The Debeaux Creek showing is located about 2.5 kilometres west of Peak Lake.

The area is underlain by rocks of the Paleozoic Sicker Group comprising deformed breccia, tuff, argillite, greenstone, greenschist, narrow dykes of andesite porphyry, and argillaceous and calcareous sedimentary rocks. There are numerous faults and shear zones in the area suggesting a north-northeast fault through the Peak Lake area. A number of quartz veins and carbonatized zones are present.

The Debeaux Creek zone is characterized by locally intensely carbonatized basaltic and andesitic volcaniclastic rocks of the Devonian Duck Lake Formation and extensively serpentinized diabasic gabbro. These are likely related to the northeast trending faults which transect the area. A Late Triassic(?) diabasic gabbro of unknown affinity has intruded along the Debeaux Creek fault. Later stage movement along the fault combined with hydrothermal processes has altered portions of the gabbro to magnetite-rich serpentinite with associated nickel-bearing sulphide mineralization. The zone of serpentinization is up to 300 metres wide with an undetermined strike length. This zone bears certain similarities to a magmatogenic deposit, in that the gold is associated with nickel-sulphide segregations in ultramafic to mafic rocks.

From 1983 through 1989, Au Resources Ltd. completed programs of prospecting, geochemical sampling, geological mapping, trenching, an induced polarization survey and twelve diamond drill holes, totalling 1511.8 metres, on the Emma claims. A grab sample (16232) assayed 0.0382 per cent nickel and 0.913 per cent chromium (Assessment Report 17207). A sample from a 5 centimetre quartz-carbonate vein containing pyrite and pyrrhotite and cutting basalt near the serpentinite contact assayed 0.20 grams per tonne gold (Assessment Report 17207).
