In brief

An executive analysis of the Cariboo Gold Project, detailing the path to production by Q1 2029 with an initial two hundred thousand-ounce annual output. The presentation highlights a robust financial position post-FID, emphasizing significant growth potential through aggressive conversion drilling, exploration of new deposits like Proserpine, and the strategic scaling of infrastructure within the historic Barkerville camp. The discussion provides key insights into construction progress, mill procurement, and competitive benchmarking against major Canadian underground bulk tonnage operations.

Key moments

  1. Osisko announces FID on Cariboo with US$717 million capex, first gold Q1 2029

    “We announced the final investment decision two weeks ago, and we updated our CapEx and our timeline to nine hundred and ninety million Canadian, seven hundred and seventeen million US.”

    The final investment decision and updated capex and timeline set the baseline for execution risk and valuation of Osisko's sole development asset.

  2. C$1.6 billion cash leaves roughly C$700 million freeboard over build cost

    “Our available cash position is one point six billion dollars. So we have about seven hundred million dollars of free board, which allows us to get very, very aggressive on our fast-tracking of the mine build”

    A fully funded build with significant excess liquidity removes financing risk and allows aggressive fast-tracking and expansion work.

  3. Mill already in the driveway, C$325 million procured pre-FID

    “Our entire mill circuit is in the driveway. We bought a mill from HudBay. It was never installed. It was supposed to go to Lalor, then they started to expand.”

    Securing the mill, fleet and substations ahead of FID de-risks the schedule and limits cost inflation exposure.

  4. Roosen positions Osisko against G Mining's market cap per ounce

    “West Dome gets about two point six billion dollars for a hundred thousand ounces of production. That same hundred thousand ounces a year at Lundin gets a four point five billion dollar market cap. And the winner of this prize is G Mining, getting eight point three billion dollars per hundred thousand ounces.”

    Management frames a clear re-rating thesis, arguing its US$1.7 billion market cap is far below peers with similar production and growth.

  5. Cariboo feasibility: AISC US$1,163, 1.8-year payback, NPV up to C$3.8 billion

    “At today's gold prices, this mine would put out about six hundred and thirty million a year in free cash flow. NPV at thirty-five seventy gold was two point three billion, three point eight billion at forty-three hundred.”

    The base-case economics on reserves alone show strong returns and cash flow before any upside from unscheduled resources.

  6. C$160 million drill budget targets doubling Cariboo to 400,000 ounces

    “So we have a hundred and sixty million dollar drill budget right now. We have sixteen drills on site now. We're going to thirty-five. And we're gonna do all the conversion of blue ounces from surface drilling”

    Converting 3.6 million ounces already passed by ramp development could double output within the same infrastructure, the core upside of the story.

  7. Proserpine discovery: wider open-pit target with no strip ratio near surface

    “It is fifty percent longer strike than Caribou and a hundred percent wider. Caribou is two to five hundred meters wide. This is five hundred to a thousand meters wide.”

    A second, larger open-pit deposit above the aquifer could materially change the scale of the Cariboo camp for shareholders.

We’ll have some knowledge of. What we’re gonna talk about today is the most recent announcements. We announced the final investment decision two weeks ago, and we updated our CapEx and our timeline to $990 million Canadian, $717 million US. And our timeline is to be first gold Q1 2029. However, there will be some test mining along the way. This project is located in Northwestern Quebec... sorry, British Columbia. [laughs] That’ll go down well.

We started on this project in 2015. It’s the old Barkerville heritage site and mining site. We have a consolidated land package here of about 1,550 square kilometers or just under 400,000 acres of land. This is the first time that this camp has ever been consolidated. It’s quite a historic camp. It started in 1862, and it was the big gold rush after the California forty-niners. As you guys know, my preference is always brownfield.

We went in here and started working on this. We produced a feasibility that we just updated now, showing a 200,000-ounce a year mine construction that’s underway now. We are 22% complete on the mine construction before announcing FID, and so we’re quite well advanced. We received our permits here in November of 2024, so we’re fully permitted for construction and for mining. We’re active on that grade now. We’ve done about $270 million of construction pre-FID.

Resource, it’s a 2 million ounce of reserves, 1.61 million ounces of measured indicated, another 1.8 million ounces of resource. So there’s 3.6 million ounces that are not in the feasibility and not in the plan yet, but that’s about to change.

We’re located about a forty-five-minute drive from the town of Quesnel on a paved road. Quesnel is 22,000 people. We’re about an hour and a half from the regional hub of Prince George, which is 110,000 people. So this is an on-infrastructure project. We also have five six ten to kilowatt US power from BC Hydro, which is a huge advantage in this diesel market. So we don’t have a lot of exposure to diesel other than a few haul trucks. Everything else is electric.

