(TSX-V: ODV ) is pleased to announce the successful completion of its previously-announced “bought deal” brokered private placement of an aggregate of: (i) 2,055,742 flow-through shares of the Corporation at a price of CDN $9.05 per FT Share; and (ii) 1,334,500 charity flow-through shares of the Corporation at a price of CDN $11.24 per Charity FT Share, for aggregate gross proceeds of approximately CDN $33.6 million, including partial exercise of the underwriters’ option. The Offered Shares will qualify as “flow-through shares” (within the meaning of subsection 66(15) of the Income Tax Act (Canada)).

The gross proceeds from the sale of the Offered Shares will be used by the Corporation to incur eligible “Canadian exploration expenses” that will qualify as “flow-through mining expenditures” as such terms are defined in the Income Tax Act (Canada) related to the Cariboo Gold Project and other exploration assets of the Corporation located in British Columbia. All Qualifying Expenditures will be renounced in favour of the subscribers of the Offered Shares effective December 31, 2021.

The Offering was led by Eight Capital, on behalf of a syndicate of underwriters that included Canaccord Genuity Corp., National Bank Financial Inc., RBC Dominion Securities Inc., TD Securities Inc., BMO Nesbitt Burns Inc., PI Financial Corp., Scotia Capital Inc., CIBC World Markets Inc., Desjardins Securities Inc., Haywood Securities Inc., iA Private Wealth Inc., Paradigm Capital Inc., and Raymond James Ltd. In consideration for their services, the Corporation paid the underwriters a cash commission equal to 5.5% of the gross proceeds of the Offering, except with respect to subscribers on the President’s List for which no commission was paid.

The following insiders of the Corporation have subscribed for FT Shares under the Offering:

The Corporation is relying on exemptions from the formal valuation and minority shareholder approval requirements available under MI 61-101. The Corporation is exempt from the formal valuation requirement in section 5.4 of MI 61-101 in reliance on section 5.5(a) of MI 61-101 as the fair market value of the transaction, insofar as it involves interested parties, is not more than the 25% of the Corporation’s market capitalization. Additionally, the Corporation is exempt from minority shareholder approval requirement in section 5.6 of MI 61-101 in reliance on section 5.7(b) of MI 61-101 as the fair market value of the transaction, insofar as it involves interested parties, is not more than the 25% of the Corporation’s market capitalization.
