The Big Hammer property covers the lower slopes of the Thornhill and Attree mountains on the north side of Williams Creek, 13 kilometers southeast of Terrace. The property consists of six tenures which have a total area of 1,617 hectares (3,996 acres). Road access to the property is all season and work is feasible on a year-round basis.
Big Hammer occurs along the western margin of the Intermontane Belt, adjacent to the Coast Crystaline Belt. Basement rocks include Carboniferous intrusive which, in turn. includes the andesites, basalt breccias, and basalt flows of the Mt. Attree Volcanics. The basement rocks are intruded by Late Jurassic granodiorite and granite of the Kleanza pluton and the non-foliated Eocene granite of the Williams Creek Pluton. The mineralization occurs within in a late Carboniferous, Mississippian intrusive unit which is foliated diorite, granodiorite, tonalite and metagabbro.
Big Hammer’s Au-Ag-Te mineralization was first discovered on new logging road cuts in 2007 within a thick series of sheeted, low-angle quartz-pyrite veins. Host rocks are Carboniferous granitics and possibly altered basement volcanics. The multiple Big Hammer Au-Ag-Te showings are also anomalous in lead (Pb), copper (Cu), zinc (Zn), cobalt (Co) and tungsten (W).
A sulphidic zone at 800 meters elevation and approximately 5m thick, has similar geometry to the 380 and 625 veins. Silver and also cobalt, cesium, rhenium and selenium are anomalous in the 800 vein.
Work to date on the Big Hammer property includes an extensive exploration and trenching program that produced significant assay results from the 397 samples tested. Based on these results, additional exploration and diamond drilling will be immediately undertaken.
