TORONTO, Aug. 13, 2026 /PRNewswire/ -- Orvana Minerals Corp. (TSX: ORV) (OTCQX: ORVMF) (the "Company" or "Orvana") 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:

Spain – Orovalle

• ­Orovalle produced 10,833 gold equivalent ounces⁽⁵⁾ ("GEO") during Q3 FY2026, approximately 10% higher than the 9,827 GEO⁽⁵⁾ produced in the previous quarter. The primary drivers of the variance between Q3 FY2026 and the prior quarter were:
  • The mill processed approximately 131,244 dry tonnes during Q3 FY2026, in line with 130,506 dry tonnes in the prior quarter, supported by tonnage mined from parallel operations at El Valle Boinás and Carlés mines.
  • 9,656 gold ounces produced in Q3 FY2026, 14% higher than the previous quarter primarily due to 13% higher gold grade.
  • 0.6 million copper pounds produced in Q3 FY2026, 17% lower than the previous quarter primarily due to 6% lower copper grade and 11% lower recovery.
  • Quarter–over–quarter grade movements reflect changes in oxide and skarn proportions associated with ore extraction and blending sequencing.
  • Variations in copper recovery reflected changes in processed ore grades and metallurgical adjustments to the flotation process designed to maintain concentrate quality specifications, including the control of deleterious elements.
• ­In Q3 FY2026, Orovalle completed 3,712 metres of drilling at its El Valle mine, primarily focused on Breccia East and Area 208 orebodies. Drilling remains ongoing at El Valle mine.
• ­FY2026 Guidance: Orovalle is currently on track to meet FY2026 Guidance, based on results to date and current operating assumptions, although actual results may differ materially depending on operational performance and market conditions (see "Cautionary Statements - Forward-Looking Information"). The following table sets out Orovalle's results for the first nine months of fiscal 2026 and fiscal 2026 production, capital expenditures and costs ⁽⁵⁾ guidance:

Argentina – Taguas Project

• ­The Company conducted its first deep drilling campaign targeting deeper mineralized systems on the Taguas property between late January and early May 2026. The program comprised 2 drill holes, totaling 2,173.7 metres drilled. First drill hole TADD278 reached 1,331.7 metres and second TADD279, 842 metres. The FY2026 program concluded in anticipation of the winter season. The second drill hole has been cased, preserving the option to resume and continue drilling during the next summer field campaign.
• ­Petrographic studies completed on drill core samples from hole TADD-278 indicate that the mineralized host rock corresponds to a dacitic porphyry. The analyzed intervals display a well-developed porphyritic texture characterized by quartz, plagioclase and subordinate mafic phenocrysts set within a strongly silicified and sericitized groundmass, consistent with a hydrothermal porphyry system. The studies also identified intense sericitic alteration assemblages dominated by quartz-sericite-pyrite. Sulfide mineralization is primarily composed of pyrite with associated enargite and/or chalcopyrite, occurring as disseminations and veinlet fillings, further supporting the interpretation of a dacitic porphyry-related hydrothermal system. Additional information is available in the Company's news release dated July 2, 2026.
• ­Petrographic studies on TADD-279 and vectoring studies are currently underway. The company also plans to undertake geochronological studies on selected drill core samples to constrain the timing of the different porphyry intrusion phases and enhance its understanding of the hydrothermal system's temporal evolution.
• ­In July 2026, the Company completed a technical review workshop involving specialists in porphyry and epithermal systems. The workshop reviewed geological, geochemical, mineralogical, structural and alteration datasets and provided independent input to support refinement of the exploration model.
• ­At the end of June 2026, the Company acquired the Evelina property, comprising four claims totalling 4,015 hectares. The addition of the Evelina Property increases the Taguas Project's exploration footprint by approximately 123%, from 3,274 to 7,289 hectares. Located immediately south of the main Taguas property, the Evelina property extends the Taguas Project along the same metallogenic belt, highlighting the potential continuity of a prospective epithermal corridor supported by early geological evidence. The acquisition provides opportunities to expand exploration activities at the Taguas Project while enhancing logistical flexibility and optionality for potential future infrastructure development. Additional information is available in the Company's news release dated June 29, 2026.
• ­Drawing on all geological, geochemical, mineralogical and structural information generated during FY2026, together with the historical data available for the Evelina property, the Company will define the scope and priorities of the FY2027 exploration program at the Taguas Project.
