Seabridge Gold’s US$100M KSM loan: design and permitting signals for mine planners

30 Second Briefing
Seabridge Gold has secured a US$100 million unsecured credit line at 7% interest, drawable in US$10 million tranches to year-end 2026, to fund roads, geotechnical, metallurgical and environmental data collection for feasibility-level design at its US$8.8 billion KSM gold-copper project in British Columbia’s Golden Triangle. The financing proceeds despite a B.C. Supreme Court order to redo Indigenous consultation on KSM’s “substantially started” status and a permitting standoff with Tudor Gold over the 12.5 km Mitchell Treaty Tunnels crossing Treaty Creek. KSM’s 2022 prefeasibility study reports 2.29 billion tonnes of proven and probable reserves grading 0.64 g/t gold and 0.14% copper, containing 47.3 million oz. gold and 7.3 billion lb. copper.
Technical Brief
- Credit line is unsecured, 7% interest compounded monthly, maturing 31 December (year not specified).
- Minimum US$10 million drawdowns allow staged mobilisation of seasonal field and access works.
- KSM lies ~270 km northwest of Terrace and ~950 km northwest of Vancouver in the Golden Triangle.
- B.C. Supreme Court ordered the Environmental Assessment Office to redo “substantially started” determination after inadequate Tsetsaut Skii km Lax Ha consultation.
- B.C. is withholding amendments for the 12.5 km Mitchell Treaty Tunnels route until Seabridge–Tudor Gold resolve alignment dispute.
- Seabridge reports ~US$1.2 billion invested at KSM since 2001, including >US$200 million in permanent works since January 2024.
- 2022 prefeasibility reserves include 160 million oz silver in addition to gold and copper inventory.
- If unpaid at maturity, loan may be repaid in cash or common shares, subject to TSX approval.
Our Take
The BC Supreme Court’s order to reopen the Environmental Assessment Office’s “substantial start” decision for KSM (10 June 2026 item) means this US$8.8 billion gold-copper project in northwest B.C. is now advancing financing while its long-term environmental approval clock is effectively back under review, which can complicate lender risk assessments even with a secured credit line.
The earlier pause on permitting for the C$6.4 billion Mitchell Treaty Tunnels (12 April 2026 article) underscores that this 12.5 km tunnel section is not just an engineering feature but a regulatory choke point: any further disputes with Tudor Gold or over Treaty Creek access could stall physical works that Seabridge needs to demonstrate “substantial start” and protect the KSM approvals window.
