Press Release

Vancouver, BC (December 15, 2025) Skeena Resources Limited (TSX: SKE, NYSE: SKE) (“Skeena Gold & Silver”, “Skeena” or the “Company”) is pleased to announce that the Tahltan Nation has voted in support of the Impact Benefit Agreement (“IBA”) in relation to the development and future operation of Skeena’s 100%-owned Eskay Creek Gold-Silver Project (“Eskay” or the “Project”).

In a referendum vote among its membership, the Tahltan Nation voted in favor of the proposed Impact Benefits Agreement in relation to the Eskay Creek Project. A decision from the Tahltan Central Government Board of Directors regarding consent to the Eskay Creek Project will be under consideration in January 2026.

The IBA establishes a framework that ensures shared benefits, including:

• Employment and business opportunities for Tahltan members and companies;
• Training and education initiatives to build long-term capacity;
• Funding for a facility to benefit Tahltan elders; and
• Meaningful financial participation in the Eskay Creek Project.

Walter Coles, Executive Chairman of Skeena, commented: “We extend our sincere appreciation to the leadership of the Tahltan Central Government, Tahltan Band, and Iskut Band for trusting Skeena to advance Eskay Creek. The ratification of this IBA reflects the hard work we have achieved together. This innovative agreement sets new industry standards for First Nation involvement in environmental protection and sharing of benefits from the Project.”

Justin Himmelright, Senior Vice President of External Affairs, commented: “We see the IBA as the foundation for a long-term, meaningful partnership between Eskay Creek and the Tahltan Nation. Over the years, the Tahltan Nation has played a key role in shaping the direction of the project. They have shared their environmental, cultural, and economic priorities and we have worked together to ensure those values are reflected in the Project.”
