The Bizar showing is located on the Bizar 1-4 and Biz claims (Goldstrike Group), 2.7 kilometres west of Tumtum Lake in the upper Adams drainage. It is 16 kilometres northeast of the village of Avola.

This showing was discovered by prospector/geologist Leo Lindinger in 1998, under the Prospectors Assistance Program. The showing is exposed on an overgrown logging road, however, there is no record and minimal evidence of any previous exploration work in the area. A 50 by 20 metre roadcut exposes a small stockwork zone of quartz-pyrrhotite-pyrite-chalcopyrite veinlets with attitudes of predominantly 300 degrees, 40-90 degrees north to vertical and 360 degrees, 30 degrees east. About 2 to 4 veinlets per metre are present, ranging from 1-3 centimetres in width. The largest vein is about 20 centimetres wide and contains up to 50 per cent sulphides in places, mainly pyrrhotite, pyrite and lesser chalcopyrite.

The veins are hosted in micaceous quartzite and quartz-muscovite-biotite schist of the Shuswap Metamorphic Complex (mapped as Unit 1c of Wheeler). The foliation of the schist dips moderately to the northeast and strikes at about 300 degrees at the showing. Pegmatite dikes, granitic rocks (mid Cretaceous) and gneiss are also common in the general area.

A semi-concordant layer of auriferous massive pyrrhotite and minor chalcopyrite, up to 20 centimetres wide, occupies the west end of the discovery showing.

The layer is concordant with synmetamorphic foliation and has been deformed together with the schists into southerly plunging crenulation folds. Tight fracture and narrow grey quartz veins trend northerly and dip steeply, crosscutting quartzite and schists.

High grade gold values are found in massive sulphide where it is associated with bismuth. The veins carry anomalous values in gold.

A 20-centimetre chip sample of quartz-sulphide vein breccia assayed 56.8 grams per tonne gold, 5.4 grams per tonne silver, 6 ppm arsenic, 5270.5 ppm bismuth, 151 ppm cobalt, 3423 ppm copper, 13 ppm molybdenum, 140 ppm nickel, 11.3 ppm selenium, 11.8 ppm tellurium, and 18 ppm tungsten. A 5-centimetre chip sample of massive sulphide vein assayed 11.69 grams per tonne gold, 2.2 grams per tonne silver, 36 ppm arsenic, 769 ppm bismuth, 318 ppm cobalt, 1939 ppm copper, 30 ppm molybdenum, 292 ppm nickel, 4.8 ppm selenium, 1.5 ppm tellurium and 60 ppm tungsten. Values for arsenic, antimony, mercury, lead, zinc, cadmium and tin are low. (Mike Cathro, December 1998).

Cassidy Gold Corp. optioned the Goldstrike group in December 1998 and conducted drilling (5 holes) in 1999.
