The Heber occurrence is located on a southern slope of Trio Mountain, approximately 2.5 kilometres west of the Heber River and 11.5 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). These have been intruded by a stock of the Early to Middle Jurassic Island Plutonic Suite.

Locally, a fine-grained andesite hosts a vuggy and rusty pyritic stock work zone. In 1994, a sample (209335) assayed 1.06 grams per tonne gold, 2.9 grams per tonne silver and 0.53 per cent copper (Assessment Report 23547). In 1995, rock sampling yielded 0.6 per cent copper, 9.2 grams per tonne silver and 0.54 gram per tonne gold over 50 metres (Assessment Report 24090).

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).
