Komatsu Australia is undertaking a major upgrade of its construction and mining equipment fleet, retrofitting and redesigning aftertreatment systems to meet differing emissions and safety regulations across Australian, European and other international markets. The programme focuses on aligning engines and exhaust aftertreatment with Tier 4 Final/Stage V-style limits, while maintaining machine performance for high-duty applications such as quarry haul trucks, large excavators and road construction plant. For contractors and asset owners, the changes affect fleet selection, parts stocking and maintenance planning as machines are standardised for multi-jurisdiction deployment.

Schlam has launched a new in-house engineered installation kit programme for mining truck bodies and excavator buckets, giving sites a standardised, end-to-end package covering attachment supply and fit-out. Developed under a three-year product development effort, the kits are designed to integrate with Schlam’s load and haul attachments, reducing the need for bespoke on-site fabrication and ad hoc hardware selection. For maintenance and asset teams, this points to more predictable installation times, simplified spares management and tighter control of attachment interface geometry.

Integra Resources’ updated feasibility study for the Florida Canyon heap leach mine in Nevada lifts proven and probable reserves 74% to 1.1 million oz at 0.31 g/t, raises planned output to 82,000 oz gold per year over eight years, and boosts the 5% NPV to US$601 million using a US$4,200/oz price. All-in sustaining costs climb 43% to US$2,331/oz with recovery steady at 62%, but post-tax free cash flow is projected at US$800 million, averaging US$90 million annually. Integra is drilling 42,500 metres around the existing operation to grow resources and fund its DeLamar gold-silver project in Idaho.
