PERTH, Western Australia, Nov. 2 /CNW/ - The Directors of Sierra Mining Limited (Sierra) are pleased to advise that the Company has entered into an Exploration Alliance with CGA Mining Limited (CGA) (TSX: CGA), which allows Sierra to accelerate its exploration programs on its outstanding projects in the Philippines, as well as pursue new opportunities.

CGA - who has developed the Masbate Gold Project in the Philippines, the largest gold mine in the country - will provide Sierra with strategic, commercial and technical assistance in respect of its projects, and the companies will work together to identify and secure other exploration and development opportunities in the Philippines.

Matt Syme, Managing Director of Sierra, said "Sierra is delighted to be able to strengthen our relationship with CGA through this Alliance. CGA is one of the great success stories in Philippines mining and their support on the ground will be an immense help in progressing our excellent property base."

Michael Carrick, Managing Director of CGA, commented "CGA has great faith in the future of the mining sector in the Philippines and the contribution it can make to the Philippines economy. Sierra has an outstanding portfolio of projects and this Alliance is a terrific opportunity for CGA to participate in the great untapped exploration potential in the country."
