Panoro Minerals Ltd.
Panoro Minerals holds 100% of the Cotabambas copper-gold-silver porphyry project in the Apurimac region of southern Peru. The current NI 43-101 mineral resource estimate (AGP Mining Consultants, QP Paul Daigle P.Geo., effective 20 November 2023, filed 29 February 2024) reports 507.3 million tonnes Indicated at 0.34% Cu, 0.20 g/t Au, 2.42 g/t Ag and 0.43% CuEq, plus 496.0 million tonnes Inferred at 0.27% Cu, 0.17 g/t Au and 0.36% CuEq, at a 0.15% CuEq cut-off within an optimized pit -- roughly 1.0 billion tonnes containing about 12.5 billion pounds of copper-equivalent, including a higher-grade component of 129.0 Mt Indicated at 0.70% Cu and 0.44 g/t Au at a 0.5% CuEq cut-off. A preliminary economic assessment was completed in 2015 (updated 22 September 2015: after-tax NPV of US$683.9 million at a 7.5% discount rate, 16.7% IRR, 17-year mine life at 80,000 t/d averaging 155.1 million pounds of copper a year, US$1.53 billion initial capital, on US$3.00/lb copper). That study has never been formally withdrawn, but it was built on the 2013 resource model that the 2023 estimate replaced, and Panoro no longer presents it: the company's stated plan is to fold the updated mine plan into a NEW preliminary economic assessment and then a prefeasibility study, with metallurgical testwork underway and initial results expected in Q4 2026. Stage is therefore held at resource definition rather than PEA. Drilling in 2026 was expanded from an initial 15,000 metres to 45,000 metres after a C$21.0 million financing in May 2026, targeting five rigs by the end of Q3; hole CB-228 returned 317.6 metres of 1.04% CuEq including 66.1 metres of 1.92% CuEq. Wheaton Precious Metals holds a 2016 early-deposit precious-metals purchase agreement over the project (US$140 million for 25% of payable gold and 100% of payable silver).
Notable vs. Peers
- 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 top-tier copper resource base and long mining tradition, but the Apurímac region specifically has a history of community and social-license friction around large-scale projects, adding risk versus more established Peruvian mining regions.
Infrastructure (40%)2.9/10
No confirmed mill and no confirmed tailings facility at Cotabambas Copper-Gold-Silver Project, Apurímac, 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 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.
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

Insiders, Investors & Smart Money
Notable shareholders and insiders whose involvement is worth knowing about, plus what we're seeing from institutional/large-investor activity.
The one piece of outside validation Panoro has is a real one, but it is indirect: Wheaton Precious Metals committed to an early-deposit precious metals purchase agreement over the Cotabambas project, under which it will pay up to US$140 million for 25% of payable gold and 100% of payable silver. Wheaton's technical team had to underwrite the project to sign it, and it has kept making the staged early-deposit payments -- the seventeenth landed in 2023. But Wheaton buys future metal rather than shares, so this is not a shareholder vote, and no fund, producer or insider position is on record.

A 2015 preliminary economic assessment was based on an older resource model, and the company plans a new preliminary economic assessment and then a pre-feasibility study, with initial metallurgical results expected in the fourth quarter of 2026. The 2026 drill programme was expanded to 45,000 m, and hole CB-228 returned 317.6 m of 1.04% CuEq. Wheaton Precious Metals holds a 2016 agreement to buy 25% of the project's payable gold and 100% of its payable silver.
