Boroo Gold Mine

 mine, gold mine

The Boroo deposit was discovered in 1910. Industrial mining began shortly thereafter but ended in the 1920s when the facilities were destroyed in a civil war. Mining resumed in 1933 and a refinery was installed in 1942 that treated gold from the mining of a number of near-surface quartz veins. There are no production records from this time and events in the ensuing years until the mid-1960s remain undocumented.

Located 110 kilometers west-northwest of Ulaanbaatar, the country's capital, Boroo began commercial production on March 1, 2004 and produced more than 245,000 ounces of gold (including gold produced during commissioning) in that year. In 2011 gold production was 59,224 ounces as mining ceased at the end of November 2010. The Boroo operation continues to mill lower grade stockpiled ore while the company waits for the final approvals for the Gatsuurt project.

From March 2004 through to December 2011, the Boroo mine has produced approximately 1.5 million ounces of gold.

The Boroo gold deposit is generally flat lying or sub-horizontal and extends over an area measuring 2.5 by 1.5 kilometres. Throughout the area, a series of mineralized zones occur up to 400 metres wide and typically average from 10 to 30 metres in thickness.
