- Intermediate-sulphidation epithermal Au-Ag
Late Cretaceous Apuseni-Banat-Timok-Srednogorie magmatic and metallogenic belt, Breznik palaeovolcano. Eight vein zones 400 to 1000 m long, a few centimetres to 3-4 m thick (rarely 10 to 15 m), down to 200 m depth, in altered trachybasalts and andesitic trachybasalts (propylitic, sericitic without adularia, argillic). Zone no. 8, with advanced argillic alteration (quartz, kaolinite, alunite, APS minerals) and copper (chalcocite, bornite, covellite), is linked to a high-sulphidation system and a probable porphyry at depth. Three stages: quartz-pyrite, quartz-polymetallic (pyrite, galena, Fe-poor sphalerite, tennantite, tellurides, electrum), carbonate-gold (native gold, stibnite, barite). Primary fluid inclusions in quartz: Th 238 to 345 °C, 3.7 to 6.6 wt% NaCl eq. Probable reserves and resources: 13.1 t gold and 59.5 t silver (2.4 Mt at 5.91 g/t Au). Coordinates from Mindat.
