The Boundary prospect is located at about 1128 metres elevation on the eastern slopes of Cranberry Ridge, 3 kilometres northwest of Beaverdell, British Columbia. The Lucky Boy occurrence (082ESW152) is located about 500 metres west on the Lucky Boy claim group. There are no previous records of the exploration and development work at the Boundary prospect. In 1988, the occurrence was held on ground staked by Dryden Resources Corp. During 2007 through 2009, Intigold Gold Mines Ltd. completed programs of rock and soil sampling and am airborne geophysical survey on the area as the Beaverdell property.

The hostrocks underlying Cranberry Ridge, immediately west of Beaverdell, are similar to that underlying Mount Wallace to the west. Granodiorite of the Jurassic Westkettle batholith, grading to quartz diorite and diorite, underlies most of Cranberry Ridge. To the immediate north, the Westkettle batholith has intruded Permian Wallace Formation metavolcanics and metasediments, now present as roof pendants. Lithologies include greenstone, quartzite, greywacke, limestone and local paragneiss. Younger Eocene intrusions of granite to granodiorite or quartz monzonite to syenite composition and associated dikes have intruded both Westkettle granodiorite and Wallace Formation rocks.

The Boundary prospect consists of one 15-metre adit along 260 degrees, one shaft of unknown depth and ten trenches. Outside the adit a 0.60-metre wide quartz vein was traced for 6.5 metres. The vein strikes 200 degrees and dips vertically. A 5-centimetre wide seam of massive galena occurs along the western edge of the vein. Other mineralization includes disseminated pyrite, galena and chalcopyrite. The vein is offset by a shear zone striking 260 degrees and dipping vertically. The adit follows the shear zone.

A 60-centimetre chip sample of the vein and galena seam yielded 28.46 grams per tonne silver, 2.28 per cent lead and 1.58 per cent zinc (Assessment Report 17921). Four samples taken from the shear zone yielded up to 2.42 per cent lead and 1.60 per cent zinc (Assessment Report 19721). Three samples were also taken from a small dump of trench material, 150 metres west of the adit. Sample R-15 yielded 6.86 grams per tonne gold, 46.63 grams per tonne silver, 0.06 per cent copper and 0.11 per cent lead (Assessment Report 17921).
