I would now like to turn the conference over to Allison Pettit, Vice President, Investor Relations. Please go ahead.

Allison Pettit (VP, Investor Relations)

Thank you, operator, and good morning, everyone. Before we get started, I ask that you view our MD&A for cautionary language regarding forward-looking statements and the risk factors pertaining to these statements. Our MD&A and financial statements are available on our website at edrsilver.com. On today's call, we have Dan Dickson, Endeavour Silver's CEO, Elizabeth Soralis, our CFO, and Don Gray, Endeavour's COO. Following Dan's formal remarks, we will open the call for questions. Now over to Dan.

Dan Dickson (CEO)

Thank you, Allison, and welcome everyone. Before reviewing our 2025 results, I'd like to provide a brief update on Terronera. Operations were temporarily impacted by recent security events in Mexico and Jalisco's Code Red mandate, which required civilians to shelter in place. To comply with the mandate, the uncertainty surrounding the event, and to ensure the safety of our people, we paused Terronera's operations Sunday evening. Operations resumed Wednesday, February 25th, once supply routes were confirmed to be secure. We will continue to monitor the developments closely, and the safety of our employees and contractors remain our top priority. With that, I'd like to briefly touch on the current silver and gold market. Over the past year, we've seen exceptional gains in renewed investor interest in precious metals, driven by inflationary pressures, global economic uncertainty, and ongoing political tensions.

Silver and gold continue to be viewed as safe haven assets, with silver also benefiting from rising industrial demand, especially in the green energy and technology spaces. This momentum has continued into 2026 as gold trades well above $5,000 and silver is elevated above $90, reflecting ongoing confidence and reinforcing the importance of our strategic initiatives and our commitment to delivering value for our shareholders. We are extremely well-positioned to benefit from the current silver prices and believe there is substantial runway remaining in this cycle. Moving over to the specifics of the company, 2025 was a transformational year for Endeavour Silver. We took a major step forward with the acquisition of Kolpa in May, Terronera achieving commercial production in October, and agreed to the sale of the Bolanitos Mine, which closed in January.

In December, we raised $350 million through a convertible debt offering, strengthening our balance sheet and positioning ourselves to advance the Pitarrilla development asset. These milestones lay a solid foundation for performance and sustained growth as we look ahead to the future and position ourselves as a stronger company within the industry. In 2025, Endeavour Silver produced 11 million ounces of silver equivalent metal, including base metal production from Kolpa, making a 48% increase compared to 2024. In Q4, Endeavour Silver produced 2 million ounces of silver and 14,000 ounces of gold, totaling just shy of 4 million silver equivalent ounces. This represents a 146% increase compared to Q4 of 2025 due to the addition of Kolpa, Terronera, and the higher grades at Bolanitos.

Excluding Coba and Terronera, this was a 27% increase compared to the same period last year. In 2025, the company reported record revenue of $468 million, up 115% compared to 2024, with cost of sales of $385 million, mine operating earnings of $83 million, and mine operating cash flow before taxes of $156 million. Mine operating cash flow before working capital changes rose by 116%, while cash costs increased to $19 per ounce of payable silver, primarily driven by the substantial changes in our production profile. In Q4, Endeavour recognized adjusted net earnings of $4.8 million or an adjusted earnings of $0.02 per share.

Due to realized losses from derivative contracts and higher financing costs in relation to the early repayment of the debt facility. Direct operating costs per ton increased by 8% this year, primarily driven by elevated costs at Terronera during its initial quarter of production. Looking ahead, we anticipate a substantial reduction in these costs as we transition from diesel to liquefied natural gas in Q2 of 2026, complete the demobilization of our construction team, benefit from workforce and logistics optimization plans implemented in January, and maintain a throughput at 2,000 tons per day through 2026. Kolpa will also see an improved cost efficiency as its plant expands 2,500 per day tons per day here in Q1. For clarity, our direct operating costs per ton include direct input costs associated with mining, milling, and site level G&A.

