Skeena Provides Update on Near Term Value-Generating Catalysts

Vancouver, BC (July 18, 2023) Skeena Resources Limited (TSX: SKE, NYSE: SKE) (“Skeena” or

the “Company ”) is pleased to provide an update on several near-term catalysts expected to drive

growth at its 100% owned Eskay Creek and Snip Projects (the “Projects”) located in the Golden

Triangle of northwest British Columbia, Canada . This update is mainly focused on technical

optimization of the Projects, specifically related to exploration, metallurgy, and engineering studies.

Randy Reichert, Skeena’s President & CEO, commented “We anticipate 2023 to be a transformational

year for the Company as we progress from exploration and project studies into development. Skeena’s

primary focus is continued growth at both Projects through advancement o f engineering and

metallurgical optimization. Several near-term milestones are expected in the second half of this year

with a goal of growing the mine life and net present value of Eskay Creek, continuing to increase value

for all stakeholders.”

Table 1: Near Term Value-Generating Catalysts for Skeena

Catalyst Expected Completion Date

Updated Mineral Resource Estimate for Eskay Creek Completed Q2 2023

Increased Land Package Surrounding Eskay Creek Completed Q3 2023

Metallurgical Optimization & Simplified Flowsheet at Eskay Creek Expected Q3 2023

Updated Mineral Resource Estimate for Snip Expected Q3 2023

Exploration Results from Eskay Creek Expected Q3/Q4 2023

Definitive Feasibility Study for Eskay Creek Expected Q4 2023

Maiden Engineering Study for Snip Expected Q1 2024

Below highlights the details of the key technical updates in Table 1 that Skeena has recently completed

or expects to complete in the near-term at both Eskay Creek and Snip.

Updated Mineral Resource Estimate for Eskay Creek (completed Q2 2023)

Skeena published an updated Mineral Resource Update (“MRE” or “Resource”) for Eskay Creek on

June 20, 2023. This update highlighted a total increase of 8%, adding over 430,000 gold equivalent1

(“AuEq”) ounces to the MRE . With 7 3% of the Resource now being in the Measured and Indicated

categories the Company expects a large percentage to convert to Reserves, potentially adding a year

or more of mine life to Eskay Creek in the Q4 2023 Definitive Feasibility Study (“DFS”).

Increased Land Package Surrounding Eskay Creek (completed Q3 2023)

The Company recently increased its land package by acquiring five new claims surrounding Skeena’s

existing Eskay Creek and Eskay North claims. These new claims cover the interpreted northeastern

extension of the Eskay Creek Rift system, which has the potential to host additional minera lization.

1 AuEq in this release have factored metallurgical recoveries as per the calculation: AuEq = ((Au (g/t)*1700*0.84) + (Ag (g/t)*23*0.88))

/ (1700*0.84). US$1,700/oz Au, US$23/oz Ag, 84% gold recovery and 88% silver recovery.

NR: 23-16 | July 18, 2023

With a total land package now exceeding 100,000 hectares, the Company has one of the largest land

positions held for mining in the mineral-rich Golden Triangle region of British Columbia.

Metallurgical Optimization & Simplified Flowsheet at Eskay Creek (expected Q3 2023)

Following the 2022 Eskay Creek Feasibility Study (“FS”), Skeena has continued metallurgical test

work using representative samples of Eskay Creek material. The focus of this work has been to

simplify the process flowsheet and improve the quality of the concentrate expected to be produced

from the flotation plant. Recent testing has shown significant improvements in flotation concentrate

quality due to better flotation kinetics and employing a finer re -grind particle size distribution. The

Eskay Creek processing plant is now expected to be a traditional flotation plant with a single stage of

rougher flotation and a simple re -grind and flotation cleaning circuit. This change represents a likely

reduction in both process plant capital costs and operational costs. Gold recovery within the modified

process is expected to be comparable to the 2022 FS.

Updated MRE for Snip (expected Q3 2023)

Skeena plans to release an updated MRE for their Snip Project which will incorporate an additional

307 drillholes totaling 46,268 metres of drillin g. The majority of the new drilling was completed by

Hochschild Mining under their option agreement before Skeena r egained 100% ownership of the

project on April 5, 2023. The additional drilling is expected to expand and upgrade Inferred ounces to

the Indicated category.

Exploration Results from Eskay Creek (expected Q3/Q4 2023)

Three drills are currently operating at Eskay Creek, two of which are focused on the Eskay Deeps

target in search of high-grade mineralization hosted in the Contact Mudstone at depth and along strike

of the currently defined deposit. The third drill is f ocused on exploring for additional near mine

mineralization that may be amenable to open-pit mining in proximity to the already defined resources

at Eskay Creek. Assay results are expected to be released in fall 2023.

Skeena’s Senior Vice President of Exploration & Resource Development, Paul Geddes, commented

“Our thesis that the mineralized Eskay Creek Rift system continues at depth beyond the delineated

NEX Zone was proven in 2022 with drill hole SK-22-1081, which intersected 3.79 g/t Au, 59.4 g/t Ag

over 32.19 metres. This new occurrence is 650 metres down-dip of the current Resource and opens

up a substantial area of new exploration potential. We are excited for this new phase of exploration at

Eskay Deeps to test the true size potential of the Rift.”

Definitive Feasibility Study for Eskay Creek (expected Q4 2023)

The Company is progressing towards the completion of a DFS for Eskay Creek. The updates that will

be incorporated into th e Study include the recently update d MRE, metallurgical optimization ,

refinements to the mill flowsheet, updated capital expenditure figures, and modifications to the open-

pit mining method to enhance selectivit y and minimize dilution. Skeena anticipates these updates to

increase confidence in successful execution and extend the life of mine, ultimately increasing the value

of Eskay Creek.

Maiden Engineering Study for Snip (expected Q1 2024)

Following the completion of an updated MRE for Snip in Q3 2023 , Skeena will work to finalize an

engineering study on the project. Th e study will highlight Snip as a potential satellite operation ,

providing ore to a centralized mill at Eskay Creek. The Company expects the additional ore from Snip

to further bolster the mine life at Eskay Creek and increase payabilities of the concentrate.

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 Reserv es” adopted by the CIM Council (as amended, 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 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 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.
