The Heber 1 occurrence is located on an east facing slope, approximately 250 metres west of the Heber River and 12 kilometres northeast of the town of Gold River.
The area is underlain by massive green porphyritic basalt of the Upper Triassic Karmutsen Formation (Vancouver Group). A stock of the Early to Middle Jurassic Island Plutonic Suite disrupts the strata to the immediate northwest of the showing.
Locally, basalt and andesite host a 1 metre wide mineralized quartz vein that has been mapped over a distance of 1.6 kilometres. Sulphide mineralization is assumed to include pyrite and chalcopyrite. Rock sampling, in 1970, is reported to have yielded values up to 10.85 per cent copper, 42.9 grams per tonne silver and 12.0 grams per tonne gold over 1 metre (Assessment Report 14551).
In 1970, Silver Standard completed a program of prospecting and rock sampling on the area. In 1984, J. McDonald prospected the area as the Heb claims. In 1994 and 1995, Orvana Minerals completed programs of geological mapping and geochemical sampling on the area as the Heber claims. In 2011, Universal Ventures Inc. completed a program of geochemical sampling, geological mapping and an airborne geophysical survey on the area as the Tib claims, Tibor property.
In 2018 an interpretive study was conducted on the Trio property by tenure holder K. Galambos. The study included air photo and geophysical interpretation as well as historical research and limited prospecting on the area surrounding Trio Mountain (Assessment Report 38109).