Our definition of direct costs per ton includes royalties, mining duties, and the purchase of third-party material. Changes in the metal price have a meaningful impact on our direct cost per ton. For example, for every dollar increase in silver, our cost per ton rise by about $0.90 at Terronera, $0.50 at Kolpa, and $3.80 per ton at Guanaceví, mainly due to the higher royalties, duties, and third-party ore purchases, elevated corporate G&A, and the addition of Terronera. All-in sustaining costs net of byproduct credits were elevated this quarter with higher royalties, duties, third-party ore purchases, elevated corporate G&A, and the addition of Terronera. Terronera incurred higher costs due to higher sustaining capital expenses during the first quarter of operations. Terronera's All-in sustaining cost includes capital expenditures of $16.3 million for the quarter, which worked out to approximately $48 All-in sustaining cost per ounce.

This includes one-time investments related to new mining operations. These costs are expected to decrease as we move through 2026. The elevated corporate G&A was impacted by the divestiture of Bolanitos, the appreciation of deferred share units, and the integration of all our new operations. As of December 31st, 2025, the company's cash position stood at $215 million, providing us with the financial strength and flexibility to advance our strategic initiatives. This robust foundation allows us to remain nimble and responsive to new opportunities while staying focused on driving progress at Pitarrilla, where we continue to invest in exploration, technical studies, and the economic evaluation. As we move through 2026, our attention remains focused on several operational investment priorities across our main operations and projects, each serving as a catalyst for our continued success and growth in 2026.

At Terronera, our primary focus is disciplined execution as we transition into higher grade zones in the second half of the year. We are seeing gradual improvements towards designed operating parameters, including nameplate throughput, recoveries, and mine output. Grades are aligning with plan. Operations are beginning to establish a consistent rhythm rather than the volatility of a typical ramp-up. As we eliminate ramp-up or start-up costs, we expect direct cost per ton to improve through the year. Secondly, at Kolpa, we are actively advancing our expansion initiative, increasing capacity from 2,000 tons per day to 2,500. We anticipate achieving this milestone in the coming weeks, which will enhance our throughput and support our growth objective. Additionally, we remain focused on delivering a resource estimate later this year.

At Pitarrilla, the company's next major development project and one of the world's largest undeveloped silver deposits, our commitment remains very strong, with a planned $68 million investment in 2026. This includes the completion of an NI 43-101 feasibility study targeted for completion in Q3 2026, along with early work such as commencement of the construction camp, continued ramp advancement through the manto, and procurement of long lead equipment to support the basic and detailed engineering. We are positioning the project to have a well-informed construction decision in early 2027, supporting our strategic strategy of significant organic growth. 2025 marked a defining chapter in our story. As we continue on this exciting path, I want to extend our gratitude to our valued shareholders and stakeholders for your confidence and partnership.

We remain committed to creating lasting value, driving operational excellence, and building a premier senior silver company. Thank you for your continued support and engagement. With that, I'm happy to open this to questions. Operator, please proceed to our Q&A session.

Operator (participant)

Thank you. To join the question queue, you may press Star then 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 then two. The first question comes from Wayne Lam with TD Securities. Please go ahead.

Wayne Lam (Director, Mining Research)

Yeah, thanks. Morning, guys, or morning, afternoon over here. I'm just wondering, just on the updates operational at Terronera, can you discuss the mill availability and what happened with the electrical interruptions? If I recall, you guys also had an electrical issue in late September, which kind of resulted in the delay to commercial production. Just wondering exactly what's going on there. Have you seen an improvement on those issues? Have those been resolved in the first two months of this year?

Dan Dickson (CEO)

Yeah. Thanks for the question, Wayne. I mean, the quick answer is yes, we have seen a lot of improvement in January and February. We've done very well from a throughput standpoint. As you recall, back in September, we had resistors that had to replace early October, and it took six days, seven days for those to come in as they were one-time items. We had a lot of electrical disruptions just because we're on diesel gen sets. We were at max power, and we had to make some adjustments in Q4 to that. We were getting lots of starts and stops. Losing maybe one hour or two hours on various days. Starting and stopping impacts recoveries, obviously impacts throughput. We've seen that kind of stabilize late December obviously through January and February.

