Geological, geophysical, and mineral resource data relevant to sandstone-hosted copper deposits in central Kazakhstan

Central Kazakhstan is host to one of the world's giant sandstone-hosted copper deposits, the Dzhezkazgan deposit, and several similar, smaller deposits (Gablina, 1981; Susura and others, 1986; Cox and others, 2003; Hitzman and others, 2005). As part of it

Porphyry copper assessment of northeast Asia: Far East Russia and northeasternmost China

This study delineated permissive areas for undiscovered porphyry copper deposits, compiled a database of known deposits and significant prospects, estimated undiscovered deposits within those areas and made probabilistic estimates of their metal content.
