Hillgrove Resources Limited (Hillgrove, the Company) (ASX:HGO) is pleased to provide the following Spitfire drilling update, located at Kanmantoo 55kms southeast of Adelaide in South Australia. In total, 12 diamond holes have been drilled in May 2022 for 1,311.2 metres of drilling

Overall, the Spitfire drilling has been a very successful drilling program that has continued to increase the mineralisation footprint around the Kavanagh Cu-Au system. Drill holes such as 22KVUG008 with 10.35m @ 2.38% Cu, 0.28 g/t Au and 22KVUG004 18.82m @ 0.95% Cu, 0.18 g/t Au demonstrate that the Spitfire zone is strongly continuing down-dip. The Spitfire Cu-Au zone targeted in these 12 holes is located approximately 55m east of the Exploration decline and is mineralisation that is in addition to the West, Central and East Kavanagh Cu-Au zones and in addition to the SouthWest Kavanagh and Nugent Cu-Au zones. Figures 1, 4 and 5 show the location of the Spitfire Cu-Au zone and the 2022 drilling relative to the Kavanagh Cu-Au systems

Commenting on the drilling results, Hillgrove CEO and Managing Director, Lachlan Wallace said:

'The drilling results extend the strike of the Spitfire lode to over 100m and demonstrate that the system is open at depth. The close spaced drilling enables detailed stope design at Spitfire, which is important as it shores up the mining inventory of one of the areas proposed to be mined early in the underground mine plan. The results once again demonstrate the excellent continuity of the mineral systems at Kanmantoo. Since 2019, we have drilled 122 holes and returned 143 intersections of economic grade and width, which gives us a high level of confidence that further drilling will result in further positive drill intersections, which have the potential to translate into additional resource growth and ultimately, a larger mine life.''

Further details of the drilling are provided in Appendices A and B.
