The BA project is a silver-base metal project located in the “Golden Triangle” area within the Skeena Mining Division of British Columbia The main BA property, is approximately 9,489.42 hectares in size, hosts numerous mineralized showings including the BA occurrence, a significant transitional volcanogenic massive sulphide (VMS) / epithermal hot spring deposit containing silver, lead and zinc. The property is located 30 km northeast of the town of Stewart, B.C. with Highway 37A passing through the northern portion of the property.
Mountain Boy Minerals Ltd and Great Bear Resources Ltd each own a 50 % interest in the BA claims.
The BA project hosts numerous types of precious and base metal mineralization. These include vein and shear hosted mineralization, disseminated and stringer micro-vein style mineralization, skarn mineralization, laminated stratabound mineralization and hydrothermal breccia mineralization. The main area of exploration hosts a silver rich volcanogenic massive sulphide (VMS) system that has been drill confirmed for 800 meters of mineralized strike and down dip for 300 meters.
Stratabound mineralization and related breccia zones with copper, zinc, lead and silver mineralization have been found throughout the claims and are the most promising targets on the claim group. The showings generally occur within mixed mudstone (argillite), volcanic tuff and breccia horizons. Sulphides include pyrite and/or pyrrhotite, chalcopyrite, sphalerite and galena. Quartz, chert, jasper, hematite, and barite are common gangue minerals. The sulphides occur as massive to semi-massive, laminar, lenticular, stringers and disseminations. On the project, at least 5 zones of silver-base metal mineralization have been identified. These include the BA, BA North, Wet Willy, Bod and Nelson occurrences.
Drilling in 2010 on the main BA and BA North Zones has identified three styles of mineralization including the following;
- carbonate + quartz + sulphide barite veining and brecciation within what is believed to be a subvolcanic andesitic intrusion and the surrounding intruded volcaniclastic and mudstone pile.
- replacement and quartz + sulphide flooding within the matrix of the volcaniclastics.
- laminated fine grained sulphide within mudstones and siltstones.
Highlights of drilling to date in 2007 and 2010 include the following:
|DDH NUMBER||WIDTH (m)||PB %||ZN %||AG g/t|
In addition to drilling and surface sampling, channel trench sampling in 2010 and 2011 produced the following results:
|Zone Location||Channel width||Pb %||Zn %||Ag g/t|
Work also outlined new zones for further exploration. 32 grab samples taken from the Nelson zone, located 5 kilometres east of the Main zone on the BA claims, returned assay results that ranged from below detection limits to a maximum of 173 g/t silver, 0.20 % lead and 5.5 % zinc, with an average of 39.5 g/t silver, 1.1 % lead and 1.25 % zinc. These results define a silver-lead-zinc mineralized sulfide-rich gossan exposed for 200 metres of strike and 200 metres down-dip along slope. The zone remains open along strike in both directions.
