Properties

Hoover Hill is located five kilometers east of Revolution’s Jones-Keystone property.  Recently announced drilling at Jones-Keystone includes: Hole JK10-06 28.0 meters averaging 3.01 g/t Au within an interval of 54.0 meters averaging 1.56 g/t Au (see news release issued January 11th, 2011).  The geology at Hoover Hill is compared in the historic literature to Jones-Keystone with mineralization hosted in a volcanic series with pyrite as the main sulphide. Like Hoover Hill, gold and sulphides are concentrated in brecciated zones. 

Seven mineralized zones were previously mined at Hoover Hill. The discovery of gold mineralization dates back to 1848, and was subject to small scale mining until 1881, when Hoover Hill Gold Mining Co. erected a 20-stamp mill and worked it until 1885. The mine resumed production again from 1914-1917, and was allowed to flood in 1922 after shafts were constructed down to over 100 meters below surface.  Historic production totals are not well documented, however at least three large four by three meter shafts are exposed on surface, and multiple open stopes are now caving in at surface.

Earnhardt South-Sawyer

Located along the southern and eastern margins of Romarco’s Hickory property (formerly the Old Sawyer Mine), Earnhardt South-Sawyer exhibits strongly altered andesitic volcanic rocks and sediments.   The Old Sawyer mine has a similar history to Hoover Hill. Initial operations at Sawyer began prior to 1850, with the height of mining peaking in 1906 when a 50 meter shaft was sunk, in addition to six smaller shafts.
