Milestones are recorded only from a company's own dated disclosure. A milestone with no date shown is one we can confirm was reached but for which no date was disclosed — we don't estimate one. "Not yet reached" means exactly that, not that a date is missing. An "Expected" line likewise only ever reflects the company's own guidance (e.g. a study or permit decision targeted for a stated quarter) — most not-yet-reached milestones have none, and that absence means no such guidance has been disclosed, not that one is overdue.

Jurisdiction (40%)9/10
British Columbia: Fraser PPI 2025 is 74.28 of 100 (rank 31 of 68), which maps to 9 on this site's scale. British Columbia, Canada (primary asset) with a secondary Utah, USA asset — both top-tier, low political-risk mining jurisdictions.
Infrastructure (40%)8.6/10
A confirmed mill, confirmed road access, and a confirmed tailings facility at Cariboo Gold Project, British Columbia, Canada; grid power not yet researched, counted at a neutral 5/10 until established.
Nearby producing mine (20%)Not yet researched
No producing mine within 50 km in our reference list (nearest listed: Mount Polley (Imperial Metals Corporation), 62 km). That list doesn't cover every mining district yet, so a longer distance isn't scored as remote.
Acquisition Susceptibility
A relative ranking of how closely this company matches the profile of juniors that have actually been acquired — not a probability, and not a reason to buy. Acquisitions are rare: only a few dozen significant deals happen a year across a universe of thousands of juniors, so even a high score here describes a long shot. The strongest signal in the research, a producer that already owns part of the company, is scored from its disclosed strategic shareholders. A producer that is a joint-venture or earn-in partner on the project, rather than a shareholder, isn't captured yet.
How this score is built
- Disclosed pending dealSub-score: Not scored
No pending acquisition or merger disclosed (checked)
Not scored: having no deal in flight isn't held against a company.
Weight 26.25% - Producer's strategic stakeSub-score: Not scored
No producer holds a disclosed stake on file (holder register researched) See holders
Not scored: most juniors that do get bought had no prior toehold, so a missing stake says little either way.

Notable shareholders and insiders whose involvement is worth knowing about, plus what we're seeing from institutional/large-investor activity.
Double Zero Capital, a US investment firm, put roughly US$75M of cash in through a private placement that closed on 15 August 2025 and now holds 48,591,775 shares, 15.95% of the company (19.9% beneficially with the warrants its blocker allows, per its own SEC Schedule 13D/A of 26 May 2026), with warrants and a top-up right that let it go to a hard cap of 19.9%, plus the right to name a director. It has kept adding since -- another 2.4 million shares bought at US$4.78 in October 2025. On the day that placement closed, ten of the company's own directors and officers subscribed alongside it at US$2.05, including chairman Sean Roosen with 488,000 shares, and nobody at the company has sold a share. Condire Management, a resources-focused fund, holds a further 8.2%, and the register carries an unusually long tail of small dedicated gold funds -- Franklin, VanEck, Schroder, CPR, Konwave, Gabelli, Ruffer and others.

Osisko Gold Group, renamed from Osisko Development in July 2026, is building the 100%-owned underground Cariboo Gold Project in British Columbia's historic Cariboo mining district and also owns the Tintic project in Utah, where test mining at the Trixie deposit generates small-scale gold revenue. Its resource totals 3,832,798 oz of gold, combining Cariboo's 2,070,798 oz probable reserve (17.8 Mt at 3.62 g/t), Cariboo's additional measured and indicated resources reported exclusive of reserves, and 150,000 oz at Trixie, plus 1,915,000 oz inferred. The board made a formal construction decision on 14 September 2026, with the project already 22% physically complete, go-forward capital of US$717M (CAD 990M) funded by C$837M of cash and a US$450M Appian facility, and first gold guided for Q1 2029. The August 2026 go-forward update shows an after-tax NPV5% of US$1.68B and a 34.7% IRR at a long-term consensus gold price of US$3,570/oz, with a 10-year mine life averaging about 190,000 oz a year and an all-in sustaining cost of US$1,163/oz.
