Strategic Asset Divestment Strengthens Focus on High-Grade Nevada Gold
Mammoth Minerals Limited (ASX: M79) has successfully completed the divestment of its non-core Paterson Project to Cloudbreak Discovery PLC (LSE: CDL), marking a significant strategic milestone. This portfolio streamlining comes as the company reports exceptional progress with its ongoing RC drilling Mammoth Minerals Ltd programme at the high-grade Excelsior Springs Gold-Silver Project in Nevada.
The timing of this announcement reflects Mammoth's clear strategic direction: divest non-core assets while accelerating exploration at its flagship Nevada project. Previous drilling has delivered outstanding intercepts including 51.8m at 4.00g/t Au and 33.5m at 5.35g/t Au.

Deal Structure Provides Substantial Upside Exposure
The completed divestment of the Paterson Copper-Gold Project in Western Australia to Cloudbreak Discovery represents more than just an asset sale. Furthermore, it's a strategic repositioning that affirms Mammoth's commitment to becoming a dedicated USA precious metals explorer.
Milestone-Based Share Structure
The revised agreement with Cloudbreak provides Mammoth with substantial upside exposure through a milestone-based share structure:
| Consideration Type | Shares | Conditions |
|---|---|---|
| Completion Shares | 100,000,000 | Immediate upon settlement |
| Tranche 1 Deferred | 57,500,000 | Heritage surveys, mapping, sampling |
| Tranche 2 Deferred | 57,500,000 | Soil sampling, track construction |
| Tranche 3 Deferred | 57,500,000 | Ground IP/magnetics surveys |
| Tranche 4 Deferred | 57,500,000 | 3,000m drilling programme completion |
Total Potential Consideration: 330,000,000 Cloudbreak shares
This structure ensures Mammoth maintains exposure to the Paterson Project's exploration upside while freeing capital and management focus. The milestone-based payments incentivise Cloudbreak to advance exploration activities, potentially creating additional value for Mammoth shareholders.

RC Drilling Campaign Delivers Exceptional Productivity at Excelsior
The real excitement centres on Mammoth's ongoing RC drilling programme at the Excelsior Springs Gold-Silver Project in Nevada's world-class Walker Lane trend. In addition, the company has achieved remarkable drilling productivity, with 11 holes completed for 1,471m already submitted for analysis.
Operational Improvements Drive Efficiency
The rc drilling campaign represents a significant operational improvement over previous programmes:
• 11 holes completed totalling 1,471m in recent weeks
• Combined total of over 3,350m drilled across the Buster Trend to date
• Assay results expected within three weeks from initial RC programme
• Nearly matching entire 2025 drilling output in just weeks of 2026 activity
This productivity surge addresses previous operational challenges where less than 20% of planned drilling was achieved with diamond rigs. Consequently, the RC rig's consistent high-metre performance allows Mammoth to efficiently test geological targets across the Buster Mine zone.
High-Grade Intercepts Define Resource Potential
The drilling targets significant portions of the Buster Mine zone that remain untested, with known mineralised zones open along strike and down-dip. For instance, previous drilling has established exceptional high-grade potential:
• 51.8m at 4.00g/t Au from 39.6m including 6.1m at 16.30g/t Au from 42.7m
• 33.5m at 5.35g/t Au from 41.2m including 10.7m at 15.99g/t Au from 41.2m
• 24.4m at 3.62g/t Au from 70.1m including 9.2m at 7.99g/t Au from 79.2m
• 32.0m at 2.45g/t Au from 44.2m including 6.1m at 10.00g/t Au from 45.7m
• 14.4m at 4.33g/t Au from 117.0m including 3.1m at 19.10g/t Au from 119.36m
Understanding RC Drilling: A Cost-Effective Exploration Tool
Reverse Circulation (RC) drilling represents a crucial exploration technique that balances cost-effectiveness with geological accuracy. Unlike diamond drilling, which produces solid core samples, RC drilling uses compressed air to bring rock chips to the surface through a dual-wall drill pipe system.
Why RC Drilling Matters for Investors
However, RC drilling provides several advantages over traditional methods:
- Cost efficiency: Typically 30-50% less expensive than diamond drilling
- Speed advantage: Higher drilling rates enable rapid target testing
- Sample quality: Provides representative samples for accurate assaying
- Optimal for initial resource definition: Perfect for extending known mineralised zones
For Mammoth, the shift to RC drilling has transformed operational efficiency, enabling the company to test multiple targets across the Buster Trend. This approach is particularly valuable when extending known high-grade zones where geological continuity has been established.
Strategic Positioning in Nevada's Walker Lane Trend
Mammoth's focus on the Excelsior Springs Gold-Silver Project positions the company within Nevada's prolific Walker Lane trend. Furthermore, this world-class gold-producing region hosts numerous major deposits and provides several strategic advantages.
Geological Setting and Resource Potential
The project's location offers considerable benefits:
• Walker Lane trend hosting multiple world-class gold deposits
• Shallow mineralisation with high-grade intercepts from surface
• Open pit mining potential based on intercept depths and grades
• 80% earning opportunity providing substantial project control
Path to Initial Resource Estimate
The current RC drilling Mammoth Minerals Ltd campaign aims to underpin an initial Mineral Resource estimate for Excelsior. This represents a crucial milestone for the project, as over 3,350m of drilling completed and additional RC holes pending assays build a comprehensive database.
The combination of consistent high-grade intercepts and extensional drilling success positions Excelsior as a potential near-term resource development opportunity. Consequently, this places the project in one of the world's premier gold districts.
Investment Thesis: Pure-Play USA Gold Strategy Taking Shape
Mammoth's strategic evolution into a dedicated USA gold and silver explorer creates a compelling investment proposition for several key reasons. Moreover, the focused approach enhances operational efficiency and capital allocation effectiveness.
Focused Asset Portfolio Benefits
The Paterson divestment eliminates geographic diversification complexity, allowing management to concentrate resources on Nevada's proven gold potential. This focus enhances operational efficiency and capital allocation effectiveness.
High-Grade Resource Development Pathway
Excelsior's consistent high-grade intercepts suggest potential for a significant shallow gold resource in a tier-one mining jurisdiction. In addition, the current drilling campaign directly supports initial resource estimation, representing a key value inflection point.
Operational Momentum Building
The RC drilling programme's exceptional productivity demonstrates improved operational execution. Completing nearly a full year's drilling in weeks shows management's ability to deliver efficient exploration programmes.
Nevada Mining Jurisdiction Advantages
Furthermore, Nevada offers several competitive advantages:
• Stable regulatory environment with established mining codes
• Excellent infrastructure supporting mining operations
• Skilled workforce and established service provider network
• Favourable taxation and royalty framework
