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

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):
  • 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
  • SAS-21-35: 25.1m at 0.54% Cu including 6.9m at 1.10% Cu
  • SAS-21-34: 9.2m at 1.57% Cu
  • SAS-21-31: 2.8m at 1.74% Cu
  • SAS-21-25: 4.6m at 0.82% Cu
  • SAS-21-32: 4m at 1.44% Cu
  • SAS-21-38: 2.2m at 1.10% Cu
  • SAS-21-33: 2.0m at 0.73% Cu
  • 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 sections 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 breccias 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 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 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:
  • SAS-20-07: 16m at 2.52% Cu
  • SAS-07-50: 11m at 2.39% Cu
  • SAS-20-01: 11m at 2.16% Cu
  • 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, the 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.
