ORVANA ANNOUNCES THE RESTART OF ITS DON MARIO PLANT IN BOLIVIA

Orvana Minerals Corp. has initiated a phased restart of its Don Mario processing plant in Bolivia.

Juan Gavidia, chief executive officer of Orvana, commented:

"The restart of the Don Mario plant represents an important milestone for Orvana as we advance the commissioning of our expanded processing facilities. Our focus remains on executing a disciplined and phased start-up designed to manage commissioning risk, validate plant performance and position the operation for a controlled ramp-up in 2026."

Orvana's Bolivian subsidiary, Empresa Minera Paititi S.A. (EMIPA), has commenced the initial phase of the plant restart, with the comminution and thickening circuits brought on line to supply feed to the gold-silver circuit. These circuits are expected to undergo performance verification through mid-January, 2026. The copper circuit, which forms part of the Don Mario plant expansion, is scheduled to be brought on line in the second half of January, 2026, followed by a controlled ramp-up of all circuits from February through April, 2026.

The Don Mario plant expansion includes:

1. The installation of new circuits for copper oxide processing, including acid leaching, filtration, solvent extraction and electrowinning to produce copper cathodes;
2. Enhancements to the gold-silver and detox circuits to improve throughput and technological performance;
3. A comprehensive overhaul of pre-existing comminution and thickening circuits;
4. Business-readiness initiatives, including upgrades to power generation, laboratories, warehouses and workshops, as well as recruitment and training of personnel.

Concurrent with commissioning activities, EMIPA is conducting final on-site pilot testing. Upon completion, the pilot testing, together with existing metallurgical data, are expected to allow the company to update its metal production estimates derived from processing the oxide stockpiles at Don Mario. The company expects to provide updated information once testing results have been validated.
