Production Start...
The Bonanza Mine property includes the Harquahala and Golden Eagle mines, located approximately eight miles south of Salome, Arizona. The project totals 2,656 acres and has significant underground workings, from which some 180,000-200,000 ounces of gold were reportedly produced from high-grade ore in the late 1800's and early 1900’s. Mined rock and tailings from previous operations represent an additional potential resource.

Phase Two, currently under consideration, includes a much bigger package where potentially identified 150,000 – 300,000 oz of Au in defined underground targets in and around the old Harquahala mine with significant upside potential.

Summary:

The mineralization in the Harquahala district is varied and complex. Gold, silver, copper, lead, and zinc occur in pockety deposits, large and small, usually associated with iron oxides and gypsum where oxidized, and with auriferous pyrite in depth. Often the deposits occur in brecciated, lenticular quartz and jasper veins along shear zones and faults. The host rocks may be any of the Precambrian, Paleozoic, or Mesozoic rocks. Closely associated are diabase and aplite or quartz dikes and the source of the mineralization is believed to be the granitic intrusive. Spotty tungsten mineralization is associated with some discontinuous quartz veins and lenses in gneiss and limestone in scattered localities. Seams and irregular replacement bodies of mixed manganese and iron oxides occur locally in the metamorphosed sediments. The most prominent ore deposits, at the Bonanaza (Harquahala) and Gold Eagle mines, occur in strongly deformed and faulted metamorphosed Paleozoic sediments intruded by an elongated body of quartz monzonite. The rich, high-grade, but pockety shoots of gold ore in the oxidized zone give way to auriferous pyrite with some base metal sulfides in fracture zones in depth. The weathering and erosion of these deposits created gold placers in the gulches of the Little Harquahala Mountains close to the deposits. Titaniferous magnetite sands have been explored on the western peneplain of the Little Harquahala Mountains (T.4 N., R. 14 W.) but have not been exploited (Harre ........
