Excellon Defines Targets at Tres Cerros; Grab Sampling Returns up to 14 g/t Gold and 9,050 g/t Silver

NewsfileAug 31, 2026 · 5 days agoEXN

Analyst Takeaways

Grab samples returning up to 14 g/t gold represent high-grade mineralization at Tres Cerros, significantly above typical open-pit thresholds and comparable to underground operation economics.
Silver values reaching 9,050 g/t (approximately 291 oz/t) suggest a polymetallic system with substantial precious metals endowment that could enhance project economics.
The 11,000-hectare Tres Cerros property's adjacency to the operating Mallay Mine provides immediate infrastructure advantages and reduces exploration and development risk.
Early-stage grab sampling and district-scale mapping are defining exploration targets, indicating the company is in preliminary stages before drilling commences.
Success at Tres Cerros could establish a second mineralized center within Excellon's existing operational footprint, supporting long-term resource growth and production optionality.

Frequently Asked Questions

How significant are the gold and silver grades reported at Tres Cerros?+

The 14 g/t gold samples are considered high-grade for underground operations and significantly exceed typical open-pit thresholds, while 9,050 g/t silver (291 oz/t) indicates strong polymetallic potential. These grab sample results are preliminary but encouraging for target definition.

What is the relationship between Tres Cerros and Excellon's Mallay Mine?+

Tres Cerros is an adjacent exploration property covering 11,000 hectares near the operating Mallay Mine, offering potential synergies with existing infrastructure, processing facilities, and operational expertise while reducing development risk.

What is the current exploration stage at Tres Cerros?+

The company is conducting district-scale geologic mapping and grab sampling to define exploration targets; this early-stage work precedes drilling programs and indicates exploration is in the target generation phase.

Could Tres Cerros mineralization extend into an operating mine scenario?+

While grab samples show high-grade potential, Tres Cerros remains in the exploration phase; proximity to Mallay Mine infrastructure suggests favorable conditions for future development if drilling confirms continuity and resource size.
