The Gold Ridge project lies within the Dos Cabezas Quadrangle. This region is interpreted to be a large, late Cretaceous-early to Tertiary-aged plutonic-volcanic centre constructed on deformed and intruded Precambrian, Paleozoic and Cretaceous-aged metavolcanic and metasedimentary rocks.
These rocks were subsequently cut by the Apache Pass Fault Zone, a regional vertical shear zone that is believed to control the location of the high-grade gold vein systems like that at Gold Ridge.
The Apache Pass Fault, traced along a west-northwesterly trend for more than 20-miles, is the dominant structural feature of the Gold Ridge project area. The fault is interpreted to have had a long history of recurrent movement and is believed to be an important control for the localization of the ore-bearing veins of the district. Numerous late north- to northwesterly-trending faults cross the main shear zone and offset mineralized veins from a few feet to several hundred feet.
On the property, Gold-bearing, irregular, quartz-sulfide veins occur within a sheared and faulted zone in Cretaceous-age sediments. The productive veins of the Gold Prince mine parallel the main shear zone and are localized along a complex set of related west-northwest, south dipping quartz veins and shears.
The high-grade gold-bearing vein system at the Gold Prince mine is part of a three-mile vein swarm that includes both barren and mineralized veins. West of the Gold Prince mine, the Gold Ridge mine appears to have been offset approximately 400 feet to the north along an ill-defined cross-fault.
The mines on the Gold Ridge property are believed to be mesothermal in nature and similar exhibit similar features to the Low-Sulphide Gold-Quartz vein model that describes California’s mother-lode and Canadian Abitibi deposits.
Two separate metallurgical studies were performed on mineralization taken form the level 5 drift of the Gold Prince mine; one in 1988 by Bateman Metallurgical Laboratories (Nevada), and the other in 1996 by Hazen Research Inc., (Colorado).
Both Studies returned in excess of 97% gold recovery using standard gravity and floatation methods.
