Battery Mineral Resources Corp. Announces Facility Increase and Maturity

Extension of Bridge Loan, Exploration Update on Cinabrio Concessions, and

Publication of Inaugural ESG Report

Vancouver, British Columbia – (June 7, 2023) – Battery Mineral Resources Corp.

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

announces that it has entered into an amendment to its existing bridge loan facility

provided by Weston Energy LLC (the “ Lender”). The amendment increases the

facility size from USD$4,000,000 to USD$5,300,000 and extends the maturity date

to September 15, 2023. All other terms remain unchanged.

Martin Kostuik, BMR CEO and Director stated, “Battery is very pleased that our largest

shareholder continues to demonstrate their strong support of the company and

provide an additional USD$1,300,000 in funding on favorable terms . This funding

will assist in the development of the Punitaqui project until project financing for the

restart of production at Punitaqui is procured . The Company intends to use the

proceeds of the expanded loan to continue advancing Punitaqui towards restarting

sustainable copper concentrate production, and for additional working capital . We

look forward to announcing the f unding of the restart of the Punitaqui mine in the

near term.”

The Lender has control or direction over securities of the Company carrying more

than 10% of the voting ri ghts attached to all of the Company’s outstanding voting

securities. Accordingly, the Loan is considered a related party transaction under the

policies of the TSX Venture Exchange (the “ TSXV”). The Company is exempt from

the formal valuation requirement under Multilateral Instrument 61-101 Protection of

Minority Security Holders in Special Transactions (“MI 61-101”) as its securities are

listed for trading on the TSXV. The Company is also exempt from the minority

approval requirement under MI 61-101 as the Loan has been provided on reasonable

commercial terms that are not less advantageous to the Company than if it were

obtained from an arm’s length party. Further, the Loan is not convertible into or

repayable in securities of the Company.

Exploration Update – Cinabrio Concessions Ground Magnetics Survey

BMR recently completed a detailed ground magnetics survey of 620 line-km over the

Cinabrio concessions at the Punitaqui Mine Complex. These concessions host the

historic Cinabrio mine, the San Andres resource, and the Cinabrio Norte resource.

The principal goal of the survey was to characterize the magnetic signature of the

formerly producing Cinabrio mine, and the San Andres and Cinabrio Norte resources.

intends to use this magnetic signature information to explore the greater property

area to attempt to discover potential new mineralization.

The magnetic survey clearly delineated a magnetic signature for the known deposits

and significantly enhanced the understanding of several prospective targets onBMR

claims.

Details of Program

Argali Geofisica Chile E.I.R.L completed the field work in two phases, the eastern grid in June

2022 (301.7 line-km) followed by the adjacent western block in February 2023 (317.8 line -km).

Both survey grids consisted of east-west lines and some north-south tie-lines with a

spacing of 50m (see Figure 1: RTP Magnetics plot with known mineral deposits and

exploration targets). Magnetic data was acquired as a continuous profile once every

second that yielded a station spacing of approximately 0.5m to 1.5m. Survey control

was maintained with an internal high-quality GPS system. Complete UTM coordinates

and elevation data were simultaneously acquired with each magnetic reading. A GEM-

19 magnetometer was used as a base station and a second unit as the mobile survey

unit. During data processing all of the magnetic responses identified during the field

survey attributable to physical features such as mine infrastructure, power lines,

fences, houses and pipelines were deleted. The following magnetic products were

generated from the data:

- Total Field Map (TMI)

- Pole-Reduced (RTP) Map (Upward continued 10, 50, and 100 m)

- Analytic Signal of Vertical Integration of TMI

- Analytic Signal of TMI

- Vertical Derivative of TMI

- Elevation (Shaded and contours)

Andres, Cinabrio Norte) and Exploration Targets (Campo Velado, La Higuera, St

Elvira, Inferillo)

Data Analysis

Analysis of the data indicates that remanent magnetism is likely present in some

areas. Consequently, the data were modelled with both the UBC MAG3D and the

Magnetic Vector Inversion (MVI). The MVI inversions were provided by Ellis

Geophysical Consulting of Reno Nevada. Both inversions generated a 3D model of

the magnetic susceptibility that fit the observed total field magnetic data. The

magnetic susceptibility is directly related to the magnetite content of most rocks, so

the 3D susceptibility model provi des a strong model of the subsurface magnetite

distribution.

