TriStar Gold Inc.
TriStar Gold's flagship Castelo de Sonhos is a ~1.4M oz gold project with strong PFS-stage economics (40% after-tax IRR, US$603M NPV5%), but development is currently stalled by a Federal Prosecutor's Office legal challenge to its environmental permit (Licença Prévia). The permit remains formally valid and unrestricted while litigation proceeds, with management estimating a further ~US$1.5M in legal costs to potentially unlock construction licensing.

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.
Not in place: mill, tailings facility, grid power.
Jurisdiction (40%)5/10
Brazil is an established, large-scale mining nation generally, but this specific project faces active, ongoing legal/regulatory risk from a Federal Prosecutor's Office challenge to its environmental permit centered on indigenous-consultation adequacy.
Infrastructure (40%)2.9/10
No confirmed mill, confirmed road access, no confirmed grid power, and no confirmed tailings facility at Castelo de Sonhos Gold Project, Tapajós Gold District, Pará.
Nearby producing mine (20%)Not yet researched
No producing mine within 50 km in our reference list (nearest listed: Palito / Coringa (Serabi Gold plc), 227 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.

Insiders, Investors & Smart Money
Notable shareholders and insiders whose involvement is worth knowing about, plus what we're seeing from institutional/large-investor activity.
Four independent, named resource-specialist investment firms each hold meaningful stakes here -- Auramet Capital Partners (11.9%), Eric Sprott (8.9%), US Global Investors (8.6%) and Konwave AG (7.4%) -- with a fifth, Ixios Asset Management, just under 5%. That is an unusually deep and genuine specialist register for a company this size, even though roughly a fifth of the company is institutionally held overall, just short of the level that would add further credit here.

Reports, Presentations & Documents
TriStar Gold owns 100% of the Castelo de Sonhos gold project in the Tapajós district of Pará, Brazil, on which Royal Gold holds a royalty. Indicated resources contain 1,760,000 oz of gold, with no measured category, plus 740,000 oz inferred, in an estimate effective 4 October 2021, and the probable reserve is 38.7 Mt at 1.1 g/t gold. The May 2025 updated pre-feasibility study shows an after-tax NPV5% of US$603M and a 40% IRR at US$2,200/oz gold, with initial capital of US$296M, an 11-year mine life and an all-in sustaining cost of US$1,111/oz. Development is held up by a Federal Prosecutor's Office legal challenge to the project's environmental permit, which remains formally valid while the case proceeds.
