    Excellon’s deeper gold-silver push at Mallay mine: restart design notes for engineers

    Excellon’s deeper gold-silver push at Mallay mine: restart design notes for engineers

    First reported on MINING.com

    30 Second Briefing

    Excellon Resources is targeting deeper gold-silver mineralisation at the past-producing Mallay underground mine in Peru, where historical output focused on silver-lead-zinc veins. A new technical report outlines potential at depth below existing workings and along strike of the Mallay and Manto Santa Elena structures, supporting a possible restart scenario. For mine planners and geotechs, the shift to deeper targets implies renewed underground development, updated ground control in previously mined areas, and re-evaluation of shaft, hoisting, and ventilation capacity for a gold-silver focused operation.

    Technical Brief

    • Restart case must account for legacy voids, remnant pillars and potential stress redistribution around old stopes.
    • Existing shaft, ramps and ventilation raises require condition assessment for corrosion, deformation and rockfall hazards.
    • Tailings and waste rock facilities from prior operations present options for re-use or expansion, subject to stability checks.
    • For similar brownfield underground projects, re‑using legacy infrastructure can cut capex but increases geotechnical uncertainty.

    Our Take

    Peru appears relatively under-represented in our recent Mining project coverage compared with jurisdictions like Canada and Australia, so deeper exploration at the Mallay mine may signal renewed interest in Andean underground gold–silver systems rather than greenfield plays.

    Most of the 26 keyword-matched gold and silver pieces in our database focus on single-commodity optimisation, whereas Mallay’s gold–silver–lead–zinc mix implies more complex metallurgy and offers optionality to pivot revenue streams as individual metal prices move.

    For Canadian operators active in Peru, such as at the Mallay mine, our coverage suggests permitting and community engagement timelines have been more predictable for brownfield underground work than for new open-pit proposals, which can influence how aggressively they pursue deeper resource targets.

    Equinox sells Brazilian operations to CMOC: portfolio and capex shift for mine planners

    Equinox Gold has agreed to sell its entire Brazilian portfolio — the Aurizona and RDM mines plus the Bahia complex (Fazenda and Santa Luz) — to China’s CMOC Group for over US$1 billion, including US$900 million cash on closing and up to US$115 million in contingent payments tied to production. The divested assets were guided to produce 250,000–270,000 oz. of gold in 2025, while Equinox’s refocused portfolio will centre on the Greenstone (220,000–260,000 oz.), Valentine (175,000–200,000 oz. at full run-rate) and Mesquite (85,000–95,000 oz.) operations. Proceeds will be used to retire US$800 million of debt, cutting interest costs and freeing capital for expansions at Valentine, Castle Mountain and Los Filos, with group output targeted at 700,000–800,000 oz. next year.

    Silicon Ridge critical minerals in Utah: grade, flowsheet and capex notes for engineers

    Ionic Mineral Technologies reports its Silicon Ridge project in Utah is a halloysite-hosted ion-adsorption clay system grading about 2,700 ppm (0.27%) combined rare earths and critical metals from 106 boreholes over 10,000 m and 35 trenches across 650 acres, exceeding typical Chinese IAC grades of 500–2,000 ppm. The confirmed mineralisation currently covers only 11% of the resource area to 100 ft depth, with existing mining permits and a 74,000 ft² Provo processing plant enabling rapid start-up. Ionic MT plans a vertically integrated flowsheet producing three co-product streams—critical minerals (including gallium, germanium, scandium, lithium and tungsten), high-purity alumina and nano-silicon—with a preliminary economic assessment due in H1 2026.

    Metso Geminex™ digital twins: control and reliability insights for plant engineers

    Metso is promoting its Geminex™ digital twin platform as a way to move mineral processing plant control beyond traditional DCS screens towards predictive and proactive maintenance. Geminex™ integrates real-time sensor data with dynamic process models of grinding, flotation and filtration circuits to simulate plant behaviour, test “what‑if” scenarios and optimise setpoints before implementation. For operators, this signals deeper use of virtual commissioning, remote performance tuning and model-based failure prediction across comminution and concentrator lines.
