The geology and gold-silver mineralization of the Wilco Project—Willard Mining District, Pershing County, Nevada

TheWilco project area is located in theWillard Mining District, approximately 160
kilometers (100 miles) northeast of Reno,Nevada, and contains theWillard andColado
gold and silver resources representing epithermal, low-sulfidation-type (quartz ± calcite
± adularia) deposits. Mineralization is controlled by favorable lithology and structure.
TheWilco property area has a long history of exploration, development and production
dating back to the early 1900’s. TheWillard mines produced free-milling gold
from surface exposures, and in the 1990’s, Western States recovered gold and silver
from heap-leach operations. Rye Patch Gold optioned the Wilco Project from
Newmont Mining Company in 2006 and based on recent exploration drilling completed
a new resource estimate for theWilco project containing 788,000 ounces of gold
and gold equivalent in the measured and indicated category and 1,980,000 ounces of
gold and gold equivalent in the inferred category.
