About The Cariboo Gold Project
The Cariboo Gold Project is a permitted, 100%-owned feasibility-stage project currently under construction located in the historic Wells-Barkerville mining camp of central British Columbia, Canada. Spanning approximately 186,740 hectares, the Company's land package includes 443 mineral titles and covers an area that extends approximately 77 kilometres from northwest to southeast. In late 2024, the Project was granted the Mines Act and Environmental Management Act (British Columbia) permits, marking the successful completion of the permitting process for key approvals. On September 14, 2026, the Company announced a formal positive decision to proceed with the construction of the Project, with an expected first gold pour in Q1 2029 and commercial production in H2 2029.

Such forward-looking statements are not guarantees of performance and are identified with words such as "may", "will", "would", "could", "expect", "believe", "plan", "anticipate", "intend", "estimate", "potential", "propose", "project", "outlook", "foresee", "continue", "objective", "strategy", "scheduled", "target", "on track", variants of these words or the negative or comparable terminology, as well as terms usually used in the future and the conditional. Forward-looking statements in this news release include, but are not limited to, statements pertaining to: the expected timing of first gold pour, commercial production and key construction milestones at the Cariboo Gold Project, including underground development rates and targeted monthly advance rates, completion and collaring of the Valley portals, completion and full operation of the water treatment plants, completion of the waste rock storage facility, completion of the Willow River bridge, the arrival of transmission line long-lead packages, equipment deliveries, workforce ramp-up and operations readiness, including the expected timing of key hires; the ability to advance the Cariboo Gold Project through construction within the estimated budget, including the estimated project completion, the estimated remaining cost to complete construction, the expected leasing of equipment and estimated pre-production revenue, and the award of remaining contract packages; the expected performance of JDS under the project and construction management services agreement and the underground mine development contract; the Cariboo Gold Project's permitting status and the expected timing of receipt of the licence of occupation for the transmission line and of remaining authorizations, permit amendments and construction permits; continued engagement with First Nations and other stakeholders; the Company's planned drilling programs, including their scope, timing and the expected metres to be drilled by year-end, the timing of release of pending assay results, and the potential for resource conversion (if any); the Company's objective of becoming an intermediate gold producer; and the exploration potential and potential for future discoveries (if any) 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: construction proceeding on the anticipated schedule and within the estimated budget; the accuracy of the estimated remaining cost to complete and its underlying assumptions, including inflation, labour costs, exchange rates, the availability of equipment leasing on anticipated terms and gold prices realized on pre-production revenue; underground development rates improving as anticipated, including following the availability of additional headings through the Valley portals; the availability of personnel, contractors, equipment, supplies and infrastructure, including the timely delivery of long-lead items and mobile equipment; JDS and other contractors performing as expected; the absence of work stoppages or suspensions at the Cariboo Gold Project; the absence of unforeseen ground conditions or other geological challenges; required permits, authorizations and amendments being obtained and maintained in a timely manner; the continued support of First Nations and other stakeholders; the availability of drill rigs and personnel, and the ability of drilling and sampling to accurately predict mineralization; the Company's continued access to capital on acceptable terms; and the absence of material adverse changes in gold prices, foreign exchange rates and general economic and market conditions. Osisko Gold considers its assumptions to be reasonable based on information currently available but cautions the reader that its assumptions regarding future events, many of which are beyond the control of Osisko Gold, may ultimately prove to be incorrect since they are subject to risks and uncertainties that affect Osisko Gold and its business.
Such risks and uncertainties include, but are not limited to: risks associated with the development and construction of the Cariboo Gold Project, including construction delays, cost overruns, inflation and supply chain disruptions; underground development rates failing to improve as anticipated; work stoppages or suspensions at the Cariboo Gold Project; unforeseen ground, geotechnical or water management conditions; delays in commissioning of infrastructure, including the water treatment plants; contractor performance, including under the project and construction management services agreement and the underground mine development contract; delays or shortages in necessary equipment, supplies and infrastructure, including long-lead items; the inability to obtain equipment leasing on acceptable terms; pre-production revenue being lower than estimated; labour shortages, difficulties in recruiting key personnel and health and safety incidents; risks relating to third-party approvals, including the issuance of permits by governments, favourable regulatory conditions and approvals, capital market conditions and the Company's ability to access capital on terms acceptable to the Company for the contemplated exploration and development at the Company's properties; regulatory framework and presence of laws and regulations that may impose restrictions on mining; errors in management's geological modelling; the timing and ability of the Company to obtain and maintain required approvals and permits; the results of exploration activities, including the risk that further drilling does not support resource conversion; risks relating to exploration, development and mining activities; the global economic climate; fluctuations in metal and commodity prices; fluctuations in the currency markets; environmental risks; and community, non-governmental and governmental actions, including relationships with First Nations, and the impact of stakeholder actions. Readers are urged to consult the disclosure provided under the heading "Risk Factors" in the Company's annual information form for the year ended December 31, 2025 as well as those risks and factors disclosed in the Company's most recent financial statements and management's discussion and analysis and other public filings filed under Osisko Gold's issuer profile on SEDAR+ (www.sedarplus.ca) and on the SEC's EDGAR website (www.sec.gov), for further information regarding the risks and other factors facing the Company, its business and operations.
