Battery Mineral Resources Announces Intercept of 34 Meters of 1.35% Copper from the Cinabrio Norte Target at Its Punitaqui Copper MINE IN Chile

Drill Results

BATTERY MINERAL RESOURCES ANNOUNCES INTERCEPT OF 34 METERS OF

1.35% COPPER FROM THE CINABRIO NORTE TARGET AT ITS PUNITAQUI

COPPER MINE IN CHILE

Vancouver, British Columbia – (April 26, 2022) – Battery Mineral Resources Corp.

(TSXV: BMR) (OTCQB: BTRMF) ("Battery" or “BMR” or the "Company") is extremely

pleased to announce encouraging drill core assay results from the ongoing 2021 –

2022 exploration and infill drill program focused on extensions of the Cinabrio

orebody, the Dalmacia target and San Andres target within the Punitaqui mine

complex (“Punitaqui”) in Chile. These drilling results continue to highlight the strong

copper grades and the growing vertical extent of the Cinabrio Norte target.

Punitaqui is slated for resumption of copper concentrate production in Q4-2022. The

Cinabrio Norte target represents a potential northern extension of the main Cinabrio

mine orebody, which historically was the primary source of ore feed to the Punitaqui

copper ore concentration plant for eight-plus years (see Figure 1).

Highlights

• New assay results for Cinabrio Norte include the following (see Table 1):

o CNN-22-08: 33.4 meters (“ m”) at 1.08% C opper (“C u”) including

18.9m at 1.23% Cu

o CNN-22-21: 34.1m at 1.35% Cu including 19.5m at 1.60% Cu

o CNN-22-16: 22.5m at 1.15% Cu

o CNN-22-13: 4.9m at 1.25% Cu

o CNN-22-10: 3.3m at 0.82% Cu

• At Cinabrio Norte, 41 holes have been completed for 9,472 meters (“m”) and

drilling is ongoing with two diamond drills.

• Significant visual copper mineralization has been recorded in 30 of the 41 holes.

• To date, the drilling has outlined a significant zone of high-grade mineralization in

the northern portion of the target area which remains open at depth.

• The initial phase 1 program of step -out holes has been expanded from 24 holes

(3,600m) to 45 holes, totaling 11,000m which will test 400m of strike length to a

depth of 330m.

Battery CEO Martin Kostuik states; “We are continuing to produce encouraging results

from the identified targets at our former producing Punitaqui copper mine in Chile.

These recent drillhole results at the Cinabrio Norte target have produced very positive

copper grades and further highlighted the down-dip extent and thickness. Cinabrio

Norte is about 100 meters north of the original Cinabrio deposit which was the

primary source of copper ore feed to the Punitaqui mill for eight-plus years. This new

target has the potential to provide the Company with an additional source of copper

mineralization as ore feed for the Punitaqui processing plant.”

Furthermore, CEO Kostuik remarks: “The development of Punitaqui towards a restart

is progressing well on all fronts , including drilling, engineering and permit

modifications. We look forward to the potential of these latest assay results for the

Cinabrio Norte Target contributing to the forthcoming restart plan and cashflow at

Punitaqui later this year”.

Cinabrio Norte Drill Program

The Cinabrio Norte phase 1 drill testing will continue to follow-up on a limited number

of historic drillholes that targeted the northern extension of the Cinabrio orebody.

The historic exploration drilling confirmed that the favorable targeted stratigraphic

unit (“TSU”) that hosts the copper mineralization within the Cinabrio orebody extends

to the north. The TSU has been mapped along a north -south strike from the mine.

Importantly, the Cinabrio Norte target is only 110m north of the Cinabrio

underground workings on level 200m. Historic hole CNS -20-01, drilled in 2020

by the prior operators, was drilled completely within the TSU resulting in multiple

mineralized intercepts an d, most notably, confirmed the presence of TSU for over

200m of strike length with significant copper sulphide mineralization (CNS-20-01:

48m at 0.64% Cu, 3m at 0.47% Cu and 6m at 0.45% Cu).

The current drilling was planned as a series of step-out holes to test the TSU 400m

along strike (north -south) to a depth below surface (“down -dip”) of 330m. The

current BMR drilling has outlined a significant zone of high -grade mineralization in

the northern portion of the target zone which remains open at depth. This initial

phase 1 program of step-out holes has been expanded from 24 holes (3,600m) to 45

holes, totaling 11,000m. Significant visual copper mineralization has been recorded

in 30 of the 41 holes completed to date. The remaining planned holes will test “drilling

gaps between the existing underground workings and the northern zone as well as

further test the mineralization at depth.

