Regulus Resources Inc.
Regulus Resources is advancing the AntaKori copper-gold-silver project in Cajamarca, northern Peru, immediately adjacent to Compañía Minera Coimolache's operating Tantahuatay mine. Under a collaboration agreement with Coimolache, the companies completed an integrated Coimolache Sulphides/AntaKori mineral resource estimate on 30 June 2026, whose results can only be released by mutual agreement and which Regulus does not expect to be made public; AntaKori's own resource is 250 million tonnes Indicated at 0.48% Cu, 0.29 g/t Au and 7.5 g/t Ag plus 267 million tonnes Inferred at 0.41% Cu; the company is thinly capitalized with approximately C$5.2 million in cash funding continued technical work.
Notable vs. Peers
- Financials score of 2.8/10 is weaker than the peer average of 5.6/10.
- Jurisdiction risk score of 5/10 is meaningfully riskier than the peer average of 7.7/10.
Lifecycle Milestones
Not in place: mill, tailings facility. Not yet determined: road access, grid power.
Jurisdiction (40%)5/10
Peru has a long mining tradition and a top-tier copper resource base, but a history of community/social-license conflicts and political instability at the national level add meaningful risk versus top-tier jurisdictions.
Infrastructure (40%)2.9/10
No confirmed mill and no confirmed tailings facility at AntaKori Copper-Gold-Silver Project, Cajamarca, Peru; road access and grid power not yet researched, counted at a neutral 5/10 until established.
Nearby producing mine (20%)Not yet researched
No project coordinates on file yet, so distance to a producing mine can't be measured.
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 stake on file; largest strategic holder is Nuton LLC (15.98%) See holders
Not an operating producer, so it isn't the toehold-then-takeout pattern the research documents; a missing producer stake isn't held against a company.
Weight 25% - Distance to a producing mineSub-score: Not yet researched
Distance not yet researched: no project coordinates on file
Distance can't be measured without coordinates, so excluded rather than counted as far.
Weight 22.5% - Lifecycle stageSub-score:3.5/10
Stage: Resource Definition
Feasibility and permitting score 10, where deals cluster, and production 5.5; earlier stages score less, down to 1 at grassroots.

Insiders, Investors & Smart Money
Notable shareholders and insiders whose involvement is worth knowing about, plus what we're seeing from institutional/large-investor activity.
Rio Tinto is a shareholder here. Its Nuton venture -- the group's copper-leach technology arm -- put C$20,460,153 into Regulus on 30 January 2023, buying 20,058,974 shares at C$1.02, and Rio Tinto/Nuton is now recorded at 15.98% (May 2026 circular) with its own board seat via Nuton's CEO as nominee director. For a copper project, having the world's second-largest miner's leach-technology team decide to own the equity is about as pointed a technical endorsement as a developer can get. Route One Investment Company, a US$4.7B value fund, is larger still at 21.63%, and Osisko Gold Royalties has separately committed US$17.5 million at the project level.

Reports, Presentations & Documents
Regulus Resources is advancing the AntaKori copper-gold-silver project in the Cajamarca region of northern Peru, immediately adjacent to Compañía Minera Coimolache's operating Tantahuatay mine. Under a collaboration agreement, Regulus and Coimolache completed an integrated mineral resource estimate covering the Coimolache sulphide zone and the AntaKori deposit on 30 June 2026. That estimate, and any preliminary economic assessment the parties may agree to pursue, can only be released publicly with the agreement of both parties and regulatory approvals, and the company has given no timeline. Until then, the published resource for the project is AntaKori's own February 2019 estimate, 250 Mt Indicated at 0.48% Cu, 0.29 g/t Au and 7.5 g/t Ag plus 267 Mt Inferred at 0.41% Cu, and no economic study has been published.
