Chairman's Statement

Griffin's Chairman, Mladen Ninkov, commented: "The recent announcements by Griffin in relation to its record 2011 financial results, record production, 32% increase in its JORC mineral resources, further exceptional exploration results and the continued movement to greater production at Caijiaying, fully justifies the decision to acquire a greater interest, and extend the term of, Griffin's interest in the Caijiaying Mine and surrounding areas. As Griffin now progresses towards increasing production at Caijiaying, and with the hope of continuing favourable metals prices, the returns to Griffin and its shareholders should not only justify the price paid by the Company in this transaction, but exceed all expectations. We look forward to making this so."
