Grande Portage Resources Ltd.: 14 Drillholes Completed From 3 Drillsites at Marten Showing; Massive Sulphides Intersected in 11 Holes
Wednesday July 4, 8:00 am ET
VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - July 4, 2007) - Grande Portage Resources Ltd. (TSX VENTURE:GPG - News; "Grande Portage" or "the Company") is pleased to announce that it has thus far completed 14 diamond drillholes from 3 drillsites all located at the Marten Showing, a step out of approximately 250 metres south of the former open pit magnetite mine on the Merry Widow project, northern Vancouver Island.

11 drillholes, to date, have intersected multiple zones of massive sulphide and massive magnetite mineralization. The thickness, number of zones per hole and constituent mineralogy varies considerably with each hole. The thickness of the zones range from less than 1 metre up to 4 metres. The mineralization is comprised of either massive magnetite lenses with lesser chalcopyrite, pyrrhotite and pyrite; or massive sulphide lenses comprised chiefly of pyrrotite, with lesser chalcopyrite, pyrite, arsenopyrite and cobaltite.
These holes have been designed to explore the copper-gold-cobalt-silver massive sulphide mineralization hosted in the wall rocks and in the periphery of the magnetite skarn. Three drill stations were established and holes were drilled either at steep angles to assess the down dip potential or were fanned out at different bearing angles to determine the mineral variability along strike. By undertaking a drill program in this manner, the company lowers its costs with fewer setups and attains a greater geological understanding within a contained area.
All samples are prepared at ALS Chemex's facility in North Vancouver, B.C. All samples are analysed by ICP methods, ME-ICP61m. This involves four-acid digestion of the sample and analysis of 33 elements plus mercury with a mass spectroscopy finish. In addition gold, silver, copper and cobalt are analysed by fire assay of a 30-gram pulp with a gravimetric finish with the results expressed in grams/tonne.
