BONTERRA EXECUTES DEFINITIVE OPTION AGREEMENT WITH OSISKO MINING ON BONTERRA'S URBAN-BARRY PROPERTY

Bonterra Resources Inc. has executed a definitive earn-in and joint venture agreement with Osisko Mining Inc., further to the news release of Bonterra dated Sept. 25, 2023, and entitled "Bonterra Announces Binding Letter Agreement for Joint Venture with Osisko Mining." Under the agreement, Osisko has the right to acquire up to a 70-per-cent interest in the company's Gladiator and Barry projects, in addition to the adjoining Duke and Lac Barry properties held through joint venture agreements with Osisko and Gold Royalty Corp., respectively, all located in Quebec's Eeyou Istchee James Bay region and consisting of an aggregate of 496 claims over 22,508 hectares.

Pursuant to the terms of the agreement, Osisko has paid the company initial upfront payments totalling $5-million. Osisko can earn a 70-per-cent interest in the properties, reducing the company's interest in the Gladiator, Barry and Duke properties to 30 per cent and its interest in the Lac Barry joint venture to 15 per cent by expending $30-million on qualifying expenditures on the properties over the next three years. Specific terms of the agreement include:

• Completion of $30-million in work expenditures on the properties, with a minimum spending commitment of $10-million per year over the three-year period following the execution of the agreement;
• Osisko will have the right to carry over work expenditures from year to year, and to pay cash in lieu of expenditures in the event of a shortfall;
• Osisko will be the operator for the properties during the exploration earn-in period;
• Once a 70-per-cent interest in the properties is earned by Osisko, the properties will be operated as a joint venture, with Osisko as the operator, and each party required to contribute to future work expenditures in accordance with the proportional interests in the joint venture;
• Dilution of a party to less than 10 per cent of the joint venture will result in the conversion of their respective joint venture interest to a 1-per-cent net smelter return royalty, 50 per cent of which is subject to a buyback right of $1-million;
• In its sole discretion, Osisko may accelerate its exercise of the earn-in right.

Marc-Andre Pelletier, chief executive officer and president of the company, commented: "We're excited to announce our partnership with Osisko on the properties. With a $30-million exploration budget over three years and leveraging Osisko's expertise in this prolific gold camp, we believe we're well positioned for significant exploration and development success on the Gladiator and Barry projects. Concurrently, we have three drill rigs turning at our 100-per-cent-owned Desmaraisville property near the Bachelor mill complex and are focusing on high-grade intercepts that were previously drilled, but not followed up on.

"With the additional $4-million received on closing ($1-million already received) and the revenue streams from leasing the Bachelor camp and selling gold from the mill clean-up, we expect to have ample funds to complete this year's more than 15,000 metres drill campaign at the Desmaraisville properties."

The agreement has been approved by the TSX Venture Exchange.

As payment for its role as the company's financial adviser in connection with the joint venture, Cormark Securities Inc. received an advisory fee of $200,000 in cash and $200,000 in common shares of the company. McMillan LLP acted as the company's legal adviser in connection with the joint venture. Bennett Jones LLP acted as Osisko's legal adviser in connection with the joint venture.
