Schedule of BacTech Activities in Spain

“Spain is one of Europe’s most important mining jurisdictions, and its legacy tailings represent both an environmental challenge and an untapped resource,” said Ross Orr, President and CEO of BacTech. “Being invited to participate alongside the Canadian Embassy and the Spanish government, and having Paul present twice at MMH, gives us an excellent platform to introduce our bioleaching and Zero-Tailings™ technologies to operators, policymakers and potential partners across the Iberian Peninsula.”

Delegates attending MMH 2026 are invited to attend Dr. Miller’s sessions and to connect with the BacTech team at our booth.
