A short, 7-day reconnaissance exploration program conducted in the summer of 2020 is the only known modern gold exploration to occur on the property to date. The prospecting and ridge-and-spur soil sampling program resulted in the collection of 185 soil samples and 94 rock grab samples. The program was successful in discovering widespread high-grade gold in rock grab samples over 6 kilometres with assays up to 164 g/t Au and 257 g/t Ag. The mineralization discovered to date shares characteristics of both Cu-Au porphyry and intrusion-related gold deposits.
A few different styles of mineralization occur at the Willie Jack property with the dominant style consisting of copper sulphides and oxides (chalcopyrite, malachite, bornite, azurite) and variable amounts of galena (lead sulphide) and pyrite in narrow steeply dipping quartz veins hosted in the granodiorite pluton. These veins carry the highest gold and silver grades on the property. Bedrock samples of veining have returned assays up to 13.9 g/t Au, 52 g/t Ag, and 1.7% Cu.
The second style of mineralization is also hosted entirely in the granodiorite pluton and comprised of fractured gossanous zones containing abundant fine disseminated pyrite with weak enrichment in gold and arsenic. Prospecting grab samples from the gossanous zones have returned up to 0.54 g/t Au.
The third and final style of mineralization consists of auriferous quartz-arsenopyrite veins hosted in sediments near the granodiorite contact. First pass prospecting along the granite contact returned quartz veins assaying up to 0.51 g/t Au. Furthermore, first pass ridge and spur soil sampling has outlined a robust, 4.5 km long Au-Ag-As +/- Bi-Sb-Te soil geochemical anomaly that coincides with the granodiorite contact and auriferous quartz veins sampled to date. This soil anomaly contains gold values up to 0.8 g/t and silver values up to 1 g/t and remains open to the NW and SE along the granodiorite contact. The geochemical signature of the soil anomaly suggest potential for a gold skarn deposit and is believed to represent the lode source to the placer gold-bearing Willie Jack Creek directly downslope.
This gold skarn soil anomaly has seen no follow up work to date and remains a high priority for the 2021 field season. Detailed prospecting in combination with systematic soil sampling will hopefully expand the anomaly and delineate drill targets for future programs.
