Thank you, Jericho. Welcome, everyone, and thank you for joining Teseco's 2025 Fourth Quarter and Annual Results Conference Call. The news release and regulatory filing announcing our annual financial and operational results was issued yesterday after market close and is available on our website at tesecomines.com and on CDAR+. I am joined today in Vancouver by TSECO's President and CEO, Stuart MacDonald, TSECO's Chief Financial Officer, Bryce Hamming, and our COO, Richard Tremblay. As usual, before we get into opening remarks by management, I would like to remind our listeners that our comments and answers to your questions will contain forward-looking information, and this information by its nature is subject to risks and uncertainties. As such, actual results may differ materially from the views expressed today. For further information on these risks and uncertainties, I encourage you to read the cautionary note that accompanies our fourth quarter MD&A and the related news release, as well as the risk factors particular to our company. These documents can be found on our website and also on CEDAR+. I would also like to point out that we will use various non- during the call. You can find explanations and reconciliations regarding these measures in the related news release. And finally, all dollar amounts we will discuss today are in Canadian dollars unless otherwise specified. Following opening remarks, we'll open the phone lines to analysts and investors for questions. I'll now turn the call over to Sir for his remarks.

Great. Okay. Thanks, Brian. And good morning, everyone. Thanks for joining our call today to discuss our 4-4-25 annual results which were released yesterday. As usual, I'll start by providing some comments and additional detail on the operational aspects of our business, and then Bryce will review the recent financial performance. So I'm going to jump straight to the exciting news that we announced yesterday. Florence Copper is now producing copper, as of just a few days ago when we turned on the electro-winning circuit. Copper is now being plated, and we're just a few days away from harvesting the first cathodes. This is a great achievement for everyone at Tesico. and especially the construction and operating teams at Florence. As we've talked about, wellfield operations commenced in the fourth quarter, so we've actually had solutions flowing in the commercial wellfield for about three months now. Initial results from the wellfield have been very positive, as we've been able to achieve higher injection flow rates than expected in these first few months. As a result of those higher flows, the acidification of the ore body has been faster than planned, and the grade of copper recovered in solution or PLS, has actually ramped up faster than expected. So it's still early days, but the initial leaching results have been quite positive. And actually, our PLS grade was high enough to begin copper production several weeks ago, but the commissioning of the SXEW plant took a few weeks longer than planned. We're expecting Florence to produce approximately 30 to 35 million pounds of copper this year. And by the time we report first quarter earnings, we'll be in a good position to provide some operating metrics in terms of flow rates, PLS grade, and production from the initial wells. A key factor in the ramp-up will be our ability to expand the well field and bring on new wells through the year. Drilling resumed in the fourth quarter, and there are now three drill rigs running. It's taken some time for the new drilling crews to get ramped up, We have a fourth drill rig being added in the next week or so and expect to see improved drilling productivity going forward. Before we turn to Gibraltar, I'd like to start by commenting that safety is a core value at Taseco. Nothing is more important than ensuring that the people who work at our operations go home each day the same way they arrived. In November, a tragic accident occurred at Gibraltar that resulted in the death of a contract worker. We're deeply saddened by the loss of a colleague and again offer our condolences to the co-workers, friends and family of the individual. Findings from that incident are in the process of being reviewed with employees on site. In terms of production at Gibraltar, in the fourth quarter we saw copper head grades increase to 0.26% and recoveries of 81%, which led to 31 million pounds of copper production. So it was a strong production quarter. The higher grades and recoveries were slightly offset by throughput, which was about 8% under design capacity for the period due to unscheduled mill downtime. Molybdenum production was 800,000 pounds and also benefited from higher grades and recoveries. Copper and moly production for the quarter was the highest level of 2025 as we expected it would be. And for molybdenum, it was actually the best production quarter in the history of the mine. With higher production, our total operating costs dropped to 247 US per pound in Q4. For the year, Gibraltar produced a total of 98 million pounds of copper and 1.9 million pounds of molybdenum at a cost of 266 per pound. Production was heavily weighted to the second half of the year as we mined deeper into the connector pit to access higher grades and better ore quality in the third and fourth quarters. Looking ahead to 2026 mining operations are much better situated in the connector pit so we expect higher annual production and much less quarterly variability than last year. We are, however, taking a more conservative view on copper grades, due to the impact of small higher grade zones that have not been realized through our mining so far in the connector pit. Over the last 18 months, we've also encountered more oxide and supergene and transitionary ore in the connector pit than we originally expected. The oxide ore has been stacked on leach pads and would be processed through the Gibraltar SXEW plant. But the supergene ore goes through the concentrator with lower recoveries. For 2026, we're expecting average recoveries between 75% to 80%. And that's really a similar level to what we saw in the second half of 2025. Taking all of this into account, we're expecting Gibraltar to produce 110 to 115 million pounds of copper this year. And given that the connector pit will be the primary source of ore for the next three years, we expect annual production will remain at the same range, plus or minus 5%, through the end of 2028. With copper prices now roughly 25% higher than last year's average price, we are well positioned to benefit from our copper price leverage supported by higher production from Gibraltar and production growth at Florence. Tight supply due to global mine disruptions combined with strong demand from traditional end users and new demand from AI data centers and grid modernization all support continued strong copper prices. So Teseco is very well positioned for cash flow growth in the future. We also have significant long-term optionality and value in our other projects. And in 2025, we achieved some significant milestones at both Yellowhead and New Prosperity. The new technical report from Yellowhead confirmed strong economics, and we will continue to advance the project towards an ultimate construction decision and begin unlocking the net present value. And talking about leverage to copper, that NPV also benefits from a strong copper price environment. When we published our report in June, we used a price of $4.25 per pound, which gave us a $2 billion NPV. At today's pricing, that's more like $4 billion after tax NPV or even higher. So the project's getting a lot of attention from potential partners, and when you consider the lack of large-scale open pits, copper projects in North America that can be brought online in this time frame you know these opportunities are very rare so it's a great opportunity great asset I think for the company going forward permitting efforts are very active and we continue to engage with the local communities and open houses in recent months with no major issues arising so far our yellowhead project team is also preparing the detailed project description that will be filed later this year So 2026 promises to be another busy and productive year on many fronts. And with that, I'll turn the call over to Bryce for some commentary on the financials.

