BLACK MAMMOTH METALS SAMPLES UP TO 717 G/T SILVER WITH 210 G/T AVERAGE AT AMADOR, NV

Black Mammoth Metals Corp. has released assay results from the recently completed rock chip sampling program conducted at its Amador silver property, situated in Lander county, Nevada, and located on the west side of the Toiyabe range, approximately 7.3 kilometres (km) (4.54 miles) north of the historic silver mining town of Austin.

The silver mineralization is hosted in a quartz vein shear, which appears to have been developed along a contact zone of Devonian sediments (Slaven chert) with plutonic intrusive. Previous operators have reported three-to-12-metre (m) drill intervals of significant silver mineralization, which have not been followed up to date. Black Mammoth's sampling program along the exposed quartz shear and from the nearby historic mining dumps consisted of 19 rock chip samples. A multielement assay package was then used with the objective to confirm historical sample results and to assess the silver potential of the property. As a result, the 19 rock samples had silver contents that averaged 210.3 grams per tonne (g/t) (6.76 ounces per ton (oz/t)), ranging from 1.7 g/t to 717 g/t (23.04 oz/t) (see the attached table), accompanied by strong trace element contents with As (arsenic) up to 3,350 parts per million (ppm), as well as Sb (antimony) (484 ppm) and Se (selenium) (94.1 ppm), with most exposures near the historical mining locations and along the range front.

Based on the results of the new rock samples, estimated thickness and strike length of the quartz vein shear, the company is encouraged to continue with further exploration. Since additional silver mineralization is suspected to continue downdip under cover to the east and can potentially be down dropped along the range front fault in the west, the company intends to conduct an induced polarization survey to determine the best locations for a first phase drilling program.

Acquisition terms (in U.S. dollars) and claims staking

Black Mammoth optioned five federal mining claims covering the key ground at Amador from a private vendor in March, 2024, by making an aggregate of $25,000 in cash payments (paid). These claims were considered a non-core asset and they are now 100 per cent owned by Black Mammoth. The company has since staked additional claims at Amador with its claims position now totalling approximately 172 hectares (425 acres). The Amador claims are administered by the Bureau of Land Management and the U.S. Forestry Service.

There are no royalties, work commitment amounts, finders' fees or share compensation in connection with the option.

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

• Big Bear copper property, Gila county, Arizona;
• Zulu gold property, Gila county, Arizona;
• Northern Star property, La Paz county, Arizona;
• Coal Canyon gold property, Pershing county, Nevada;
• Island Mountain gold district (including Coleman Canyon, St. Elmo and Diamond Jim (Ag (silver), Pb (lead), Zn (zinc), Sb)), Elko county, Nevada;
• Clover high-grade gold property, Elko county, Nevada;
• Leadore silver-lead-REE (rare earth element) property, Lemhi county, Idaho;

• Callaghan gold district (including North Callaghan, Charlie, Cottonwood and Rast properties), Lander county, Nevada.

Black Mammoth also has a 100-per-cent interest in the Blanco Creek gold property in the Elk Creek mining district, central Idaho, which hosts three historic underground mines along 3,550 metres (11,644 feet) of strike on the northeast-trending regional Blanco shear zone.

Quality assurance/quality control (QA/QC)

All sampling is conducted under the supervision of the company's project geologists and the samples are taken to the ALS Laboratory in Reno or Elko, Nev., for preparation and 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 (mm), then a 250-gram riffle split is then taken. This split is pulverized to a target of 85 per cent passing 75 microns and a 30-gram portion of this pulverized split is digested by four acids. A 41-element suite is run on the sample using the ALS ME-MS 41-multielement package. This method utilizes aqua regia digestion followed by low-detection ICP-MS (induced coupled plasma mass spectrometry) finish. Overlimit silver samples were processed using ALS's OG46 aqua regia digestion followed by ICP-AES (induced coupled plasma atomic emission spectroscopy) analysis. ALS laboratories have ISO 9001 and 17025 accreditations. Black Mammoth's QA/QC program includes regular insertion of CRM (certified reference material) standards, duplicates and blanks into the sample stream with a stringent review of all results. ALS also undertakes its own internal coarse and pulp duplicate analysis to ensure proper sample preparation and equipment calibration.
