ESG pressure in underground mining is pushing operators to prove real-time performance gains directly at the development face, where ventilation, ground control and water management risks are highest. The piece points to digital instrumentation at headings – such as continuous gas monitoring, geotechnical convergence sensors and real-time dust sampling – feeding live dashboards that link face conditions to ESG metrics. For engineers, this means designing headings, support patterns and services to accommodate dense sensor networks, data cabling or wireless nodes, and rapid-response controls rather than periodic inspections.

Glencore is restarting nearly US$300 million of emissions‑reduction projects at its Horne copper smelter in Rouyn‑Noranda after Quebec’s Bill 11 extended the deadline for cutting ambient air arsenic to 15 ng/m³ until 2029‑30 and maintained that limit to at least 2033. The company warns that almost US$1 billion in wider five‑year spending on the Horne–CCR chain still depends on federal backing via Ottawa’s C$5 billion Strategic Response Fund. Horne, Canada’s only copper smelter, processes about 210,000 tonnes per year of copper and precious metals from concentrates and e‑waste.

PeaceGold Trading and UK-headquartered SigraFi have signed a long-term supply and growth-capital deal covering fully traceable artisanal gold doré from cooperative-based producers in Ituri province, eastern DRC. The partnership currently links SigraFi’s compliant sourcing, logistics and refinery-access platform to about 11 mining cooperatives representing nearly 25,000 miners and support workers, with a revolving working capital facility tied to future gold deliveries. For mine planners and ESG teams, the structure offers a template for financing mercury-reduction, legalisation and export-compliance upgrades in artisanal supply chains.
