Mineralization at the Evening consists mainly of chalcopyrite, pyrite, galena and hematite and is associated with narrow irregular shears in highly epidotized and chloritized fine-grained andesitic tuffs and/or flows of the Lower Jurassic Telkwa Formation, Hazelton Group. In at least one case, the shear is adjacent to and within a diabase dike. The mineralized shears trend northeast to east and dip moderately north.
A sample taken in 1991 assayed 1.9 per cent copper from the Evening (Assessment Report 21722).
WORK HISTORY
The Evening claim (Lot 1816 R.5) was located in about 1905 by Harry Howson for W.D. Lukeas, of Chicago. Telkwa Mining, Milling and Development Company was incorporated in Seattle and registered in British Columbia in 1906. The Evening and some 40 other claims in "Howson Basin" were Crown-granted to the company in 1911. Work on the Evening claim included trenching which traced the vein for a length of 457 metres, and 21 metres of drifting in one adit. The company registration was surrendered in 1924.
Norcan Mines Ltd in 1966 acquired the Evening property as part of a group of 255 claims covering Howson Basin. Work during the year included geological mapping, geophysical surveys, and hand trenching on the Evening showing.
Bethex Explorations Ltd. optioned the Norcan Mines property in November 1966 and during 1967 and 1968 carried out geophysical and geochemical surveys, and trenching; the option was subsequently given up.
Through an August 1970 agreement and subsequent exploration work Pathfinder Resources Ltd. acquired from Norcan Mines an undivided 50 per cent interest in the property. The company name (Norcan) was changed in 1972 to Accent Resources Ltd.
In 1991, minor sampling and examination of Duchess and Evening adits by Skeena Resources Ltd occurred, with the best sample yielding yielded 9 per cent copper and 88 grams per tonne silver over 1 metre on the Duchess and 1.9 per cent copper from the Evening (Assessment Report 21722.).
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).
