The Midway showing is underlain by Devonian sedimentary and volcanic rocks of the Stikine Assemblage. The Devonian Forrest Kerr Pluton is in contact to the immediate west of the Stikine package. Plutonic rocks consist primarily of Late Devonian granite and diorite.
The Midway showing area was first described in 1988 as a series of weakly mineralized quartz veins containing minor amounts of chalcopyrite and malachite. In 1990, a soil sampling program was initiated by Avondale Resource that covered a portion of the showing. Anomalous soil results were yielded including a gold value of 8.8 grams per tonne gold (Assessment Report 20562). Follow up prospecting in the general area led to the discovery of gold bearing, chalcopyrite-malachite quartz breccia talus float. Sample 39152 assayed 15.0 grams per tonne gold and 1.7 per cent copper (Assessment Report 20562). Further prospecting failed to turn up in situ mineralization while later detailed soil geochemistry outlined a 400 metre long multi-element soil anomaly, itself spatially related to a major northeast trending structural lineament.
