    Tactical Resources’ Nasdaq move and Texas REE tailings: key points for mine planners

    Tactical Resources’ Nasdaq move and Texas REE tailings: key points for mine planners

    First reported on MINING.com

    30 Second Briefing

    Tactical Resources is pursuing a Nasdaq listing via a SPAC merger with Plum Acquisition Corp. III as it advances the Peak rare earths project in West Texas, built around ~4 million tonnes of REE-bearing tailings at the Sierra Blanca quarry. The company has now acquired the underlying quarry, including land, mineral rights, existing power, water, rail and crushing infrastructure, enabling a feedstock-first strategy with no new mining or primary permits. Development centres on a pilot and then modular demonstration plant for direct-leach extraction and separation of heavy rare earths such as dysprosium, terbium and yttrium.

    Technical Brief

    • Tactical now owns the quarry land, mineral rights, equipment and stockpiled material outright (100% control).
    • Stockpiles generated over more than 20 years of railway ballast production are interpreted as REE-enriched.
    • Approximately four million tonnes of tailings are expected to underpin at least five years of initial throughput.
    • Direct-leach amenability of the hard-rock material allows bypassing several conventional rare earth beneficiation stages.
    • Development sequence runs pilot plant → on-site demonstration plant → modular scale-up, aligned with staged offtake contracting.
    • Heavy REE focus (Dy, Tb, Y) targets magnet and defence supply chains prioritised in recent US policy support.

    Our Take

    Rare earths pieces in our database that involve existing stockpiled material, like the 4 million tonnes of REE-bearing tailings at the Sierra Blanca quarry, typically move faster through early permitting because they are framed as waste reprocessing rather than greenfield mining.

    Texas-linked rare earths and critical minerals items in our coverage often sit alongside national security narratives, so a Nasdaq listing for Tactical Resources would likely help position The Peak project as a US-aligned alternative to Congo- and China-exposed supply chains for dysprosium, terbium and yttrium.

    With tailings alone expected to support about five years of operations, Tactical Resources can refine its flowsheet and offtake strategy before committing to full-scale primary mining, a sequencing approach that has reduced ramp-up risk at other US critical minerals projects in our database.

    LGMG ultra-fast charging battery mining trucks: haulage and power notes for engineers

    LGMG has unveiled an ultra-fast charging battery mining truck solution aimed at China’s ‘Dual Carbon’ strategy, targeting haul fleets where low charging efficiency and costly fixed infrastructure have stalled pure-electric adoption. The system is designed for high-power, short-duration charging cycles compatible with large rigid and articulated trucks, reducing idle time compared with conventional overnight or multi-hour charging. For mine operators, the approach enables higher utilisation of existing pits and haul roads without extensive substation upgrades, while cutting diesel-related ventilation and emissions constraints in deep or enclosed operations.

    Cementation Africa underground contracts: risk, ESG and balance sheet lens for engineers

    Mining companies awarding multi-year shaft sinking and underground development contracts are now prioritising contractors’ balance sheet strength and governance frameworks alongside technical capability, says Cementation Group CFO Sibulele Songca. For deep-level projects with high upfront capital exposure, owners are scrutinising contractors’ ability to absorb schedule risk, manage cash flow over extended mobilisation periods, and comply with stringent ESG and audit requirements. This shift favours larger, well-capitalised underground specialists like Cementation Africa for long-duration, high-risk contract mining commitments.

    Thiess–FLANDERS hybrid retrofit programme: haul truck design notes for mine engineers

    Thiess has signed a partnership and distribution agreement with FLANDERS to roll out FLANDERS’ hybrid retrofit drive train technology on existing mechanical‑drive haul trucks, rather than waiting for new battery‑electric fleets. The deal leverages Thiess’ global asset maintenance capability, engineering teams, rebuild workshops and field delivery experience to integrate the hybrid systems across its operating regions. For mine operators, the programme offers a pathway to cut diesel use and emissions on current truck fleets without major pit reconfiguration or new OEM platforms.
