Capsule Geology

The Troy occurrence lies along a north-northwest trending contact between sediments and volcanics and epiclastics, all of the Jurassic Hazelton Group. The rocks to the east consist of argillite and interbedded siltstone, sandstone and conglomerate of the Middle Jurassic Salmon River Formation. These are underlain, from east to west, by tuffs of the Mount Dilworth Formation, epiclastics of the Betty Creek Formation, and andesite and andesite tuff of the Unuk River Formation, all Lower Jurassic in age. The rocks are cut by Tertiary lamprophyre and microdiorite dykes.

Several quartz veins and altered zones occur over a 1200 by 900 metre area. A set of veins, striking 160 degrees and dipping 45 to 80 degrees northeast, occur along the argillite-andesite contact and within the argillite. Mineralization in the veins, which average about 10 metres wide and about 700 metres long, consists of galena, sphalerite, tetrahedrite, chalcopyrite and minor freibergite, argentite, native silver and pyrargyrite (ruby silver). A 76 centimetre sample of one of the veins assayed 1220 grams per tonne silver and 43.5 per cent lead (Annual Report 1924). Map 3-2055 indicates the location of the "argillite-andesite" contact with vein also indicated (Appendix, Assessment Report 23220). Mitchell (1937) also reports that on the Troy claim at the north end of the ground, a quartz vein showing galena was sampled across 0.6 metres and assayed trace gold and 6.86 grams per tonne silver (Appendix, Assessment Report 23220).

Within the volcanics are silicified and pyritized zones containing disseminated pyrite and erratic occurrences of galena and sphalerite. Scheelite may occur within quartz veins in the andesites, as a 15 centimetre sample assayed 3.0 per cent tungsten, with 13 grams per tonne silver and 0.7 grams per tonne gold (Property File Map, 1937).

Work History

The Troy group of claims extends from Daisy Lake, a small lake near the southeast corner of Summit Lake, southeastward to about the 1890 metre elevation. The Daisy group of claims covers Daisy Lake and extends northwest to the shore of Summit Lake. The Troy group of 9 claims, including the Troy Nos. 2 & 3, Butte, Welcome, Deadwood, L.X., Reward, and Terry claims, was located in 1919 by Neil McDonald. Mr. C.H. Lake purchased a 1/3 interest in the property in 1923. In the fall of 1924 E.O. Weston, of Victoria, bonded the property and Northland Mining Company, Limited was formed in January 1925 to develop the showings. A limited amount of work, mainly open cutting and surface exploration and about 213 metres of diamond drilling was done by the company before the option was dropped in October 1926. The owners resumed work on the property and by additional staking increased their holdings to 23 claims. The showings have been prospected by a large number of open cuts and by two short adits, one on the Troy No. 3 claim was driven 15.2 metres, the other, on the Troy No. 2 claim, was driven 4.6 metres. Work in 1938 by a Mister McDonald and a Mister Lake was reported.

The Daisy group of 7 claims, including the Daisy Nos. 1 & 2, and the Summit Nos. 1-3 was located in about 1924 by H.F. and S.G. Benson of Victoria. Salmon River High Grades Company was formed in 1925 to promote the property. The only development work reported was a small amount of trenching. The company charter was surrendered in 1931. In 1965 the property consisted of one located claim held by H. swan, of Stewart. The above claims lapsed at some time prior to the 1989.

A new Troy claim was staked by D. Johnson in 1989 and obtained by David Javorsky 1991. This claim was 1 kilometre long (north-south) and 500 metres wide. It extended north from the northern corner of the Dickens reverted Crown-grant claim (Lot 4030) which is immediately east of the new MINFILE showing Harry (104B 434). The 1993 report by Javorsky (Assessment Report 23220) contains a 6-page report by J.A Mitchell of the Premier Gold Mining Company dated 1937. The accompanying map (3-2055), also contained in the Javorsky report, shows the original group of claims from the 1910s and 1920s that existed in the area between the Dickens Crown-grant and Summit Lake, including the lapsed Troy 1-11, Butte, Welcome, Deadwood, L.X., Reward, and Terry claims.
