The area of the Nok North occurrence is underlain by andesitic pyroxene porphyry flows and adesitic lapilli tuff, breccia and agglomerate of the Upper Triassic Stuhini Group. The east half of the Nok claims were underlain by Stuhini rock while the west were underlain by an Early Jurassic monzodioritic to gabbroic pluton of the Texas Creek Plutonic Suite. Monzonite and syenite of the Upper Triassic to Early Jurassic Copper Mountain Plutonic Suite (Galore Creek intrusions) intrudes the country rock near the east.

Pyrite, chalcopyrite, sphalerite and galena were found in quartz-carbonate veins up to 15 centimetres in width. These occur north of the Anuk River, along a tributary that formed along a southeast trending fault. Geochemical analysis of up to 0.02 per cent copper, 0.83 per cent zinc and 0.29 per cent lead, 3.4 grams per tonne silver and 26 parts per billion gold were derived from these veins (Sample 90G-22-W17, Assessment Report 21073). Another sample located about 200 metres upstream along the southeast flowing tributary graded 0.15 per cent copper and 1.2 grams per tonne silver (Sample 90G-22-W33, Assessment Report 21073).

In 1990, Consolidated Golden Trump Resources Ltd. and Acorn Resources Ltd conducted an exploration program on their Nok property that consisted of stream sediment silt sampling, prospecting, geological mapping, soil sampling, rock geochemistry and minor hand trenching. A total of 44 man-days were spent on the claims during which 529 soil samples, 40 stream sediment silt samples and 129 rock samples were collected. Approximately 11.8 kilometres of flagged grid lines were run while soil sampling, including 0.9 kilometres of base line. Soil samples were collected at 25 metre intervals.

Some Nok property work was located just north of the Anuk RB showings that were located from 1989 to 1991 on the Anuk property. See the Anuk Rb 14 showing (104G 047) for related information.