The most important part to those temporary diesel gen sets is we have received our permits to operate our LNG plant. We are allowed to vaporize our liquefied natural gas into natural gas and ultimately electricity. We are completing that connection point here in Q1. The provider of the liquefied natural gas has obtained their permit to transport, and they're just waiting on a storage permit on site, that we're gonna look at here or we expect to receive over the next couple weeks. Our expectation is that we'll be on our LNG plant in Q2. It does a significant thing for our stability of electrical continuity, but also from a cost standpoint.

Going from diesel gen sets into the LNG plant takes us from $0.33 per MWh to $0.17, almost $8 a ton at this point. We're excited to get on that for a number of reasons. Obviously, reliability and cost being the main two.

Wayne Lam (Director, Mining Research)

Okay, great. Thanks. Maybe just on the grade profile at Terronera, you guys had previously guided the 122 gm silver and 2.5 gold through the first 6 months of operation. The guidance for this year implies that you'll average 120 gm through the entirety of 2026.

Dan Dickson (CEO)

Yep.

Wayne Lam (Director, Mining Research)

I know you guys had talked about, you know, some of mining of the lower grade stockworks driving that, but just wondering if you might have any guidance on grades in terms of a split in H1 versus the prior 2022, and where we should think about that with the higher grades you're projecting into H2. Then just are the lower grades entirely being driven by that lowering of the cutoff, or is there some attribution as well to greater dilution or lower reconciliation versus the block model?

Dan Dickson (CEO)

I think the first couple questions, block model reconciliation has been relatively strong, better as we've moved forward and we've got deeper into the mine plan. We do have lower silver grades and ultimately gold grades because of some of that stockwork. Right now, that stockwork isn't a significant amount. As you know, in the back half of the year, we get into the main chute of Terronera, and that's the goal. That's where our highest grade points are, and that's where our biggest splits are. As far as the breakdown between H1 and H2, I don't have that rate in front of me, but it is a gradual increase, so Q1-Q2, Q3-Q4. Each quarter gets better, as we bring more and more of that chute in.

For those that are listening, we made the decision about almost one year ago now, maybe nine months ago, that we would go into a lower grade part of the ore body as we start with initial production, obviously, because we didn't wanna end up having ounces of silver and gold into our tailings, dam, ultimately, as we go through kind of your irregular startup issues and building up our recovery. This was by design, Wayne. Again, it's lining up relatively well to plan. We're slightly lower because we are taking that stockwork. It's very difficult to speak to that stockwork and the impact overall. As we go through the year, we'll bring more and more into the plan and more of the high grade stuff and hopefully go back to that stockwork later on.

Wayne Lam (Director, Mining Research)

Okay. maybe just as a follow-up to that, the mine plan in the early years of operation is, you know, in the, in the realm of, you know, 230 to, let's call it 280 grams per ton silver. Like, when would we expect that type of material to be mined and processed through the mill? Is that more of a 2027 thing?

Dan Dickson (CEO)

Exactly. 2027.

Wayne Lam (Director, Mining Research)

Okay. Okay, good. Maybe just last one for me, just on the guided capital spend this year. There's been quite a bit of spend budgeted at Terronera, particularly towards additional mine development, which is driving your higher ASIC. Just wondering if that reflects a catch-up on development that was anticipated to have been completed through the initial construction period, and if that drops off substantially, as we progress through the year. Would you see your development meter still as relatively behind where you'd like to be, through the early stages of the operation?

Dan Dickson (CEO)

Yeah. We're a little bit behind, but not relatively behind. You'll see that in our guidance that we put out in January, we had a $56 million capital budget for Terronera. Similarly, I think we spent almost $17 million in Q4 at Terronera, which we defined as sustaining capital. Obviously, moving from commercial production into or from construction into commercial production, we have had some capital programs slosh into Q4 and ultimately Q1, Q2. As we move forward through Terronera, we expect that to come down. There are one-time activities that are included in this CapEx. For example, as we already talked about the LNG plant and the completion of that. We're waiting on a CONAGUA permit for waste dump two. That's gonna reduce our trucking capacity, and we'd have some development around waste dump 2. We expect that.

