The Princess area is underlain by Jurassic Telkwa Formation (Hazelton Group) volcanics that have been intruded by Late Cretaceous Bulkley and Early Jurassic Topley plutonic suites. In the vicinity of the occurrence, the rocks are mainly andesitic flows and pyroclastic strata of the Hazelton Group which have been cut by numerous basic and acid dikes. The volcanics are generally strongly chlorite and epidote altered.
The Princess showing occurs in highly sheared and epidotized fine-grained, greenish volcanics. Mineralization consists of several narrow shears and veinlets of hematite, iron-rich sphalerite and chalcopyrite in a gangue of white calcite and quartz.
A sample was taken in 2008 at the Princess showing from a quartz-carbonate vein cutting garnet-epidote-diopside skarn with chalcopyrite and sphalerite yielded 0.71 per cent copper with 9.7 per cent zinc (Assessment Report 31515).
The 2008 El Toro program of Lions Gate Energy Inc involved mapping, prospecting, 87 rock and 15 soil geochemical samples, GPS surveying of previous diamond drill hole collars, and underground and surface workings, an evaluation of the property (Assessment Report 30731), followed by a 1495 line kilometre airborne magnetic and electromagnetic geophysical survey (Assessment Report 30982). The survey on the West block covered Princess (093L 061), War Eagle (093L 062), Evening (093L 064), Duchess (093L 066), Countess (093L 067), MSJ (093L 241), Ant 1 (093L 320).
See Duchess (093L 066) for details of the work history of the Howson Basin showings which include Princess (093L 061), War Eagle (093L 062), (Evening (093L 064), Silver Heels (093L 065), (Duchess (093L 066), Countess (093L 067), Tom ((093L 068) and Starr (093L 069).
Refer also to King (093L 041) for general information on the El Toro property, a large property that was worked by Lions Gate Energy Inc from 2007 to present (2015) and encompassed a very large area including the Tommy Houston Creek area.
