Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) ("E xcelsior" or the “Company”)
is pleased to provide a construction progress report for the Gu nnison Copper Project (“Gunnison”), in
southeast Arizona. Photos of the construction process can be fo und 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 rig s currently on site. Collar drilling and
cement casing of the of the initial wells is on-going in advanc e 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 processin g 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 t o 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 notabl e 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.”
