VANCOUVER, BC, Dec. 15, 2020 /CNW/ - Stuhini Exploration Ltd. (the "Company" or "Stuhini") (TSXV: STU) is pleased to report assay results from the Silver Diamond and Copper Valley prospects on its Ruby Creek Project (the "Property or Project") located 20 kilometres (km) east of Atlin, BC.

The Silver Diamond and Copper Valley prospects are located in close proximity to the past producing Black Diamond Tungsten Mine, a northeast trending vein with reported tungsten, copper, gold and silver mineralization. The prospects coincide with electromagnetic (EM) and magnetic anomalies identified in the airborn SkyTEM survey conducted in the spring of 2020 (see June 12, 2020 news-release). Follow up prospecting, geologic mapping, outcrop sampling and diamond saw channel sampling has identified skarn mineralization consisting of  disseminated to semi-massive pyrrhotite lenses with chalcopyrite, sphalerite, scheelite and galena. The prospects as well as the Black Diamond vein are hosted within metavolcanic and metasedimentary rocks of the Upper Paleozoic Cache Creek Complex in close proximity to alaskite of the Mount Leonard Boss, a small stock separated from the main body of the Late Cretaceous Surprise Lake Batholith.

The Silver Diamond prospect is located on the west side of the placer gold producing Boulder Creek and appears to be within the same northeast striking Black Diamond structure identified within the SkyTEM magnetics. A 22 metre long channel sample was taken from polished outcrop using a portable diamond saw. Highlights of sampling include 3.5 metres of 116.8 g/t silver, 11.55% zinc, 0.28% copper and 0.11% lead.

Eight grab samples were also taken from a 3 metre exposure, approximately 10 metres west of the channel samples. This is believed to be an additional horizon of skarn mineralization. Various grab samples from this outcrop returned assays as high as 1.22 g/t gold, 0.46% copper, 64.1 g/t silver and 0.25% tungsten oxide. Table 1 is a summary of the results for the Silver Diamond Prospect.

Table 1 – Sample Results from the Silver Diamond Prospect

The Copper Valley prospect is located north and east of the Black Diamond Tungsten Mine. Additional mapping, propecting and sampling was conducted in this area, following up on results reported earlier in the season (see June 29, 2020 news-release). Seven grab samples were taken from outcropping skarn mineralization, with multiple samples returning significant zinc, copper, lead and tungsten oxide values. Table 2 is a summary of the results for the Copper Valley prospect.

Table 2 - Sample Results from the Copper Valley Prospect

Dave O'Brien, Company President and CEO commented: "The Ruby Creek Project continues to generate numerous targets. The mineralization and electromagnetic anomaly observed at the Silver Diamond prospect deserves further exploration. Multiple comparable electromagnetic anomalies occur within the Copper Valley area and these are currently untested and under-explored."

QA/QC: Rock material was collected in poly bags and then transported to the Bureau Veritas sample preparation facility located in Whitehorse, Yukon Territory. 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 was 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). All results have passed the QAQC screening by the lab.

Other Targets: The Company is presently compiling assay data as it comes in from other targets on the Project and will be reporting further exploration updates as these compilations are completed.

Ruby Creek Project:  The 27,354-hectare Ruby Creek Project is road accessible and located 20 kilometres (km) east of Atlin, BC. There are 48 different documented mineral occurrences on the Property, of which 16 are gold-related, with 4 active gold placer creeks. The Property also hosts the historic Ruby Creek Molybdenum resource, which has an intact BC mines act permit. Stuhini has an option to acquire 100% of the Ruby Creek Project subject to a 1% Net Smelter Royalty.