At the Cinabrio mine, (see Figure 2: Cinabrio MVI Inversion Plot) a moderately strong

magnetic response was identified on the west side of the main deposit that correlates

- 4 -

with mapped east dipping magnetic sedimentary horizons which host the copper

mineralization. The 3D inversions also confirm the strongest observed magnetic

anomalies are at surface and weaken to the east due to the steep dip of the magnetic

zones. Similar magnetic signatures were identified at the San Andres and Cinabrio

Norte resources. The San Andres magnetic signature is shallow with limited depth

extent around 200m that correlates well with the geological interpretation that San

Andres is the off-faulted upper portion of the Cinabrio deposit.

Several magnetic anomalies appear similar in size and amplitude to the Cinabrio Mine

magnetic signature. These magnetic anomalies correlate with local historic copper

oxide mine workings and with exploration targets that had been identified by earlier

surface g eological mapping, prospecting, and rock sampling by BMR prior to the

magnetic survey. Much of the mapped and prospected areas had not previously been

explored by previous operators on the Cinabrio concessions. Battery technical staff

identified several surface anomalies including La Higuera, Salguera , St. Elvira and

Campo Velado.

The La Higuera target, located east of Cinabrio, hosts the largest and strongest

magnetic anomalies that consist of a larger response in the center flanked by

anomalies to the west and east. Each magnetic target is composed of multiple smaller

anomalies indicting both widespread and concentrated magnetite distribution.

Additional ground follow-up is being planned by BMR geologists.

North of La Higuera , is the Salguera target where NW to NNW trending magnetic

anomalies correlate well with mapped sedimentary stratigraphy, particularly the

northern part of Salguera which ha d been previously identified by BMR as an

exploration target. The stronger anomalies detected south of the road have not been

previously identified as exploration targets. These strong, east dipping magnetic

lineaments are interpreted to be associated with the same magnetic sedimentary

unit. Further detailed field investigations are planned.

In the northern part of the survey grid, the Campo Velado target is associated with

relatively narrow magnetic anomalies with limited depth extent. These magnetic

responses are weaker and less well-defined but there is an interesting NNE trending

structural target that BMR geologists believe warrants further investigation.

The St Elvira target situated in the southwest part of the grid hosts multiple strong

anomalies typically striking from NW to NS. The character of this anomaly is

somewhat different from the Cinabrio area, indicating that the magnetic source and

bedrock lithology may be different. This magnetic target coincides with a number of

historic oxide copper workings. The regional NW trending fault, locally known as the

Inferillo Fault, coincides with a strong magnetic linear feature. Another magnetically

anomalous zone, “Inferillo”, is observed to th e NW of the fault. Some of the linear

anomalies in this area resemble the anomalies near Cinabrio, so it is possible that

the favourable sedimentary sequence is present. Shallow colluvium covers many of

the anomalous areas.

Summary

The magnetic survey has clearly delineated a magnetic signature for the know n

deposits (Cinabrio, San Andres and Cinabrio Norte) and significantly enhanced the

prospectivity of the La Higuera, Salguera, Campo Velado and St Elvira Inferillo

targets.

Peter Doyle, Vice President of Exploration stated “We were very pleasantly surprised

by how well the 3D inversions of the magnetic surveys corresponded with the known

resources delineated by resource drilling. This leads us to believe that following up

on the known surface targets (La Higuera, Salguera, St. Elvira and Campo Velado)

- 6 -

with the most similar magnetic signatures to the Cinabrio mine, and the San Andres

and Cinabrio Norte resources could lead to new zones that deserve to be further

investigated and eventually drilled. Additionally, the 3D inversion of the magn etic

survey produced a new blind target called Inferillo that we intend to explore further.

We look forward to following up on these targets and reporting significant results to

the market”.
