The Delphi showings are located just south of the 49th parallel on Vaughn Creek approximately 8.5 kilometres north of Cowichan Lake.

A series of subparallel, steeply dipping quartz-calcite veins crosscut pyroxene phyric tuffs and breccias of the Middle Devonian Nitinat Formation (Sicker Group). The veins are probably genetically related to the Delphi Lake stock, 300 metres to the south, which is probably related to the Early to Middle Jurassic Island Plutonic Suite. The area has undergone regional greenschist metamorphism.

Mineralization consists of disseminated pyrite, chalcopyrite and pyrrhotite in veins and pods of magnetite in epidote-rich, skarn-like rocks. A sample of pyritized quartz from the dump on the Iron Crown claim assayed trace gold and 1 per cent copper (Minister of Mines Annual Report 1930, page 303). The veins are up to 15.2 metres long and are generally less than 23 centimetres wide. A vein on the Brass claim strikes 005 degrees and dips 80 degrees east.

The workings consist of a 2.5 metre shaft on the Brass claim (Lot 78), a 10 metre shaft on the Iron Crown claim (Lot 79) and a short adit on the Tyro claim (Lot 77), collectively known as the Delphi or Jubilee property. The claims were first staked in 1900. In 1976, Echo Minerals completed a program of silt sampling on the area as the Skyline claims. In 1978, E. Specogna completed a program of prospecting on the area as the Close, Amore and Dibenedetto claims. In 1979, the claims were acquired by Aquarius Resources and a program of one diamond drill hole, totalling 10.9 metres, was completed near Summit Lake. A program of rock and soil geochemical sampling was completed the following year.
