    Eldorado lifts Amex stake to 27%: project economics and toll-milling lens

    First reported on MINING.com

    30 Second Briefing

    Eldorado Gold has lifted its stake in Amex Exploration to 27.3% on a non-diluted basis by acquiring 14.87 million shares at C$4 each in a C$59.5 million private transaction that appears to replace Eric Sprott’s position. Amex’s Perron project in Quebec now hosts 8.2 million tonnes of measured and indicated resources at 6.1 g/t gold (1.6 Moz), plus 5 million inferred tonnes at 4.31 g/t (698,000 oz), including the high-grade Champagne zone at 16.2 g/t. Bulk sampling at Perron is in permitting, with toll-milling discussions under way and Eldorado’s Lamaque/Sigma mill an obvious processing candidate.

    Technical Brief

    • Eldorado used the NI 62-104 “private agreement exemption”, capping consideration at 115% of market price.
    • The matched block trade comprised exactly 14,868,200 shares at C$4, mirroring Sprott’s divestment volume and price.
    • Post-transaction, Eldorado holds 38,626,330 Amex shares plus 207,000 warrants, without triggering takeover intentions.
    • The transaction typifies producers favouring strategic equity positions in juniors rather than expanding reserves solely via in-house exploration.

    Our Take

    Eldorado Gold’s move to 27.3% in Amex Exploration lines up with its capital and technology being increasingly concentrated in Québec, where our coverage already shows it committing to battery-electric fleets at the Lamaque Complex in Val-d’Or.

    At Perron’s reported grades and contained gold, the project looks technically compatible with toll-treatment or future blending options through Eldorado’s existing Sigma mill infrastructure in Abitibi, which could shorten time to cash flow versus a standalone build.

    In our database of 407 mining stories, relatively few M&A items combine high-grade gold in Québec with an acquirer already operating nearby, suggesting this deal could tighten competition for remaining independent explorers in the Abitibi belt.

    Master Drilling–Boliden Somincor raiseboring: design and planning notes for mine engineers

    Master Drilling has secured its first Portuguese contract from copper-zinc producer Boliden Somincor to construct two raisebored shafts, each 630 m deep and 4.5 m in diameter. The twin vertical excavations will be critical for long-term hoisting, ventilation or service access, demanding precise control of deviation over the full 630 m and careful management of rock stability around the 4.5 m diameter openings. For geotechnical and mine planning teams, the project signals growing availability of large-diameter raiseboring capacity in European base metal operations.

    Metso digital solutions launch: production and safety insights for mine engineers

    Metso has expanded its Metso Digital portfolio with three new platforms – Digital Production Management, Data-driven Performance Analytics and Safety Performance Platform – aimed at turning plant and fleet data into actionable production and safety decisions. Digital Production Management targets end-to-end throughput optimisation across crushing, grinding and downstream circuits, while Data-driven Performance Analytics applies advanced analytics to equipment condition and process KPIs. The Safety Performance Platform centralises incident, near-miss and behavioural data to support risk control and compliance in large, multi-site mining operations.

    IWT ‘Mine of the Future’ initiative: proving-ground trials explained for engineers

    Innovative Wireless Technologies (IWT) has been selected for negotiation of a US Department of Energy award to lead the Mine of the Future: Proving Ground Initiative, a national programme to accelerate advanced mining technologies. The initiative will focus on development, testing and deployment of new systems in operating US mines, creating dedicated proving-ground sites rather than relying on ad hoc pilots. For geotechnical and operations teams, this signals forthcoming funded trials of next-generation communications, sensing and automation platforms under real production conditions.
