Battery Mineral Resources Continues to Deliver Favorable Drilling Results at Punitaqui Copper MINE

BATTERY MINERAL RESOURCES CONTINUES TO DELIVER FAVORABLE

DRILLING RESULTS AT PUNITAQUI COPPER MINE

Vancouver, British Columbia – (February 22, 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 on-going 2021 exploration

and in -fill drill program at the San Andres zone of the Punitaqui mine complex

(“Punitaqui”) in Chile . Punitaqui is slated for resumption of copper concentrate

production in the second half of 2022.

San Andres is the “normal” fault displaced upper portion of the adjacent Cinabrio

copper deposit that is part of Punitaqui. Cinabrio was the primary source of copper

for the Punitaqui mill which typically produced between 20 and 25 million pounds of

copper annually and was operated for nine plus years by each of Glencore and Xiana

Mining. The San Andres zone is one of several historic zones within BMR’s Punitaqui

project with partially delineated resource potential and established underground

access. Historic wide-spaced drilling completed by the previous operators between

2011- 2020 totaled 9,676 meters in 76 holes.

Highlights

• The San Andres drill program is designed to confirm resource potential

identified over a 600-meter (“m”) strike length by previous drilling programs.

• Final assay results from remaining San Andres drillholes have been returned

with encouraging results as follows (see Table 1):

o SAS-21-36: 37.6 meters (“m”) at 1.36% Copper (“Cu”) including

27.4m at 1.55% Cu and including 14.7m at 2.12% Cu

o SAS-21-35: 25.1m at 0.54% Cu including 6.9m at 1.10% Cu

o SAS-21-34: 9.2m at 1.57% Cu

o SAS-21-31: 2.8m at 1.74% Cu

o SAS-21-25: 4.6m at 0.82% Cu

o SAS-21-32: 4m at 1.44% Cu

o SAS-21-38: 2.2m at 1.10% Cu

o SAS-21-33: 2.0m at 0.73% Cu

o SAS-21-37: 2.1m at 0.66% Cu

• 8,156m of drilling in 38 diamond core holes were completed in the Phase 1

drill program at San Andres and final complete multi-element analytical results

have been received for all samples.

• Drilling tested the Target Stratigraphic Unit (“TSU”) sediments to the north

and south along strike and at depth. In total, 36 holes reached target depth and

intersected the favorable mineralized horizon. Of those, 29 drillholes produced

significant copper intercepts during the program.

• Cross-sectional geological interpretation section s have been compiled and a

three-dimensional San Andres zone geological model has been completed.

• The geological model and corresponding assay database have been forwarded

to JDS Energy & Mining to complete a resource estimate for San Andres.

• A composite drillcore metallurgical sample from the San Andres zone was

shipped to SGS Lakefield in Ontario where preliminary metallurgical testwork

is underway.

Battery CEO Martin Kostuik states; “The completion of the first phase of drilling

at the San Andres zone brings us one step closer to providing the market

with BMR’s maiden resource statement for Punitaqui . We believe these new

drilling results complement the prior successful drilling at San Andres and, together,

demonstrate that this drill program has the potential to provide the Company with

an additional source of copper ore for the Punitaqui mill and longevity for the project.

We look forward to providing further exciting updates for the drill program as we

progress towards the 2022 resource update and funding the potential near term

resumption of operations and cashflow at Punitaqui”

San Andres Drill Program

The San Andres target is a zone of copper mineralization located 500m southwest of

the high-grade Cinabrio deposit mined by Glencore and Xiana Mining (see Figure 1).

San Andres is a tabular sedimentary horizon 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, volcanoclastic sandstone ,

conglomerates and b reccias and tuff breccias. There is a variable component of

syngenetic pyrite. The horizon dips 40 to 50 degrees to the east and is cut -off at

depth by the moderately west dipping San Andres fault (see Figure 3).

Mineralization consists of veinlets and i rregular 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 other faults with a wide range

of orientations. The fundamental orientations identified to date include:

• moderately west dipping splays of the San Andres fault , generally with

downward and westward movement

• steep dipping northeast to northwest trending faults with both sinistral and

dextral offsets

• Faults parallel and sub-parallel to stratigraphy

• Historic wide-spaced drilling completed by the previous operators between

2011- 2020 totaled 76 holes / 9,676.65m. Significant historic drilling

intercepts (see Table 3) included:

o SAS-20-07: 16m at 2.52% Cu

o SAS-07-50: 11m at 2.39% Cu

o SAS-20-01: 11m at 2.16% Cu

o SAS-20-08: 17m at 1.74% Cu

• BMR’s Phase 1 San Andres diamond drilling program comprised of 8,156

meters of diamond core drilling in 38 drill holes (See Figure 1 and Figure 2).

