Name(s) in local language(s):
Mina Teresita (Mina del Aramo)
Epigenetic, carbonate-hosted Cu/Co/Ni deposit.
Host-rocks: Black fetid Namurian bituminous limestones (700 meters thick).
Complex mineralization with three successive primary stages and an important later supergene stage:
1) Pyrite-marcasite-bravoite: Co/Ni sulfarsenides and arsenides in dolomite; associated with acanthite. Cobaltite, safflorite, gersdorffite.
2) Intermediate stage: Tennantite and sphalerite in quartz/dolomite.
Renierite. Chalcopyrite (with briartite inclusions) and talnakhite replacing early assemblage. Tennantite and sphalerite replace cobaltite and safflorite.
3) Cu/Fe sulphides: Chalcopyrite, talnakhite, and bornite. Chalcocite, djurleite, digenite, covellite.
4) Oxidation sequence: Cementation copper sulfides, native elements, and oxidation minerals.
Production and reserves: 200,000 tons extracted.
400,000 tons ore reserves @ 1-3% Ni and 1-3% Co, 1-20% Cu.
