CAPSTONE MINING SA DE CV
CAPSTONE MINING SA DE CV is registered as a public limited company (sociedad anónima) with Mexico’s Registro Público de Comercio, filed through the SIGER 2.0 system operated by the Secretaría de Economía, under registration number CMI0604038I8. Its registered address is in the city of Zacatecas, Zacatecas state, and the registry records the company’s status as active; an active registration does not by itself confirm that CAPSTONE MINING SA DE CV is currently trading.
The website recorded for CAPSTONE MINING SA DE CV, capstonemining.com, redirects to capstonecopper.com, the official website of Capstone Copper Corp. (TSX: CS), a Vancouver, British Columbia-headquartered copper producer. This confirms an association between CAPSTONE MINING SA DE CV and the Capstone corporate family, though publicly available sources do not specify the company’s precise function within that group. Capstone Copper Corp. was created on 11 March 2022, when Capstone Mining Corp. completed its combination with Mantos Copper (Bermuda) Limited and adopted the Capstone Copper name, with the combined company’s shares trading on the Toronto Stock Exchange under the ticker CS.
Capstone Copper’s only Mexican asset is the Cozamin underground copper-silver-zinc-lead mine, located approximately 3.6 kilometres from Zacatecas City, within the same mining district as CAPSTONE MINING SA DE CV’s registered address. Cozamin has been in continuous commercial production since August 2006, and public company sources identify a separately registered Mexican entity, Capstone Gold, S.A. de C.V., as the subsidiary holding the Cozamin mining concessions. Available sources reviewed do not identify CAPSTONE MINING SA DE CV itself as a concession holder for Cozamin.

Group Structure
CAPSTONE MINING SA DE CV’s registry entry on file shows no parent, subsidiary or ownership linkage, consistent with the limited corporate-linkage disclosure typical of Mexican SA de CV filings, which do not publish a searchable ownership register. Independent research found one relevant indicator: the website recorded for CAPSTONE MINING SA DE CV, capstonemining.com, redirects to capstonecopper.com, the official website of Capstone Copper Corp. (TSX: CS). This confirms an affiliation with the Capstone corporate family but does not, on its own, establish CAPSTONE MINING SA DE CV’s specific place within that group’s ownership chain, so no immediate or ultimate parent is stated as verified below.
Capstone Copper Corp. is the company formerly named Capstone Mining Corp., which adopted its current name on 11 March 2022 upon completing its combination with Mantos Copper (Bermuda) Limited. Capstone Copper’s sole Mexican mining asset, the Cozamin mine near Zacatecas City, is held through a separately registered Mexican subsidiary, Capstone Gold, S.A. de C.V. — a distinct legal entity from CAPSTONE MINING SA DE CV, evidenced by a different registration number and incorporation date recorded in Mexican company sources. No filed document was located confirming a direct corporate relationship (such as a common parent) between CAPSTONE MINING SA DE CV and Capstone Gold, S.A. de C.V., so no sister-company relationship is presented as verified.

Recent structural changes: Capstone Mining Corp., the company whose name CAPSTONE MINING SA DE CV shares, completed its business combination with Mantos Copper (Bermuda) Limited on 11 March 2022 and was renamed Capstone Copper Corp.; this rename relates to the Canadian parent-level entity rather than to a confirmed direct change affecting CAPSTONE MINING SA DE CV itself.
Data availability: corporate-linkage information for CAPSTONE MINING SA DE CV is best described as not public. Mexican SA de CV ownership and group-structure filings are not accessible through a free public registry, and the only relationship evidence located — a website-domain redirect — supports an affiliate-level classification rather than a verified parent or subsidiary link.
