Griffin Mining Limited (“Griffin” or “the Company”) is a mining and investment company, incorporated in Bermuda in 1988, whose shares are quoted on the Alternative Investment Market of the London Stock Exchange (“AIM”), having been admitted to trading on AIM in 1997 as European Mining Finance Limited.

The major asset of the Company is an 88.8% interest in Hebei Hua Ao Mining Industry Company Limited (“Hebei Hua Ao”) (through its wholly-owned Hong Kong subsidiary, China Zinc Limited (“China Zinc”)), which holds licences, including the mine and processing facilities near Caijiaying Village (the “Caijiaying Mine”) in the People’s Republic of China (“PRC” or “China”).

Griffin has held an interest in Hebei Hua Ao since 1997 having financed and managed the development of the Caijiaying Mine from initial exploration to the extraction and processing of the equivalent of 1.5 million tonnes of ore per annum to produce primarily zinc but also gold, silver, and lead in concentrate.

Griffin has invested over $380m on acquiring its interest in Caijiaying and in the development and construction of the mine and processing facilities, financed mainly from internally generated funds. The Caijiaying Mine was commissioned on time and on budget in 2005.

Numerous upgrades to the Caijiaying Mine have taken place since commissioning leading to the current name plate mill throughput capacity of 1.5 million tonnes of ore per annum.
