BLACK MAMMOTH METALS ACQUIRES RAMSEY SILVER PROPERTY, AZ

Black Mammoth Metals Corp. has completed the acquisition of the Ramsey silver property. The property consists of two patented claims and 12 federal lode claims on BLM (Bureau of Land Management) administered lands totalling approximately 100 hectares (247 acres) located in La Paz county, Arizona. The property has excellent access and is situated in the foothills of the New Water Mountains, six kilometres (km) southwest of the town of Brenda, in the Plomosa mining district within the Sonora Desert portion of the basin and range physiographic province. The company now owns the Ramsey silver property 100 per cent with no royalties and an extensive data package.

Adjacent to the historic Ramsey mine, significant silver mineralization has been intersected in 2016-2018 drilling, as well as in historical drilling in the 1960s with strong surface geochemical values. Exploration work also includes surface mapping and geophysical surveying in recent years, producing drill targets. The silver mineralization intersected in the recent drilling is close to surface rendering it possibly amenable to open-pit development.

Best drill intercept:

• 44.4 metres (m) containing 62.5 grams per tonne (g/t) silver at 79.4 to 123.5 m downhole depth with approximate true width of 35 m. This interval is contained within a wider zone of silver mineralization between 64 and 152.4 m: 88.4 m with approximate true width of 70 m averaging 42.6 g/t silver. R1706 was drilled at minus 75 degrees bearing 60 degrees azimuth on the patented ground. The drilling may have intersected the periphery of a silver-bearing hydrothermal system (reverse circulation drill hole R1706 in 2017).

Black Mammoth looks forward to commencing a complex review of the Ramsey data package and an on-site evaluation of this high prospective property.

Acquisition terms (in U.S. dollars)

The patented claims were purchased from a private vendor for $30,000 and the BLM claims were purchased from a separate private vendor in June, 2025, for $12,000. There are no royalties, finders' fees or share compensation in connection with the Ramsey property acquisition.

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

QA/QC (quality assurance/quality control) and analytical procedures (drill hole R1706, Arizona Silver Exploration, 2017)

All drill cuttings were transported under strict chain of custody by ALS Minerals personnel to the ALS Minerals laboratory in Tucson, Ariz., where samples were dried and crushed to 70 per cent passing two millimetres (mm), a 250-gram (g) split is taken and pulverized to 85 per cent passing 75 microns, subject to a four-acid digestion, and then analyzed by ICP-MS (inductively coupled plasma mass spectrometry) for a 48-element package, including silver, lead and zinc. Samples over 100 parts per million (ppm) silver and over 10,000 ppm lead or zinc are reanalyzed using ICP for higher concentration levels. Selected intervals with high silver values are resubmitted for one-assay-ton fire assays for gold.
