    Sirios–OVI Mining C$23M Quebec deal: project scale and upside for mine planners

    First reported on MINING.com

    30 Second Briefing

    Sirios Resources will acquire private explorer OVI Mining in a C$23 million all-share deal, consolidating the Cheechoo, Corvet Est and Plex gold assets in Quebec’s Eeyou Istchee James Bay district about 725 km north of Montreal. Cheechoo currently hosts 34.9 million indicated tonnes at 1.12 g/t Au (1.3 Moz) and 42.7 million inferred tonnes at 1.23 g/t Au (1.68 Moz), while historic drilling totals 21,000 m at Corvet Est and 38,000 m at Plex. The merged company, expected to close in Q1 2026 under a new name, will be led by OVI CEO Jean-Félix Lepage with Osisko’s Sean Roosen joining the board, signalling a more aggressive development push around Dhilmar’s nearby Éléonore mine.

    Technical Brief

    • Sirios will issue 131,905,657 new shares to OVI holders, pricing OVI at ~C$0.17/share.
    • Combined equity value post-announcement reached ~C$63 million, with Sirios’ share price peaking at C$0.40.
    • Transaction consideration totals about C$23 million (≈US$17 million), structured entirely as an all-share deal.

    Our Take

    Cheechoo’s 1.3 Moz indicated and 1.68 Moz inferred gold inventory at grades around 1.1–1.2 g/t positions Sirios among the larger early-stage gold stories in Quebec in our database, which is dominated by smaller sub-million-ounce James Bay prospects.

    With Sirios valued at about C$63 million on its historic C$0.40/share peak, the implied market capitalisation per ounce of Cheechoo gold is low compared with several other Quebec gold developers in our coverage, suggesting room for re-rating if the OVI acquisition de-risks the project path to 2026.

    The concentration of assets in Eeyou Istchee James Bay and proximity to Canadian Malartic and Éléonore means Sirios is moving into a corridor where existing infrastructure and established operators like Agnico Eagle Mines and Osisko Mining can materially influence future JV, toll-milling, or consolidation options.

    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.
