Boliden is in talks to buy Votorantim’s 64.7% controlling stake in zinc producer Nexa Resources, a deal flagged at about 7 billion reais ($1.4 billion) that would expand Boliden’s base metals portfolio into Brazil and Peru. Nexa operates five polymetallic mines, including Cerro Lindo in Peru, and three smelters, giving Boliden potential access to integrated zinc, lead and by-product capacity across two key Latin American jurisdictions. Nexa’s shares rose 2.8% in after-hours trading, valuing the company at roughly $1.8 billion, but both parties warn there is no certainty of completion.

Volvo Autonomous Solutions has signed a Letter of Intent with Jokkmokk Iron Mines AB to develop an autonomous haulage fleet for the planned Kallak/Gállok iron ore project north of the Arctic Circle, targeting operation in sub-zero, snow and ice conditions. The partners will test downsized, purpose-built autonomous vehicles rather than conventional 220–300 t trucks, aiming to optimise haul profiles, ramp geometry and energy use for a relatively compact open pit. For engineers, the project offers an early Arctic testbed for integrating autonomy with mine design, traffic management and winter road maintenance strategies.

Newcore Gold’s 80,000-metre diamond drill programme at the Nyam deposit, part of the Enchi project in Ghana, has returned above-reserve grades below existing pit shells, including 3.51 g/t gold over 21 metres from 245 metres (with 5.91 g/t over 9 metres) and 1.40 g/t over 21 metres from 317 metres. The project currently carries probable reserves of 51.3 million tonnes at 0.64 g/t (1.05 million oz.) within an indicated resource of 83.6 million tonnes at 0.56 g/t (1.5 million oz.). A new PFS, based on open-pit milling and CIL, outlines nine years at 104,000 oz./year (NPV US$496 million, IRR 37%), with analysts SCP and Haywood seeing scope for 130,000–140,000 oz./year if deeper high-grade ounces are drilled into the mine plan.
