Excelsior Releases Updated Prefeasibility Study; Post-Tax NPV of $829 Million and Initial Capital Costs Reduced by 84% to $45.9 Million

VANCOUVER, BC--(Marketwired - February 09, 2016) - Excelsior Mining Corp. (TSX VENTURE: MIN) (FRANKFURT: 3XS) (OTCQX: EXMGF) ("Excelsior" or the "Company") is pleased to announce the results of a comprehensive Updated Prefeasibility Study ("Updated PFS") on the North Star Deposit of the Gunnison Copper Project, located in Cochise County, southeastern Arizona. The project is designed as a copper in-situ recovery ("ISR") mine using solvent extraction-electrowinning ("SX-EW"). The Updated PFS was completed as a result of the recent acquisition of the Johnson Camp Mine ("JCM") and staged production approach which have dramatically lowered initial capital costs to $45.9 million. Excelsior has also made progress on its permitting process and an update is included below in this news release.

Updated Prefeasibility Study Results

Highlights of the North Star Gunnison Copper Project Updated PFS (United States dollars)

• Net Present Value ("NPV") of $1.2 billion pre-tax and $829 million post-tax
• at 7.5% discount rate using a life of mine ("LOM") copper price of $2.75/lb;
• Internal Rate of Return ("IRR") of 57.9% pre-tax and 45.8% post-tax;
• Initial construction capital costs of $45.9 million
• includes 20% contingency, 16% EPCM, freight, mobile equipment, owner's costs and capital spares;
• Payback period for initial capital of 1.8 years pre-tax and 2.6 years post-tax;
• Average life-of-mine operating costs of $0.70/lb;
• All-In Cost (all capital plus operating costs) of $1.24/lb;
• Sensitivity analysis at a LOM copper price of $2.00/lb generates an IRR of 30.8% pre-tax and 26.2% post-tax.
• Over 850 million pounds of copper added to the probable mineral reserve, an increase of 24%;
• Mine life of 27 years;
• Staged production profile: initial production rate of 25 million pounds of copper cathode per annum using the existing JCM facilities, followed by an intermediate expansion stage to 75 million pounds per annum and final expansion stage to full production of 125 million pounds per annum (includes the construction of an acid plant at full production). The staged production profile makes possible the funding of future expansions out of cash flow;
• Staged production approach lowers initial capital costs, reduces financing risk and speeds the timeline to first production. 

Commenting on the results, President and CEO, Stephen Twyerould said, "This Updated Prefeasibility Study supports the advantages of our recent acquisition of the Johnson Camp Mine. The Company has pre-purchased a 25 million pound per annum SX-EW processing facility that has helped to reduce our overall start-up capital to about $46 million. This is an outstanding result. Even at today's copper prices of $2.00/lb, the Gunnison Copper Project would still return a post-tax IRR of over 26%..."
