The claims are underlain by Lower Jurassic Hazelton Group volcanics comprised of andesitic to rhyolitic flows, tuffs and breccia with minor intercalated sediments. South of the claims a Late Cretaceous to Eocene quartz-feldspar porphyry stock intrudes the volcanics with associated felsite dikes.
The Idaho workings at elevation 1623 metres, consists of a 2.5 metre hole in amygdaloidal andesite which hosts minor bornite and chalcopyrite. To the south, a quartz vein up to 30 centimetres in width strikes 055 degrees and dips steeply southeast. Mineralization consists of bornite over 2.5 to 10 centimetres width on the hanging- wall.
The Mohock adjoins the Idaho farther up the hill. The Mohock showing is a breccia zone striking 095 degrees in highly chloritized, green andesite. The reddish, brecciated dike rock hosts disseminated bornite and chalcopyrite across a width of 1.2 to 1.5 metres. In 1914, a sample taken across 1.0 metres assayed 2.7 grams per tonne gold, 706.3 grams per tonne silver and 5.4 per cent copper (Minister of Mines Annual Report 1914, page 219).
WORK HISTORY
In 2007, Lions Gate Energy Corp conducted an Aerotem airborne geophysical survey on parts of the El Toro property which also covered the Hunter Basin area that included Idaho (093L 040), King (093L 041), Hunter (093L 042), Colorado (093L 043), Rainbow (093L 044), Tribune (093L 255) and Hannah (093L 080).
The 2008 El Toro program of Lions Gate Energy Inc conducted 1495 line kilometre airborne magnetic and electromagnetic geophysical survey covered the Hunter Basin area that included Idaho (093L 040), King (093L 041), Hunter (093L 042), Colorado (093L 043), Rainbow (093L 044), Tribune (093L 255) and Hannah (093L 080). A sample (14551) from the Idaho occurrence area assayed 30.6 per cent copper, 1.79 grams per tonne gold and 1886 grams per tonne silver (Pautler, J. (2009-07-15): Technical Report on the El Toro Project).
The actual Idaho showing was relocated in 2009 and sampled. The sample yielded 3.3 per cent copper, 1.19 gram per tonne gold and 46.5 gram per tonne silver from quartz veinlet type mineralization (sample 13513) and 7.78 per cent copper, 2.65 grams per tonne gold and 126 grams per tonne silver from fracture fillings (sample 13514) hosted in amygdaloidal andesite volcanic rocks (Assessment Report 31515). Minor mineralization was traced for 125 metres at 065 degrees, but generally appeared narrow.
