TWIN CREEKS UNDERGROUND

Twin Creeks Underground – Twin Creeks First Underground Project

SMD started an exploration drift (originally known as Vista) at Twin Creeks in 2011. After a short period of underground drilling, we continued exploration drifting in 2012 and 2013. We completed some test stoping in 2016 and Newmont reached a production decision in 2017. We mobilized in July 2017 to advance development and begin production mining.

Total development drifting at the end of 2018 is 37,000 feet and we have mined about 300,000 tons of ore and 250,000 tons of backfill – both CRF and gob. The Twin Creeks Complex is now part of Nevada Gold Mines Joint Venture.