Thank you, Stuart. And again, welcome, everyone. I'll give some further color on some financial details before we get into any questions. Total copper sales for the fourth quarter were 32 million pounds, including 800,000 pounds of cathode from Gibraltar's SXCW facility at an average realized price of 513 per pound. including $25 million of revenue from Mali. We generated revenue of $244 million in the quarter. For the year, revenues of $673 million were recorded for the sale of 99 million pounds of copper and 1.9 million pounds of Mali. The average realized copper price in 2025 was robust at $461 US dollars per pound, and we benefited from a generally weaker Canadian dollar. Quarterly and annual revenue are the highest Teseco has ever recorded, now that we own 100% of it. For the quarter, we recorded net income of $4.5 million, or $0.01 per share, and on an adjusted basis, after removing unrealized marks on our liabilities, which are tied to the higher profit price and other unrealized items, it was $42 million, or $0.11 per share, of adjusted earnings. Adjusted EBITDA in the fourth quarter was $116 million as compared to $56 million in the same quarter in 2024 and $62 million in Q3. For the year, adjusted EBITDA was $230 million, slightly higher than the prior year. So production in Q4 contributed to half of our annual earnings. Also for the quarter, cash flow from operations was $101 million, which was significantly higher than previous quarters. with Gibraltar contributing free cash flow of $72 million. For the year, $220 million of cash flow from operations was generated from Gibraltar. Overall, financial performance was strong and definitely benefited from the higher copper pricing in the second half of the year with improved production and sales levels. I will remind everyone that we do have copper price collars in place that we put in place in place to support our Florence Copper project development and project finance. It has a ceiling price of 540 per pound until the end of June, which had a market year end of $22 million. For Q3 of 2026, we have added copper price collars that have secured a minimum price of 475 per pound for 8 million pounds per month in the third quarter, and that have much higher ceiling prices of 750 and 850 per pound. As we move beyond the ramp-up of Florence, we do plan to revert to our longer-term strategy of just buying copper put options over shorter-term time horizons and leaving the entire upside to copper price open with two mines running. Now on to Florence, where things have been going very well, as Stuart mentioned. We completed the capital project in the fourth quarter. Capital spending decreased dramatically from prior quarters to just $8 million in the quarter as construction activity winding down. Final capital costs for the commercial facility were $275 million U.S., which was approximately 3% over the revised budget from early 2024 when we started construction. In the fourth quarter, $60 million of site operating costs and commissioning costs were capitalized for Florence. With cathode production now underway, we'll begin expensing operating costs, which today have been capitalized significantly still in the first quarter. We ended the year with a cash balance of $188 million plus our undrawn revolving credit facility for $110 million U.S. So that brings our total liquidity to a very strong $340 million. With strong cash flows expected from Gibraltar in 2026 and the development capital spending behind us at Florence, our balance sheet will improve throughout the year in the current copper price environment. As Florence Copper begins to provide cash flow as their second operating line, our credit rating will naturally re-rate, and we will prioritize de-levering the balance sheet with our excess cash later this year. And with that, operator, I'll open the lines for questions. Thank you.

