Grande Portage Resources Ltd. To Explore Former Underground Mines Wardrop Engineering Inc. to Develop Strategic Plan
VANCOUVER, BC, November 6, 2007 -- Grande Portage Resources Ltd. (TSX-V GPG) ("Grande Portage" or "the Company") is pleased to announce that it has engaged Wardrop Engineering Ltd. to assist with the evaluation of environmental conditions at the Merry Widow open pit as well as the former underground workings of the Old Sport Horizon. Company representatives will be onsite with senior underground and environmental specialists from Wardrop this week.
The Old Sport Horizon was the host rock for two former producing underground mines-Coast Copper and Benson Lake. The mines produced appreciable amounts of copper, gold, silver, cobalt and iron over almost a decade before closing in late 1972 due largely to the low commodity prices at the time. From 1960-1973 these mines processed 2,621,131 tonnes of ore that yielded 90,814,161 lb of copper, 377,165 oz of silver, 124,386 oz of gold and 507,207 tonnes of iron. Airborne magnetic data has greatly helped to define the geological trend and related mineral showings and further associated copper-gold-cobalt targets.
The Company 's geological team has had the benefit of reviewing the underground data provided by former operators. As such, there is great enthusiasm surrounding this next phase of exploration aimed at accessing the Old Sport from an underground perspective. Grande Portage's helicopter airborne magnetic and time domain electro-magnetic geophysical survey outlined an 8.0 km long by up to 500 metres wide linear magnetic feature that coincides with the location of the Old Sport Horizon and the historic underground development.
Preliminary drill testing of this target was completed as part of the Company's 2007 exploration work on the Old Sport Horizon. Drill hole step-outs some 800 metres south of the underground workings intersected a magnetite-rich portion of the Old Sport Horizon at the basal contact of the Quatsino Limestone in the centre of the magnetic linear feature. The hole confirms that the magnetic feature represents the Old Sport Horizon. Additional airborne coverage completed in 2007 has extended the magnetic anomaly a further 1.5 km to the northwest, for a total length of 9.5 km, where it appears the magnetic trend terminates against an east-northeast trending magnetic low.
Grande Portage has been exploring the Merry Widow project under the premise that there exists significant remaining tonnage at the old open pits peripheral to the magnetite zones and in the Old Sport Horizon either along strike extensions or within the old workings. Substantial amounts of mineralized skarn material remain untested.
