The major exploration (Preliminary and detailed) information was gathered from 1974 to 1982 by Balkhash GEP Co. Moreover, exploration continued in 2012 through digging of exploratory trenches and core drilling up to 40m.
Modelling and estimation of the Borley Copper deposit was performed based on exploration data. Mineral resource estimation of Borley is about 140 million ton and average grade of Cu is 0.35%.
