At the 2026 Prospectors & Developers Association of Canada event, pH7 introduced an advanced heap leaching technique specifically designed for sulfide ores. The pilot-scale demonstration highlighted faster leach kinetics and higher recovery yields alongside reduced reagent consumption compared with conventional methods.

Major producers such as BHP are assessing the technology’s potential to lower capital and operational expenditures on low-grade sulfide deposits. Adoption could extend mine life, improve cash flow by accelerating metal recovery and support environmental targets through reduced chemical use.
