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

First Mining Finance Corp. ("First Mining" or the "Company") (TSX VENTURE:FF)(OTCQX:FFMGF) is pleased to announce that it has completed its previously announced non-brokered private placement financing of 33,750,000 units ("Units") at a price of $0.80 per unit, raising gross proceeds of $27,000,000 (the "Private Placement").

Each Unit issued under the Private Placement consists of one common share of First Mining and one-half of a common share purchase warrant, with each whole warrant entitling the holder to purchase one additional common share of First Mining at $1.10 for a period of 36 months from the date of closing of the Private Placement.

All securities issued in connection with the Private Placement are subject to a Canadian statutory hold period of four months and one day from the date of closing of the Private Placement. In addition, securities issued to United States accredited investors in connection with the Private Placement are subject to the applicable hold periods required under United States securities laws. As the Private Placement was conducted on a non-brokered basis, no finders' fees were paid by the Company in connection with the Private Placement. Certain directors and officers of the Company subscribed for an aggregate of 1,139,659 Units in the Private Placement.

Keith Neumeyer, Chairman of First Mining, states: "We are very pleased with the incredible level of interest we received in this financing which is yet another milestone in the rapid growth of the Company. With this financing, First Mining is now in a very strong financial position, with cash on hand of approximately $37.3 million. We welcome the new shareholders to our Company, including various institutional shareholders. The addition of capital to the Company allows us to generate internal value from our projects while at the same time allows us to pursue additional accretive acquisitions."

The Company intends to use the proceeds of the Private Placement for potential future property acquisitions, economic studies and resource estimates on the Company's current projects, and for general working capital and corporate purposes.
