About Us
Pasto Bueno Tungsten Inc. is a privately held company focused on redeveloping and restarting the historic mine. The company’s objective is to re-establish Pasto Bueno as a modern tungsten producer through disciplined exploration, engineering, and responsible mining practices.
Tungsten is a critical metal used in defense systems, aerospace, energy infrastructure, and advanced manufacturing. With global supply highly concentrated, new sources of high-grade tungsten are increasingly important for secure industrial supply chains.
A Historic Mine with a Strategic Future
Why Pasto Bueno Matters
Proven District: A historic producing district with well-documented mineralization.
Infrastructure: Existing underground development supports future operations.
Community Opportunity: Potential for employment and economic growth in local communities.
Redeveloping One of the World’s Highest-Grade Historic Tungsten Mines
The Pasto Bueno mine, located in the Ancash region of Peru, is one of the most historically significant tungsten-producing districts in the Western Hemisphere. Situated in the northern extension of the Cordillera Blanca, the project benefits from a well-established mining legacy, existing infrastructure, and a highly prospective geological setting.
Pasto Bueno is distinguished by its exceptionally high-grade tungsten mineralization, hosted in steeply dipping quartz veins associated with a quartz monzonite intrusive system. Historically, operations produced ore averaging approximately 0.7–0.8% WO₃, placing it among the highest-grade tungsten mines globally. These grades are materially above most operating tungsten mines worldwide, where lower-grade bulk-tonnage deposits are more common.
