Exploration Update
|
| | Michigan Uranium Joint Venture
Bitterroot Resources Ltd. and Cameco Corporation's US subsidiaries have been exploring for uranium in the Upper Peninsula of Michigan under an option/joint venture agreement since 2003. Cameco is in the process of earning a 65 percent interest in a 72 square-mile area of interest. Bitterroot, as project operator, has recently been notified by USDA Forest Service that permits for the next phase of drilling and geophysical surveys are subject to additional public comment. Based on current USDA Forest Service timelines, exploration is expected to resume in mid-2008.
North Brenda Molybdenum/Copper Project, BC
During October, Bitterroot's drilling contractor completed 1398 metres of drilling in five holes on the North Brenda property. The drill holes are located approximately one kilometre north of the formerly-producing Brenda Mine open pit (159 million tonnes grading 0.049% Mo and 0.183% Cu), which is 30 kilometres west of the town of Westbank, in south-central British Columbia. The holes were drilled from two setups, testing a portion of the northern extension of the Brenda Mo/Cu mineralized trend, which is defined by highly anomalous Cu/Mo values in soil, Induced Polarization chargeability anomalies and mineralized outcrops.
All five of the drill holes contain molybdenite/chalcopyrite-bearing veins and fracture-controlled mineralization with styles and orientations typical of mineralization previously documented in the Brenda deposit. Bitterroot's geological consultants interpret this part of the North Brenda property to be underlain by a northerly extension of the mineralizing system which generated the Brenda deposit. Farther north on the 100 percent-owned, 44 square-kilometre North Brenda property there are several other significant IP and geochemical targets which remain to be drill-tested.
Core-logging and sampling of the five North Brenda holes is expected to be completed in January, with assay results currently expected to be available in early 2008. Mr. Charles Greig, P.Geo is the Qualified Person responsible for the design and implementation of exploration programs on the North Brenda project. Analyses are being done at ALS Chemex in North Vancouver, BC, by ICP-AES and fire assay/AA.
GK Gold Project, BC
During November and December, Bitterroot's drilling contractor completed 3,428 metres of drilling in 17 holes. The Blue Jay zone was tested with 2,682 metres of drilling in 13 holes, while the Hornet zone was tested with 746 metres in four holes.
Drilling on the Blue Jay zone intersected sulphide mineralization in all 13 drill holes completed. Mineralization consists of sulphide-enriched vein-breccias and stockworks containing pyrite, arsenopyrite, quartz and carbonate, with subordinate tourmaline and chalcopyrite. Earlier in the year, trenching of the Blue Jay zone returned values of up to 6.75 grams Au/tonne over 9 metres within similar sulphide-mineralized rock (see BTT news release dated October 31, 2007). The Blue Jay Zone has been tested along a strike length of 250 meters and remains open along strike and down dip.
Drilling on the Hornet zone intersected sulphide mineralization in all four holes drilled. The mineralization at Hornet also consists of sulphide-enriched vein-breccias and stockworks containing pyrite, arsenopyrite, quartz and carbonate, with subordinate tourmaline and chalcopyrite. Trenching of the Hornet zone yielded values of up to 22.1 grams Au/tonne across 5.0 metres within similar sulphide-mineralized rock (see BTT news release dated November 12, 2007). Mineralization occurs in at least five sub-parallel, steeply dipping sulphide-bearing zones, the largest of which has a minimum strike length of 250 metres. All of these zones remain open along strike and down dip.
The 2007 GK drilling program was completed late last week and the drill has since been demobilized. Core logging, sampling and assaying are underway and are expected to be completed in early 2008. Charles Greig, P.Geo is the Qualified Person responsible for the design and implementation of exploration programs on the GK project. Analyses are being done at ALS Chemex in North Vancouver, BC, by ICP-AES and fire assay/AA.
Mineral Creek Gold Project, BC
During the second half of 2007, Bitterroot's joint venture partner, Mineral Creek Ventures Inc. extracted approximately 200 tonnes of mineralized rock from an adit driven on the Lower Linda vein. Mining activities have been temporarily suspended due to the onset of winter weather and are expected to resume in the spring of 2008. A test-milling gravity circuit is currently being designed and equipment is being sourced. Milling of material from the Lower Linda vein is expected to commence in the first quarter of 2008. In addition, drilling of other structurally-controlled gold targets and volcanogenic massive sulphide targets in the Sicker Group is planned to resume in the spring of 2008. Mr. Mike Becherer, P.Geo is the Qualified Person responsible for the design and implementation of exploration programs on the Mineral Creek project.
Big Southeaster Project, BC
During the past year, Bitterroot has drilled 40 holes totalling 11,286 metres on the Big Southeaster property. Of these, 22 holes (6,679 metres) tested targets associated with the gold-bearing Mineral Creek fault zone. Most of the assay results have been received, which have identified several hundred narrow quartz-carbonate vein, shear-breccia and fault-hosted intervals containing highly anomalous gold values (+0.2 grams Au/Tonne). Data compilation is currently underway.
The remaining 18 holes (4,607 metres) drilled on the Big Southeaster property tested polymetallic copper/zinc/gold mineralization in the Regina area. Drilling encountered basaltic flows containing sporadic chalcopyrite, sphalerite and massive pyrite intersections, sometimes associated with quartz veining.
Drilling has been temporarily suspended due to the onset of winter weather and is expected to resume in the spring of 2008. Core logging, sampling and assaying is expected to be completed in early 2008. Mr. John Wilson, P.Geo is the Qualified Person responsible for the design and implementation of exploration programs on the Big Southeaster project. Analyses are being done at Acme Analytical Laboratories Ltd. in Vancouver, BC, by ICP-MS and fire assay/ICP-ES.
