The Company has established the Omai Gold Project as one of the fastest growing and well-endowed gold camps in the prolific Guiana Shield. In August 2025, the Company announced a 96% increase to the Wenot Gold Deposit NI 43-101 Mineral Resource Estimate1 (MRE) to 970,000 ounces of gold (Indicated) averaging 1.46 g/t Au, contained in 20.7 Mt and 3,717,000 ounces of gold (Inferred MRE) averaging 1.82 g/t Au, contained in 63.4 Mt. This brings the global MRE at Omai, including the Wenot and adjacent Gilt deposit, to 2,121,000 ounces of gold (Indicated MRE) averaging 2.07 g/t Au in 31.9 Mt and 4,382,000 ounces of gold (Inferred MRE) averaging 1.95 g/t Au in 69.9 Mt. The Company completed 39,000m of diamond drilling in 2025. An updated MRE is planned for Q1 2026 to be followed by an updated Preliminary Economic Assessment (&#34;PEA&#34;) in Q2, that will include the Wenot open pit deposit and the adjacent Gilt underground deposit. Three drills have commenced the 2026 drill program: at Wenot the focus is to further test the limits of the deposit, including both east and west, and to commence upgrading the large Inferred MRE to Indicated. Additional drilling will continue to explore certain known gold occurrences for possible near-surface higher-grade satellite deposits. The Omai Gold Mine produced over 3.7 million ounces of gold from 1993 to 20052, ceasing operations when gold was below US$400 per ounce. The Omai brownfields project benefits from known metallurgical recoveries, existing tailings facilities, and infrastructure, including an on-site airstrip, and road access, connecting to the two largest cities in Guyana, Georgetown and Linden. 1 NI 43-101 Technical Report dated October 9, 2025 titled &#34;UPDATED MINERAL RESOURCE ESTIMATE AND TECHNICAL REPORT ON THE OMAI GOLD PROPERTY, POTARO MINING DISTRICT NO.2, GUYANA&#34; was prepared by P&amp;E Mining Consultants Inc. and is available on www.sedarplus.ca and on the Company's website.2 Past production at the Omai Mine (1993-2005) is summarized in several Cambior Inc. documents available on www.sedarplus.ca, including March 31, 2006 AIF and news release August 3, 2006.Qualified Person Elaine Ellingham, P.Geo., is a Qualified Person (QP) under National Instrument 43-101 &#34;Standards of Disclosure for Mineral Projects&#34; and has reviewed and approved the technical information contained in this news release.
