VANCOUVER, BC, April 6, 2021 /CNW/ - Stuhini Exploration Ltd. (the "Company" or Stuhini") (TSXV: STU) (USA: STXPF) is pleased to announce the discovery of high-grade silver mineralization at the newly identified Silver Surprise Target ("Silver Surprise"), on its Ruby Creek Project (the "Property" or the "Project"). The discovery is approximately 5 kilometres ("km") northeast, and on trend with the recently expanded Adera Corridor silver target (see January 18th, 2021 news release) and 3 km north of the Daybreak target.
Silver Surprise Highlights
- 12 rock samples taken with assay results ranging up to 14,179 grams/tonne silver ("g/t Ag") Ag to 391 g/t Ag.
- All 12 samples were taken over a surface trace of approximately 170 metres ("m") and were of quartz vein material ("QV").

Dave O'Brien, Stuhini's President and CEO commented: "The discovery of such high silver grades at surface and on trend with what could potentially be a continuation of the Adera Corridor is very exciting. We continue to be pleased with the results from our summer 2020 exploration program and we are looking forward to following up on this target and all other prospective targets uncovered from last year's program."
Geology
Mineralization consists of fine-grained sulfides and sulfosalts hosted in a quartz-carbonate vein. The outcropping vein strikes NE-SW and is steeply dipping. The exact thickness of the mineralized zone is unknown at this time as most mineralization is observed as subcrop or felsenmeer, but is estimated to be comparable to the widths reported at the Atlin-Ruffner silver mine, approximately 1 to 3 metres wide. An additional 8 silver bearing rock samples were taken approximately 250 metres south (6 samples) and 1200 metres northwest (2 samples) of the high-grade assays. Samples assayed up to 208 g/t Ag and 13.73 % lead ("Pb") indicating the presence of additional silver bearing structures within close proximity. Note that rock grab samples are selective by nature and values reported may not represent the true grade or style of mineralization across the property. The tables below summarize these additional samples.

Daybreak Target: Following up on last years results (see September 4th, 2020 news release), the exploration team were sent to further investigate the silver occurrences in this target area. Of the rock samples taken, 14 of 73 samples assayed greater than 25 g/t Ag with one quartz vein sample assaying 772 g/t of silver and 0.28 g/t gold. Five samples with notable silver are from the Daybreak skarn showing.
A summary of select rock sample assays results is listed in the table below.

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 was performed on all samples. Over-limit copper, lead, zinc and silver samples were analyzed by multi-acid digestion and ICP-ES (MA370). Silver samples >1500 g/t were also analyzed by fire assay (FA530). All results have passed the QA/QC screening by the lab.
Ruby Creek Project: The 27,354-hectare Ruby Creek Project is road accessible and located 20 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.
