GreenTech Metals Limited (ASX: GRE) announced promising assay results from its drilling program at the Whundo Copper project in Western Australia’s Pilbara region. Drilling, totaling 1,187 meters, targeted two major conductors at the Shelby and Austin ore shoots, revealing significant copper mineralization. Key intercepts include 7.14m @ 1.46% Cu, 1.23% Zn, 0.08g/t Au from 277.16mm at Austin, and 9.94m @ 1.32% Cu, 0.18g/t Au from 598.2m at Shelby.
The drilling program successfully confirmed the persistence of high-grade copper mineralization beyond known mineralized envelopes, suggesting resource expansion potential. New Electromagnetic (EM) surveys indicate highly conductive plates (15,000 – 40,000 siemens) continuing down-plunge at both Austin and Shelby, further bolstering expansion prospects. Executive Director Tom Reddicliffe expressed enthusiasm, stating the results validate the potential scale of the Whundo project, and conceptual mine studies are set to commence.
Assay results are also being assessed for critical metals, prompted by elevated Gallium reports in several drill samples. Down Hole Time-Domain EM (DHTEM) surveys completed on each drill hole reported a continuation of highly conductive plates down plunge at both Austin and Shelby, solidifying the potential for resource increase at both of these under explored mineralised shoots.
The company is planning further drill holes to expand the copper resource at the Whundo Project, in light of current high copper prices of approximately US$9,500/tonne. The drilling to date confirms that the existing Cu-Zn resources of 6.19Mt @ 1.12% Cu, 1.04% Zn can be significantly expanded with further drilling along strike and at depth.
