Grande Portage Resources Ltd.: Merry Widow Continues to Yield High Grade Gold Values Over Long Intersections
Thursday August 31, 4:35 pm ET


VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Aug. 31, 2006) - Grande Portage Resources Ltd. (TSX VENTURE:GPG - News; "Grande Portage" or "the Company") is pleased to report initial gold assay results from drill holes MW06-05 to MW06-08. These holes were drilled from the same drill setup site located along the access ramp to the Merry Widow open pit. Drill holes MW06-05 and MW06-06 were located to verify results obtained from diamond drilling in 1989 and 1990 by previous operators, drill holes MW06-07 and MW06-08 were new holes drilled parallel to drill holes MW06-02, 03, 04 (which were reported in the company's news release of August 29, 2006) to add to the geological database knowledge, and to provide drill core for metallurgical test work.

The drill holes successfully intersected massive sulphide skarn mineralization containing visible pyrrhotite, pyrite and chalcopyrite hosted in either massive magnetite or epidote-garnet-actinolite skarn assemblages. Significant gold results were obtained from DDHMW06-08 which intersected 62.21 meters with a weighted average of 5.29 grams per tonne gold (including 79.40 grams per tonne gold over 1.15 meters, 54.30 grams per tonne gold over 1.16 meters and 18.85 grams per tonne gold over 1.00 meters) and from DDHMW06-07 which intersected 40.95 meters with a weighted average of 6.57 grams per tonne gold (including 53.90 grams per tonne gold over 1.00 meter, 23.40 grams per tonne gold over 0.48 meters and 19.95 grams per tonne gold over 1.17 meters).

A summary of the drill hole locations and orientations with significant results of gold are displayed below. The Company has not received assay results for copper, cobalt and silver. These assays are awaited and will be released once they have been received tabulated and reviewed by management. The drill core was analyzed by ALS Chemex, the values displayed are weighted averages of the intersected zones and are not true widths, gold is reported in grams per tonne. Note that where reported gold values were less than 0.05 gram per tonne, and a value of 0.01 gram per tonne was used to calculate the weighted average of the interval reported, and individual intercepts are assay values over the sample interval.

The Company has established threshold values geochemically for silver greater than 10 ppm, copper greater than 1000 ppm and cobalt greater than 500 ppm in which any value received above this will be analyzed by fire assay. This has created a slowdown in receipt of assay results because there were multiple intersections reporting above threshold in silver, copper and cobalt.

The gold assay values for the next drill holes are anticipated early next week and will be reported when available. It is hopeful that further assays of silver, copper and cobalt will also be available.

The exploration program is being conducted under the direction of Warren Robb, P.Geo. and George Nicholson, P.Geo., both qualified geologists as defined under National Instrument 43-101.
