Summary:
Marlin has been in production since late 2005, operating as both an open pit and underground mine. Open pit operations ceased in early 2012 as the final, higher-grade portion of the open pit was mined, and the mine is now an underground operation only.
Underground operations employ mechanized cut-and-fill and long hole stoping mining, with underground loading equipment feeding haul trucks that transport the ore to the surface via ramps. Production from underground operations is now roughly 3,200 ore tonnes per day.
