    Deep Sea Minerals enters CCZ: project model and timing explained for mine planners

    Deep Sea Minerals enters CCZ: project model and timing explained for mine planners

    First reported on MINING.com

    30 Second Briefing

    Deep Sea Minerals (CNSX: SEAS), newly rebranded from Copperhead Resources, is seeking exploration licences in the Clarion-Clipperton Zone and the Cook Islands’ EEZ, backed by an oversubscribed C$4.22 million private placement and a fresh NOAA application under the US Deep Seabed Hard Mineral Resources Act. CEO James Deckelman plans an asset-light model, contracting vessels and nodule collection systems rather than owning hardware, with initial work targeted for late 2026–early 2027. The move challenges early CCZ mover The Metals Company, whose areas cover under 5% of the zone’s polymetallic nodule field.

    Technical Brief

    • NOAA application is lodged under the US Deep Seabed Hard Mineral Resources Act (DSHMRA) framework.
    • Clarion-Clipperton Zone holdings of The Metals Company currently cover under 5% of the total nodule field.
    • CCZ prospective area extends across “millions of square kilometres” of abyssal plain seabed with polymetallic nodules.
    • Target commodities are nickel, cobalt, manganese and copper contained in unattached nodules lying on the ocean floor.
    • Planned operating model contracts vessels, nodule collectors and offshore services from existing providers instead of owning hardware.
    • Technology selection is ongoing, with multiple third-party nodule collection and sediment management systems under evaluation.
    • A senior exploration executive with prior deep-sea mining experience is being recruited to lead technical work programmes.
    • Environmental controls under consideration include more selective nodule pickup and plume-reduction strategies to limit benthic disturbance.

    Our Take

    Deep Sea Minerals’ NOAA application for polymetallic nodules in the Clarion-Clipperton Zone, noted in our 24 March 2026 coverage, positions it to compete directly with The Metals Company’s roughly 5% CCZ holdings rather than chasing fringe ground, which could compress the first-mover advantage TMC has been banking on.

    Regulatory changes under the Deep Seabed Hard Mineral Resources Act highlighted in our January 2026 article—merging exploration and commercial recovery steps under NOAA—mean that Deep Sea Minerals and TMC are effectively racing not just for CCZ tenure but for the first fully permitted US-aligned production window around the late‑2026/early‑2027 horizon mentioned here.

    Weir’s WARMAN MCR² mill circuit pump: reliability and wear-control notes for plant engineers

    Weir has introduced the WARMAN MCR² mill circuit pump as an evolution of its existing WARMAN mill circuit range, targeting mineral processing plants facing more complex ores, higher throughput and harsher slurry conditions. The MCR² is engineered to give operators tighter control over wear behaviour, maintenance intervals and overall asset condition in high-duty grinding circuits. For plant engineers, the new design signals further options to stabilise mill discharge pumping performance as ore hardness and variability increase.

    Tivan’s Walshy’s Wall drilling: subsurface targets and RC plan for mine planners

    Tivan has secured final regulatory and heritage approvals to start maiden drilling at the Walshy’s Wall target within the Sandover Fluorite Project in the Northern Territory, with a staged programme of 31 reverse circulation holes scheduled from October. Walshy’s Wall, a manganese–barite gossan discovered by Tivan geologists in October 2025, will be tested for subsurface continuity and grade using RC to penetrate the weathered profile efficiently. Early results will guide follow-up step-out drilling and resource definition across the broader fluorite–manganese system.

    Bellevue Gold board refresh: governance and project finance lens for mine teams

    Bellevue Gold is adding two independent non-executive directors, Debra Counsell and Tanya Rybarczyk, to its board from 23 September 2026 as part of a planned succession process for the Western Australian gold producer. Both bring more than 30 years’ experience spanning mining, resources, finance and infrastructure, signalling a stronger governance and capital markets focus as Bellevue ramps up its namesake underground operation. The appointments point to closer board scrutiny of project financing, risk management and long-term growth options in a volatile gold price environment.
