Buffalo Potash has secured Saskatchewan approval to complete construction and operate its Disley initial production module, a 125,000 t/y soluble-grade potash facility 50 km northwest of Regina using a patented horizontal line-drive brine circulation method through parallel horizontal wells. The C$41.5 million module will test selective underground dissolution of potassium chloride with sodium-chloride-saturated brine and supply local agriculture, drilling-fluid markets and potassium-chloride brine for regional oilfields, ahead of planned 500,000 t/y Disley East and West expansions to about 1.13 Mt/y. The permit, which runs to 30 April and excludes future modules, requires groundwater characterisation, air-quality compliance and financial assurance, while the project proceeds without a feasibility study or declared reserves, elevating technical and economic risk.

Exiro Minerals, Orion Resource Partners and Canada Growth Fund have acquired an 81.1% stake in Vale’s Thompson nickel operations in northern Manitoba, committing up to US$200 million to sustain and develop the six-decade-old complex. The new vehicle, Exiro Nickel, takes over day-to-day control of two operating underground mines, the adjacent concentrator and exploration ground along the 135 km Thompson Nickel Belt, while Vale Base Metals retains an 18.9% interest. A multi-year offtake agreement keeps Vale buying nickel concentrate from the Thompson mill, providing a defined outlet for future production.

Moeve and Emerita Resources have signed Spain’s first mining-sector agreement to deploy 100% renewable diesel (HVO) at industrial scale, designating Moeve as preferred supplier of this second-generation biofuel. The HVO, derived from waste and residue feedstocks rather than food crops, is claimed to cut lifecycle CO2 emissions by up to 90% compared with conventional diesel. For mine operators, the drop-in fuel compatibility with existing diesel engines offers a near-term route to decarbonise haul trucks and auxiliary fleets without major equipment changes.
