Capstone Copper CorpC
Capstone Copper Corp (TSX: CS / ASX CDI: CSC) is a Vancouver-headquartered, multi-jurisdiction copper producer formed by the 2023 merger of Capstone Mining Corp and Mantos Copper. Mantoverde (Atacama Region, Chile; Capstone 70% / Mitsubishi Materials Corporation 30%) is the flagship and largest-production asset: originally an oxide/SX-EW copper-cathode operation producing electrolytic copper since 1995, transformed by the ~$870M Mantoverde Development Project (first sulphide copper concentrate Jun 2024, commercial production Sep 2024, full milling rates by end of 2024) into a combined oxide-and-sulphide operation; annual copper production reached 95,115 tonnes in 2025, a 65% increase over 2024. A further, smaller ~$176M 'Mantoverde Optimized' brownfield expansion was sanctioned in Q3 2025 (currently in construction) and is covered by a Nov 2024 NI 43-101 Feasibility Study showing an after-tax NPV8% of $2.9B (100%-basis, $4.10/lb long-term copper price) and a 25-year mine life (extended from 19 years), with throughput rising from 32,000 to 45,000 tonnes/day. Mantos Blancos (Chile, 100%) and Cozamin (Mexico, 100%) are the company's other two active producing mines; Pinto Valley (Arizona, USA, 100%) is the original legacy Capstone Mining asset. Growth pipeline includes Santo Domingo (Chile, an up-to-25%-interest JV with Orion Resource Partners) and San Antonio, both pre-construction.

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.
Jurisdiction (40%)7/10
HQ Vancouver, Canada, TSX/ASX CDI dual-listed. Operating assets sit entirely outside Canada: Mantoverde and Mantos Blancos (Chile, Tier-1/2, established large-scale copper-mining jurisdiction), Cozamin (Mexico, Zacatecas state -- generally stable historically but carries real Mexico-wide operational/security risk distinct from Chile or the US), and Pinto Valley (Arizona, USA, Tier-1).
Infrastructure (40%)10/10
A confirmed mill, confirmed road access, confirmed grid power, and a confirmed tailings facility at Mantoverde Mine.
Nearby producing mine (20%)Not yet researched
No producing mine within 50 km in our reference list (nearest listed: El Salvador (Corporacion Nacional del Cobre de Chile), 83 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.

No pending acquisition or merger disclosed (checked)
Not scored: having no deal in flight isn't held against a company.

Not scored: most juniors that do get bought had no prior toehold, so a missing stake says little either way.
