Hillgrove Resources Limited unveils promising deep drilling results at its Kanmantoo Mine, identifying new copper mineralisation below current resource estimates. The findings hint at a potential resource expansion and long-term growth, drawing investor interest as drilling continues to unlock fresh high-grade targets.
Hillgrove Resources Limited has reported encouraging results from its ongoing underground drilling campaign at the Kanmantoo Copper Mine. The company’s program at the 750 Diamond Drill Site, the deepest drill location targeting the Kavanagh mineralisation system, has intercepted significant copper and gold mineralisation beyond the current resource boundaries. Notably, hole 25KVUG0597 recorded an intersection of 2.4 meters at 0.9% copper and 0.04 g/t gold approximately 238.6 meters downhole, marking the deepest mineralised hit at Kavanagh West—around 200 meters below the existing stoping horizon. Additional intervals include a high-grade result from hole 25KVUG0607 with 13 meters at 2.24% copper and 0.13 g/t gold, among other positive intercepts that enhance the understanding of the lode geometry and resource continuity across the system.
The drilling outcomes also underscore strong development advances on the mine, highlighted by the recent firing of the first South Kavanagh West stope. Alongside extensive vertical and infill drilling, these intersections support the existing resource estimate while identifying new vertical extension targets with the potential to significantly expand the mineral resource base. Technical indicators such as copper percentages ranging from 0.23% to 2.24% and gold grades up to 0.17 g/t, combined with intercept lengths varying from 2 to 13 meters, provide an early but positive insight into the complex geometry of the Kavanagh mineralisation system. The program, which has reached nearly 6,000 meters of underground diamond drilling in a month, is expected to continue over the coming months as further assay results are integrated into future resource estimations and planning.
Market sentiment may lean bullish given the discovery of mineralisation below the current resource limits and the identification of new drilling targets that could expand future reserves. The ability to extend the profitable mining horizon presents a notable upside for long-term value creation. On the other hand, a cautious view is warranted as much of the current data comes from narrow intersections and early-stage drilling, implying that further results are needed to confirm the continuity and economic viability of these mineralised zones before significant resource expansion is fully realized.
