GreenTech has contracted a drill rig for mobilisation to site in late July 2026, with a second rig due to arrive once additional areas have heritage clearance. The board has approved an exploration program comprising 4,750m of RC and 3,560m of DD drilling, allowing for wider-diameter diamond drilling to support metallurgical composite collections at Whundo.
CEO, James Rattenbury, said the company is advancing planning for the Munni Munni drill program ahead of mobilisation.
“We have been working to incorporate targets most likely to extend copper dominant zones of the historic resource footprint. We see an opportunity to target shallow mineralisation on existing pads ahead of the heritage survey, while also prioritising extensional drilling for high grade copper and gold at Whundo.
“The commencement of the fixed-loop electromagnetic (FLEM) survey is a pivotal step in refining our drill targets at Munni Munni. The basal contact of the intrusion is largely untested and highly prospective for copper sulphide mineralisation. The FLEM method has a proven track record in this style of setting, as demonstrated at the nearby Andover complex, and we are confident it will sharpen our targeting ahead of drilling.”
Mr Rattenbury said the increasing importance of copper as a value driver for Munni Munni has prompted an expanded metallurgical testwork focus in support of our planned resource re-estimation.
“This work programme is ongoing with anticipated completion in August. Parallel discussions with potential offtakers have highlighted the importance of maximising copper value in concentrate, and we look forward to reporting further progress in due course.”
Drill locations will initially be limited to existing drill pads at Munni Munni, and will be expanded following completion of the heritage survey scheduled at Munni Munni in mid-August.
Follow-up drilling at Whundo will be focused on shallow extensions of known high-grade copper-gold mineralisation and will also support collection of a metallurgical sample to enable testwork on recovery of gold and silver ahead of completing a resource update.