We have a backfill plant that we're currently leasing. We're gonna buy that. There's a number of one-time items in our sustaining CapEx that you could argue is related to the actual build of Terronera. Obviously, we're taking that through sustaining CapEx. We don't wanna play with numbers and start calling certain things growth or sustaining. At this point, it is what it is, but do expect that to come down as we move through 2026 and ultimately, 2027. We expect to be at a regular sustaining CapEx rate.

Wayne Lam (Director, Mining Research)

Okay, perfect. Thanks for taking my questions.

Dan Dickson (CEO)

No problem. Thanks a lot, Wayne. Those are very good questions. Thank you.

Operator (participant)

The next question comes from Heiko Ihle with H.C. Wainwright. Please go ahead.

Heiko Ihle (Managing Director, Senior Metals and Mining Analyst)

Hello there, and team, thanks for taking my questions.

Dan Dickson (CEO)

Hey, Heiko. Nice to hear from you.

Heiko Ihle (Managing Director, Senior Metals and Mining Analyst)

Hey, Terronera commercial production obviously was October 1st, you know, we'll be in March 1st here in the very near future, it's five months later. You want to just maybe provide the audience here with a little bit of color on how things went since then, maybe things that went better, things that went worse, any sort of bottlenecks in supply chains or at site, or just things that came a little bit different from your expectations? Again, not necessarily just worse, but also, I mean, I assume some things went substantially better than you thought.

Dan Dickson (CEO)

Do you mean over the course of the construction period, or just over operations of the last five months, Heiko?

Heiko Ihle (Managing Director, Senior Metals and Mining Analyst)

Operations over the last 5 months.

Dan Dickson (CEO)

I mean, to be honest, I mean, it's our first time doing an initial build, our first mine that we brought into commercial production. Obviously, there's things that have gone extremely well, things that we wish could be better. I mean, I think it's normal through a ramp-up phase, that it's two steps forward, one step back. That's what through all of our past experiences and Don's experiences. There's things that we felt like we could improve on maybe from a initial startup and ramp-up, better knowledge almost of going to the initial plan. Everybody has different ideas, it's sticking to the original plan. From that, starting with the variables of trying different reagents at different times, putting various oxygens through it. Because of the terrain around Terronera, the topography at all, it's very mountainous.

We don't have a lot of flexibility with laydown yards. We only have about 80,000 tons, even less than that right now, stockpile that sits near the plant. What comes out of the mine kinda gets fed right into the plant. We're continually learning about the ore body, trying to find what's best from a recovery standpoint. Again, January, February, we've seen very good throughput up until Sunday night. We obviously shut down for a couple days. Again, going forward, we expect that to be very good. And it's the gradual ramp-up of recoveries. We've been running lower silver or silver grades, as Wayne kind of pointed out, and those will improve through the year, and we expect recoveries to improve with that.

I think our team's been phenomenal at finding flexible ideas using plans B and C to get to where we need to get to. Now we wanna get into the rhythm and kind of be steady state and get into normal course operations. We look forward to that.

Heiko Ihle (Managing Director, Senior Metals and Mining Analyst)

Fair enough. Just, like, I guess a little bit more touchy-feely, as silver is at $94 right now, I mean, assuming silver prices stay here or maybe even, you know, go up a little bit more, is there an impact, a quantifiable impact of where you mine across your asset base and what you, internally are envisioning on mining costs, like direct costs, for labor and longevity across your asset base?

Dan Dickson (CEO)

Yeah. I mean, that's a very big question.

Heiko Ihle (Managing Director, Senior Metals and Mining Analyst)

You hinted at some of that earlier. Sorry, go ahead.

Dan Dickson (CEO)

That's a very broad question of with $94, first off, it's a phenomenal environment, and we expect cash flows to be very significant. There's a big impact to us at Guanaceví because we pay a significant royalty at Guanaceví, 16% to Minera Frisco that owns the main concessions of that. Further with there, we toll ore. I think in Q4, we did close to 20% of our throughput was tolled ore. That's gonna continue. Obviously, there's a lot of family-run operations. The government built in 1981, that Guanaceví plant, and we're required to take up to 10%. Quite frankly, it extends the life of our mine. We get good margins on some of that tolled ore. It's just expensive to buy.

