Skeena Discovers Mineralization at Eskay Deeps

• 12.67 g/t Au, 22 g/t Ag (12.96 g/t AuEq) over 14.50 m (SK-20-289)
  • Including: 28.70 g/t Au, 29 g/t Ag (29.09 g/t AuEq) over 1.30 m
• 5.75 g/t Au, 14 g/t Ag (5.94 g/t AuEq) over 11.00 m (SK-20-289)
  • Including 13.25 g/t Au, 23 g/t Ag (13.56 g/t AuEq) over 1.50 m

Gold Equivalent (AuEq) calculated via the formula: Au (g/t) + [Ag (g/t) / 75]. True widths cannot be estimated at this time due to a lack of information. Length weighted AuEq composites were constrained by geological considerations. Grade capping of individual assays has not been applied to the Au and Ag assays informing the length weighted AuEq composites. Processing recoveries have not been applied to the AuEq calculation and are disclosed at 100%. Samples below detection limit were nulled to a value of zero.

Multiple Mineralized Zones Identified in New Eskay Deeps
Exploration drilling has intersected significant mineralization in the recently recognized Eskay Deeps prospect, situated 600 m vertically below surface in a previously unexplored area of the Project. This previously unidentified mineralization occurs greater than 260 m vertically below the lower extents of the currently modelled WTZ and is open in all directions. Mineralization in this new area occurs as discordant, pyritic replacements devoid of impurities (Hg-As-Sb) and is hosted within the ELM and Lower Andesite sequence. The intersected apparent thickness of the ELM at this location is approximately 125 m. Due to a lack of any other supporting drill holes in this new area, true widths cannot yet be estimated.

Water Tower Zone Expanded by Drilling - New Mineralized Feeder Structure
The known mineralization in the WTZ has been expanded downdip by this recent drilling. Up-hole of the main WTZ, another new occurrence of feeder-style, discordant mineralization was intersected to the west, hosted within intensely sericitized and silicified rhyolite breccias. This newly found mineralization potentially represents a previously unidentified second syn-volcanic feeder structure parallel to the WTZ. At greater depths, a substantial thickness (160 m), of ELM was intersected averaging only trace gold-silver mineralization. This remains very prospective.

"The discovery of multiple zones of ELM-hosted mineralization in the new Eskay Deeps adds significant exploration upside to the current resource base", comments Paul Geddes, P.Geo., the Company's Vice President Exploration & Resource Development. "Our success rate to date with only a handful of exploratory drill holes emphasizes the untapped growth potential and magnitude of the Eskay Creek mineralized system".

About Skeena
Skeena Resources Limited is a junior mining company focused on developing 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 at Eskay Creek to advance the project to Prefeasibility. Skeena is also exploring the past-producing Snip gold mine.

Qualified Persons
Exploration activities at the Eskay Creek Project are administered on site by the Company's Exploration Managers, Colin Russell, P.Geo. and Adrian Newton, P.Geo. 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 1kg is pulverized. Analysis for gold is by 50g 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 100ppm are re-analyzed using a 50g fire assay fusion with gravimetric finish. Analysis for silver is by 50g fire assay fusion with gravimetric finish with a lower limit of 5ppm and upper limit of 10,000ppm. Samples with silver assays greater than 10,000ppm are re-analyzed using a gravimetric silver concentrate method. A selected number of samples are also analyzed using a 48 multi-elemental 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.
