Aftermath Silver: What Do Berenguela's Latest Drill Results Mean for Investors?

Aftermath Silver Ltd (TSX-V:AAG, OTCQX:AAGFF) recently announced a robust set of Phase 3 drill results from its wholly-owned Berenguela silver-copper-manganese project in Peru, signaling a significant de-risking event for the asset. These initial assays, covering 17 drill holes totaling 1,061.6 meters, have not only confirmed high-grade mineralization but also prompted the company to double its drilling campaign to 90 holes covering 6,000 meters. This expansion underscores management's confidence in the project's potential and its strategic importance.

The headline intercepts are truly impressive, with hole AFD152 returning 48.5 meters grading 438 grams per tonne (g/t) silver, 2.22% copper, and 24.9% manganese from just 26.5 meters downhole. Another standout, hole AFD155, intersected 70 meters at 230 g/t silver, 1.81% copper, and 10.9% manganese from surface. These results are not merely good; they rank among the strongest seen across all three phases of drilling to date, indicating consistent, near-surface, high-grade mineralization that could be amenable to early-stage open-pit mining.

The company's strategy is clear: focus on upgrading lower-confidence resources to higher categories, collect material for metallurgical test work, and conduct infill drilling in areas targeted for potential early mining. The current drilling is primarily concentrated along a 225-meter strike length within the existing resource, specifically aimed at delineating high-grade zones close to surface. This methodical approach is critical for advancing the project towards a preliminary feasibility study (PFS), which is already underway and expected to be completed in 2026.

For investors, these results translate into enhanced project economics and reduced development risk. The consistent association between silver and copper mineralization, coupled with significant manganese, creates a multi-metal revenue stream that diversifies the project's value proposition. With drill recoveries averaging 95% in mineralized zones and intersections generally representing true thickness, the geological confidence in Berenguela continues to strengthen, paving the way for a more robust resource estimate and a compelling investment case.

How Do Berenguela's Multi-Metal Resources Stack Up in the Market?

Berenguela is not just a silver project; it's a polymetallic powerhouse, hosting significant silver, copper, and manganese mineralization within folded limestone sequences. This multi-metal profile is a key differentiator, especially in today's market where demand for critical minerals is surging. The latest drill results reinforce the project's substantial resource base, which, as of November 30, 2025, includes measured resources of 8.49 million tons grading 101 g/t silver, 8.97% manganese, 0.89% copper, and 0.32% zinc.

Combined measured and indicated resources total an impressive 51.55 million tons, with inferred resources adding another 14.33 million tons. The contained metal in the measured and indicated categories alone is estimated at 122.5 million ounces of silver, 2.93 million tons of manganese, 717.1 million pounds of copper, and 372.4 million pounds of zinc. This scale positions Berenguela as a globally significant deposit, particularly for manganese, which accounts for approximately 75% of the mineral resource's relative value, followed by 13% silver and 11% copper.

The strategic importance of manganese cannot be overstated. It's a critical component in steel production and, increasingly, in high-performance lithium-ion batteries for electric vehicles. As the world transitions to a green economy, secure and ethical sources of battery-grade manganese sulphate (MnSO₄) are in high demand. Aftermath Silver is actively assessing potential manganese products, including MnSO₄, which could unlock substantial additional value for the project and position it at the forefront of the battery metals supply chain.

The ongoing metallurgical and engineering work, aimed at optimizing processing flowsheets for silver, copper, and zinc recovery, is crucial for realizing the full economic potential of these diverse metals. The ability to produce multiple high-value commodities from a single deposit provides a strong hedge against price fluctuations in any one metal and enhances the project's overall resilience. Berenguela's multi-metal endowment makes it a compelling asset in the evolving landscape of critical mineral supply.

Why is Copper the New Gold, and What Does This Mean for Aftermath and Midnight Sun?

Copper is rapidly emerging as one of the most strategically vital commodities globally, often dubbed "the new gold" due due to its indispensable role in the energy transition and electrification. The current market dynamics are characterized by a widening supply deficit and robust demand, driven by electric vehicles, renewable energy infrastructure, and smart grid technologies. Analysts project a global refined copper deficit of approximately 330,000 metric tons (kmt) in 2026, a structural imbalance fueled by acute supply disruptions and a sluggish global supply growth rate of just 1.4%.

This severe shortage is pushing copper prices higher, with J.P. Morgan forecasting prices to reach $12,500 per metric ton in Q2 2026, averaging near $12,075 per metric ton for the full year. For context, the current price of copper (HGUSD) is $5.49 per pound, or approximately $12,100 per metric ton. This bullish outlook provides a powerful tailwind for copper-focused developers like Aftermath Silver, with its significant copper component at Berenguela, and particularly for Midnight Sun Mining (TSX-V:MMA, OTCQB:MDNGF), which is defining a large-scale copper discovery at Dumbwa in Zambia.

The geopolitical landscape further amplifies copper's importance. Major economies are locked in a race to secure stable supply chains for critical minerals, aiming to reduce reliance on dominant players. Zambia, with its rich copper deposits, is actively courting global investors as part of a broader strategy to position itself as a key alternative supplier. This heightened competition and strategic interest could significantly elevate the importance and value of projects like Dumbwa as they advance towards potential development.

For investors, this macro environment creates a compelling narrative for companies with significant copper exposure. The recent dip in copper futures, which fell below $5.8 per pound last week due to short-term geopolitical and monetary pressures, should be viewed in the context of this powerful long-term structural demand. This volatility may present a buying opportunity for those betting on the sustained long-term narrative of a widening copper deficit and rising prices, making both Aftermath and Midnight Sun attractive plays in the critical minerals space.

