The Princess occurrence is located on Manson Island, approximately 11 kilometres east-northeast of the community of Beaver Cove.

The area lies at the eastern margin of the Insular tectonic belt near its contact with the Coast Crystalline Belt.

The occurrence is underlain by massive andesitic and basaltic lavas of the Upper Triassic Vancouver Group, Karmutsen Formation. The volcanics have undergone regional epidote alteration.

Mineralization consists of chalcopyrite, with minor bornite, native copper and pyrite, occurring in association with a quartz- filled shear zone. In one section massive chalcopyrite occurs over a width of 30 centimetres. Mineralization also occurs as fracture fillings, amygdaloidal coatings and disseminations.

Fractures show epidote, quartz, calcite, chlorite and zeolite alteration.

The Princess group of three mineral claims was located about 1900 by Raper, Law, and Hamilton. By 1916 a shaft was sunk at the beach, a 150-metre north-south adit was driven along a fracture plane, and at 38 metres elevation, a 49-metre shaft was sunk which connected to the adit. Ore was shipped in 1916, but no production figures are available. In 1971 Croydon Mines Limited held the Haw 1 to 3 claims and carried out a geochemical soil survey. In May 1973 the Company became Aalenian Resources Limited. In 1983 and 1984, Malka Resources Ltd. completed programs of geological mapping, geochemical surveys and magnetometer and VLF-EM surveys.

Limited 1983 grab sampling from the adit ore dump returned values between 7.3 and 41.2 per cent copper, 6.5 to 23.0 grams per tonne silver, and very low lead, zinc and gold values (Assessment Report 12639).
