The Pick Axe showing is 1.3 kilometres northeast of Highway 3, 2 kilometres northwest of Cahill Creek and 2 kilometres east-southeast of Hedley.

This occurrence is hosted in a sequence of siltstone, argillite limestone and chert of the Upper Triassic Hedley Formation (Nicola Group). The beds strike north, dip moderately west and are intruded by hornblende porphyry sills of the Early Jurassic Hedley Intrusions. The showing lies along the west flank of a granodiorite dyke-like apophysis of the Middle Jurassic Cahill Creek pluton.

A layer of massive pyrrhotite, chalcopyrite, arsenopyrite and pyrite, striking 025 degrees, is exposed over a length of 9 metres and a width of up to 0.54 metre. The massive sulphides are enclosed in a section of argillite, siltstone and skarned cherty sediments, lying between two sills of feldspar porphyritic andesite, possibly of the Hedley Intrusions. A sample of massive pyrrhotite, chalcopyrite, arsenopyrite and pyrite, with some chert, assayed 17.7 grams per tonne gold, 5.2 grams per tonne silver, 0.073 per cent arsenic, 0.054 per cent bismuth and 0.254 per cent copper (Assessment Report 16400, page 12, sample 1100). Six chip samples of massive sulphides, taken over widths of 0.35 to 0.50 metre assayed 4.05 to 37.03 grams per tonne gold, 3.1 to 9.6 grams per tonne silver, 0.001 to 0.118 per cent arsenic, 0.015 to 0.109 per cent bismuth and 0.092 to 0.251 per cent copper, respectively (Property File - S.L. Todoruk, C.K. Ikona, 1988, page 11, samples 14704-14707, 14709, 14710). A chip sample of interbedded argillite, chert and limestone with less than 1 per cent pyrrhotite and pyrite assayed 4.4 grams per tonne gold and 0.3 gram per tonne silver over 0.50 metre (Assessment Report 14879, assay certificate, sample HR 24). The sample was taken near the granodiorite contact.

A second zone of sulphide mineralization occurs 30 metres northeast of the Pick Axe showing on the southern part of the Norfolk claim (Lot 3539). A zone of garnet skarn (G zone) trends northeast for 30 metres in limestone and is up to 10 metres wide. The zone contains disseminated arsenopyrite, pyrrhotite and chalcopyrite in a gangue of garnet and calcite. One sample assayed 0.8 gram per tonne gold and 0.019 per cent copper (Assessment Report 16400, assay certificate, sample 5234). Four additional samples all assayed less than 0.17 gram per tonne gold (samples 5334 to 5337).
