    Cornish Metals’ $210M South Crofty funding: capex and restart lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    Cornish Metals has secured a $210 million, six-year bond at a fixed 13.5% coupon to advance the restart of the South Crofty tin mine in Cornwall, with CEO Don Turvey saying the company expects to be fully funded ahead of a final investment decision this summer. The move follows a non-binding US EXIM Bank letter of interest for up to $225 million linked to future tin concentrate exports and comes as tin prices approach $54,000/t after gains of almost 40% in 2025 and 34% year-to-date. South Crofty hosts 2.9 Mt indicated at 1.5% Sn and 2.63 Mt inferred at 1.42% Sn, with a PEA outlining a 14-year life and average output of 4,700 t/y tin, peaking at 5,000 t in year four.

    Technical Brief

    • Six-year bonds are structured with a fixed 13.5% annual coupon, locking in high-cost debt servicing.
    • Investor demand came from Europe, North America and other international markets, diversifying funding exposure.
    • US EXIM Bank’s non-binding letter of interest is for up to $225 million of export-linked debt.
    • South Crofty previously operated for over 400 years before closure in 1998 due to low tin prices.
    • Cornish Metals acquired South Crofty in 2016 after multiple unsuccessful revival attempts by other operators.
    • Current resource includes 2.9 Mt indicated at 1.5% Sn and 2.63 Mt inferred at 1.42% Sn.
    • Near-mine exploration target is 6–13 Mt grading 0.5–1.8% Sn, offering substantial upside to mine planning.
    • Tin prices have risen ~40% in 2025 plus 34% year-to-date, approaching $54,000/t, materially improving project economics.

    Our Take

    US Export-Import Bank appears repeatedly in our recent mining coverage, backing or assessing projects from Cornish Metals’ South Crofty to McEwen Copper’s large copper-gold build in Argentina and Highland Copper’s US projects, signalling that EXIM is becoming a central financier for Western-aligned critical mineral supply chains.

    With South Crofty’s indicated tin grades around 1.5%, the project sits at the higher end of underground tin grades in our database, which should give Cornish Metals more resilience if tin prices retrace from the roughly 34–40% gains noted for this year and 2025.

    MAV2205 shaft–hub locking devices: bending load insights for conveyor engineers

    MAV2205 shaft–hub locking devices are being engineered specifically for mining conveyor pulleys where high belt tensions and heavily loaded drive or bend drums impose severe bending loads on the pulley shaft, not just torque. By clamping concentrically along the shaft–hub interface, the unit spreads bending stresses more evenly than traditional keyed or welded connections, reducing local stress concentrations that initiate fatigue cracks. For designers and maintenance teams, this supports longer pulley service life, fewer unplanned shutdowns and more predictable performance in high-tension conveyor duty.

    Regis wins McPhillamys court challenge: approvals reset and design notes for mine planners

    Regis Resources has won a Federal Court challenge over its McPhillamys gold project in New South Wales, with the court declaring invalid a Commonwealth heritage protection declaration that had halted development. The 14 October ruling sends the project back to federal Environment Minister Murray Watt for redetermination, reopening the approvals pathway for the planned open-pit operation near Blayney. Geotechnical and mine planning teams can now resume work on pit design, waste rock emplacement and associated infrastructure, pending any new heritage conditions.

    Alkane’s deeper gold at Peak Hill: geotechnical and mine planning takeaways

    Alkane Resources has intersected gold–copper mineralisation about 1km below the former Proprietary open pit at Peak Hill, NSW, in 1651m diamond hole PHD084, which cut altered zones with low-grade mineralisation interpreted as a continuation of the Peak Hill epithermal system. The company is weighing a follow-up deep drilling campaign targeting this down-plunge potential beneath the historic open pit. For geotechnical and mine planners, any future underground concept will hinge on rock mass conditions at >1km depth and interaction with the existing pit wall and backfill.
