    Antimony Resources’ Bald Hill: exploration strategy and supply risk notes for engineers

    Antimony Resources’ Bald Hill: exploration strategy and supply risk notes for engineers

    First reported on MINING.com

    30 Second Briefing

    Antimony Resources Corp has exposed additional “massive” stibnite mineralisation in bedrock at the Marcus West Zone of its Bald Hill project in New Brunswick, and will immediately drill up to six shallow holes to test the zone at 30–50 m depth alongside a 10,000 m definition drilling campaign on the Main Zone. Historic trenching in the Central Zone returned 2.90% Sb over 8.18 m, including 5.79% Sb over 1.75 m and 8.47% Sb over 1.53 m, while ATMY trenching has traced South Zone stibnite over ~150 m. The 2026 programme also includes soil sampling, prospecting, and a potential airborne survey, positioning Bald Hill as a North American antimony target amid Chinese export controls.

    Technical Brief

    • Field crews are mechanically trenching into bedrock at Marcus West to expose in-situ stibnite.
    • Excavator-exposed “bladed” stibnite textures suggest coarse, visually distinguishable mineralisation aiding rapid field logging.
    • Sampling of newly exposed Marcus West bedrock is ongoing to extend mineralisation definition along strike.
    • Unexplored Central Zone trench data from 2010 provide 2.90% Sb over 8.18 m as a key follow-up target.
    • South Zone trenching by ATMY has already mapped surface stibnite continuity over roughly 150 m.
    • A second drill rig has been mobilised to accelerate Main Zone definition drilling progress.
    • 2026 work programme integrates trenching, drilling, soil sampling, prospecting and potential airborne geophysics for 3D targeting.
    • China’s September 2024 antimony export controls are driving renewed Canadian and US exploration focus on Sb deposits.

    Our Take

    Antimony appears in only a small subset of our 1,090 Mining stories, so Bald Hill in New Brunswick stands out as one of relatively few advanced antimony–stibnite plays in North America at a time when China’s September 2024 export controls are tightening supply options.

    The combination of antimony with rare earth elements such as neodymium and praseodymium at the Bald Hill property aligns with other critical-mineral stories in our database where multi-commodity critical metal packages are being favoured by North American policymakers and potential strategic investors.

    Historic trench grades above 5% Sb over metre-scale intervals at the Central Zone suggest that, if continuity is confirmed by the planned 30–50 m drilling at Marcus West, Bald Hill could be evaluated as a relatively small-footprint, high-grade underground or selective open-pit operation, which is typically easier to permit in Canada’s Atlantic provinces than large bulk-tonnage projects.

    Boliden Somincor–EDP–Greenvolt solar UPAC: integration notes for Neves‑Corvo mine engineers

    Boliden Somincor has partnered with EDP and Greenvolt to build Portugal’s largest self‑consumption solar generation unit (UPAC) near the Neves‑Corvo zinc mine at Castro Verde, supplying power directly to mine operations. The distributed solar plant will sit adjacent to one of Europe’s largest zinc orebodies, reducing grid dependence for high‑load processes such as hoisting, ventilation and paste backfill plants. For mine planners and electrical engineers, the project signals growing integration of large‑scale on‑site renewables into base‑metal underground operations in southern Europe.

    Aramine AutoNav Tele loader at Reward Gold mine: design and safety notes for planners

    RCT – Powered by Epiroc’s AutoNav Tele automation has been fitted to an Aramine L350D loader to support narrow vein stoping at Vertex Minerals’ Reward Gold mine at Hill End, after the unit was commissioned through Epiroc’s Orange Service Centre in New South Wales. The compact L350D, designed for ultra-narrow headings, is now operated via tele-remote AutoNav control rather than line-of-sight, allowing tramming and loading in constrained drives. For geotechnical and mine planners, this enables extraction in thinner ore lenses while keeping operators out of unsupported ground.

    Bosch Rexroth–MEDATech off‑highway electrification: integration notes for mine engineers

    Bosch Rexroth is partnering with MEDATech Engineering to deliver end‑to‑end electrification packages for off‑highway and mining mobile equipment, combining Rexroth’s mobile hydraulics, inverters and controls with MEDATech’s EV drivetrain integration capability. The collaboration targets full systems from componentry and software through to application‑specific design and build, aimed at OEMs and retrofit projects for haul trucks, loaders and other heavy units. For mine operators, this points to more standardised electric powertrain architectures and a clearer route to integrating high‑voltage drivetrains with existing hydraulic and control systems.
