Skeena Announces 21A West Zone Expansion Discovery at Eskay Creek

Including 8.95 g/t AuEq over 34.00 metres

Vancouver, BC (March 9, 2022) Skeena Resources Limited (TSX: SKE, NYSE: SKE) (“Skeena” or

the “Company”) is pleased to announce final drilling results from the 2021 regional and near mine

exploration programs at the Eskay Creek gold-silver Project (“Eskay Creek” or the “Project”) in the

Golden Triangle of British Columbia. Analytic al results from the recently completed drill holes are

detailed in this release. Reference images are presented at the end of this release as well as on the

Company’s website.

New 2021 Exploration Program Highlights:

• 1.29 g/t Au, 36 g/t Ag (1.76 g/t AuEq) over 14.50 m (SK-21-972)

• 0.79 g/t Au, 26 g/t Ag (1.14 g/t AuEq) over 21.11 m (SK-21-972)

• 1.77 g/t Au, 200 g/t Ag (4.44 g/t AuEq) over 11.73 m (SK-21-983)

• 0.78 g/t Au, 120 g/t Ag (2.39 g/t AuEq) over 11.50 m (SK-21-985)

• 8.78 g/t Au, 13 g/t Ag (8.95 g/t AuEq) over 34.00 m (SK-21-997)

Gold Equivalent (AuEq ) calculated via the formula: Au (g/t) + [Ag (g/t) / 75]. 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.

New In-Pit Discovery Expands 21A Zone

Following up on resource category conversion drilling performed in early 2021, exploratory drill hole

SK-21-997 intersected high -grade gold mineralization averaging 8.78 g/t Au, 13 g/t Ag (8.95 g/t

AuEq) over 34.00 m located 60 m west of Skeena’s current 21A Zone pit -constrained resources.

Hosted entirely within the rhyolite sequenc e, this new mineralization is only 30 m vertically below

surface. This discovery remains open for expansion 120 m to the north and already occurs within the

limits of the contemplated open-pit from Skeena’s 2021 Prefeasibility Study (“PFS”). The high-grade

gold and essentially negligible silver concentrations in this new intersection is u ncharacteristic of

rhyolite hosted mineralization at Eskay Creek. Refer to Table 1 below.

“Due to a lack of drilling, this new discovery which expands the 21A Zone to the west, was considered

waste rock in the currently proposed PFS reserve pit area,” notes Paul Geddes P.Geo., the Company’s

Vice President of Exploration and Resource Development . “We will work to expand and infill drill the

21A West Zone and potentially bolster th e pit -constrained resources surrounding this new ly

discovered mineralization”.

Other Near Mine Targets

Additional mineralization has been discovered between the 21A and 23 Zones highlighted by drill hole

SK-21-972, which intersected three intervals averaging 1.29 g/t Au, 36 g/t Ag (1.76 g/t AuEq) over

14.50 m, 0.79 g/t Au, 26 g/t Ag (1.14 g/t AuEq) over 21.11 m and 1.14 g/t Au, 23 g/t Ag (1.45 g/t

AuEq) over 13.50 m. These intervals are hosted within the footwall da cite series as is the case with

the recently discovered 23 Zone.

2022 Exploration Outlook

The Company is anticipating a staged drilling startup beginning in early Q2 2022 , focusing on near

mine and regional targets that were not explored during the 2021 drilling program. Overall, 60,000 m

has been allocated to the 2022 exploration program which will continue to focus on supplementing the

existing mine plan with additional near surface mineralization amenable to open-pit mining methods

and will be paralleled by exploratory drill testing of the deep Mudstone extensions north of the former

Eskay Creek mine. Allocation of meterage will remain results driven. Expansion and delineation drilling

will also occur in the new 21A West Zone as well as the recently discovered 23 Zone.

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 resourc e” 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 amended, the “CIM Definition

Standards”). The U.S. Securities and Exchange Commission (the “SEC”) has mineral property disclosure rules in Regulation S -K

Subpart 1300 applicable to issuers with a class of securities registered under the Securities Exchange Act of 1934 (the “Exchange Act”),

which rules were updated effective February 25, 2019 (th e “SEC Mineral Property Rules”) with compliance required for the first fiscal

year beginning on or after January 1, 2021. Skeena is not required to provide disclosure on its mineral properties under the SEC Mineral

Property Rules or their predecessor rules under SEC Industry Guide 7 because it is a “foreign private issuer” under the Exchange Act

and entitled to file reports with the SEC under MJDS.

The SEC Mineral Property Rules include terms describing mineral reserves and mineral resources that are substantially similar, but not

always identical, to the corresponding terms under the CIM Definition Standards. The SEC Mineral Property Rules allow estimat es of

“measured”, “indicated” and “inferred” mineral resources. The SEC Mineral Property Rules’ definiti ons of “proven mineral reserve” and

“probable mineral reserve” are substantially similar to the corresponding CIM Definition Standards. Investors are cautioned t hat, while

these terms are substantially similar to definitions in the CIM Definition Standards , differences exist between the definitions under the

SEC Mineral Property Rules and the corresponding definitions in the CIM Definition Standards. Accordingly, there is no assurance any

mineral reserves or mineral resources that Skeena may report as “prov en mineral reserves”, “probable mineral reserves”, “measured

mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43 -101 would be the same had Skeena

prepared the mineral reserve or mineral resource estimates under the standards adopted under the SEC Mineral Property 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 economic 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 b e 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. fede ral

securities laws and the rules and regulations thereunder.
