VANCOUVER, British Columbia, June 16, 2025 (GLOBE NEWSWIRE) -- Mirasol Resources Ltd. (TSX-V: MRZ) (OTC: MRZLF) (the "Company" or "Mirasol") is pleased to report the signing of a Memorandum of Understanding ("MOU") under which Mirasol grants Ampere Metals Pty. Ltd. ("Ampere Metals") an exclusive right to enter into a definitive agreement (the "Definitive Agreement") to acquire the mineral rights and landholdings within Mirasol's 100% owned Virginia Silver Project ("Virginia" or the "Deposit") located in the Santa Cruz Province, Argentina.

Discovered by Mirasol in 2009, Virginia hosts a high-grade, intermediate sulfidation epithermal style mineralization in a series of prominent outcropping vein-breccias. An updated Resource Estimate (the "Resource") is contained within a series of nine outcropping veins hosting high-grade silver mineralization, constrained within conceptual pits, with an indicated mineral resource of 11.7 million ounces of silver at 357 g/t silver and a further inferred mineral resource of 7.9 million ounces of silver at 184 g/t silver (news release November 9, 2023).

"The sale of our Virginia Silver Project represents the first major achievement of our ongoing business development initiative and demonstrates the potential of our highly prospective, yet undervalued, portfolio of projects in Argentina and Chile," Mirasol's President Tim Heenan stated. "The payments of US$8 million over the next five years will contribute to our ongoing exploration on our flagship Sobek Project and the remaining royalty will create significant value to Mirasol shareholders as the Resource at Virginia continue to expand."
