VANCOUVER, BC, Aug. 17, 2020 /CNW/ - First Mining Gold Corp. ("First Mining" or the "Company") (TSX: FF) (OTCQX: FFMGF) (FRANKFURT: FMG) is pleased to announce that it has entered into an agreement with Cormark Securities Inc., as lead underwriter, on behalf of a syndicate of underwriters (collectively, the "Underwriters"), pursuant to which the Underwriters have agreed to purchase, on a bought deal basis, 40,000,000 units of the Company (the "Units") at a price of $0.50 per Unit (the "Offering Price") for gross proceeds to the Company of approximately $20 million (the "Offering").

Each Unit will consist of one common share in the capital of the Company (each a "Common Share") and one-half of one common share purchase warrant (each whole warrant, a "Warrant"). Each Warrant will entitle the holder to acquire one additional Common Share at a price of $0.70 for a period of 24 months following the closing of the Offering.

The Company has also granted the Underwriters an option (the "Over-Allotment Option") to sell up to an additional 6,000,000 Units at the Offering Price for additional gross proceeds of up to $3 million. The Over-Allotment Option shall be exercisable in whole or in part at any time prior to the date that is 30 days after the closing of the Offering, to cover over-allotments, if any, and for market stabilization purposes. In the event that the Over-Allotment Option is exercised in full, the aggregate gross proceeds of the Offering to First Mining will be approximately $23 million.

The Company intends to use the net proceeds of the Offering for exploration, development and permitting activities at its Canadian gold projects, potential acquisitions, as well as for working capital and general corporate purposes.

The Units will be offered by way of a prospectus supplement (the "Prospectus Supplement") to the Company's base shelf prospectus dated June 24, 2019. The Prospectus Supplement will be filed in all of the provinces of Canada other than Québec and, together with the related Base Shelf Prospectus, will be available on SEDAR at www.sedar.com.

The Offering is scheduled to close on or before August 26, 2020 and is subject to certain conditions including, but not limited to, receipt of all regulatory approvals, including the approval of the Toronto Stock Exchange.

The securities offered in the Offering have not been, and will not be, registered under the U.S. Securities Act or any U.S. state securities laws, and may not be offered or sold in the United States or to, or for the account or benefit of, United States persons absent registration or any applicable exemption from the registration requirements of the U.S. Securities Act and applicable U.S. state securities laws.

Cautionary Note to United States Investors

This news release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all resource and reserve estimates included in this news release have been prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy, and Petroleum 2014 Definition Standards on Mineral Resources and Mineral Reserves. NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the SEC, and mineral resource and reserve information contained herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, the term "resource" does not equate to the term "reserves". Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. The SEC's disclosure standards normally do not permit the inclusion of information concerning "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" or other descriptions of the amount of mineralization in mineral deposits that do not constitute "reserves" by U.S. standards in documents filed with the SEC. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. U.S. investors should also understand that "inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an "inferred mineral resource" will ever be upgraded to a higher category. Under Canadian rules, estimated "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies except in rare cases. Investors are cautioned not to assume that all or any part of an "inferred mineral resource" exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in-place tonnage and grade without reference to unit measures. The requirements of NI 43-101 for identification of "reserves" are also not the same as those of the SEC, and reserves reported by the Company in compliance with NI 43-101 may not qualify as "reserves" under SEC standards. Accordingly, information concerning mineral deposits set forth herein may not be comparable with information made public by companies that report in accordance with U.S. standards.
