Black Mammoth Metals Finds Large Chargeability Anomaly Underlying the Historic Workings and Stakes Claims at Amador Silver Property, NV

The most recent news release, dated December 8, 2025, states that Black Mammoth Metals Corporation has received results from an induced polarization (IP) geophysical survey at its 100% owned Amador silver property in Lander County, Nevada. The survey successfully delineated a large high-chargeability anomaly, extending at least 1.22 kilometers along the range-front and underlying historic mine workings. This anomaly aligns with areas that have previously shown high-grade silver in historic and recent sampling. Concurrently, the company has staked 55 new unpatented lode claims, expanding the Amador property to approximately 631 hectares. Black Mammoth plans to permit five drill sites to test this newly identified anomaly.

This news is a positive, but routine, development for Black Mammoth Metals. It represents a successful step in the exploration process at the Amador silver property, confirming the geological model and advancing the project to the drilling phase. The identification of a significant chargeability anomaly, which correlates with known high-grade surface silver mineralization (as reported in the July 22, 2025 news, where rock chip samples averaged 210.3 g/t Ag and went up to 717 g/t Ag), is encouraging. The expanded land package through additional claim staking further enhances the project's potential.

However, it is important to note that a chargeability anomaly is a geophysical target, an indirect indicator of potential mineralization, not direct evidence of economic ore. While it de-risks the upcoming drill program by providing well-defined targets, it does not provide new resource estimates or high-grade drill intercepts. This news is in line with the company's previously stated plans to conduct an IP survey and subsequent drilling at Amador. Therefore, it confirms expectations and execution on the exploration front, rather than representing a material, game-changing discovery.

Financially, the company's cash position as of September 30, 2025, was $2.66 million. The exploration burn rate for the first nine months of 2025 was substantial, approximately $3.6 million in investing activities, in addition to operating expenses. While the company has significant potential funding from in-the-money warrants and options (totaling potentially ~$3.8 million if all were exercised at the current share price), continued aggressive exploration across its multiple properties will place ongoing demands on its treasury. The cost of permitting and conducting a five-drill site program at Amador will contribute to this burn rate.

Black Mammoth Metals Corporation is a Canadian junior exploration company focused on acquiring and developing precious and base metal properties in the Western United States, primarily Nevada and Arizona. The company has aggressively expanded its property portfolio throughout 2025, accumulating a diverse range of gold, silver, copper, and rare earth elements (REE) projects.

While no single project is explicitly termed the "flagship" by the company, the Amador silver property in Nevada is currently one of its most advanced and promising exploration projects. The company recently reported high-grade rock chip samples (up to 717 g/t Ag) and has now delineated a large, drill-ready chargeability anomaly extending over 1.22 km. This project, which is 100% owned and royalty-free, is poised for initial drill testing.

Other significant projects include: * Ramsey Silver Property, AZ: Acquired for a low cash cost and royalty-free, with historical drilling reporting wide zones of high-grade silver (e.g., 44.4m at 62.5 g/t Ag). * America Mine Gold Property, CA: Purchased outright for $500,000 USD, 100% owned, royalty-free, and presents an open-pit heap leach opportunity. * Leadore Silver-Lead-REE Property, ID: Exhibited high-grade REE mineralization (up to 7.6% TREO with a 26% NdPr ratio) and a high-priority IP chargeability anomaly. * St. Elmo Gold Property, NV: Hosts a large, high-grade epithermal vein system with bonanza-grade historical drill intercepts and a bulk sample. * Coleman Canyon Gold Property, NV: Acquired with existing (though outdated) NI 43-101 resources and Carlin-type gold potential. * Callaghan Gold Property, NV (Cottonwood, Rast): Early-stage drill results confirmed gold mineralization and pathfinder elements, suggesting a large intrusive-related gold system.
