Operations

New discoveries & progress in community relations.

In 2010, Marlin mine produced its one-millionth ounce of gold and continues to generate significant cash flow. Marlin has been in production since late 2005, operating as both an open pit and underground mine. Open pit operations will cease in 2012 as the final, higher-grade portion of the open pit is mined, and the mine will become an underground operation only. Successful exploration activities in the area indicate the potential for extending the life of this highly productive mine.

The recent discovery of a new bonanza grade vein—the Delmy vein, which is located near the Marlin deposit and within the existing mining area—will contribute significantly to the mine’s future production. Underground development is in progress towards this vein.
