The Still area is underlain by the northeast trending contact of the Upper Triassic Stuhini Group on the north and the Upper Paleozoic Stikine Assemblage on the south.

The volcanic and sedimentary sequences are intruded by the Tertiary-Cretaceous Coast Plutonic Complex. A wide variety of intrusive phases are present including granodiorite, quartz monzonite and diorite.

The Still occurrence is underlain by argillite, greywacke and siltstone. A chip sample was taken across a 30.0 centimetre wide quartz vein mineralized with pyrite, pyrrhotite, galena and sphalerite. The sample assayed 29.42 grams per tonne gold, 13.7 grams per tonne silver, 0.83 per cent lead and 0.36 per cent zinc (Vancouver Stockwatch, October 14, 1988).

In 1987, Zara Gold Syndicate collected 3 heavy mineral samples and 22 rock samples from the Secretariat and Still claim. Float samples collected from the claims returned anomalous values of 15.39 grams per tonne gold and 18.24 grams per tonne gold (Assessment Report 17279). It is possible that follow-up work in 1988 gave rise to the Vancouver Stockwatch report (October 14, 1988) of the 30 cm chip sample containing 29.42 grams per tonne gold. In 1994, Ashworth Explorations limited carried out a field program consisting of geological mapping, rock and stream silt sampling on the Halo-Danzig claims for Guardian Resource Corporation. Twenty-seven rock samples were collected at this time. The results of the work failed to indicate any significant mineralization on the property.
