Mammoth’s Blue Dick Expansion Raises Questions on Resource Scale and Next Steps

Exceptional Sampling Results Expand Blue Dick Trend

Mammoth Minerals Limited (ASX – M79) has announced a major step forward in its exploration of the Excelsior Gold-Silver Project in Nevada, with recent sampling extending the high-grade polymetallic Blue Dick Trend to nearly 3 kilometres in strike length. The company reported outstanding rock chip and channel sampling results, including silver grades as high as 5,980 grams per tonne and gold up to 10.25 grams per tonne, alongside significant copper, antimony, lead, and zinc credits.

These results underscore the polymetallic nature of the mineralisation and suggest a potentially substantial mineralised system. The initial sampling program was designed to assess the scale and character of mineralisation before embarking on more detailed mapping and sampling campaigns.

Advanced Geophysical and Mapping Work Underway

Complementing the sampling, Mammoth completed a high-resolution LiDAR survey across the Blue Dick Trend, which has identified numerous additional surface disturbances such as historical pits and underground workings. These newly identified features represent promising targets for follow-up exploration.

Further, petrophysical analysis is in progress to better understand the geophysical signatures of the mineralisation, which will inform upcoming magnetic surveys. These geophysical efforts aim to refine structural interpretations and improve targeting precision for future drilling.

Drilling Progress and Broader Project Context

While no drilling results have yet been reported for the Blue Dick Trend itself, diamond drilling continues across the nearby Buster Gold Trend, with multiple samples submitted for assay and initial results expected imminently. This drilling is intended to clarify the geometry and controls on mineralisation, supporting the delineation of a Mineral Resource Estimate.

Mammoth’s strategic focus on the USA gold sector is reflected in its option to earn up to 80% of the Excelsior Project, a significant holding within the prolific Walker Lane tectonic zone known for hosting multi-million-ounce gold deposits. Historical exploration and production data, although limited and partially unverified, provide a solid foundation for Mammoth’s ongoing work.

Outlook and Strategic Implications

The combination of exceptional sampling grades, expanded strike length, and advanced geophysical surveys positions Mammoth Minerals well to unlock the value of the Excelsior Project. The company’s methodical approach, integrating surface sampling, geophysical targeting, and diamond drilling, reflects a disciplined exploration strategy aimed at underpinning future resource development.

Investors and industry watchers will be keenly awaiting the forthcoming assay results from the Buster Gold Trend drilling and the interpretation of geophysical data, which together will provide critical insights into the project’s potential scale and economic viability.
