Gold slipped below $5,100/oz on Friday, touching about $5,020 and heading for a second straight weekly loss as the Middle East war drives up oil and gas prices and keeps interest rate cut expectations low. The metal has traded in a tight $5,000–$5,200/oz range since an early-month spike after the US-Israeli strike on Iran, and is now almost 9% off its late-January record near $5,600/oz, though still 17% higher year-to-date. Silver fell almost 5% to just above $80/oz, with only a 10% gain so far in 2026.

Rio Tinto is slowing construction of the Nemaska lithium hydroxide conversion plant at Bécancour, Quebec, cutting its contractual workforce by about 50% while keeping several hundred workers on site, but still targets commissioning this decade and first production in 2028. The plant is roughly 70% complete, designed for 32,000 tonnes per year of lithium hydroxide, with Rio planning US$300 million of investment alongside a C$200 million commitment from the Quebec government, which retains 46.1%. Nemaska’s integrated project is based on a 26‑year Whabouchi open‑pit/underground mine producing 200,000 tonnes of spodumene concentrate annually, though Rio is reassessing feed against its Galaxy hard rock project, with a decision due in H2 2026.

FLS is advancing its vertical media regrind mills, with Global Product Line Manager Peter Wulff emphasising attrition-based grinding that delivers finer particle sizes at lower specific energy than conventional ball mills. The latest designs integrate high-efficiency drives and advanced process control to cut CO₂ emissions per tonne milled, targeting operations dealing with lower head grades and higher hardness ores. For plant designers, this points to smaller footprint regrind circuits, reduced steel media consumption and improved liberation for downstream flotation.
