    Deep Yellow’s new CEO from Rio Tinto: project development lens for mine planners

    Deep Yellow’s new CEO from Rio Tinto: project development lens for mine planners

    First reported on Australian Mining

    30 Second Briefing

    Deep Yellow has appointed former Rio Tinto uranium executive Greg Field as its new managing director and chief executive officer, signalling a leadership shift as it advances the Tumas project in Namibia and the Mulga Rock project in Western Australia. Field previously held senior roles in Rio Tinto’s uranium portfolio, including work on large-scale operations such as Ranger and Jabiluka, bringing direct experience in permitting, long-life open-pit design and yellowcake export logistics. His appointment points to a stronger development push on Deep Yellow’s multi-deposit pipeline as uranium prices remain elevated.

    Technical Brief

    • Governance-wise, combining managing director and CEO roles centralises accountability for project delivery and cost control.

    Our Take

    Deep Yellow is one of relatively few Australia-based names in our 279 tag-matched ‘Projects’ and ‘Contract Award’ pieces, where majors like Rio Tinto and BHP dominate, so importing Rio Tinto experience into its leadership signals an ambition to play at larger project scale and complexity.

    In our recent Australia-focused Mining coverage, leadership changes tied to project-delivery backgrounds have often preceded shifts in contracting strategy and risk allocation, suggesting Deep Yellow may tighten governance around EPC/EPCM and long-lead procurement on upcoming projects.

    With Australia featuring heavily across the 123 Mining stories, companies bringing in ex-Rio Tinto executives have typically pursued more rigorous capital discipline and portfolio pruning, which could affect how Deep Yellow sequences and prioritises its project pipeline in the near term.

    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.
