Greentech Metals Ltd (ASX:GRE), a key player in the critical minerals sector, has confirmed the presence of continuous copper mineralisation at its Whundo copper-zinc project in Western Australia. Recent drilling results suggest significant potential for resource expansion, with the company focusing on two key mineralised zones, Austin and Ayshia. These findings underscore the broader capacity for growth at the Whundo site.
The company's reverse circulation (RC) drilling program spans 1,710 meters, aiming to further explore and define the extent of mineralisation within these zones. Notably, the program has yielded copper grades as high as 4.6%, further enhancing the project's profile in the critical minerals landscape.
Key Drilling Results
At the Austin zone, a standout intercept returned 16 meters at 1.2% copper (Cu), 0.12% zinc (Zn), and 0.035 grams per tonne (g/t) gold (Au) from a depth of 230 meters. Within this, a higher-grade section included 8 meters at 1.5% Cu, 0.21% Zn, and 0.039g/t Au, demonstrating a concentration of valuable minerals. These results highlight the continuity and strength of mineralisation in this part of the Whundo project.
Meanwhile, at the Ayshia zone, results were similarly encouraging. Drilling at a depth of 260 meters revealed an intercept of 10 meters at 1.2% Cu, 1.2% Zn, and 0.09g/t Au, including a 3-meter section grading 3.1% Cu, 2.6% Zn, and 0.23g/t Au. This high-grade intersection further underscores the exploration potential of the site and reinforces Whundo’s position as a promising copper-zinc project.
Geophysical Surveys and Future Exploration
Greentech Metals has also carried out Down-Hole Electromagnetic (DHEM) surveys, which have provided a clearer understanding of the geological formations at Whundo. The surveys indicate that the copper-zinc shoots at both Austin and Ayshia extend beyond the 230-meter depth level. This finding suggests that the mineralisation is open at depth, offering additional opportunities for future exploration and resource growth.
The company remains focused on leveraging these insights to further expand the mineral resource at Whundo. With 6.2 million tonnes of copper-zinc resources already delineated, Greentech Metals is poised to enhance this figure through continued exploration of down-dip extensions and other mineralised zones.
Strategic Positioning and Processing Options
Whundo is situated on a granted mining lease, offering the project a strategic advantage in terms of near-term development potential. Greentech Metals is also exploring multiple processing options to advance the project. The company’s alliance with ANAX Metals (ASX
) and potential access to Artemis Resources’ (ASX
) Radio Hill processing plant offer valuable infrastructure that could expedite the processing and production phases of the project.
The proximity to established processing facilities provides flexibility for the development of Whundo, ensuring that Greentech Metals is well-positioned to capitalise on the project’s exploration success. This infrastructure advantage reduces the need for significant capital expenditure on standalone processing plants, thereby enhancing the project’s economic viability.
Path Forward for Whundo
Greentech Metals is now preparing for the next stage of exploration, aiming to extend drilling into high-grade zones and further define the resource potential of the Whundo copper project. The company has signalled its intent to accelerate the resource-building process, with future drilling programs expected to focus on the down-dip extensions of the known mineralisation at both Austin and Ayshia.
The exploration success to date reinforces the importance of the Whundo project within the broader critical minerals landscape. As global demand for copper continues to rise, driven by the energy transition and increasing electrification, projects like Whundo are well-positioned to meet the growing needs of the market.
Conclusion
Greentech Metals Ltd (ASX:GRE) is making significant strides in advancing the Whundo copper-zinc project, with drilling results highlighting the continuity and strength of copper mineralisation across key zones. With the company’s focus on expanding its resource base and leveraging strategic processing alliances, Whundo has the potential to emerge as a key contributor to the critical minerals supply chain.
As exploration efforts continue, the potential for further resource growth at Whundo remains strong. The project’s strategic location, combined with encouraging drilling results and established infrastructure options, positions Greentech Metals for future success in the copper-zinc sector.
