Hertha Metals has broken ground on its $100 million Hertha Chalyx plant in Conroe, Texas, designed to produce about 10,000 tonnes per year of combined steel-grade and magnet-grade high-purity iron using domestic ore from Minnesota’s Iron Range and Texas natural gas. The facility, adjacent to the Pi100 pilot plant where 99.95% purity was achieved in August, will scale Hertha’s FLEXHERS process, which couples electric arc furnace technology with natural gas or hydrogen. First magnet-grade output is targeted for early 2028, feeding US NdFeB magnet makers that currently rely on China for an estimated 94% of high-purity iron.

PC Gold has identified a new high-grade North Link zone immediately north of the existing mineral resource estimate at its Spring Hill gold project in the Northern Territory, based on recent reverse-circulation drilling targeting mineralisation extensions. The North Link structure is interpreted to connect with known lodes within the current MRE footprint, potentially extending strike continuity and adding shallow, open-pittable ounces. For mine planners and geotechs, the result signals a need to revisit pit shell optimisation, geotechnical domains and slope design north of the present resource limits.

Larvotto Resources has reported high-grade gold–antimony–tungsten intercepts from four lodes at the Metz Mining Centre within its Hillgrove project in New South Wales, including a newly identified lode named Echidna. Key results include 20.5m at 9.4g/t gold equivalent (AuEq) from 342.5m at Blacklode, with a higher-grade core of 6.2m at 27.2g/t AuEq from the same depth. The grades and depths point to underground mining potential and support further resource definition drilling targeting multi-commodity sulphide mineralisation.
