TORONTO--(BUSINESS WIRE)-- Generation Mining Limited (TSX:GENM)(OTCQB: GENMF) ("Generation Mining" or the "Company") is pleased to announce that it has completed its previously announced private placement of $10 million of units of the Company (the “Units”) including the full exercise of the Underwriters’ (as defined below) option, for aggregate gross proceeds of approximately $11.5 million (the “Offering”). The Offering was conducted by a syndicate of underwriters led by Stifel Nicolaus Canada Inc., and including Haywood Securities Inc. (collectively, the “Underwriters”), and consisted of the sale of 31,082,200 Units at a price of $0.37 per Unit.

Each Unit comprised of one common share in the capital of the Company (each a “Common Share”) and one-half (½) of one common share purchase warrant of the Company (each whole warrant, a “Warrant”). Each Warrant entitles the holder thereof to acquire one Common Share at a price of $0.48 at any time from August 24, 2025 until August 24, 2028.

The Company intends to use the net proceeds from the Offering on the development of its Marathon Project and for general corporate purposes.

The Units were issued pursuant to Part 5A of National Instrument 45-106 – Prospectus Exemptions, as amended by Coordinated Blanket Order 45-935 – Exemptions from Certain Conditions of the Listed Issuer Financing Exemptions, to purchasers resident in Canada (other than the province of Québec) and in other qualifying jurisdictions outside of Canada on a private placement basis pursuant to relevant prospectus or registration exemptions in accordance with applicable laws, and are not subject to a statutory hold period pursuant to applicable Canadian securities laws. The Offering remains subject to the final approval of the Toronto Stock Exchange.

The Company also announces that Mr. Eric Sprott, through 2176423 Ontario Inc., a corporation beneficially owned by him, acquired Units in the Offering to maintain his pro rata ownership interest in the Company.

In connection with the Offering, Jamie Levy, the President, Chief Executive Officer and a director of the Company, acquired 189,190 Units, Phillip C.

The Company was exempt from the requirements to obtain a formal valuation or minority shareholder approval in connection with the Insiders’ participation in the Offering pursuant to sections 5.5(a) and 5.7(1)(a) of MI 61-101. The Company did not file a material change report less than 21 days in advance of the closing of the Offering as the participation of the Insiders in the Offering had not been confirmed at that time.
