Highlights:
· New Licences incorporate two historic operating (extremely high grade), copper-lead-zinc mines (Pokrovskoye and Talovskaya), one known deposit ( Verkhubinskoye), and many historical mineral occurrences
Talovskaya - A massive sulphide ore deposit found in 1782 and mined up to 1896, consisting of many ore lenses up to 30 m by 60 m with grades up to 11.9% Cu, 16% Zn and 2% Pb. The most recent exploration was conducted between 1989 and 1992, which found disseminated sphalerite.
The main rock type in the ore field is tuffaceous siltstone. Large volumes of malachite veinlets along a granite porphyry were reported from the first field visit (Figure 1) as well as magnesium skarns nearby. In the area are lots of smaller waste dumps and outcrops with malachite.
Pokrovskoye - Found in 1822 and mined up to 1979. The massive sulphide ore body was reported as 150 m long by 200 m wide and up to 22 m thick with average ore grades of 11.5% Cu, 3.3% Pb and 12% Zn.
This ore lens was located in a flexure along the contact of andesitic lava with a rhyolitic body. The volcanic formation was hornfelsed by granite prior to the ore stage. During this, there was tectonic brecciation with chlorite and sericite alteration.

A number of additional reports have been located and ordered from the state geological data provider which will provide more detail to the above-mentioned historical reports. Once received, key data will be digitised and analysed to continue to grow the Company's geological model and understanding of the region and specifically the areas of known mineralisation.
The final deliverables from the HEM survey have now been received and are currently undergoing processing by East Star's external consultants after which a thorough geological review will take place to assist the modelling and then ranking of priority targets.
The infrastructure on the licences includes rail, road and power and the area boasts two potentially suitable mills - both carrying spare capacity - making the economic threshold to develop any discovery extremely low as well as strategically important for the two regional producers being KAZ Minerals and Kazzinc (owned by Glencore and Tau-Ken Samruk). East Star is working with the same Kazakh service providers used by Kazzinc for its regional geophysics and the data, when combined with historic data which are still undergoing analysis, will be provided to global VMS experts for analysis to assist with drill targeting.
