Drill Results

BATTERY MINERAL RESOURCES DRILLS HIGH GRADE COPPER INTERCEPTS FROM THE

CINABRIO MINE AT ITS PUNITAQUI COPPER COMPLEX IN CHILE

Vancouver, British Columbia – (September 12, 2024) – Battery Mineral Resources Corp.

(TSXV: BMR) (OTCQB: BTRMF) ("Battery" or “BMR” or the "Company") is pleased to announce

encouraging drill core assay results from the new 2024 underground exploration and in -fill

drill program at the Punitaqui mine complex (“Punitaqui”) in Chile.

Highlights

• Assay results from drillholes (see Table 1) have returned with encouraging results as

follows:

o Drillhole CM-24-11: 18.3 meters (“m”) grading 2.6 percent (“%”) copper total (“CuT”)

and 11 grams per tonne (“g/t”) silver (“Ag”) including 14.9m at 3.1% CuT & 13g/t Ag

drilled as an infill hole delineated the extent of the mineralization intercepted

in historic drillholes CM-0-19-05 and CM-0-19-07

o CM-24-12: 6.4m grading 0.9% CuT and 5g/t Ag drilled as an extensional hole

defined the northern strike extent of the planned extraction area

o CM-24-13: 23.1m at 2.0% CuT & 14g/t Ag drilled as an infill hole confirmed

the extent of the mineralization intercepted in historic drillholes CM-0-19-05

and CM-0-19-07

o CM-24-14: 1.5m at 0.6% CuT & 1g/t Ag and 2.9m at 0.5% CuT & 14g/t Ag

drilled as an extensional hole confirmed the southern strike extent of the

planned extraction area

• The 2024 Cinabrio drill program is designed to confirm resources identified by previous

drilling programs and expand these resources along strike and at depth. All holes

reached target depth and have intersected the targeted shale-mudstone horizon that

hosts the copper mineralization.

• This phase of Cinabrio underground drilling targeted the Level 160 scheduled

production area where 4 drillholes totaling 173.6 meters of diamond core drilling were

completed (see Table 2 and Figure 1).

• The four holes were designed to confirm the modelled geology, mineralization and

probe the contact zone between the lower mineralized shale unit and the underlying

andesites within and adjacent to the planned extraction area (CM-24-11, CM-24-12.

CM-24-13 and CM-24-14).

• This drilling confirmed copper grades and better delineated the extent of the

mineralization in the lower shale unit and footwall andesite within and adjacent to the

planned extraction area.

• These drill results have been added to the three -dimensional geology and resource

models which BMR’s mining engineers will use to update the current mine designs and

optimize mining schedules.

• As of mid-August, the Cinabrio-San Andres underground drill program had resulted in

the completion of 31 drillholes / 1,300.4m including 18 holes / 770.2m at Cinabrio.

• Drilling is ongoing and a ssay results for the remaining 1 1 Cinabrio drillholes are

pending.

Battery Vice President of Exploration Peter Doyle stated, “These new, high-grade copper infill

drill results not only confirm the copper grades predicted by our current geological model but

also provide a more detailed understanding of the Level 160 target mineralization. The

ongoing underground drilling continues to demonstrate encouraging results that highlight the

potential of the Cinabrio mine.”

During the current operational ramp-up period, the underground drilling program is focused

on accessible targets within existing Inferred Resource to upgrade the resources to a higher

resource category as well as targeting areas adjacent to Inferred Resource to potentially add

new resources.

The 2024 drill plan allows for some flexibility in terms of timing and sequencing of target areas

which permits the drilling to be shifted between the Cinabrio mine and the adjacent San

Andres underground.

Cinabrio Mine

Sample assay results , reported herein, are from the second target tested as part of the

underground drilling at Cinabrio. These four BMR drillholes are infill holes designed to verify

and better delineate mineralization for the Level 160 target. Historic drillholes CM -0-19-05

and CM-0-19-07 drilled by Xiana Mining Inc. were both collared from a working above and to

the north of the Level 160 planned production area and drilled sub -parallel the stratigraphy.

Hole CM-0-19-05 intersected 1.2m at 0.5% CuT and 2.3g/t Ag from 30m and 4.4m at 1.9%

CuT and 4.9g/t A g. Drillhole CM -0-19-07 is interpreted to have drilled from the footwall

andesite into the lower part of the overlying sedimentary sequence and then back into the

footwall andesites. This hole intersected a mineralized zone in the shales in the lower part of

the sedimentary sequence that yielded an intercept of 3m at 6.6% CuT and 46.9g/t Ag.

All four of the BMR drillholes were drilled from the footwall andesite upward through the TSU

sedimentary unit and terminated at the old mine workings above the target area.

Drillhole CM-24-11 was designed to test the north -central part of the Level 160 planned

production area. The drillhole encountered weakly mineralized andesite near the contact of

the TSU sedimentary unit and then a well mineralized sequence of shales and sandstones

near the bottom of the hole which was stopped prior to encountering an old underground

working. Assay results reported included 18.3m grading 2.6% CuT and 11g/t Ag from 15.0m

including 14.9m at 3.1% CuT & 13g/t Ag from 18.6m. The drill hole confirmed the presence

of a significant zone of copper mineralization in the planned extraction area.

1406-6813-0063, v. 3

Drillhole CM-24-12 was planned to test the northern end of the planned extraction area. The

drillhole encountered footwall andesite from 0m to 30.9m which was weakly mineralized at

the top adjacent to the overlying TSU sedimentary sequence. F rom 30.9m to the bottom of

the hole (44.0m), this drillhole encountered variably mineralized sandstones and shales.

