Battery CEO Martin Kostuik states; "Our recent acquisition of the 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-flowing. The development of Punitaqui towards a restart is progressing well on all fronts such as drilling, engineering and permit modifications and we look forward to presenting the restart plan for the mine in Q1 2022. In addition, as the drilling program progresses across the various mineralized zones, we are excited to report the first of many results for Dalmacia. These new step-out drilling results demonstrate that previously defined mineralized zone remains open to the north and the 2021 infill drilling has confirmed the presence of a number of high-grade shoots.
This program has the potential to provide the Company with an additional source of copper ore along with existing ore at the Cinabrio mine and the mineralization at the San Andres target. We look forward to providing further exciting updates for the drill program as we progress towards a potential near term resumption of operations and cashflow at Punitaqui."
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 produced up to 25 million pounds of copper in concentrate annually. Punitaqui was recently acquired by BMR via a private placement equity financing announced on July 13, 2021. BMR began developing the project immediately by initiating a drilling program, operating and environmental permit modifications and engineering studies.
Dalmacia Drill Program
- Program comprises both confirmation and step-out diamond core drilling
- Currently, two diamond core drills are in operation at Dalmacia.
- Nineteen holes have been completed for 3,892 meters of diamond core drilling and the program continues
The Dalmacia target is located in the southern portion of the Punitaqui area about 6 kilometers south of the Punitaqui processing plant (see Figure 1 and Figure 2). 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 at a spacing 15m x 15m in the south. In total, 229 drill holes (98 RC holes and 131 diamond core holes) have been drilled for a total of 53,294m.
The geological setting of the Dalmacia target is different from both the Cinabrio mine and San Andres target which are 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.
The current 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 mineralization as defined by historic drilling. The infill drilling results to date have defined several steep dipping shoots of high-grade mineralization. Step-out drilling has identified high-grade mineralization beyond the northern edge of the main drilling grid.
Drillhole DS-21-03 was designed as an infill drill hole to test Dalmacia mineralization in the south-central portion of the target 100m northeast of the mine portal. It was drilled in a northeast direction between drill holes DS-14-09 (9m at 1.62% Cu) and DAL-09 (7.0m at 1.66% Cu). DS-21-03 resulted in one intercept; 15m grading 1.01% Cu and 1.2g/t Ag from 46m downhole including 4m at 2.47% Cu, 3.1g/t Ag and 0.05g/t Au from 46m.
Drillhole DS-21-06 was designed to test Dalmacia mineralization beyond the northern edge of the known mineralized zone. The hole was drilled north of drill hole DAL-38 which intersected 16 meters of 1.24% Cu from 59 meters and DS-11-04 which intersected 12 meters of 1.94% Cu from 22 meters and 11.4 meters of 1.01% Cu from 205 meters. Drillhole DS-21-06 resulted in numerous intercepts of mineralization between 37 and 262 meters downhole. These include 16m grading 1.15% Cu, 0.6g/t Ag and 0.06g/t Au from 37m downhole, 95m at 0.78% Cu from 167m downhole including 14m at 2.44% Cu and 0.7g/t Ag from 197m and 19m at 1.10% Cu and 0.6g/t Ag from 243m downhole.
The results from DS-21-06 indicate that high-grade mineralization at Dalmacia is open to the north. Follow-up drilling is underway to further define the mineralization discovered in DS-21-06. Sample assay results, reported herein, are from DS-21-03 & DS-21-06 from the Dalmacia target (see Table 1 and Figure 2).

Background - Dalmacia Target
The first modern drilling of the Dalmacia target occurred in 1993-1994 when 49 reverse circulation ("RC") holes totaling 9,972m were completed.
In 2007, Compañia Minera Punitaqui carried out ground magnetics and induced polarization surveys followed by RC drilling program (49 holes/11,473m). Between 2011 - 2018 a total of 131 diamond core drillholes were completed at Dalmacia for a total of 31,849m.
The Dalmacia exploration drilling has been completed at a grid spacing of 25m x 25m in the north and at 15m x 15m in the south. In total, 229 drill holes (98 RC holes and 131 diamond core holes) have been drilled for a total of 53,294m with 35,201 samples analysed.
The Dalmacia target is located within a roof-pendant of volcanic rocks, with minor calcareous intercalations of Middle to Upper Jurassic age. This volcano-sedimentary complex is intruded by 105-130Ma granitoids located in a reverse fault.
The Dalmacia copper-gold mineralization is hosted in the Agua Salada Complex, consisting of andesites, ocoites (porphyritc andesites) with white phenocrysts and ocoites with black phenocrysts. The ocoites are conformable to stratigraphy ("sill-type") and in plan show an elliptical to sub-circular morphology.
The copper-gold mineralization occurs as veins, fracture infillings and disseminated oxides and sulphides. The known strike length of the mineralized zone is at least 1,500m and up to 300m wide with depths greater than 500m. Additionally, mineralization is related to regional structures and deformation zones, developed mainly in the contacts between granitoids and volcano-sedimentary rocks.
The mineralisation at Dalmacia is hosted in andesites, and andesitic porphyry dykes with both black and white phenocrysts. The copper-gold mineralization is structurally controlled and occurs as veins, fracture infillings and disseminated oxides and sulphides. The known strike length of the mineralised zone is at least 1,500m and up to 300m wide with depths greater than 500m.
At Dalmacia, oxide mineralisation includes chrysocolla, atacamite, neotocite and cuprite. Primary mineralisation consists of chalcopyrite and bornite with pyrite. Secondary mineralisation includes chalcocite and bornite.
Locally, the copper mineralization at Dalmacia is hosted within a stratigraphic package that includes sedimentary rocks, andesites, and tuffs, intruded by ocoites and late intrusive diorite (dykes and stocks), which have generated hornfels. The alteration related with the mineralization varies from potassium feldspar, actinolite, secondary biotite, chlorite, green sericite to sericite-quartz/sericite.
The main copper mineralization occurs immediately after the ocoites undergo a late phase of chalcosodic alteration (quartz-albite-actinolite-epidote, "white" ocoites) with the destruction of magnetite and superimposed onto an earlier event of black albite, magnetite and silicates (black ocoites).
The upper portion of the Dalmacia target is accessed via a portal and a limited underground ramp and level development.
At Dalmacia, the copper-gold mineralization is hosted by andesitic volcanic rocks, with minor sandstone layers, intruded by subvolcanic dikes, sills and small stocks of porphyritic andesite (ocoites), and diorite. The mineralization is interpreted to be controlled by both lithologies and fault structures. Lithologies favorable to mineralization include vesicular porphyritic andesites and sandstone units. At least two sets of steeply dipping shear zones are thought to be fluid pathway for the hydrothermal fluids which produced the mineralization. Zones of moderate to intense biotite alteration are commonly associated with the copper mineralization and locally contain moderate grade disseminated chalcopyrite-bornite mineralization.
