    First Quantum’s Taca Taca report: trolley-assist haulage lens for mine planners

    First Quantum’s Taca Taca report: trolley-assist haulage lens for mine planners

    First reported on International Mining – News

    30 Second Briefing

    First Quantum Minerals has filed a new NI 43-101 Technical Report for its Taca Taca porphyry copper-gold-molybdenum project in Argentina’s Puna region, again incorporating the option of trolley-assist haulage for the open pit. The study continues to evaluate overhead electric trolley lines on key ramp segments to cut diesel consumption and unit costs for large ultra-class haul trucks. For mine planners and electrical engineers, the report signals ongoing commitment to high-capacity pit electrification rather than a purely diesel truck fleet.

    Technical Brief

    • Technical Report prepared under NI 43-101, effective date 31 December 2025, formalising current assumptions.

    Our Take

    Trolley-assist planning at the Taca Taca copper project aligns with other ‘green fleet’ moves in our database, such as Boliden’s European copper operations push (5 Dec 2025), signalling that large copper producers are starting to bake diesel-displacement infrastructure into base-case mine designs rather than treating it as an add-on.

    Copper dominates the 1804 keyword-matched pieces in our coverage, and trolley assist is emerging there as a preferred decarbonisation lever for high-altitude Puna-style operations where engine derating and haul-cycle penalties make the energy and productivity gains from overhead power particularly valuable.

    Deep Sea Minerals exploration licence: CCZ project implications for mine planners

    Deep Sea Minerals (CSE: SEAS), via its US subsidiary American Ocean Minerals Corp., has applied to NOAA for a DSHMRA exploration licence targeting polymetallic nodules in a defined tract of the Clarion-Clipperton Zone in the Pacific. The submission includes baseline environmental data, proposed monitoring and mitigation measures, and a phased exploration plan with specified expenditure commitments. NOAA has recently pledged extra resources to accelerate licence and permit reviews, following a 2025 US executive order promoting deep-sea mining for nickel, copper and manganese.

    Tivan’s Speewah fluorite project: MSP backing and mine planning notes for engineers

    Tivan Limited’s Speewah fluorite project in Western Australia has been selected as a priority initiative under the US–Japan–Australia Minerals Security Partnership, giving it access to coordinated government backing for critical minerals development. The project targets high-purity fluorite (fluorspar) suitable for aluminium smelting and battery materials supply chains, positioning it as a potential non-Chinese source of acid-grade concentrate. For geotechnical and mine planners, the designation signals likely acceleration of resource drilling, pit design and processing studies, with funding support tied to export-oriented offtake into US and Japanese markets.

    Kal Tire–Decoda haul road hazard tech: design and maintenance insights for mines

    Kal Tire’s Mining Tire Group has partnered with Australian mining technology firm Decoda to deploy a real-time haul road hazard detection system for large open-pit haul trucks. Using on-board sensors and analytics integrated with fleet management platforms, the system flags issues such as potholes, spillage, standing water and excessive grade or crossfall as trucks travel, rather than relying solely on periodic road inspections. The approach targets reduced tyre damage and unplanned downtime, and gives mine planners continuous data to prioritise road maintenance and adjust haul profiles.