Flip side of that, Special Mining Duty, which is an EBITDA tax, and that's included in our cost per ton and our direct cost per ton. With higher prices, and we kind of put this in our guidance news release, it's gonna drive our direct cost per ton in. Again, for our audience, we have a direct operating cost per ton, which is mining, milling, and our indirect costs. Our direct costs include royalties, duties, and purchased ore. Those last three items go up with higher prices. We still have great margins, but it means rising cost per ton. We get a lot of questions of why are costs rising.

For the costs that we can control, we've been through our negotiations with our unions out of Mexico and our general increase is about 6%, which is a bit higher than our budgeted number of 5%. That was all included in guidance. Of course, we're gonna start seeing pressure on our inputs. I think that's just natural at these prices. It's our job as management to work through that. That's all included in our guidance numbers. I think it's imperative at Kolpa and Terronera, we have a lot smaller royalties there, so it's easier to contain those costs. Of course, as we evaluate projects going forward, we're looking at these higher prices and what's the impact long term on costs.

I don't know if that fully answers your question, Heiko, but again, in our guidance news release, we kinda touch on that, in depth a bit.

Heiko Ihle (Managing Director, Senior Metals and Mining Analyst)

Yeah. Yeah. No, you did. You got exactly where I wanted to go with this. Thank you very much. I'll get back in the queue. Have a good weekend.

Dan Dickson (CEO)

Thanks, Heiko. Very good question.

Operator (participant)

The next question comes from Soundarya Iyer with B. Riley. Please go ahead.

Soundarya Iyer (Senior Equity Research Associate)

Hi, team. Congratulations on the quarter. My question is more on this derivative hedge. I mean, there is good amount of detail in the MD&A, but, could you help me understand, you know, the remaining notional exposure and the cash settlement cadence over the next 12 months? What about the risk management strategy in order to manage this strength in precious metals?

Dan Dickson (CEO)

I'm happy to talk about that. I mean, it's an important part right now on our balance sheet that under the project loan facility that we borrowed to build the Terronera mine, we borrowed $135 million from two lenders. When we went into that facility agreement back in 2022, we were required to hedge 68,000 ounces of gold, and we locked that gold price in March of 2024 at $2,325. Today, or at December 31st, we had about 50,000 ounces of that gold hedge remaining. That gold hedge is gonna unwind through 2026 and into 2027. I think we're through it in Q2 of 2027. Ultimately, on our balance sheet, you can see that we do a mark-to-market adjustment that holds that difference.

That liability sits on our balance sheet. We recognize that loss on that derivative liability through the income statement in the year. A very significant amount, and we try to adjust it for adjusted earnings purposes. Again, we, as a company, have a policy that we would not like to hedge our silver. We have a small hedge in place from a collar, again from that project loan facility. We have a policy to try to remain unhedged. Of course, from a silver standpoint, if you're making an investment in a silver company, you believe silver price likely going higher. We wanna give that upside, and we feel like there's a lot of upside there in silver. We hedge the gold, which was a by-product, and again, we're through that mid 2027.

Soundarya Iyer (Senior Equity Research Associate)

Thank you, Dan, for all that color. Just one more on this Mexican peso appreciation, which was again a headwind on the costs this year, right? Any hedging or risk management strategy to, you know, cover that for 2026? Is there any sensitivity at, you know, what exchange rate does this currency, you know, start to impact meaningfully, margins or costs?

Elizabeth Senez (CFO)

Hi, Soundarya, this is Elizabeth. I'll take that question on the foreign exchange. As you see, we do have some Mexican peso hedges in place. I believe at the end of 2025, there were around 19 peso to the dollar remaining. We don't have very many left, and with lower prices, we haven't put many on recently. It's hard to hedge at 17 peso to the U.S. dollar. We are taking opportunities to hedge where it is appropriate for the Mexican peso. One of the advantages with adding Kolpa to our portfolio is that we have reduced our percentage exposure to the peso as well. The Peruvian sol is more steady for us. We do have that diversification as well.

