Hong Kong, Sep 14, 2010 AEST (ABN Newswire) - CST Mining Group Limited (HKG:0985) is pleased to announce that Macrobre has received the approval from MEM for its EIA of the Mina Justa Project in Peru.

Reference is made to the circular of CST Mining Group (the "Company") dated 30th April, 2010 (the "Circular"), in respect of, inter alia, the Mina Justa Project. Terms used herein shall have the same meaning as those defined in the Circular unless otherwise specified.

APPROVAL OF EIA OF THE MINA JUSTA PROJECT

The Board is pleased to announce that the Ministry of Energy and Mines of Peru ("MEM") has, on 8th September, 2010, issued its approval to Macrobre, the 70% owned subsidiary of the Company, for the Environmental Impact Assessment("EIA") of the Mina Justa Project.

With the approval of the EIA, the Peruvian government has certified the environmental feasibility of the mining project, which comprises an open pit mine, mineral processing facilities, power transmission and water delivery infrastructure, and an access road.

The EIA approval is a key milestone in the construction and operation of the mining project, since it is a requirement for the approval of the construction and operation authorizations.

In conjunction with this approval, Macrobre will move the first phase of the project into detailed engineering and will look to start early construction works on the water line, access road and camp as soon as possible.
