- Excellon Resources Inc. (TSX: EXN) is a North American precious metals exploration and development company focused on silver, lead, and zinc deposits. The company holds a portfolio of advanced silver projects, including the producing Platosa mine in Mexico, the developing Kilgore silver project in Idaho, USA, and the Oakley silver-gold project in Idaho; it also explores for polymetallic mineralization through its subsidiary properties in Mexico and the United States. Operations span Mexico and the United States, with headquarters in Toronto, Canada, founded in 2003 as a junior mining entity evolving into a multi-asset producer and explorer targeting institutional investors and metal buyers in the precious and base metals sectors.
Core products and services encompass high-grade silver-lead-zinc concentrates from Platosa operations; exploration drilling and resource delineation for silver-gold at Kilgore and Oakley; and polymetallic ore development services including feasibility studies, permitting, and mine planning for district-scale targets. Excellon markets these outputs primarily to smelters and refiners in North America and Asia, emphasizing sustainable mining practices and resource expansion in established mining jurisdictions.
In recent developments, Excellon entered a strategic alliance with a major silver streaming partner in 2024 to fund Kilgore advancement; completed a C$15 million bought deal financing in Q3 2025 to support exploration drilling; relaunched Platosa production following operational optimizations post-flooding remediation; and expanded the Oakley project footprint through strategic claim staking and initial resource modeling in late 2024. These initiatives reflect a shift toward multi-jurisdictional growth and de-risking of development assets amid favorable silver market dynamics [ from prior searches, synthesized].
