Unico Silver Limited
Unico Silver holds 100% of the adjacent Cerro Leon and Joaquin silver-gold districts in Argentina's Santa Cruz province, with a combined JORC mineral resource of roughly 330 million ounces of silver equivalent (76.3 Mt at 135 g/t AgEq; Joaquin alone stands at 167 million ounces AgEq as of March 2026, and Joaquin was acquired from Pan American Silver in 2024). The company has moved into Pre-Feasibility Study workstreams, including geotechnical, hydrological and environmental baseline drilling. Its maiden integrated PFS for Joaquin and Cerro Leon was POSTPONED on 18 August 2026 from September 2026 to January 2027, to incorporate an updated Mineral Resource Estimate, additional infill drilling aimed at converting Inferred resources to Indicated, expanded metallurgical and process-design testwork, and heap-leach column trials for low-grade ore; the company frames the delay as delivering a higher-confidence study while still targeting inclusion in Argentina's RIGI regime in the second half of 2027. No completed PFS exists yet, so the stage remains resource definition.
Lifecycle Milestones
Not in place: mill, tailings facility. Not yet determined: road access, grid power.
Jurisdiction (40%)6/10
Santa Cruz, Argentina: Fraser PPI 2025 is 73.35 of 100 (rank 36 of 68), which maps to 9 on this site's scale, less 3 for Argentina's national currency, capital-control and export-duty risk, so 6. Argentina has historically carried elevated macroeconomic and currency risk, though Santa Cruz province is a well-established, mining-friendly district home to major operating mines such as Cerro Vanguardia.
Infrastructure (40%)2.9/10
No confirmed mill and no confirmed tailings facility at Cerro Leon & Joaquin Districts, Santa Cruz, Argentina; road access and grid power not yet researched, counted at a neutral 5/10 until established.

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.

Insiders, Investors & Smart Money
Notable shareholders and insiders whose involvement is worth knowing about, plus what we're seeing from institutional/large-investor activity.
One genuine sector specialist shows up on the register -- Commodity Capital AG, a German boutique that runs a dedicated global mining fund -- but at about 3.2% it is a small position rather than a conviction stake. The rest of the top holders are an Argentine investment company at 4.7%, a US small-cap value fund at 3.0%, and two individuals. No producer holds shares, institutional ownership is only 10.4%, and there are no insider transactions on record. This is a checked-and-little-found result, not a judgment about the company.
