Grande Portage Resources Ltd. Announces Helicopter Airborne Geophysical Survey Now Underway.
Data Indicates Intrusive body almost 10 kilometres in Diameter.

VANCOUVER, BC, June 9, 2006 -- Grande Portage Resources Ltd., (TSX-V "GPG") ("Grande Portage" or "the Company") is pleased to announce that it has received confirmation from Aeroquest Limited that the Helicopter Airborne Magnetic and Time Domain EM Geophysical survey will commence the weekend of June 10th and should be completed within a week. A total of 1125 line kilometers plus tie lines are currently scheduled to be flown. Initial results will be available following the completion of the survey.

Past work on the Merry Widow Massive Sulphide project has focused along a limited strike length in and around the former producing Merry Widow magnetite iron-ore mine and Cominco's Coast Copper Mine (copper-gold-silver-cobalt-magnetite). All mineralization is associated along the eastern flank of a gabbrodiorite intrusive stock.

Previous government airborne magnetic data indicates that this intrusive body has a diameter of almost 10 kilometers. Grande Portage is hopeful that the detailed airborne geophysics being undertaken will assist in locating other potential zones of mineralization proximal to or within the intrusive core. Initial results from the survey will be followed up by geological evaluation followed by more detailed surveys as warranted. Further analysis and 3-D modeling of airborne data will also ensue over the upcoming weeks.
