entire area of East Balkhash-1 (250 km to the north-east from Balkhash
town) is conditionally divided into two parts, some areas mainly with
copper-porphyry mineralization ("Karaozek", "Bekbosyn", "Tassu")
projects and areas with gold mineralization ("Zhorga" project).
Many aspects, including environmental and social ones, that can affect
the success of the project were investigated. A strategy and a specific
list of necessary actions and activities had been defined.
For projects of "Karaozek", "Tassu" and "Bekbosyn", the discovery of a large or even unique copper deposit is expected.
Under the "Zhorga" project, a search is being made to finance the
construction and start-up of the ore processing complex for the
processing of gold-bearing ores at the sites of Zhorga IV and Sholadyr.
Proved ore reserves in these areas amount to 2,518,000.0 tons
containing 5,053.0 kg. of gold, with an average content of 2.01 g / t.,
which is sufficient for a cost-effective working period of more than 6-7
There are also estimated resources of sites,
1,236,000.0 tons of ore, containing 2 465.0 kg. of gold, with an average
content of 1.99 g / t.
Comprehensive work was carried out to study ore for ore dressability, an analysis of available technologies was carried out.
It is planned to build a factory for ore processing by flotation
technology, with gravitational processing of tailings of flotation, and,
subsequently, cyanidation of the obtained collective concentrate using
CIP technology. The technological process of enrichment and production
chosen by the company differs relative simplicity and reliability, which
explains its wide application.
Near surface occurrence of ore
bodies, as well as favorable hydrogeological conditions and high
geotechnical properties of the constituent ore and overburden,
determined the design solution for open-pit mining.
To date, slightly more than 6.0 million US $ has been invested.
