The Poplar Property encompasses over 620 square kilometres (62,000 hectares) and is contiguous to the south of one of Tasca’s newly acquired Nadina claim blocks. It is also on strike to the west of New Nadina’s Silver Queen property.
The Property has a long past of historical exploration including the drilling of 147 holes. This drilling identified an historic indicated mineral resource of 131 million tonnes grading 0.31% Cu, 0.009 % Mo, 0.09 g/t Au and 2.39 g/t Ag and an historic inferred mineral resource of 132 million tonnes grading 0.27 % Cu, 0.005 % Mo, 0.07 g/t Au and 3.75 g/t Ag.
These historic indicated and inferred resources were disclosed by Lions Gate Metals Inc. in its technical report dated March 30, 2012 prepared by Gary Giroux, P.Eng.
To determine the historic resource, a three-dimensional solid was constructed to constrain the mineralized area, using a 0.1 % Cu grade shell as a guide. Large internal waste zones were modelled as were some larger post mineral dykes. Of the total data base, 129 drill holes totalling 37,205 m were within the mineralized zone and were used to estimate the resource. Drill holes were compared to the mineralized solid and assays were tagged if inside. Copper, molybdenum, gold and silver assays within the mineralized solid were capped at 1.4 % Cu, 0.14 % Mo, 0.34 g/t Au and 41 g/t Ag respectively. Five metre composites were formed and used for variography.
For this estimate and to aid with some preliminary planning, the blocks were reduced to 5 x 5 x 10 m in dimension and were estimated for Cu, Mo, Au and Ag by ordinary kriging. The historic resource is classified as Indicated and Inferred based on each block’s proximity to data and the grade continuity. The historic indicated and historic inferred resource uses the categories set out in Section 1.2 of NI43-101.
Tasca will need to review and verify the historic drilling database and twin a number of the existing drill holes to bring the historic resources current. Investors are cautioned a qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves and therefore Tasca is not treating the historical estimate as current mineral resources or mineral reserves.
The underlying geology of the Poplar Property is largely Cretaceous Kasalka Group andesitic volcanics intruded by lower Cretaceous Bulkley Suite intrusive stocks. Lower Jurassic Hazelton Group Telkwa Formation calc-alkaline volcanics are in fault contact in the northeast. Outliers of Eocene Ootsa Lake Group volcanics overlap the Cretaceous rocks.
