    Kinross greenlights three US builds: capex, output and design notes for mine planners

    First reported on MINING.com

    30 Second Briefing

    Kinross Gold has approved three US projects—Round Mountain Phase X, Bald Mountain Redbird 2 (Nevada) and the Kettle River–Curlew restart (Washington)—aimed at adding about 3 million oz between 2028 and 2038 and holding group output near 2 million oz per year. Round Mountain will shift to 3,000 t/d bulk underground mining of 11 Mt at 3.2 g/t (1.2 Moz) with initial capex of US$400 million, while Curlew will feed the 1,800 t/d Kettle River mill using dry-stack tailings and US$485 million upfront spend. Bald Mountain’s Redbird 2 pushback and five satellite pits will leverage existing leach infrastructure to deliver roughly 155,000 oz per year to 2031, with a US$490 million build and a SART plant to handle higher-copper ore.

    Technical Brief

    • Combined Round Mountain, Bald Mountain Redbird 2 and Kettle River–Curlew yield a 55% after-tax IRR at US$4,300/oz.
    • At US$3,200/oz, the three-project package still carries a ~32% IRR and ~US$2 billion NPV.
    • Around US$425 million of Kinross’s 2026 capex is allocated to these US builds within a US$1.5 billion budget.
    • Management guides to roughly US$1.5 billion “flat” annual capex for the next three years, excluding inflation effects.

    Our Take

    With Kinross targeting about 2 million oz per year of gold output and adding 3 million oz from US projects between 2028 and 2038, these builds materially rebalance its portfolio toward lower-jurisdiction-risk assets in Nevada and Washington versus Mauritania (Tasiast) and Chile (La Coipa, Lobo-Marte).

    The combined after-tax IRRs of 32–55% and sub-two-year paybacks at Round Mountain Phase X, Curlew and Bald Mountain Redbird 2 are at the upper end of project returns in our recent gold coverage, signalling that Kinross can justify sustaining a flat US$1.5 billion capex envelope while still funding organic growth.

    Restarting the Kettle River–Curlew complex in Washington, where the mill already produced 2.8 million oz before 2017, reduces execution and permitting risk compared with greenfield US gold projects we track, and should allow Kinross to bring the 5.8–6.4 g/t Curlew inventory online quickly once development is committed.

    Scope Systems cyber attack: resilience and risk lessons for mining IT teams

    A ransomware attack on Perth-based Scope Systems’ Pronto Xi ERP cloud stack disrupted dozens of mining customers, including Northern Star Resources and Evolution Mining, in what MM‑ISAC’s Rob Labbe calls the broadest single third‑party cyber event the sector has seen. Scope says client servers were restored from backups and not directly accessed, but admits internal data was exfiltrated and has not disclosed the attack vector, raising questions about visibility at hypervisor, storage and backup layers. The incident spotlights how multi‑tenant vCenter/ESXi environments, VM cloning and snapshot abuse—already used by groups like Akira—could expose integrated exploration, production and maintenance data across more than 400 Pronto Xi‑reliant mining operations.

    Newmont’s Red Chris underground expansion: block cave design and capex notes for engineers

    Newmont’s Red Chris mine in British Columbia has secured an amended Environmental Assessment Certificate and Mines Act permit, allowing a shift from open-pit to underground block caving and extending operations into the mid-2040s. The copper-gold porphyry deposit in the Golden Triangle hosts an estimated 20 million oz of gold and 13 billion lb of copper, with the block cave expected to lift Canada’s copper output by about 15%. The project entails several billion dollars in capital, around 1,800 construction jobs and roughly 1,500 operating roles at peak.

    Goldman cuts gold price forecast to US$4,900: planning notes for mine projects

    Goldman Sachs has cut its end‑2026 gold price forecast by US$500/oz to US$4,900/oz after the US Federal Reserve, under new chair Kevin Warsh, signalled a hawkish shift that has pushed market-implied December rate hike odds to 87%. Spot gold has already fallen to about US$4,100/oz, down 27% from its near‑US$5,600/oz January peak, with three consecutive monthly losses between March and May and a 4% year‑to‑date decline. Goldman warns a 2026 year‑end target as low as US$4,400/oz is possible if rates rise, partly offset by ongoing central‑bank buying of roughly 50 tonnes/month this year and 40 tonnes/month next year.
