SnapshotThe Lomada de Leiva mining operations were placed on care and maintenance in 2022, while leaching of previously stacked material on the heap leach pad continued.

There was no production at Lomada during 2024 and the three months ended March 31, 2025, as the site transitioned into closure activities. No further residual production is expected. The heap leach pad was washed to reduce cyanide levels to the required regulatory thresholds. As of the end of May 2025, all fieldwork was suspended for the winter season and is expected to resume and be finalized in the third quarter of 2025.

As of March 31, 2025, Patagonia Gold Corp. reported reclamation and remediation obligations for Lomada totaling $0.70 million.

Summary:

The Lomada gold deposit, located south-southeast of the community of Perito Moreno. in the western part of the Deseado Massif, is a classic, low-sulfidation epithermal mineral system. Precious metal mineralization at Lomada is hosted in a NNE-striking, steeply ESE-dipping structure (the “Main Breccia”).

-Low sulphidation, epithermal gold system hosted in a NNEstriking, steeply ESE-dipping structure (Main Breccia)
- Previous mining occurred from a portion of the Main Breccia over a 600 m strike, up to 20 m width and more than 150 m in depth.

Although the Patagonia has commenced extraction of minerals at the Lomada properties, the Patagonia does not have defined mineral reserves as defined under Regulation S-K and therefore mining propertie is considered to be in the exploration stage.
