Mirasol Refines Priority Targets Based on Results from Preliminary Drill Program at 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 Lunahuasi
• Initial drill campaign cut short with only two targets partially tested, both require follow-up drilling
• Several compelling high-priority drill targets remain to be tested outlined by the Airborne Mobile MT survey coincident with geochemical anomalies and select high-grade surface samples
• Drill program to resume in early October when spring weather returns
• Planning for 3,400 meters of drilling distributed between Sobek Central and Sobek North (El Potro)
  

VANCOUVER, British Columbia, Aug. 21, 2023 (GLOBE NEWSWIRE) -- Mirasol Resources Ltd. (TSX-V: MRZ) (OTC: MRZLF) (the “Company” or “Mirasol”) reports that results from the preliminary drill program at the Company’s 100%-owned Sobek Copper-Gold Project (“Sobek”) in the Vicuña Copper-Gold-Silver District of Chile were inconclusive as the first drill holes did not reach the desired targets. Drilling was suspended with the onset of winter weather in the high Andes. The drill program was initiated late in the season when road construction allowed access for the drill rig (see news release dated June 27, 2023). The initial targets will require follow-up drilling and several other priority targets will also be drill tested when the campaign resumes in Q4 2023.

Sobek was originally staked by Mirasol based on prospective local geology and attractive 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 Lunahuasi (formerly Potro Cliffs) 3 km to the east.

“Mirasol is the only junior exploration company actively drilling in the middle of the high-profile Vicuña Copper-Gold district in northeast Chile where extraordinary discoveries continue to be made. In the interest of safety, our maiden drill campaign was suspended due to the onset of winter weather before we could adequately test our first targets. However, these early results have provided some important structural data which will help to refine our drill plans,” Mirasol’s President Tim Heenan stated. “We have only just started to scratch the surface at Sobek and high-priority targets of massive scale remain to be drill tested. We are excited to resume drilling in just a couple of months as soon as the weather allows for access.”
