Summary of the Proposed Golden Sunlight Mines Amendment

Golden Sunlight Mines, Inc. is proposing to expand its current mining operation with the addition of one new pit called the North Area Pit, and an expansion to the existing Mineral Hill Pit known as the South Area Layback. The company anticipates mining approximately 4.2 million tons of gold ore, which will be processed at the existing mill facility, generating up to 52.6 million tons of waste rock. Mining would use conventional open pit methods including drilling, blasting, loading, and hauling. All proposed facilities are located on private land owned by Golden Sunlight.

The proposed North Area Pit would extend below the natural water table so dewatering would be necessary. During mining operations, water would be used in the milling process and would offset fresh water usage. After mining is completed, captured water would be pumped to a water treatment plant consistent with existing permit requirements. The proposed South Area Layback would be free draining into the Mineral Hill Pit so dewatering would not be necessary.

Waste rock generated from the proposed expansion would be placed in the proposed East Waste Rock Dump Complex Expansion Rock Disposal Area.

Proposed mining activity at the North Area Pit and South Area Layback would be completed in late 2016 or early 2017. The proposed amendment would extend the mine life by approximately 2 years and would provide for an additional 2 years of processing off-site ore, mostly derived from legacy mining materials located within southwest Montana.
