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

    First reported on International Mining – News

    30 Second Briefing

    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.

    Technical Brief

    • Cementation Africa is targeting multi-year shaft sinking and underground development contracts across deep-level operations.
    • Group CFO Sibulele Songca stresses contract structures that align payment profiles with long mobilisation and development phases.
    • Cash-flow modelling is being used to map contractor funding requirements over entire shaft sinking and ramp-up periods.
    • Governance frameworks are being formalised to handle complex audit trails, cost tracking and change-order management on long contracts.
    • Risk-sharing mechanisms are being negotiated to allocate schedule and cost overrun exposure between owner and contractor.
    • Contract mining offerings are being configured for high upfront capital exposure before steady-state production is achieved.
    • Internal project controls are being strengthened to manage multi-year commitments under stringent ESG and reporting obligations.
    • For similar deep underground mining projects, robust financial and governance capacity is becoming a precondition to tender.

    Our Take

    Cementation Africa appears frequently in our mining project coverage without commodity tags, signalling that its current contract mining push is largely service- and method-driven rather than tied to a single ore type or region.

    The recent Mindola shaft upgrade work for Mopani Copper Mines and Tharisa’s transition to underground at its chrome–PGM operation suggest Cementation Africa is positioning as a go-to contractor for complex brownfield underground conversions rather than only greenfield sinks.

    The strategic ownership transition involving Cementation Africa, Cementation Americas and Terra Nova Technologies earlier in 2026 indicates that any new underground contract mining commitments will likely be backed by a broader group balance sheet and shared technical platforms across continents.

    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.

    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.

    Paus–VirtuRail battery-electric rail systems: logistics design notes for mine engineers

    Paus has acquired a stake in Austrian firm VirtuRail, adding battery-electric drive systems, intelligent vehicle control and automation to its underground and construction logistics portfolio. The deal positions Paus as a development and manufacturing partner for VirtuRail’s rail-based logistics platforms, integrating electric traction packages with digitally controlled haulage. For mine operators, this signals more OEM-backed options for battery-electric materials handling and automated logistics trains in constrained headings and construction sites.
