Bitterroot Begins Drilling GK Gold Project

 Bitterroot Resources Ltd. (symbol BTT on the TSX-Venture Exchange) has mobilized a drill rig to its 100 percent-owned GK Gold project in the Boundary District of south-central British Columbia. The drilling program will test for bulk-mineable, stockwork-hosted, gold-copper mineralization in the Hornet zone and in the recently identified HTB zone. The drilling program will include a minimum of 1,500 metres of core drilling in six holes.

Drilling will test two near-surface Induced Polarization (IP) chargeability highs coincident with magnetic lows, which may reflect focused zones of hydrothermal alteration. Both IP targets are approximately 300 metres wide and at least 700 metres long. In 2007 and 2010, drilling and trenching at the Hornet zone identified five high-grade, gold-bearing quartz veins on the periphery of the untested IP anomaly. Four drill holes intersected gold-mineralized quartz-chalcopyrite-pyrite veins and tourmaline-bearing intervals which dip toward the IP anomaly, returning assays of up to 1.47 grams Au/tonne over 13.9 metres of silicified, brecciated diorite cut by quartz-sulphide veins. Channel samples returned assays of up to 22.1 grams Au/tonne over 5.2 metres.

The road-accessible, 177 square-kilometre GK property covers an assemblage of tuffaceous volcanic and sedimentary rocks cut by diorite intrusions and dykes of alkaline to calc-alkaline affinity. Most anomalous gold values occur within extensively brecciated and silicified intervals associated with contacts between tuffs and diorite intrusions. Typically, the higher gold values coincide with an increased abundance of sulphide minerals, with the most anomalous results clearly associated with arsenopyrite and chalcopyrite.

Approximately one-quarter of the GK property has been systematically tested by soil geochemistry, which defined the Hornet Zone as a large gold-arsenic anomaly coincident with an IP chargeability high. Mapping, prospecting and sampling programs are planned for this summer to test other prospective parts of the property that host anomalous gold in stream silts and soils. Mr. Charles Greig, P.Geo is the Qualified Person responsible for the design and implementation of exploration programs on the GK project.
