Gold Mines Bald Mountain ( History, Mining Methods And Operation )

     

      The Bald Mountain mine is one of largest gold mines in the world. The Bald Mountain mine lies within the Southern Ruby Mountains of northeastern Nevada, approximately 110 kilometers northwest of Ely, Nevada and 110 kilometers southeast of Elko, Nevada. Bald Mountain is operated by Barrick and ore is sourced from multiple open pits over an estimated 600 km2 property with processing at multiple conventional heap leaching facilities. Bald Mountain is the largest mine site by area in the U.S. It stretches 40 km north to south and 16 km east to west with the north and south areas being 19 km apart.

History Bald Mountain mine 

      The Bald Mountain mine lies on the western flanks of Little Bald Mountain and Big Bald Mountain. Rocks exposed in the area comprise a conformable, generally SSE dipping sequence of Cambrian to Silurian limestones, dolomites, shales, quartzites and siltstones. These sediments have been intruded by the Jurassic (159 Ma) Bald Mountain quartz-monzonite stock, and related felsic dykes, along a major north-west structural trend. Intense pre- and post-mineral faulting has produced a complex structural regime at Bald Mountain, controlled by the intersection of deep crustal NW and NNE trending fractures which have localised and controlled the location of gold deposits. Overall , the pluton, associated dykes and Au mineralisation are all controlled by the crustal scale, NW trending Bida Trend structure. Every rock exposed in that part of the district, from the lower Cambrian Hamburg Dolomite to the Silurian Laketown Dolomite has hosted some ore (Placer Dome, 1995).
