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

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

    First reported on MINING.com

    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.

    Central banks double gold-buying pace: price and project signals for mine planners

    Central banks have doubled their gold purchases to an average 1,000 tonnes per year over the past four years, with a World Gold Council survey of 76 institutions showing 89% expect global official holdings to rise and 45% plan to add to their own reserves. Speaking at the Rule Symposium in Boca Raton, senior market strategist Joseph Cavatoni framed the move as a structural response to sanctions, inflation and credit risk in paper currencies. The deeper, policy-driven demand base could underpin bullion prices, but miners still need to convert higher prices into disciplined production, cash flow and managed political and operating risk.

    Tactical Resources’ Nasdaq move: tailings-first Texas REE project lens for engineers

    Tactical Resources has secured Nasdaq Capital Market approval via a SPAC merger with Plum Acquisition Corp. III, with New PubCo shares to trade under the ticker “TREO” after the expected 28 July 2026 closing. The company plans to use the listing to accelerate its Peak rare earths project in Hudspeth County, Texas, which holds exclusive rights over about 4 million tonnes of REE-bearing tailings and stockpiles from the Sierra Blanca quarry and already has initial quarry operating permits. Tactical’s feedstock-first model relies on existing mined material, aiming to bypass new mine development and move directly into processing.

    Copper price surge on China demand, Chile losses: key signals for mine planners

    Copper climbed 1.3% on Comex to $6.35/lb (just under $14,000/t), within 5% of its early-June record, as China’s import premium hit $100/t for the first time since May 2025 and Shanghai exchange stocks fell 20% last week to 79,909 t, down 45% year-to-date. Tightness is being driven by Beijing’s VAT crackdown on the “invoice economy”, pushing substitution from scrap into cathode and drawing metal out of LME warehouses despite record 630,293 t in Comex storage. On the supply side, storms cut South32’s payable output at Sierra Gorda to 16,000 t for the June quarter, Antofagasta’s H1 production dropped 9.5% to 285,000 t with cash costs guided up to $2.40–$2.60/lb, and Codelco halted surface operations at Andina and shipments from El Teniente.
