Mirasol Announces the Launch of Partner-Funded Drill

Program at the Claudia Gold-Silver Project in Argentina

• Claudia Project located directly south of Cerro Vanguardia Mine: 15 kilometers from

the mill

• Initial drill program of 3,300 meters currently underway

• Southern most veins on the Cerro Vanguardia property trend onto Claudia Property

• Five distinct, highly prospective vein trends within the very large Claudia Property

• Minimum of 2 ,500 meters of drilling within the first 24 months and the option to

complete 12,500 meters of drilling within 4 years

• Mirasol retains 2% NSR Royalty upon the exercise of the Option

VANCOUVER, BC, October 3, 2023 — Mirasol Resources Ltd. (TSX -V: MRZ) (OTC: MRZLF ) (the “ Company” or

“Mirasol”) is pleased to announce that its partner , the Cerro Vanguardia SA Gold-Silver Mine (“CVSA Mine”)

owned by AngloGold Ashanti (92.5%) and FOMICRUZ S.E. (7.5%), has initiated a drill program at the Claudia

Gold-Silver Project (“Claudia”), located directly south of the CVSA Gold-Silver Mine in the province of Santa Cruz,

Argentina.

The extensive 65,192-hectare Claudia Gold-Silver Project is a highly prospective low sulphidation epithermal

(LSE) gold/silver project, located in the Deseado Massif of Argentina’s Santa Cruz province, directly adjacent to

the southern border of the producing CVSA Mine. Under an Option Agreement, CVSA has the right to acquire a

100 percent interest in Claudia by completing 12,500 meters of diamond drilling within four years. If the Option

is exercised, Mirasol will retain a 2% Net Smelter Royalty on future production from the Claudia Project (news

release May 23, 2023).

In this first phase of drilling, o ver 3,300 meters of drilling will be completed in 13 holes ranging from 100 to

>400m in depth to test the prospective vein trends which are potentially southern extensions and/or parallel

trends of the CVSA Mine vein field.

“The accelerated pace of drilling at Claudia demonstrates the importance of defining potential additional mill-

feed within close proximity to the nearby CVSA Mine”, Mirasol’s President Tim Heenan stated. “This could offer

significant near-term value to Mirasol shareholders through the retained 2% net smelter royalty.”

Five distinct prospective vein trends have been identified at Claudia including the Curahue Vein Field and the Rio

Seco Prospect. In 2012, Mirasol discovered the large northwest trending 15-kilometer long Curahue vein field,

which may be considered a southern parallel structure, similar to the controlling structures further north at the

Cerro Vanguardia vein field. Curahue hosts six isolated vein segments. Claudia also hosts two paleo -surface

expressions of “sinter fields” at both Calandria and Rio Seco. These sinters are considered attractive targets as

any mineralized structure found beneath would be completely preserved and not reduced by erosion. Neither

of these sinter occurrences have been drilled to date. The exploration potential of the Claudia Project ,

particularly along the largely untested Curahue and Rio Seco trends, shows clear potential for Vanguardia-style

vein-hosted epithermal gold-silver mineralization.

Homenaje Gold-Silver Project in Argentina

Mirasol today also announces that the option agreement on the Homenaje Gold-Silver Project in Argentina

(“Homenaje”) with Patagonia Gold Corp. (“Patagonia”) has been terminated. Patagonia failed to complete the

contractual minimum obligations on exploration during the term of the option agreement ( news release dated

April 19, 2021). With 100% interest in Homenaje , Mirasol is evaluating options to advance exploration at

Homenaje.
