Mammoth Minerals Launches Historic Diamond Drilling Campaign at Nevada Gold Project
Mammoth Minerals (ASX: M79) has commenced its first-ever diamond drilling program at the Excelsior Gold-Silver Project in Nevada, marking a significant milestone in the company's exploration efforts in a renowned gold-producing region.
Strategic Shift to Diamond Drilling Unlocks Critical Structural Insights
The company has strategically pivoted to a full diamond core drilling program from the originally planned reverse circulation (RC) drilling, enabling geologists to obtain critical structural data essential for understanding the high-grade mineralization controls. This approach will provide Mammoth with unprecedented geological detail at the Excelsior project, which historically produced 19,200oz at an impressive 41g/t Au from the Buster Underground Mine.
"It is evident from spending time on site and within the Buster Underground Mine area workings that structure plays a very significant role in the distribution and extent of the gold mineralisation across the 5km Buster Trend," explained Mammoth Minerals Managing Director Glenn Poole.
The drilling program aims to follow up on several high-grade intercepts from previous exploration campaigns, including:
| Hole ID | Intercept | Depth |
|---|---|---|
| 22_01 | 51.8m at 4.00g/t Au including 6.1m at 16.30g/t Au | from 39.6m |
| DB23 | 33.5m at 5.35g/t Au including 10.7m at 15.99g/t Au | from 41.2m |
| 22_02 | 32.0m at 2.45g/t Au including 6.1m at 10.00g/t Au | from 44.2m |
| EX2 | 24.4m at 3.62g/t Au including 9.2m at 7.99g/t Au | from 70.1m |
A second diamond drill rig is scheduled to arrive on site within two weeks to expedite the program, demonstrating the company's commitment to rapidly advancing the project.
Metallurgical Testing: Pathway to Production
Beyond defining the geometry and extent of gold-silver mineralization, the diamond drilling program will provide core samples for crucial metallurgical testing. This analysis will determine leaching characteristics and help establish processing pathways and potential metal recovery rates—essential data for future development studies.
The company has also completed channel sampling across the Blue Dick Underground Mine, which historically produced high-grade silver ore. With samples submitted for expedited assays, investors can anticipate news flow in the near term regarding silver potential at the project.
Additionally, property-wide magnetics and LIDAR surveys have commenced across the Excelsior Project, which will further enhance the company's understanding of the geological framework.
Understanding Diamond Drilling: Why It Matters to Investors
Diamond drilling represents a significant upgrade from reverse circulation drilling when defining precious metal deposits. While more expensive, diamond drilling provides intact core samples that allow geologists to:
- Measure precise angles of mineralized structures
- Identify controlling features of high-grade zones
- Conduct detailed metallurgical studies on intact ore samples
- Assess geotechnical parameters for future mining studies
For investors, this means more reliable resource definition and a clearer understanding of the project's economic potential. Companies that invest in diamond drilling often signal confidence in their projects and a commitment to detailed technical evaluation.
The Diamond Drilling Process
Diamond drilling utilizes a hollow drill bit embedded with industrial-grade diamonds to cut through rock and extract a cylindrical core sample. This method preserves the structural integrity of the rock, allowing geologists to observe:
- Orientation of mineral veins
- Rock types and boundaries
- Fault and fracture patterns
- Alteration zones around mineralization
These observations are particularly crucial in structurally complex deposits where the distribution of high-grade gold can be controlled by specific geological features. At Excelsior, understanding these controls could significantly enhance targeting efficiency and resource definition.
"By using diamond drilling we will be able to identify the specific controlling structures and measure with a high degree of accuracy the orientation and nature of those structures. This will allow us to optimise the orientation of the drilling to target the high-grade structures and rapidly assess the scale of the mineralisation," noted Poole.
Portfolio Optimization: Focusing on US Gold Assets
Mammoth is strategically positioning itself as a US-focused gold explorer, concentrating resources on its Nevada and South Dakota gold assets. As part of this strategic focus, the company has negotiated a deferral of the consideration payment for its Skyline Copper Project in Newfoundland, Canada. The deferred consideration, comprising A$100,000 and 25,000,000 Mammoth shares, is now due by November 30, 2025.
This strategic move follows the company's recent divestment of its Paterson Project in Western Australia to London-listed Cloudbreak PLC, resulting in a holding currently valued at approximately A$5.0 million. These portfolio optimization efforts align with Mammoth's stated commitment to monetizing non-core assets to support the development of its US gold projects.
Timeline and Next Steps
Investors can expect a steady stream of news flow in the coming months as Mammoth advances multiple work streams:
- Ongoing diamond drilling results from the Excelsior project
- Metallurgical test results determining processing options
- Assay results from Blue Dick Underground Mine sampling
- Results from property-wide magnetics and LIDAR surveys
- Potential corporate developments regarding non-core assets
