press star, then one on your telephone keypad. You will hear a tone acknowledging your request.

Operator: Thank you. To join the question queue, you may press Star 1 on your telephone keypad. You will hear a tone acknowledging your request. If you're using a speakerphone, please pick up your handset before pressing any keys. To withdraw your question, please press Star 2. First question comes from Orest Wowkodaw with Scotiabank. Please go ahead.

Speaker #4: If you’re using a speakerphone, please pick up your handset before pressing any keys. To withdraw your question, please press star, then two. First question comes from R.S. Rockdale with Scotiabank.

Speaker #4: Please go ahead.

Speaker #5: Hi, good morning. Question around the gold concentrate stockpiles at Gevantina. You haven't issued any guidance for what those volumes could be this year, but with the 15,000 ounces you sold in the fourth quarter, is that a good guide for shipments in periods or quarters where there's no rainy season?

Orest Wowkodaw: Hi, good morning. Question around the gold concentrate stockpiles at Xavantina. You haven't issued any guidance for what those volumes could be this year, but with the 15,000 ounces you sold in Q4, is that a good guide for shipments in periods or quarters where there's no rainy season?

Speaker #3: Yeah, thank you for the question, RS. Obviously, a bit of a tricky situation. Obviously, we came out with initial resource on the 20% of the volume that we were able to sample, so it's difficult for us, as you can imagine, to give exact guidance.

Makko DeFilippo: Yeah. Thank you for the question, Orest. Obviously, a bit of a tricky situation. Obviously, we came out with initial resource on the 20% of the volume that we were able to sample. It's difficult for us, as you can imagine, to give exact guidance. We certainly, you know, expect strong volumes in shipment. I would point to what we achieved in Q4. That was at the tail end of the rainy season. Just for context, the rainy season in Mato Grosso typically starts in November and goes through March, April, depending on the year. You know, part of those sales did occur when the rainy season was started. We're obviously advancing several initiatives on site to increase volumes from there.

Speaker #3: But we certainly expect strong volumes in shipment. I would point to what we achieved in Q4. That was at the tail end of the rainy season, so, just for context, the rainy season in Mato Grosso typically starts in November and goes through March or April, depending on the year.

Speaker #3: And so, part of those sales did occur when the rainy season had started, where obviously we are advancing several initiatives on site to increase volumes from there.

Speaker #3: And as I said at the outset of the call, Q1 is the heart of the rainy season. This has been an exceptionally rainy year in Brazil, as you are probably aware.

Makko DeFilippo: As I said on the outset of the call, you know, Q1 is the heart of the rainy season. This has been an exceptionally rainy year in Brazil, as you are probably aware from some of the news flow and flooding that's happened throughout the country. Therefore we expect, you know, very modest sales in Q1, and then ramp up pretty aggressively Q2, Q3.

Speaker #3: From some of the news flow and flooding that's happened,

Speaker #1: Throughout the country, and therefore we expect, you know, very, very modest sales in Q1, and then ramp up pretty aggressively.

Speaker #1: Q2 , Q3 .

Speaker #2: And in terms of the stockpile itself, have you seen anything that may suggest that the grade for the other 80% of the stockpile would be materially different than what you have sampled?

Orest Wowkodaw: In terms of the stockpile itself, have you seen anything that may suggest that the grade for the other 80% of the stockpile would be materially different than what you have sampled?

Speaker #1: Difficult to say , but nothing , obviously , as we go in the future , we don't have samples there , but to date , nothing that nothing that suggests otherwise

Makko DeFilippo: Difficult to say, Auris, but nothing. Obviously, as we go in the future, we don't have samples there, but to date, nothing that suggests otherwise.

Speaker #2: Okay . Thanks very much

Orest Wowkodaw: Okay. Thanks very much.

Speaker #3: Next question comes from Emerson Vieira with Goldman Sachs. Please go ahead.

Operator: The next question comes from Emerson Vieira with Goldman Sachs. Please go ahead.

Speaker #4: Hello. Good morning. Thank you for taking my questions. I'd like to listen a little bit more on Tacoma's future. Prep issue.

Emerson Vieira: Hello, good morning. Marco Fabro Cabruna. Thanks for taking my questions. I'd like to listen a little bit more on Tucumã's filter press issue. Can you provide us an update here? Have you guys already ordered the mobile filter that it is expected to improve the filter availability? Any update on time could be very helpful. Also, how long should be the maintenance in Q1 in order to check that with the mill linings replacement? Just a third one on Tucumã, can you please reconcile the production guidance for 2036? I mean, what are you guys expecting in terms of grades and throughput ramp up throughout the year? No more questions. Thank you.

Speaker #4: So, can you provide us an update here? Have you guys already ordered the mobile filter that is expected to increase the filter availability? And if they did it on time, it could be very helpful. Also, how long should we plan the maintenance in the first quarter in order to advance with the new replacement? And just to turn the one on to Kumar, can you please reconcile the production guidance for 2026?

