The Denum occurrence is located on an unnamed creek east of Darb Creek, approximately 8 kilometres southeast of Johanson Lake. The showing occurs to the north of the KC (094D 140) occurrence and east of the Bruce (094D 013) occurrence. For a summary of the regional geology, refer to these occurrences.

Locally, the area is underlain by andesitic tuffs, minor intercalated greywackes and calcareous argillites, and hornblende or feldspar porphyry flows of the Upper Triassic Takla Group. These rocks are intruded by hornblende diorite, dioritic feldspar porphyry dykes and biotite hornblende monzonite porphyry phases of the Early Cretaceous Kliyul Creek body. Emplacement of the intrusive rocks appears to be controlled by a southeast trending splay of the Dortatelle fault (Assessment Report 13580). Alteration zones are formed where faults cut the andesitic rocks.

The Denum occurrence consists of malachite-stained quartz veins. These veins contain chalcopyrite and up to 40 per cent pyrite. The host rocks are predominantly epidote altered, andesitic tuffs (Map 1-4, Assessment Report 13580). The massive pyrite forms large, well-developed crystals within the quartz veins; chalcopyrite is noted (Map 1, Assessment Report 13580).

In 1984, Golden Rule Resources, explored the potential of gold-bearing quartz veins on their KC claims which included Independence (094D 028) and Banjo (Bap) (094D 029). Work carried out in 1984 consisted of reconnaissance rock and stream silt geochemical sampling, prospecting, geological mapping, and ground magnetometer surveying. They reported an extensive 70 degree striking, variably silicified, fracture zone hosting 0.2 metre to 1.3-metre-wide quartz veins in regions of intense fracturing and silicification. Cross-fracturing in the quartz veins were described as mineralized with up to 30 pyrite and lesser galena, chalcopyrite and sphalerite; float samples assayed up to 122 grams per tonne gold and 70 grams per tonne silver (Assessment Report 13580).

In 1992 Noranda carried out 1:5,000 scale geological and alteration mapping and in 1993, they drilled 6 reverse circulation holes on the Kliyul skarn zone (Assessment Report 23033) and followed up with an airborne magnetic, EM, and radiometric survey (Assessment Report 23379). This airborne survey also covered (or nearly covered) 25 MINFILE occurrences including the Denum (094D 142) occurrence which is just northeast of the survey boundary.
