Highlights

  • New mineralised copper-gold zone identified at Kanmantoo
  • Drilling results set to support future resource updates
  • Exploration work continues across multiple targets

Hillgrove Resources (ASX:HGO) has identified a new high-grade copper-gold zone within its Kanmantoo operations in South Australia. This discovery marks another significant step in the company’s ongoing exploration strategy, highlighting the depth of mineral potential within the well-established mining district.

The recent drilling results were presented at a leading industry event, where the company emphasised how ongoing exploration supports its vision for sustainable production growth. While Hillgrove is not a part of the ASX 200 companies, the progress at Kanmantoo underscores the broader strength of the mining sector within the Australian market.

Ongoing Drilling and Exploration

The newly discovered “saddle” zone was intersected during extensional drilling at the Nugent extension. Early indications suggest the zone could provide meaningful additions to the company’s future operational plans. Hillgrove is prioritising follow-up drilling to better understand the size, shape, and continuity of this mineralised body.

These results are expected to be incorporated into the upcoming mineral resources and ore reserves update later this year, ensuring the company’s exploration success feeds directly into its long-term production planning.

Kanmantoo Development Plans

Work continues across the broader Kanmantoo system, with ongoing drilling programs designed to guide stope definition and development planning. Targets such as Emily Star, Critchley, and Paringa are also scheduled for near-term exploration, broadening the company’s understanding of the mineral system.

The new saddle zone’s location between existing mining areas enhances the opportunity for near-term integration into operations. Proximity to infrastructure provides the advantage of efficient access, supporting a streamlined approach to evaluation and potential future development.

Long-Term Outlook

After many years of activity at Kanmantoo, Hillgrove continues to uncover new deposits within familiar ground. The recent discovery demonstrates the lasting exploration upside of the district and reaffirms the company’s commitment to expanding its resource base.

With ongoing drilling programs and multiple exploration targets underway, Hillgrove remains focused on building long-term value from its established operations while continuing to advance opportunities for future production growth.
