"Vancouver, BC (January 17, 2023) Skeena Resources Limited (TSX: SKE, NYSE: SKE) (“Skeena” or the “Company”) is pleased to announce the signing of the permitting Process Charter and other key milestones in the approval process for the Eskay Creek gold-silver Project (“Eskay Creek” or the “Project”) located in Tahltan Territory in the Golden Triangle of British Columbia (“BC”).

The Process Charter is a unique collaboration between Skeena, the Tahltan Central Government (“TCG”), and the Government of BC (the “Province”). This document establishes a workplan for all parties to collaborate on an efficient Environmental Assessment (“EA”) and permitting process for Eskay Creek. The target timelines established in the Process Charter outline the EA Certificate being received in H2 2024 and final permits to be issued in H1 2025. These dates align with the development timeline anticipated for the Project.

Connor Pritty, TCG Lands Director commented, “The TCG recently finalized the Process Charter for Eskay Creek. This document focuses on the details of regulatory processes related to the Project. It is an example of how Skeena is continually working with the Tahltan Nation to redefine how project approval processes are carried out within our Territory. We are working together to effectively integrate Tahltan knowledge, process requirements and decision-making specific to Eskay Creek. The TCG Lands Department looks forward to continuing to work with the team at Skeena.”

Skeena’s President & CEO, Randy Reichert, goes on to comment “The Process Charter is a significant step forward in the approval process for Eskay Creek. The signing of this document demonstrates the commitment from all parties on permitting the Project in an efficient and timely matter. We appreciate the efforts and collaboration shown by both the TCG and the Province in achieving this major milestone.”

Environmental Assessment Update - Readiness Decision & Federal Substitution
Skeena has worked closely with the TCG, Federal and Provincial regulators, Indigenous Nations, and communities to advance the EA process for Eskay Creek. On November 18, 2022, both the EA Office and TCG provided a positive Readiness Decision for the Project which advanced it to the Process Planning stage. Then, on November 29, 2022, the Federal Minister of Environment and Climate Change approved the substitution of the impact assessment to the BC Environmental Assessment Office (“BCEAO”). The substitution decision means that instead of doing two separate assessments on Eskay Creek, the BCEAO conducts a single assessment that meets both Provincial and Federal requirements.