Thank you. And now begin the question and answer session. If you have that and would like to ask a question, please press star 1 on your telephone keypad to raise your hand and join the queue. If you would like to withdraw your question, simply press star 1 again. If you are called upon to ask your question and are listening via speakerphone on your device, please pick up your handset to ensure that your phone is not on mute when asking your question.

Again, press star 1 to join the queue. Our first question comes from from PD Securities.

Please go ahead.

Thanks very much. Congratulations, guys, on Florence. Just a quick question here. What should we expect for CapEx and stripping this year?

Yeah, hi. It's Bryce. Yeah, I think with respect to CapEx, Last year, we had $80 million of capitalized strip, and we'll have slightly less this year as we're past some of the heavier strip sequences of Gibraltar. We'll see that come down to some extent. I think we have, on the sustaining CapEx side as well, the main thing is some additional tailings work that we're going to do this year, but that should also be... be contained. So nothing really unusual compared to some of the capital projects that we've had in prior years, like the Crusher move and so forth.

Great, thank you. And just one follow-up. How should we think about grade and throughput this year as it relates to your guidance? Well, I think, I mean, I think throughput we're always, you know, expecting to achieve

something in the range of design capacity, which is 85,000 tons a day, just over 30 million tons for the year. That's always the goal, and I think we've been successful. I think last year we achieved that. Grade, as I noted in my remarks, I think the reserve grade in the connector pit is 0.25, but what we've actually seen is the impact of some that reserve grade being skewed a little bit by some smaller high-grade zones. So we're being a little more conservative now in our expectations and expecting something potentially 5% to 10% lower than that.

So that's generally how we get to the guidance figures. Great. Thanks so much.

Our next question comes from Dalton Barreto from Canaccord Gen. Please, go ahead.

Thanks. Good morning, guys, and congratulations on Florence. And maybe I'll start there. Steve, as you're thinking about the ramp up on a go-forward basis now, how do you think about some of the rest? What are you keeping your eye on? Is it purely a function of well-field expansion? sort of concerned around homogeneity of the ore body. What are you keeping an eye on? Thanks.

Yeah, I think, I mean, obviously we're very pleased with the initial leaching results, right? And our ability to acidify new sections of the well field, get our PLS grade up. Obviously, we still have a lot of work to do to stabilize the whole process from well field through to actually played in copper so it's still very much a ramp up but you know early days but so far so good one thing I would say on the ramp up as you noted is definitely the drilling we do need to add new wells and when our mining plan we plan to add 80 to 100 new wells essentially every year for the next decade or longer so that's normal course going to be normal course at Florence, and that's an important part of the ramp-up. So, yeah, I don't know, Richard, if you have any comments.

