Opportunity:The property hosts a district-scale silver-rich VMS system. A portion of that system has been tested with 180 drill holes which have outlined a substantial silver-lead-zinc deposit with favourable grades. Over the coming weeks, the substantial data set on the project will be compiled, updated and re-evaluated as a basis for planning further work on the project and/or securing a joint venture partner.
Location:30 kilometres northeast of Stewartlocated in the “Golden Triangle” area within the Skeena Mining Division of British Columbia; Highway 37A passes through the northern portion of the property.
Ownership:Mountain Boy Minerals Ltd and Great Bear Resources Ltd (GBR) each own a 50 % interest in the BA claims. Mountain Boy is in the process of purchasing GBR’s 50% interest regain a 100% interest in the project.
Overview:The Barbara silver-lead-zinc zone was discovered in 2005. Mountain Boy acquired the property and drilled 93 holes between 2006 to 2008. The drilling confirmed the presence of ore grade mineralization with promising size potential. The best single interval assay was 3.05 metres of 1,215 g/t silver, 1.01% lead and 2.26% zinc in hole number BA-2007-01.
Great Bear Resources entered into an option agreement in 2010 to earn a 50% interest in the BA Property by spending $5.5 million on the project. After achieving it’s earn-in, Great Bear shifted attention to its Red Lake Ontario project and agreed to sell its interest in BA back to Mountain Boy.
The Barbara zone is part of an exhalative system with associated zinc-lead-silver mineralization. The main exhalite horizon is up to 50 metres wide and can be traced for at least one kilometre. Drilling by Great Bear tested the mineralized zone for 430 metres. They also tested several other promising target zones on the project that add potential to greatly expand the scope of the project.
Results of the work to date will be comprehensivly reviewed as a basis a planning the next phase of work on the project, which may involve a joint venture partner.
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.
