Iltani Resources’ Orient project in North Queensland, billed as one of Australia’s largest silver–indium developments, has reported standout 2025 drilling results that support a potential resource expansion. The polymetallic system targets silver, indium, zinc and lead, with recent intercepts extending known mineralisation along strike and at depth beyond the current drilling grid. Iltani is now planning follow-up step-out drilling and updated resource modelling, which could materially influence mine design, metallurgical testwork priorities and long-term development options for the Orient tenements.

Australian explorers are advancing silica sand, gold and rare earths projects, with silica gaining attention as a feedstock for solar glass and high‑purity industrial applications. Activity is concentrating in Western Australia and Queensland, where juniors are drilling shallow, laterally extensive sand deposits and following up high‑grade gold intercepts near existing processing hubs. For geotechs and mine planners, the focus on near‑surface, free‑digging sand bodies and brownfield gold step‑outs points to relatively low strip ratios, simpler pit designs and faster development timelines than deeper hard‑rock projects.

Recent diamond drilling at Larvotto Resources’ Clarks Gully prospect within the Hillgrove gold–antimony project in New South Wales has returned a “standout intercept”, strengthening the case for higher-grade underground mineralisation. The work forms part of a targeted diamond programme testing extensions of known lodes beneath historical workings at Hillgrove, a past producer with multiple steeply dipping, narrow-vein structures. For geotechnical and mine planning teams, the results point to continued focus on underground access, ground support in vein-hosted systems, and potential sequencing of gold–antimony stopes.