Speaker #4: I mean, what are you guys expecting in terms of grades and throughput ramp-up throughout the year? Those are the questions. Thank you.

Speaker #1: Thank you . Quite a bit to unpack there . So if I miss something I apologize . Just just ask it again . But thanks for the questions So so first on the on the the filter press capacity .

Makko DeFilippo: Thank you. Quite a bit to unpack there, so if I miss something, I apologize. Just ask it again. Thanks for the questions. So first on the filter press capacity. Yes, that equipment has been ordered. It's being manufactured. As I said in the prepared remarks, that is a very important objective of ours. Given what we've outlined, it's not included in our guidance, first and foremost. We expect the payback on that investment to be very fast in this environment, and we expect it to be operational in Q4.

Speaker #1: Yes. That equipment has been ordered. It's being manufactured, as I said in the prepared remarks. That is a very important objective of ours.

Speaker #1: But given the the given what we've outlined , it's not included in , in our guidance . First and foremost , we expect the payback on that investment to be very fast in this environment .

Speaker #1: And we expect it to be operational in Q4, as both the quantum of the investment there, as well as the current prevailing copper price, mean that investment and completion of that project has very little influence on how we think about our business for 2026.

Makko DeFilippo: As of both the quantum of the investment there, as well as the current prevailing copper price, that investment and completion of that project has very little influence on how we think about our business for 2026. As I said, it was not included in our guidance. That's first and foremost on that point. The second part of your question was related to the maintenance that happened related to the mill lining. To be clear there, we expected that maintenance to occur in Q1. We had to pull that into Q4. It's already been completed effectively for the year. That was approximately a 10-day period of downtime that happened in Q4 and impacted our-

Speaker #1: As I said , it was not included in our guidance . So that's first and foremost on that point . The second part of your question was related to the maintenance that happened , related to the mill lining .

Speaker #1: So to be clear there , we expected that maintenance to occur in Q1 . We had to pull that into Q4 . So it's already been completed effectively for for the year .

Speaker #1: That was that was approximately a ten day period of downtime that happened in in Q4 and impacted our our Q4 results .

Emerson Vieira: All right.

Makko DeFilippo: Our Q4 results.

Speaker #4: All right. So no, no more downtime. That's really sad.

Emerson Vieira: No, no more maintenance downtime for Q. That's really sad.

Makko DeFilippo: Well, we have planned downtime every month, so that is still part of our team, but we have no extended period of downtime that we're planning in Q1 of this year.

Speaker #1: We have planned downtime every month, so that is still part of our team, but we have no extended period of downtime that we're planning in Q1 of this year.

Speaker #4: All right . Thank you . And the last one on on the reconciliation ingredient throughput comparing to to the guidance , please .

Emerson Vieira: All right. Thank you. Then the last one, on the reconciliation on grade and throughput, comparing to the guidance, please.

Speaker #1: Yeah , great . Great question . Thank you . So you know we obviously came out had a strong strong result last year in terms of grade .

Makko DeFilippo: Yeah. Great, great question. Thank you. You know, when we obviously came out, had a strong result last year in terms of grade, we do expect grades to come down. We are currently looking at, you know, throughout our guidance, just below 3 million tons of processed throughput, and I would say somewhere between 1.3% and 1.4% copper for the full year.

Speaker #1: We do expect grades to come down . We are currently looking at you know , throughout our guidance , just below 3 million tons of of processed throughput .

Speaker #1: And I would say somewhere between 1.3% and 1.4% copper for the full year.

Speaker #4: All right . Thank you

Emerson Vieira: All right. Thank you.

Speaker #3: The next question comes from Gary Zito with Bank of America. Go ahead.

Operator: The next question comes from Guilherme Rosito with Bank of America. Please go ahead.

Speaker #5: Hi . Hello , everyone . Thank you for taking my questions . So I have two . The first is to I wanted to dive a bit deeper into the C1 cash cost guidance .

Guilherme Rosito: Hi. Hello, everyone. Thank you for taking my questions. I have 2. The first is on Tucumã. I just wanted to dive a bit deeper into the C1 cash cost guidance. I just wanted to understand how we could explain the cost increasing throughout the year versus what we're earning for Q4. I appreciate that there's lower grade and you're also not including the future, so with the future, there could be a change to guidance. I'm just trying to understand, as you have more fixed cost evolution as increased processing and also TC/RCs are higher than what you guys are currently doing at Caraíba. I'm just trying to understand all these moving parts and what's driving costs higher this year.

Speaker #5: I just wanted to understand how how we could explain the cost increasing throughout the year versus what we're running for . Sure . I appreciate that there is lower grade , and you're you're not .

Speaker #5: So not including the filter . So with the filter , there could be a change to guidance . But I'm just trying to understand , as you have more fixed cost solution has increased processing .

