• The Rosita property hosts c ompelling structural lineaments, abundant geophysical

anomalies and a very prospective geological environment

VANCOUVER, BC, February 14, 2024 — Mirasol Resources Ltd. (TSX-V: MRZ) (OTC: MRZLF) (the “Company” or

“Mirasol”) is pleased to announce the signing of a landmark option agreement (the “Agreement”) with Sociedad

Química y Minera de Chile SA (“SQM”) doubling the size of the flagship Sobek Copper-Gold Project (“Sobek” or

“the Project”) in the Vicuña Copper-Gold-Silver District of northeast Chile. The SQM Property (“Rosita”) covers

11,500 hectares extending the Sobek Project to the west and to the east, and unifying the Sobek Central block

with the Sobek North block which was an important factor in this consolidation. The combined property has

doubled Mirasol’s land holding in the district for a total of 22,640 hectares. The eastern portion of the Rosita

property positions Mirasol within 3 kilometers of the giant Filo Del Sol Project and the Sobek North block is 3

kilometers from Lunahuasi discovery both within the heart of the Vicuña Copper-Gold district.

“The strategic expansion of the Sobek Project to include the sought after SQM Rosita property firmly secures

Mirasol as a key player amongst industry -leading companies in the globally recognized Vicuña Copper-Gold

district,” Mirasol’s President and CEO Tim Heenan stated. “The increase to our property size significantly

increases the exploration potential and expands Sobek further to the east, just 3 kilometers west of the Filo del

Sol Project.

Mr. Heenan added: “The Rosita field program will commence immediately with a dedicated exploration team

conducting mapping and geochemical sampling in parallel with a property wide stream sediment program to

define areas of elevated interest. Now that the agreement has been signed, Mirasol can access the Rosita

property to evaluate both AirMag and MT targets from Mirasol’s district wide proprietary geophysical database."

High-Profile Vicuña Copper-Gold-Silver District

Mirasol staked the Sobek Project in 2016 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.

The expanded Sobek Project is located on the same regional trend and just 3 km to the west of the Filo del Sol

deposit and 3 km to the southwest of NGEx Mineral’s discovery at Lunahuasi (formerly Potro Cliffs).

Sobek is located within a prospective geological environment 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 host ing several southern Andes metal deposits in both Chile and

Argentina.

The expanded and consolidated Sobek Project now comprises a large block totaling 2 2,640 ha of exploration

and mining claims in four strategic locations, the North, Central, South blocks and the Rosita Property within the

Vicuña Copper -Gold-Silver District . The high -profile district includes multiple deposits in close proximity of

Sobek, including the Filo del Sol mid-Miocene epithermal porphyry gold-copper deposit to the east; the recent

NGEx discovery at Lunahuasi (formerly Potro Cliffs) to the northeast, the Josemaria copper-gold project 10 km

to the east-northeast; the Los Helados Porphyry copper-gold breccia system 20 km to the northeast; and the

giant Eocene El Morro Porphyry copper-gold deposit 16 km to the west-southwest.

Key Terms of the Agreement:

SQM has granted Mirasol the exclusive option to earn 80% of the Rosita Project over 6 years, subject to a 2.0%

NSR royalty, by:

• Incurring US$4 million in exploration expenditures

o Year 1: US$150,000

o Year 2: US$250,000

o Year 3: US$400,000

o Year 4: US$700,000

o Year 5: US$1.0 million

o Year 6: US$1.5 million

• Making annual option fee payments for a total of US$3 million over 6 years

o At signing: US$30.000

o Year 1: US$45,000

o Year 2: US$75,000

o Year 3: US$200,000

o Year 4: US$350,000

o Year 5: US$700,000

o Year 6: US$1.6 million

Upon completion of the option, Mirasol will have earned an 80% interest in the Rosita Project and SQM will

retain a 20% interest plus a 2 % NSR. Mirasol and SQM will then form a Chilean Mining Contractual Company

covering the Rosita Project with 80% of the Shares owned by Mirasol and 20% of the Shares owned by SQM.

To discuss the importance of this landmark option agreement, Mirasol’s President and CEO, Tim Heenan, will be

hosting a Webinar on a date to be announced.
