Excelsior Mining Corp. (TSX: MIN) (OTCQB: EXMGF) (FSE: 3XS) (“Excelsior” or the “Company”) is pleased to announce that it has received all permits to commence operations at the Johnson Camp Mine (“JCM”) in southeast Arizona, which will produce Made in America copper expected to be used domestically to strengthen American supply chains. First copper production is anticipated in H1 of 2025.

Excelsior received the amended Mined Land Reclamation Plan (MLRP) approval from the State of Arizona. The MLRP, along with the recently approved Air Quality Permit (AQP) and the Aquifer Protection Permit (APP), means that all approvals needed to start the production of copper at JCM have been received.

“This final permit is a key milestone bringing us one step closer to copper production at JCM. We believe the partnership with Nuton LLC for the first industrial-scale deployment of their sulfide leaching technology, combined with the oxide ore production, generates an exciting opportunity for both organizations and the wider copper industry,” comments Robert Winton, Senior Vice President Operation & GM of Excelsior Mining. He adds, “Excelsior’s local and state engagement continues to deliver opportunity in Southeastern Arizona.”
