Excelsior Mining Provides Mine Construction Progress Report

Phoenix, Arizona–(Newsfile Corp. – January 31, 2019) – Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) (“Excelsior” or the “Company”) is pleased to provide a construction progress report for the Gunnison Copper Project (“Gunnison”), in southeast Arizona. Photos of the construction process can be found on the Company’s website. First copper production is scheduled for Q4 2019.

Construction Highlights:

  • A new access road south of the I10 Highway has been installed. Access to the production wellfield has been improved and overall transport efficiencies have been upgraded. The Gunnison Copper Project remains one of the most easily accessible mining projects in the world; the project benefits from direct access to all critical infrastructure components such as road, rail, power and water.
  • The drilling campaign program is advancing with five drill rigs currently on site. Collar drilling and cement casing of the of the initial wells is on-going in advance of down-hole activities, such as the installation of pumps and instrumentation. Drilling of the entire wellfield, which will consist of approximately 41 production wells and 22 compliance wells, is expected to be completed by July 2019.
  • Construction of the pipeline corridor connecting the processing facilities at the Johnson Camp Mine to the wellfield has commenced. Jack and bore, the method of horizontal drilling that is being employed to install a pipeline under the I10 Highway, is underway. Crews have completed the launch and receiving pits; horizontal boring is scheduled to mobilize in March. The entire two-mile high-density polyethylene (HDPE) pipeline corridor is expected to be completed by May 2019.
  • Staff ramp-up in expectation of production continues; a notable recent hire is Brent Berg, who is the new Environment, Health & Safety (EH&S) Manager. Mr. Berg was the former President of Cameco Resources, one of the largest in-situ uranium mining companies in the United States.

During the construction process, Excelsior will remain committed to our core value of achieving technical and financial excellence, said Chief Operating Officer, Roland Goodgame. “We will continue to make safety our leading priority as the security and wellbeing of our workers is critical to the ultimate success of the project. Our commitment to safety extends to all those within the local communities as we advance the Gunnison Copper Project towards producer status later this year.”
