Arizona Eagle Mining has acquired 62 acres hosting the historic Arizona National, Lookout and Silver Belt silver mines in Yavapai County, Arizona, including an operating water well with extraction rights, extending its patented land to 410 acres. The ground lies on strike and about 1 km northeast of the McCabe gold-silver deposit, lengthening the mineralised structural corridor by 50% from 3 km to 4.5 km, where historic work defined 878,000 oz gold at 11.7 g/t and 5.12 Moz silver at 69 g/t. Surface and waste-pile sampling has returned up to 861 g/t silver and 15.6 g/t gold, pointing to high-grade underground exploration potential below historic workings limited to ~150 m depth.

Mining’s smallest bottlenecks – such as faster‑than‑predicted conveyor belt wear, poorly performing transfer points and uncontrolled dust escape – are identified as major drivers of unplanned downtime and reduced throughput in bulk materials handling. The Bulk Handling Technical Conference and Expo in Melbourne this September will focus on these everyday engineering issues, bringing together conveyor specialists, transfer chute designers and dust control vendors. For site engineers, the message is to prioritise condition monitoring and incremental design tweaks on belts, chutes and enclosures before pursuing large capital upgrades.

HVME 2027 in the Hunter Valley is being positioned as a forum for miners, OEMs and tech suppliers to confront the region’s shift from coal-dominated operations towards artificial intelligence, automation and more diversified resource projects. Organisers aim to bring together coal producers, heavy industry and emerging technology vendors to discuss practical deployment of autonomous haulage, digital fleet management and AI-driven planning across existing Hunter sites. For engineers, the event signals growing pressure to retrofit legacy coal infrastructure with advanced control systems while planning for a more mixed commodity and industrial base.
