The area is underlain by the Weaver Lake Member of the Lower-Middle Jurassic Harrison Lake Formation which consists of a series of basaltic to rhyolitic flows, flow breccias and bedded tuffs. Strong regional faulting has resulted in intense local fracturing and shearing. Structural features appear to have controlled the locus of hydrothermal alteration and associated mineralization. Alteration in the flows consists mainly of epidote with local concentrations of chlorite, zeolite and potassium alteration. Minor drag folding or warping was noted adjacent to the fault/shear zones.

Along the northern boundary of the claim are a series of basaltic to rhyolitic flows, flow breccias and tuffs. A distinctive intermediate flow breccia, composed predominantly of rounded feldspar porphyry fragments, forms a predominant bluff in the northwest part of the claim. Very fine grained lapilli tuffs underlie this breccia. Below the tuffs are massive basaltic to andesitic flows.

Two large zones of alteration and related mineralization were mapped. These zones lie along fault drainages and represent strong fracture zones associated with the faulting. The resultant alteration consists of local silicification, bleaching (clay alteration), quartz veining and the local occurrence of epidote, chlorite and sericite. The degree of alteration is relative to the proximity of, and the intensity of, the fracturing or shearing.

Sulphide mineralization is directly related to the alteration and varies from broad pyritization, between 1 to 10 per cent, to vuggy quartz veining with minor disseminations or aggregates of sphalerite, chalcopyrite and pyrite +/- galena. Quartz veining varies from white to grey, massive to vuggy and appears to crosscut the alteration. Minor barite is associated with the quartz. The veining is thin and sporadic although local stockworks were reported.

In 1985, seven rock samples were collected from the highly altered zones which have associated sphalerite, pyrite, barite and quartz in variable amounts. All samples were anomalous in barium and zinc with minor copper, cadmium, manganese and silver. One sample yielded 2.9 grams per tonne silver, 0.44 per cent copper, 1.72 per cent zinc, 0.16 per cent lead and 0.1 per cent barium (Assessment Report 14221).

In late 2002, the area was staked by Efrem Specogna. In 2004, the claims were optioned by Carat Exploration Inc and through 2007, programs of geological mapping, rock and stream sediment sampling and 347.2 line-kilometres of airborne geophysical surveys.