The way we looked at this project back in the day was, there’s a lot of historic mining here, over a thousand workings, couple of hundred placer mines in the valleys, and one successful underground mine at Cow Mountain, which produced 1.8 million ounces at an average of 17 grams. The mineral endowment here comes in the form of vein corridors that are long. We have 86 kilometers of strike length, of which we’ve explored 4.4 in detail, and we have another 6 kilometers underway now. So we consider exploration completion here at under 10%. This is a huge land package, and it’ll host many more mines after we get through with it.

The go-forward situation, we are investing $990 million Canadian, or $717 million US. Our available cash position is $1.6 billion. So we have about $700 million of free board, which allows us to get very, very aggressive on our fast-tracking of the mine build as well as the integration of the measured indicated inferred, which we refer to as the blue mine, with the pink mine being mine one. The goal here is to build two mines at roughly the same time within the same ore body, given it’s just conversion drilling required.

Construction is 22% complete, with first portal being in three kilometers, second portal collaring now, and we’ll get into which portion of the project complete. Detailed engineering is roughly at 40%. More importantly, procurements and commitments sitting at 325 million. Our entire mill circuit is in the driveway. We bought a mill from HudBay. It was never installed. It was supposed to go to Lalor, then they started to expand. So our mill is actually in hand in the driveway. It’s quite a big mill for what we need to do. And we also have our mining fleet procured, a lot of our substations and everything else. So our supply chain has been secured before doing this.

I think this is probably the most important slide for shareholders and equities at this presentation. If you look where we sit now, we’re about a $1.7 billion market cap, fully diluted. And if we look at this table, we have market cap on the vertical and ounces of production on the horizontal. So if you look at our friends from Wesdome, they sit at about a $5 billion market cap, and they produce about 200,000 ounces a year. And then a lot of the projects to the right are things that you’re familiar with. The analog to us, we believe, is G Mining. So they have 175,000 ounces a year production, so less than Wesdome, but they have a market cap of 15 billion. So three times the market cap of Wesdome with less production.

Now, why is that? They have a good project under construction in Guyana, a very credible management team, and they have quite a bit of upside in their growth portfolio. That is a very situated same scenario for us. So we’re coming online in 2029 at 200,000 ounces a year. If we’re successful in our conversion drilling, we’ll set the stage for significant increase in throughput at that point in time. Our target is to go from 200,000 ounces to 400,000 ounces within the same mine infrastructure that we’re building. So 30 kilometers of underground development will access that other mine, what we refer to as the pink mine and the blue mine.

Our goal is to land somewhere over in the right-hand side of the dotted line box. You see our friends at Lundin producing at around 500,000 ounces a year with a $24 billion market cap. Alamos at $21 billion with a little over 550,000 ounces a year. Artemis is in there at 5.4 billion, around 380,000 ounces a year. And then they’re going up to 550,000 ounces a year.

One of the interesting things that came out of this work is if you look at the top right-hand corner, West Dome gets about $2.6 billion for 100,000 ounces of production. That same 100,000 ounces a year at Lundin gets a $4.5 billion market cap. And the winner of this prize is Jimin, getting $8.3 billion per 100,000 ounces. So one of these things is not like the other, and we feel that that’s what we wanted to call your attention to because this is what we are building now.

So the feasibility, again, just based on the 2 million ounces of reserves, 190,000 ounces a year over ten years, 202,000 ounces for the first five years. Ten-year mine life with production starting at Q1 2029. All in sustaining class quite low at $1,163 an ounce. $717 million US go forward capital, so 900 Canadian... call it a billion Canadian. And free cash flow life of mine at around $362 million a year based on $3,700 gold. At today’s gold prices, this mine would put out about 630 million a year in free cash flow. NPV at thirty-five seventy gold was 2.3 billion, 3.8 billion at forty-three hundred. 34.7% internal rate of return at the lower gold price of thirty-five fifty, closer to spot, just under 43%.

Ounces that are not in the mine plan, the 1.6 million ounces of measured and indicated, and the 1.86 million ounces of inferred. They are outside of the mine schedule right now, but not outside of the mine development. So if we look at the go-forward date at forty-three fifty gold, the NPV would be about 3.2 billion. Payback is about 1.8 years, so quite quick. And annual free cash flow the first five years is 642 million. So this thing makes a lot of money if we just do the 200,000 ounces a year mine.

