The Hudson Bay prospect is centred on the Fram (Lot 9273) and Nansen (Lot 9274) claims, at about 1890 metres elevation, in the Sapphire Lakes area, 17 kilometres east of Slocan City. Access is about 5 kilometres by trail from the eastern extension of the Lemon Creek road. The property is located in Kokanee Glacier Provincial Park.

The Fram and Nansen claims were Crown granted to the Hudson's Bay company in 1909. The principal development on this property are two short adits connected by a vertical raise.

The rock of the area is typical of the main phase of the Nelson granitic batholith. However, in the immediate vicinity of the showings, the granite is brown to reddish brown in contrast to the characteristic grey of the surrounding Nelson rocks. This zone is about 30 metres wide and strikes slightly east of north on the east side of a small draw beside the adits. The exact structural nature of this red granite was not determined but it appears to be a later alteration phase of the original granite that follows a general line of weakness within the main granite mass. On the floor of the draw in the ordinary granite, lamprophyre dikes are exposed which vary in width from 0.5 to 1 metre and strike generally north parallel to the trend of the granite.

The lower adit was driven 060 degrees on a mostly steeply dipping quartz stringer which, at 7 metres from the portal, intersects a similar vein striking 020 degrees, dipping 35 to 50 degrees northwesterly. From the portal the original stringer gradually widens to 20 centimetres at the raise where it displays a section of well banded quartz heavily mineralized with sulphides. At the face, this vein structure, represented by 76 cm of shearing, includes a 10-centimetre width of quartz, some additional quartz stringers and almost no sulphides. However, at a point 18 metres from the portal, a short crosscut driven a short distance to the east, intercepts an additional quartz vein, enriched in sulphides, that strikes 010 degrees and dips vertically.

The vein in the upper drift adit ranges in width up to 28 cm wide, strikes almost north and dips steeply. Continuity of the vein is well maintained over the 40-metre length of the drift and sulphide mineralization is consistent, except close to the face where the vein pinches to a 3.5-centimetre quartz stringer bounded by one to several centimetres of shearing.

Sampling of weak pyrite and galena mineralization at the face of the lower adit across the 60-centimetre wide vein and accompanying shear zone yielded 3.4 grams per tonne gold and 45 grams per tonne silver.

In the upper adit, at 25 metres from the portal, a 28- centimetre wide sample of the quartz vein, well mineralized with galena and pyrite, assayed 1.4 grams per tonne gold and 290 grams per tonne silver.

A vein sample taken in 1987 assayed 2.4 grams per tonne gold, 490 grams per tonne silver, 0.26 per cent lead and 0.3 per cent zinc (Open File 1988-11).
