Excelsior Mining Corp (2) (TSX-V:MIN) Shares Issued 114,801,562 Last Close 11/4/2014 $0.24 Wednesday November 05 2014 - News Release Mr. Mark Morabito reports EXCELSIOR MINING CORP.: SUCCESSFUL METALLURGICAL DRILL PROGRAM CONCLUDES AT GUNNISON Excelsior Mining Corp.'s metallurgical drill program has ended successfully at the Gunnison copper project
in Arizona. Ten diamond drill holes were completed totalling 5,899 feet of diamond drilling (11,306 feet in total
drilling). Excelsior has submitted a total of 23 samples for metallurgical testing. The samples will
be crushed and categorized by geologic factors; the tests are estimated to last 120 to 160 days based
on separate leach cycles. Open-cycle column leaching will include mature raffinate generated in previous
column leach tests on ore from the North Star deposit or from the Johnson camp mine which is adjacent
to the North Star deposit. Testing will be conducted by the independent laboratory, MAG (Minerals Advisory
Group) of Tucson, Ariz., under the supervision of Dr. Ronald J. Roman, an independent consultant, who
is a qualified person as defined by National Instrument 43-101. Additional box leach and separate acid
consumption tests will also be completed as part of the overall metallurgical program. The results of these metallurgical tests will be used to determine copper extraction rates, acid consumption
rates, and rinsing procedures and rates. Results will be used for both the permitting application process
and the feasibility study. For further information please see the company's previous news release dated Sept. 15, 2014, "Excelsior
Provides Details on Metallurgical Drill Program." Commenting on this news, president and chief executive officer, Stephen Twyerould, stated: "Each metallurgical
sample can weigh as much as 350 pounds; these are robust samples from which we will be able to gather
feasibility-level data for the critical components that will drive our project: namely acid consumption
and copper recovery rates. We fully expect that the results of this comprehensive metallurgical program
will continue to support the potential for industry leading economics combined with environmental excellence." Dr. Stephen Twyerould, fellow of AusIMM, president and chief executive officer of Excelsior, and a qualified
person as defined by National Instrument 43-101, has reviewed and approved the technical information
disclosed in this news release. We seek Safe Harbor.
