Mirasol Announces Vania Drill Campaign at

Inca Copper-Gold Project in Chile

• Inca Gold is located within a “World-Class” Inca del Oro Mining District

• Airborne Mobile MT geophysical survey underway at Vania Prospects

• Drill campaign scheduled to start in July

• Compelling new targets emerging at Vania East and Vania SW

• Inca Gold and Sobek Project Update Webinar July 6 at 10 am PT / 1 pm ET

VANCOUVER, BC, June 29, 20 23 — Mirasol Resources Ltd. (TSX -V: MRZ) (OTC: MRZLF ) (the “ Company” or

“Mirasol”) is pleased to report that the 2022/23 exploration program continues to advance towards drilling at

the Vania North and Vania South prospects on the Inca Copper-Gold Project (“Inca Gold”) in Chile. Pursuant to

the Exploration Agreement with Venture Option between Mirasol and affiliates of Newmont Corporation

(“Newmont”), Mirasol has the option to earn-in 100% of Inca Gold, subject to a 1.5% NSR royalty (news release

January 13, 2020).

“Vania South and North are compelling undercover geophysical targets hosted along a major structural corridor

within this well- endowed world-class copper district. Supported by geochemical soil survey results and select

high-grade rock chip samples, the Vania South and North targets are scheduled for drilling in late July,” Mirasol’s

President, Tim Heenan, commented. “In addition , exciting new targets have been discovered with a strong

magnetic signature at Vania East, and a compelling soil survey multi-elemental geochemical anomaly at Vania

SW. A property-wide airborne mobile MT survey is currently in progress to validate and refine the existing Vania

targets for drilling and potentially identify new prospects.”

An Inca Gold and Sobek Project Update Webinar

Webinar with Tim Heenan, the Company’s President and Patrick Evans, the Executive Chair will be held on July

6th, 2023 at 10:00 am PT / 1:00 pm ET. A brief presentation will be followed by a Q&A session. Registration can

be completed using this link.

Inca Gold is a large 16,300-hectare property package located at a relatively low altitude of 2,300m (ASL) in the

Paleocene belt of Chile with year-round access and nearby infrastructure. The Vania North and South zones are

both controlled along a major north-northeast structural corridor which hosts the Inca del Oro porphyry to the

south and the expansive El Salvador mining district to the north. Vania South is located at an important

intersection of two faults, the north-south trending regional Quebrada Vasquez fault, intersecting an east-west

trending undercover interpr eted fault passing through the center of the magnetic anomaly. The Vania North

magnetic depletion response is cradled within two intersecting north -northeast and south-southwest

lineaments and hosts a strong coincident gold soil survey geochemical anomaly.

Airborne Mobile MT Geophysical Survey Initiated at Inca

Mirasol has contracted an Airborne Mobile MT survey projected to cover the entire Vania prospect at the Inca

project, including the Vania South and North prospects as well as the recently defined Vani a East and SW

prospects, with tightly spaced (100m) helicopter fl ight lines. Mirasol will also b e flying a MT survey at 200m

spaced lines over the 100% controlled Rubi Project, which is located just 20 km north of Vania. The targets at

Vania and Rubi are similar as they are both totally concealed by alluvial/colluvial transported gravel material.

Airborne Mobile MT has high-definition depth penetration to greater than 800m below the surface and has been

proven effective in defining targe ts in high -sulfidation epithermal (HSE) and porphyry systems elsewhere in

Chile. This MT survey will aid in refining high -priority targets for the upcoming maiden drill campaign focused

on Vania North and South.

Vania South and Vania North Targets

As previously reported, the reprocessing and re -interpretation of the original Newmont ground magnetic

(“Mag”) data resulted in the identification of the Vania South anomaly located 3 km south of Vania North (news

release September 7, 2022). At the Vania South target a concealed and very strong, d iscrete magnetic response

exists within the southeast corner of the Mag grid, showing smooth magnetic textures surrounding the main

anomaly ( news release December 8, 2022 ). Interpretation of the Mag data suggests that this very strong

magnetic anomaly may represent a concealed copper porphyry target, with the magnetic source potentially

characterizing the potassic-altered core of an intrusive body and the smooth magnetic border representing the

envelope of hydrothermal alteration. Coincident with the magnetic responses, strong electrical Pole-Dipole IP

geophysical anomalies are seen in the sections at both Vania North and South resulting in high -quality

geophysical drill targets.

New Emerging Vania East and Vania SW Targets

The reprocessing and re -interpretation of the original Mag data resulted in t he definition of a new previously

unknown prospective target at Vania East . In addition, reinterpretation of geochemical survey data outlined a

multi-element geochemical soil anomaly at Vania SW. Mirasol has recently completed a detailed Pole-Dipole IP

geophysical survey at Vania East, and a detailed ground magnetic survey at Vania SW. Both Vania SW and East

are localized along a strong north-northeast structural trend.
