Black Mammoth Metals Reports Rock Chip

Sampling Results at Coal Canyon, NV

BMM: TSX-V

VANCOUVER, BC

May 28, 2025

/CNW/ -

Black Mammoth Metals Corporation

(TSXV: BMM)

(OTC: LQRCF)

("Black Mammoth" or the "Company")

is pleased to report assay results from the

recently completed rock chip sampling program conducted at its Coal Canyon Gold Project ("Coal

Canyon" or the "Property") situated in

Pershing County, Nevada

and is located on the west side of

the Humboldt Range, approximately 14 km southwest of the

Rochester

gold and silver deposit and 2

km south of the Willard Mine (see Figure 1).

The Company began evaluating its Coal Canyon property after collecting 20 rock chip samples from

roadcuts and other outcrops. The samples were submitted to ALS Chemex for Au-ICP21 and the

ME-MS41 multi-element package to confirm historical sample results and assess the remaining gold

potential on the Property.

As a result, most rock samples had gold contents ranging from

several tenths of a g/t up to 2.28 g/t

,

accompanied by strong trace element contents with As

up to 7120 ppm, as well as Sb (100.5 ppm) and Se (44.7 ppm)

(see Figures 2, 3 & 4). The

altered and mineralized material appears to be exposed in a window of silicified carbonates of the

Lower Plate and in adjacent intrusive (sills), with strong enrichment of iron oxides along the

fractures; most of the area is covered by gravel or unmineralized shale of the Upper Plate (see

Figure 5).

Based on the results of the new rock samples and the extensive alteration and oxidation along the

roadcuts, the Company is encouraged to initiate further exploration steps. Since additional gold

mineralization potential is suspected under cover, the Company intends to conduct an induced

polarization survey and detailed mapping.

Previously Reported Highlights

(Company's NR dated

April 15, 2025

):

Multiple types of mineralization.

Road cut sampling up to:

46m

@ 0.76 g/t Au (oxide).

An extensive soils grid shows strong silver and molybdenum values surrounding the gold

mineralized zone.

Existing drill permit with Bureau of Land Management needs change of operator.

Drill roads and pads constructed.

Quality Assurance/Quality Control:

All sampling is conducted under the supervision of the Company's project geologists and the

samples are taken to the ALS Laboratory (ALS) in

Reno

or

Elko, Nevada

for preparation and

analysis.

The ALS PREP-31 package is utilized for sample preparation. In this package, each sample is

crushed to better than 70%, passing 2mm, then a 250-gram riffle split is then taken. This split is

pulverized to a target of 85% passing 75microns; and a 30-gram portion of this pulverized split is

digested by Four Acids and analyzed for gold by the Au-ICP 21 method, which is a Fire Assay, with

an ICP-AES (Induced Coupled Plasma) finish. A 41-element suite is also 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) finish. ALS Laboratories have ISO 9001 and 17025

accreditations. Black Mammoth Metals Corp's QA/QC 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.
