    CSIRO farm trials on low-frequency mining links: key takeaways for engineers

    First reported on Australian Mining

    30 Second Briefing

    CSIRO is running farm-based trials to test low-frequency wireless signals for use in underground and remote mining connectivity, targeting conditions where conventional Wi-Fi and LTE struggle with rock mass attenuation and long drifts. Researchers are assessing signal penetration through soil and vegetation, antenna configurations, and power requirements to understand how similar systems could maintain links to autonomous trucks and sensors in deep headings and block caves. Early results will inform network design choices for mines seeking robust, low-bandwidth control and monitoring channels alongside existing high-frequency systems.

    Technical Brief

    • Outcomes are intended to inform redundancy planning and fail‑safe communication layers for autonomous and remote mining systems.

    Our Take

    CSIRO’s work on low‑frequency connectivity in Australia sits alongside its petalite and low‑emissions mining research in our database, signalling that the organisation is building a vertically integrated digital-and-processing toolkit rather than treating communications as a standalone IT issue.

    Across the 1099 Mining stories in our coverage, very few research-tagged pieces deal with sub‑GHz or low‑frequency networks, so these farm trials could give Australian operators an early playbook for linking remote sensors and equipment without relying on dense 5G or Wi‑Fi infrastructure.

    For Australian Mining readers, this kind of CSIRO-led connectivity research typically precedes pilot deployments with METS suppliers, so practitioners looking at autonomous or remote operations may want to track which vendors align early with CSIRO’s preferred low‑frequency architectures.

    MAX Power Mining–Moose Jaw hydrogen MOU: subsurface and capex notes for engineers

    MAX Power Mining has signed an MOU with the City of Moose Jaw, Saskatchewan, to advance natural hydrogen commercialisation in the Regina–Moose Jaw Industrial Corridor, centred on the Lawson Natural Hydrogen system near Central Butte, about 80 km northwest of the city. Core desorption tests from nine samples in Cambrian Basal sands above the Basement Complex discovery returned helium values up to 8.7%, averaging 4.4%, indicating a potentially valuable hydrogen–helium system. The partners aim to leverage existing regional infrastructure and policy support to move the project towards commercial validation.

    Water shortages and mining projects: schedule and design takeaways for engineers

    Water scarcity and multi‑year permitting delays—often two to four years for discharge and dewatering approvals in the western US—are increasingly stalling otherwise bankable mines, with water risk now affecting project schedules, financing and national credit profiles. Consultants such as Woodard & Curran report that “credible water stories” are becoming as critical as ore grades, pushing operators towards closed‑loop recycling and non‑traditional sources. US firms Genesis Systems and Atoco are deploying atmospheric water generation units, including Genesis’ containerised WaterCube systems producing over 1,000 gallons per day off‑grid, now trialled at mine sites.

    Nouveau Monde’s Matawinie graphite mine: capex, schedule and offtake lens for engineers

    Nouveau Monde Graphite has approved construction of the Matawinie open-pit mine in Saint-Michel-des-Saints, Quebec, designed to produce about 106,000 tonnes per year of graphite concentrate over more than 25 years and powered by the provincial hydroelectric grid. The company has secured roughly $644.5 million in equity and debt, with total capex for Matawinie and the Bécancour battery material plant now estimated at about $634 million after downsizing the plant from the 2025 feasibility study. A 30‑month build is planned to reach full production by end‑2028, with 75% of output under offtake, including a seven‑year, 30,000‑t/y fixed‑price contract with the Government of Canada.
