Info

The emerald deposits around Muzo were originally worked by the Incas up to 2000 years ago and were “rediscovered” by the Spanish in 1559. There has been a long history <strong>of</strong> intermittent production from these mines continuing to the present day. 11
The mines have been owned by the government since 1871 and have been leased to various operators since then. Five year leases were instituted in 1977 and discontinued in 1982 due in part to poor recovery brought about by rapid mining techniques (dynamite and bulldozers). Ten year leases were most recently held by two companies Tecminas and Coesminas, who developed underground workings. 12
