The Malmyzh Cu-Au Porphyry deposit is located in Khabarovsk Krai of the Western Sokhote-Alin metallogenic Province in Far East Russia.
The deposit was officially listed on the Russian State Balance in May, 2015 with the initial reserve (C1 + C2) of 1.4 Billion Tonnes ore grading 0.52% copper equivalent containing 7,228,000 Tonnes copper equivalent metal and a P1 resource of 0.93 Billion Tonnes ore grading 0.44% copper equivalent. Total initial Russian reserves and P1 resources (C1 + C2 + P1) at Malmyzh currently stands at 2.32 Billion Tonnes ore grading 0.49% copper equivalent containing 11,368,000 Tonnes of copper equivalent metal. Also in 2015, a 43-101 “in-pit” Resource was completed by Wardell-Armstrong providing 1.66 billion tones of ore grading 0.42% copper equivalent containing 5.65 million tones copper and 9.1 million ounces of gold.
Malmyzh represents a grass-roots discovery resulting from several years of prospecting phase exploration works completed by OOO Amur Minerals, a joint venture private stock company controlled by Freeport McMoRan Corporation and IG Copper LLC.
Malmyzh is important not only due to the obvious economic benefit of the deposit, but also due to its future implications to the Russian mining and exploration industry by opening the Sokhote-Alin Metallogenic Province as a new regional scale prospective belt for porphyry copper-gold deposits.
