The Brenda occurrence is located by a small lake (Moon Lake) near Mount Leonard, about 21 kilometres northeast of the community of Atlin.
The area is underlain by the Middle Jurassic Fourth of July Creek batholith (Three Sisters Plutonic Suite) which is a zoned, probably multiphase intrusion composed mainly of granodiorite, quartz monzonite and quartz diorite. The rocks display a relatively wide range of textural features, but medium and coarse crystalline textures prevail.
The Brenda showing was accessed historically by two adits, each surrounded by tailing dumps of considerable size. The adits have not been rehabilitated and their lengths or geological settings are not known. The adits, at present not accessible, tested the Brenda zone at two different elevations. Two outcrops of the same zone aligned with both adits are situated at higher elevations up to Moon Lake.
The Brenda zone includes a mineralized structure (structures?) with estimated widths of up to 1.5 to 2.0 metres and can be locally traced for approximately 450 metres along its strike. The zone strikes northeast and dips at an angle of 60-65 degrees towards the southeast. Mineralization consists of galena, sphalerite, and minor pyrite and barite. Pervasive chlorite-epidote alteration is frequently accompanied by strong silicification and carbonatization. Strong manganese-iron staining is typical along fractures. The mineralization is apparently associated with contacts between a thick quartz feldspar porphyry dike and some fine-grained mafic dikes, with diorite. In 2007, grab samples assayed up to 1109 grams per tonne silver and 1.58 per cent zinc. Sample BW-L2+200N returned 1109 grams per tonne silver and 0.06 per cent zinc (Assessment Report 30390).
In late 2006, Saturn Minerals Inc. optioned the Wheelbarrow property and became the operator. During the early summer of 2007, Saturn Minerals conducted prospecting and rock sampling programs accompanied by lithological and structural observations. A total of 420 samples (including 98 chip samples taken from hand-trenched mineralized zones) were collected and analyzed. The rock sampling program was designed to test the character and grade of mineralization in several known showings and sites, as well as to prospect for extensions of the known zones and for completely new zones. The purpose of this extensive sampling program was also to select targets for subsequent mechanical trenching and, eventually, diamond drilling programs, both of which took place later on during the same field season. During mid- to late- summer 2007, Saturn conducted complementary soil, trenching and drilling programs. The soil sampling resulted in 74 soil samples taken in four distinct areas of the property. Excavator trenching resulted in 16 trenches and test pits totalling 315 metres in length. Approximately 150 rock samples from the trenches were sent for analysis. Nine diamond-drill holes were drilled to test the southern Big Canyon (104N 011, 144) mineralized structure. The total length of the drillholes was 607.68 metres; 255 core samples were sent for analysis.
Global Drilling Solutions Inc. acquired the majority of the claims comprising the current Ruby Creek Project in the spring of 2016 from Adanac Moly Corporation. For the 2016 field season Global chose to target gold vein deposits structurally controlled by faulting within existing placer creeks with the main focus on Boulder Creek. In 2017, Global conducted geochemical sampling, drilling and ground geophysics on the Ruby Creek property. Rock sample 1532950, which is located in the vicinity of the Brenda occurrence, returned 5.4 per cent lead, 1 per cent zinc, 0.04 per cent copper, 570 grams per tonne silver and 0.1 gram per tonne gold (Assessment Report 37171). In 2018, Global carried out further geochemical sampling and drilling on this property. It’s mentioned that the Ruby Creek property remains of high interest for not only gold/molybdenum but also for silver and copper based on the exploration work during during 2017/2018 (Assessment Report 38256).
In 2020, Stuhini Exploration conducted mapping, prospection, ground geophysics and geochemical sampling on the Ruby Creek property. Rock sample 1996068, which was collected within approximately 500 metres of the Brenda occurrence, returned 109 grams per tonne silver (Assessment Report 39374). In 2021, an airborne SkyTEM survey was conducted by Stuhini on the Ruby Creek property, which revealed a number of regional trends across the property.
