Metalero Mining Corp.
Metalero Mining Corp. (TSXV: MLO; formerly Cortus Metals Inc.) is an Edmonton-based explorer whose flagship is the San Cristobal East and San Cristobal South silver projects in the Potosi Department of south-west Bolivia. In May 2026 it applied for three mineral concessions covering about 230 km2 along the Uyuni Fault System: two, forming San Cristobal East, adjoin the San Cristobal silver-lead-zinc mine, and the third, forming San Cristobal South, adjoins the Isidorito silver prospect. Metalero has completed staking and surface sampling there and plans geophysics ahead of the first drilling, with exploration starting in the fourth quarter of 2026. Its second project is Benson, a 173 km2 copper-gold property about 15 km east of Quesnel in British Columbia's Quesnel Trough, held under an option to obtain 100%; AI-assisted targeting by Geoscience BC outlined five targets, and 2026 soil and geophysics work reported copper-gold anomalies at the Cantin and Sundberg targets. Neither project has a resource estimate.

Lifecycle Milestones
Jurisdiction (40%)4/10
The flagship San Cristobal projects are in south-west Bolivia, historically a resource-nationalist jurisdiction with weak security of mining title, although the government elected in November 2025 has signalled a more investment-friendly policy. Metalero's Bolivian concessions are applications that have not yet been reported as granted. The second project, Benson, is in British Columbia, Canada, a Tier-1 jurisdiction. Scored on the flagship's jurisdiction.
Infrastructure (40%)No verified figure
Researched with nothing found: no source we could cite confirms or rules out an existing mill, road access, grid power, or tailings facility at San Cristobal East and San Cristobal South Silver Projects, Potosi Department, Bolivia (checked Oct 5, 2026; recheck due Apr 3, 2027). Counts at a neutral 5/10 until one does.
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:1/10
Stage: Grassroots Exploration
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.
Management and insiders hold roughly 40% of the company, and two private placements closed in 2026 (one oversubscribed), but no named institutional, strategic, or specialist resource-fund investor could be identified on the company's own disclosures. A 1 means the register was checked and nothing beyond insider alignment was found, not that anything is wrong with the company.
