The Canadian mining landscape is currently witnessing a concerted push for operational excellence and resource expansion by Aftermath Silver Ltd. In a recent corporate update, the company reaffirmed its commitment to advancing its two core assets—the Berenguela project in the Puno region of Peru and the Challacollo project in Chile. By maintaining a rigorous timeline for its Pre-Feasibility Study (PFS) in Peru while simultaneously scaling up exploration efforts in Chile, Aftermath Silver is positioning itself as a pivotal player in the regional precious and base metals market.
Main Facts: A Dual-Track Strategy
Aftermath Silver is currently navigating a sophisticated, dual-track development strategy. The company has confirmed that the PFS for the Berenguela project remains firmly on track for delivery in the first quarter of 2027. This milestone is critical, as it serves as the foundation for future development and permitting.
Simultaneously, across the border in Chile, the company is demonstrating high confidence in the Challacollo silver-gold project. Following the successful completion of an initial five-hole drilling campaign, management has greenlit an expansion of the exploration program. This dual focus highlights the company’s ability to manage technical engineering milestones in Peru while aggressive "boots-on-the-ground" exploration continues in the Chilean Andes.
Chronology of Development
The current progress at Berenguela is the result of a systematic timeline that began in early 2026. The milestones achieved to date include:
- February 2026: Formal commencement of the Pre-Feasibility Study (PFS).
- Mid-2026 (July): Completion of a 4,002-meter diamond drilling campaign, the third in the project’s recent history, aimed at refining the geological model.
- Late 2026/Early 2027: Execution of gap analyses covering metallurgical, geotechnical, and environmental data. The integration of these datasets is currently finalizing the technical framework for the upcoming PFS.
- Ongoing (2027): Deployment of a secondary drill rig to expedite the exploration of the "Copper East" and "South-West Intrusive" zones, ensuring that resource expansion happens in tandem with project engineering.
In Chile, the timeline for Challacollo has been similarly rapid. After the initial 630-meter drill program confirmed geological continuity in the Lolon and Lucy veins, the board moved quickly to authorize an expansion to 2,000 meters to further define the resource footprint.
Supporting Data and Technical Insights
The technical strength of the Berenguela project is rooted in its diverse mineralogical profile, which includes significant copper, silver, and manganese potential.

The Copper East Opportunity
The "Copper East" zone has emerged as a focal point for the company’s exploration team. Previous drilling results from this area have been nothing short of transformative for the project’s valuation. Specifically, the company recorded an intercept of 156 meters grading 1.12% copper, 290 g/t silver, and 7.3% manganese. Perhaps even more striking was the high-grade silver intercept, which yielded 1.95 meters at 14,252 g/t. These numbers demonstrate the high-grade potential that remains open at depth and along strike, suggesting that the current resource estimate may be significantly understated.
Engineering and Metallurgical Optimization
The PFS process has been exhaustive. To ensure the viability of the project, Aftermath Silver has conducted:
- Flowsheet Validation: Enhanced testing to confirm that the metallurgical recovery processes for copper and silver are optimized for the complex ore found at Berenguela.
- Infrastructure Planning: Trade-off studies concerning the optimal placement of processing plants, reagent sourcing, and the integration of sustainable infrastructure to support long-term operations.
- Resource Classification: The drilling program is specifically designed to upgrade current "Indicated" resources to the "Measured" category, providing the high level of confidence required for a bankable feasibility study.
Challacollo’s Expanding Potential
In Chile, the five completed drill holes have validated the structural integrity of the Lolon and Lucy veins. By focusing on the southern extension of the Lolon vein, Aftermath Silver is targeting a high-probability zone for resource growth. The expansion to 2,000 meters is intended to test the limits of this mineralization, potentially increasing the total mineable ounces of silver and gold.
Official Responses and Corporate Outlook
Ralph Rushton, President and CEO of Aftermath Silver, emphasized the company’s disciplined approach to capital allocation and project management. Regarding the Berenguela PFS, Rushton stated: "The pre-feasibility study for the Berenguela project is proceeding exactly as scheduled and remains within our established budget."
This sentiment reflects the company’s broader corporate philosophy: ensuring that technical rigor is never sacrificed for speed. By maintaining a balance between the "PFS-ready" status of Berenguela and the "Exploration-led" status of Challacollo, the company is mitigating risk while maximizing the upside potential for its shareholders. The addition of a second drill rig at Berenguela is a testament to the company’s internal belief that the project’s geological limits have not yet been reached.
Implications for the Market
The implications of these developments are threefold:

- Strategic Asset Value: By securing 100% ownership of both Berenguela and Challacollo, Aftermath Silver maintains complete control over its development timeline and operational strategy. In a market where mid-tier miners are often seeking high-quality, long-life assets, Aftermath’s portfolio is becoming increasingly attractive.
- Regional Synergy: Operating in both Peru and Chile—two of the world’s most mining-friendly and resource-rich jurisdictions—positions the company to leverage local expertise and supply chains. Both regions provide the necessary infrastructure and regulatory clarity to advance projects from discovery to production.
- Commodity Exposure: With a heavy focus on copper and silver, Aftermath Silver is perfectly aligned with the global energy transition. Copper is essential for electrification and green technologies, while silver remains a critical industrial metal with increasing demand in the solar and electronics sectors.
Future Outlook
As the company moves through 2027, the market will be looking closely for the release of the PFS results for Berenguela. If the study confirms the technical and economic viability suggested by current drilling data, it will likely serve as a major catalyst for the company’s market valuation.
Meanwhile, the exploration results from Challacollo will serve as a bellwether for the project’s long-term scale. Should the 2,000-meter expansion program yield positive results, the company may look to initiate its own pre-feasibility or preliminary economic assessment (PEA) for the Chilean asset, further diversifying its risk and revenue streams.
Ultimately, Aftermath Silver is demonstrating a mature, professional approach to project development. By combining advanced engineering studies in Peru with aggressive, data-driven exploration in Chile, the company is building a foundation that is as robust as the geology it explores. Investors and stakeholders alike can expect a steady flow of updates as these two projects continue to evolve toward their respective production goals.
