Marmota Ltd Gold Discovery Delivers Bonanza Grades Across 900 Metres

Marmota Strikes Gold: Bonanza-Grade Discovery Extends Across 900-Metre Zone

Marmota Limited (ASX: MEU) has announced its second batch of exceptional assay results from the Greenewood gold discovery in South Australia's Gawler Craton. This remarkable Marmota Ltd gold discovery confirms what could be one of the region's most significant gold findings since Challenger Mine in 1995.

The latest results showcase spectacular intersections of 44 metres at 2.3 g/t gold and 36 metres at 3.0 g/t gold, with individual samples reaching bonanza grades of up to 24 g/t gold. These extraordinary results demonstrate the exceptional potential of this emerging gold system.

The November-December 2025 drilling programme has revealed a nearly-continuous high-grade mineralised system extending across approximately 900 metres of strike length. Most remarkably, the discovery remains open in all directions, setting the stage for a major follow-up programme scheduled to commence in March 2026.

Exceptional Results Define World-Class Discovery

The Stage 2 drilling results have exceeded even the company's Stage 1 discoveries, delivering some of the thickest and highest-grade intersections yet recorded at Greenewood. Furthermore, these results continue to validate the significant potential of this emerging gold system.

Outstanding Thick Intersections

The latest drilling programme has delivered exceptional broad intersections that highlight the scale of this discovery:

High-Grade Bonanza Intersections

In addition to these broad zones, the discovery continues to deliver exceptional bonanza-grade gold intersections within these intervals:

• 4m at 24 g/t gold within the 32m intersection
• 4m at 18 g/t gold within the 36m intersection
• 4m at 16 g/t gold within the 44m intersection
• 4m at 15 g/t gold within a 20m intersection
• 4m at 12 g/t gold within a 32m intersection

These results complement the Stage 1 standout intersection of 33m at 10 g/t gold from 22m downhole, which included individual 1-metre samples up to 109 g/t gold. The consistency of high-grade results across multiple drilling phases reinforces the robust nature of this Marmota Ltd gold discovery.

Discovery Extends Beyond Historical Drilling

One of the most significant developments is the extension of high-grade mineralisation into areas previously considered barren. Historical drilling conducted in 2017 by previous owners found the north-eastern extension to be non-economic.

However, Marmota's slightly deeper holes have uncovered some of the discovery's best intersections in this exact area. This breakthrough demonstrates the value of systematic exploration programmes and deeper drilling.

Cross-section 73 provides a compelling example of this success. Historical holes from 2017 (17GWRC001-006) were too shallow and missed the thick gold intersections underneath, including the spectacular 36m at 3.0 g/t gold starting from 64m downhole.

Similarly, Cross-section 71 shows historical Hole 17GWRC007 stopping at 42m and appearing barren. Marmota extended that hole and subsequently yielded 32m at 3.2 g/t gold from 56m downhole.

"Stage 2 drilling has produced even longer intersections than Stage 1, with thick intersections featuring across the discovery. The programme has clearly delineated a nearly-continuous high-grade mineralised system," noted company management.

Understanding Gold Mineralisation: What Makes Greenewood Special?

Gold mineralisation refers to the concentration of gold within rock formations to economically viable levels. At Greenewood, the gold occurs within the late Archaean Mulgathing Complex, comprising layered sedimentary rocks interspersed with Banded Iron Formations (BIF), chert, carbonates and calcium-silicate minerals.

Why This Matters to Investors

The geological setting mirrors that of other major Gawler Craton gold deposits, including the Challenger Mine which produced over one million ounces. The combination of high grades, excellent continuity, and shallow depth from surface creates the potential for low-cost, open-pit mining operations.

Moreover, the relatively shallow nature of the mineralisation significantly reduces potential extraction costs compared to deep underground operations. This factor enhances the economic attractiveness of the Marmota Ltd gold discovery.

Key Technical Terms Explained

• g/t: Grams per tonne – the standard measure of gold grade
• Bonanza grade: Exceptionally high gold grades, typically above 10 g/t
• Strike length: The horizontal extent of mineralisation
• Downhole depth: Measured distance along the drill hole

What's Next for the March 2026 Expansion Programme?

With the discovery remaining open in all directions, Marmota has scheduled a major follow-up RC drilling programme to commence in March 2026. The primary objective involves advancing the Greenewood discovery to the south in an area known as Mainwood.

This expansion has the potential to extend the strike of the system to approximately 2 kilometres, which would substantially increase the overall resource potential. The systematic approach to exploration continues to yield exceptional results.

Upcoming Catalysts

Several key milestones will drive investor interest in the coming months:

1. 1-metre split assays from Stage 2 drilling (expected soon)
2. March 2026 drilling programme targeting southern extensions
3. Resource definition drilling across the 900-metre strike length
4. Maiden resource estimate incorporating all drilling results

The company's maiden scoping study for the broader Gawler Gold project commenced in November 2025. This positions Marmota to potentially advance multiple deposits simultaneously, creating significant operational synergies.

