Vancouver, British Columbia--(Newsfile Corp. - September 12, 2024) - 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 new 2024 underground exploration and in-fill drill program at the Punitaqui mine complex ("Punitaqui") in Chile.
Highlights
- Assay results from drillholes (see Table 1) have returned with encouraging results as follows:
- Drillhole CM-24-11: 18.3 meters ("m") grading 2.6 percent ("%") copper total ("CuT") and 11 grams per tonne ("g/t") silver ("Ag") including 14.9m at 3.1% CuT & 13g/t Ag drilled as an infill hole delineated the extent of the mineralization intercepted in historic drillholes CM-0-19-05 and CM-0-19-07
- CM-24-12: 6.4m grading 0.9% CuT and 5g/t Ag drilled as an extensional hole defined the northern strike extent of the planned extraction area
- CM-24-13: 23.1m at 2.0% CuT & 14g/t Ag drilled as an infill hole confirmed the extent of the mineralization intercepted in historic drillholes CM-0-19-05 and CM-0-19-07
- CM-24-14: 1.5m at 0.6% CuT & 1g/t Ag and 2.9m at 0.5% CuT & 14g/t Ag drilled as an extensional hole confirmed the southern strike extent of the planned extraction area
- The 2024 Cinabrio drill program is designed to confirm resources identified by previous drilling programs and expand these resources along strike and at depth. All holes reached target depth and have intersected the targeted shale-mudstone horizon that hosts the copper mineralization.
- This phase of Cinabrio underground drilling targeted the Level 160 scheduled production area where 4 drillholes totaling 173.6 meters of diamond core drilling were completed (see Table 2 and Figure 1).
- The four holes were designed to confirm the modelled geology, mineralization and probe the contact zone between the lower mineralized shale unit and the underlying andesites within and adjacent to the planned extraction area (CM-24-11, CM-24-12. CM-24-13 and CM-24-14).
- This drilling confirmed copper grades and better delineated the extent of the mineralization in the lower shale unit and footwall andesite within and adjacent to the planned extraction area.
- These drill results have been added to the three-dimensional geology and resource models which BMR's mining engineers will use to update the current mine designs and optimize mining schedules.
- As of mid-August, the Cinabrio-San Andres underground drill program had resulted in the completion of 31 drillholes / 1,300.4m including 18 holes / 770.2m at Cinabrio.
- Drilling is ongoing and assay results for the remaining 11 Cinabrio drillholes are pending.
Battery Vice President of Exploration Peter Doyle stated, "These new, high-grade copper infill drill results not only confirm the copper grades predicted by our current geological model but also provide a more detailed understanding of the Level 160 target mineralization. The ongoing underground drilling continues to demonstrate encouraging results that highlight the potential of the Cinabrio mine."
During the current operational ramp-up period, the underground drilling program is focused on accessible targets within existing Inferred Resource to upgrade the resources to a higher resource category as well as targeting areas adjacent to Inferred Resource to potentially add new resources.
The 2024 drill plan allows for some flexibility in terms of timing and sequencing of target areas which permits the drilling to be shifted between the Cinabrio mine and the adjacent San Andres underground.
Cinabrio Mine
Sample assay results, reported herein, are from the second target tested as part of the underground drilling at Cinabrio. These four BMR drillholes are infill holes designed to verify and better delineate mineralization for the Level 160 target. Historic drillholes CM-0-19-05 and CM-0-19-07 drilled by Xiana Mining Inc. were both collared from a working above and to the north of the Level 160 planned production area and drilled sub-parallel the stratigraphy. Hole CM-0-19-05 intersected 1.2m at 0.5% CuT and 2.3g/t Ag from 30m and 4.4m at 1.9% CuT and 4.9g/t Ag. Drillhole CM-0-19-07 is interpreted to have drilled from the footwall andesite into the lower part of the overlying sedimentary sequence and then back into the footwall andesites. This hole intersected a mineralized zone in the shales in the lower part of the sedimentary sequence that yielded an intercept of 3m at 6.6% CuT and 46.9g/t Ag.
All four of the BMR drillholes were drilled from the footwall andesite upward through the TSU sedimentary unit and terminated at the old mine workings above the target area.
Drillhole CM-24-11 was designed to test the north-central part of the Level 160 planned production area. The drillhole encountered weakly mineralized andesite near the contact of the TSU sedimentary unit and then a well mineralized sequence of shales and sandstones near the bottom of the hole which was stopped prior to encountering an old underground working. Assay results reported included 18.3m grading 2.6% CuT and 11g/t Ag from 15.0m including 14.9m at 3.1% CuT & 13g/t Ag from 18.6m. The drill hole confirmed the presence of a significant zone of copper mineralization in the planned extraction area.
