Musselwhite is a low-grade under - ground operation in a remot e corner of Northern Ontario, 430 km north of Thunder Bay . Since achieving its frst commercial production in April of 1997, Mussel - white has produced over three million ounces of gold. The 2010 discovery of the L ynx Zone-a zone of higher - grade ore above the cornerstone PQ Deeps under ground operation-has created the potential to signifcantly enhance economics and extend pro - ductive mine life. Exploration continues to test other high-potential lateral tar gets and ex - tension of existing gold structures. The workforce is 855, including contractors, and the mine has an es - timated life of 13 more years. The 2013 production run through a 4,500 tonnes per day mill is estimated be - tween 250,000 and 260,000 ounces. Gold production for 2012 was 239,200 ounces as against 242,600 in 201 1. Goldcorp says at Musselwhite gold production is ex - pected to increase slightly as min - ing continues to progress in the PQ Deeps and L ynx zones. Exploration will continue to fo - cus on the northern extension of the L ynx Zone from surface and under - ground, drilling of the W est Limb and the under - ground extension of the PQ Deeps. Surface drilling from bar ges has returned encour - aging results on the L ynx Zone and additional miner - alized shear zones have been inter - sected on the W est Limb. Musselwhite contained 2.29 million ounces of proven and probable gold reserves at Dec. 31, 2012, compared to 2.28 million ounces at Dec. 31, 201 1, due to exploration success in the L ynx and PQ Deeps and a higher gold price assumption. Increased re - serves were partially of fset by revi - sions to reserves in the PQ Deeps. Exploration drilling in 2012 contin - ued to focus on the extension of the L ynx Zone, both from the surface and under ground, with initial surface and under ground exploration of the W est Limb area. Under ground drilling ex - tended the L ynx Zone mineralization by 175 metres northwards and 50 me - tres southwards and defned a small intraformational unit in the hanging wall of the surface along the upper portion of the ore body . Surface and under ground drilling was completed for the frst full drill sec - tion on the W est Limb tar get, with the inte rsection of a number of shear zones and encouraging results. T wo prospectors, brothers Harold and Alan Musselwhite, found erratic gold mineralization in 1962 on the north side of Opapimiskan Lake. They con- tinued to explore the area until 1973 when several lar ge mining companies became involved. One of them was Placer Dome and it, along with part - ner TVX, deci ded to put the deposit into production. The mine opened in 1997 and over time several major ore zones were found on the lower limbs of the PQ Deeps synform adjacent to the origi - nal T -Antiform ore zones. Goldcorp became sole owner of the mine in 2007. The Musselwhite mine operates near the territory of four First Nation vil - lages: Cat Lake, Round Lake, W un - numin Lake and Kingfsher Lake. The closest of these villages is located about 50 km from the actual mining sites. Agreements guarantee jobs and train - ing for Aboriginals .