Soundarya Iyer (Senior Equity Research Associate)

Thank you, Allison. I'll get back into the queue.

Dan Dickson (CEO)

Thanks for the question, Soundarya Iyer.

Operator (participant)

The next question comes from Cosmos Chiu with CIBC. Please go ahead.

Cosmos Chiu (Managing Director, Precious Metals Equity Research)

Hi. Thanks, Dan and team. Maybe my first question is, sorry, also on Terronera, but just I'm trying to kind of quantify it. You know, Terronera costs were fairly high in Q4, $50, $65, $70 an ounce. You know, Dan, you've talked about one-time costs, LNG plants and stuff. In 2026, you're guiding to $28-$29. I'm just trying to understand, you know, how it can drop in 2026. Is it gonna be more back-end weighted? You're gonna have some quarters that might be over $29, some quarters below $29 an ounce? If you have another quarter of $65, it'd be hard to average out to $28-$29 for the full year.

Dan Dickson (CEO)

Well, the good news is 65 was in Q4 of 2025.

Cosmos Chiu (Managing Director, Precious Metals Equity Research)

Exactly.

Dan Dickson (CEO)

Our guidance is only for 2026. We don't expect Q1 to be as elevated as it was in Q4. We've got some severance costs of moving off from various construction people in January, but we do expect that cost to decrease over the year. Q1 will be higher than Q2. Q2 will be higher than Q3. Q3 and Q4, we have higher grades coming in. On a per ounce basis, that cost per ton or that cost per ounce is gonna improve. The cost per ton won't become as drastic. I would point out that Q4 has the one-time expenditures of $16 million. Not necessarily one time, CapEx expense of $16 million-$17 million. In Q4, that includes one-time initial CapEx that flowed into Q4. We have that in Q1. We'll have less of that in Q2.

Q3, Q4, we should get pretty flattened out sustaining CapEx. That is gonna be the biggest driver of our cost per ounce increase at All-in sustaining costs.

Cosmos Chiu (Managing Director, Precious Metals Equity Research)

Yes.

Dan Dickson (CEO)

Similarly, our cost per ton, as we get more rhythm at site, we expect that to come in. We move from the temporary diesel gen sets to the LNG plant. That's cost improvement. There's a number of things that are gonna come through cost that are gonna come through the year. We've been saying out to the market and to analysts, "Look, Q1's our first quarter production, it's not indicative of what the future is gonna hold at Terronera." Again, we expect Q1 to be better, we expect Q2 to be better than Q1, and I think that's gonna come through.

Cosmos Chiu (Managing Director, Precious Metals Equity Research)

Great. Thanks. Maybe, you know, broader scale, can we talk a bit about Mexico, Jalisco? You know, certainly, some volatility in the area. Has it, you know, resulted or necessitated any change in security protocols on site at Terronera? Has it necessitated any kinda changes to systems in place, you know, to make sure that it's kinda, you know, in response to the situation? Then on top of that, can you talk about supplies on site, you know, consumables on site? You know, have you stocked up in light of what's happening in terms of fuel, in terms of consumables, in terms of spare parts? How should we look at it?

Dan Dickson (CEO)

No, it was a very fair question, considering what we saw this past week. Obviously unexpected. I think that was something we've never experienced in Mexico. Our biggest concern, obviously, first and foremost, is for our people and with Jalisco going to Code Red, shutting down Sunday night. The major thing about coming back from an operations is the supply lines out of Puerto Vallarta up to site. We're about an hour and 15, an hour and a half drive from Puerto Vallarta to site. Because of the topography of Terronera, we don't have a lot of storage space. We have about one week's supply of food for the camp, two to three days supply of water. We had a delivery of water on Monday that helped. Obviously, we're very concerned about diesel, and transporting that.