Assay intervals reported include 6.4m grading 0.9% Cu and 5g/t Ag from 34.9m. The drillhole

confirmed the northern limit of mineralization within the planned extraction area.

Drillhole CM-24-13 tested the south-central part of the planned extraction area. The drillhole

encountered footwall andesite from 0 m to 13.3m which is well mineralized . From 13.3m to

27.1m the section intersected consisted of a sequence of mixed shales and andesitic

volcanoclastics with variable mineralization. From 27.1 m to the bottom of the drill hole

(42.5m), the interval intersected well mineralized shales cut by an andesite dyke from 38.6m

to 42.4 m. Assay results include 23.1m at 2% CuT & 14g/t Ag from 12m . The drill hole

confirmed the presence of a significant high-grade zone of mineralization in the planned

extraction area.

Drillhole CM-24-14 was designed to test the southern extent of the planned extraction area.

This drillhole intersected footwall andesite from 0m to 30.3m followed by a section of

sandstones, shales and volcanoclastics from 30.3m to the bottom of the drillhole at 54.8m.

The hole yielded two weakly anomalous intercepts; 1.5m at 0.6% Cu & 1g/t Ag from 17m

and 2.9m at 0.5% CuT & 14g/t Ag from 44.5m. Drill hole CM-24-14 confirmed the southern

margin of mineralization in the planned extraction area.

Background – Cinabrio Deposit

The Cinabrio copper deposit mined by Glencore and Xiana Mining was the main ore source for

the Los Mantos processing plant for over 10 years . Cinabrio is the largest deposit mined to

date and is part of the Punitaqui project which is situated within a 25km long mineralized

district that is a classic IOCG and manto style copper belt that is comprised of manto and

structural controlled copper-silver veins.

On October 3, 2022, BMR published an NI 43-101 resource for Cinabrio at a 0.70 Cu% cut -

off.

• Indicated Sulphide Resource of 378,000 tonnes grading 1.55% CuT.

• Inferred Sulphide Resource of 90,000 tonnes at 0.98% CuT

In addition, Indicated resources for Cinabrio potentially recoverable pillars at a 0.70 Cu% cut-

off.

• Undiluted Indicated resources of 1,027,000 tonnes at grading 1.51% CuT

• Diluted Indicated resources of 1,312,000 tonnes at 1.27% CuT

1406-6813-0063, v. 3

Note: Scientific and technical information pertaining to the San Andres Resource was

extracted from the Company’s NI 43 -101 “Technical report on Punitaqui Copper Complex

Coquimbo, Chile” dated as of September 30,2022 with an effective date of August 16, 2022,

prepared by Garth Kirkham (Kirkham Geosystems Ltd.) an Independent Qualified Person in

accordance with NI 43-101.

The Cinabrio historic workings encompass about 700 vertical meters from the ridge-top oxide

workings to the lowest level of underground development. Within the underground mine level

development is spaced vertically at about a 30 meter interval.

The Cinabrio deposit is a tabular sedimentary horizon known as the “Targeted Stratigraphic

Unit” (“TSU”) within a volcanic sequence. This sedimentary horizon is variably mineralized and

has a variable width ranging from 5m - 30m. It consists of an interlayered volcano-sedimentary

sequence composed of dark colored laminated and unlaminated shales, volcanoclas tic

sandstone, conglomerates and breccias and tuff breccias. Most of the copper mineralization

is hosted in the shale units within the TSU package. The horizon dips 40 to 50 degrees to the

east.

Mineralization consists of veinlets and irregular disseminations in both the fine and coarse -

grained clastic rocks and locally within the volcanic rocks above and below the host unit. The

host horizon is also cut and offset by faults and dykes with a wide range of orientations.

Quality Control

Sample preparation, analysis and security procedures applied on the BMR exploration

projects are aligned with industry best practice. BMR has implemented protocols and

procedures to ensure high quality collection and management of samples resulting in reliable

exploration assay data. BMR has implemented formal analytical quality control monitoring for

all field sampling and drilling programs by inserting blanks and certified reference materials

into every sample sequence dispatched.

Sample preparation is performed BMR Los Mantos Preparation Lab. Samples are dried then

crushed to 70% < -2 millimeters and a riffle split of 250 grams is then pulverized to 85% of

the material achieving a size of <75 microns. Sample pulps & rejects were then delivered to

ALS Global - Geochemistry Analytical Lab in La Serana, Chile and sample analyses by ALS in

Lima, Peru. ALS analytical facilities are commercial laboratories and are independent from

BMR. All BMR samples are collected and packaged by BMR staff and delivered upon receipt

at the ALS Laboratory. Samples are logged in a sophisticated laboratory information

management system for sample tracking, scheduling, quality control, and electronic reporting.

These prepared samples are then shipped to the ALS Laboratory in No rth Vancouver for

analyses by the following methods:

• ME-MS61: A high precision, multi -acid digest including Hydrofluoric, Nitric, Perchloric

and Hydrochloric acids. Analysed by inductively coupled plasma (“ICP”) mass

spectrometry that produces results for 48 elements.

• ME-OG62: Aqua-Regia digest: Analysed by ICP-AES (Atomic Emission Spectrometry) or

sometimes called optical emission spectrometry (ICP-OES) for high levels of Co, Cu, Ni

and Ag.

1406-6813-0063, v. 3

Certified standards are inserted into sample batches by ALS. Blanks and duplicates are

inserted within each analytical run. The blank is inserted at the beginning, certified standards

are inserted at random intervals, and duplicates are analysed at the end of the batch.
