Whundo Drilling Yields High-Grade Copper-Zinc Intercepts; Lithium JV Secured
GreenTech Metals has reported promising drilling results at its Whundo Copper-Zinc project, confirming significant down plunge mineralisation and advancing resource expansion. Meanwhile, it has formed a 50/50 lithium joint venture with Artemis Resources, creating the largest lithium exploration package in the West Pilbara.
- High-grade copper-zinc intercepts confirmed at Whundo’s Austin and Shelby prospects
- Down Hole Time-Domain EM surveys validate extensive down plunge conductor extensions
- Stage 2 drilling underway targeting resource expansion at multiple mineral shoots
- Formation of Andover Lithium JV with Artemis consolidates lithium rights over 420 km
- Company ends quarter with $1.3 million cash following successful capital raise
Whundo Copper Project Advances
GreenTech Metals Limited (ASX, GRE) has made significant progress in its West Pilbara copper-zinc exploration during the March 2025 quarter. At the 100% owned Whundo project, recent diamond core drilling totalling 1,187 metres tested two major conductors at the Austin and Shelby prospects. The results revealed high-grade mineralised zones, including intercepts such as 7.14 metres at 1.46% copper and 1.23% zinc at Austin, and 9.94 metres at 1.32% copper at Shelby. These findings reinforce the potential to expand the existing JORC resource of 6.2 million tonnes grading 1.12% copper and 1.04% zinc.
Complementing the drilling, Down Hole Time-Domain Electromagnetic (DHTEM) surveys confirmed significant down plunge extensions of these conductors, suggesting mineralisation continues well beyond previously known limits. The Shelby conductor, for example, exhibits a high conductance of over 20,000 siemens and extends more than 400 metres down plunge. This geophysical evidence supports the company’s strategy to focus its Stage 2 drilling program on down plunge and lateral extensions of mineral shoots at Austin, Shelby, Yannery, and Ayshia.
Strategic Lithium Joint Venture Formation
In parallel with its copper-zinc activities, GreenTech has entered a binding agreement with Artemis Resources (ASX, ARV) to consolidate their lithium mineral rights in the West Pilbara. The joint venture company, Andover Lithium Pty Ltd, will hold a combined tenement package exceeding 420 square kilometres, making it the largest lithium exploration landholding in the region. This package lies along the prolific Karratha-Roebourne lithium corridor, which hosts significant spodumene-bearing pegmatite outcrops and is adjacent to Azure Minerals’ Tier 1 lithium discovery.
The consolidation aims to streamline exploration efforts and attract a major funding partner to accelerate lithium exploration. Despite recent lithium price volatility, both companies remain confident in the prospectivity of their combined holdings, which include undrilled pegmatite outcrops with strong potential for new discoveries.
Financial Position and Outlook
GreenTech ended the quarter with approximately $1.3 million in cash, bolstered by a successful capital raising that delivered $1.5 million before costs in January 2025. Exploration expenditure for the quarter was $259,000, focused primarily on advancing the Whundo drilling program. The company is also evaluating near-term copper production opportunities, including potential processing through nearby facilities such as Artemis’ Radio Hill plant or the ANAX Alliance.
Executive Director Thomas Reddicliffe emphasised the company’s commitment to resource growth and strategic partnerships, highlighting that the ongoing drilling and metallurgical testing will underpin future resource upgrades and feasibility studies. The lithium joint venture is expected to enhance shareholder value by unlocking the potential of a large, contiguous lithium land package.
Bottom Line?
GreenTech’s dual focus on expanding copper resources and consolidating lithium assets positions it well for the evolving battery metals market, but upcoming drilling results and funding developments will be critical to watch.
Questions in the middle?
- How quickly can GreenTech convert its expanded copper resources into production?
- What level of funding and partner involvement will Andover Lithium attract for lithium exploration?
- How will recent lithium price fluctuations impact the economics and timing of GreenTech’s lithium projects?
