Mammoth Begins Field Activities At Its Tenoriba Gold-Silver Property, Mexico
Mammoth Resources Corp. (MTH) has commenced field activities at its 100% owned Tenoriba gold-silver project in Chihuahua, Mexico. The company is currently conducting a review of 55 prior diamond drill holes across three primary mineralized areas: Carneritos, Masuparia, and Moreno. These efforts include assessing access roads and drill pad locations to prepare for a permitted Phase 1, 60-hole maiden mineral resource diamond drill program, as referenced in an April 16, 2026 release.
A key objective of the current fieldwork is the collection of up to 200 kg of samples from the Carneritos area for advanced production-size leach tests. These tests aim to evaluate gold-silver recoveries and design initial small-scale leaching operations for oxidized gold-silver mineralized material. The samples are intended for advanced production-size, coarser fraction vat and column leach tests that simulate material coarseness and leach pad dynamics in a production-like leaching scenario.
The field activities involve reviewing drill core from the 55 prior diamond drill holes, which are distributed over an approximate 4 km strike length. The assessment of access roads covers the route from the camp and core storage to the three primary mineralized areas. The Carneritos area spans 1.5 km by 500 m, while the Masuparia and Moreno areas are also being evaluated for drill pad access and locations.
The Tenoriba project is characterized as a high sulfidation geological system. Mineralization includes gold, silver, and occasionally copper, identified through a combination of thousands of soil, surface chip, and channel samples alongside diamond drilling. Data used for the drill spacing study followed Quality Assurance and Quality Control (QA/QC) controls outlined on the company website. The referenced drill results press releases span from November 18, 2021, to December 15, 2022.
Richard Simpson, P.Geo., Vice-President Exploration, is the Qualified Person responsible for reviewing all technical data under National Instrument 43-101.
Thomas Atkins, President and CEO, stated: "We're excited to be on the ground at Tenoriba working to advance steps towards drilling what we believe could be a substantial maiden mineral resource at Tenoriba while at the same time also assessing a significantly advanced step to understanding gold-silver recoveries via a columns simulating material coarseness and leach pad dynamics in a production-like leaching scenario."
Mammoth recently entered into a strategic alliance with RM Mineria S de RL de CV of Mexico for additional advanced development and near-term production opportunities. Additionally, the project carries a 2% net smelter royalty purchasable anytime within two years from commencement of commercial production for US$1.5 million.
