The Borg occurrence area is underlain by two ages of intrusive; Middle to Late Triassic foliated diorite to quartz monzonite and Tertiary monzonite related to the Sloko-Hyder Plutonic Suite. The younger monzonite is locally silicified and/or pyritized. Feldspar +/- quartz porphyry dikes are also related to the Sloko-Hyder suite and cut the other intrusive rocks along a northwesterly - north-northeasterly trend. Late (Tertiary) mafic dikes follow the same structural orientation as the felsic assemblages.
Four types of mineralization were noted on the claims. These include: altered monzonite hosting disseminated pyrite, chalcopyrite, malachite, sphalerite +/- galena; quartz veining developed marginal to northwest - north-northeasterly trending mafic dykes; quartz veins cutting fresh to altered diorite; and quartz veining stockwork quartz breccia associated with felsic dykes.
Spatially, the bulk of the intrusive hosted mineralization that was sampled is associated with the younger monzonite in the northern portion of the claims (Green and Black claims). Here the monzonite is locally silicified and pyritized. Mineralization consists locally of up to 10 per cent galena + pyrite with lesser sphalerite and chalcopyrite. Samples of this type of mineralization returned analyses to 2.19 grams per tonne gold and 15.8 grams per tonne silver (#18525), 0.5 per cent copper (#18080), 1.0 per cent lead (#18571) and 1.2 per cent zinc (#18946) (Assessment Report 22268).
Locally, quartz veining, quartz stockwork and quartz breccia occur marginal to mafic and/or felsic dyking. Those associated with felsic dykes have returned values to 3.3 gram per tonne gold (# 18947) and 6.4 grams per tonne silver (# 18170) with low base metals. Veining developed marginal to mafic dykes contains lower precious metal values (0.19 gram per tonne gold (#18083) and 14.1 grams per tonne silver (#18167), but higher base metals (0.14 per cent copper (#18083), 1.7 per cent lead (#18040) and 2.6 per cent zinc (#18084)).
In 1991, International Suneva Resources Ltd conducted field work consisting of contour soil/talus-fine sampling (approximately 4.2 km of line; 85 samples), 1: 5,000 scale mapping and prospecting. During mapping, samples of altered and mineralized float and outcrop were routinely taken (47 samples) (Assessment Report 22268). No other previous work is recorded for this area.
In 2017, In the summer of 2017 the field crews investigated areas of interest outside of the main Metla Creek corridor as well as outcrop newly revealed by the retreating glacier. A ground magnetic survey was also conducted over the main zone of interest. Rock and soil sampling (89 rock and 9 soil) returned significantly anomalous results. Eight samples were collected at the Borge showing.
In 2018, Stuhini Exploration Ltd. contracted Geotech Ltd. to conduct A VTEM (versatile time-domain electromagnetic) airborne survey. The survey covered 419 line kilometres over the entire Metla property. The 2018 VTEM survey covered the entire property at 250 metres spacing and the Metla Creek Area at a detailed 100 metres spacing. The Borge (104K 160), Metla (104K 161) and Clive (104K 173 held as part of the Metla and were covered by the survey. The survey revealed conductive anomalies and proximal magnetic lows paralleling the surface trace of the Metla Creek Structure.
In 2020, Brixton Metals Corporation completed a program of geochemical (rock and soil) sampling, a 12.5 line-kilometre ground induced polarization survey, a 715 line-kilometre airborne magnetic and electromagnetic survey and 19 diamond drill holes, totalling 5292 metres, on the area of as part of the Thorn property. Drilling was performed on the Outlaw (MINFILE 104K 176) occurrence area.
