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

    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.

    Tapojärvi at Sotkamo Silver mine: continuity and risk notes for production engineers

    Tapojärvi has restarted as main mining contractor at Sotkamo Silver’s underground silver mine in Finland, resuming a role it previously held from 2018 to 2023 under a new agreement signed in June 2025. The contract covers full-scale production mining services, including drilling, blasting, loading and haulage in a familiar orebody and infrastructure, allowing rapid ramp-up using existing site knowledge and established operating procedures. For geotechnical and production engineers, continuity in contractor, ground control methods and equipment fleet should reduce interface risk and support stable output planning.

    STRACON’s Los Bronces tailings dam contract: lifecycle model insights for engineers

    STRACON has secured an integrated engineering, construction, financing and long-term operations and maintenance contract for the Pérez Caldera Tailings Dam at Anglo American Sur’s Los Bronces copper operation in Chile’s Lo Barnechea district. The scope combines dam design and build with funding and multi-year O&M, signalling a bundled delivery model for critical tailings infrastructure rather than separate EPC and operator contracts. For geotechnical and tailings engineers, this points to growing demand for contractors capable of lifecycle stewardship under Chile’s stringent post-Brumadinho regulatory environment.

    Metso’s third orders for Almalyk copper smelter: design and ramp-up notes for engineers

    Metso has booked the third tranche of orders for JSC Almalyk Mining and Metallurgical Complex’s copper smelter project in Uzbekistan, following equipment and project services contracts announced on 9 August 2024. The first two tranches, totalling €146 million, were booked in Q4 2024, with the latest booking covering additional core process equipment and associated services for the greenfield smelter complex. The staged order intake signals a multi-phase build-out where process design, commissioning support and long-lead items will be critical for throughput, energy performance and sulphur capture compliance.
