Larvotto Resources has formalised a key contract to upgrade its Hillgrove processing plant, aiming to become a major antimony producer by late 2026. Early works are progressing, with commissioning set to unlock new production capacity.
- EPCM contract signed with MIQM for Hillgrove plant upgrade
- Processing capacity to increase to approximately 0.525 Mtpa
- New ultra-fine grinding and dry tailings circuits included
- Main transformer repaired, restoring reliable grid power
- Commissioning targeted for Q3 2026, positioning Larvotto as a major antimony supplier
Contract Execution Marks Major Step Forward
Larvotto Resources Limited has taken a decisive step in advancing its Hillgrove Antimony-Gold Project in New South Wales by signing an Engineering, Procurement and Construction Management (EPCM) contract with MIQM. This agreement sets the framework for a comprehensive upgrade and refurbishment of the processing plant, aiming to boost throughput to around 525,000 tonnes per annum.
Upgraded Plant Features and Early Works
The upgrade includes the installation of an ultra-fine grinding circuit and a filtered dry tailings system, both critical to improving processing efficiency and environmental management. Early works are already underway, focusing on secondary crushing and tailings filtration areas. Notably, the repair of the main transformer has restored stable grid power to the site, eliminating reliance on costly temporary generation and enhancing operational reliability.
Strategic Positioning in Antimony Market
With commissioning scheduled for the third quarter of 2026, Larvotto is positioning Hillgrove to become a significant Western producer of antimony, expected to supply approximately 7% of the global demand. This is particularly timely as governments worldwide prioritize securing stable supply chains for critical minerals. The project’s gold by-product also benefits from currently strong price environments, adding a valuable revenue stream.
Community and Workforce Development
Larvotto has successfully relocated its workforce to Armidale, fostering closer ties with the local community and supporting regional employment. The company’s focus on building a skilled operational team on-site underscores its commitment to sustainable development and long-term project success.
Looking Ahead
Beyond the plant upgrade, ongoing exploration efforts aim to expand Hillgrove’s resource base and extend mine life, ensuring the project’s role as a reliable supplier of critical minerals well into the future. The execution of this EPCM contract thus represents both a milestone and a foundation for Larvotto’s growth ambitions.
Bottom Line?
As Larvotto advances toward commissioning, the market will watch closely to see if Hillgrove can deliver on its promise as a strategic antimony supplier.
Questions in the middle?
- What are the detailed capital expenditure and budget parameters for the plant upgrade?
- How will Larvotto manage potential operational risks during the commissioning phase?
- What exploration results might extend Hillgrove’s resource and production timeline?
