VANCOUVER, BC, May 4, 2021 /CNW/ - Stuhini Exploration Ltd. (the "Company" or Stuhini") (TSXV: STU) is pleased to announce further results of its 2020 field program and identified gold targets on its Ruby Creek Project (the "Project" or "Property" or "Ruby Creek") located 20 kilometres (km) east of Atlin, BC.
Highlights include the following grab samples:
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.
Dave O'Brien, Company President and CEO, commented; "We are excited to add these new gold targets to our exploration objectives and this futher exhibits the prospectivity of our Ruby Creek tenures. None of these targets have seen any exploration work for several decades, thus we are hopeful that new advances and increased breadth and resolution of modern geophysical and geochemical methods will lead to further advancements."
Southwest Property Targets: Birch Creek, Boulder Creek, and Lakeview
The southwest portion of the Property includes the Birch, Boulder and Lakeview targets. Both Birch and Boulder Creek were important placer creeks in the Atlin area with Boulder Creek being the third largest gold producer in the area. Mineralization occurs in quartz veins hosted within the Cache Creek complex.
i) Birch Creek Target
The Birch Creek target includes the historic Little Edna showing. Previous operators focussed on the more prominent north striking and steeply dipping gossanous structure hosting polymetallic base metal sulfides and silver mineralization with no significant gold. During the 2020 field program, gold mineralization was discovered in separate quartz veins on the periphery of the main Little Edna structure. The gold mineralization is hosted within narrow, 5 to 20 cm wide, steeply dipping, northeast striking, en echelon quartz-carbonate veins that appear to widen towards Birch Creek. Birch Creek is interpreted to be a major fault and conduit for hydrothermal fluids responsible for the placer gold in the area. Anomalous gold values were encountered in 3 of the 4 vein samples. The samples were also anomalous in bismuth and tellurium and absent in base metal mineralization. The highest grade samples taken 30 metres south of the Little Edna structure returned values of 6.03 g/t Au and 51.6 g/t Ag. Table 1 summarizes the Little Edna samples.

ii) Boulder Creek Target
The Boulder Creek target is focused on gold mineralization in the vicinity of the historic Sunbeam showing on the west side of Boulder Creek. Mineralization is found within quartz vein material that is most likely hosted within the Cache Creek Complex. The Sunbeam showing is described in a Minister of Mines Annual Report in 1904, and the exact location uncertain. To date, several angular proximal float boulders of gold-bearing quartz have been found in the area with grades as high as 121.34 g/t Au and 2,093 g/t Ag and the previously reported 78 g/t Au and 1,282 g/t Ag (see June 29, 2020 press-release). Further work on this compelling target is planned for the upcoming field season.

iii) Lakeview Target
The historic Lakeview showing consists of gold bearing quartz veins hosted in intermediate to mafic volcanic rocks of the Cache Creek Complex. The target has not received any significant exploration since 1987. Samples in the 2020 program are from steeply dipping north-northeast trending quartz-carbonate veins and assayed as high as 34.08 g/t Au and 494 g/t Ag. Table 2 summarizes the Lakeview assays.
In addition to prospecting and rock sampling, 25 soil samples were collected along a line perpendicular to a geophysical anomaly identified in the 2020 SkyTEM survey. Two gold in soil anomalies have been recognized on this line, including a 100 metre long anomaly and a second single sample anomaly at the very end of the line (see Figure 3 below). An expanded soil geochemistry survey will be conducted over the areas of interest 2021 field season.

Ruby Creek Gold Target
The Ruby Creek Gold target area begins approximately half a km east of the historic Adanac molybdenum resource and extends into upper Ruby Creek. Ruby Creek was the fourth highest gold producing creek in the Atlin Placer Camp.
Mineralization consists of gold, silver, lead, copper and tungsten in quartz veins, quartz vein stockwork, and breccias hosted within the Surprise Lake Batholith. Assays of up to 10 g/t Au were returned from the 2020 program (Table 3). The target area also encloses two historic diamond drill holes from 2008. The two holes were part of the condemnation drilling for the proposed Adanac open-pit molybdenum mine. The holes are more than 950 metres apart and intersected 76.2 metres averaging 0.15 g/t Au and 73.2 metres averaging 0.21 g/t Au respectively (Table 4), including a 3 metre sample assaying 0.6 g/t Au. Both holes were drilled within the Surprise Lake Batholith.

In other Company news, Stuhini wished to announce that despite challenging weather, it has successfully completed its recently announced 2021 SkyTEM airborne geophysical survey on key remaining portions of its Ruby Creek Project. Company consulting geophysicist Todd Ballantyne will be reviewing and compiling results in the coming months, which will help Company geologists define exploration targets for the upcoming 2021 exploration program. The Company also wishes to announce that it has received a 5 year drill permit for the Ruby Creek Project. Lastly, on April 22nd the Company hosted it's first webinar with a series of live corporate presentations. A video recording of the webinar has been posted on the home page of our website – we encourage those of you who were not able to attend the presentations to view the recording so as to better appreciate and understand the Company and its suite of assets.
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). Conversion to WO3 % = W % x 1.2616. 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.
