Since 2004, the Company's second principal area of interest has been in the Atlin region of northwestern British Columbia. The Atlin Property consists of two properties currently referred to as the Atlin Project and the Tagish Lake Project (including the Wann River Project). In both cases, the areas claimed by the Company since 2004 have grown in size and, as a consequence, previous names of individual claims blocks have necessarily changed to reflect the size of individual blocks.
WANN RIVER PROJECT, TAGISH LAKE, BC
The 67,055.9 hectare Tagish Lake Project, is located primarily between Tagish and Atlin Lakes, 15-35 km west of the community of Atlin in the Atlin Mining Division of northwestern British Columbia. Atlin is approximately 180 km by road southeast of Whitehorse, Yukon Territory.
Geology
Two crustal scale sub-parallel, northwest trending faults transect the Tagish Lake Project, the Nahlin Fault Zone in the northeastern property area and the Llewellyn Fault Zone through the Wann River area. The faults are grossly coincident with terrane boundaries. A belt of anomalously high regional gold-arsenic and antimony geochemistry extends the length of the Tagish Lake area, coextensive with the Llewellyn fault.
The Tagish Lake Project is underlain by Carboniferous to Triassic oceanic rocks of the northern Cache Creek Terrane to the east of the Nahlin Fault Zone, Devonian to Permian metamorphic rocks of the Yukon-Tanana Terrane to the west of the Llewellyn Fault Zone and Triassic to Jurassic sedimentary strata of the Whitehorse Trough between the faults. The above lithologies are cut by Late Cretaceous to Tertiary intrusions and intruded by Eocene plugs and dykes and overlain by associated volcanic rocks and basal coarse clastic sedimentary rocks of the Sloko Group.
Potential exists within the Tagish Lake Project for epithermal gold-silver (Engineer Gold Camp), polymetallic vein (Ben-My-Chree), gold quartz vein (potential in Graham Creek area), copper (Whitehorse Copper) and gold skarn (TP in northern Tagish region) deposits, and possible Kuroko-style volcanogenic massive sulphide (Tulsequah Chief) deposits within Yukon-Tanana Terrane and copper-molybdenum-gold porphyry and gold-silver rich Eskay type shallow subaqueous hot spring deposits within the Whitehorse Trough.
Seven Minfile occurrences are documented on the Tagish Lake Project, the Kim (109.7 g/t Ag, 0.7 g/t Au and 4.0% Cu) and Douglas polymetallic vein showings in the southwestern property area, the Kirkland showing and Gleaner prospect covering epithermal veins near the Engineer Mine, the Graham Creek placer and upstream extent in the northern property area, and the Brown polymetallic vein showing and the copper-nickel-platinum-palladium Anyox-Rodeo prospect within the Wann River area.
Exploration
Exploration by Blind Creek Resources Limited has focused on the Wann River area which straddles the Llewellyn Fault Zone, a system of northwest trending, steeply northeast dipping structures. A 160° trending 800m long by 180m wide corridor with quartz vein mineralization has been identified with Devonian to Triassic Boundary Range biotite-feldspar-quartz schist in the southwest, and a faulted panel of Upper Triassic Stuhini andesite and quartz eye porphyry in the northeast.
Mineralization at the Brown showing within the corridor consists of tetrahedritefreibergite, chalcopyrite, malachite, azurite, molybdenite, pyrite, sphalerite and galena. A sample collected from the Brown adit by the author in 2010, returning 8.6 g/t Au and 420 g/t Ag over 0.3m, confirmed previous results by the British Columbia Geological Survey from a chip sample (assaying 8.6 g/t Au and 315.38 g/t Ag) and verified the presence of significant gold-silver values on the Wann River portion of the Tagish Lake Project.
2010 Exploration at Wann River
Results from grab samples from the Wann River area include 263 g/t Au, 1350 g/t Ag, 2.75% Cu, 4.45% Pb and 1.36% Zn hosted by quartz from tailings in the Lum trenches, and 15.9 g/t Au, 440 g/t Ag, and 1.04% Pb from the Newfie, 17.2 g/t Au from the Trail, including 32.9 g/t Au, 1180 g/t Ag and 3.35% Cu and 3.79% Pb from float, and 126 g/t Ag from the River quartz vein showings.
Based on the widespread indications of precious and variable base metal mineralization within a prospective 800m by 180m wide corridor, association with the Llewellyn Fault Zone, lack of overall exposure, and proximity and similarities to the past producing Engineer Mine, the Technical Report on the Tagish Lake Project recommended a significant exploration program on the Wann River portion of the Tagish Lake Project. A program consisting of 2,000m of diamond drilling to evaluate the southeastern sector of the corridor, a ground magnetic geophysical survey to aid in geological mapping, and additional prospecting, mapping and sampling was recommended on Wann River with a budget of $950,000. A budget of $50,000 was recommended to evaluate the Engineer portion by mapping, prospecting and sampling.
