(TSX-V: MRZ) (OTC: MRZLF) (the “Company” or “Mirasol”) is pleased to announce that results from the second drill hole at the Potro SE target extends the structurally controlled mineralized hydrothermal breccia system with gold, silver, zinc and lead and indications of copper on the Company’s 100%-owned Sobek Copper-Gold Project (“Sobek” or “the Project”) in the Vicuña District of Chile. Located at the southeast corner of the Sobek North property block, the Potro SE target is strategically situated just 3km southwest of NGEx’s Lunahuasi discovery in an area that had not previously been drill tested. Building on the success of the first hole at Potro SE, the second drill hole was positioned 200m northeast along the fault structure to test the strongest response of the cylindrical 3D magnetic anomaly and penetrate deeper into the IP PDP chargeability responses (news release dated Mar 2, 2025).
