GreenTech Metals Uncovers Significant Gold at Whundo, Eyes Near-Term Production

• Significant high-grade gold intercepts up to 64.7g/t at Whundo
• Exploration Target of 15-23 million tonnes with notable copper and zinc grades
• Independent consultancy engaged for conceptual mine study
• Anomalous gold trends identified at Ruth Well Gold Project
• Company spent $738,000 on exploration and progressing mining permit applications

Significant Gold Discovery Enhances Whundo Project

GreenTech Metals Limited (ASX, GRE) has delivered a pivotal update for the quarter ending June 2025, spotlighting a substantial gold endowment at its Whundo Copper-Gold-Zinc project in Western Australia's West Pilbara region. A comprehensive review of over 50,000 historic drill hole assays uncovered high-grade gold mineralisation closely associated with copper and zinc deposits, with standout intercepts reaching as high as 64.7 grams per tonne. This discovery materially enhances the economic potential of the Whundo project, which already hosts a JORC 2012 resource of 6.2 million tonnes at solid copper and zinc grades.

Defining a Large-Scale Exploration Target

Building on these findings, GreenTech has defined a substantial Exploration Target ranging between 15 and 23 million tonnes, with copper grades from 0.9% to 1.4% and zinc grades from 0.2% to 0.4%. This suggests a significantly larger mineral system than previously recognised, potentially containing up to 265,000 tonnes of copper and 69,000 tonnes of zinc. While this target remains conceptual and requires further drilling to convert into a formal resource, it underscores the project's scale and potential.

Advancing Towards Near-Term Production

In a strategic move to evaluate production viability, GreenTech has engaged an independent mining consultancy to conduct a conceptual mine study. This study will assess various mining and processing scenarios, including the use of existing facilities such as the Radio Hill processing plant and the Anax facility at Whim Creek. The objective is to identify a feasible pathway to near-term copper-gold-zinc production, leveraging the project's established resources and recent gold discoveries.

Ruth Well Gold Project Shows Promising Trends

Beyond Whundo, GreenTech's Ruth Well Gold Project has revealed encouraging anomalous gold, silver, and arsenic trends through systematic reviews of historic and recent soil and rock chip samples. Significant rock chip assays include gold grades exceeding 5 grams per tonne, aligning with a regional structural zone known for hosting gold deposits, including the nearby Carlow Castle gold deposit with 374,000 ounces of gold. These findings support plans for focused follow-up exploration and potential initial drilling in the coming quarters.

Financial and Operational Outlook

During the quarter, GreenTech invested $738,000 in exploration activities and paid $57,000 in director and consulting fees. The company is actively planning its Stage 2 drilling program to expand and quantify resources at Whundo and associated deposits, while also progressing mining permit applications. Despite a cash balance of $358,000 at quarter-end, the company acknowledges limited runway and is in discussions with brokers to secure additional funding. GreenTech remains confident in its portfolio's prospectivity and its ability to attract capital to advance its projects.

Bottom Line?

GreenTech’s gold discoveries and exploration targets at Whundo set the stage for a critical phase of resource expansion and feasibility studies that could unlock near-term production potential.

Questions in the middle?

• How will the upcoming Stage 2 drilling results impact the current resource estimates and project valuation?
• What are the preliminary findings and timelines expected from the conceptual mine study?
• How does GreenTech plan to secure funding given its limited cash runway and exploration ambitions?
