Marmota Ltd
Maiden Greenewood Drilling Program Advances at Pace
Marmota Ltd's Greenewood discovery has announced completion of Stage 2 drilling, delivering results that significantly exceed original expectations. The campaign expanded from an initial plan of 85 holes and 8,500m to a comprehensive program of 129 holes totalling 10,117m of reverse circulation drilling. This expansion reflects management's confidence in the target area following exceptional high-grade intersections from Stage 1 drilling.

Stage 2 Expansion Signals Growing Confidence
Program Scale and Scope
The Stage 2 drilling program demonstrates Marmota Ltd's Greenewood discovery is gaining substantial momentum. The company increased both drilling footprint and depth beyond initial parameters, expanding from 85 planned holes to 129 completed holes.
Total drilling extended from 8,500m to over 10,000m, providing enhanced opportunity to identify deeper mineralised zones. Samples from the expanded program are currently en route to Adelaide laboratories for processing.
Assay results are anticipated around the end of January 2025, though holiday season scheduling may influence final delivery timelines. The drilling expansion indicates management's strategic response to emerging geological data, suggesting the target area warrants more comprehensive evaluation than originally planned.
What Makes Stage 1 Results Exceptional?
Outstanding High-Grade Intersections
Earlier results from Stage 1 drilling at Marmota Ltd's Greenewood discovery delivered some of the most remarkable gold intersections recorded in the Gawler Craton region in recent years. The standout results include multiple thick, high-grade intervals that demonstrate substantial grade continuity.
Key thick intersections from Stage 1 include:
| Hole ID | Interval Start (m) | Interval Length (m) | Grade (g/t) |
|---|---|---|---|
| 25GWRC046 | 22 | 33 | 10.0 |
| 25GWRC099 | 49 | 22 | 5.1 |
| 25GWRC101 | 21 | 11 | 4.5 |
| 25GWRC112 | 21 | 18 | 3.2 |
Exceptional Single-Metre Grades
Individual metre samples revealed multiple intervals exceeding 20 g/t gold, with the highest assay reaching 109 g/t gold. These results illustrate the discovery's robust grade profile and highlight potential for developing a scalable resource base.
The presence of bonanza-grade intervals within broader mineralised zones suggests both grade and geological continuity. Furthermore, the consistency of high-grade results across multiple drill holes confirms the target's exceptional prospectivity.
"The Greenewood gold discovery is yielding spectacular results. Marmota has acted with remarkable speed to get Stage 2 of our maiden program underway so quickly," said Dr Colin Rose, Chairman.
Strategic Position in Gawler Craton
Regional Context and Infrastructure Advantages
Marmota Ltd's Greenewood discovery benefits from its strategic location within the established Gawler Craton gold belt. The project sits approximately 35km northwest of Aurora Tank and 30km northeast of the Challenger Gold Mine, positioning it within a proven mineralised corridor.
This proximity to existing deposits creates potential economies of scale for future development. Multiple gold deposits in close proximity enable companies to leverage shared drilling contractors, processing infrastructure, and development expertise in a more cost-effective manner.
Prior to Marmota's 2025 program, Greenewood had received only approximately 7,000m of drilling since discovery. This limited historical exploration makes recent achievements particularly significant in advancing what was previously an underexplored section of the gold belt.
Understanding Reverse Circulation Drilling
Educational Overview: RC Drilling Methods
Reverse circulation drilling represents a fundamental exploration technique widely used in the mining industry for initial resource evaluation. This method utilises dual-walled drill rods that circulate compressed air down the outer rod and back up through the inner rod.
The air circulation process forces rock cuttings directly back up the rods into a collection system, significantly reducing sample contamination compared to conventional drilling methods. For exploration companies, RC drilling offers substantial advantages in terms of cost-effectiveness and time efficiency during early discovery phases.
However, RC drilling enables companies to rapidly test geological targets while maintaining sample quality suitable for resource estimation. The method proves particularly valuable when testing multiple targets across large areas, as demonstrated in Marmota Ltd's Greenewood discovery program.
Development Timeline and Future Milestones
Laboratory Processing and Results Schedule
Current drilling samples are undergoing laboratory analysis in Adelaide, with assay results expected around late January 2025. These results will provide critical data for both extensional and in-fill drilling conducted during Stage 2, supporting potential future resource estimation work.
The Stage 2 program was specifically designed to combine extensional holes testing strike and depth extensions with in-fill holes required for resource definition. This dual approach reflects management's confidence in the deposit's continuity and their strategic planning for potential resource estimation.
"Greenewood is developing at phenomenal speed: we have now drilled our first 25,000m at Greenewood in less than 6 months, something that previously took 3 years to achieve at Aurora Tank," Dr Rose commented.
2026 Exploration Strategy
Management has indicated intentions to maintain the accelerated exploration pace throughout 2026. The rapid progression from discovery to comprehensive drilling program demonstrates operational effectiveness and suggests continued expansion if results remain positive.
In addition, the company's ability to mobilise and expand drilling campaigns quickly indicates strong operational capabilities and established contractor relationships, both critical factors for maintaining exploration momentum.

Investment Considerations
Multiple Value Drivers Emerging
Marmota Ltd's Greenewood discovery presents several compelling investment characteristics. The combination of high-grade early intersections, large unexplored footprint, and strategic location within the Gawler Craton creates multiple potential value drivers.
Strong early results across multiple drill holes confirm the target's gold prospectivity, while the drilling campaign remains in maiden phases, suggesting significant room for further discoveries as exploration areas expand.
Regional Synergies and Development Potential
The project's position near Aurora Tank and proximity to the former Challenger mine creates potential synergies for future development scenarios. Marmota's ability to leverage multiple deposits within the same region could support more robust development economics compared to standalone projects.
A maiden scoping study has commenced for Marmota's broader Gawler gold project, representing an important step toward evaluating potential development pathways. This study will assess how multiple deposits, including Greenewood, might support integrated development approaches.
Operational Excellence and Timeline Advantages
Marmota's demonstrated ability to rapidly mobilise drilling programs and achieve expanded results ahead of schedule differentiates the company from peers facing operational challenges. The completion of 25,000m of drilling in six months, compared to three years for equivalent programs at other projects, highlights exceptional operational execution.
Accelerated exploration timelines potentially reduce the window from discovery to development decisions, creating advantages for investors seeking exposure to exploration success with shorter development timeframes. Moreover, this operational efficiency positions the company favourably for continued exploration success throughout the remainder of 2025.
