Current work (Q1 2026) at Berenguela is focused engineering studies for Berenguela looking at potential production of silver, copper and a battery grade manganese product. Work is on going to generate samples of high purity manganese sulphate monohydrate (HPMSM) which could be a potentially important co-product to accompany future production of silver and copper. Results of the metallurgical test work will be incorporated into the design of a processing facility in the on going engineering studies.
An updated, current Mineral Resource Estimate was published in late 2025, confirming and expanding Aftermath’s previous 2023 Mineral Resource. Approximately 90% of the recent 2024/2025 drilling took place within the limits of the historic resource.
Aftermath's Phase 3 driling is underway (December 2025). The current drill program has 4 objectives:
- To explore untested areas in the east and south-east zone of the known mineralisation where the 2024-2025 drill campaign and historic drilling encountered high copper grades. This includes the ‘Copper East’ target, identified in 2024/25 which returned longest copper intercept drilled to date at 156m grading 1.12% Cu, 290 g/t Ag and 7.3% Mn, and the highest silver intercept to date at 1.95m @ 14,252 g/t (1.43% Ag) from 29.30 to 31.25m (news release dated Feb 27, 2025)
- To upgrade part of the indicated resources to measured resources primarily in the western and central domains where future mining is likely to initiate;
- To further define the mineralization between the central and northern areas;
- Collection of a bulk sample of mineralization by RC drilling for future metallurgical testwork.
