The Delos/Trojan is located at 1830 metres elevation on the west side of Bruce Creek, a tributary of Horsethief Creek some 18 kilometres west of Invermere.

The Delos group, comprising the Delos, Calamity Jane and Trojan claims, and across the creek the Colossus claim, were owned by Tom Jones of Golden. He optioned them in 1898 to The Mines Development Trust and Gaurantee Company, Limited. Development work encompassed open cuts and a 16-metre crosscut adit and drift.

No further activity was reported until the Delos and Calamity Jane were Crown-granted to E.J. Scovil of Golden in 1916. The Trojan claim was Crown-granted to W.R. Grubbe that same year. The Property was acquired in 1918 as the Trojan group (6 claims) by F.W. Wonn, who formed the Trojan Copper Mines Corporation, of Seattle. Work during 1918-19 was done in open cuts and in a 35 metre adit. Government records show that 40 tonnes of ore were mined in 1919, from which 218 grams of silver and 4191 kilograms of copper were recovered.

In 1972, G.B. Allan acquired these grants and those of the Pretty Girl group (082KNE025). Some work was reported to have been done (Assessment Report 20887). In 1981, the showings were re-examined on behalf of owners D.J. Gallagher and R.W. Pearson and several grab samples were collected.

By 1988, nine reverted Crown Grants of the Pretty Girl and Delos/Trojan groups were owned by Clive Ashworth as recorded in 1986. These were subsequently optioned to Gold Ford Capital Corp. In 1988, Ashworth Exploration, on behalf of Gold Corp Captial Corp, constructed a survey grid on the Delos/Trojan claims.

In 1995 W. Pochylko had a 20-kilometre self-potential survey completed on his Jay claims which cover the Delos/Trojan and Pretty Girl workings as well as other workings to the south. In 1996, W. Pochylko completed a 6.4-kilometre self-potential survey in the same areas.

The Delos/Trojan area is underlain by upper Proterozoic coarse clastic sedimentary rocks of the Horsethief Creek Group. The rock in the mineralized area is reported to be schistose slate with the foliation dipping nearly vertically. The strike is irregular but averages 300 degrees. An irregular quartz vein that splits into stringer, occurs along the foliation. The vein attains a width of up to 1.5 metres locally. The quartz is well-mineralized with chalcopyrite with solid bunches occurring locally. A sample across 1 metre from one open cut yielded 0.69 gram per tonne gold, 27.43 grams per tonne silver and 9.6 per cent copper (Annual Report 1915, page 96).
