Aftermath expands Berenguela M&I resource by 28% after successful infill drilling

from Proactive - Interviews for investors · host Proactive Investors

Aftermath Silver CEO Ralph Rushton joined Steve Darling from Proactive to release an updated Mineral Resource Estimate (MRE) for its Berenguela project in southern Peru, confirming and significantly expanding upon its previous 2023 Mineral Resources. The new estimate is based on the most comprehensive geological model of the Berenguela deposit compiled to date, materially enhancing the overall understanding of the scale, structure, and metal distribution of the deposit. Notably, approximately 90% of the company’s recent 2024/2025 drilling program was conducted within the boundaries of the historic resource, allowing for meaningful resource upgrades rather than purely exploratory growth. The recent infill drilling campaign successfully converted a substantial portion of the resource from the Inferred category to the higher-confidence Measured and Indicated (M&I) category. As a result, combined M&I resources increased by 11.37 million tonnes, or 28.3%, bringing the total to 51.55 million tonnes. This upgrade materially strengthens the project’s development profile by reducing geological risk and improving the reliability of future mine planning and economic studies. Contained metal within the M&I category has also increased significantly compared with the 2023 Mineral Resource Estimate. Silver resources rose by 21.3 million ounces, a 21% increase, bringing total M&I silver to 122.5 million ounces, with an additional 22.0 million ounces remaining in the Inferred category. Manganese M&I resources increased to 2.93 million tonnes, with a further 0.47 million tonnes classified as Inferred. Copper M&I resources climbed to 717.1 million pounds, supported by 118.4 million pounds of Inferred copper, while zinc M&I resources reached 372.4 million pounds, along with 80 million pounds in the Inferred category. The upgrade from Inferred to M&I resulted in a corresponding decrease of 7.96 million tonnes in the total Inferred resource inventory, reflecting the improved confidence in the geological model and data density across the deposit. The updated MRE is underpinned by a robust geological database that incorporates results from 439 drill holes. This includes 82 diamond drill holes totaling 5,329 metres completed by Aftermath during the 2024/2025 drilling campaign. In total, 44,842 metres of drilling have now been completed at Berenguela, comprising 20,346 metres of diamond drilling and 24,496 metres of reverse circulation (RC) drilling. The previous resource estimate, documented in the NI 43-101 technical report titled “Berenguela Mineral Resource Estimate NI 43-101 Aftermath Silver Ltd., Province of Lampa, Department of Puno, Peru,” was prepared by AMC Mining Consultants (Canada) Ltd. and carried an effective date of March 30, 2023. The new estimate builds directly on this foundation with significantly higher data density and geological confidence. #proactiveinvestors #aftermathsilverltd #tsxv #aag #otcqx #aagff #mining #SilverMining, #BerenguelaProject, #Mining #Silver #Copper #Manganese #Peru #DrillingResults #BatteryMetals #ResourceModel #Investing
