Greentech Metals (ASX:GRE) Whundo Copper Results Indicate Significant Growth

18 September 2024

Price Sensitive Announcement $

Overview:

GreenTech Metals Ltd (ASX: GRE) has reported final assay and DHEM survey results from its 1,710m RC drill program at the Whundo Cu-Zn project, completed in early July 2024. The program, comprising five drill holes, successfully intersected thick intervals of Cu-Zn mineralisation.

Two holes drilled at Austin and Ayshia as part of the drill program both intersected their respective targets and reported thick Cu-Zn intersections of 16m and 19m respectively. Collectively, these results point to the continuation of Cu-Zn mineralisation at depth within the respective moving loop electro-magnetic (MLEM) conductor footprints and highlights the significant potential to expand the resources at Whundo by drilling.

On 13 August 2024, GreenTech announced the DHEM (Down Hole Electromagnetic) survey results for hole 24GTRC005, which targeted potential extensions to Shelby mineralisation. While hole 24GTRC005 deviated and was terminated short of target due to hole deviation, this drill hole proved ideal for using DHEM to search the deeper reaches of the Shelby FLEM anomaly with a large >400m x ~50-100m conductor plate modelled from the DHEM survey (Figure 1)

Highlights:

• 1,710m RC program results at Whundo Copper Project indicate potential for
  significant resource expansion below the six known mineralised shoots

  Austin & Ayshia

• Results for Austin and Ayshia Cu-Zn mineralised shoots confirm continuity of
  copper mineralisation down dip, including:
• Austin: 16m @ 1.2% Cu, 0.12% Zn, 0.035g/t Au from 230m, including
  8m @ 1.5% Cu, 0.21% Zn, 0.039g/t Au from 230m (hole
  24GTRC001)
  Previous high-grade drill results included:
  6m @ 2% Cu from 226m, including
  1m @ 5.4% Cu from 226m (23GTRC001)
• Ayshia: 10m @ 1.2% Cu, 1.2% Zn, 0.09g/t Au from 260m, including
  3m @ 3.1% Cu, 2.6% Zn, 0.23g/t Au from 261m (hole 24GTRC004)
  Previous high-grade drill results included:
  23.7m @ 3.2% Cu, 0.4% Zn from 209m (hole 12AYDD103)
  13.97m @ 3.4% Cu from 243.63m (hole 12AYDD109)
• DHEM (Down-hole EM) surveys confirm continuation of the Cu-Zn shoots
  down-dip at Austin and Ayshia beyond 230m depth

  Shelby

• Large conductor plate (>400m x 50-100m) modelled from DHEM survey on drill
  hole 24GTRC005 has a conductive response over 15,000 siemens, greater than
  previous responses of known mineralisation associated with Shelby1

  Copper Resource Expansion

• Whundo copper resource expansion the focus of current activities
• Whundo is situated on a granted mining lease with processing options
  potentially being available through our Alliance with ANAX or Artemis
  Resources’ Radio Hill processing plant
• Planning underway for next stage drill program to expand copper resource

Company Notes:

GreenTech’s Executive Director, Tom Reddicliffe, commented: “We’re thrilled with the stage one drill results, which show real potential to significantly grow Whundo’s current 6.2Mt copper-zinc resource by targeting down-dip extensions to our known shoots. Based on our exploration results to date we firmly believe that we can continue to expand the Whundo copper resource to potentially underpin a copper project. Furthermore, with Whundo situated on a granted mining lease and with processing options potentially being available
