Mammoth Minerals Expands Nevada Gold Portfolio with Imperial Acquisition

Strategic Nevada Gold District Consolidation

Mammoth Minerals Limited (ASX: M79) has strengthened its Nevada portfolio with the acquisition of the Imperial Gold Mine, a high-grade former producer located just 5km from the company's flagship Excelsior Springs project. This Mammoth Minerals Nevada gold acquisition consolidates 135km² of prospective ground in what appears to be an emerging district-scale Carlin-type gold system.

The Imperial Gold Mine brings immediate exploration upside with exceptional historical results including underground channel sampling of 237.48g/t Au and significant drilling intercepts up to 28.96m at 2.23g/t Au. Furthermore, with mineralisation starting at surface and tested to only 150m depth, the acquisition provides substantial growth potential in a proven mining district.

Key Strategic Insight

"This acquisition represents our largest land consolidation to date, expanding from 15km² to 135km² in less than nine months. We now control what appears to be a district-scale Carlin-type system with multiple high-grade targets." – Glenn Poole, Managing Director

High-Grade Results Validate Acquisition Strategy

The Imperial Gold Mine has delivered some of the most impressive gold grades seen in Mammoth's Nevada operations. Additionally, underground channel sampling has produced exceptional results, with the highest grade reaching 237.48g/t Au over 0.76m (IUA175).

Outstanding Underground Channel Results:

• 237.48g/t Au over 0.76m (IUA175)
• 47.18g/t Au over 0.76m (IUA128)
• 19.13g/t Au over 0.91m (IUA120)
• 15.77g/t Au over 1.22m (IUA10)

Significant Historical Drill Intercepts:

• 28.96m at 2.23g/t Au from 3.05m (IR-29)
  • Including 3.05m at 9.95g/t Au

• 13.72m at 4.74g/t Au from 30.48m (IR-4)
  • Including 3.05m at 17.20g/t Au

• 10.67m at 2.48g/t Au from surface (IR-22)
• 32.0m at 1.09g/t Au from 48.77m (RRP-17)

Historical production records indicate approximately 10,000 tonnes of ore was mined at grades exceeding 15g/t Au during the 1920s-1930s. However, operations ceased only due to World War II.

Understanding Carlin-Type Gold Deposits: A Premier Deposit Class

Carlin-type gold deposits represent one of Nevada's most valuable mineralisation styles, responsible for making Nevada America's largest gold-producing state. These deposits form when gold-bearing fluids interact with specific carbonate host rocks, creating large tonnage, bulk-mineable resources.

What makes Carlin-type deposits attractive to investors:

• Large scale potential: Often contain millions of ounces
• Predictable metallurgy: Established processing methods
• Long mine life: Typically support decades of production
• Proven economics: Multiple world-class operations in Nevada

Independent geological confirmation that Imperial hosts Carlin-style mineralisation positions the project within this premier deposit class. Consequently, this provides a clear exploration blueprint based on Mammoth's experience at nearby Excelsior Springs.

Key Characteristics of Carlin-Type Systems

Carlin-type deposits occur in sedimentary rocks where hot, mineral-rich fluids have altered limestone and other carbonate rocks. Gold occurs as microscopic particles within altered rock, making these deposits suitable for large-scale, low-cost heap leach processing.

The deposits often extend over large areas both horizontally and vertically, creating the potential for multi-million ounce resources. In addition, this characteristic makes them particularly attractive for systematic exploration programs across district-scale areas.

District-Scale Consolidation Creates Competitive Advantage

Mammoth's strategic land consolidation has created a first-mover advantage in what appears to be a district-scale mineral system. The company has increased its Nevada landholding from 15km² to 135km² in less than nine months through systematic staking and acquisition.

Strategic Benefits of Scale:

• Contiguous land package connecting Excelsior Springs and Imperial
• Multiple exploration targets across a unified geological system
• Exploration synergies between projects
• District-scale resource potential

The newly staked ground between projects contains numerous historical workings and alteration features visible in satellite imagery. Furthermore, this suggests extensive mineralisation continuity across the district.

Regional Geological Context

The Imperial project area is underlain by Cambrian age limestone, siltstone, shale and quartzite with lesser Tertiary age volcanics. The favourable host rocks occur in the upper Campito formation and middle Poleta formation.

Multiple fault sets appear closely related to mineralisation, with the Imperial Fault traceable on surface for approximately 1,300m. For instance, this consists of at least three separate strands of near-vertical structures.

Commercial Terms Provide Measured Entry

The Imperial acquisition follows a structured earn-in model that balances opportunity with risk management. Mammoth has entered into an exclusive option to earn 100% of the Imperial Gold Mine through a phased expenditure program.

Phase 1 Requirements:

• US$50,000 initial option payment within 60 days
• US$500,000 annual expenditure (Years 1-4)
• US$1,000,000 annual expenditure (Years 5-6)

Earn-In Completion:

• 100% ownership upon US$4,000,000 total expenditure
• 3% net smelter royalty retained by vendor
• 1% NSR buyback option for US$1,500,000 (2-year window)

This structure allows Mammoth to systematically de-risk the asset while maintaining flexibility for accelerated development. However, if results warrant increased investment, the company can accelerate development accordingly.

Near-Term Catalyst Pipeline Strengthens Investment Case

Mammoth has outlined an aggressive near-term exploration program designed to rapidly advance multiple projects. Moreover, this program covers the entire consolidated Nevada landholding.

Immediate Work Programs:

1. Underground mapping and sampling at Imperial
2. Surface mapping and sampling across Blue Dick Silver trends
3. Continued RC drilling at Excelsior Springs Buster Trend
4. Regional targeting across the consolidated land package

Expected Newsflow (Coming Weeks):

• RC drilling assay results from Excelsior Springs
• Blue Dick Silver and Gold sampling results
• Imperial underground mapping and sampling results
• Integrated exploration program for district-scale targeting

This pipeline of results provides multiple catalysts for share price re-rating. Consequently, the district-scale story will unfold through systematic exploration across the expanded land position.

Investment Thesis: District-Scale Discovery Potential in Tier-1 Jurisdiction

The Mammoth Minerals Nevada gold acquisition has positioned the company at the centre of what could emerge as Nevada's next significant gold district. The combination of high-grade historical production, large-scale land consolidation, and proven Carlin-type mineralisation creates a compelling investment narrative.

Key Investment Drivers:

• Proven high-grade potential with grades up to 237g/t Au
• Large-scale resource upside across 135km² of consolidated ground
• Established infrastructure and mining-friendly jurisdiction
• Multiple exploration targets providing portfolio diversification
• Experienced management team with Nevada expertise

The Imperial acquisition validates Mammoth's district-scale consolidation strategy while providing immediate high-grade targets. Furthermore, this enables rapid resource growth potential.

Risk Considerations

• Historical data requires verification through modern exploration
• Early-stage projects with no current resource estimates
• Exploration success not guaranteed despite encouraging results
• Nevada regulatory and permitting requirements