Speaker #5: And also, TCRC's are higher than what you guys are currently doing. So I'm just trying to understand how these moving parts and what's driving costs higher this year.

Speaker #5: And second , just wanted to explore a bit . If you could talk about the benefits from the mechanization investments , you guys , you guys did last year , how should we expect that to translate into the results this year ?

Guilherme Rosito: Second, on Xavantina, just wanted to explore a bit, if you could talk about the benefits from the mechanization investments you guys did last year. How should we expect that to translate into the results this year? What do you guys expect in terms of grades throughout the year? How they should fluctuate? What sort of volatility we should see throughout the year? That's it. Thank you.

Speaker #5: And what are you guys expecting in terms of grades throughout the year? How should they fluctuate? What sort of trend should we see throughout the year?

Speaker #5: So that's it. Thank you.

Speaker #1: Thank you for the questions . So yeah , starting with Tacoma Really really good question . There . Main drivers for for guidance .

Makko DeFilippo: Thank you for the questions. Yeah, starting with Tucumã, a really, really good question there. Main drivers for guidance, as you mentioned, is grade. Obviously we're coming off of a year of significantly higher grades. That has a direct influence on our Q1 or our C1 costs. We also are putting in additional maintenance efforts there to stabilize the operations. I would refer to those additional costs as non-structural. On the TCRC and shipment side, you know, we've been getting some questions about differences from Caraíba to Tucumã. I would point to two major influencing factors there. Number one, the grade of the concentrate is lower, therefore there's more costs associated on a per pound copper basis, number one. Number two, we have quite a bit further to transport that material.

Speaker #1: As you mentioned, it is grade. So obviously we're coming off of a year of significantly higher grades, and that has a direct influence on our Q1, or C1, costs.

Speaker #1: We also are putting in additional maintenance efforts . There to stabilize the operations . Those are I would refer to those additional costs as non-structural on the tcrc and shipment side .

Speaker #1: We've been getting some questions about differences from Kariba to Tukuma . I would point to 222 major influencing factors . Their number one , the grade of the concentrate is lower .

Speaker #1: So therefore there's more costs associated on a per pound copper basis . Number one . Number two , we have quite a bit further to transport that material .

Speaker #1: And so when you take those two together you we do see higher TCR sees . We're seeing a market now in the tcrc across our business that that looks favorable relative to where we expected it to be for the budget .

Makko DeFilippo: When you take those two together, we do see higher TC/RCs. We're seeing a market now in the TC/RC across our business that looks favorable relative to where we expected it to be for the budget. That said, those are mostly longer-term contracts that we have in place, so we are not getting the full benefit of the benchmark pricing. More fundamentally, as you'll probably appreciate better than most people, we are seeing a very strong BRL headwind across our business. That's true across all of our operations, and that's been reflected in our guidance. I would say big moving factors there on Tucumã cost drivers would be the grade that we're mining, the additional maintenance costs that we're incurring.

Speaker #1: That said, those are mostly longer-term contracts that we have in place. So we are not benefiting from the benchmark pricing.

Speaker #1: And then more fundamentally , is , as you'll probably appreciate , better than most people , we are seeing a very strong BRL headwind across our business .

Speaker #1: That's true across all of our operations, and that's been reflected in our guidance. So I would say big, big moving factors there on Tucuma cost drivers would be the grade that we're mining.

Speaker #1: The additional maintenance costs that we're incurring . Again , we expect we do expect to see a benefit in Q4 from those costs .

Makko DeFilippo: Again, we do expect to see a benefit in Q4 from those costs. The TCRCs and shipments, related costs in part because the grade of concentrate is lower than Caraíba. Your second question on the benefits of mechanization really points to two things. You know, as you've heard me talk about on a number of calls here over the year, reducing exposure of our workforce is one of the top benefits of that investment, and it was one of the key driving factors in making that investment. Getting our workforce away from the work phase to the maximum extent possible. That's number one. Number two, if you just take a step back, and I hope to have the opportunity to show you what the team's been doing at Xavantina later this year.

Speaker #1: The TCR and shipments related costs, in part, are because the grade of concentrate is lower than Kariba. Your second question on the benefits of mechanization really points to two things.

Speaker #1: You know, as you've heard me talk about on a number of calls here over the year, reducing exposure of our workforce is one of the top benefits of that investment.

Speaker #1: And it was one of the key driving factors in making that investment. So, getting our workforce away from the work face to the maximum extent possible.

Speaker #1: So that's number one. Number two, if you just take a step back and hope you have the opportunity to show you what the team's been doing at Japan-China later this year.

Speaker #1: But you know , that mill only operates between 15 and 20 days . Per month . And that's a function of the asset being mined constraint .

