SEABRIDGE GOLD ANNOUNCES SUCCESSFUL ENERGIZATION OF KSM PROJECT'S TREATY CREEK TERMINAL

Seabridge Gold Inc. is pleased that BC Hydro substantially completed and successfully energized the Treaty Creek terminal (TCT) on Aug. 27, 2026, a significant milestone in the development of infrastructure supporting the company's KSM project in northwestern British Columbia.

The terminal, located on Highway 37 approximately two kilometres north of the entrance to the KSM project, represents a key component of the electrical infrastructure required to support future construction and operations at KSM. The facility is expected to be ready for service by November, 2026.

Rudi Fronk, chair and chief executive officer of Seabridge Gold, stated: "The Treaty Creek terminal means KSM has access to reliable, clean and economic hydroelectric power which lowers KSM's carbon footprint and reduces its operating costs. We appreciate BC Hydro's continued commitment to supporting responsible resource development in northwestern British Columbia."

The KSM project is one of the world's largest undeveloped copper and gold projects held by a publicly traded company. The project can serve as a significant long-term source of critical minerals. To date, KSM has invested over $1.2-billion in responsibly advancing the project, a significant portion of which has been spent on local businesses and workers.
