Drilling Update at Kanmantoo Mine Lease
Hillgrove Resources has shared an update on its underground diamond drilling activities at the Kanmantoo Mine Lease, located near Adelaide, South Australia. Drilling began in May 2022 from the Exploration Decline and resumed alongside production activities in July 2023. To date, a total of 96 underground (UG) drill holes have been completed, covering 10,511.31 metres.
Significant Copper Vein Discovery
A notable intersection was observed in the drilling process, distinct from the nearest exploration drill hole, KTDD202, which previously intersected 12m at 1.73% copper. The recent drilling revealed a significant run of 36.6m at 3.35% copper, showcasing the local variability and intensity of the copper veining in the mineralized zones.
Ongoing Drilling and Stope Design
While the underground drilling has not yet covered all proposed stope areas, particularly the West Kavanagh stope areas due to current decline access, it is contributing to the geological data density. This data is instrumental in finalizing individual stope designs in preparation for the anticipated commencement of copper production next year.
CEO’s Insights on Drilling Progress
Lachlan Wallace, CEO and Managing Director of Hillgrove, expressed satisfaction with the high-grade core findings, emphasizing their significance in infill drilling and stope design. He noted the priority is on the geological reconciliation of early stopes crucial for initial revenues. The advancement of the decline and establishment of additional underground drill platforms will facilitate further drilling in these areas. Additionally, the company has mobilized extra drilling capacity to expedite the gathering of drilling information from early stopes and to follow up on recent discoveries, like the step-out hole at Spitfire, which indicated promising copper and gold intersections.
