NEWS RELEASE
Excelsior Mining Completes Pipeline Corridor from Wellfield to Production Facility
August 27, 2019
Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) ("E xcelsior" or the “Company”)
confirms the successful completion of the pipeline corridor at the Gunnison Copper Project in southern
Arizona. Construction of a two-mile high-density polyethylene (HDPE) pip eline corridor connecting the
Johnson Camp Mine (JCM) processing facility to the production wellfield began in January and has now
been successfully completed precisely as per Excelsior’s constr uction timeline. Excelsior remains on-
schedule for first copper production in Q4 2019.
“Another critical construction milestone has been successfully completed;” commented Stephen
Twyerould, CEO & President, “We are now more than 90% finished in terms of the entire construction
process, and we look forward to completing the remaining elements over the next month.”
Construction of the pipeline corridor included the installation of a bridge over an area of the property
where elevation is required, and a 460-foot tunnel under the I-10 highway. The pipeline corridor contains
18" and 20” diameter PLS and raffinate lines, as well as a freshwater line and a utility line.
Excelsior’s North Star deposit contains a measured and indicated copper resource of 4.99 billion pounds
(873 million tons grading 0.29%). The North Star deposit is located immediately adjacent to JCM, which
Excelsior purchased out of receivership in 2015 for $8.4 millio n (see Excelsior news release dated
October 8, 2015).
