Mining and milling at this operation were previously suspended in the first quarter of fiscal year 2020 (Q1 FY20), after mineral reserves at the location were depleted.
Since then, Orvana has focused on processing oxide materials stockpiled from earlier stages of mining at the site.
The current project includes plans to expand production capabilities for copper cathodes and an upgrade to the gold-silver recovery circuit within the Don Mario processing plant.
EMIPA has stated that its immediate efforts will centre on the gradual increase of processing throughput and the optimisation of metallurgical performance at the expanded facility.
The company aims to advance towards full commercial production of both gold-silver doré and copper cathodes, while maintaining strict cost controls.
Future production levels, particularly through FY26, are expected to depend on successful ramp-up activities, ongoing plant performance and the stabilisation of all processing circuits.
Orvana CEO Juan Gavidia said: “The first doré bar from EMIPA’s oxides confirms that the metallurgical performance of the expanded Don Mario Plant is in line with design and engineering assumptions.
“We remain focused on safely increasing throughput and optimising plant performance as operations ramp up.”
Orvana’s assets include the Orovalle mine in northern Spain and the Taguas property in Argentina. The company extracts gold, copper and silver across these sites.
In June 2026, the company expanded its land holdings at the Taguas Project in San Juan Province following the acquisition of the Evelina claims from a subsidiary of Pan American Silver for $1.2m (C$1.7m).
