/CNW/ -
Black Mammoth Metals Corporation
(TSXV: BMM)
(OTC: LQRCF)
("Black Mammoth" or the "Company")
is pleased to announce the discovery of
high-grade rare earth element (REE) mineralization at its Leadore Property ("Leadore") in
Lemhi
County, Idaho
. Recent rock chip sampling (see Company's NR 24-18) has returned grades of up to
7.6% total rare earth oxides (TREO) with a highly favorable NdPr (neodymium-praseodymium) ratio
averaging 26% in five samples grading over 1% TREO.
This newly recognized REE
mineralization occurs in a placer or laterite horizon sitting atop the known fault-hosted lead
and silver mineralization.
Highlights:
All samples taken in the laterite horizon are REE enriched with
five samples exceed 1%
TREO, with the highest sample returning 7.6% TREO (see Table 1).
NdPr ratios are high, averaging 26%
; neodymium and praseodymium are economically
important critical metals used in electric vehicle motors and turbines.
This new REE mineralization is on trend with the Idaho REE-Belt, a series of lode/vein and
placer REE deposits trending northwest through nearby
Salmon, ID.
Low phosphorus, thorium and uranium content
suggests REEs are hosted in oxide minerals
rather than phosphates, increasing potential processability and with minimal radioactivity.

Geological Significance:
The newly identified REE mineralization at
Leadore
is
oxide-dominant
, with mineralization likely
hosted in bastnäsite and associated Fe-Mn oxides, rather than traditional phosphate minerals with
elevated Th-U such as monazite. The mineralization occurs in a lateritic environment as shown in
Photo 1, indicating supergene enrichment through weathering processes or transport from a nearby
REE-rich intrusion or vein. This setting is similar to economically viable REE deposits worldwide,
including
China's
ion-adsorption clay deposits, which are known for their ease of processing and
similarly elevated NdPr and TREO.

Next Steps
:
Mineralogical Studies:
Conduct mineralogical test work, such as Tescan Integrated Mineral
Analyzer (TIMA-X), to identify REE mineral species and to assess potential for processing.
Further Sampling:
Sample laterite outcrops along trend to assess scale and continuity of the
REE mineralization.
Refining the Geologic Model
CEO Commentary:
Dustin Henderson
, CEO of Black Mammoth, states:
"We are extremely encouraged by these
results, which confirm high-grade rare earth mineralization at
Leadore
with an economically
attractive NdPr ratio. With permanent magnet rare earths being sought after elements, this
discovery may position Black Mammoth to play a significant role in the North American REE
supply chain. Our next steps at
Leadore
will help our understanding of processing potential."
Sampling Program:
The sampling program consisted of 38 rock chip samples collected and delivered to ALS Global in
Elko, NV
during
October 2024
and analyzed using the following prep and analytical procedures as
described in the ALS Global 2024 price list: Prep 31Y, Au-ICP22 (Using a 50gram charge, FA ICP-
AES finish), ME MS41 (Ultra Trace ICP-MS). Over limit samples for Ag also were analyzed using
Ag-OG46 and Ag-GRA21 (30gram charge FA-Gravimetric finish). Over limit samples for Pb were
analyzed using Pb-0G46.
About the Leadore Property:
Located in
Lemhi County, Idaho
,
Leadore
hosts historical silver-lead mineralization and is now
emerging as a promising REE property consisting of
74 Federal lode mining claims
covering
approximately
1,528 acres (618 hectares)
. The Property has road access year-round, with
infrastructure advantages that support cost-effective exploration and potentially development.
The Company also continues to acquire non-core exploration interests in the western US, by
purchase and by staking.
About Black Mammoth Metals Corporation:
In the past 12 months, Black Mammoth Metals has acquired a 100% interest in:
Clover High-Grade Gold property,
Elko County, NV
,
Coleman Canyon property,
Elko County, NV
,
Leadore Silver-Lead property
,
Lemhi County, ID
,
East Reveille Gold property
,
Nye County, NV
,
America Mine Gold
property
,
San Bernardino, CA
,
Quito Gold property
,
Lander County, NV
South Ravenswood
District
,
Lander County NV
,
Callaghan Gold District
,
Lander County NV.
Drilling on-going.
At the Company's 100% owned, 1,213 hectare (2,997 acre)
Happy Cat Gold property
,
Lander
County, NV
, an approximate 4 square kilometre area is identified as being hydrothermally altered.
Structural modelling suggests the density of the alteration and its' density contrast relative to the
host rock is typical to that of alteration zones present at other
Carlin
-type deposits in northern
Nevada
. The alteration encompasses an area where northerly trending high-angle faults intersect
indicated NW-trending re-activated faults that are known to be of age and orientation as ore-
controlling faults occurring at other
Carlin
-type deposits. The Company drilled approximately
1600m
in
January 2025
to further understand the structure and stratigraphy. Results are pending.
Black Mammoth also has a 100% interest in the
Blanco Creek Gold property
in the Elk Creek
Mining District, central
Idaho
, which hosts three historic underground mines along 3,550 meters
(11,644 feet) of strike on the north-east trending regional
Blanco Shear Zone
. Exploration by two
previous operators identified a geological target for the Blanco Creek property in the order of 1.70
to 2.48 million tons, grading 0.20 to 0.33 oz/ton Au (1.54 to 2.24 million tonnes, grading 6.85 to
11.31 g/tonne Au); see the Company's press release dated
February 14, 2017
.
Black Mammoth cautions investors to note the potential quantity and grade of the geological target
are conceptual in nature. A qualified person has not completed sufficient work to classify the
geological target as mineral resources as defined by NI 43-101, and it is uncertain if future
exploration will result in the target being delineated as mineral resources.
