In recent years, the geological service of Kazakhstan has been assigned the task of searching for sites where ores would meet modern industrial requirements. It has become a matter of re-evaluation of lead-zinc deposits and of identification among them of promising non-traditional commercially genetic types. One of these is the karst type, which has the following features: high lead and zinc content, compact ore deposits, effective ore enrichment, wide development in Kazakhstan of carbonate rocks with lead-zinc mi...

In the world practice, lead-zinc karst deposits occupy one of the leading positions in terms of reserves and rich ore mining. In terms of metal content, they excel all other commercial-genetic types. Karst deposits are a new commercial-genetic type for Kazakhstan. One of the promising regions for discovery of the karst deposits is the Great Karatau, known for such objects (Achisai, Karasai, Kantegi, Araltau and oth.). The area of the Achisai ore cluster is composed of thick carbonate strata of limestones and dolom...
