Bitterroot Resources Ltd. has completed five diamond drill holes totaling 1,115 metres on two conduit-hosted magmatic nickel/copper/platinum/palladium (Ni-Cu-PGM) targets. This drilling is part of a planned 2,500-metre drilling program to test for Eagle or Tamarack-type targets on the Company's 100 percent-owned mineral rights in the Upper Peninsula of Michigan.
Target "N" was tested with 583 metres of drilling in three holes. Two conductive zones are caused by graphitic sulphide-rich sediments in contact with unmineralized mafic intrusions. These occur within a prospective 100 square kilometre area with mafic intrusions, metasedimentary host rocks and underlying basement in a setting similar to that of Lundin Mining Corporation's Eagle Mine.
On the Norwich Layered Intrusion, drilling of 532 metres in two holes at the west end of the intrusion intersected mafic intrusive rocks and underlying volcanic rocks within a gravity high which had been interpreted as a potential feeder zone to the intrusion. Subsequent geochemical analyses and down-hole electromagnetic geophysical surveys did not suggest the presence of a significant sulphide body within 100 metres of the drill holes. The cause of the gravity anomaly has not been definitively determined. Geophysical inversions are planned, utilizing the data gathered from drill core to determine if targets exist elsewhere in the 3 kilometre-long intrusion.
Bitterroot's management plans to drill-test two other high-priority Ni-Cu-PGM targets in Michigan prior to year-end. Land acquisition activities are continuing within this emerging Ni-Cu-PGM district.
Bitterroot Resources Ltd., through its Michigan subsidiary Trans Superior Resources, Inc., owns 100 percent interests in approximately 360 square miles of mineral rights in the Upper Peninsula of Michigan.
