Aftermath Silver CEO Ralph Rushton joined Steve Darling from Proactive to announce the commencement of a Pre-Feasibility Study (PFS) for the company’s Berenguela silver-copper-manganese project in southern Peru, marking a significant milestone as the company advances the asset toward a potential production decision.

Rushton told Proactive that the move to initiate a PFS follows the successful completion of a C$20 million equity financing and an extensive 82-hole infill drilling program carried out in 2025. The drill campaign intersected mineralization in 95% of the holes, substantially increasing geological confidence across the project.

The resulting updated Mineral Resource Estimate materially strengthened the company’s understanding of the deposit, confirming robust silver and copper mineralization across key zones and supporting the decision to progress Berenguela to the next stage of development. The PFS will build on this improved geological model and is expected to outline updated project economics, mine planning parameters, and development scenarios.

Berenguela currently hosts Measured and Indicated Resources of approximately 122.5 million ounces of silver and 717.1 million pounds of copper, positioning it as a significant polymetallic development asset in the region.

While advancing the PFS, Aftermath Silver plans to maintain exploration momentum across its portfolio. The company will continue drilling key exploration targets at Berenguela, as well as at its Challacollo silver project in Chile, as it seeks to expand resources and unlock additional value.

Rushton emphasized that the initiation of the PFS represents a pivotal step in transforming Berenguela from an advanced exploration asset into a potential future mining operation, while ongoing exploration efforts aim to further enhance the company’s growth pipeline.
