Skeena Commences Pre-Feasibility Study For Eskay Creek

Vancouver, BC ( June 15, 20 20) Skeena Resources Limited (TSX.V: SKE, OTCQX: SKREF)

(“Skeena” or the “Company”) is pleased to announce the commencement of a Preliminary Feasibility

Study (“PFS”) for the Eskay Creek gold-silver project (“Eskay Creek”) located in the Golden Triangle

of northwest British Columbia. The goal of the PFS is to technically further de-risk Eskay Creek while

developing an appropriate execution strategy to ensure fast tracked development towards commercial

production.

Given the success of the team that developed the Preliminary Economic Assessment (“PEA”) study

for Eskay Creek, Skeena will once again partner with Ausenco Engineering Canada Inc. (“Ausenco”),

SRK Consulting (“SRK”), and AGP Mini ng Consultants (“AGP”) to complete the PFS. The t arget

completion date for the PFS is summer 2021.

Shane Williams, Skeena’s new Chief Operating Officer commented, “ I am very excited to be joining

the Skeena team at this transitional stage in the Company’s history. The PFS is the next step in the

evolution of Eskay Creek as we move this high -grade, open -pit project towards development and

through to commercial production.”

PFS Work Program

A key work program as part of the development of the PFS will be an extensive infill drilling program

to convert a large portion of the Inferred resources into the Measured & Indicated category and

following completion of the PFS, declare maiden reserves for Eskay Creek.

Following the completion of the Eskay Creek PEA in 2019, several areas were identified that could be

optimized and enhanced with further work. This includes optimizing the metallurgy and the concentrate

quality and to better optimize the flow sheet. This work will further enhance the consistency and value

of the final concentrate produced allowing for key concentrate offtake discussion s to begin. Another

focus area will be to gain a better understanding of the geotechnical characteristics in the open-pit

which will allow for further pit optimization studies. Preparations and planning for these

work programs are ongoing.

Subject to the agreement with Barrick, upon exercise of the option to acquire a 100%-interest in Eskay

Creek (by December 2020), the Com pany will enter the permitting process for the expanded Eskay

Creek project. Skeena has already begun the comprehensive environmental studies that are required

for permitting and has initiated community engagement and consultation with Indigenous Nations .

Skeena has developed a comprehensive environmental program designed to fill identified historical

data gaps and to enhance existing data to meet current standards. Rescan Tahltan Environmental

Consultants (RTEC), a subsidiary of ERM, has been engaged to carry out the environmental studies.
