Patagonia Gold Corp Commences Leaching Operations At Calcatreu Project Patagonia Gold Corp. has announced the successful commencement of leaching operations at its flagship Calcatreu Project in Rio Negro Province, Argentina. This milestone represents a significant advancement as the Project transitions into its gold recovery cycle. The initiation of leaching activities follows the completion of construction, commissioning of key infrastructure, and the placement of mineralized material on the heap leach pad. With all necessary regulatory approvals in place and operational systems fully tested, the Company has now begun applying leach solution to the stacked ore. The commencement of leaching follows the construction and stacking progress update announced in January and confirms advancement in line with the Company’s previously communicated development sequence. Key processing infrastructure, including the carbon-in-column (CIC) circuit, is now operational. The Company has over 91,300 tonnes of material from the Veta 49 pit, consisting of 73,300 tonnes crushed and stockpiled, and 18,800 tonnes stacked on the leach pad. The Project is being developed on a prominent, multi-vein, epithermal gold and silver mineral system located in the mining-friendly jurisdiction of Rio Negro Province. Development activities have been conducted in accordance with international best practices for environmental stewardship, safety, and community engagement. The Company continues to prioritize sustainable operations and meaningful partnerships with local communities. Leaching operations will continue on stacked mineralized material with ongoing monitoring of solution flow and recovery performance. Subsequent stages are expected to include loaded carbon processing and doré production as part of normal heap-leach operating cycles. Timing of gold recovery will depend on operational and metallurgical factors typical of heap leach operations. NCL Ltda. continues to progress the updated technical report on Calcatreu, prepared in accordance with National Instrument 43-101, expected for release in Second Quarter 2026, which will incorporate updated technical information for the Project. Donald J. Birak, an independent consulting geologist, Registered Member of SME, Fellow of AusIMM, and qualified person as defined by National Instrument 43-101, has reviewed and approved the scientific and technical information in this news release.

Patagonia Gold Corp. Provides Update on Construction of Calcatreu Project in the Province of Rio Negro, Argentina Patagonia Gold Corp. provided this update on construction of the Calcatreu Project, in the Province of Rio Negro, Argentina. Construction work resumed on January 5, 2026, following a short hiatus over the holiday period. Approximately 40,000 tonnes of mineralized material, extracted from the new Veta 49 pit, have been stockpiled and 5,200 tonnes of said mineralized material are expected to be stacked on the leach pad after electric leak detection tests are performed later this month. This represents a key milestone as the Project moves closer to the commencement of leaching operations. Construction of the carbon-in- column ("CIC") circuit of the plant resumed and is also expected to be finalized this month. Once leaching and processing of the stockpiled material commences the resulting metal dore will be shipped to Asahi Refining Canada in Ontario, Canada. The new camp for the Project is being commissioned and dining facilities for 140 people were recently completed - both of which strengthen the Project's operational capacity. NCL Ingenieria y Construccion Ltda continues to advance a technical report prepared in accordance with National Instrument 43-101 on the Project, which is expected to be released in second quarter 2026 and will provide the market with an updated technical basis for the Project.

Patagonia Gold Corp. Provides an Update on the Construction of the Calcatreu Project Patagonia Gold Corp. provided an update on the construction of the Calcatreu project, the Company's project in the Province of Rio Negro, Argentina. The Project is located in the southern portion of the Rio Negro Province, 85 km south of the community of Ingeniero Jacobacci. The Project is centered on a low sulfidation, epithermal gold and silver system with mineralization outcropping at the surface. The first section of the leach pad, necessary to commence leaching, has been completed and during January 2026, electric leak location tests will be performed. Thereafter, loading of mineralized material will commence with the material previously mined and stockpiled to date. The chemical storage facility, with capacity to hold 120 tonnes of product, was completed in December 2025. On December 23, 2025, 80 tonnes arrived on site and is being stored on the Project premises. Calcatreu currently has 135 employees, the majority of which have been recruited from the neighboring town, Ingeniero Jacobacci or within the Province of Rio Negro. A limited number of specialized positions are being filled by personnel from other provinces, where prior precious metals operating experience is available, as Calcatreu represents the first precious metals project to be developed in Rio Negro. The Company continues to work with the neighbouring communities and local and Provincial authorities and keeps them informed as to the development of the Project. The corresponding Provincial authorities visit the Project on a regular basis and are happy with the progress being made. In third quarter of 2025, the Company engaged NCL Ingeniera y Construccion to update the Project's mineral resource and mineral reserve estimates in a new technical report, to be prepared in accordance with National Instrument 43-101, which report is intended to supersede the Technical Report (as defined below), and which the Company hopes to release during second quarter of 2026.

