The MB property is at the north end of Iron Range Mountain, 13 kilometres northwest of Kitchener. The claims are at the head of a small creek basin on the south side of Hall Creek, a tributary of Goat River, at an elevation of 1400-1500 metres.

The occurrence is a strong quartz-calcite vein containing minor amounts of galena, chalcopyrite and pyrite. The vein has an average width of 1.4 metres and has been exposed at intervals over a distance of 300 metres across the nose of the ridge west to the creek basin; the strike is 315 degrees and the dip 85 degrees southwest. The southeast end of the vein is approximately 150 metres west of the Iron Range Mountain fault. The vein is hosted in grey quartzite of the Aldridge Formation, and in one instance cuts across a diorite sill of the Moyie intrusions. Both these units are of Middle Proterozoic age, and belong to the Purcell Supergroup.

Two samples are reported; one across 0.9 metre width of mineralized vein assayed 0.25 per cent copper and 0.65 per cent lead (Minister of Mines Annual Report 1956, page 107).

During 2004 through 2012, Eagle Plains Resources Ltd. completed programs of geological mapping, geochemical (soil and rock) sampling and airborne geophysical surveys on the area as apart of the Iron Range property. A completed property exploration history can be found at the O-Ray (MINFILE 082FSE017) occurrence.
