    Agnico-backed Cartier’s Cadillac gold plan: staged capex and mine metrics for engineers

    First reported on MINING.com

    30 Second Briefing

    Cartier Resources has reworked its Cadillac gold project in Quebec’s Cadillac Fault, cutting initial capex to about $198 million by staging processing with 3,000 t/d toll milling in year one and an on-site plant ramping to 4,300 t/d from year five. The fully underground mine is now planned to produce 100,000 oz/y over 16.2 years, recovering 1.61 million oz at 95% recovery from 23.1 million tonnes grading 2.28 g/t, with AISC of $2,137/oz. At a $3,600/oz gold price, the PEA shows a 27% after-tax IRR, $1 billion NPV and C$2.77 billion free cash flow, backed by Agnico Eagle’s 27% equity stake.

    Technical Brief

    • 2023 Chimo PEA relied on sensor-based ore sorting to upgrade mill feed to 4.6 g/t.
    • New Cadillac plan mines 23.1 Mt at 2.28 g/t versus 15.8 Mt at 2.7 g/t previously.
    • Growth capital now totals about C$277 million, with sustaining capital rising to roughly C$1.1 billion.
    • Total life-of-mine capital, including closure, is estimated at about C$1.65 billion.
    • Sensitivity analysis: at US$3,000/oz gold, after-tax NPV is C$497 million and IRR 16%.
    • Spot-price scenario at US$4,300/oz gold lifts NPV to C$1.57 billion and IRR to 37%.
    • December resource underpins the PEA: 10 Mt M&I at 2.4 g/t (767,800 oz) plus 35.2 Mt inferred at 2.14 g/t (2.42 Moz).
    • Around 35,000 m of drilling from 2025–2026, plus Contact and Hope sector discoveries, sit outside the current economic model.

    Our Take

    Agnico Eagle’s 27% stake in Cartier Resources fits a clear pattern in our database of Agnico seeding multiple juniors in the Quebec and Abitibi gold belt (e.g. Wallbridge Mining and Radisson Mining Resources), which likely gives it a long pipeline of optionality around the Cadillac Fault without committing full balance-sheet capital at this stage.

    The updated Cadillac/Chimo plan’s move to 23.1 Mt at 2.28 g/t, versus the higher-grade but smaller-tonnage 2023 PEA, signals a strategic tilt towards bulk underground mining along the Cadillac Fault, which may better leverage regional mill and shaft infrastructure common in the Val-d’Or camp.

    With an after-tax NPV that can reach into the billion-dollar range at higher gold prices and a market capitalisation of only C$154 million, Cartier sits in the group of Quebec gold developers in our coverage where project NPVs are several times current equity value, a setup that often precedes either strategic consolidation or staged farm-in by larger operators such as Agnico Eagle.

    Canada refining more metals: value-chain design notes for mine planners

    Canada could add up to C$98 billion a year to GDP by 2035 if it shifts from exporting raw critical minerals to more complex products, Export Development Canada says, citing rare earths, graphite, lithium, copper and uranium as priority value chains. The report points to moving beyond ore into nuclear fuel and reactor components for uranium, and into specialty conductors, transformer components and AI‑grade power grid equipment for copper, building on assets such as Glencore’s Horne copper smelter. Key constraints are long-term risk capital, skilled labour, commercialisation capacity and trade infrastructure still geared to bulk exports.

    West Africa key to gold growth: project risk and power supply notes for engineers

    West Africa’s collective gold output now exceeds China’s, and Fortuna Mining CEO Jorge Ganoza says the region’s mineral endowment and rapid permitting and development timelines make it central to any growth strategy in precious metals despite higher geopolitical risk. Fortuna, which runs two mines in West Africa and two in Latin America, is tactically shifting capital between jurisdictions and has already started ordering critical power generators and other equipment for its newly acquired Bambadji project before securing an exploitation permit. Ganoza notes that competition from global data centres is constraining generator supply, limiting miners’ ability to secure units even with higher bids.

    Newcore’s Enchi gold hits in Ghana: mine plan and grade uplift notes for engineers

    Newcore Gold has reported one of its widest, highest-grade intercepts at the Boin deposit on the Enchi project in Ghana, with reverse-circulation hole KBRC411 cutting 69 m at 2.59 g/t Au from 58 m depth, including 24 m at 6.41 g/t from 59 m, and KBRC414 returning 32 m at 0.83 g/t from 70 m, including 6 m at 3.37 g/t. The seven new RC holes, totalling 960 m over 1.9 km of strike and drilled to a maximum vertical depth of 125 m, all intersected mineralisation and target conversion of Boin’s 15.9 Mt probable reserve at 0.84 g/t and 23.5 Mt indicated at 0.73 g/t. These results, largely outside the June PFS resource that underpins a planned 5.5 Mt/y open-pit and mill producing 953,000 oz over 9.3 years, point to scope for higher-grade feed and mine plan optimisation as Newcore advances an 80,000 m programme and prepares a mining lease application.