Sample assay results, reported herein, are from the final nine drill holes and are in

addition to the results reported previously from the first 29 drillholes completed at

San Andres (see Table 1 and Table 2 below).

SAS-21-37: 2.1m at 0.66% Cu from 210.1m

SAS-21-38: 15m at 0.40% Cu from 218m including 2.2m at 1.10% Cu from

230.8m.

Drillhole SAS-21-25 was designed to test San Andres targeted stratigraphic unit

(“TSU”) 60m down-dip from the SAS -21-08 intercept (5.3m at 1.39% Cu and a

second interval of 3.8m at 1.85% Cu). This down-dip test resulted in an intercept

of 4.6m at 0.82% Cu from 245m confirming the mineralized zone at depth at about

the same width.

Drillhole SAS-21-31 targeted the TSU about 50m up-dip from hole SAS-21-06 that

intersected an 18.2m downhole interval of the TSU consisting of shales and

volcanoclastic sandstone and conglomerates with abundant pyrite and trace

chalcopyrite. Further down, t he hole intersected a thick section of the TSU with

abundant pyrite with weak copper sulphides that yielded an intercept of 2.8m at

1.74% Cu from 169.8m.

Drillhole SAS-21-32 was planned as an infill hole targeting the gap between SAS-

21-04 (16.7m grading 1.37% Cu including 11.7m at 1.64% Cu and a second

interval of 9.0m at 1.75% Cu) and SAS-21-20(2.4m at 0.70% Cu). This hole

successfully intersected 36m of the TSU including a 7m interval of mineralized

shaley sediments. Two mineralized intercepts were reported 5.3m at 0.70% Cu

from 212m and 4m at 1.44% Cu from 230m.

Drillhole SAS-21-33 targeted the gap west of the underground workings in the

northern part of the San Andres zone. The drillhole intersected a 36m section of the

TSU with disseminated chalcopyrite mineralization. A narrow, mineralized intercept

of 2m at 0.73% Cu from 99m was reported.

Drillhole SAS-21-34 was designed to test the “drilling gap” between SAS-21-14

(28.1m at 0.98% Cu including 10.1m at 1.44% Cu and a second intercept of

9.4m grading 1.24% Cu) and SAS-21-07 ( 3.4m at 2.10% Cu ) and a second

interval of 4.0m at 1.56% Cu). SAS-21-34 intercepted 32m of the TSU with variable

chalcopyrite and bornite sulphides that resulted in an encouraging assay of 9.2m at

1.57% Cu from 232m.

Drillhole SAS-21-35 tested the “drilling gap” between the high -grade intercept in

SAS-21-27(11m at 2.16% Cu) and SAS-21-17 (3.6m at 1.04% Cu). The hole cut

a 37m long section of the targeted stratigraphic unit with pyrite and chalcopyrite.

The mineralized horizon produced a broad anomalous intercept of 25.1m at 0.54%

Cu from 206.9m including 6.9m at 1.10% Cu from 225.1m.

Drillhole SAS-21-36 was designed to test the “drilling gap” between SASA-21-03

(11.0m at 1.39% Cu including 8.0m at 1.63% Cu) and historic hole SAS-20-02

(16m at 1.05% Cu). Hole SAS-21-36 positively intersected a strongly mineralized

51m of the TSU with pyrite and chalcopyrite that produced assays of 37.6m at

1.36% Cu from 178.4m including 27.4m at 1.55% Cu from 178.4m including

14.7m at 2.12% Cu from 191.1m and 7.1m at 1.16% Cu from 209.0m and

including 3.2m at 1.93% Cu from 212.9m.

Drillhole SAS-21-37 was designed to test the “drilling gap” between SAS -21-03

(11.0m at 1.39% Cu including 8.0m at 1.63% Cu ) and SAS -21-23(2.8m at

1.00% Cu). The hole intersected 10.2m of the TSU with pyrite and chalcopyrite. The

hole successfully returned an intercept of 2.1m at 0.66% Cu from 210.1m.

Drillhole SAS-21-38 was designed to test the “drilling gap” between SAS -21-14

(28.1m at 0.98% Cu including 10.1m at 1.44% Cu and a second intercept of

9.4m grading 1. 24% Cu) and SAS-21-24(3.0m at 0.82% Cu). The infill hole

successfully intersected the TSU within which were 6.4m of shaley sediments with

pyrite and copper sulphides of the TSU that produced 15m at 0.40% Cu from 218m

including 2.2m at 1.10% Cu from 230.8m.