Makko DeFilippo: You know, that mill only operates between, you know, 15 and 20 days per month, and that's a function of the asset being mine constraint. As we look ahead to the future, and notwithstanding the cadence of production that we just talked about this year, given the tie-in of the ventilation circuit improvements that we're making, we expect over time here to be able to better match mine output with mill capacity. Again, not reflected in our long-term guidance, but it's one of the key low-hanging value drivers that we see in our business. You know, Gelson and the team here are working diligently, and we hope to be in a position to talk about what that might look like later in the year.

Speaker #1: So as we look ahead to the future and notwithstanding the cadence of of of production that we just talked about , this year , given the tie in of the ventilation circuit improvements that we're making , we expect over time here to be able to better match mine output with mill capacity .

Speaker #1: Again , not reflected in our long term guidance , but it's one of the key low hanging value drivers that we see in our business .

Speaker #1: And you know, Gelson and the team here are working diligently. And we hope to be in a position to talk about what that might look like later in the year.

Speaker #5: Super clear, Michael. Thank you.

Guilherme Rosito: Super clear, Michael. Thank you.

Speaker #3: The next question comes from Fahad Tariq with Jefferies. Please go ahead.

Operator: The next question comes from Fahad Tariq with Jefferies. Please go ahead.

Speaker #6: Hi . Thanks for taking my questions . There was a comment made earlier on the call about potential capital return once , once the net debt to EBITDA gets to the targeted levels below one times and maybe just any additional color on that , what form that would be in timing , etc.

Fahad Tariq: Hi. Thanks for taking my questions. There was a comment made earlier on the call about potential capital return once the net debt to EBITDA gets to the targeted levels below 1x. Maybe just any additional color on that, what form that would be and timing, et cetera.

Speaker #1: Yeah , I'll jump in . The Wayne can Wayne can can piggyback if you if I missed anything or has anything to add I would say really there's there's three steps here that we see as being critical critically important to driving that decision .

Makko DeFilippo: Yeah. I'll jump in then Wayne. Wayne can take you back if I missed anything or has anything to add. I would say really there's three steps here that we see as being critically important to driving that decision and timing. First and foremost, as we mentioned, we wanna see our net debt leverage ratio below 1x. As you can see from our Q4 results, we're given where we were in Q3 to Q4, we're rapidly approaching that metric. Obviously, the world is a volatile place, so we'll see what happens over the next few quarters, but we're pretty close to that metric at 1.2x right now. Secondly, as we mentioned, we wanna pay down our revolver. As at year-end, we had $155 million drawn.

Speaker #1: And timing . First and foremost , as Wayne mentioned , we want to see our net debt leverage ratio below one times . As you can see from our Q4 results , we're given where we were in Q3 to Q4 , we're rapidly approaching that metric .

Speaker #1: Obviously, the world is a volatile place, so we'll see what happens over the next few, but we're pretty close to that metric.

Speaker #1: At 1.2 times right now . Secondly , as we mentioned , we want to we want to pay down our revolver . So as at year end we had $155 million drawn .

Speaker #1: That's just a logical place to , to to to pay down our debt . And again , we we are cognizant that paying down debt , including our revolver , is a de facto return to shareholders .

Makko DeFilippo: That's just a logical place to pay down our debt. Again, we are cognizant that paying down debt, including our revolver is a de facto return to shareholders. That's an important component of that strategy. Number three, we're having a lot of discussions with our top shareholders about what that might look like and timing. I would say stay tuned. Let's get through steps one and two before we get too excited about step three.

Speaker #1: So that’s an important component of that strategy. And number three, we’re having a lot of discussions with our top shareholders about what that might look like.

Speaker #1: And timing—I would say stay tuned. Let's get through steps one and two before we get too excited about step three.

Speaker #6: Sounds good . And then maybe on fairness , you know , the idea of you're entering a period where some of your peers are getting into a build cycle , and I guess much longer dated .

Fahad Tariq: Sounds good. Maybe on Furnas, you know, the idea of you're entering a period where some of your peers are getting into a build cycle and Furnas is, I guess, much longer dated. Any opportunity to or any appetite to try to accelerate that? Is that even possible given, like, the stage it's at right now in terms of the earning agreement and what needs to be done?

Speaker #6: Any opportunity to, or any appetite to, try to accelerate that? Or is that even possible given what the stage is at right now, and the terms of the earning agreement and what needs to be done?

Speaker #1: Yeah , we're we're very excited about fairness , as you probably heard in our prepared remarks and saw in , in our in our webcast materials , the reality is , you know , it's it's a it's a few years out .

Makko DeFilippo: Yeah. We're very excited about Furnas, as you probably heard in our prepared remarks and saw in our webcast materials. The reality is, you know, it's a few years out. We like that positioning. We need to do work to advance through a pre-pre-feasibility study, execute on some of those value drivers that we see as low-hanging fruit to increase the value of the project, increase by-product revenue. We still need to do advance several permitting work streams. The reality, I think, is we do have the appetite to advance that project as fast as possible. I would say that we're already doing that, and we still expect modest capital spend over the next few years as a result of the acceleration there.

