Excelsior Concludes Successful Metallurgical Drill Program at Gunnison Copper Project in Arizona

Excelsior Mining Corp. is pleased to announce that the metallurgical drill program has ended successfully at the Gunnison Copper Project in Arizona.

Ten (10) 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, Arizona under the supervision of Dr. Ronald J. Roman, an independent consultant who is a Qualified Person as defined by NI 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.
