Skeena Announces High-Grade In-Pit Extension of 21A West Zone

Intersecting 7.91 g/t AuEq over 17.20 metres

Vancouver, BC (November 17, 2022) Skeena Resources Limited (TSX: SKE, NYSE: SKE)

(“Skeena” or the “Company”) is pleased to announce additional drilling results from the 21A West Zone

delineation program as part of the recently completed 2022 regional and near mine exploration

campaigns at the Eskay Creek gold -silver Project (“Eskay Creek” or the “Project”) in the Golden

Triangle of British Columbia. Analytical results and reference images from the recently completed drill

holes are detailed in this release as well as on the Company’s website.

Assay Results Extend 21A West Zone Further to the South

In an area previously modeled as barren waste rock, e xploratory drill hole SK -22-1131 intersected

high tenor gold and silver mineralization in Rhyolite facies rocks starting at 14 metres vertically below

surface averaging 7.73 g/t Au, 16.8 g/t Ag (7.91 g/t AuEq) over 17.20 m with notable high -grade

subintervals including 9.47 g/t Au, 13.7 g/t Ag (9.62 g/t AuEq) over 4.02 m and 14.61 g/t Au, 31.3

g/t Ag (14.96 g/t AuEq) over 5.20 m . This drill hole is situated within the proposed open-pit and 35

metres along trend to the south of previously reported 2022 drill hole SK -22-1031, which intersected

2.21 g/t Au, 4.6 g/t Ag (2.27 g/t AuEq) over 50.00 m.

Additional near surface Rhyolite mineralization has also been encountered by the exploratory drill hole

SK-22-1103, grading 3.08 g/t Au, 32.9 g/t Ag (3.45 g/t AuEq) over 21.80 m and 4.52 g/t Au, 84.7

g/t Ag (5.46 g/t AuEq) over 9.75 m, located within the proposed open-pit and 35 metres to the south

of SK-22-1131.

Due to a lack of historical drilling, this area of the 21A West Zone was considered barren waste rock

for both the 2022 Resource Estimate and Feasibility Study. Th e recently discovered feeder-style

mineralization that occurs within the Feasibility Study pit will be incorporated into the future resource

and economic updates for Eskay Creek through incorporation of the 68,543 metres of exploration

drilling completed since September 2021. As highlighted in the cross-section below, drill holes SK-22-

1103, SK-22-1104 and SK-22-1131 have successfully contributed to the continued expansion and

validation of the 21A West Zone discovered in late 2021. The 21A West Zone remains open for

expansion both down-dip and along strike.

About Skeena

Skeena Resources Limited is a Canadian mining exploration and development 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 Feasibility Study for Eskay

Creek in September 2022 which highlights an open -pit average grade of 4.00 g/t AuEq, an after -tax

NPV5% of C$1.4B, 50% IRR, and a 1-year payback at US$1,700/oz Au and US$19/oz Ag. Skeena is

continuing exploration drilling at Eskay Creek.

Gold Equivalent (AuEq) calculated via the formula: Au (g/t) + [Ag (g/t) / 90]. True widths and zone

geometries cannot be definitively determined at this time. 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.

Qualified Persons

Exploration activities at the Eskay Creek Project are administered on site by the Company’s

Exploration Manager, Raegan Markel, P.Geo. and Director of Exploration, Adrian Newton P.Geo. In

accordance with National Instrument 43 -101 Standards of Disclosure f or Mineral Projects, Adrian

Newton, P.Geo. 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 conducti ng, 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, Senior Vice President Exploration and Resource

Development.

Drill core samples are submitted to ALS Geochemistry’s analytical facility in North Van couver, 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.

Cautionary note to U.S. Investors concerning estimates of mineral reserves and mineral resources

Skeena’s mineral reserves and mineral resources included or incorporated by reference herein have been estimated in

accordance with National Instrument 43 -101 – Standards of Disclosure for Mineral Projects (“NI 43 -101”) as required by

Canadian securities regulatory authorities, which differ from the requirements of U.S. securities laws. The terms “mine ral

reserve”, “proven mineral reserve”, “probable mineral reserve”, “mineral resource”, “measured mineral resource”,

“indicated mineral resource” and “inferred mineral resource” are Canadian mining terms as defined in accordance with NI

43-101 and the Cana dian Institute of Mining, Metallurgy and Petroleum (“CIM”) “CIM Definition Standards – For Mineral

Resources and Mineral Reserves” adopted by the CIM Council (as amended, the “CIM Definition Standards”). These

standards differ significantly from the minera l property disclosure requirements of the U.S. Securities and Exchange

Commission in Regulation S-K Subpart 1300 (the “SEC Modernization Rules”). Skeena is not currently subject to the SEC

Modernization Rules. Accordingly, Skeena’s disclosure of mineraliza tion and other technical information may differ

significantly from the information that would be disclosed had Skeena prepared the information under the standards

adopted under the SEC Modernization Rules.

In addition, investors are cautioned not to assum e that any part or all of Skeena’s mineral resources constitute or will be

converted into reserves. These terms have a great amount of uncertainty as to their economic and legal feasibility.

Accordingly, investors are cautioned not to assume that any “meas ured”, “indicated”, or “inferred” mineral resources that

Skeena reports are or will be economically or legally mineable. Further, “inferred mineral resources” have a great amount

of uncertainty as to their existence, and great uncertainty as to their econo mic and legal feasibility. It cannot be assumed

that all or any part of an “inferred mineral resource” will ever be upgraded to a higher category. Under Canadian securities

laws, estimates of “inferred mineral resources” may not form the basis of feasibili ty or prefeasibility studies, except in rare

cases where permitted under NI 43 -101. For these reasons, the mineral reserve and mineral resource estimates and

related information presented herein may not be comparable to similar information made public by U.S. companies subject

to the reporting and disclosure requirements under the U.S. federal securities laws and the rules and regulations

thereunder.
