Greenewood Drilling Yields 4m at 43 g/t Gold in Maiden Program
Marmota Limited reports exceptional high-grade gold intersections from its maiden drilling program at the Greenewood discovery in South Australia, with detailed 1-metre assays underway to refine the promising results.
- Maiden drilling reveals bonanza-grade gold intersections up to 43 g/t
- Mineralised zone extends nearly 900 metres along strike
- 146 RC holes drilled totaling over 15,000 metres
- Detailed 1-metre split assays collected and sent for analysis
- Greenewood located near Marmota’s flagship Aurora Tank deposit
A New Chapter for Greenewood
Marmota Limited (ASX – MEU) has delivered a compelling update on its maiden drilling program at the Greenewood gold discovery in South Australia’s Gawler Craton. The initial results, announced earlier this month, showcased bonanza-grade gold intersections, including a standout 4-metre interval grading 43 grams per tonne (g/t) of gold. These findings mark the highest-grade intercept recorded at Greenewood to date and signal a significant step forward for the project.
The Greenewood deposit, part of the Golden Moon Joint Venture where Marmota holds a 90% stake, has now been delineated over an impressive 900-metre strike length. This near-continuous mineralisation zone was confirmed through a comprehensive reverse circulation (RC) drilling campaign comprising 146 holes and totaling more than 15,000 metres. The drilling, completed in August 2025, represents the first substantial exploration activity at Greenewood since 2018.
From Composite to Detailed Assays
While the initial assay results were reported as 4-metre composites, Marmota has swiftly moved to collect detailed 1-metre split samples from the identified mineralised intervals. These samples have been dispatched to the laboratory, with results expected within the next month. This granular data will provide a clearer picture of the grade distribution and continuity of the gold mineralisation, crucial for refining resource estimates and guiding future development plans.
The high-grade intersections are complemented by thick mineralised zones, with some intervals extending up to 28 metres at grades exceeding 6 g/t. Such thickness and grade near surface enhance the potential for economically viable mining operations, particularly given Greenewood’s proximity to Marmota’s flagship Aurora Tank deposit. The latter has demonstrated excellent metallurgical recoveries and low-cost production potential, suggesting possible synergies and economies of scale across the region.
Strategic Location and Growth Potential
Greenewood sits within the so-called “Arc of Six” gold deposits in the northwest Gawler Craton, a region known for significant gold endowment including the nearby Challenger Mine, which has produced over a million ounces. Marmota’s ownership of five of these deposits, including Greenewood and Aurora Tank, positions the company strategically to leverage infrastructure and exploration knowledge across the belt.
Dr Colin Rose, Marmota’s Chairman, highlighted the significance of the results, noting that Greenewood is delivering some of the best gold grades seen in the region since the Challenger discovery in 1995. The continuity of high-grade mineralisation along strike and close to surface opens new avenues for resource expansion and development.
Looking ahead, the detailed 1-metre assay results will be pivotal in confirming the new geological model and guiding the next phase of exploration and resource definition. Marmota’s methodical approach and rapid assay turnaround underscore its commitment to unlocking the full potential of Greenewood.
Bottom Line?
As detailed assays approach, Greenewood’s bonanza grades could reshape Marmota’s growth trajectory in the Gawler Craton.
Questions in the middle?
- Will the 1-metre split assays confirm the continuity of bonanza-grade gold?
- How will these results impact Marmota’s resource estimates and development timeline?
- What synergies can be realised between Greenewood and the nearby Aurora Tank deposit?
