Vancouver, BC (October 27, 2020) Skeena Resources Limited (TSX: SKE, OTCQX: SKREF) (“Skeena” or the “Company” - https://www.commodity-tv.com/ondemand/companies/profil/skeena-resources-ltd/) is pleased to report additional diamond drill core results from the Phase 1 combined campaign of definition and exploration drilling at the Eskay Creek Project (“Eskay Creek” or the “Project”) located in the Golden Triangle of British Columbia. Phase 2 drilling continues with nine drill rigs currently active. The Phase 2 infill program is focused on Pre-Feasibility Study (“PFS”) resource category conversions for the open-pit constrained resources. Reference images are presented at the end of this release as well as on the Company’s website.

Eskay Creek Phase I Infill Drilling – Highlights:

-          3.96 g/t Au, 39 g/t Ag (4.48 g/t AuEq) over 28.50 m (SK-20-310)

-          25.27 g/t Au, 2,185 g/t Ag (54.40 g/t AuEq) over 3.00 m (SK-20-319)

-          3.06 g/t Au, 576 g/t Ag (10.74 g/t AuEq) over 9.00 m (SK-20-365)

-          7.82 g/t Au, 172 g/t Ag (10.11 g/t AuEq) over 12.00 m (SK-20-370)

-          5.27 g/t Au, 26 g/t Ag (5.62 g/t AuEq) over 22.07 m (SK-20-371)

Gold Equivalent (AuEq) calculated via the formula: Au (g/t) + [Ag (g/t) / 75]. True widths range from 70-100% of reported core lengths. Length weighted AuEq composites are 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. Metallurgical processing recoveries have not been applied to the AuEq calculation and are taken at 100%. Samples below detection limit were nulled to a value of zero.

Phase I Infill Drilling Confirms Modelled Mineralization

The recently completed Phase 1 portion of the infill drilling campaign at Eskay Creek confirms the predictability of the Company’s 2019 Mineral Resource Estimate (“MRE”), which was largely informed by historical drilling results. As well, recent drill intercepts of grades and widths in the 21C Zone continue to correlate very well with the modelled Inferred mineralization (see section 10420 below).

Precious metal tenor in the 21C Zone has been upgraded from previous Phase I drill holes as demonstrated by recently completed drill hole SK-20-310 which intersected 3.96 g/t Au, 39 g/t Ag (4.48 g/t AuEq) over 28.50 m. Previously reported flanking drill holes SK-20-302 and SK-20-362 intersected 1.99 g/t AuEq over 49.16 m and 2.06 g/t AuEq over 37.00 m respectively and are situated on section less than 15 m from SK-20-310.

Exploration Update

The Company is now drilling the Phase 2 program with a total of nine helicopter supported drill rigs. 46,700 m have been drilled since the Company re-started drilling at Eskay Creek this past July. An additional two rigs are due to be on site in the coming weeks to facilitate the completion of the remaining 43,000 m to be drilled by the end of December 2020. Turnaround time for sample analysis is currently greater than 25 days and the company is awaiting analytical results for 16,900 m over 132 drill holes.

Exploration drilling at the Company’s Snip gold project (“Snip”) will commence on October 29 with one helicopter-supported drill rig. Resource expansion drilling at Snip is budgeted at 5,000 m.

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 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.