Yeah, that's exactly, Stuart. Really, the thing we're watching closely is just the drilling performance and how the drilling is moving forward to bring on the new wells that we know we need as the production profile increases. Okay.

That's great, guys. And then maybe switching gears to Gibraltar. Can you talk a little bit about some of these issues you're seeing at the connector pit? I mean, what happened? Why aren't you picking up some of those high-grade zones? And maybe why some of the higher oxide and super-G material was maybe missed in the reserve?

Yeah, I think the easiest way to explain the high-grade zone is there's very high... There's kind of isolated drill hole, exploration drill hole results that are skewing the geological model, and we're in the process of kind of going through and, I guess, reinterpreting those drill holes, and in turn, it's going to downgrade the grade that we're encountering because we've mined through a few of those areas and not realized the grade that we expected, so we know those I would describe as ultra-high-grade pockets that are in the model need to be adjusted, which we're in the process of doing, and that's why we provided the guidance we did today.

And what about on the supergene and oxide material? It sounds like you're seeing more of it than you anticipated.

The oxide has been a positive that's allowed us to go to the oxide dumps and will actually allow us to run the SXCW plant longer than was originally envisioned. It's actually a good case scenario from an overall cathode production perspective. The supergene-hypogene kind of transition zone is, you know, there's interpretations of where that is. And, you know, in some places we've seen it not be properly reflected where the supergene actually is more than we have in the model. And those things are, we just need to adjust it to reflect the reality of what we're seeing.

Got it. Thanks. If I can just squeeze in another one here just on the portfolio. I mean, in this environment, clearly, Yellowhead and Prosperity are very valuable assets, and Niobium looks like it's going to have its day in the sun as well. Stu, how are you thinking about next steps for each of those?

Well, Yellowhead is very much a permitting project now. We've got a lot of work underway. We have a big, good, solid team in place that's working closely with the regulators and with the community. You know, we've got solid relationships, I think, there. I think in the coming, you know, over the next year or two, I think we're going to probably advance some discussions with potential JV partners there. You know, there's a lot of interest, as you would expect in this copper price market. And as I mentioned in my remarks, this is a pretty unique opportunity with a large large-scale open pit Greenville project in North America there are very few of these out there that could be brought on in the next you know five years four or five years so so that's You know heading on a path. I think on a good path to realize you new prosperity obviously the big news last year we signed our agreement with the Chilcot Nation in BC and I think generally we all know that is an incredibly valuable deposit, but to really unlock it and move forward, we need the consent of the Chilcot Nation, and that was clarified obviously in our agreement last summer. So we're allowing their land use planning process to move forward, and we'll be patient and respect that process, but obviously still a very interesting asset for us in the future. Yeah, and then Alley Niobium you mentioned. It's obviously one that's a little bit off the radar perhaps for some of our investors, but it's a very large, open, pittable niobium deposit in northern BC. It's one of the largest undeveloped niobium deposits in the world. And we continue to work on that in the background. We don't talk a lot about it, but we do have a strong... technical team that is pushing forward and doing some very good work. And we're also expanding our work and looking for potential offtake partners and partners to help us develop that project. So lots of happening there. Yeah, so it's good. We've got, I think, one thing about our company. We've got, obviously, immediate growth with Florence, but we've got a lot of longer-term projects options as well in our portfolio. So pretty exciting, we think.

That's great, Stu. That's awesome. Thank you.

Thanks, Dalton. Again, if you would like to ask a question, press star, then the number one on your telephone keypad. You're going to pause for a moment to compile the questions. There are no further questions at this time. That concludes the question and answer session. I would like to turn the call back over to the TSECO management for closing remarks.

Great. Okay. Well, thanks again, everyone, for joining. Yeah, we will continue to keep you updated as the Florence ramp-up progresses and obviously look forward to talking again next quarter. Thanks.

This concludes today's conference call. Thank you for joining. You'll be now disconnected.
