Stuhini Identifies Native Gold with Copper, Silver and Tungsten in both Historical Drilling and Current Surface Sampling within the Surprise Lake Batholith, Atlin, BC, Canada
VANCOUVER, BC, Jan. 12, 2022 /CNW/ - Stuhini Exploration Ltd. (the "Company" or "Stuhini") (TSXV: STU) is pleased to provide an update on gold exploration work at the Ruby Creek Project, 14 kilometres east of Atlin, BC, Canada.
Highlights from 2021 Sampling

- native gold identified in two historic condemnation drill holes.
- Assays of 5.72 g/t Au, 167 g/t Ag, 0.18 % Cu and 1.35 % WO3 over 1.75 metres, including 9.27 g/t Au, 225 g/t Ag, 0.30 % Cu and 2.19 % WO3 over 1 metre from the extension of the Black Diamond Vein.
- 49 rock samples, of which 20 assayed over 1.0 g/t Au, and as high as 28.5 g/t Au, 1431.0 g/t Ag.
- 28 of these samples are from the northeast extension of the Black Diamond Vein, tripling the length of the known vein system
The Company has defined a one-kilometre-long gold trend extending from the historical Adanac Molybdenum resource southwest along Thor Ridge. The ridge hosts numerous veins including the Black Diamond and Emil veins. Surface sampling along this trend has confirmed the presence of gold, copper, silver, and tungsten mineralization. Current work has also identified native gold in two historic condemnation drill holes from 2008 (AD390 and AD393).
David O'Brien, President and CEO commented "The identification of free gold in sheeted veinlets from the historic Adanac Molybdenum condemnation drill core is great news as it supports our speculation of a potential intrusion-related gold bearing system in the area and another possible source for the incredible placer gold endowment of Ruby Creek and the Atlin camp."
The condemnation drill holes are two kilometres east of the main molybdenum resource area and contain the following:
- AD-393 - 73.2 M @0.21g/t Au, 0.28g/t Ag
- AD-390 - 76.2m @0.15g/t Au, 0.42g/t Ag, including 21.35m @0.21g/t Au, and 0.11g/t Ag.
The Mineral Deposit Research Unit (MDRU) at the University of British Columbia performed detailed analytical work on the gold intersections from condemnation drill holes AD-393 and AD-390. Using a scanning electron microprobe (SEM) and an automated mineralogical procedure optimized to recognize gold, electrum was identified consisting of approximately 50% gold and 50% silver. The electrum is associated with bismite or bismuthinite and pyrite rimed by pyrrhotite within a 20 millimeter to sub-millimeter wide quartz vein hosted within the Surprise Lake Batholith (AD-390 at 34.6 metres). Many other veinlets with similar sulfide compositions also contained wolframite.
Four gold-bearing quartz-wolframite-scorodite-arsenopyrite bearing structures on Thor Ridge are hosted in the Surprise Lake Batholith and anomalous in bismuth and antimony. The sub-vertical structures identified on the ridge and the Black Diamond vein are on trend with the condemnation drill holes. It is speculated that these higher grade auriferous structures are peripheral to a potential bulk tonnage gold target that was intersected in the condemnation drilling and may be comparable to Victoria Gold's Eagle Gold Mine in the Yukon Territory to the north, a Reduced Intrusion-Related Gold Systems.

QA/QC Protocol: Rock material was collected in poly bags and then transported to the Bureau Veritas sample preparation facility located in Whitehorse, Yukon. Samples were crushed, and then pulps were sent to the Bureau Veritas lab in Vancouver for assay. Four acid digestion and Ultratrace ICP-MS analysis for 59 elements and fire assay for gold, platinum and palladium were performed on all samples. Over-limit copper, lead, zinc and silver samples were analyzed by multi-acid digestion and ICP-ES (MA370). Over-limit tungsten was analyzed with lithium borate fusion XRF (XF750). Conversion to WO3 % = W % x 1.2616. All results have passed the QA/QC screening by the lab.
