Skeena Announces Discovery of New Mineralization

Intersecting 2.15 g/t AuEq over 40.67 metres

Vancouver, BC (November 22, 2022) Skeena Resources Limited (TSX: SKE, NYSE: SKE)

(“Skeena” or the “Company”) is pleased to announce the discovery of new Rhyolite-hosted

mineralization located east of the 22 Zone as part of the recently completed 2022 regional and near

mine exploration drilling campaigns at the Eskay Creek gold -silver Project (“Eskay Cr eek” or the

“Project”) in the Golden Triangle of British Columbia. Analytical results and reference images from

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

Discovery of New Mineralization East of 22 Zone

Exploratory drill hole SK-22-1054 has discovered a new occurrence of Rhyolite-hosted mineralization

in an area with no historical drill testing and beyond the extents of Eskay Creek's currently defined pit-

constrained resources. Intersecting 1.79 g/t Au, 32.0 g/t Ag (2.15 g/t AuEq) over 40.67 m, SK-22-

1054 is situated 200 metres east of the 22 Zone starting at a vertical depth of only 23 metres below

surface.

Hosted entirely within Rhyolite breccias, this discovery has the style of mineralization, alteration and

geochemical signature consistent with feeder style mineralization encountered throughout the main

Eskay Creek Deposits. This new discovery remains open in all directions and a dditional work will be

required to determine the geometry of the mineralization.

Discussion on New Mineralization

Supported by modern data and interpretation, this new intersection corroborates the thesis that

additional bodies of mineralization can be present in the general proximity of known zones that

previous operators deemed to be non-prospective. Rhyolite-hosted mineralization was not a focus of

exploration historically due to the high precious metal grade required by previous operators. With the

paucity of historical drilling, the area between the 2 1A West Zone and the 22 Zone which measures

800 metres in strike length, provides additional exploration potential.

“Exploration drilling by Skeena in areas deemed non -prospective by previous operators continues to

identify zones of mineralization with potential to add new, near surface mineralization that could be

incorporated into the near-term development plans for Eskay Creek. Additional drill testing is planned

for next year to follow -up on this success” commented Adrian Newton, Skeena’s Director of

Exploration.

Randy Reichert, Skeena’s President and CEO, goes on to comment “This new discovery suggests

that significant exploration potential still exists in areas proximal to synvolcanic feeder structures where

there has been very limited historical drill testing, and in particular, between the Feasibility Study Main

Pit and South Pit.”

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 Dis closure for Mineral Projects, Adrian

Newton, P.Geo. Director of Exploration, 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 bl anks 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 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 mult i-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 Co upled 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 “mineral

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 Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) “CIM Definition Standards – For Mineral

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

standards differ significantly from the mineral 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 mineralization 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 assume 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 economi c and legal feasibility.

Accordingly, investors are cautioned not to assume that any “measured”, “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 economic 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 feasibility or prefeasibility studies, except in ra re

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.
