Prospecting by Camille Berube and Dave and Len Piggin has located several new small W-Bi-Zn, W and W-Au showings on the Lucky Bear claim group near East and North Barriere Lakes. The showings are within, or adjacent, to the mid-Cretaceous Baldy batholith.

The "Little Creek" W-Au showing is hosted by sericite- and biotite-altered granodiorite. Steeply dipping, north-trending, sheeted quartz veinlets range up to 10 centimetres in width in a 10 metre-wide blasted roadcut exposure. The veinlets contain minor sericite and pyrrhotite. Ultraviolet lamping has identified scheelite grains up to 1.5 centimetres long which occur in scattered patches in the veins, and selected samples collected by the owners have returned up to 6.15 per cent tungsten (D. and L. Piggin, written communication, 1999). One chip sample contained 370 ppb gold over 2 metres; otherwise the results were not significant for gold, bismuth or tungsten, confirming that tungsten, at least, is very irregularly distributed (Fieldwork 1999, page 210, 211).

Approximately 500 metres to the east at the "Flat Rock" W showing is an irregular, half-metre-wide quartz vein with 1-3 per cent pyrrhotite and traces of chalcopyrite and scheelite. The vein is hosted by quartz-feldspar-biotite gneiss, part of the Devonian Orthogneiss (Schiarizza and Preto, 1987). A grab sample of the vein ran 1480 ppm tungsten (Fieldwork 1999, page 210, 211) and selected samples taken by the owners ran up to 0.39 per cent tungsten, 80 ppb gold, and 135 ppm bismuth (L. and D. Piggin, written communication, 1999).

Scheelite-bearing pegmatite and garnet-tremolite-biotite-quartz skarn boulders ranging from 30 centimetres to 1 metre in diameter are found 2 kilometres to the northeast of the Little Creek showing in the "Water Tank" area (UTM 11 0314806E 5690793N). A grab sample of one of the skarn float boulders returned 0.437 per cent tungsten, 205 ppm bismuth and 1515 ppm zinc (Fieldwork 1999, page 210, 211). Although this mineralization has not yet been found in outcrop, the boulders suggest that skarn and pegmatite-hosted tungsten mineralization is associated with the margin of the Baldy batholith.