Complete assay results were recently received for nine holes (see Figure 1 and Table

1).

o CNN-22-06: 15m at 1.24% Cu

o CNN-22-07: 41.5m at 1.36% Cu

o CNN-22-09: 25m at 0.65% Cu.

Please refer to news releases dated March 15, 2022 and April 13, 2022 for previous

drill assays.

Drillhole CNN-22-08 was drilled in the northern end of the target and was planned

as a 50m step -out down-dip on the targeted stratigraphic unit (“TSU”) from the

earlier intercept in hole CNN -22-01 of 26m at 1.28% Cu. This hole successfully

intercepted 53m of the TSU within which a 33.4m intercept grading 1.08% Cu was

returned from 194.7m downhole including 18.9m at 1.23% Cu from 195.2m. The

intercept confirms both the vertical continuation and grade of the copper

mineralization.

Drillhole CNN-22-10 was drilled in the central part of the target to test TSU down-

dip of the broad, well mineralized intercept in CNN-22-07 of 41m grading 1.36%

Cu. A 17m TSU section was drilled from 133.3m with spotty chalcopyrite in the upper

part of the unit that yielded 3.3m at 0.82% Cu. This hole confirms that in the central

part of the zone the TSU appears to be thinner at these depths. Whether this change

in the TSU is attributable to a structural or stratigraphic control is yet to be

determined.

Drillhole CNN-22-11 was planned as a down-dip test of the TSU in the central part

of the target area. The hole was a down -dip step-out of the previous hole CNN -22-

10 that intercepted 3.3m at 0.82% Cu. The new hole cut a 23m section of the TSU

with variable pyrite, minor copper mineralization and a best copper result of 3m at

0.31% Cu from 256m. The results further indicate a thinning of the TSU down -dip

in the central part of the Cinabrio Norte target. Future drilling will test thickness at

greater depths.

Drillhole CNN-22-13 was collared in the central part of Cinabrio Norte and targeted

the TSU down-dip of holes CNN-21-05 (2.5m at 0.46% Cu) and CNN-22-02 (13m

at 1.36m). CNN-22-13 successfully intercepted 24m of TSU that produced an assay

interval of 4.9m grading 1.25% Cu from 246.1m and indicates a continuation of

mineralization down-dip in this area.

Drillhole CNN-22-16 was collared in the northern part of the target area and was

designed as a down-dip step-out of the TSU from the CNN-21-11 intercept of 7m at

1.21% Cu. The new hole intercepted a 100m section of the TSU that yielded a

22.5m intercept at 1.15% Cu from 162.5m thus confirming the down -dip

continuation of the mineralization. This new intercept further supports this

interpreted mineralized copper zone in the northern part of Cinabrio Norte.

Drillhole CNN-22-17 was drilled in the central Cinabrio Norte area as a down-dip

step-out of hole CNN-22-09 that cut 25m at 0.65% Cu hosted within a 40m section

of the TSU. The new hole intercepted a narrower TSU section of 15m that produced

an assay interval of 9m grading 0.37% Cu from 174m.

Drillhole CNN-22-18 was drilled in the southern part of Cinabrio Norte area and

targeted a down-dip step-out of the CNN-21-02 copper intercept of 13m at 1.35%

Cu hosted within a 32m section of the TSU. This hole cut a 30m section of TSU with

only minor copper sulphide mineral ization that resulted in a best assay of 2.5m

grading 0.55% Cu from 239m.

Drillhole CNN-22-20 was collared in the central part of Cinabrio Norte and targeted

the TSU down-dip of CNN-22-13 that intercepted a 24m section of TSU and an assay

of 4.9m at 1.25% Cu. CNN-22-20 intercepted 17m of TSU with only minor copper

sulphides that produced an assay interval of 4.6m grading 0.18% Cu from 329.8m.

Drillhole CNN-22-21 was a follow-up hole designed to test the TSU and copper

sulphides north of previously reported CNN -21-06 that resulted in an 83m zone of

TSU that returned 53m at 0.91% Cu including a higher -grade zone of 20.8m

grading 1.14% Cu. The new hole successfully intersected 90m of TSU that resulted

in assays of 34.1m at 1.35% Cu from 104m including 19.5m grading 1.60% Cu

from 118.5m. This result further supports the presence of a significant zone of copper

mineralization in the northern area of Cinabrio Norte.

projects is aligned with industry best practices. 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 by ALS Global - Geochemistry Analytical Lab in La

Serena, 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 info rmation

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

reporting. 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. These prepared samples are then shipped to the ALS Laboratory in Lima

Peru for analyses by the following methods:

• ME-ICP61: A high precision, multi -acid digest including Hydrofluoric, Nitric,

Perchloric and Hydrochloric acids. Analysed by inductive ly 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 elevated levels of Co, Cu, Ni and Ag.

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.
