South32 and AusQuest have agreed to further drilling at the Hamilton copper project, about 120km south of the world-class Cannington silver-lead mine.
AusQuest announced today it had completed assessment of assay results from a recent drilling program at Hamilton, which is subject to a Strategic
Alliance Agreement (SAA) with South32.
It said key parameters (potassic and sericite alteration) for the location of iron-oxide copper-gold (IOCG) mineralisation similar to the Ernest Henry deposit had been identified.
Magnetic targets closest to the strongest alteration were identified for further drilling.
AusQuest said it expected to have Native Title clearances for additional drill sites at Hamilton before the end of the year.
Drilling would then re-commence in 2021, immediately following the wet season.
AusQuest managing director Graeme Drew said the company was encouraged by the outcomes of the detailed review of the Stage 2 drilling results at Hamilton.
“The fact that the world-class deposit at Ernest Henry is associated with only one of many magnetic targets in that area suggests you need to test the right target before you have a chance of success,” he said.
“This is difficult terrain to explore and we are limited in the technologies we can cost-effectively use to look beneath the conductive cover.
“The combination of multi-element geochemistry and geophysics has provided us with direction for the drill-rig, which is the only truly effective way to explore in these areas.
“We are excited about the potential of this area to host major orebodies, and we will continue to use the best available science to improve the company’s chances of success.”
