The Consortium Project has no known history for mining and has remained relatively undeveloped possibly as a result of its isolated location and moderate to high elevation. Logging activity has occurred since the 1920s in the White River Valley at the north end of the Property, but the southern parts are in a moderate elevation valley that is enclosed by subalpine to alpine barriers that the logging road system is only just accessing now via Consort Creek, the drainage route from Stewart Lake.
The first exploration indicators of mineralization in the area may have been the anomalous stream geochemical concentrations of gold and copper published in a provincial Regional Geochemical Survey (RGS) in 1989 (Matysek et al. 1989). These results included high values of gold, mercury and silver and prompted staking of the SORT 1 – 7 claims (the first known recorded claims) and 68 man-days of detailed exploration work by Arne Birkeland in 1990 (Birkeland, 1991). Arne Birkeland’s exploration work is well documented in Birkeland’s 1991 report, which provides a thorough description of the geological setting and mineralization, but predates access to Global Positioning System so some sample locations are approximate. Subsequent recorded work on the Property included exploration by Greig (2008) involving silt and soil geochemistry and Schuss (2013) involving a minor program of soil and rock geochemistry. Parts of the claim area were staked by Benjamin Mossman in 2006 and 2011, but in each case were allowed to lapse without any record of technical work. A detailed history of the spatial extent and dates of the various claims staked between 2005 and the present is available in the Mineral Titles Online website.
Birkeland (1991) discovered mineralized outcrops indicated by Au, Ag, Cu, Zn, Ba, As, Hg, and Sb stream silt geochemical anomalies and float prospecting in two creeks, named A-1 Creek and 1324 Creek in the center of the current Property. Float samples, although not replicated in outcrop show some high precious metal grades: sample AB-100 assayed 70 g/t Au, 545 g/t Ag, and 12% Cu and AB-101 101 g/t Au, 423 g/t Ag and 2.6% Cu. Mineralization, discovered upstream of the float samples in A-1 Creek, is the most extensive and is described as consisting of gold and silver-rich quartz-ankerite veins with polymetallic sulphides including chalcopyrite, sphalerite and galena. Associated arsenopyrite and stibnite were observed disseminated in host rocks. The mineralized occurrences are structurally and spatially related to steeply dipping northeasterly to easterly trending faults that are the locus of cleft and small creeks. The main type of sulphide mineralized occurrence observed by Birkeland (1991) consisted of crosscutting quartz-carbonate veins and breccias with pervasive proximal silicification of host rocks and peripheral epidote chlorite alteration. Five channel samples (all less than one meter in true width) taken over a 450 meter length of the A-1 Creek occurrence range in grade from 5 to 33 g/t gold, 5 to 96 g/t silver and 0.14 to 0.86% copper and 0.37% to 8.42% zinc. Birkeland reported a weighted average for samples AB-120 and AB-121, representing the widest mineralized zone over a true width of 1.5 meters, of 9.5 g/t Au, 8.3 g/t Ag, 0.57% Cu and 5.7% Zn (Birkeland, 1991).
A disseminated style of sulphide mineralization was also observed as pyritic “stringer zones and crudely banded sulphides” (Birkeland, 1991) in volcanic flows displaying bleaching, interpreted as albitization, of epidote-chlorite assemblages. Birkeland suggested and average or representative grade from one sample (AB-87 #26310) which assayed 4.36 g/t Au.
In 1324 Creek, mineralized float was reported by Birkeland (1991) along 300m of the fault zone. Mineralization is described as cross-cutting quartz veins and sulphide rich altered volcanic rocks. Sample AB-109 (#26332), assayed at 0.5% Cu and 88 g/t Ag was obtained over a 1 meter true width channel sample with related arsenopyrite and stibnite.
