MRE For The Berenguela Silver-Copper-Manganese Deposit

VANCOUVER – Aftermath Silver Ltd. announced a new Mineral Resource Estimate (MRE) for the Berenguela silver-copper-manganese deposit located in the Department of Puno in southern Peru. The current estimate confirms and expands Aftermath’s previous 2023 Mineral Resources and is based on the most extensive geological model of the Berenguela deposit to date, which significantly enhances the understanding of the deposit. Approximately 90% of the recent 2024/2025 drilling took place within the limits of the historic resource.
The recent infill drilling converted a significant tonnage from the Inferred category to Measured and Indicated (M&I). Combined M&I resources increased by 11.37 million tonnes or 28.3% to 51.55 million tonnes. The contained metal in M&I resources increased relative to the 2023 MRE* as follows: 1) Silver increased by 21.3 Moz (21%) to 122.5 Moz M&I with 22.0 Moz Inferred resources. 2) Manganese increased to 2.93 Mt M&I with 0.47 Mt Inferred resources. 3) Copper increased to 717.1 Mlb M&I with 118.4 Mlb Inferred resources. 4) Zinc increased to 372.4 Mlb M&I with 80Mlb Inferred resources.
Ralph Rushton, President, said, “The new MRE reflects a significant derisking of the Berenguela resource as the 2024/2025 drilling has successfully defined areas of mineralisation near the margins and confirmed the consistent nature of the resource. The MRE shows a 28% gain in the measured and indicated tonnes, adding to the M&I metal inventory at Berenguela. Mineralization remains open to the east. We were very pleased to also see that the M&I grades for silver, copper and manganese held up well with minimal drop-off as we defined areas of the mineralization near the margins of the resource. This confirms the consistent nature of the mineralization across the length and breadth of the known footprint. Our team is now focused on expediting the development and engineering work at Berenguela. We are also planning additional drilling toward the eastern margins of the mineralization to follow up the high-grade copper intersection seen in AFD 100 which intersected 156m from surface grading 290 g/t silver, 1.12% copper and 7.3% manganese.”
