The Blitz showing occurs 4.7 kilometres southeast of Whistle Creek, 7.5 kilometres southwest of Hedley.

Thinly-bedded black argillite, with minor interbedded limestone, tuff and cherts of the Upper Triassic Stemwinder Mountain Formation (Nicola Group) outcrops atop a north-trending ridge between Pettigrew Creek to the west and various tributaries of the Similkameen River to the east. These sediments are locally veined and flooded with quartz.

Pyrite, arsenopyrite and chalcopyrite occur in zones of silicification and quartz flooding. Anomalous gold values were obtained from siliceous argillite containing disseminated pyrite and arsenopyrite, exposed in several old trenches dating back to the 1930s. Samples R83519 and R83518 analysed 3.53 and 2.69 grams per tonne gold respectively (Assessment Report 15441, page 7).
