On August 12, 2020, the Company announced recommencement of mining and leaching operations at its Lomada de Leiva mine.
Following receipt of a preliminary permit in October 2020, the Company restarted operations at Lomada. In addition to production from this restart, the Company continues to recover precious metals from residual leaching of material already placed on the heap leach pad. On March 9, 2021, the Company announced that it had received a definitive environmental permit for Lomada. |

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.
Summary:
Lomada is located in the La Paloma property block approximately 120 kilometers to the north of the El Tranquilo property block in the Santa Cruz province of Argentina.
The Lomada mine was closed in May 2016 while production from the ongoing leaching continues, though at a reduced output. Given that the mineralized material from the Lomada open pit mine was originally placed on the heap leach pad without crushing, the Company decided to return to Lomada to reprocess this mineralized material. However, in mid-February 2019 the Company took the decision to cease operations and proceed with the closure of Lomada. During the year ended December 31, 2020, the Company was working on re-handling material of leach pad to regenerate the solution percolation and generate new channels of circulation of solution.
The Company received the final approval in November 2019 and started with the work of remediation at the end of 2019. Following receipt of a preliminary permit in October 2020, the Company restarted operations at Lomada. The mine is currently operating at a rate of 120,000 tonnes/month of total material. In the leach pad area, road construction has been completed and new mineralized material is being placed on the pad to be leached.

Reserves at December 31, 2017:
In 2020 the Company does not have a current Mineral Reserve estimate for the Lomada mine though the recommencement of mining and gold recovery is expected to come from an extension of the mineralized structure modeled in connection with a 2007 JORC compliant technical report, there are risks associated with commencing mining without current Mineral Reserves.
