Black Mammoth Unearths 2,610 g/t Silver in Historic Nevada District

VANCOUVER, BC – January 30, 2026 – Junior explorer Black Mammoth Metals Corporation has announced exceptional assay results from its West Reveille property in Nevada, including rock chip samples grading as high as 2,610 grams per tonne (g/t) silver. The discovery, located in a historic mining district largely untouched by modern exploration, confirms the presence of significant high-grade mineralization and energizes the company’s aggressive growth strategy in the American West.

The results from a recent reconnaissance sampling program not only revealed bonanza-grade silver but also significant concentrations of associated base metals, including high levels of lead, zinc, and copper. This polymetallic discovery breathes new life into the Reveille Mining District, a primary silver camp that dates to the 1870s, suggesting that substantial wealth may have been left behind by old-time prospectors.

Waking a Sleeping Giant: Reveille's Historic Silver Veins

The reported grade of 2,610 g/t silver is exceptionally high by industry standards. For context, many commercially viable silver mines operate on grades well below 500 g/t, making this surface discovery a compelling target for follow-up work. The high-grade samples were taken from a mineralized alteration zone with an approximate strike length of two kilometers, indicating the potential for a large-scale system. The mineralization appears within silicified rhyolite, limestone, and quartz veins at the contact zones between younger volcanic rocks and older Paleozoic sediments.

The West Reveille property, comprising 32 unpatented lode claims over 267 hectares, is situated in a region with a storied past. The Reveille district was a hive of activity in the late 19th century, with miners extracting high-grade, near-surface silver and lead ore. However, like many historic camps, modern exploration techniques have been sparsely applied. Black Mammoth’s recent work, which involved detailed geological mapping and systematic rock chip sampling, is one of the first modern efforts to reassess the district’s potential using current geological models. The company's findings suggest the historic miners may have only scratched the surface, leaving deeper or less obvious deposits undiscovered.

The 'Mammoth' Strategy in Action

This high-grade discovery serves as a powerful validation of Black Mammoth's ambitious corporate strategy. Since early 2024, the company has engaged in a rapid-fire acquisition campaign, assembling a vast and diverse portfolio of mineral properties across the western United States. The company has secured 100% interest in over a dozen projects in Nevada, Arizona, Idaho, New Mexico, and California, targeting a wide range of commodities from gold and silver to copper and rare earth elements.

This aggressive expansion appears to be built on a model of acquiring promising, underexplored assets at a low cost. The West Reveille property itself is a prime example. Black Mammoth acquired a 100% interest in the project from VR Resources Ltd. in a deal structured to minimize upfront financial risk. The agreement, signed in January 2025, required an initial cash payment of C$100,000, with a final C$25,000 due only before a drill program commences. The underlying owner retains a 3% net smelter royalty (NSR), aligning their long-term interests with Black Mammoth's exploration success. This capital-efficient approach allows the company to deploy its resources across a broad portfolio, increasing the statistical probability of making a significant discovery like the one at West Reveille.

A Complex Geological Puzzle with Carlin-Type Clues

Beyond the headline silver grades, the geological context of the West Reveille discovery is generating significant excitement. The mineralization is not limited to silver; it is part of a polymetallic system rich in base metals and important pathfinder elements like arsenic and antimony. This complexity points to a robust and long-lived hydrothermal system, which is often a prerequisite for large-scale mineral deposits.

Of particular interest is the discovery of a jasperoid zone in the southwestern part of the property. Jasperoid, a dense, silica-rich rock, is a key alteration feature associated with Carlin-type gold deposits, which are responsible for the majority of gold production in the United States. These massive deposits, for which Nevada is world-famous, contain microscopic or "invisible" gold and are among the most valuable mineral prizes on Earth. While the primary target at Reveille has been silver, the presence of jasperoid, combined with elevated arsenic and antimony, raises the tantalizing possibility that a Carlin-type system could exist on the property, potentially hidden beneath the shallow volcanic cover or in the adjacent pediment.

To test these geological concepts, Black Mammoth plans to conduct several induced polarization (IP) surveys. This geophysical technique can help detect sulfide minerals associated with silver, base metals, and Carlin-style gold mineralization that may be buried beneath the surface. The results of these surveys will be critical in defining drill targets to test the depth and scale of the mineralized system. All sampling and analysis for the reported results were conducted under a strict Quality Assurance/Quality Control program, with samples processed and analyzed by ALS Laboratory, an ISO-accredited facility, lending a high degree of confidence to the data.
