The Log 1 occurrence is 0.9 to 1.5 kilometres northwest of Hook Lake and approximately 3 kilometres southwest of the north end of Missezula Lake.
The region west of Missezula Lake is underlain by the eastern volcanic facies of the Upper Triassic Nicola Group, comprising mafic to intermediate augite and hornblende porphyritic pyroclastics and flows, and associated alkaline intrusions. The intrusions vary in composition from diorite to monzonite and are thought to be comagmatic with the Nicola Group, ranging in age from Upper Triassic to Lower Jurassic. Much of the copper mineralization and associated alteration frequenting this portion of the Nicola Belt can be attributed to the emplacement of such intrusions.
Locally, several occurrences of chalcopyrite, chalcocite and malachite are hosted in augite plagioclase porphyritic andesite and volcanic breccia of the Upper Triassic Nicola Group (Central Belt, Bulletin 69). The mineralized outcrops occur over a north-south distance of 600 metres.
In 1978, a chip sample on an occurrence of chalcocite and malachite in a highly fractured and chloritized basalt associated with a west-northwest–trending fault zone assayed 0.7 per cent copper over 2 metres (Assessment Report 7165).
In 1985, a sample (2096), taken from the vicinity of the previous sample, assayed 0.263 per cent copper and 1.9 grams per tonne silver (Assessment Report 14141, Figure 9).
Work History
In 1977, Quintana Minerals Corp. completed a program of prospecting, geochemical sampling and a 32.0 line-kilometre ground magnetic survey on the area immediately west of the occurrence as the Homestead claims. In 1978 and 1979, Cominco Ltd. completed programs of geological mapping, geochemical (rock and soil) sampling and approximately 9.4 line-kilometres ground magnetic and induced polarization surveys on the area as the Thalia claims.
In 1985, Vanco Explorations Ltd. completed a program of geological mapping and geochemical (rock and soil) sampling on the area as the Bloo, Climax and Thor claims. In 1987, a further program of rock and soil sampling was completed on the claims. Also in 1987, Cominco Ltd. completed a program of soil sampling on the area as the Log 1-4 claims.
In 1991, Rayrock Yellowknife Resources Inc. and MineQuest Exploration Associated Ltd. completed nine rotary drill holes, totalling 650.7 metres, on the area as the Zul 1-2 and Zig 1-6 claims.
In 2004, Copper Hill Exploration Corp. completed a program of geological mapping and photogeological interpretation on the area as the Ketchan property. In 2005, Copper Belt Resources Ltd. completed a program of geological mapping and 13.0 line-kilometres of ground magnetic and electromagnetic surveys on the area as the Central Nicola property.
In 2011, Moag Copper Gold Resources Inc. completed a program of soil sampling on the area as part of the Ketchan property. In 2013, West Cirque Resources Ltd. completed a program of geological mapping and rock sampling on the area as the Aspen Grove property. During 2014 through 2016, KZD Aspen Grove Holding Ltd. and Kaizen Discovery Inc. completed programs of prospecting and geological mapping on the Aspen Grove property.
