Battery Mineral Resources Announces Intercept of 102 Meters Grading 1.41% Copper, at Dalmacia Target at Its Punitaqui Mine

Battery Mineral Resources Corp. (TSXV: BMR) (OTCQB: BTRMF) ("Battery" or "BMR" or the "Company") is extremely pleased to announce encouraging drill core assay results from the on-going 2021 exploration and in-fill drill program focused on extensions of the Cinabrio orebody, the Dalmacia and San Andres targets within the Punitaqui mine complex ("Punitaqui") in Chile. Punitaqui is slated for resumption of copper concentrate production in mid to late-2022.

Dalmacia is in the southern portion of the Punitaqui area about 6 kilometers south of the Punitaqui copper processing plant. The Dalmacia target has underground mining access, partially delineated mineralized zones and is targeted as a potential new source of ore feed to the Punitaqui ore concentration plant (see Figure 1).

Highlights

• At Dalmacia, a total of 6,504 meters in 33 holes have been completed and drilling continues. New assay results include the following drillholes (see Table 1):

• DS-21-08: 102 meters ("m") grading 1.41 percent copper ("% Cu") including 78m at 1.67% Cu and 16m at 3.52% Cu;
  
• DS-21-11: 24m at 1.04% Cu including 6m at 1.95% Cu;
• DS-21-12: 11m at 0.82% Cu;
• DS-21-13: 18m at 1.61% Cu and 12m at 2.13% Cu;
• DS-21-14: 15m at 1.16% Cu and 9m at 1.53% Cu;
• DS-21-16: 8m at 5.29% Cu and 8m at 3.53% Cu.

• Four diamond drills in operation at Punitaqui - two drills at Dalmacia and two drills at Cinabrio Norte (a potential extension of the Cinabrio orebody).
  
  
• At San Andres, the Phase 1 program resulted in the completion of 8,156m of drilling in 38 holes. All samples have been dispatched for analysis with assay results pending for the final six holes. An update of the 3D geological model is being completed which will be followed by a resource estimate by JDS Energy and Mining. A sample of previously published results include the following drillholes:

• SAS-21-03: 11m at 1.39% Cu;
• SAS-21-04: 16.7m at 1.37% Cu;
• SAS-21-14: 12.8m at 1.44% Cu;
• SAS-21-21: 13m at 0.96% Cu;
• SAS-21-27: 11m at 2.16% Cu;
• SAS-21-29: 16m at 1.49% Cu.

Battery CEO, Martin Kostuik states; "These drilling results, particularly from our Dalmacia target, are far better than expected. 102 meters of 1.41 percent copper is an outstanding result as we continue piece together this untapped area of Punitaqui. We are very pleased with the progress of the Dalmacia drill program which is shaping up to give Dalmacia strong potential to be a significant contributor to the future of the Punitaqui mine. Continued results like these leading to the planned restart of our former producing Punitaqui copper mine in Chile will give our investors an opportunity to participate in a potentially significant re-rating in BMR's valuation as we transition from development to operations and positive cash flow. We look forward to providing further exciting updates from the drill program as we continue to progress."

Punitaqui Copper Mine

Punitaqui is a former producing copper mine located in the Coquimbo region of Chile with an eight-plus year operating history within which up to 25 million pounds of copper in concentrate were produced annually. Punitaqui was acquired by BMR via a private placement equity financing closed on July 13, 2021. BMR began developing the project immediately by initiating a drilling program, operating and environmental permit modifications and engineering studies with the intention of restarting copper production in 2022.

Dalmacia Drill Program

The Dalmacia target is in the southern portion of the Punitaqui area about 6 kilometers south of the Punitaqui processing plant (see Figure 1). The first drilling occurred in 1993-1994 when 49 reverse circulation ("RC") holes totaling 9,972m were completed. Historic exploration drilling at Dalmacia North has been completed at a grid spacing of 25m x 25m, and 15m x 15m at Dalmacia South. Prior to the 2021 program, 229 drill holes (98 RC holes and 131 diamond core holes) had been drilled for a total of 53,294m.

The geological setting of the Dalmacia target is different from the Cinabrio orebody which is located 20 kilometers to the north. Dalmacia is situated within a roof-pendant of volcanic rocks, with minor calcareous intercalations of Middle to Upper Jurassic age. This volcano-sedimentary complex is intruded by younger aged granites located in a reverse fault.

Copper-gold mineralization is related to regional structures and deformation zones, developed in the contacts between granite, sub-volcanic andesitic porphyry intrusives and volcano-sedimentary rocks. Controls on mineralization include small scale shear zones, intrusive contacts, vesicular andesites and alteration zones. These controls have different geometries leading to complex orebody shapes. High grade copper mineralization occurs in small high-grade pods which locally occur in clusters enveloped in low grade mineralization.

