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.
