Mirasol Advances Maiden Drill Campaign Testing Initial Targets at Flagship Sobek Copper Project in Chile

• Sobek is located 7 km directly west of Filo Mining’s Filo del Sol Project and 3 km from NGEx´s new discovery at Potro Cliffs
• 500-line kilometer Airborne Mobile MT geophysical survey completed over Sobek Central and Sobek North
• Compelling high-priority drill targets outlined by the Airborne Mobile MT survey coincident with geochemical anomalies and select high-grade surface samples
• Maiden drill campaign advances, testing first of several priority targets - two holes for a total of almost 950m completed

VANCOUVER, British Columbia, June 27, 2023 (GLOBE NEWSWIRE) -- Mirasol Resources Ltd. (TSX-V: MRZ) (OTC: MRZLF) (the “Company” or “Mirasol”) is pleased to report that the 2022/23 exploration program was successfully advanced at the Company’s 100%-owned Sobek Copper-Gold Project (“Sobek”) in the Vicuña Copper-Gold-Silver District of Chile with the completion of the airborne Mobile MT survey and the start of the maiden drill program. Sobek was originally staked based on prospective local structural architecture prior to the 2021 discovery of the high-grade feeder zone at the Filo del Sol gold-copper deposit located 7 km to the east and NGEx Minerals discovery at Potro Cliffs 3 km to the east.   

“The potential for discovery at the high-profile Vicuña Copper-Gold district has motivated us to advance Sobek from initial boots-on-the-ground exploration to the maiden drill campaign at an extraordinary pace. We will maintain this momentum and plan to continue drilling as soon as the weather allows for access in just a few months,” Mirasol’s President Tim Heenan stated. “The recently completed airborne Mobile MT survey returned multiple compelling geophysical responses coincident with geochemical anomalies and encouraging geological observations with clear evidence of advanced stage hydrothermal activity and alteration. Impressive precious and base metals results, including new multi-gram gold results from select rock grab samples at both the Sobek Central VN-Zone and Sobek North El Potro Zone elevate the importance of both target areas which will be prioritized when drilling resumes.”

High-Profile Vicuña Copper-Gold-Silver District

Sobek was staked in 2016 based on the prospective geological environment and the local structural architecture with a compelling north-northeast trending mineralized structural corridor crosscut by a north-northwest trending deep-seated trans-cordilleran lineament. This is a common structural configuration hosting several southern Andes metal deposits in both Chile and Argentina.
