Osisko Development’s Barkerville Gold Mines has signed a definitive project and construction management services agreement with JDS Energy & Mining to build the Cariboo underground gold project in British Columbia. A feasibility study completed in April 2025 outlines a “robust and scalable” underground mine, with JDS to coordinate detailed engineering, procurement and construction management across the processing plant, underground infrastructure and surface facilities. The deal signals progression from study to execution, with geotechnical design, underground access development and shaft/decline construction planning now moving onto a defined EPCM footing.

TOMRA Mining is deploying advanced sensor-based ore sorting to convert mine waste rock and tailings into saleable aggregate for infrastructure, extending mine life and reducing primary crushing and haulage demands. By separating barren from mineralised material on conveyors using XRT and other sensors, operations can upgrade run-of-mine feed, cut energy and water use in downstream comminution, and divert clean fractions for construction uses. The approach opens a secondary revenue stream while lowering waste dump volumes and long-term rehabilitation liabilities.

Sandvik is adding the mid-range RG550Be drill bit resharpening machine to its portfolio, extending coverage across both top hammer (TH) and down-the-hole (DTH) drilling with a tiered line-up of high-end, mid-range and handheld units. The OEM is targeting improved safety and ergonomics in bit maintenance, moving more grinding work off manual benches and into enclosed, purpose-built machines. For mine operators, the broader range allows closer matching of resharpening capacity to fleet size and bit type, with potential gains in bit life and drilling penetration rates.
