Generation Mining Files Final Base Shelf Prospectus and Updates Shareholders

TORONTO–(BUSINESS WIRE)–Generation Mining Limited (TSX:GENM, OTCQB: GENMF) (“Gen Mining” or the “Company”) is pleased to announce that it has filed a final short form base shelf prospectus (the “Prospectus“) with the securities regulatory authorities in each of the provinces and territories of Canada, except Quebec.

The Company has filed the Prospectus in order to have greater financial flexibility going forward but has no immediate plans to issue any securities under it at this time, and may never proceed with any such issuance. Upon issuance of a receipt for the Prospectus by the securities regulatory authorities, the Company may issue and sell up to C$60,000,000 in the aggregate of common shares, debt securities, warrants, subscription receipts, units, or any combination thereof, from time to time, over the 25-month period that the Prospectus remains effective. Should the Company decide to offer securities during the 25-month effective period, the specific terms, including the use of proceeds, will be set forth in a prospectus supplement to the Prospectus, which will be filed with the applicable Canadian securities regulatory authorities.

“As the Generation team continues to advance the Marathon Palladium-Copper Project toward final construction permits and eventual production, global macro events independent of our project can benefit our shareholders,” said Jamie Levy, President and CEO of the Company. “Over the next 25 months, this prospectus will ensure that Generation can rapidly raise capital when access is available on favourable terms.”

This news release does not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities, in any province, state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such province, state or jurisdiction.

Upon issuance of the receipt, a copy of the short form base shelf prospectus can be found under the Company’s issuer profile on SEDAR+ at www.sedarplus.ca.

Amended and Restated Technical Report

In addition, Table 15.6 – Measured and Indicated Mineral Resource Whittle Shell Results for Combined Diluted Model is being amended to correct labelling of certain metal grade columns and Table 16.1 – Pit Phase Design Summary and Table 16.3 – Shell and Design Comparison are being amended to correct an error in how certain weighted average grades were calculated.
