A former underground gold mine in mica schist. Located on the Isle of Pines, 33 miles SW of Cuba proper. The mine is located ca. 45 km North-west of the islands capital Nueva Gerona.
The mine was only operated sporadically pre 1947. From 1947 to 1950 and then abandoned in 1958.
Various surveys and a new shaft was sunk in 1980 and closed around 1997.
Note on the mineral list: silver sulphosalts are present too (Nelson et al., 2011).