Strategic Investment Thesis: Arc of Gold Portfolio

Greenewood forms part of Marmota's exceptional "Arc of Gold" portfolio along the flanks of the major 'Y'-shaped gravity anomaly in the northwest Gawler Craton. This strategic positioning includes multiple deposits that enhance the overall value proposition.

Deposit Portfolio Comparison

Proximity advantage: Greenewood sits just 35km northwest of the flagship Aurora Tank deposit and 30km northeast of the historic Challenger Mine. This creates obvious economies of scale and scope for future development across the portfolio.

Financial Context

The comprehensive exploration programme demonstrates significant commitment to advancing this discovery:

• Stage 1 drilling: 146 holes, 15,480 metres completed August 2025
• Stage 2 drilling: 126 holes, 10,117 metres completed December 2025
• Total investment: Over 25,500 metres across 272 RC holes
• Coverage: Comprehensive testing across 900-metre strike length

Investment Fundamentals: Understanding the Gawler Craton

The Gawler Craton represents one of Australia's most prospective but underexplored gold regions. This ancient geological structure formed over 1.5 billion years ago and hosts several world-class mineral deposits.

Regional Context

The region's geological history created ideal conditions for gold concentration through multiple geological events. The late Archaean period saw the formation of layered rock sequences that later experienced folding, faulting, and mineral-rich fluid movement.

Challenger Mine precedent: The nearby Challenger Mine produced over one million ounces of gold between 2002-2013, demonstrating the commercial viability of Gawler Craton deposits. Similar geological settings at Greenewood suggest comparable potential for this Marmota Ltd gold discovery.

Exploration Advantages

The relatively shallow depth of mineralisation at Greenewood offers significant advantages. With significant intersections starting from just 12 metres downhole, this indicates potential for low-cost open-pit extraction.

This contrasts favourably with many deep underground operations, offering potentially superior economics. The shallow nature reduces both extraction costs and development complexity.

Why Should Investors Follow Marmota Limited?

The latest Greenewood results position Marmota as a premier gold discovery story in one of Australia's most prospective but underexplored regions. Several factors make this a compelling investment opportunity.

Scale and Grade Combination

The discovery delivers the rare combination of exceptional grades (up to 109 g/t gold) with substantial widths (up to 44 metres). This creates the foundation for a potentially significant gold deposit with robust economics.

Furthermore, the consistency of these results across multiple drilling phases demonstrates the reliability of the mineralised system. This consistency reduces geological risk for future resource development.

Exploration Upside

With mineralisation open in all directions and only 7,000 metres of historical drilling prior to Marmota's programme, the discovery remains in its early stages. The substantial expansion potential presents significant upside for investors.

Additionally, the success in extending mineralisation beyond previously barren areas suggests considerable untapped potential. This factor enhances the long-term value proposition of the project.

Strategic Location

Positioning within the proven Gawler Craton gold belt, near infrastructure and established mining operations, reduces development risks. The proximity to the historic Challenger Mine provides valuable operational precedent.

Moreover, the regional infrastructure and established mining culture in South Australia support efficient project development. These factors reduce both technical and regulatory risks.

Management Execution

The systematic approach to expanding the discovery beyond historical drilling demonstrates strong technical capability. The company's ability to identify mineralisation in previously overlooked areas showcases exceptional geological expertise.

In addition, the strategic timing of drilling programmes and efficient capital allocation reflect experienced management. This execution capability enhances investor confidence in future programme success.

Portfolio Diversification

Beyond Greenewood, Marmota maintains interests in uranium (Junction Dam) and additional gold prospects, providing multiple value drivers. This diversification reduces single-asset risk whilst maintaining precious metals exposure.

"The geological characteristics and mineralisation style at Greenewood are highly encouraging for resource development. The continuity of high grades across multiple drilling intersections suggests a robust mineralised system with significant expansion potential," notes the technical review.

Next Steps and Timeline

The March 2026 drilling programme represents a critical milestone for expanding the Greenewood discovery. The company aims to test potential extensions to the south, which could double the current strike length.

This expansion would significantly enhance the resource potential and establish Greenewood as a major regional discovery. The systematic approach continues to yield exceptional results that exceed expectations.

Key milestones ahead:

• February 2026: 1-metre split assay results from Stage 2
• March 2026: Commencement of major expansion drilling
• Mid-2026: Maiden resource estimate incorporating all results
• Late 2026: Preliminary economic assessment completion

The combination of world-class intersections, substantial expansion potential, and strategic positioning within a proven gold district makes Marmota compelling. With the March 2026 drilling programme targeting potential 2-kilometre strike extensions, investors should closely monitor this exceptional exploration story as it continues to validate the significance of the Marmota Ltd gold discovery.
