Reference information

Comments Porphyry copper-gold deposit with associated replacement deposits (skarns, mantos) and high-sulphidation epithermal massive-enargite (gold) sulphide deposits. The deposit was mined to 1962 for massive pyrite and limonite, but since then the large porphyry copper deposit was mined by open pit with an annual production of 12–14 Mt (Jelenkovi? and others, 2007). Reserves at Majdanpek are estimated at 800 Mt of ore, containing 0.4–0.8 % Cu, and 0.25–1.0 g/t Au (Jelenkovi? and others, 2007). In concentrate: 7.8 g/t Au, 0.03 g/t Pt, 0.27 g/t Pd. Exposed. Location is for center of pit lake on Google Earth image. The main mineralization stage at Majdanpek occurred at 83.6–84.0 ±0.6 Ma, coinciding with the later stages of the first cycle of high-potassium calc-alkaline andesitic volcanism in the district (Clark and Ullric, 2004). Drew (2005) shows the Majdanpek porphyry copper deposit occurs in Late Cretaceous andesite as part of a positive flower structure within the northern extension of a north-trending strike-slip fault duplex.
