Ore controlCarbonaceous Silty Limestone Of Roberts Mountains Formation Provided A Favorable Host For Gold Deposition. Northeast-Striking High Angle Normal Faults Served As Conduits For Mineralizing Fluids. The Majority Of Gold Was Deposited In An Imbricated Thrust Zone Below The Roberts Mountains Thrust Within The Roberts Mountains Formation. The Upper Skarn May Have Acted As A Caprock.

StructureReg.Struct: Gold Acres Is Exposed At The Western Margin Of The Gold Acres Window Along The Nw-Trending Roberts Mountains Thrust, Cortez-Uinta Axis. It Lies Along The Eureka-Battle Mountain Trend Of Aligned Intrusives And Mineralization., Common High Angle Normal Faulting At Numerous Orientations Has Broken The Mineralized Zone Into Three Parts: The Main Gold Acres Orebody, Little Squirt Orebody, And Little Gold Acres Orebody.