Going forward, I don't suspect we'll change our security around the Terronera mine. It will continue as is. We have to look at our protocols on shipments. Shipments coming up, shipments coming out, our concentrate shipments. We already have security protocols around all the shipments going out. Some of the shipments coming up, I think we'll just have to look at that, maybe beef it up a little bit. We don't expect a dramatic increase in security costs at this time. Of course, we have to monitor what this impact will have across the region if there becomes instability with all these groups in Mexico. As of right now, we don't have a huge change, just an increase of presence around our transportation lines.

Cosmos Chiu (Managing Director, Precious Metals Equity Research)

Mm-hmm. Great. Then maybe one last question, more of an accounting question here. With Bolanitos, the sale closing in Q1, is there any kinda accounting nuances or impact that we should be aware of for Q1? Is there gonna be some type of one-time gain or loss? Then can you talk about Mexican taxes as well? My understanding is that, you know, Mexico, cash taxes are higher on the first half or even in Q1. Is that what's happening here? You know, with the Terronera construction costs, the CapEx, does that help you offset some of those Mexican taxes?

Dan Dickson (CEO)

Yeah. Hold on. Can we just clarify your second question about Bolanitos taxes? You said something around timing of end of the year versus...

Cosmos Chiu (Managing Director, Precious Metals Equity Research)

Oh, yeah, overall. Yeah, overall, just more like Guanaceví. Sorry. I guess, number one, Bolanitos, the deal is closing or closed in Q1. Is there any accounting sort of nuances or entries or impact that we should be aware of?

Elizabeth Senez (CFO)

Yeah.

Cosmos Chiu (Managing Director, Precious Metals Equity Research)

Second part is just, you know, overall Mexico taxes, how we should look at it in terms of quarterly. Sorry, Elizabeth.

Elizabeth Senez (CFO)

Yeah, this is Elizabeth Soralis. I'll take that question. Yes, the Bolanitos sale closed January 15. And we will be recognizing that during our Q1 financials, obviously. And we are anticipating, as you saw, we sold it for approximately $50 million. For accounting, there's different adjustments to that, depending on the value of the shares that we acquired as a result. And then we were carrying it for around $25 million at the end of the year. We are anticipating an accounting gain on that in Q1. And that math can be done using our year-end financial statements. Your question about Mexico taxes. Guanaceví is paying Mexico taxes and pays installments regularly on those Mexico income profit taxes there.

Terronera, as you commented, does have construction costs, which are recognized as tax losses. As it starts to make taxable profits, those losses will offset those taxable profits during 2026. Depending on how the silver price goes, drives how quickly those losses will be utilized, when we will start paying income taxes in cash in Mexico for Terronera.

Cosmos Chiu (Managing Director, Precious Metals Equity Research)

Great. There's no big true up in Mexico, Mexican cash taxes in the first half of 2026, where I see that somewhere else in other companies, but I guess not here.

Dan Dickson (CEO)

No. On our sale of Bolanitos, we have historical losses that are designed or we can use that we won't have to pay a tax on our Bolanitos debt.

Elizabeth Senez (CFO)

At this point. That's our anticipation, yeah.

Cosmos Chiu (Managing Director, Precious Metals Equity Research)

Great. Great. Thanks, Dan, Elizabeth. Those are all the questions I have. Thanks a lot.

Dan Dickson (CEO)

Thanks, Oz. Good questions.

The next question comes from Alex Terentiew with National Bank. Please go ahead.

Alex Terentiew (Managing Director, Senior Mining Analyst)

Hey, guys. Thanks for taking my questions. I guess I was a bit slow with my fingers. A lot of questions already asked. Nonetheless, one question still for me here on Kolpa. Can you just clarify for me then, as it comes to that mine with permitting and getting 2,500, are you waiting for additional permits? Cause I thought 2,500 is kind of the ultimate expansion rate that you wanna get at. Based on your commentary guides, it sounds like you're gonna get there a lot sooner. Just wanted to make sure I'm clear on the expectations there.

Dan Dickson (CEO)

Yeah. We are getting there a lot sooner. I think it's a testament to the team that we acquired when we bought Kolpa. They're very confident people. In December, they received the construction permit to build out the Kolpa plant, which is really a expansion, the crushing facility, new crusher, ball mill to go to 2,500, then there's some additional flotation cells that need to be done. It, of course, expanding the mine underground. They received that construction permit. They're almost through that. We expect to be testing the ball mill relatively shortly, so let's say March. In our guidance, we did have 2,400 tons throughput for the average for the year. We've been running just over 2,300 over the last couple weeks.

There has been a lot of rain in that area, and we've battling how much rain there's been here in Q1, so it slowed us down a little bit from a production standpoint. The construction standpoint, like I say, we've been very impressed with how it's gone. From the construction standpoint, we can operate it, but we do have to get an operating permit, which generally comes a month to two months, maybe three months after the construction phase is done. We are allowed to test that circuit and go through that. Again, hopefully in Q2, we're approaching 2,500. The underground mine will be running around 2,300 tons per day. As we've talked about before, with the underground mine, it's opening up more faces, more employees, staff.

You're not gonna get a lot of economies of scale from the underground portion of it. The additional tons for the first half of the year will come from a lower grade pit that's within the area, and we'll try to fill that with some contractor ore as well. We are ahead upon the above ground surface. There's still some work to be done underground, we are in very good shape right now.

Alex Terentiew (Managing Director, Senior Mining Analyst)

Okay. Great to hear. Just one last question on Pitarrilla. A lot's happening there this year. Can you remind me of permitting timelines or kind of, you know, what you're doing to advance that this year and what news we maybe could expect, whether it's later this year or early next year on the permitting for that project?

Dan Dickson (CEO)

Yeah. I'll give a quick overview, and I might pass it over to Donald Gray, our COO. I mean, obviously we're spending $68 million at Pitarrilla. We really believe in the project. We like everything we've seen thus far. What makes Pitarrilla kinda special is the volumes that you can get out in such a tight space. There's a manto that's got 7 to 8 million tons of what would be ore once that feasibility study is complete, and then three feeder structures that come up and through it. We've been working on a mine plan, and that mine plan's gonna dictate the scale of the plant. Now, the plant has already been permitted. Underground mining's already been permitted. We're waiting on a tailings storage facility permit. It's gonna be a dry stack tailings. We've been working on the site.

We've been working on the engineering. We've been going back and forth with the state level SEMARNAT on how to submit this and how to submit it most efficiently. I think right now our projection is that we're aiming for a Q1 2027 permit to receive that tailings storage facility permit. Beyond that, there's additional permitting that's required, such as CFE for power, but that's something that we can work through during our construction timeline, as we did with Terronera. Of course, we'll need temporary power source during the construction. It's a question of when we can bring on power sources at the end of that. Don, I don't know if we wanna get in too much more detail of it, but there's a lot of permits that we've gone after.

We've spent the past 12 months working on that permit to make sure we're getting ahead of where we effectively were when we started building Terronera. Don, do you have any color you wanna add?

Donald Gray (COO)

Just that I think the permitting schedule really lines up well with the, with the project work that we need to do to finish the feasibility, get into the basic engineering, get the, like we mentioned in the press release, the long lead items or the major pieces of equipment on order so we can do the detail engineering and then head into construction. I think what you'll see is the engineering will be quite advanced by the time we go into construction, and we'll have a good idea on where the costs are and that kind of thing.

Dan Dickson (CEO)

I think the main gating item we're gonna get at Pitarrilla from a construction standpoint is that last permit. We'll be in very good shape, we feel, when we can get that permit.

Alex Terentiew (Managing Director, Senior Mining Analyst)

Great. Thanks for your time.

Dan Dickson (CEO)

Thanks for the questions, Alex. Much appreciated.

Operator (participant)

This concludes the question and answer session. I would like to turn the conference back over to Dan Dickson for any closing remarks. Please go ahead.

Dan Dickson (CEO)

Well, thank you, operator, and thanks everyone for attending our Q4 financial earnings call. Again, 2026 will be a big year for Endeavour. We're excited with what we can do with Terronera and getting that operation into a steady state, full rhythm by midyear. What Kolpa is gonna do for us and ultimately advancing Pitarrilla to take us to where we need to go, and that's, again, our goal to become a premier senior silver producer. Thanks a lot and have a good day.

Operator (participant)

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