The Eagle Nest Mining Property
The Eagle Nest claims include a previously producing Au-Cu-Ag-Fe (Gold, Copper, Silver and Iron) mine located 10 miles off Highway 95 in La Paz County, Arizona. Easy access to the mine site and a good water supply will facilitate ease of construction for a potential processing plant as well as expansion of the mine site.
Mineralization previously documented on Eagle Nest is very fine-grained to visible flaky gold, with oxidized copper ores and staining, in a linear, lenticular ore body with a steeply dipping fault zone cutting metamorphic Mesozoic, red, hematitic shale. Lenticular ore body formed from oxidation and enrichment was also found in the fault zone.
Previous workings include a 400 feet (121.92 meter) deep shaft and about 170 feet of drifts on the 100 level with some near-surface stopes. The previous mining operation on this property recorded historic productions of 1,050 tons of ore averaging about 1.07 ounces per ton gold, 1.8% copper and
2.1 ounces per ton silver.
History of the Bouse Mining District
The Bouse Mining District, where Eagle Nest is located, is a mid-tertiary system of epithermal mineralization, which was introduced into a stacked sequence of lithotectonic units that are located on the northern side of the Plomosa Detachment Fault. Complex epithermal gold, barite and fluorite mineralization is superimposed on earlier copper- specularite mineralization. Gold occurs in laterally extensive breccias and in steeply dipping amethystine-quartz veins. These deposits are similar to the proven and mined Copperstone and Mesquite deposits.
This District involves an important type of Arizona gold deposit, called a "detachment fault" deposit. Detachment fault deposits were first recognized as a separate form of gold deposit in the 1980's. The best example of an Arizona detachment gold deposit is Copperstone, which is about 20 miles from Bouse. It was the biggest gold discovery in Arizona in at least 50 years. Cyprus Gold profitably mined the 500,000 oz open pit resource during the 1980's. The Bouse Mining District is an historic gold producer.
