GreenTech Metals Ltd (ASX: GRE) has intersected a mineralised zone up to 100m wide and confirmed to plunge for at least 150m in recently completed maiden reverse circulation (RC) drilling program at the Yannery prospect, part of the company’s Whundo Copper Project in Western Australia’s Pilbara region.
These results from Yannery have not only identified significant copper mineralisation but also confirmed the presence of high- grade copper lodes, some of which were targeted by the historic underground mining undertaken some 50 to 100 years ago,” Executive Director, Thomas Reddicliffe, said.
“This is an exciting prospect for the company which based on the initial findings has the potential to add significant tonnes to our Whundo resources. Going forward we will be focussed on defining the extent of the deposit as it has not yet been systematically tested. We have also been encouraged by the DHEM survey results which shows a conductor extending down dip beyond the extent of the drilling.
“This deposit has been largely overlooked in the past, but it is now proving to be an attractive prospect due to it being at surface, with copper-dominant mineralisation and carrying gold and silver credits.”
Drill Programme
During February 2023 the company completed a 729m drilling programme comprising 15 RC holes. Many of the holes were terminated prematurely at shallow depths due to intersecting underground workings of which the locations were not accurately known. This program was exploratory in nature and aimed to expand upon previous drilling results reported by Fox Resources in 2006 and Artemis Resources in 2018.
The drilling also aimed to investigate the extent and tenor of the copper lodes that were historically selectively mined. DHEM (down hole electromagnetic) surveys were conducted on three of the drill holes after completion of the drill programme.
Forward Plans
The historic and the current drilling specifically has focussed on the shallower near surface portion of Yannery however the FLEM anomaly indicates that the body is larger and extends deeper. Going forward the company will explore the untested portions of the anomaly both laterally and down dip.