Drillhole CM-24-12 was planned to test the northern end of the planned extraction area. The drillhole encountered footwall andesite from 0m to 30.9m which was weakly mineralized at the top adjacent to the overlying TSU sedimentary sequence. From 30.9m to the bottom of the hole (44.0m), this drillhole encountered variably mineralized sandstones and shales. Assay intervals reported include 6.4m grading 0.9% Cu and 5g/t Ag from 34.9m. The drillhole confirmed the northern limit of mineralization within the planned extraction area.
Drillhole CM-24-13 tested the south-central part of the planned extraction area. The drillhole encountered footwall andesite from 0m to 13.3m which is well mineralized. From 13.3m to 27.1m the section intersected consisted of a sequence of mixed shales and andesitic volcanoclastics with variable mineralization. From 27.1m to the bottom of the drillhole (42.5m), the interval intersected well mineralized shales cut by an andesite dyke from 38.6m to 42.4m. Assay results include 23.1m at 2% CuT & 14g/t Ag from 12m. The drill hole confirmed the presence of a significant high-grade zone of mineralization in the planned extraction area.
Drillhole CM-24-14 was designed to test the southern extent of the planned extraction area. This drillhole intersected footwall andesite from 0m to 30.3m followed by a section of sandstones, shales and volcanoclastics from 30.3m to the bottom of the drillhole at 54.8m. The hole yielded two weakly anomalous intercepts; 1.5m at 0.6% Cu & 1g/t Ag from 17m and 2.9m at 0.5% CuT & 14g/t Ag from 44.5m. Drill hole CM-24-14 confirmed the southern margin of mineralization in the planned extraction area.

Background - Cinabrio Deposit
The Cinabrio copper deposit mined by Glencore and Xiana Mining was the main ore source for the Los Mantos processing plant for over 10 years. Cinabrio is the largest deposit mined to date and is part of the Punitaqui project which is situated within a 25km long mineralized district that is a classic IOCG and manto style copper belt that is comprised of manto and structural controlled copper-silver veins.
On October 3, 2022, BMR published an NI 43-101 resource for Cinabrio at a 0.70 Cu% cut-off.
- Indicated Sulphide Resource of 378,000 tonnes grading 1.55% CuT.
- Inferred Sulphide Resource of 90,000 tonnes at 0.98% CuT
In addition, Indicated resources for Cinabrio potentially recoverable pillars at a 0.70 Cu% cut-off.
- Undiluted Indicated resources of 1,027,000 tonnes at grading 1.51% CuT
- Diluted Indicated resources of 1,312,000 tonnes at 1.27% CuT
Note: Scientific and technical information pertaining to the San Andres Resource was extracted from the Company's NI 43-101 "Technical report on Punitaqui Copper Complex Coquimbo, Chile" dated as of September 30,2022 with an effective date of August 16, 2022, prepared by Garth Kirkham (Kirkham Geosystems Ltd.) an Independent Qualified Person in accordance with NI 43-101.
The Cinabrio historic workings encompass about 700 vertical meters from the ridge-top oxide workings to the lowest level of underground development. Within the underground mine level development is spaced vertically at about a 30 meter interval.
The Cinabrio deposit is a tabular sedimentary horizon known as the "Targeted Stratigraphic Unit" ("TSU") 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. Most of the copper mineralization is hosted in the shale units within the TSU package. The horizon dips 40 to 50 degrees to the east.
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 faults and dykes with a wide range of orientations.
Quality Control
Sample preparation, analysis and security procedures applied on the BMR exploration projects are aligned with industry best practice. BMR has implemented protocols and procedures to ensure high quality collection and management of samples resulting in reliable exploration assay data. BMR has implemented formal analytical quality control monitoring for all field sampling and drilling programs by inserting blanks and certified reference materials into every sample sequence dispatched.
Sample preparation is performed BMR Los Mantos Preparation Lab. Samples are dried then crushed to 70% < -2 millimeters and a riffle split of 250 grams is then pulverized to 85% of the material achieving a size of <75 microns. Sample pulps & rejects were then delivered to ALS Global - Geochemistry Analytical Lab in La Serana, Chile and sample analyses by ALS in Lima, Peru. ALS analytical facilities are commercial laboratories and are independent from BMR. All BMR samples are collected and packaged by BMR staff and delivered upon receipt at the ALS Laboratory. Samples are logged in a sophisticated laboratory information management system for sample tracking, scheduling, quality control, and electronic reporting. These prepared samples are then shipped to the ALS Laboratory in North Vancouver for analyses by the following methods:
- ME-MS61: A high precision, multi-acid digest including Hydrofluoric, Nitric, Perchloric and Hydrochloric acids. Analysed by inductively coupled plasma ("ICP") mass spectrometry that produces results for 48 elements.
- ME-OG62: Aqua-Regia digest: Analysed by ICP-AES (Atomic Emission Spectrometry) or sometimes called optical emission spectrometry (ICP-OES) for high levels of Co, Cu, Ni and Ag.
Certified standards are inserted into sample batches by ALS. Blanks and duplicates are inserted within each analytical run. The blank is inserted at the beginning, certified standards are inserted at random intervals, and duplicates are analysed at the end of the batch.