Speaker #1: We like that positioning . We need to do work to advance through pre-feasibility study , execute on some of those value drivers that we see as low hanging fruit to increase the value of the project , increase byproduct revenue .

Speaker #1: And then we still need to do advanced several permitting work streams. The reality, I think, is we do have the appetite to advance that project as fast as possible.

Speaker #1: I would say that we're already doing that , and we still expect modest capital spend over the next the next few years . As a result of the of the acceleration , there

Speaker #6: Okay, great. Thank you.

Fahad Tariq: Okay, great. Thank you.

Speaker #3: The next question comes from Stefan Ioannou with ATB Cormark. Please go ahead.

Operator: The next question comes from Stefan Ioannou with ATB Cormark. Please go ahead.

Speaker #7: Yeah . Thanks very much , guys . I'm just kind of curious . Back on the gold . Concentrate sales . I think originally it was suggested that you might we're anticipating selling down the entire stockpile over , say , 12 to 18 months .

Stefan Ioannou: Yeah, thanks very much, guys. Just kind of curious back on the gold concentrate sales. I think originally it was suggested that you were anticipating selling down the entire stockpile over, say, 12 to 18 months. Given our better understanding of the rainy season and whatnot now, is that an sort of a number we should think it was probably gonna be stretched out over a bit more time?

Speaker #7: Just given our better understanding of the rainy season and whatnot . Now , is that a sort of a number we should think is probably going to be stretched out over a bit more time ?

Speaker #1: Yeah . Look , let's see . Right . That 12 to 18 months . Right . We talked about that timeline in November .

Makko DeFilippo: Yeah. Look, let's see, right? that 12 to 18 months, right, we talked about that timeline in November. If you look at what we talked about in our guidance camp out this year, we said through mid-2027, those timelines are-

Speaker #1: If you put out if you look at what we talked about in in our guidance came out this year , we said through mid 2027 those , those timelines are kind of give or take , give or take a month are pretty well aligned from our perspective .

Stefan Ioannou: Yeah.

Makko DeFilippo: You know, kind of give or take a month are pretty well aligned from our perspective.

Speaker #7: Okay , okay . So still mid 2027 ish okay . And and just maybe switching gears just on the you mentioned an exploration spend of 30 to 40 million .

Stefan Ioannou: Okay, so still mid-2027-ish. Okay. Maybe switching gears, just on the, you mentioned an exploration spend of $30 to 40 million. Is that really the lion's share at Furnas, or is there any other sort of notable projects we should be thinking about from an exploration point of view this year?

Speaker #7: Is that is that really the lion's share at Furnas or is there any other sort of notable projects we should be thinking about from an exploration point of view this year ?

Speaker #1: It is great question . Yes , the lion's share of that is at Furnas . I would say that , you know , we're still advancing some opportunities throughout the portfolio , both at Tukuma and at Tukuma , Japan , China and Kariba , at various stages of development .

Makko DeFilippo: It is. Great question. Yes, the lion's share of that is at Furnas. I would say that, you know, we're still advancing some opportunities throughout the portfolio, both at Tucumã, Xavantina, and Caraíba, at various stages of development. Again, I think the best guidance I can give you at this point is that we're excited about what we're doing there. We expect to give an update at our investor day later in the year.

Speaker #1: Again, I think the best guide to give you at this point is that we're excited about what we're doing there.

Speaker #1: We expect to give an update at our Investor Day later in the year.

Speaker #7: Okay, okay, great. Thanks very much, Michael.

Stefan Ioannou: Okay. Okay, great. Thanks very much, Michael.

Speaker #3: The question comes from Craig Hutchinson with TD Cohen. Please go ahead.

Operator: The next question comes from Craig Hutchison with TD Cowen. Please go ahead.

Speaker #1: Hi .

Speaker #8: Good morning, guys. I was just wondering if the heavy rainfalls will have any impacts on concentrate shipments, or the timing of shipments, from Takuma as well?

Craig Hutchison: Hi, good morning, guys. I was just wondering if the heavy rainfalls, will that have any impacts on concentrate shipments or timing of shipments from Tucumã as well, or is it just isolated to Xavantina?

Craig Hutchinson: Hi, good morning, guys. I was just wondering if the heavy rainfalls, will that have any impacts on concentrate shipments or timing of shipments from Tucumã as well, or is it just isolated to Xavantina?

Speaker #8: Or is it just isolated to Japan-China?

Speaker #1: Yeah , great question . We we plan for cadence across our operations for a for a normal amount of operational disruption . I would say that what we've seen to date , either at our other operations is in line with what we expected .

Makko DeFilippo: Yeah, great question. We plan for cadence across our operations for a normal amount of operational disruption. I would say that what we've seen to date at our other operations is in line with what we expected and built into our budget and guidance for the year. We're not seeing anything out of the ordinary in terms of operational disruption. There is operational disruption across all our operations due to the rain season. That's been reflected in our guidance and how we think about cadence for the full year.