A bit about the schedule. So I won’t go too much into detail because we are in construction. A lot of these things are active as we speak, completing almost all the tasks by the end of 2028 with a mill ramp-up starting at the end of 2028. So that’s about a twenty-nine-month mine build from where we sit today.

The $270 million that we spent pre-FID, what we did achieve is a 350-man camp that all has individual rooms with every room has a washroom and one bed, so it’s individual lodging. On the right-hand side, you can see the waste dump, which is obviously key to being able to hard push on the underground development. We’re at about 90% complete on that. And then at the bottom, you can see the settlement control pond and then the water treatment plant, one of two, is complete and commissioned. So a lot of the more boring stuff and some significant earthworks are actually behind us. In an old mining camp, the earthworks are always one of the hardest parts in case you find an old stove or an old razor or something under your mill foundation. So we’ve answered that.

This is the aerial shot, the big one, shows the entire main area of development. The mill site is actually the small area in the top left. That’s nearing completion now. We’re at about 90% there to start the concrete. On the right-hand side of that dotted line is the actual second portal, the main portal. So we’re coloring that as we speak. And then all that area down below is our laydown yards, our stockpiles, and the rest of it. And you can see on the right-hand side some rusty stuff. That is the tailings from the previous operation that finished in 1960, having produced 1.8 million ounces at 17 grams.

The bottom left-hand side is a little bit more of a blow-up of the face for the second portal. This will step on the gas. It will triple our underground faces for development. We are building a very large underground infrastructure, five and a half by five and a half meters. We’re using fifty-ton haul trucks to set the stage for the mine expansion that hopefully we’ll have figured out and announced by the end of the construction.

The key story for today is this. When you look at the plan view here, the entire feasibility and all the economics that I just showed you is based only on the pink ounces. As you can see, the blue ounces are far more numerous than the pink ounces. There’s 3.6 million ounces total in the blue. And if you look at the ramp access, we’re often driving by blue ounces to get to pink ounces. So we have a $160 million drill budget right now. We have sixteen drills on site now. We’re going to thirty-five. And we’re gonna do all the conversion of blue ounces from surface drilling as opposed to wait until we’re underground. And that will set the stage for a much bigger mine plan.

So we essentially double the number of stopes available within the existing infrastructure through that infill drilling and set the stage for a much more robust push towards extending the production above the 4,900 tons a day that we are permitted for. We are on a permitting track to expand from 4,900 tons a day to significantly more of that. The goal would be 15,000 tons a day. This is the mine plan we’re building. It will support 15,000 tons a day with the conversion. The current mine plan is built for 7,800 tons a day on just the pink ounces. So for 4,900 tons a day, we have 50% over capacity in the number of stopes that we have available at any time.

Because this is a ramp access mine, we have a lot of flexibility. Instead of relying on a central shaft, we’re building four different portals from surface that will access the mine, so it will act like four independent mines that we have. If one’s got a problem, we still got three left to go. And having that ramp access also allows us... Stage two will be to twin some of these ramps and put in conveyors, which is why we think that the thing can push pretty hard well past the 5,000 ton a day limit.

This is the long section of the drilling that we’ve done so far, 4.4 kilometers, which is the length of the deposit and the length of the mine plan. The red represents all the resources, the 2 million ounce reserves, and the 3.6 million ounces. We are only down to an average depth of 350 meters. You can see some of the red dots. We’ve actually drilled down past 1,100 meters in a lot of these cases. So 350 meters gets you 5.6 million ounces total resource. So if we took it down to 1,100 meters, you would have a shot at 15 million ounces, and if you took it down to 1,500 meters, you’ve got a shot at 22 million ounces, and down to 2,000 meters, you’re at 30 million ounces. So the drilling that extends that at depth is going on as well throughout the next twenty-four months to demonstrate that that is a realistic expectation in this deposit.

We’ve executed just under 900,000 meters of our own drilling. There is no historic drilling involved in any of the work that we’ve done. We’ve redrilled it to a CISCO standards with oriented core over the last six years to very high standards and with dry road control accuracy to generate a mine plan that is accurate. We’ve gone back, and we’re doing the infill drilling to tie in that drilling to make sure... We’ll drill from other angles to make sure the accuracy of our stope design. So this is not a mine that was on PowerPoint anymore. This thing is in action being built, and the integration of this project took us about 2017 to understand the geology model here. If you look at that right-hand bubble, it actually shows how the vein corridors are made, essentially an accordion opened up and fluids coming through those cracks. So that’s a pretty important part of the story.