Patagonia Gold Corp. Announces Drill Results from Piche Structure at its Calcatreu Project in the Rio Negro Province Patagonia Gold Corp. announced new analytical results from drilling on the Piche structure (“Piche”) at its Calcatreu development property (“Calcatreu” or the “Project”) in the Rio Negro Province. Calcatreu is located in the Somuncura Massif – a region of southern Argentina known for Jurassic-aged, epithermal mineral deposits. The Project’s indicated mineral resources stand at 9.8 M tonnes grading 2.11 g/t gold and 19.83 g/t Ag for 669 K and 6.3 M contained ounces of gold and silver, respectively, and inferred mineral resources of 8.1 M tonnes grading 1.34 g/t gold and 13.1 g/t silver for 348 K and 3.4 M contained ounces of gold and silver, respectively. The Project’s mineral resources were estimated with gold and silver prices of $1,300 Au and $16 Ag, respectively, and the Company expects to update the Technical Report by the end of 2025 to reflect, among other things, current metal prices, new drill results and other technical and social developments. Piche is a typical low-sulfidation epithermal precious metal deposit and lies about 150 meters southeast of the main Nelson structure with mineralization characteristics similar to those of Nelson. In November 2024, the Company announced it had received final permits for construction of the mine and heap leach pad at Calcatreu. As part of the Company’s permitted development activities at Calcatreu, a total of 7 HQ-sized core holes, totaling 300 meters, were drilled on Piche in late 2024 and early 2025 to help identify new, near surface mineralization, and for geotechnical purposes in the area of the planned heap leach site. Piche strikes northeast parallel to the majority of the other major epithermal structures on Calcatreu and, in places, consists of a main vein and a second vein in the footwall of the main structure. On average, Piche dips 75 degree to the southeast and has a current strike (NE-SW) length of over 400 meters. Gold and silver mineralization at Piche is hosted in banded quartz veins and quartz vein breccias. Mineralization currently extends from surface, as defined by trench sample analyses (“TR”), to about 1175 meters elevation and is open at depth and on strike to the NE. Tillkännagivande • Sep 03
Patagonia Gold Corp. Announces Further Advances in Calcatreu Permitting Patagonia Gold Corp. announced the progress of the Calcatreu permitting process. The Calcatreu permitting process continues to advance positively and has reached the final stage of approval. Following positive recommendations from the Secretariat of Mining and the Secretariat of Environment and Climate Change of Rio Negro and overwhelming support from the closest neighboring native community, the multidisciplinary environmental council (COPEAM), consisting of various stakeholders within the Rio Negro Province, has issued a unanimous decision in favour of the development of Calcatreu. A non-binding public hearing (the “Public Hearing”) was subsequently held on August 30, 2024 in Ing. Jacobacci, the closest city to Calcatreu. At the Public Hearing, representatives from the Company presented the Calcatreu project together with GT Ingeniería SA, the consulting firm that prepared the Environment Impact Assessment Report in respect of the project. Following these presentations, various bureaus and stakeholders made presentations and more than 200 individuals from the Rio Negro Province expressed their position regarding the mining industry and the Calcatreu project. The Public Hearing lasted just under 12 hours and the general consensus is that the Public Hearing was a success, considering the strong support expressed by the majority of the stakeholders. The next step in the approval process (which is also the last) is a final resolution to be issued by the Secretariat of Environment and Climate Change of the province of Rio Negro, formally granting the permit to construct and develop Calcatreu. This final resolution is expected to be issued within the next two months. Calcatreu is the Company´s project and is located in the southern portion of the Rio Negro Province, 85 kms south of the community of Ing. Jacobacci. The project is centered on a low sulfidation, epithermal gold and silver system with mineralization outcropping at the surface. The total measured and indicated mineral resources are estimated at 9.84 million tonnes at an average grade of 2.11 g/t Au and 19.8 g/t Ag (2.36 g/t gold equivalent) and 8.08 million tonnes of inferred mineral resources grading 1.34 g/t Au and 13.1 g/t Ag (1.5 g/t gold equivalent), as disclosed in the Technical Report (as defined below). Once the final resolution has been issued, the Company expects to conduct further studies to determine the project’s mineral reserves, which may lead to development of a heap leach operation to produce gold and silver doré at Calcatreu. The Company has ample experience with heap leach operations, having put two heap leach operations into production over the last decade.
