The area of the Victory-Triumph occurrence is underlain by the southern contact of the Middle Eocene Coryell batholith with the Upper Cretaceous Sophie Mountain Formation. The Coryell Intrusions are generally coarse-grained and range in composition from syenite to monzonite and granite. The Sophie Mountain Formation comprises conglomerate with thin interbeds of argillite and siltstone.

By 1887, a vein or ore mass, showing rich copper ore, had been exposed by stripping for 18 metres and "defined for 6 metres between walls at another point". Samples from a 3.7-metre deep shaft gave assays of: 15.3 per cent copper with a trace of gold, on surface; 22.1 per cent copper with 5.35 grams per tonne gold, at 1.2 metres depth; and 30.4 per cent copper with 5.02 grams per tonne gold, at 2.4 metres (Hodges, 1897). The country rock is stained with malachite and assays 9.7 per cent copper. An adit has also been driven and was in 38 metres by the year 1897.

In 2006, Major Gold Limited conducted a mineral exploration program on the Portland Project. This included prospecting, grid surveys, soil geochemistry, rock sampling, and magnetometer surveys. Results from the soil grid geochemistry survey and the magnetometer survey showed anomalous gold, silver, copper, arsenic, lead, and zinc patterns correlating to known mineralization on the property. At Victory-Triumph specifically, arsenic, gold, copper, and zinc are found in the southern portion of the survey grid with a lead and zinc anomaly displaying a 100 metre by 200 metre area open to the southeast.
