    Shut Nova Scotia mine’s $86M gold: stockpile plan and closure lens for engineers

    St Barbara has secured Nova Scotia approval to reprocess about three million tonnes of 0.4 g/t stockpiled ore at the closed Touquoy gold mine, targeting 38,000 oz of gold over 10–14 months with all-in sustaining costs of $1,598/oz and capital outlay of C$11.4 million to refurbish the mill. The industrial permit prohibits new mining, confines activity to the existing footprint, and requires all tailings to be backfilled into the open pit under an C$80 million reclamation bond. The campaign, expected to support 197 jobs, also underpins St Barbara’s 15‑Mile hub concept, aiming for 100,000 oz/year from 2030–2040 across 697 sq. km and 56 exploration targets.

    Silt pollution in UK construction: practical control measures for project teams

    Construction’s role in more than one-third of UK carbon emissions is widely acknowledged, but its contribution to acute silt pollution from earthworks, dewatering and runoff from haul roads and stockpiles is still largely overlooked. Fine sediment washed from sites into watercourses can smother spawning gravels, clog culverts and foul SuDS assets, often breaching Environment Agency permits and triggering costly stop-work notices. The piece calls for more rigorous use of silt fences, settlement lagoons and lamella clarifiers, plus better phasing of bulk earthworks to keep disturbed areas and exposed cohesive soils to a minimum.

    Iranian engineers rapidly restore airstrike-hit rail bridges: methods and risks for designers

    Iranian rail engineers have reportedly restored services on the key Tehran–Tabriz and Tehran–Mashhad corridors after April 2026 US/Israeli airstrikes damaged multiple rail bridges. Local reports state that temporary repairs and rapid structural assessments have allowed traffic to resume on spans that had suffered direct blast impacts and deck damage, rather than full girder replacement. The response suggests a focus on emergency shoring, expedited load rating and staged reopening, with longer-term reconstruction of primary bridge elements likely to follow under traffic constraints.
