SnapshotThe Lomada de Leiva mining operations were put on care and maintenance during 2022 while leaching of the material previously placed on the leach pad continued. During 2023, production has been declining as a result of no fresh material being added to the pad.

During the year ended December 31, 2024, gold and silver production ceased as Lomada commenced closure activities. No further residual production is expected. The heap leach pad was washed to reduce cyanide levels to the required levels and closure and remedy activities are underway. As of the end of May 2025, all field work was suspended for the winter season and will be resumed and finalized during Q3 2025.

  • Epithermal

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.
