Skeena Intersects 155.76 g/t Au Over 3.22 Metres at Snip Gold Project

VANCOUVER, BC / ACCESSWIRE / May 20, 2021 / Skeena Resources Limited (TSX:SKE)(OTCQX:SKREF) (“Skeena” or the “Company”) is pleased to report diamond drill core results from the 2021 Phase 3 infill and exploration drilling program at the Snip gold project (“Snip” or the “Project”) located in the Golden Triangle of British Columbia. The Phase 3 program is designed to upgrade areas of existing Inferred resources from the Company’s 2020 Mineral Resource Estimate (MRE), to the Measured and Indicated categories. Reference images are presented at the end of this release as well as on the Company’s website.

Snip 2021 Phase 3 Drilling Highlights:

• 155.76 g/t Au over 3.22 m (S21-076)
• 140.50 g/t Au over 0.50 m (S21-078)
• 8.40 g/t Au over 3.00 m (S21-080)
• 61.30 g/t Au over 0.50 m (S21-083)

True widths range from 60-90% of reported core lengths. Length weighted Au composites are constrained by geological considerations. Grade-capping of individual assays has not been applied to the Au assays informing the length-weighted Au composites. Samples below detection limit were nulled to a value of zero.

New High-Grade Mineralization Intersected Below Twin Zone
Situated in the footwall sediments below the Twin Zone, occurrences of high tenor, vein-hosted mineralization have been intersected grading 155.76 g/t Au over 3.22 m including 376.00 g/t Au over 0.89 m and 194.00 g/t Au over 0.83 m (S21-076), and 140.50 g/t Au over 0.50 m (S21-078). These surface-based drill holes were targeting Inferred resources hosted by footwall veins that were previously only populated by widely spaced, selectively sampled historical drill holes in this area of the deposit. The new high-grade mineralization, defined by S21-076, occurs hanging-wall to the known footwall veins.

Additional footwall vein-hosted mineralization was also encountered by surface drill hole S21-080 which intersected 8.40 g/t Au over 3.00 m including 12.20 g/t Au over 1.50 m. This drill hole intersection occurs 100 m northwest S21-076 and correlates spatially with the modelled resources.

2021 Phase 3 Program Description
The 2021 drilling program at Snip is designed to convert Inferred resources from the Company’s 2020 MRE to higher confidence categories (Measured and Indicated) through surface and underground drilling. Dedicated geotechnical drilling is also being completed at the Project. Approximately 3,100 m of surface-based drilling and 8,000 m of underground drilling remain to be completed in 2021. The Company is currently operating two underground rigs at Snip and additional surface rigs will be added once permits are received.

About Skeena
Skeena Resources Limited is a Canadian mining exploration company focused on revitalizing the past-producing Eskay Creek gold-silver mine located in Tahltan Territory in the Golden Triangle of northwest British Columbia, Canada. The Company released a robust Preliminary Economic Assessment in late 2019 and is currently focused on infill and exploration drilling to advance Eskay Creek to full Feasibility by Q1 2022. Additionally, Skeena continues exploration programs at the past-producing Snip gold mine.

Qualified Persons
Exploration activities at the Snip Project are administered on site by the Company’s Exploration Managers, Raegan Markel, P.Geo. and John Tyler. In accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects, Paul Geddes, P.Geo. Vice President Exploration and Resource Development, is the Qualified Person for the Company and has prepared, validated and approved the technical and scientific content of this news release. The Company strictly adheres to CIM Best Practices Guidelines in conducting, documenting, and reporting the exploration activities on its projects.

Quality Assurance – Quality Control
Once received from the drill and processed, all drill core samples are sawn in half, labelled and bagged. The remaining drill core is subsequently securely stored on site. Numbered security tags are applied to lab shipments for chain of custody requirements. The Company inserts quality control (QC) samples at regular intervals in the sample stream, including blanks and reference materials with all sample shipments to monitor laboratory performance. The QAQC program was designed and approved by Lynda Bloom, P.Geo. of Analytical Solutions Ltd., and is overseen by the Company’s Qualified Person, Paul Geddes, P.Geo, Vice President Exploration and Resource Development.

Drill core samples are submitted to ALS Geochemistry’s analytical facility in North Vancouver, British Columbia for preparation and analysis. The ALS facility is accredited to the ISO/IEC 17025 standard for gold assays and all analytical methods include quality control materials at set frequencies with established data acceptance criteria. The entire sample is crushed and 1 kg is pulverized. Analysis for gold is by 50 g fire assay fusion with atomic absorption (AAS) finish with a lower limit of 0.01 ppm and upper limit of 100 ppm. Samples with gold assays greater than 100 ppm are re-analyzed using a 50 g fire assay fusion with gravimetric finish. Analysis for silver is by 50 g fire assay fusion with gravimetric finish with a lower limit of 5ppm and upper limit of 10,000 ppm. Samples with silver assays greater than 10,000 ppm are re-analyzed using a gravimetric silver concentrate method. A selected number of samples are also analyzed using a 48 multi-element geochemical package by a 4-acid digestion, followed by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) and Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) and also for mercury using an aqua regia digest with Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) finish. Samples with sulfur reporting greater than 10% from the multi-element analysis are re-analyzed for total sulfur by Leco furnace and infrared spectroscopy.
