Highlights

  • GRE shares surged over 42% to 6 cents on 5 June after new gold-copper assay results.

  • Drilling data confirms significant gold presence across all Whundo mineralised shoots.

  • Company explores near-term production potential amid favourable copper and gold prices.

GreenTech Metals Ltd (ASX:GRE) saw its share price soar more than 42% to 6 cents on the morning of 5 June following a pivotal update on its Whundo copper project in Western Australia. The market responded positively to the company's announcement that extensive drilling data had confirmed a consistent and significant association of gold with copper across all mineralised zones at the project.

The company revealed that a comprehensive analysis of over 50,000 sample assays from 1,195 drill holes demonstrated a spatially widespread gold presence, using a 0.2 g/t Au cut-off for defining mineralisation envelopes. Notably, the review identified individual drill samples returning grades of up to 64.7 g/t gold, with composite intercepts as high as 18.4 metres averaging over 1 g/t gold.

With gold and copper prices both trading at elevated levels, GreenTech is now considering near-term production opportunities involving copper-gold-zinc output from the Whundo project. 

Forward Plans and Drilling Strategy

GreenTech’s Stage 2 drill program remains focused on resource expansion and definition. Planned targets include:

  • Testing the continuity of mineralisation between Austin and Shelby (co-funded by the EIS initiative)

  • Assessing lateral and down-plunge extensions of both the Ayshia and Austin shoots

  • Investigating shallow, high-grade oxide mineralisation at Yannery

  • Collecting core samples for metallurgical testing from Whundo and Ayshia

Conceptual Mine Planning Underway

In parallel, GreenTech is advancing a conceptual mine study. Key components of this study include:

  • Updating Mineral Resource Estimates for Whundo, Ayshia, and Yannery to include gold

  • Running Whittle optimisation analyses to evaluate economic scenarios

  • Assessing the feasibility of early production, including evaluating the Radio Hill processing site as a nearby treatment option

  • Initiating the mining permit application process
