Excelsior Mining Corp. provided 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 fourth quarter of 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 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; and 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 larger in-situ uranium mining companies in the United States.
