Battery Mineral Resources Corp. 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 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. Highlights · New assay results for Cinabrio Norte include the following: o CNN-22-08: 33.4 meters at 1.08% Copper 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 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 to 45 holes, totaling 11,000m which will test 400m of strike length to a depth of 330m. 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 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 and, most notably, confirmed the presence of TSU for over 200m of strike length with significant copper sulphide mineralization .

The current drilling was planned as a series of step-out holes to test the TSU 400m along strike to a depth below surface 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 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 .

Significant intercepts reported earlier from the phase 1 drilling include: o CNN-22-01: 26m at 1.28% Cu o CNN-21-02: 13m at 1.36% Cu including 7.6m at 2.08% Cu o CNN-21-06: 53m at 0.91% Cu including 20.8m at 1.14% Cu o CNN-21-07: 9.7m at 0.70% Cu o CNN-21-11: 7m at 1.21% Cu 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.
