Bonterra Announces Closing of $11.66 Million Private Placement

Val-d'Or, Quebec--(Newsfile Corp. - October 21, 2021) - Bonterra Resources Inc. (TSXV: BTR) (OTCQX: BONXF) (FSE: 9BR2) ("Bonterra" or the "Company") is pleased to announce that it has closed the brokered private placement previously announced on September 27, 2021 (the "Offering").

Pursuant to the Offering, Bonterra issued 7,935,000 common shares (each a "Common Share") of the Company that qualify as "flow-through shares" (the "FT Shares") at a price of $1.47 per FT Share for gross proceeds of $11,664,450.

Cormark Securities Inc. acted as lead agent on behalf of a syndicate of agents which included Red Cloud Securities Inc. (collectively, the "Agents"). In connection with the Offering, the Agents received a cash fee equal to 6.0% of the gross proceeds from sales of the FT Shares under the Offering to subscribers other than those on the President's List and a cash fee equal to 2.0% of the gross proceeds from the sale of the FT Shares to subscribers from the President's List.

The gross proceeds from the issuance of the FT Shares will be used for "Canadian exploration expenses" that qualify as "flow-through mining expenditures", as both terms are defined in subsection 127(9) of the Income Tax Act (Canada) (the "Qualifying Expenditures"), related to the Company's projects in Québec which will be incurred on or before December 31, 2022 and renounced to the subscribers with an effective date no later than December 31, 2021 in an aggregate amount not less than the gross proceeds raised from the Offering. In addition, with respect to Québec resident subscribers who are eligible individuals under the Taxation Act (Québec), the Canadian exploration expenses will also qualify for inclusion in the "exploration base relating to certain Québec exploration expenses" within the meaning of section 726.4.10 of the Taxation Act (Québec) and for inclusion in the "exploration base relating to certain Québec surface mining expenses or oil and gas exploration expenses" within the meaning of section 726.4.17.2 of the Taxation Act (Québec). If the Qualifying Expenditures are reduced by the Canada Revenue Agency, the Company will indemnify each FT Share subscriber for any additional taxes payable by such subscriber as a result of the Company's failure to renounce the Qualifying Expenditures as agreed.

The FT Shares issued in the Offering are subject to a statutory hold period of four months and one day from the date of issue in accordance with applicable securities laws. The Offering remains subject to final approval by the TSX Venture Exchange.
