Hidden costs from traditional pivot pin maintenance on haul trucks, forestry harvesters and excavators are driving interest in Expander System’s oversized pivot pins with tapered sleeves, according to Nord-Lock Group head of sales Robin Persson. The retrofit design allows installation in worn pivot eyes without line boring or welding, using conical sleeves to create full-surface contact and reduce clearance growth. For mine maintenance teams, this can cut repeated pin replacement shutdowns and lower life-cycle costs on high-load joints such as dump body hinges, loader booms and articulation points.

Canadian Chrome Company has formed a three-person First Nations steering committee, including former Attawapiskat Chief Theresa Okimaw-Hall and former Marten Falls Chief Lawrence Baxter, to advise on its Ring of Fire chromite, nickel, copper and platinum assets in Ontario’s James Bay Lowlands. The committee will provide Indigenous perspectives to prospective buyers or partners ahead of any sale or merger involving CCC’s 90% interest in the Koper Lake project and 30% in the Big Daddy project. Both projects remain at pre‑PFS stage, with no new economic analysis disclosed.

Boron One’s updated PEA for the Piskanja underground boron project in southern Serbia lifts the after-tax IRR to 89% and NPV (10% discount) to US$558.8 million, with unchanged initial capex of US$79.9 million and a sub‑one‑year payback, but shortens mine life to 13 years and trims average annual EBITDA to US$87.7 million. The plan now targets average yearly output of 157,600 tonnes of colemanite, 83,800 tonnes of ulexite and 25,000 tonnes of boric acid, at all‑in sustaining costs of US$231.44 per tonne. The revised study incorporates new geotechnical testing, a 3D resource model by borate type and a binding offtake for at least 25,000 tonnes of boron products per year, subject to permitting and plant qualification.
