... rocks in the district, and includes intrusions and flow domes of dacite to rhyolite at Corimayo (10.8 Ma), Cerro Yanacocha (9.9 Ma), and Yanacocha Lake (8.4 Ma). Most of the gold (>47 Moz) was deposited at Yanacocha during intrusion of the late Coriwachay Dacite. These late dacites are volumetrically...

... With premining reserves plus resources of 10.2 million oz (Moz) of gold, 424 million metric tons (Mt) at 0.75 g/t, La Quinua is one of several world-class gold deposits that comprise the Yanacocha mining district in the Cajamarca province, northern Peru. Unlike volcanic-hosted high-sulfidation gold deposits...