Speaker #1: And built into our budget and guidance for the year. So we're not seeing anything out of the ordinary in terms of operational disruption.

Speaker #1: There is operational disruption across all our operations due to the rainy season that's been reflected in our guidance and how we think about cadence for the full year.

Speaker #8: Okay, great. And then, just in terms of your C1 cash costs, are you able to provide what you're assuming for TCRs for the year?

Craig Hutchison: Okay, great. Then just TCRCs in terms of your C1 cash costs. Are you able to provide what you're assuming for TCRCs for the year?

Craig Hutchinson: Okay, great. Then just TCRCs in terms of your C1 cash costs. Are you able to provide what you're assuming for TCRCs for the year?

Makko DeFilippo: Those are based on long-term contracts that are commercially sensitive. I would say.

Speaker #1: Those are based on long term contracts that are commercially sensitive . But I would say , okay , the what we've heard in the market is well below zero .

Makko DeFilippo: Those are based on long-term contracts that are commercially sensitive. I would say.

Craig Hutchison: Okay.

Craig Hutchinson: Okay.

Makko DeFilippo: What we've heard in the market is well below zero. We're not reflecting that at either of our operations. As I said, they're long-term contracts that are commercially sensitive. Still very low in a historical context. As I mentioned, when I think about what are the big headwinds and tailwinds for our business, you know, at Caraíba, we have a big tailwind from by-product gold prices. That was probably pretty clear in if you look at how that by-product line item has tracked over the last several years. We're seeing headwinds on seaborne shipping freight given what's happening in the world today. Also on the BRL, which has been a big.

Speaker #1: We're not reflecting that at either of our operations . And as I said , they're long term contracts that are commercially sensitive , still very low in a historical context .

Speaker #1: As I mentioned , when I think about what are the what are the big headwinds and tailwinds for our business ? You know , at we have a big tailwind from from byproduct gold prices .

Speaker #1: That was probably pretty clear. And if you look at how that byproduct line item has tracked over the last several years, we are seeing headwinds on seaborne shipping freight, given what's happening in the world today.

Speaker #1: And then also on the BRL , which has been a big I think last year , the BRL was in the top , was one of the top performing currencies against the US dollar .

Makko DeFilippo: I think last year the BRL was one of the top performing currencies against the US dollar. That's a bit of a headwind. Definitely some gives and takes. We feel pretty happy with where our guidance is at this point in time, given some of the gives and takes that we're seeing there. Obviously, we'll, you know, keep everyone updated if we see things moving significantly one way or another. Very great. Thanks, guys.

Speaker #1: And so, that's a bit of a headwind. So definitely some gives and takes. We feel pretty happy with where our guidance is at this point in time.

Speaker #1: Given some of the the gives and takes that we're seeing there . But obviously we'll , you know , keep everyone updated if we if we see things moving significantly one way or another .

Craig Hutchinson: Very great. Thanks, guys.

Speaker #8: Okay. Great. Thanks, guys.

Speaker #3: Once again, if you have a question, please press star, then one. The next question comes from Anita Soni with CIBC World Markets.

Operator: Once again, if you have a question, please press star then one. The next question comes from Anita Soni with CIBC World Markets. Please go ahead.

Speaker #3: Please go ahead. Hi. Good morning, guys.

Anita Soni: Hi. Good morning, guys. Thanks for taking my questions. I just wanted to follow up a little bit on Furnas. I was wondering in terms of... I wanted to tie in the exploration drilling that you've done with the PEA. Can you just talk about how much of the drilling that you've done, how much was included in this PEA? Is there still, like, some that was outlined that didn't get included?

Speaker #9: Thanks for taking my questions. I just wanted to follow up a little bit on Fernandes. I was wondering, in terms of—I wanted to tie in the exploration drilling that you've done with the PA.

Speaker #9: Did you just talk about how much of the drilling that you've done, how much was included in this PA, and is there still some that was outlined that didn't get included?

Speaker #1: Yeah , perfect . Thank you for asking . The question . You're absolutely right . The PE we started drilling at tail end of of 2020 for the PE includes 28,000m of drilling .

Makko DeFilippo: Yeah, perfect. Thank you for asking the question. You're absolutely right. The PEA, we started drilling at the tail end of 2024. The PEA includes 28,000 meters of drilling of the 50,000 meters that we drilled last year, we expect to complete another 50,000 meters this year. If you're looking for, you know, there's several stages under the earn-in agreement. We expect to complete all phases of drilling, all drilling requirements by the end of 2026. As I mentioned, that PEA only includes 28,000 meters of drilling. Our objectives with the drill program that we completed in the second half of last year and the first part of this year are twofold.

Speaker #1: Of the 50,000m that we drilled last year . And we expect to complete another 50,000m this year . So if you're looking for , you know , there's several stages under the agreement , we'll have effectively we expect to complete all phases of drilling , all drilling requirements by the end of 2026 .

