The Mineral Ridge gold property has produced over 626,000 ounces of gold from two distinctly different types of deposits.  The most important is the mesothermal gold quartz veins and adjacent silicified zones that historically have been recognized at the only gold producing system on the property.  The mesothermal veins generally lie conformably at or above the granite contact with the lower Wyman formation.  The early miners exploited these high-grade veins by underground mining methods and more recently by open pit mining. 

The second most important gold producing system is the recently recognized epithermal quartz-sulfide veins, breccias and related mineralization that overprints the earlier mesothermal veins. The epithermal quartz-sulfide veins and breccias occupy late cross structures formed while the Mineral Ridge core complex was being uplifted from the ductile to the brittle environment.  These veins have not been previously recognized, but are distinct and have probably made significant contributions to the total gold inventory of the district. 

An analysis of the various favorable geological features associated with the two types of veins has been completed.  These include defining the different types of gold veins and when they formed, performing a structural reconstruction of the host rocks through time, and identifying the extent of the favorable geological environment that gold deposits could be found.  This work then allowed certain conclusions for discovering significant new gold mineralization in previously unrecognized targets.

The exploration potential was analyzed by identifying both mesothermal and epithermal targets.  The 5 targets that were identified have potential for the discovery of 3.0 to 4.7 million ounces of gold.  These targets are:
