Mammoth Minerals Nevada Drilling Results Reveal Significant Gold Extensions

Mammoth Minerals Limited (ASX: M79) has delivered impressive Mammoth Minerals Nevada drilling results from its ongoing reverse circulation (RC) program at the Buster Gold Trend within Nevada's Excelsior Gold-Silver Project. The latest assays reveal multiple significant intercepts that not only validate the company's Carlin-type deposit model but also expand the known mineralised footprint both laterally and at depth.

The standout results include 13.72m at 1.15g/t Au from a new area of mineralisation identified 100 metres west of previous drilling, and 7.62m at 2.1g/t Au from 219.51m down-dip—extending mineralisation over 100 metres below previous drilling with the system remaining open below 180m depth.

Multiple High-Grade Intercepts Validate Carlin-Type Model

The RC drilling campaign has delivered a series of compelling intercepts that reinforce the broad, shallow nature of the Buster mineralisation. Furthermore, these Mammoth Minerals Nevada drilling results demonstrate the expanding potential of the project across multiple zones.

Key Results Summary

Managing Director Commentary

"The thick, shallow intercepts we are seeing from surface support the working geological model and, with most of the drilling completed to date only targeting the top 150m, Buster remains very much open both down-dip and along strike." – Glenn Poole, Managing Director

The step-out drilling to the west has proven particularly encouraging, identifying an expanding zone of mineralisation well beyond previously completed drilling. This discovery not only provides confidence in mineralisation continuity but also creates immediate follow-up opportunities.

Understanding Carlin-Type Gold Deposits

What makes Carlin-Type deposits special?

Carlin-Type Gold Deposits (CTGD) represent one of Nevada's most significant deposit styles, responsible for over 20 million ounces of gold production across the Walker-Lane region. These deposits require specific geological conditions:

• Structural Architecture: Deep fault systems that act as fluid pathways
• Permeable Host Rocks: Typically limestone that can absorb mineral-rich fluids
• Heat Source: Nearby intrusive structures driving hydrothermal systems
• Chemical Alteration: Limestone dissolution creating space for microscopic gold within pyrite

Why this matters for investors: CTGDs often host large-scale, bulk-tonnage mineralisation that can support long-life mining operations. The evidence from Mammoth's drilling—including abundant chemical weathering, highly altered limestone, and significant fault structures—supports this favourable deposit model at Buster.

Expanding Discovery Pipeline

Imperial Project Acquisition

Beyond Buster, Mammoth is advancing the recently acquired Imperial Project, which brings drill-ready targets with impressive historical results. In addition, these results complement the promising Mammoth Minerals Nevada drilling results from the main Buster project area.

Historical Imperial Highlights:

• 12.19m at 4.74g/t Au from 32m (including 3.05m at 15.61g/t Au)
• 10.67m at 2.24g/t Au from surface
• 6.10m at 2.46g/t Au from 9.14m

Underground sampling has returned exceptional grades:

• 0.76m at 237.48g/t Au
• 1.22m at 15.77g/t Au
• 0.91m at 19.13g/t Au

Blue Dick Prospect Development

Surface sampling and mapping campaigns are underway at Blue Dick to delineate parallel gold and silver-rich trends. Historical grab samples from this area have returned grades up to 2,340 g/t Ag and 7.4 g/t Au, though these require validation through systematic sampling.

Strategic Positioning and Future Catalysts

Immediate Opportunities:

1. Follow-up drilling on the new western mineralisation zone (MEXRC2601)
2. Depth extensions below 180m where mineralisation remains open
3. Imperial Project drilling following permit approval
4. Blue Dick systematic sampling results

Timeline Expectations:

• Further RC drilling results from Buster: Coming weeks
• Blue Dick sampling assays: Coming weeks
• Imperial underground mapping results: Coming weeks

District-Scale Potential:
The 7km-long Buster Trend combined with the Imperial acquisition and Blue Dick prospects positions Mammoth across a significant mineralised corridor. The company's 135km² landholding in Nevada's proven Walker-Lane region provides substantial exploration upside.

Investment Thesis: Nevada Gold Exposure with Near-Term Catalysts

Key Investment Highlights:

Financial Position: With ongoing drilling and multiple work programs, investors should monitor quarterly reports for funding requirements and program advancement.

Operational Excellence: The shift to RC drilling has delivered improved sample recoveries and productivity, particularly in highly altered material typical of Carlin-type systems.

Why Investors Should Follow Mammoth Minerals

Mammoth Minerals has positioned itself as a focused Nevada gold explorer with several compelling advantages. Consequently, the latest Mammoth Minerals Nevada drilling results reinforce the company's strategic positioning in this proven mining district.

1. Proven Geology: The Carlin-type deposit model at Buster is supported by geological evidence including intense alteration, fault structures, and broad mineralised corridors.

2. Scalable Resource Potential: Multiple 30+ metre intercepts from surface suggest significant bulk-tonnage potential across the 7km Buster Trend.

3. District Consolidation: The Imperial acquisition and extensive claim staking demonstrate strategic positioning across a mineralised district.

4. Near-Term Catalysts: Multiple work programs across three prospects ensure regular newsflow and discovery potential.

5. Experienced Management: Led by Managing Director Glenn Poole, the team has demonstrated systematic approach to exploration and geological understanding.

Key Takeaway:

Mammoth Minerals has established itself as a significant Nevada gold explorer with multiple discovery opportunities across a district-scale land position. The expanding Buster mineralisation, combined with high-grade Imperial targets and Blue Dick silver potential, provides investors with exposure to Nevada's proven gold endowment through a focused, well-managed exploration program.

The combination of broad, shallow gold intercepts, expanding mineralised footprint, and multiple drill-ready targets positions Mammoth as a compelling Nevada gold story with substantial near-term catalyst potential. However, the ongoing success of these programs will depend heavily on continued positive Mammoth Minerals Nevada drilling results from the various prospect areas.