Speaker #1: And as I mentioned , that PA only includes 28,000m of drilling . Our objectives with the drill program that we completed in the second half of last year , and the first part of this year Number one , as we move to pre-feasibility study , we we need to convert that inferred mineralization that's included in the PA into measured and indicated resources that we can include it in the mine plan .

Makko DeFilippo: Number one, as we move to pre-feasibility study, we need to convert that inferred mineralization that's included in the PEA into measured and indicated resources, so we can include it in the mine plan. Number two, as you can see in the production profile, you know, really years 16 through 24, we see a drop-off, and that's related to the really to the extent of drilling we've been able to do. We've targeted as part of our drill program some key step outs around some of the planned underground infrastructure that is successful. We expect to improve the production profile later in the mine life.

Speaker #1: And then number two , we as you can see in the production profile , you know , really you're 16 through 24 . We see a drop off and that's related to the really to the extent of drilling .

Speaker #1: We've been able to do . So we've we've targeted as part of our drill program some key step outs around some of the planned underground infrastructure that , that , that if successful , we expect to improve the production profile later in the mine life .

Speaker #1: Obviously, we still need drilling and the mine planning to support what I just said there. But we're looking forward to advancing that workstream and getting it included into the pre-feasibility study.

Makko DeFilippo: Obviously, we still need to do the drilling and the mine planning to support what I just said there. We're looking forward to advancing that work stream and getting it included into the pre-feasibility study.

Speaker #9: Yeah, that was the second question. Just wanting to drill a little bit into the inferred category. What kind of drill density do you have now, and what do you need to get it into for the NE?

Anita Soni: Yeah, that was the second question. Just I'm wanting to drill a little bit into the inferred category. What kind of drill density do you have now, and what do you need to get it into for the M&I?

Speaker #1: Well , I don't have that right off the top of my head . We can circle back on that one . I what I can tell you is that about 60% of the material that we have , including the Pah , is inferred .

Makko DeFilippo: I don't have that right off the top of my head. We can circle back on that one. I, what I can tell you is that about 60% of the material that we have included in the PEA is inferred. You know, I will follow up with you just after this call on drill spacing. Obviously, that'll be outlined in the technical report that'll be filed here shortly. I just don't have that information right at my fingertips.

Speaker #1: You know , I will follow up with you just after this call on on drill spacing . Obviously , that'll be outlined in the technical report .

Speaker #1: That'll be filed here shortly. I just don't have that information right at my fingertips.

Speaker #9: Oh, that's fine. If you're going to file the technical report, that was my third question. When are you going to file that? Because I'd like to get into the weeds on that.

Anita Soni: Oh, that's fine. If you're gonna file the technical report, that's, that was my third question when you're gonna file that 'cause I like to get into the weeds on that. I would also then want to figure out some of the dilution questions as well, 'cause I noticed your M&I in inferred does not have any dilution at all in the answer. That's it for my questions. Thank you.

Speaker #9: And then I would also then want to figure out some of the dilution questions as well, because I noticed your map and inferred does not have any dilution at all in the cancer.

Speaker #9: But that's it for my questions.

Speaker #10: Thank you .

Speaker #1: Yeah , just to clarify , it's an important point on dilution . You're correct . The resource statement doesn't include dilution . The mine plan has been fully diluted and you'll see that reflected around the assumptions that they're outlined in in the technical report okay .

Makko DeFilippo: Yeah, yeah. Just to clarify there, it's an important point on dilution. You're correct. The resource statement doesn't include dilution. The mine plan's been fully diluted, and you'll see that reflected around the assumptions that are outlined in the technical report.

Anita Soni: Okay. All right. Thanks. Thanks a lot.

Speaker #9: All right. Thanks. Thanks for that.

Speaker #3: The next question comes from Dalton Barreto with Canaccord Genuity. Please go ahead.

Operator: The next question comes from Dalton Baretto with Canaccord Genuity. Please go ahead.

Speaker #11: Yeah, thanks for squeezing me in, guys. Morning, team. I just want to follow up on some of that drilling there, but from a different perspective.

Dalton Baretto: Yeah, thanks for squeezing me in, guys. Morning, Marco and team. Just wanna follow up on some of that Furnas drilling there, but from a different perspective. Marco, you talked about all the drilling that was done last year that was not included, a lot of the drilling this year. My understanding was that sort of the high grade cores of the deposit, they extend down deeper and possibly deeper than Vale had anticipated. I'm just trying to understand how much of your drilling is chasing that higher grade material and whether we could see some sort of a grade bump on the next resource update. Thanks.

Speaker #11: Marco, you talked about all the drilling that was done last year that was not included. A lot of drilling this year.

Speaker #11: My understanding was that sort of the the high grade cores of the deposit , they extend down deeper and possibly deeper than that anticipated .

