TORONTO, CANADA (By Orvana, 25.May.2026, Words: 389) — Orvana Minerals Corp. updated shareholders and the market on ongoing transport and logistics disruptions in Bolivia and their impact on the company’s Oxide Stockpile Project (“OSP”) at its Don Mario operation, operated through its controlled subsidiary Empresa Minera Paitiítí S.A. (EMIPA).
Bolivia is currently experiencing significant civil unrest, including nationwide strikes and road blockades, which are disrupting the movement of goods and personnel across the country. These conditions are materially impacting logistics and supply chains nationwide.
The situation remains fluid and unresolved as of the date of this news release. The company is monitoring developments on a continuous basis.
Impact on the OSP
As previously reported in its management’s discussion & analysis (MD&A) for the 3 and 6 months ended 31 Mar. 2026, dated 12 May 2026, EMIPA successfully completed the verification phase of the Don Mario plant’s Au–Ag circuit during the quarter ended 31 Mar. 2026, producing 959 gold ounces and 1,079 silver ounces of doré from the processing of legacy sulphide ore. Following completion of the Au–Ag testing phase, EMIPA advanced the commissioning and integration of the copper leaching, solvent extraction and electro–winning circuits, with the expanded plant undergoing final testing and operational readiness verification.
The commencement of oxide ore processing at Don Mario is being directly impacted by constraints on the supply of required materials, driven by ongoing supply chain and logistical disruptions.
EMIPA continues to take all available steps to advance the OSP, including evaluating alternative and in–country sourcing options where feasible. Personnel safety and security at the Don Mario site remain a priority, and the Company continues to monitor conditions closely.
Outlook
The company will provide further updates as the situation in Bolivia evolves and as the impact on EMIPA’s operations becomes clearer.
As a result of the previously described conditions, the commencement of oxide ore processing will be delayed beyond the previously communicated timeline. The company is not in a position to provide a revised start–up date at this time. Orvana will update the market when sufficient clarity becomes available.
The company will reassess EMIPA’s guidance once greater visibility is available regarding the duration and operational impact of the current disruptions.
Orvana’s primary focus at this time remains the safety of its personnel at Don Mario, together with continued engagement with Bolivian authorities on operational matters.
