Since 1965, the Carlin Trend has produced more than 50 million ounces of gold.

The geology, structure, alteration and mineralization encountered in drilling at REN are typical of Carlin-type gold deposits. The host rocks for gold mineralization include dolomitic to calcareous carbonaceous siltstones, mudstones and silty limestone underlain by a pre-mineralization silicified collapse breccia. Most of the host rock units are within the Popovich Formation of Middle Devonian age.

Since 1965, the Carlin Trend has produced over 50 million ounces of gold from an area 56 kilometres long and eight kilometres wide. Total production and reserves are close to 100 million ounces. Deposits along the Carlin Trend have gold concentrations that range from 0.7 to 34.0 grams per tonne.
