Battery Mineral Resources Announces Intercept of 48 Meters of 1.31% Cu from the Cinabrio Norte Target at Its Punitaqui Copper MINE IN Chile

Drill Results

BATTERY MINERAL RESOURCES ANNOUNCES INTERCEPT OF 48 METERS OF

1.31% Cu FROM THE CINABRIO NORTE TARGET AT ITS PUNITAQUI

COPPER MINE IN CHILE

Vancouver, British Columbia – (June 27, 2022) – 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 recently completed Phase

1 2021–2022 exploration and infill diamond drill program focused on extensions of

the Cinabrio orebody , the Dalmacia target and the San Andres target within the

Punitaqui mine complex (“Punitaqui”) in Chile . The Punitaqui mine is slated for

resumption of mine operations in the second half of 2022.

The Cinabrio Norte target represents a potential norther n extension of the main

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

Punitaqui copper ore concentration plant for eight -plus years. These drill results

continue to highlight the presence of strong copper mineralization and the significant

vertical extent of the Cinabrio Norte target (see Figure 1).

Highlights

• At Cinabrio Norte the Phase 1 drill program consisted of 53 diamond drill holes

with a total of 13,731 meters (“m”).

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

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

• The initial Phase 1 program of step-out holes was expanded from the planned 24

holes (for approximately 3,600m) to 53 holes to further test the down-dip extent

of the copper (“Cu”) mineralization ultimately reaching a depth of 350m below

surface.

• The results of the North Zone at Cinabrio Norte include:

o CNN-22-30: 164m at 0.80% Cu including 48.0m at 1.31% Cu, 12.5m

at 0.91% Cu and 19.4m at 1.15% Cu

o CNN-22-40: 14m at 1.62% Cu

o CNN-22-41: 9m at 1.15% Cu

o CNN-22-19: 4.1m at 1.38% Cu

o CNN-22-19A: 16.6m at 0.85% Cu including 5.4m at 1.16% Cu

• Results from the South and Central Zones at Cinabrio Norte include:

o CNN-22-33: 14.9m at 1.79% Cu including 2.8m at 3.66% Cu

o CNN-22-25: 4m at 0.48% Cu including 18.9m at 1.23% Cu

o CNN-22-26: 4m at 1.18% Cu

o CNN-22-29: 14m at 0.76% Cu including 5m at 1.01% Cu

o CNN-22-32: 9m at 0.43% Cu

o CNN-22-38: 4.3m at 1.09% Cu

Battery CEO Martin Kostuik states; “We are very pleased to report these encouraging

results from Cinabrio Norte at our former producing Punitaqui copper mine in Region

IV of Chile. Cinabrio Norte began as a collection of a few interesting holes to the

immediate north of the original Cinabrio mine. Cinabrio, until May of 2020, produced

feed to the Punitaqui copper concent rator for nine -plus years. Today’s reported

drillhole results conclude the initial drill program at Cinabrio Norte and, together with

the previously reported results, clearly demonstrate a new extension of Cinabrio to

the north. Th ese new targets have the potential to provide the Company with an

additional source of copper mineralization as feed for the Punitaqui processing plant.”

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

of mine operations, followed by a re -start of the copper concentrating plant, is

progressing well on all fronts . Efforts are multi -faceted and include drilling,

engineering, metallurgical test work and permit modifications. We look forward to

the potential of these latest assay results for th e Cinabrio Norte target contributing

significantly to the forthcoming resource report and subsequent restart plan for the

mine”.

Cinabrio Norte Drill Program

The Cinabrio Norte Phase 1 drilling was designed 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 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 Cinabrio mine. Of note, 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 and, 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 20221-2022 Phase 1 drilling at Cinabrio Norte consisted of a series of step-out

holes to test the TSU along a 400m strike length (north-south) to a depth below

surface, or down-dip, of 350m. The current BMR drilling has outlined a significant

zone of high-grade mineralization in the northern portion of the target zone which

remains open down-dip.

Complete assay results were recently received for all 18 remaining drill holes from

the Phase 1 campaign at Cinabrio Norte (see Figure 1 and Table 1). As of this press

release, all assays from the entire Phase 1 program (Cinabrio Norte, San Andres and

Dalmacia) have now been reported.

Quality Control

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

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 ex ploration 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 deli vered 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. 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 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 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 r un. The blank is inserted at the beginning,

certified standards are inserted at random intervals, and duplicates are analysed at

the end of the batch.
