Gold Bar project is a proposed mine development project consisting of a conventional open pit mine with an oxide gold heap leach recovery circuit. The project is located within the Battle Mountain-Eureka-Cortez gold trend in Eureka County, Central Nevada. The property was previously mined from 1990 to 1994 by Atlas Precious Metals Inc. The nearest operating mines are Barrick Gold's Ruby Hill, which produced 127,000 ounces of gold in 2011 and is located approximately 25 miles to the Southeast; and Barrick Gold’s Cortez mine, which produced 1.42 million ounces of gold in 2011 and is located approximately 35 miles to the Northwest.

The Gold Bar project is currently in the permitting phase with construction expected to begin in 2014, and gold production expected in 2015. A pre-feasibility study was completed by SRK Consulting and published in November 2011.
