Griffon is located at the southern end of the Battle Mountain - Eureka Trend and is a typical Carlin-type sediment-hosted gold property. Disseminated gold mineralization occurs in siltstone and shale of the Mississippian Chainman Formation and in a sequence of fine-grained limestone and siltstone interpreted to represent an upper member of the Mississippian Joana Limestone.
The Griffon property lies 12 miles south of the White Pine Mining District and 12 miles north of the Currant Mining District. Exploration drilling in the late 1980s throughearly 1990s by Billiton Minerals and Westmont Minerals defined a small historic gold resource.
The property was acquired by Alta Gold Company in 1993. Drilling by Alta in the early- to mid-1990s resulted in the expansion of one historic deposit and discovery of another. Between 1997 and 1999, Alta Gold mined approximately 90,000 ounces of gold from the property before declaring bankruptcy in 1999.
Past exploration on the Griffon property focused on discovery and delineation of the two distinct historic gold deposits. Very little exploration work was done on peripheral targets after the initial discoveries.
Pilot Gold’s work on the property will be focused on geological mapping, geochemical and geophysical surveys to define targets proximal to the historic pits as well as new exploration targets property wide.
