Excelsior Mining Corp. (TSX-V: MIN) (Frankfurt: 3XS) (OTCQX: EXMGF) ("Excelsior" or the “Company”)is pleased to announce that the Company has entered into a subscription agreement for a financing, with an affiliate of Greenstone Resources L.P. (“Greenstone”), for total gross proceeds of US$14.0 million. The financing consists of a private placement of common shares (the “Private Placement”) at CDN$0.45 per share for gross proceeds of US$10.0 million and the sale of a 1% gross revenue royalty on the Gunnison Copper Project (the “Royalty Financing”) for gross proceeds of US$4.0 million. Upon closing, Excelsior would be fully funded through to a decision to construct and the expected completion of the permitting process. Receipt of final operating permits is expected in Q2, 2017. Construction is scheduled to begin in Q3 of 2017, with commercial production anticipated in 2018.

The Private Placement and Royalty Financing require shareholder approval under the rules and policies of the TSX Venture Exchange and applicable Canadian securities laws. The Company intends to obtain shareholder approval for the Private Placement and Royalty Financing at the Annual General Meeting of shareholders that is scheduled to occur on October 27, 2016 in Vancouver, B.C. (the “Meeting”). Assuming shareholder approval is obtained and other conditions precedent to the Private Placement and Royalty Financing are met, then the Private Placement and the Royalty Financing are scheduled to close shortly after the Meeting.

Pursuant to the Private Placement, Greenstone will purchase, by way of a treasury offering, common shares of Excelsior at a price of CDN$0.45 per common share for total gross proceeds of US$10.0 million. Settlement will occur in United States dollars and the exact number of common shares issued has been determined based on a CDN$/US$ exchange rate of CDN$1.00 being equal to US$0.77 (the “Exchange Rate”). Based on the Exchange Rate, upon closing of the Private Placement, Greenstone will acquire 28,860,028 common shares (representing approximately 20.8% of Excelsior’s current issued and outstanding common shares). Greenstone currently holds 55,550,869 common shares of Excelsior (representing 40.11% of the Company’s current issued and outstanding common shares).  After the closing of the Private Placement, Greenstone will hold a total of 84,410,897 common shares, which will represent approximately 50.4% of Excelsior’s issued and outstanding common shares (post-closing of the Private Placement). Greenstone has agreed that it will not, for a period of four months, dispose of the common shares it acquires pursuant to the Private Placement. Upon the closing of the Royalty Financing and after taking into consideration Greenstone’s existing 2% gross revenue royalty, Greenstone will own a 3% gross revenue royalty on the Gunnison Copper Project.

Stephen Twyerould, President & CEO, said, “Our ability to secure a non-dilutive royalty financing in combination with a common share equity placement priced at a premium to the current share price, and all within the context of a bottoming copper price, is another major endorsement of the Gunnison Copper Project. With all the required funding in place to see us through to the projected completion of the permitting process, we have dramatically de-risked our project and helped ensure that we will remain on schedule for production of copper cathode in 2018. Greenstone Resources is one of the most technically astute resource funds operating in the financial markets today; their continued financial support validates our industry-leading project economics and the ability of our management team to execute.”

Pursuant to Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"), each of the Private Placement and Royalty Financing constitutes a "related party transaction" as Greenstone is a related party of the Company. The Company is relying on an exemption from the formal valuation requirement of MI 61-101, based on the fact that the securities of the Company are only listed on the TSX Venture Exchange.  However, the Company will be required to obtain minority shareholder approval for the Private Placement and Royalty Financing as there are no available exemptions. The Company intends to obtain such minority shareholder approval at the Meeting. The common shares that will be acquired by Greenstone will be acquired pursuant to an exemption from the prospectus requirement in section 2.3 of National Instrument 45-106.

The directors of Excelsior who hold shares of the Corporation will enter into irrevocable undertakings pursuant to which they have agreed that they will vote their shares in favour of the Private Placement and Royalty Financing at the Meeting.

The net proceeds of the Private Placement and the Royalty Financing will be used for the continued development of the company's Gunnison Copper Project, including; completion of permitting and the feasibility study, care & maintenance and deferred acquisition costs associated with the Johnson Camp Mine, and for working capital and general corporate purposes.

The Private Placement and Royalty Financing are subject to a number of conditions, including, without limitation, the execution of definitive documentation, receipt of all regulatory approvals, including the approval of the TSX Venture Exchange and the applicable securities regulatory authorities. The Private Placement and Royalty financing are also subject to the receipt of minority shareholder approval.

The securities being offered hereby have not been, nor will they be, registered under the United States Securities Act of 1933, as amended, and may not be offered or sold in the United States or to, or for the account or benefit of, U.S. persons absent registration or an applicable exemption from the registration requirements. This press release shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in any state or province in which such offer, solicitation or sale would be unlawful.
