Excelsior Advances Permitting Process

VANCOUVER, BC–(Marketwired – April 26, 2016) –  Excelsior Mining Corp. (TSX VENTURE: MIN) (FRANKFURT: 3XS) (OTCQX: EXMGF) (“Excelsior” or the “Company”) is pleased to announce an update on the permitting progress at the Gunnison Copper Project.

Administrative Completeness Review (ACR) (“Administrative Review”) has been achieved for both the Federal Underground Injection Control (UIC) Permit and for the State Aquifer Protection Permit (APP). The UIC is issued by the Environmental Protection Agency (EPA) under the Safe Drinking Water Act; whereas the APP is issued by the Arizona Department of Environmental Quality (ADEQ) under the Environmental Quality Act. Administrative Review is the first stage of the permitting process. It confirms that the permitting application is administratively complete, meaning that all the required documentation and technical data are present. Excelsior is working closely with the State and Federal regulatory agencies to help advance the issuance of draft permits, which Excelsior expects will occur early next year. Excelsior has now entered the technical review component of the permitting process.

Excelsior is also pleased to announce that both the Air Quality Permit and the Aquifer Protection Permit for Johnson Camp have been successfully amended and transferred from the prior owner to Excelsior Mining JCM, Inc. Both of these permits were issued by the ADEQ, and Excelsior considers this efficient transfer to be demonstrative of the proficiency of the permitting process in Arizona.

Commenting on this progress, Stephen Twyerould, President and CEO, said, “With the successful completion of Administrative Review, the permitting process at Gunnison has moved beyond the first key milestone. We look forward to continuing our work with the respective agencies as we undertake technical review. Excelsior has every confidence in the efficacy of the agencies to deliver workable permits, in a timely manner, which ensure safe operations and the protection of the environment.”