And we now have a new discovery on the other side, but before we get to that, the analogs to compare this to, for anybody that’s not familiar with Canadian underground bulk tonnage mining: we sit at 3.62 grams head grade, 190,000 ounces a year production. All-in sustaining cost eleven fifty-six with 4.4 kilometers of strike length, only down to an average depth of 350 meters.

If you compare that to Alamos’ Young-Davidson, they’re about 1.7 grams lower than we are, and they’re about 1.1 kilometers of strike. So they have to go down for their ounces, and they’re down to a vertical depth of roughly 1,500 meters already. So they’re shaft relying and constrained by the capacity of their lifting equipment. We, with the four kilometers, we can just keep adding portals to increase production. And they’re 1.94 grams, and so you could actually put Young-Davidson in our footprint four times and add a gram and a half. They’re currently producing 153,000 ounces a year at just under two grams, at a six sixteen thirty-three. So if we put that in four times with us, that would be 600,000 ounces a year on their grade and much more on our grade.

Goldex is another good mine to look at. It’s the lowest grade underground mine in Canada. It’s about 800 meters long and at about 400 meters wide. It operates at 1.4 grams underground, so we have about a two-gram advantage on them. So 1.4 grams right now with gold at about 140 grams, call it 200 bucks a ton of rock. Our rock NSR is between four fifty and five fifty US a ton. They are constrained by width. They’re only 800 meters long. You could put their mine in here five and a half times and double the grade, and you still wouldn’t have it. So they’re producing 126,000 here at AISC thirteen forty-three, at less than half our grade.

The other mine to look at is the LaRonde mine, which was the company maker asset, and when I built Canadian Malartic, LaRonde was the biggest mine in Quebec at 350,000 ounces. Canadian Malartic came on at 670,000 ounces. But this was the company maker asset that had built Agnico. It’s now 1.5 kilometers in the shallow zone, averaging 4 grams, so a little bit higher grade than us, but their deeper zones right now are over 11,000 feet deep, over 3,200 meters, and all with shafts and everything else at 7,700 tons a day to produce about 345,000 ounces a year. So we’re not that far off their grade, but our mining is much simpler, and our ability to scale by adding ramps significantly higher than anything you could do with LaRonde now. So those are three mines that I think you should think about when you look at this project. If you take LaRonde, we can put LaRonde, Goldex, and Young-Davidson in our strike length and still have room to move.

The big story that we are gonna hear a lot about over the next eighteen months, twenty-four months: we have Cariboo on the left, which you can see, 4.4 kilometers of strike length. We have a couple of other deposits that we haven’t put into the mine plan yet, Marcerville Mountain and Williams Creek. But the big one that we’re working on right now is called Proserpine. As you can see, Cariboo has a valley, a lake, and a town in the bottom of the valley. Proserpine is up on top of the mountain, well above the aquifer, and is perfect setting for an open pit, and it is 50% longer strike than Cariboo and 100% wider. Cariboo is 200 to 500 meters wide. This is 500 to 1,000 meters wide.

We have forty drill holes into this right now. We drilled some in the past. But we see this being a much larger Cariboo that’s relatively free of any encumbrance from mining because it sits on the top of the hill. In the first 100 meters, there’s no strip ratio. So this will be a very big change for shareholders as we get into it. So we have sixteen drills on site, and there are now three underground, thirteen on surface, and we’re going to thirty-five drills. We have a $160 million drill budget. So the title of this season is called Drill to Thrill for All Other Matters Drill Blast.

This is the overall property package, 86 kilometers of trend, fully documented through ground truthing, historic workings, just under 400,000 acres. We compared it to the LaRonde Camp, the Malartic Camp. Our land package is 1,550 square kilometers. The entire Val-d’Or Camp, including Canadian Malartic and LaRonde, is only 1,400 square kilometers. So this is game on for a big project. Anybody who’s got any more questions, please give me a call or cut me out of the crowd. But we now have 1.3 billion US dollars to build a 700 million mine and a $160 million drill budget. So this will be a pretty exciting story for the next three, four years.

We may have time for one very quick question, if anybody from the audience. Otherwise, maybe, is there any key components on the construction that still have pricing variability? What should we be concerned about, and what’s the most important ones that are already taken care of, please?

Most of the stuff that I would have worried about are done now: earthworks and pioneering and getting camp set up and getting permits for all the other ancillaries. We’re focused keenly mostly on the underground. We’re trying to double our chances by doing the conversion drilling, which would double the ounces available, the stopes available per kilometer, and then adding a couple more ramps in and going to the conveyor system probably earlier than we might have thought originally.

Perfect. Sean, thank you very much. I appreciate it.

All right. Good luck everybody with your investments. [audience applauding]
