⚠ COMPLIANCENot legal, tax, or investment advice — and not authorization for any transaction. U.S. sanctions (the Cuban Assets Control Regulations, 31 CFR Part 515) heavily restrict — and in most cases prohibit — dealings between U.S. persons and Cuba, including any form of investment or equity in a Cuban business. The rules are complex, fact-specific, and change; nothing on this site is a determination that any transaction is lawful. Structure anything Cuba-facing only with qualified OFAC sanctions counsel, and screen every party (names, entities, wallets) with QvaPay Sentinel.Primary sources: OFAC Cuba Sanctions · 31 CFR Part 515 (CACR) · OFAC Cuba FAQs · Cuba Restricted List

Matahambre Copper Mine

Historic underground copper mine (closed)

🔴 Stateℹ️ Atlas — info only
Scale
Worked 1913-1997; chalcopyrite veins/lenses in the Jurassic San Cayetano Formation
Status
Closed 1997 as depth-driven costs rose; declared a Monumento Nacional in 2000 and now a heritage site with a municipal museum. A restart means dewatering a deep abandoned mine — realistically a brownfield exploration target leveraging Emincar's infrastructure 7 km away, not a standalone reopening.