Speaker #11: And I'm just trying to understand how much of your drilling is chasing that higher-grade material, whether we could see some sort of a grade bump on the next resource update.

Speaker #11: Thanks .

Speaker #1: Good questions . Look , I think the way that I would think about this is the , the , the project as it stands today is it stands on its own two feet .

Makko DeFilippo: Good questions. Look, I think the way that I would think about this is, the project as it stands today, it stands on its own two feet, right? We're working on some additional value drivers to smooth out the production profile to further enhance the economics. As you see from the numbers, it absolutely stands on its own two feet. If you look at the last drill hole that we drilled as part of the PEA, I'm gonna quote some numbers here, so take this with a little bit of grain of salt, but it was about around 150 meters at 0.8% copper and a half gram gold more or less.

Speaker #1: Right. We're working on additional value drivers to smooth out the production profile to further enhance the economics. But as you see from the numbers, it absolutely stands on its own two feet.

Speaker #1: If you look at the last drill hole that we drilled as part of the PE, I'm going to quote some numbers here.

Speaker #1: So take this with a little bit of a grain of salt, but it was about around 150 meters at 0.8% copper and half a gram gold, more or less.

Makko DeFilippo: That was the last hole that we drilled that was included in the PEA of that 28,000m program. That intercept was 600m below surface. We clearly see opportunity to extend the deposit both to depth and laterally along strike. We expect to include those in future studies. As I said, we'll be advancing those drill programs here. In terms of grade, a grade bump, look, we still need to do the infill drilling that will be included in the pre-feasibility study. There's several stages of technical studies to go here.

Speaker #1: And that was the last hole that we drilled . That was included in the PE . Of that 28,000 meter program , that that intercept was 600m below surface .

Speaker #1: We clearly see opportunity to extend the deposit, both to depth and laterally along strike. We expect to include those in future studies.

Speaker #1: And as I said , we'll be advancing those drill programs here in terms of grade , grade bump . Look , we still need to do the infill drilling that will be included in in the pre-feasibility study .

Speaker #1: So there's several stages of technical studies to go here . I would say the work that not only we did , but also the very , very strong technical work that Val has done over the years to to build an incredible foundation that we were able to build on .

Makko DeFilippo: I would say the work that, you know, not only we did, but also the very, very strong technical work that Vale has done over the years, to build an incredible foundation that we're able to build on, I think really speaks to the quality of the project. And, you know, we work with our technical team regularly. We have an excellent relationship and we're really moving this forward together to create the best value possible. When I think about what we've done collectively to drive, you know, not only production, substantial lever underground, but also, you know, the mine calls for about 30% of its tailings, expected tailings production to go back underground as paste backfill.

Speaker #1: I think it really speaks to the quality of the project. And, you know, we work with our technical team regularly. We have an excellent relationship.

Speaker #1: And and we're really moving this forward together to create the best , best value possible . And when I think about what we've done collectively to drive not only production substantial underground , but also , you know , the mine calls for about 30% of its tailings , expected tailings production to go back underground as paste , backfill .

Speaker #1: We've really worked jointly to reduce the environmental footprint and hopefully set ourselves up for an excellent fast-track project.

Makko DeFilippo: We've really worked jointly to reduce the environmental footprint, and hopefully set ourselves up for a excellent fast-track project.

Speaker #11: Thanks, Marco. And then can you remind me, is there some sort of a mechanism in your agreement with Vale that gives you the option to buy by the piece that you currently won't earn into?

Dalton Baretto: Thanks, Marco. Can you remind me, is there some sort of a mechanism in your agreement with Vale that gives you the option to buy the piece that you currently won't earn into?

Speaker #1: No, we're very happy to be pursuing this project in partnership with Valley-based Metals.

Makko DeFilippo: No, we're very happy to be pursuing this project in partnership with Vale Base Metals.

Speaker #11: Great . Thanks

Dalton Baretto: Great. Thanks.

Speaker #3: This concludes the question-and-answer session. I would like to turn the conference back over to Makko DeFilippo for any closing remarks.

Operator: This concludes the question and answer session. I would like to turn the conference back over to Marco De Filippo for any closing remarks. Please go ahead.

Speaker #3: Please go ahead .

Speaker #1: Yes . Thank you , everyone for joining us today . Obviously , we're always available for follow up questions . Appreciate the the robust discussion on the Q and A side .

Makko DeFilippo: Yes. Thank you everyone for joining us today. Obviously we're always available for follow-up questions. Appreciate the robust discussion on the Q&A side as usual. I think one last bit of housekeeping here, shortly on our website, for those of you who are interested, we will be hosting a Capital Markets Day in mid-September. That will be physically in person in São Paulo and obviously virtually. As I said, that information will be on our website shortly. Thank you all very much. Have a great weekend. Thank you. Bye-bye.

Speaker #1: As usual, I think one last bit of housekeeping here shortly on our website. For those of you who are interested, we will be hosting a Capital Markets Day.
