The LLK occurrence is underlain by undifferentiated volcanic and sedimentary rocks of the Upper Triassic Stuhini Group. The dominant rock type is a deformed, faulted and altered andesite, which is intruded within a few kilometres of the occurrence by a Middle Jurassic(?) granitic stock. Tabular to irregular masses of syenite and rhyolite intrude the andesite and the granitic stock. These exhibit similar deformation and alteration as the enclosing andesites.
The andesite is irregularly but pervasively altered by propylitization, producing zones of epidote and saussurite. Epidote is abundant as veins and fracture fillings, and is sometimes associated with white quartz.
Diffused pyrite in small irregular patches is common, and can form dark red gossans in andesite. Several major gossans in the area are related to greater concentration of copper minerals which occur as malachite and azurite with minor chalcopyrite and chalcocite. One of the "iron sulphide-andesite bodies shown on Map 1 of Assessment Report 3029 is up to 350 metres by 1400 metres in area. These minerals occur as tabular bodies, thin fracture fillings, and discontinuous veins up to 60 centimetres wide and 30 metres long.These veins are steeply dipping and have pronounced north and east trends. Molybdenite was also found in quartz veins about 5 centimetres wide and traceable for a few metres.
A chip sample reported to have been taken on the LLK-DOK claims across 1.2 metres contained 11.3 per cent copper, 120 grams per tonne silver, 0.34 grams per tonne gold, and a trace of molybdenite (Assessment Report 3846). The exact location was not given.
In 2008, 138 soil samples, focused on the Krego Zone (to the north of the DOK (Main Showing) and on the area immediately south of Red Creek, was combined with previous historic soil geochemical sampling in the area, showing copper, gold, silver and molybdenum values (Figures 26-29); figures 30 and 31 show the contoured soil geochemistry for copper and gold (Figures 26-29, Assessment Report 30706). Mineralization at DOK (104G 043), and the soil anomaly immediately west and north of LLC that stretches north to Daon (104G 238) and Himiomo (104G 191), is thought to be genetically-related to the emplacement of syenite intrusions, as the northerly-trending soil anomalies appear to parallel the trend of the intrusions.
Between 2011 and 2016 Brades (BRC) collected a total of 205 soil samples from three separate areas within the DOKX Property (referred to as the West Boundary Grid, the East Boundary Grid and the Doc 35 Grid) The East Boundary soil grid occurs just west of the LLK MINFILE plot (Figure 8, Assessment Report 35278, 36987).
