Orvana Minerals Corp. provides updates on the Oxides Stockpile Project at its Don Mario operation in Bolivia, and reports results for the quarter ended June 30, 2026 ("Q3 FY2026").

" We are very excited that our new Bolivian Copper Cathodes Circuit, and our revamped Gold-Silver Dore Circuit, have entered the commercial production ramp-up phase, after overcoming logistical hurdles in Bolivia during May and June. Our Bolivian team is focused on executing a safe and disciplined ramp-up, with the goal of achieving stable commercial production in September 2026 " said Juan Gavidia, Chief Executive Officer of Orvana Minerals. "This positive momentum for Bolivia, together with the doubling of our exploration area at Taguas, Argentina, through the acquisition of Evelina, reflects the disciplined execution of the growth strategy Orvana has pursued in recent years" , added Mr. Gavidia

Bolivia – EMIPA Oxides Stockpile Project ("OSP") Completed commissioning of Crushing, Milling, Thickening, Acid Leaching, Filtration (source of both Copper PLS-Pregnant Leach Solution and Gold-Silver cake), Copper Cathodes Circuit (SX-EW), and Gold-Silver Dore Circuit (CN Leach plus ADR). With the production of copper PLS and gold-silver cake established in July, ramp-up activities across the copper and precious metals circuits are currently progressing in August, as planned. Operational efforts remain focused on achieving stable commercial production in September 2026. The timing of the ramp-up and attainment of targeted production levels remain subject to operational performance and market conditions.

FY2026 Revised Guidance: During May and June 2026 (Orvana Q3 FY2026) Bolivia experienced 53 days of significant civil unrest, including nationwide strikes and road blockades, which disrupted the movement of goods and personnel across the country and materially impacted logistics and supply chains. While logistics have fully normalized as of the date of this news release, these disruptions delayed the execution of the OSP by 60 days for some items, and for more than 90 days in some others. As a result of the operational delays arising mainly from the logistics disruptions, EMIPA updated its production plan and has accordingly revised its guidance for fiscal 2026:
