en.Wedoany.com Reported - Patagonia Gold has produced and shipped the first doré bars from its Calcatreu project in Río Negro Province, Argentina, marking the mine's official entry into the metal recovery phase. The initial shipment, totaling 518 ounces of gold equivalent, has been delivered to Asahi Refining Ltd. The metal was sourced from the heap leach circuit, which began operations on April 15 and is a critical component of the project's startup.

Since the commencement of heap leaching, the company has completed metallurgical recovery and processing stages, culminating in the casting of the first doré bars. Technical teams continue to monitor the performance of the heap leach pad, solution flow rates, and recovery rates during the ramp-up period. Based on currently published resources, the Calcatreu deposit contains 669,000 ounces of gold and 6.27 million ounces of silver in the indicated resource category, with an additional 348,000 ounces of gold and 3.39 million ounces of silver in inferred resources. The company is updating its resource estimate, with new data expected to be released in the second quarter of 2026.

The project's operation is a landmark for Río Negro Province, as it is the first precious metals mining and processing project to enter production in the province. With the initial metal shipment and ongoing ramp-up, Calcatreu is gradually becoming a new source of gold and silver production in Argentina's mining sector, while also placing Río Negro Province on the country's metal mining map.
