Drill Results

Skeena Bolsters 21A West Zone Intersecting

18.18 g/t Au, 130.2 g/t Ag over 9.26 metres

Vancouver, BC ( February 22 , 202 3) Skeena Resources Limited (TSX: SKE, NYSE: SKE)

(“Skeena” or the “Company”) is pleased to announce drilling results from the 2022 regional and near

mine exploration and delineation campaigns at the Eskay Creek gold-silver Project (“Eskay Creek” or

the “Project”) in the Golden Triangle of British Columbia. This release completes the reporting for

remaining drill holes from the 2022 p rogram. Analytical results and reference images are detailed in

this release as well as on the Company’s website.

2022 Near Mine Exploration Drilling Highlights:

• 18.18 g/t Au, 130.2 g/t Ag over 9.26 m (SK-22-1132) - 21A West Zone

• 14.90 g/t Au, 2.5 g/t Ag over 5.70 m (SK-22-1177) - 21A West Zone

• 0.95 g/t Au, 1,003.3 g/t Ag over 6.42 m (SK-22-1187) - 23 Zone

• 1.11 g/t Au, 19.7 g/t Ag over 26.10 m (SK-22-1187) - 23 Zone

• 4.96 g/t Au, 14.6 g/t Ag over 25.98 m (SK-22-1171) - 21E Zone

• 3.39 g/t Au, 34.4 g/t Ag over 23.77 m (SK-22-1160) - 21E Zone

• 2.78 g/t Au, 59.0 g/t Ag over 20.49 m (SK-22-1173) - 21E Zone

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 composites. Samples below detection limit were nulled to a value of zero.

New Mineralization Expands 21A West Zone

Situated at a vertical depth of 25 metres below surface, drill hole SK-22-1132 has vertically extended

the 21A West Zone to near -surface with an intersection of 18.18 g/t Au, 130.2 g/t Ag over 9.26 m .

This new intercept occurs in a portion of the 21A Zone that is devoid of historical drilling and 75 metres

vertically up-dip of previously reported Skeena drill hole SK -22-1031, which intersected 2.21 g/t Au,

4.6 g/t Ag over 50.00 m.

An additional extension to the south end of the 21A West Zone just beyond the Feasibility Study pit

limits and only 10 metres below surface was completed by drill hole SK-22-1177, averaging 14.90 g/t

Au, 2.5 g/t Ag over 5.70 m . This new expansion occurs 100 m etres vertically up -dip of previously

reported drill hole SK-22-1028, which intersected 1.74 g/t Au, 1.7 g/t Ag over 46.77 m. The space

between the two drill holes remains untested.

The 21A West Zone has been defined by 2022 drilling over a 350 metre strike length from surface to

200 metres below surface. Horizontal widths of the zone vary and range from thickness es of 1 to 50

metres. The 21A West Zone remains open for expansion along strike as well as at depth.

23 Zone Continues to Develop

New rhyolite and dacite hosted mineralization analogous to that observed in the 23 Zone has been

discovered south of the 21E Zone. Drill hole SK-22-1187 intersected two noteworthy horizons, the first

NR: 23-05 | February 22, 2023

of which is argentiferous and occurs at surface grading 0.95 g/t Au, 1,003.3 g/t Ag over 6.42 m. The

second occurrence, averaging 1.11 g/t Au, 19.7 g/t Ag over 26.10 m, is situated 65 metres vertically

below surface in a previously untested northern extension of the 23 Zone.

To date, the mineralized horizons comprising the 23 Zone have been traced by variably spaced

exploratory drilling from the 21E Zone south for approximately 8 00 metres. Drilling has outli ned

mineralization from surface to more than 300 metres below surface and remains open for expansion.

21E Zone Exploration and Delineation

Exploration and delineation drilling within the area surrounding the 21E Zone was targeted at

mineralization analogous to that observed along strike in the 23 Zone. New dacite hosted

mineralization was encountered by SK-22-1170, averaging 1.01 g/t Au, 37.9 g/t Ag over 21.21 m ,

located 35 metres below the Feasibility Study pit shell.

Previously defined 21E Zone resources were corroborated by the 2022 drill holes in this area as they

tested mineralization below and along strike of the known resources. Highlights include 4.96 g/t Au,

14.6 g/t Ag over 25.98 m, 3.39 g/t Au, 34.4 g/t Ag over 23.77 m and 2.78 g/t Au, 59.0 g/t Ag over

20.49 m in drill holes SK-22-1171, SK-22-1160 and SK-22-1173, respectively.

Expected Timing of Mineral Resource Estimate

The 21A West Zone and 23 Zones were discovered by Skeena in 2021 and represent rhyolite-dacite

hosted synvolcanic feeder style mineralization that has not yet been included in any Mineral Resource

Estimates (“MRE”) or economic analyses. With all analytical results now received from the 2022 drilling

program, the Company will be incorporating all drilling data from after September 2021 into an updated

MRE scheduled for completion in H1 2023.

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 re serve”, “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, Metall urgy 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 mineral property disclosure requiremen ts of t he 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 informa tion ma y 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 Skee na’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 “measured”, “indicated”, or “inferr ed” 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 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.
