Drilling undertaken by Hillgrove in 2019 and 2020 has successfully demonstrated that the Kavanagh copper lodes continue beneath the Giant Open Pit, where they were previously mined to a depth of 350 metres vertical.

Some highlights of the drilling (refer to Hillgrove’s ASX Release dated 10 October 2019) include;

  • 16m @ 3.0% copper, 0.21 g/t gold from 434.7 metres in KTDD187_W2,
  • 22m @ 2.5% copper, 0.11 g/t gold from 372.0 metres in KTDD187_W6,
  • 18m @ 2.3% copper, 0.16 g/t gold from 367.0 metres in KTDD187_W10, and
  • 4.46m @ 5.1% copper, 0.14 g/t gold from 440.63 metres in KTDD187_W2.

Following the 2019 drilling, a maiden 2012 JORC Code Compliant Indicated and Inferred Resource for the upper portions of the Central and East Kavanagh lodes beneath the Giant Open Pit between 900 and 750 mRL was announced, (refer to Hillgrove’s ASX Release dated 30 October 2019).

Competent Person's Statement

The information in this release that relates to the 2019 Mineral Resource Estimate for the Central and East Kavanagh underground area is based upon information compiled by Mr Peter Rolley, who is a Member of The Australian Institute of Geoscientists. Mr Rolley is a full-time employee of Hillgrove Resources Limited and has sufficient experience relevant to the styles of mineralisation and type of deposit under consideration to qualify as a Competent Person as defined in the 2012 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code)’. Mr Rolley has consented to the inclusion in the release of the matters based on their information in the form and context in which it appears.

Importantly the lodes all remain open in all directions and as such there is significant potential to substantially increase the resources with further drilling.

Kavanagh’s location on a granted Mine lease, proximity to the existing ore processing and tailing storage facility, and an existing haul road to the base of the open pit (which comes to within 50 metres of the underground mineralisation) positions the Kavanagh Underground project as a relatively low capital development. These permitted processing, tailings storage and pit haul road assets reduce the capital hurdle for the underground project by multiple years and ~$300M.
