TORONTO, Aug. 20, 2026 (GLOBE NEWSWIRE) -- Osisko Gold Group Inc. (NYSE: OGG, TSXV: OGG) ("Osisko Gold" or the "Company") is pleased to announce that it has entered into an amended and restated credit agreement (the "Amendment") with funds advised by Appian Capital Advisory Limited ("Appian") in respect of its US$450 million senior secured project loan credit facility dated July 21, 2025 (the "Credit Facility"). The Credit Facility was entered into by the Company's wholly owned subsidiary, Barkerville Gold Mines Ltd. ("Barkerville"), to finance the development and construction of the Company's 100%-owned, fully permitted Cariboo Gold Project (the "Project").

The Amendment provides the Company with more favourable covenants, reduces the overall cost of capital, and extends the Company's option to settle accrued interest in kind ("PIK") for an additional 12 months. Importantly, following Appian&s review of the results of work completed to date, Appian has confirmed satisfaction of certain key technical conditions precedent to the US$350 million second draw under the Credit Facility, including those related to the Lowhee Zone infill drilling and ore sorting programs, and these conditions have been removed from the Credit Facility pursuant to the Amendment. The second draw remains subject to certain remaining conditions precedent associated with ongoing Project-related construction readiness activities and other customary requirements.

Sean Roosen, Chairman and CEO, commented: "The amended terms of this credit facility provide us with meaningful financial flexibility as we advance the Cariboo Gold Project toward construction readiness. Appian's confirmation that the key technical conditions precedent have been satisfied, including those related to the completed Lowhee infill drilling and ore sorting programs, represents an important validation of the quality of this deposit and the significant de-risking work our team has completed. With the improved economics under the Amendment and US$350 million of additional capital now substantially de-risked, we are well positioned to continue advancing toward our next major development milestones. We thank Appian for its continued partnership and look forward to working together through the next phase of development at Cariboo."

The Amendment provides for a reduction in applicable interest rate margins under the Credit Facility as follows: (i) for the initial draw, 3-month Secured Overnight Financing Rate ("SOFR") plus a margin of 9.00% per annum (reduced from SOFR plus 9.50% per annum), together with the elimination of the 0.10% per annum SOFR adjustment; and (ii) for the second draw and thereafter, SOFR plus a margin of 7.25% per annum (reduced from SOFR plus 7.50% per annum).

All of the existing guarantees, security and other obligations provided for under the Credit Facility remain in full force and effect and have been reaffirmed in connection with the Amendment. Except as expressly amended, all other terms of the Credit Facility remain unchanged. Barkerville paid an amendment fee to Appian in connection with the Amendment.

The description of the Amendment set forth in this news release is a summary only and is qualified in its entirety by the full text of the amended and restated credit agreement dated August 20, 2026 among Barkerville, as borrower, Appian, as lender, TSX Trust Company, as collateral agent, and Appian ODV (Jersey) Ltd., as administrative agent. A copy of the Amendment will be filed on SEDAR+ (www.sedarplus.ca) under the Company's issuer profile.

Such forward-looking statements relate to, among other things: the expected benefits of the Amendment, including reduced interest rate margins, improved covenants, and extended PIK interest settlement options; the anticipated satisfaction of remaining conditions precedent to the second draw under the Credit Facility; the Company&s ability to access the remaining US$350 million available under the Credit Facility; the advancement of construction readiness activities, detailed engineering, procurement, and project de-risking initiatives at the Cariboo Gold Project; the Company&s objective of becoming an intermediate gold producer; and the exploration potential and prospectivity of its properties.

Information contained in forward-looking statements is based upon certain material assumptions that were applied in drawing a conclusion or making a forecast or projection, including: the Company&s ability to satisfy the remaining conditions precedent to the second draw under the Credit Facility; the continued availability of financing under the Credit Facility on the terms described herein; the timing and successful completion of the second draw; the Company&s ability to advance the Cariboo Gold Project through construction readiness on the anticipated timeline and budget; the continued support of Appian and the absence of any event of default under the Credit Facility; the ability to develop the Cariboo Gold Project and its status as being fully permitted; the Company&s objective of becoming an intermediate gold producer; and the exploration potential and potential for future discoveries (if any) of its properties. Such forward-looking statements are based on a number of risks, uncertainties and assumptions which may cause actual results or other expectations to differ materially from those anticipated and which may prove to be incorrect. These assumptions include, but are not limited to: the absence of any work stoppages or suspensions at the Company's projects; favourable regulatory conditions and approvals; the ability to maintain adequate personnel and contractor levels; the absence of unforeseen ground conditions or other geological challenges; the availability of necessary equipment, supplies and infrastructure; and general economic and market conditions. Actual results could differ materially due to a number of factors, including, without limitation: failure to satisfy remaining conditions precedent to the second draw under the Credit Facility; changes in the terms of the Credit Facility or the occurrence of an event of default thereunder; risks related to the exploration, development and operation of the Cariboo Gold Project; changes in estimated project costs, development timeline, or construction schedule; health, safety and security incidents; regulatory delays or changes in regulatory framework and applicable laws; labour shortages or disputes; general economic and market conditions and business conditions in the mining industry; fluctuations in commodity and currency exchange rates; changes in interest rates affecting the cost of borrowing under the Credit Facility; as well as those risks and factors disclosed in the Company's most recent annual information form, financial statements and management's discussion and analysis as well as other public filings on SEDAR+ (www.sedarplus.ca) and on EDGAR (www.sec.gov).