Midnight Sun Mining: Is Dumbwa Zambia's Next Generational Copper Deposit?

Midnight Sun Mining Corp. is rapidly advancing its Dumbwa Project in Zambia, where ongoing drilling continues to define what could become a significant large-scale copper discovery. The project is strategically located in the highly prospective Zambia-Congo Copperbelt, surrounded by producing mines like Lumwana and First Quantum’s Kansanshi Mine, Africa’s largest copper mining complex. This geological neighborhood alone speaks volumes about Dumbwa's potential.

The company's latest update from Vice President Adrian O'Brien highlighted the project's progress, noting that a discovery was made in August 2025, and 166 holes have been drilled to date, with 29 holes having released assays. The drilling has already established a strike length exceeding 3.6 kilometers, with exceptional continuity, and the broader target is a robust 20-kilometer copper-in-soil anomaly—a scale almost unprecedented in Zambia. This systematic delineation in 100 to 200-meter increments along strike has proven highly effective in rapidly revealing the true scale of the system.

Recent assay highlights from January 2026 further underscore this potential. Hole DBW-25-021 intercepted 0.89% copper over 25 meters, with four separate mineralized zones within the hole. Another significant intercept, DBW-25-030, returned 0.46% copper over 50 meters, including a higher-grade section of 1.36% copper over 6 meters. These results, combined with DBW-25-027's 0.48% copper over 21.85 meters, demonstrate consistent, shallow mineralization similar to the nearby Lumwana Mine, strengthening confidence in Dumbwa's potential to host a generational copper deposit.

Zambia itself is making a bold play in the global copper market, aiming to more than triple its copper output to 3 million metric tons by 2031. This ambitious national goal, coupled with increasing geopolitical interest from the U.S. and other major economies seeking to diversify critical mineral supply chains away from Chinese dominance, positions Midnight Sun's Dumbwa project as a key player in this strategic shift. The project's advancement aligns perfectly with Zambia's national strategy and global demand for secure copper supply.

What Are the Investment Implications and Risks for Junior Miners in This Environment?

For investors considering junior miners like Aftermath Silver and Midnight Sun Mining, the current environment presents both significant opportunities and inherent risks. The bullish long-term outlook for critical minerals, particularly copper, silver, and manganese, provides a strong fundamental backdrop. These companies are exploring and developing assets that are essential for the global energy transition, making them attractive to investors seeking exposure to future-proof commodities.

However, junior mining investments are inherently high-risk, high-reward propositions. Exploration success, while exciting, does not guarantee economic viability. Factors such as metallurgical challenges, permitting delays, infrastructure limitations, and fluctuating commodity prices can significantly impact project development. Aftermath Silver is mitigating some of these risks by focusing on a PFS for Berenguela and optimizing processing flowsheets, while Midnight Sun is rapidly de-risking Dumbwa through extensive drilling.

Geopolitical risks are also a consideration, particularly for projects in developing nations. While Zambia is actively courting foreign investment, political stability, regulatory changes, and local community relations can influence project timelines and costs. Similarly, Peru, while a well-established mining jurisdiction, carries its own set of operational and social considerations. Investors must weigh these country-specific risks against the potential rewards of substantial discoveries.

The capital-intensive nature of mining means that these companies will require significant funding to advance their projects from exploration to production. While Aftermath Silver recently completed the acquisition of Berenguela ahead of schedule, demonstrating financial discipline, future capital raises could dilute existing shareholders. Midnight Sun's ability to attract further investment will be crucial as Dumbwa moves from resource delineation to development. Despite these risks, the potential for substantial returns from a major discovery in a strong commodity market remains a powerful draw for speculative capital.

What's the Bull Case for Aftermath Silver and Midnight Sun Mining?

The bull case for Aftermath Silver hinges on Berenguela's multi-metal potential and its advanced stage of development. The project's high-grade silver, copper, and manganese intercepts, particularly near surface, suggest a robust economic profile that could support a low-cost, open-pit operation. The ongoing PFS and metallurgical work are critical catalysts that could unlock significant value by demonstrating the project's technical and economic viability, especially with the rising demand for battery-grade manganese.

For Midnight Sun Mining, the bull case is built on the sheer scale and strategic importance of its Dumbwa copper discovery. A 20-kilometer copper-in-soil anomaly and a rapidly expanding 3.6-kilometer strike length indicate a truly district-scale opportunity in a world hungry for copper. The project's location in the prolific Zambian Copperbelt, coupled with Zambia's ambitious national production targets and increasing geopolitical backing, positions Dumbwa as a potential Tier-1 asset that could attract major mining interest or even a buyout.

Both companies benefit from the overarching macro tailwinds of the critical minerals supercycle. With copper prices projected to climb significantly and demand for silver and manganese steadily increasing, the underlying value of their in-ground resources is poised for appreciation. Successful de-risking through ongoing drilling, positive metallurgical results, and favorable economic studies could lead to substantial re-ratings for both stocks as they transition from pure exploration plays to development stories.

The current market volatility, particularly in copper, might be seen as a temporary dip in a long-term uptrend, offering an attractive entry point for investors with a long-term horizon. As the structural supply deficit for copper becomes more pronounced in 2026 and beyond, projects like Berenguela and Dumbwa, which are positioned to deliver new supply, will become increasingly valuable. Their ability to execute on development plans will be key to capturing this value.

The next 12-24 months will be pivotal for Aftermath Silver and Midnight Sun Mining. Continued drill success, positive economic studies, and strategic partnerships will be key indicators to watch. For investors seeking exposure to the critical minerals boom, these two junior miners offer compelling, albeit speculative, opportunities.