The upper portion of the Dalmacia target is accessed via a portal and an underground ramp with limited level development. The current Phase 1 drill program is designed to infill and confirm the continuity of mineralization between previous drilling and includes a series of step-out holes to test the potential adjacent to the main zone of copper-gold-silver mineralization as defined by historic drilling.

To date, a total of 6,504 meters in 33 holes completed with an additional 5 holes / 600m of infill and step out drilling is planned to complete the Phase 1 program (see Figure 2). Complete assay results were recently received for seven holes: DS-21-08, DS-21-10, DS-21-11, DS-21-12, DS-21-13, DS-21-14, and DS-21-16 (see Table 1). A summary of the target rationale and results for these new drillholes is below.

48m - 150m downhole

Drillhole DS-21-08 was designed as an infill hole to test the up-dip extent of mineralization intersected in historic hole DAL-20 (27m at 0.91% Cu) and DS-14-17 (27m at 1.84% Cu) and the down-dip extent of mineralization intersected in DS-11-08 (12.6m at 2.12% Cu). The new hole intersected both disseminated and veinlet chalcopyrite and bornite between 48 - 140m downhole. Significant mineralized zones included 102m at 1.41% Cu from 48m downhole including 78m at 1.67% Cu and 16m at 3.52% Cu. The up-dip test found minor mineralization and the down-dip test successfully intersected strongly mineralized copper of both disseminated and veinlet chalcopyrite and bornite between 48m – 150m downhole. Sizable and strongly mineralized zones included 102m at 1.41% Cu from 48m downhole including 78m at 1.67% Cu and 16m at 3.52% Cu. The DS-21-08 intersection is made up of 5 different high-grade zones within a broader section of moderately to weakly mineralized host rock. The mineralization is interpreted as contiguous and can be correlated with intersections in nearby, adjacent historic drillholes. The results clearly demonstrate that these higher-grade zones interspaced with moderately to weakly mineralized copper mineralization represent a viable target model for future resource definition drilling at Dalmacia. Close spaced drilling is required to define potential copper resources with unmineralized to moderately mineralized rock in between the high-grade pods.

Drillhole DS-21-10 was drilled as a vertical step-out hole angled under surface workings. The hole intersected variably altered andesites with 0.1% - 1% pyrite and 0.01% - 0.05% copper. A high-grade copper intercept was reported from a vein zone; 2m at 2.40% Cu from 138m downhole.

Drillhole DS-21-11 successfully tested the area 18 meters below and west of historic intercept DAL-32 (17m at 2.17% Cu). Mineralized intercepts include 2m at 1.14% Cu from 59m downhole, 24m at 1.04% Cu from 78m including 10m at 1.06% Cu from 78m and 4m at 1.60% Cu from 78m and an intercept of 6m at 1.95% Cu from 96m.

Drillhole DS-21-12 is an infill hole designed to test the area 15 meters above an intercept in historic hole DAL-32 (17m at 2.17% Cu). The hole cut moderate chalcopyrite-bornite mineralization above the historic intercept. Results include 5m at 0.62% Cu from 116m downhole, 2m at 0.95% Cu from 143m and 11m at 0.82% Cu from 161m.

Drillhole DS-21-13 successfully tested a "drilling gap" between historic hole DS-11-10 that intersected weak, copper mineralization and historic hole SD-08 (8m at 1.86% Cu). Mineralized intercepts include 18m at 1.61% Cu from 44m downhole, 12m at 2.13% Cu from 135m downhole including 8m at 2.95% Cu and an interval of 5m at 3.26% Cu from 157m downhole as well as an intercept of 7m at 1.87% Cu from 181m.

Drillhole DS-21-14 was drilled obliquely over the top of the high-grade intercept drilled in DS-21-06 (29m at 1.45% Cu including 14m at 2.44% Cu). DS-21-14 successfully intersected a strongly mineralized zone 10 meters above and 11 meters north of the DS-21-06 intercept. Significant chalcopyrite and bornite mineralization between 73m and 209m including 9m at 0.74% Cu from 73m downhole including 4m at 1.03% Cu from 78m, 15m at 1.16% Cu from 145m including 7m at 1.44% Cu from 145m and an interval of 9m at 1.53% Cu from 186m and another intercept of 4m at 1.50% Cu from 205m.

Drillhole DS-21-16 is an infill hole designed to test continuity of a south plunging mineralized zone between historic holes SD-22 (17m at 2.57% Cu) and DS-14-13 (27m at 1.62% Cu). The new hole established continuity by intercepting two high-grade copper intervals that include 8m at 5.29% Cu from 74mdownhole and 8m at 3.53% Cu from 102m.

The infill drilling results to date have defined several structurally controlled, steeply dipping shoots of high-grade mineralization. In addition, the step-out drilling has identified high-grade mineralization beyond the northern edge of the main drilling grid.
