Larvotto Resources has begun underground development at its Hillgrove antimony–gold project in New South Wales, re‑opening historical workings to access high‑grade antimony and refractory gold mineralisation. The restart involves rehabilitating existing declines and levels, upgrading ground support, and re‑establishing services to support modern mechanised mining fleets. For geotechnical and mining teams, early focus will be on re‑assessing legacy excavation stability, water inflows and ventilation capacity to safely transition Hillgrove back into sustained underground production.

Liontown Resources has completed three years of open pit mining at its Kathleen Valley lithium project in Western Australia and is now transitioning fully to underground operations. The mine is shifting to long-term underground production targeting high-grade spodumene beneath the existing pits, supported by the Dragonfly accommodation village constructed to house the expanded workforce. The move concentrates activity on deeper ore zones, with implications for ground control, ventilation design and paste backfill planning in a hard-rock lithium setting.

Capricorn Metals will acquire the Yalgoo gold project in Western Australia from Tempest Minerals, expanding its footprint beyond the 2.1Moz Karlawinda operation near Newman. The Yalgoo package lies in the Murchison region, close to existing processing and haulage infrastructure used by multiple mid-tier gold producers. For geotechnical and mine planners, the deal signals further open-pit and potentially underground resource drilling in an established Archean greenstone belt, with scope for satellite ore trucking strategies similar to Karlawinda.
