    US DOE funds MIT drill core tech: assay speed and targeting insights for mine teams

    US DOE funds MIT drill core tech: assay speed and targeting insights for mine teams

    First reported on MINING.com

    30 Second Briefing

    US DOE’s ARPA‑E ROCKS programme has selected Fieldstone Bio, TerraCore and MIT to build a field‑deployable system that maps critical minerals directly on drill core, delivering quantitative, core‑length metal distributions in hours instead of weeks. The method combines engineered microbial sensors, tuned to emit distinct signals for metals such as gold, copper, molybdenum and arsenic at parts‑per‑billion sensitivity, with compact hyperspectral imaging cameras already used in core logging. Scout Discoveries will supply active Western US drill sites and fresh core to validate performance, with the sensor library to be expanded to rare earths and nickel.

    Technical Brief

    • Engineered microbial biosensors are applied directly to core surfaces within standard core-handling workflows, avoiding environmental release.
    • Microbes emit distinct optical reporter signals on metal binding, which are captured by compact hyperspectral imaging (HSI) cameras.
    • Fieldstone’s imaging and analysis system converts HSI-detected biosensor signals into quantitative, high-resolution metal distribution maps along full core length.
    • Laboratory methods referenced for comparison include fire assay and ICP‑MS, both requiring off-site shipment and lab queue times.
    • Research foundation comes from Dr Christopher Voigt’s MIT lab, where reporter constructs were engineered to be readable by HSI at stand‑off distances and published in Nature Biotechnology.
    • Fieldstone has already demonstrated biosensors for gold, copper, molybdenum and arsenic with parts‑per‑billion detection sensitivity in controlled tests.
    • Under the ARPA‑E ROCKS programme, Fieldstone will extend the sensor library to cover rare earth elements and nickel and validate performance on freshly extracted cores with TerraCore and Scout Discoveries at active Western US drill sites.
    • Scope is currently limited to core samples treated in controlled workflows; no details are given on calibration against certified reference materials, long‑term sensor stability, or regulatory acceptance as an assay replacement.

    Our Take

    Critical minerals pieces in our database that mention the USA often focus on permitting or downstream processing, so a U.S. Department of Energy and ARPA‑E backed core‑analysis technology signals more attention moving upstream into exploration efficiency rather than just refining and recycling.

    The explicit reference to Congo in a U.S. critical minerals context mirrors other items in our database where American funding is tied to reducing exposure to Congolese cobalt, implying that technologies like this may become a soft requirement for demonstrating diversified, lower‑risk supply chains to U.S. policymakers and OEMs.

    Cemex and sensmore’s Rüdersdorf quarry: AI haulage lessons for mine planners

    Cemex and Berlin-based startup sensmore are digitising operations at the 770-year-old Rüdersdorf limestone quarry in Germany using AI-based loading and haulage optimisation. On-board edge devices and radar sensors on wheel loaders and haul trucks feed real-time data into sensmore’s optimisation engine, which recommends bucket fill levels, truck–loader pairing and haul speeds. Early results show reduced idle times and more consistent crusher feed, signalling practical pathways to retrofit AI-driven dispatch and loading control into existing European quarry fleets without full autonomy.

    Multotec spirals at Thaba JV: modular gravity circuit lessons for plant designers

    Multotec has supplied a customised suite of high-performance spiral concentrators to the Thaba JV chromite and PGM project in South Africa’s Limpopo province, providing an integrated gravity separation circuit tailored to the ore’s specific mineralogy. The solution is engineered to boost chromite and PGM recovery while tightening product grade control, with spiral configurations selected to allow rapid reconfiguration between different feed conditions and product specs. For plant designers and metallurgists, the key point is the emphasis on modular, flexible spiral layouts to sustain long-term performance as ore characteristics change.

    Antofagasta copper ramp-up to 2030: design and risk notes for mine engineers

    Antofagasta plans to lift copper output by 30% by 2030, Executive Chairman and CEO Iván Arriagada told delegates at the World Mining Congress 2026, positioning the Chilean producer to meet surging critical minerals demand from the energy transition. The growth will come from brownfield expansions across its existing operations rather than new greenfield projects, implying higher stripping ratios, additional concentrator capacity and incremental tailings and water management upgrades. For engineers, the strategy signals sustained demand for large-scale pit optimisation, process debottlenecking and infrastructure life-extension work in northern Chile.
