Hillgrove Resources Limited - KAVANAGH DRILLING FROM DEEPEST AVAILABLE SITE DELIVERS MINERALISATION OUTSIDE OF EXISTING RESOURCE

· Issued by Hillgrove Resources Limited

Hillgrove Resources Limited ('Hillgrove', 'the Company') (ASX:HGO) is pleased to provide the following drilling update on the drilling completed from the 750 Diamond Drill Site at its Kanmantoo Copper Mine located at Kanmantoo.

The 750 Diamond Drill Site is the deepest underground drill site and is focused on testing the Kavanagh Mineralisation System. Drilling at the 750 Diamond Drill Site commenced in April, with mobilisation of the third underground diamond drill rig.

Hole 25KVUG0597 extends the Kavanagh West mineralisation to the 590m RL. Although these are narrow intercepts, this provides confidence of the continued plunge of the Kavanagh West mineralisation and provides additional targets for drilling the southern extent of the Kavanagh system. The high grade intersection of 13m @ 2.24% Cu & 0.13g/t Au (uncut) from 109m downhole in 25KVUG0607 supports the existing mineral resource estimation however the deeper low grade mineralisation within 25KVUG0607 illustrates the geometry of the adjacent Kavanagh lodes to the north of existing drilling. Current results are consistent with the existing interpretation of the Kavanagh Mineralisation where mineralisation occurs within the structural corridor and is observed to pinch and swell based on the available pathways for mineralising fluids within the corridor. This early drilling reported in holes 25KVUG0597, 25KVUG0601, 25KVUG0603, 25KVUG0605 and 25KVUG0607 from the 750 Diamond Drill Site has continued to identify the Kavanagh lode geometry assisting to interpret the lode plunge and internal geometries. This additional information is then used in the design of future drilling from this site. Drilling is planned to continue from the 750 Diamond Drill Site for the coming months. Drilling throughout the Kanmantoo System is ongoing for both stope definition and Resource expansion drilling for the copper-gold mineralisation system with the information continuing to provide input into future planning alongside operational requirements for stope and development designs.

Commenting on the drilling results, Hillgrove CEO and Managing Director, Bob Fulker said: 'We are still in the early stages of the drilling program at the Kavanagh 750 Diamond Drill Site, but I'm encouraged by the results so far. These are the first holes drilled in this area since underground development began, and they not only reaffirm our confidence in the existing Resource but also include several intersections with grades exceeding the current average in the published Mineral Resource Estimate. One particularly positive result comes from hole 25KVUG0597, which intersected mineralisation approximately 200 metres below the current Kavanagh West stoping horizon on the 785 Level. Although the intersection is narrow, it represents the deepest mineralised hit recorded at Kavanagh West to date. This opens up a new vertical extension target with the potential to expand the Mineral Resource Estimate if this trend continues. Drilling will continue at this site over the coming months, and we see strong potential to grow our Resource base and enhance the long-term outlook at Kanmantoo. We look forward to updating the market as further results from this extensive exploration program become available.'
