Battery Mineral Resources Corp. (TSXV: BMR) (“Battery” or “BMR” or the “Company”) announces that it has completed a seven hole – 682.00 metre diamond drill program on its 100% owned Bald Rock prospect in the Gowganda Project area (Figure 1).
- The Bald Rock target comprises an area of extensive historic stripping and channel sampling that yielded intervals grading 51.60 grams per tonne silver (“g/t Ag”), >1.00 percent cobalt (“% Co”) and 1.37 percent copper (“% Cu”) over 0.58 metres (“m”), and 4.19g/t Ag, >0.30% Co, and 1.13% Cu over 2.05m;
- Rock sampling by BMR field crews of the stripped outcrop that was channel sampled in 2011 returned assays of 41.30g/t Ag, 1.53% Co and 7.65% Cu;
- No record or field evidence of any historic diamond drilling;
- Five holes are designed to test the strike and depth extent of the known 10m wide zone of altered and mineralized zone exposed in the stripped outcrop area, and one hole will target the projected intersection of the Bald Rock vein corridor, the vein system hosting the 3,317ounce per ton (“oz/t”) silver rock grab sample result as well as the shaft vein system;
- One hole tested the vein mineralisation exposed at the prospect shaft/pit to the northwest of the stripped outcrop area;
- The final hole was drilled to test the vertical continuity of high-grade silver vein mineralisation identified in historic rock grab sampling (3,317oz/t silver assay) northwest of the stripped outcrop;
- Drilling results and assays are expected by end of July, 2021.
About the Bald Rock program
The Bald Rock prospect is situated in Lawson Township and is also referred to as the LaCarte or Silver Leaf showing. It consists of a shaft that was sunk in the 1930s and numerous pits and mechanically stripped outcrops which have been periodically examined over the years.
In 2010, a stripped outcrop 250m south of the shaft was rock grab sampled and yielded an assay of 3,317oz/t silver (113,725g/t Ag). In 2011, follow-up exploration consisted of a channel sampling program on the Bald Rock showing located approximately 500m south of the shaft. The channel sampling returned several anomalous mineralized zones including;
- 51.60g/t Ag, >1.00% Co and 1.37% Cu over 0.58m,
- 4.19g/t Ag, >0.30% Co, and 1.13% Cu over 2.05m.
Reconnaissance rock grab samples collected by BMR from a prospect pit adjacent to the 2011 channel samples yielded assays of 41.30g/t Ag, 1.53% Co and 7.65% Cu (Photo 1). Stripping and detailed mapping of the outcrop revealed that the altered and mineralized corridor is at least 10m wide, extends over a strike length of 40m and is open along strike in both directions.
The vein at the shaft, which was exposed by a pit and stripping strikes N330oE and yielded an assay of 0.93% cobalt and 5.68g/t silver from a BMR rock grab sample of the vein. The orientation of the vein exposed by the stripping and produced the 3,317oz/t silver assay is located 250m south of the shaft and strikes N350oE while the main Bald Rock vein system located further south strikes N050oE.
A seven-hole, 682.00m diamond drill program was completed in late June 2021. Five holes tested the depth and strike extent of the Bald Rock vein exposed in the stripped outcrop. The sixth hole target the intersection of three mineralised vein sets and a seventh hole targeted a historic high-grade silver grade silver rock sample result (Figure 2). A total of 189 drillcore samples were submitted for assay.
Battery CEO, Martin Kostuik, states, “The detailed mapping and sampling at Bald Rock prospect have identified a previously undrilled, 10-metre wide altered and mineralized zone that is open along strike and at depth. We are looking forward to the assay results from the drill testing of this target located southeast of the former producing Gowganda mining camp.”
The Gowganda mining camp was one of three historic silver-cobalt districts in Canada’s Cobalt Embayment situated in northeastern Ontario about 6 hours drive north of Toronto. Estimated historic production from the Gowganda camp (1910-1969) was 60 million ounces of silver and 1.3 million pounds of bi-product cobalt. This production was sourced from high-grade silver-cobalt veins hosted in Proterozoic Nipissing diabase sill-like intrusions. Thirty-seven mineral occurrences are present on the BMR’s Gowganda block which have an extensive exploration & mining history dating back to 1908 when silver was first discovered at Miller Lake.
The Gowganda Project totals 1,138 mining claims and 4 mining leases covering 22,693 hectares (226 square kilometres) in two main blocks. BMR’s holdings include 4 of the 5 past producers in the Gowganda Camp including the Capitol, Bonsall, Millerett and Miller Lake-O’Brien mines.
The Gowganda block bedrock geology consists of that intrude Proterozoic Huronian Cobalt Group sediments intruded by Nipissing diabase sills and dykes. The oldest rocks at Gowganda are Archean greenstone metavolcanics – metasediments and/or granitic basement. Late diabase dykes cut all Archean and Proterozoic lithologies.
Most of the polymetallic silver-cobalt-nickel vein occurrences are hosted in the Nipissing diabase although both Archean metavolcanic and Cobalt Group sedimentary rocks have also been recorded to host veins. Most of the productive veins were hosted in the upper half, or hanging wall, of the Nipissing diabase sills. Mineralized quartz-calcite veins are typically vertical to steeply dipping. Vein widths range from mm-scale to 1 metre in width. The highest-grade ores were commonly mined at structural/vein intersections.
Mineralized zones occur as sheets of native silver and finer-grained iron-cobalt-nickel arsenide minerals in calcite gangue, often with minor comb-textured quartz along the vein margins.

Sample preparation, analysis and security procedures applied on the BMR exploration projects is aligned with industry best practice. BMR has implemented protocols and procedures to insure high quality collection and management of samples resulting in reliable exploration assay data. BMR has implemented formal analytical quality control monitoring for all of its field sampling and drilling programs by inserting blanks and certified reference materials into every sample sequence dispatched.
Sample preparation is performed by ALS Minerals Laboratories (“ALS”) in Sudbury, Ontario and sample analyses by ALS in North Vancouver, British Columbia. 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 in Sudbury. Samples are logged in a sophisticated laboratory information management system (LIMS) for sample tracking, scheduling, quality control, and electronic reporting. Samples are dried prior to crushing. The samples are crushed to 70%
