of the quartz veins. Two main ore types mined from this deposit are gold bear ing quartz veins, and gold sul fide disseminations in the meta sediments and metavolcanics in the neighborhood of the shear zones. A granite body to the SW of the concession is also mined for gold in a surface pit, where gold and sulfide minerals are

A wet chemical process was developed for the separation of gold from gold bearing antimony sulphide ores. The ore sample was taken from the mine Urquidi from Oruro in Bolivia. It contained roughly 33% Sb in the form of antimonite. 24% Si in the form of quartz, small quantities of Pb, Fe, Cu, and Ni as well as 63 g/t gold, 60% of it as visible gold.
