Excelsior Closes Johnson Camp Mine Acquisition and US$12.0 Million Financing

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec. 15, 2015) -

NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Excelsior Mining Corp. (TSX VENTURE:MIN)(FRANKFURT:3XS)(OTCQX:EXMGF) ("Excelsior" or the "Company") is pleased to announce that it, through a wholly-owned Arizona subsidiary, has closed the acquisition of all of the assets of Nord Resources Corporation, as they relate to the Johnson Camp Copper Mine (the "Johnson Camp Transaction"). The Johnson Camp Copper Mine ("JCM") is located immediately adjacent to Excelsior's Gunnison Copper Project in southeastern Arizona (the "Gunnison Project"). The Company also announces that it has closed concurrent financings of US$12.0 million. For details of the Johnson Camp Transaction, please see Excelsior's news release dated October 8, 2015 - Excelsior to Purchase Johnson Camp Mine and Raise US$12 Million.

Commenting on the closing of the Johnson Camp Transaction, Stephen Twyerould, President and CEO of the Company, said, "The acquisition of the production facilities at Johnson Camp Mine puts Excelsior in an excellent position and represents the delivery of yet another impressive milestone. We remain absolutely confident in our ability to successfully process copper solutions through the existing SX-EW plant, which is expected to significantly reduce both our initial capital requirements and the time required for the start-up of the Gunnison Copper Project. Based on this acquisition, Excelsior intends to provide an updated prefeasibility study in Q1 of 2016, and the feasibility study is scheduled to be completely before the end of 2016."

Concurrent Financing

Excelsior has also closed concurrent financings with an affiliate of Greenstone Resources L.P. ("Greenstone"), for total gross proceeds of US$12.0 million. The financings consists of a private placement of common shares (the "Private Placement") for gross proceeds of US$4 million over two tranches and the sale of 2% gross revenue royalty on the Gunnison Copper Project (the "Royalty Financing") for gross proceeds of US$8 million.

Stephen Twyerould added, "Our ability to complete a significant and largely non-dilutive financing in one of the most challenging environments for junior mining companies is a testament to the quality of the Gunnison Copper Project and our management team. Following upon an exhaustive review of the data from our feasibility work programs, the Greenstone financing represents a major endorsement and allows for the project to maintain its pace and momentum as we head into 2016."

With respect to the Private Placement, on November 30, 2015 the Company closed the first tranche of the Private Placement ("Tranche 1") through the issuance of 8,655,510 common shares to Greenstone for total gross proceeds of US$1.5 million. Please see Excelsior's news release dated December 1, 2015 - Excelsior Announces Closing of First Tranche of Greenstone Financing.

The Company has now closed the second tranche of the Private Placement ("Tranche 2") pursuant to which Greenstone has purchased, by way of a treasury offering, common shares of Excelsior at a price of Cdn$0.23 per common share for total gross proceeds of US$2.5 million. Settlement occurred in United States dollars and the exact number of common shares issued has been determined based on a Cdn$/US$ exchange rate of Cdn$1.00 being equal to US$0.7533 (the "Exchange Rate"). The Exchange Rate was determined using the average of the noon Cdn$/US$ exchange rate, as reported by the Bank of Canada, for the 10 days prior to the execution of the term sheet. Greenstone has acquired 14,425,852 common shares, which represent approximately 10.42% of Excelsior's issued and outstanding common shares.

As result of the closing of Tranche 1 and Tranche 2 of the Private Placement, Greenstone now holds a total of 55,550,869 common shares, which represents approximately 40.14% of Excelsior's issued and outstanding common shares. The common shares issued to Greenstone pursuant to Tranche 2 are subject to a statutory four month hold period expiring on April 15, 2016. In addition Greenstone has agreed that it will not, for a period of one year, dispose of the common shares it acquired pursuant to the Private Placement.

The net proceeds of the Private Placement and Royalty Financing will be used for the consideration payable in the Johnson Camp Transaction, the continued development of the company's Gunnison Copper Project and for working capital and general corporate purposes.
