Larvotto Resources (ASX:LRV) has begun underground development at the Hillgrove Antimony-Gold Project in New South Wales, with privately held PYBAR Mining Services mobilised on site.
The mining services company will conduct activities at Hillgrove including decline and lateral development, rehabilitation, ground support installation, and haulage for an initial four-year development plan over a 20km area.
This campaign follows on from underground mine development, which has already developed ore that is awaiting stoping methods.

Managing Director Ron Heeks says underground development activities underway with PYBAR’s guidance is one of the “final requirements to bring the Hillgrove Project back into production”.
“We are delighted with the process and how PYBAR have integrated into the site team, with now over 70 Larvotto employees on-site and 80 third-party, as we are now firmly in execution mode,” Heeks says.
“It has been an incredibly busy 2025, having achieved many financial, technical, and project milestones and now turning our full focus on exploration and site development, to increase our resources and bring the project back into production next year.”
Larvotto Resources, which has a market capitalisation of $577.04 million, is an Australian explorer focused on developing its dual-commodity Hillgrove Project, which is set to begin production in 2026.
