Excellent progress has been made at South Mountain. Underground miners, Widman Contractors, Inc., of Baker City, Oregon mobilized late in 2012 and commenced site work on the upper Laxey and lower Sonneman Levels. Widman’s nine-man crew completed construction of the steel portal sets and commenced expanding the size of the drift for future production, with the main Sonneman Level being enlarged to 12 ft X 12 ft. The expanded size accommodates mining with diesel rubber tired equipment. As of mid April, mining had advanced 300 feet on the Laxey Level, and 400 feet in the Sonneman Level. Despite high initial costs associated with winter weather and infrastructure construction, the development costs have now stabilized at $800 to $900 per foot of drift.
