Rocks in the area belong to the Mesozoic Hazelton Group and have been folded on a regional northwest-southeast axis, cut by faults and selective tectonism, locally hydrothermalized and intruded by plugs of both Cenozoic and Mesozoic Age.

Locally, Lower Jurassic Hazelton Group volcanic and sedimentary rocks of the Unuk River Formation are unconformably overlain by the Middle Jurassic marine and non-marine volcanics and sediments of the Betty Creek Formation, the volcano-sedimentary Upper Jurassic Salmon River Formation, and the post-accretion fine clastic basinal Nass Formation.

The Unuk River Formation forms a north-northwest trending belt and consists of red, green, and purple volcanic breccia, conglom- erate, sandstone, siltstone, and minor tuff with limestone. Also included are pillow lavas and volcanic flows. These rocks are over- lain by both the Betty Creek and Salmon River Formations, respective- ly.

The Betty Creek Formation consists of pillow lavas, breccias, and andesitic and basaltic flows. The overlying Salmon River Formation consists of banded siltstone, sandstone, calcarenite, limestone, volcanic sediments and flows.

Intrusives are dominated by granodiorite of the Coast Plutonic Complex to the west. Some of the small intrusive plugs on the claims range from quartz monzonite to granite. Small Tertiary feldspar porphyry dykes, sills, and small plugs intrude the rocks and host related quartz-sulphide and epithermal metalliferous deposits.

Mineralization occurs in a quartz vein which cuts the Hazelton Group rocks. The vein strikes 015 degrees over a length of about 10 metres and hosts massive galena with sphalerite and pyrite. A sample assayed 1.96 grams per tonne gold, 1790.0 grams per tonne silver, 4.45 per cent lead, 2.45 per cent zinc, and 0.26 per cent copper. Another quartz vein hosting massive galena was sampled over 1.0 metre and assayed 0.58 grams per tonne gold, 1580.0 grams per tonne silver, 2.86 per cent lead, 0.93 per cent zinc, and 0.34 per cent copper (Assessment Report 16155).

A sample of massive sphalerite and galena is interbedded within a schist that strikes 040 degrees. A sample taken over a 1.0 metre area assayed 0.21 grams per tonne gold, 238.0 grams per tonne silver, 5.35 per cent lead, 22.5 per cent zinc, and 0.35 per cent copper

Samples taken from a gossanous area approximately 60 metres long and 1 to 3 metres wide, hosting disseminated pyrite throughout assayed 1.35 grams per tonne gold, 604.3 grams per tonne silver, 0.16 per cent lead, 0.22 per cent zinc, and 0.06 per cent copper (Assessment Report 16155).
