⚒️ HIGHLIGHTS
  • RC Drilling has commenced with two holes completed at the new South Ferro Target defined by soil sampling
  • The program is targeting extensional copper resources ahead of H1 2025 JORC Resource upgrade
  • Follow up of previously untested copper-moly soil anomalies after recent heavy rains have better exposed prospective porphyry rocks NE of Ferro with over 200m diameter with channel and rock sampling currently in progress
  • High definition geophysical surveys over the entire project to better refine deeper targets at Cerro and Southern Porphyry and potentially provide new targets, currently being assessed. Including gravity, Magneto-Telluric (MT) and reprocessing historical Induced Polarisation (IP) data

⚒️ RC Drilling Summary

Drillholes 24LHRC044 and 24LHRC045 completed at 86m and 116m respectively with 24LHRC045 extended 31m beyond planned depth as copper mineralisation noted by pXRF continued.

The drilling is following up a new area south of Ferro defined by soil sampling and follow up of mineralisation intersected in 23LHRC042 with 48m @ 0.48% CuEq% from surface.

⚒️ Llahuin Extension

Field exploration following up untested soil anomalies, after recent heavy rains have better exposed prospective porphyry rock NE of the Ferro deposit, over a large ~200m+ diameter area. Channel and rock sampling is in progress.

The area is shown in the map on Figure 3 below.

⚒️ Curiosity and Cerro Deeps Targets

Further analysis of these deep targets with a highly experienced independent consultant onsite has suggested using further geophysical surveys to improve the hole targeting for the large Curiosity and Cerro Deeps Targets.

These are under evaluation for quote tendering and timing. The survey will assist with the Cerro Deeps Target as the Cerro resource is already in the vicinity and it is likely to be connected, may improve that target as well as validate the Curiosity Target. Potential new targets may well be derived from the work, as the whole project will be included in the planned survey(s).

The Cerro Deeps Target is planned to be the first one drilled given the higher level of confidence and being a large extensional resource addition if successful. Given that this drilling will cost approx. $1m for the Curiosity Target and circa $500k for the Cerro Deeps Target the additional recommendations are well worth taking on board.

Further results will be reported in due course.
