    MACA’s Okvau gold mine extension to 2030: planning signals for mine engineers

    September 29, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    MACA has secured a A$170 million, two-year contract extension with Emerald Resources to continue mining operations at the Okvau gold mine in Cambodia, taking the engagement through to February 2030. The scope covers full open-pit production services, including mine development, drill-and-blast, overburden stripping, ore mining and on-site mining support. For contractors and mine planners, the long-term commitment signals stable demand for production drilling, blasting consumables and fleet deployment strategies in a relatively new gold jurisdiction.

    Technical Brief

    • Contract extension value of A$170 million provides defined mining services revenue for MACA’s Cambodia operations.
    • Two-year term allows medium-term mine scheduling and fleet replacement planning aligned with Okvau pit development.
    • Scope bundling of drill-and-blast, overburden and ore mining centralises operational control under a single contractor.
    • Inclusion of “associated mining support” implies MACA responsibility for ancillary services such as haul road and ROM management.
    • Continuity of one contractor over multiple years reduces interface risk between mine development and production phases.

    Our Take

    In our database of gold project pieces, MACA’s recent work with Liebherr dozers at Regis Resources’ Duketon and its role in Thiess’ AHS trial at Norton Gold Fields suggest that Okvau could benefit indirectly from MACA’s growing fleet standardisation and autonomy experience, even in a relatively remote jurisdiction like Cambodia.

    Trump’s Venezuela gold push: due‑diligence bottlenecks explained for mine teams

    Hundreds of millions of dollars’ worth of Venezuelan gold flown into the US under a Trafigura–Minerven deal backed by President Trump and Interior Secretary Doug Burgum is sitting idle because refiners refuse to process it without proof it meets responsible-sourcing standards. The gold, including about $100 million shipped within hours of the March signing, comes from guarded Minerven underground mines where small-scale producers reportedly pay protection money to the Tren de Guayana gang. Similar deals by Heeney Capital and Mercuria, targeting up to $2.2 billion a year in Venezuelan mineral exports, face the same due‑diligence bottleneck.

    Mining Forum: Friedland’s I-ROX comminution push – energy and recovery lens for engineers

    Robert Friedland is pushing to replace conventional SAG and ball mills with I-Pulse’s I-ROX pulsed-power comminution, which stores electricity then releases nanosecond–microsecond bursts to fracture ore internally along mineral boundaries, with projected energy cuts of up to 80% and about 5% higher metal recoveries. A 2,500 m² I-ROX research centre in Toulouse is testing Kamoa-Kakula copper ore and tailings, while I-Pulse has also secured a US$250 million CHIPS Act award for silicon-carbide semiconductors. The same platform underlies G-Pulse drilling, claimed to triple penetration rates and extend bit life sixfold, to be trialled on the Millungera Basin geothermal project in Queensland.

    Lake Resources’ Kachi lithium project: DIA approval and FEED lens for engineers

    Lake Resources has secured the key Environmental Impact Declaration for its Kachi lithium brine project in Catamarca, Argentina, clearing the project to enter front-end engineering design for a 25,000 tpa lithium carbonate equivalent facility using Lilac Solutions’ direct lithium extraction process and prior engineering work with Hatch. The DIA confirms compliance with provincial environmental and social standards, imposes a 200 m surficial exclusion zone around the lagoon shoreline, and sets pre‑operations obligations. Lake has also committed $1 million to Catamarca’s Mining Royalty Trust Fund, to be paid between October 2026 and June 2027 for local infrastructure.
