    Core Lithium’s Finniss restart: ramp-up, cash and plant notes for mine planners

    Core Lithium’s Finniss restart: ramp-up, cash and plant notes for mine planners

    First reported on Australian Mining

    30 Second Briefing

    Core Lithium has restarted mining and processing at its Finniss lithium operation in the Northern Territory, reporting $17.8 million in revenue for the 12 months to 30 June as it transitions out of care and maintenance. The company now targets steady-state production by 2028, backed by a materially stronger cash position after a difficult price environment for spodumene concentrate. For mine planners and process engineers, the restart signals renewed demand for contractor services, drilling, and plant optimisation as Finniss ramps back towards nameplate throughput.

    Technical Brief

    • Cash position described as “substantially stronger”, providing runway for staged ramp-up and contractor engagement.
    • Mining and processing restart follows a defined transition out of care-and-maintenance operating mode.
    • Restart timing sets up a multi‑year ramp profile towards the 2028 steady‑state production target.
    • Stronger balance sheet reduces short‑term price‑driven shutdown risk compared with the prior financial year.

    Our Take

    The 2028 steady-state target at the Finniss lithium operation lines up with recent underground development at BP33 and first concentrate production reported in September 2026, signalling Core Lithium is pacing mine development and plant ramp-up to converge on a multi-source feed strategy rather than a single-pit profile.

    With only $17.8 million in revenue over the last 12 months, Finniss remains in an early cashflow phase compared with other lithium entries in our mining database, which suggests Core Lithium will be highly sensitive to any further delays or grade variability during ramp-up in the Northern Territory.

    Board strengthening at Core Lithium, including the appointment of Tim Goyder noted in the July 2026 coverage, indicates the company is pairing the technical ramp-up at Finniss with governance and capital-markets experience typically associated with more mature Australian lithium producers.

    Gold price slides on strong dollar: planning implications for mine projects

    Gold prices slipped to a one-week low as spot gold fell 0.4% to $4,271.16/oz in New York and December futures eased 0.3% to $4,306 amid a stronger US dollar and expectations of more hawkish US Federal Reserve rate moves. The dollar hit a two-month high and US 10-year Treasury yields hovered near a 20-year peak, sharply raising the opportunity cost of holding non-yielding bullion. Oil gained about 1% on stalled US–Iran talks over the war, while spot silver dropped 1.8% to $63.29/oz, platinum 0.2% to $1,746.44, and palladium rose 0.5% to $1,266.40.

    OceanaGold Waihi expansion: design, throughput and tailings notes for engineers

    OceanaGold is weighing a 50% expansion of its Waihi plant to 1.2 Mt/y after Wharekirauponga drilling returned standout intercepts including 6.3 m at 97.2 g/t Au from 481.5 m in the East Graben vein and 8.5 m at 41.5 g/t from 399 m. The move would enable concurrent feed from Martha Underground and Wharekirauponga post‑2032, building on a 2024 plan outlining 1.6 Moz over 15 years and an initial 4.1 Mt reserve at 9.2 g/t. Underground development is advancing, with the Waihi North decline now 350 m, first vent shaft under construction, staged commissioning of a new water treatment plant, and early works on a new tailings storage facility due in Q4.

    Kinross Gold output cut and higher AISC: operational drivers and FCF lens for mine teams

    Kinross Gold has cut its 2026–27 production outlook by about 8% to 1.84–1.86 million attributable gold-equivalent oz. a year and raised 2024 AISC guidance to $1,850–$1,900/oz after winter storms, copper-rich sulphide ore and poor recoveries at La Coipa in Chile, plus weaker mining rates, grades and recoveries at Round Mountain Phase S in Nevada. The company is stockpiling high-copper material, studying a new flotation circuit for deeper sulphide mineralisation that may overlie a copper porphyry system, and using a smaller shovel at Round Mountain to cut dilution. Despite the operational hit and a Q3 output cut to about 425,000 oz., Kinross has lifted its 2026 shareholder return target to 50% of free cash flow and has already returned about $800 million this year, mainly via $655 million in buybacks.
