Mammoth Minerals Advances Towards Maiden Resource with High-Grade Blue Dick Results

High-Grade Surface Results Spotlight Blue Dick’s Growth Potential

Mammoth Minerals (ASX:M79) has unveiled a string of impressive high-grade assays from surface and channel sampling at its Blue Dick prospect within the Excelsior Springs Project in Nevada. Highlights include gold grades reaching 39.8g/t alongside silver levels of 251g/t and notable base metals such as copper, lead, and antimony; all critical minerals on the US strategic list. These results confirm multiple parallel mineralised trends, expanding the project’s footprint and underscoring substantial growth potential adjacent to existing zones.

The company’s Managing Director Glenn Poole emphasised the significance of these findings, noting the consistency of gold and critical minerals across the sampled areas. The Blue Dick results add a new dimension to Mammoth’s portfolio, complementing the adjacent Buster Gold Trend and reinforcing the district-scale opportunity in this part of the Walker Lane tectonic zone.

These latest surface assays build on Mammoth’s recent staking and acquisition activities, including the Imperial Gold Mine option, which collectively have expanded the project’s landholding to 135km². The ongoing sampling campaign aims to delineate drill-ready targets, with further assay results pending to validate the continuity of these mineralised trends.

Buster Drilling Confirms Scale and Supports Maiden Resource

Meanwhile, reverse circulation (RC) drilling at the Buster Gold Trend continues to deliver encouraging results that support a Carlin-type deposit model. The program has tested approximately 1.3km of a 7km mineralised corridor, with mineralisation remaining open along strike and down-dip. Significant intercepts include gold grades up to 4.04g/t over 1.53m, highlighting the potential for a sizeable resource.

Mammoth is now compiling the drilling database for submission to independent consultants, aiming to deliver its maiden Mineral Resource Estimate (MRE) and Exploration Target by Q3 2026. This milestone is pivotal, marking a transition from exploration to resource definition and positioning the company for potential development discussions.

The scale potential of the Buster Trend is particularly noteworthy given the limited drilling coverage to date. The 7km corridor remains largely underexplored, preserving substantial upside for resource expansion as systematic drilling progresses.

Strategic Location and Critical Minerals Enhance Project Appeal

Mammoth’s Excelsior Springs Project benefits from a strategic location just 75km from Blackrock Silver’s Tonopah West Project, which boasts an 8.29Mt resource grading 462g/t silver equivalent. This proximity situates Mammoth within a prolific precious metals district, enhancing the potential market interest in its discoveries.

Importantly, the presence of critical minerals such as antimony, lead, copper, and zinc alongside gold and silver adds a valuable dimension amid growing demand for these commodities in clean energy and technology sectors. The combined presence of precious and critical minerals could influence future project economics and stakeholder interest.

Exploration efforts are ongoing, with Mammoth planning additional rock chip and channel sampling at Blue Dick and across the newly acquired Imperial Gold Mine area. These programs aim to refine drill targets and expand the understanding of mineralisation controls and distribution.

These developments follow Mammoth’s recent Nevada Gold Footprint with Drilling and Imperial Acquisition, which expanded its tenure and exploration pipeline, and build on the Expanding Gold Zones at Nevada’s Excelsior Project where drilling reinforced the Carlin-type model and district-scale potential.
