Hercules Silver Property, Idaho

About the Hercules Silver Property 1,2,3,4,5

The 866-hectare Hercules Silver Property, on the northwestern shoulder of Cuddy Mountain and 200 kilometers northwest of Boise, Idaho , consists of 40 unpatented lode mining claims, one patented lode claim and an additional 475 hectares of private land with attendant access, exploration, mining, milling and water rights. Cuddy Mountain is an uplifted and tilted fault block of accreted Mesozoic terrane about 19 kilometres across, characterized by open grassy slopes. It is surrounded on all sides by rocks of the Columbia River Basalt Group. The core of the mountain is a Triassic-Jurassic sequence of volcanics, volcaniclastics and sediments.

The Cuddy Mountain conglomerate, the basal unit, is 61 metres to 122 metres thick. It grades upwards into fragmented andesite. The Jurassic ash-flow Hercules Rhyolite, which contains the silver mineralization identified historically, overlies the andesite unit. Maximum thickness of the rhyolite, ranges from 91 metres to 122 metres.

The rhyolite, where not exposed, lies below the Brownlee unit which is composed of andesitic pyroclastic tuffs, lenses of manganiferous limestone and lesser amounts of shale and sandstone.  Silver values in the 300 to 950 g/t range and generally associated with fractured, shattered and brecciated zones within the Hercules Rhyolite have been recorded in drilling and channel sampling. (See Table 1.) The Bald Eagle team believes that the mineralization is hydrothermal (epithermal). 1

Mineralization has been identified over 4,800 metres of exposed Hercules Rhyolite, with targets from south to north including the Belmont , Haystack Ridge, Fishpond, Hercules Adit, Hercules Ridge and Grade Creek zones. 1

Historical work completed between 1965 and 1988, included results from 307 drill holes and 320 metres of underground development.  Of the 307 drill holes, 28 were diamond drill holes, 43 underground percussion, and 236 reverse circulation. As a result of the drill campaigns two target types were identified, being high grade silver accompanied by 1-2 % lead and zinc and lower grade disseminated silver suggesting bulk tonnage potential.

Limited mineralogical work indicates that silver-bearing minerals are included in a polymetallic assemblage of sulfosalts including tetrahedrite-tennantite and polybasite with accessory pyrite, sphalerite and galena. 1,2,4,5

Mineralization occurs in brecciated pipe-like zones as well as broad, tabular zones, each being surrounded by halos of lower grade material. Historic drilling shows the pipes to increase in grade and thickness and remain open at depth. The two largest silver-in-soil anomalies on the Property occur at the Hercules Ridge which has seen little drilling, and the Grade Creek Zone which has not been drilled. 1,2
