The Eighty occurrences consist of three nearby showings called occurrences 10, 19 and 25. The area is underlain by sedimentary and volcanic rocks of the Upper Triassic Stuhini Group.

Occurrence 10 was first reported by Continental Gold Corp in 1988. It consisted of a 10 to 25 centimetre wide shear zone with galena, chalcopyrite and possibly tetrahedrite. A sample of this shear zone graded 4.22 grams per tonne gold, 9.78 per cent lead, and 2.48 per cent zinc (Assessment Report 18555 and 21061).

Occurrence 25 was located in the Occurrence 10 area in 1990 by Gigi Resources. The showing consists of a 20 metre long massive sulphide vein that varies in width from 0.6 to 1.5 metres. Grab sampling of this pyrrhotite-pyrite-chalcopyrite vein yielded up to 0.25 gram per tonne gold and 0.24 per cent copper (Assessment Report 21061).

A two centimetre wide oxidized vein within augite porphyry is located approximately 230 metres southeast of this massive sulphide vein of Occurrence 25. In 1990, a select sample of this vein (32293), which is exposed for 15 metres, assayed 1.23 grams per tonne gold with 0.35 per cent copper (Assessment Report 21061). Sample 32294, taken from a subcrop of Stuhini lapilli tuff with disseminated pyrrhotite and a small seam of pyrite located 35 metres southwest of sample 32293 assayed 1.75 grams per tonne gold (Assessment Report 21061). The slope from which these samples were taken is underlain by a package of Stuhini sediments, volcaniclastics, and flows, which are locally hornfelsed by a biotite lamprophyre dike. The source of bleached, silicic, pyritic float, which assayed 23.2 grams per tonne gold (Occurrence 19) could not be located.
