The area of the Nok SE 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 to the east.
Numerous quartz and quartz-carbonate veins up to 5 centimetres were found in the vicinity of the grid in the southeast portion of the Nok property in 1990. These veins contained bornite, hematite, pyrite, chalcopyrite and/or pyrolusite.
On a southeast portion of the grid, one of the quartz-carbonate veins yielded a sample that assayed 8.78 grams per tonne gold, 1.1 grams per tonne silver and 0.0262 per cent copper. Several other samples from this area (of about 200 by 200 metres) ranged from 0.04 to 0.12 per cent copper with two samples yielding 0.33 and 0.47 gram per tonne gold (Assessment Report 21073). However, most copper-bearing samples carried little to no significant values in gold.
In 1990, Consolidated Golden Trump Resources Ltd. and Acorn Resources Ltd. Conducted an exploration program 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 located from 1989 to 1991 on the Anuk property. See the Anuk Rb 14 showing (104G 047) for related information.
