Hebei to Launch Another Round of Environmental Crackdown from October 1

KGHM Polska Miedź has marked the start of Sierra Gorda’s US$725 million fourth grinding-line expansion in Chile. The project will add crushing, grinding, flotation and associated infrastructure, increasing annual ore-processing capacity from about 48 million tonnes to 60 million tonnes. Completion is scheduled for late 2029, with full production expected in H2 2030. On a 100% mine basis, post-expansion average payable molybdenum production is expected to reach approximately 6,000 tonnes per year. KGHM reported that Sierra Gorda produced more than 8 million lb, or about 3,629 tonnes, of molybdenum in 2025. SMM analysis: the project represents a material medium- to long-term overseas molybdenum supply increment, but it will not add near-term supply.

Codelco reported a fatal accident on October 1 in the crushing and material-handling area of its Radomiro Tomic operation. Activities in the affected area were immediately suspended and an investigation was launched. Codelco has identified Radomiro Tomic as one of its molybdenum-producing mines, with sulphide ore processed through the Chuquicamata concentrator. The company has not disclosed the duration or scope of the suspension or any impact on copper and molybdenum output. SMM analysis: a prolonged or wider suspension could disrupt the processing cadence of Mo-bearing sulphide ore, but there is currently insufficient evidence to conclude that molybdenum production has declined.

[SMM Tantalum Flash] Aterian’s interim results, released on 30 September, show £1.341 million of Tantalum and other ore-sales revenue for the six months to 30 June 2026, up from £20,000 a year earlier. Gross profit was £522,000, while the group recorded a £568,000 pre-tax loss. Its Rwanda trading business deployed about US$2.18 million in working capital through joint-venture purchases. Management valued potential sales from those purchases at US$2.78 million, but cautioned that the notional valuation is not additional recognised revenue. The implied US$602,000 gross trading profit is also a management estimate, dependent on completed sales, assays, realised prices, costs and the joint venture’s profit allocation. Aterian said traceability inspections limited suppliers and volumes. It held £131,000 in cash at 30 June; its expectation of expanding trading volumes from the fourth quarter still depends on execution and funding.
