BLACK MAMMOTH METALS SAMPLES UP TO 2,610 G/T SILVER AT WEST REVEILLE, NV

Black Mammoth Metals Corp. has released assay results from the recently completed rock chip sampling program conducted at its West Reveille silver property situated in the Reveille mining district, Nye county, Nevada, and is located on the western Reveille Mountains. Reveille covers a historic primary silver camp that dates back to the 1870s with only light modern-day exploration or drilling. The Reveille property consists of 32 unpatented lode claims on lands administered by the Bureau of Land Management (BLM) covering approximately 267 hectares (661 acres).

Exploration work has revealed and confirmed high-grade silver occurrences, accompanied by high lead, zinc and copper concentrations, as well as elevated pathfinder elements (arsenic up to 1,360 parts per million and antimony up to 3,110 ppm) and Table 1.

The strike length of the exposed alteration zone is approximately two kilometres. The silver and base metal mineralization appears to be associated with and occurs along the contact zones between younger felsic volcanic rocks (extrusive domes) and older country rock Paleozoic sediments. These contact zones are strongly silicified and exhibit vein textures characterized by quartz veins. A jasperoid zone discovered in the southwestern part of the property is of special interest due to its potential for Carlin-type deposits in the pediment area.

The company sees exploration potential along the mineralized volcanic-Paleozoic contact zones, particularly beneath the pyroclastic cover and in the pediment, and plans several induced polarization (IP) surveys to test the target concepts.

Acquisition terms (in Canadian dollars)

Under the terms of the acquisition agreement with VR Resources Ltd. signed in January, 2025, Antelope Creek paid a cash payment of $100,000 at signing and will own a 100-per-cent interest in the West Reveille property and related exploration data package by making a final cash payment of $25,000 due prior to commencement of a drill program.

The underlying owner of the property retains a 3-per-cent net smelter royalty (NSR) on all claims and within the area of interest. There are no work commitment amounts, finders' fees or share compensation in connection with the agreement.

The company continues to acquire non-core exploration interests in the Western United States, by purchase or staking.

Quality assurance/quality control

All sampling was conducted under the supervision of the company's project geologists. The samples were taken to the ALS Laboratory (ALS) in Elko, Nev., for preparation; then transferred by ALS to their laboratory to Reno, Nev., for analysis.

The ALS PREP-31 package was utilized for sample preparation. In this package, each sample is crushed to better than 70 per cent, passing two millimetres, then a 250-gram riffle split is then taken. This split is pulverized to a target of 85 per cent passing 75 micrometres; and a 30-gram portion of this pulverized split is digested by aqua regia. A 41-element suite was run on the samples using the ALS ME-MS 41 multielement package. This method utilizes the aqua regia digestion followed by low detection ICP-MS (induced coupled plasma) finish. Overlimit elements from this analysis were analyzed by aqua regia digestion followed by ME-OG46 ICP-AES (induced coupled plasma). Elements in this group included Ag (silver), Cu (copper), Pb (lead) and Zn (zinc).

Gold was analyzed using an aqua regia digestion, followed by the Au-ICP 21 method, which is a 30 g charge fire assay, with an ICP-AES (induced coupled plasma) finish. Gold was also analyzed by Au-GRA21 which is an aqua regia digestion followed by a 30-gram charge fire assay, with a gravimetric finish. Silver was analyzed by aqua regia digestion, followed by Ag-GRA21 which is 30 g charge fire assay with a gravimetric finish.

ALS Laboratories have ISO 9001 and 17025 accreditations. Black Mammoth Metals' QA/QC (quality assurance/quality control) program includes regular insertion of CRM standards, duplicates and blanks into the sample stream with a stringent review of all results. ALS also undertakes their own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration.
