Mirasol Resources Identifies New Copper Porphyry Target on its
Tefnut Prospect in the Province of San Juan, Argentina
VANCOUVER, BC, June 9 , 20 22 — Mirasol Resources Ltd. (TSX -V: MRZ) (OTCPK: MRZLF ) (the
“Company” or “Mirasol”) is pleased to report the exploration results from its 100% controlled Tefnut
copper prospect (“Tefnut”), located within the fertile Mio-Pliocene copper-belt in the province of San
Juan, Argentina. The province of San Juan hosts several high-profile advanced projects including Filo del
Sol, Josemaria, Altar, Los Azules and El Pachon. Tefnut, staked by Mirasol through its project generation
program, comprises approximately 4,500 hectares of exploration claims . The Company’s preliminary
reconnaissance program of prospecting, high level geological mapping, geochemical sampling and
alteration analysis, successfully defined a large 1.5 by 1.5 kilometres porphyry related phyllic alteration
system with outcropping copper-mineralization.
“We are very excited to introduce a new high -quality porphyry copper target within the renowned
province of San Juan, ” Mirasol’s President, Tim Heenan, commented . “Our first boots on the ground
reconnaissance over this completely untested area has identified a sizeable new alteration at Tefnut
that we will continue to advance to drill testing.”
Tefnut is located at the intersection of a major orogenic parallel NS structure and a lesser defined NNW
trans-orogenic lineament which is the common structural configuration that has localized other major
deposits and development projects in the province of San Juan. In close proximity to the west and in
Chile, advanced projects like Novicio, West Wall and Pimenton represent good analogies for the
prospectivity of the immediate area.

Within the large 1.5 x 1.5 kilometre intensely altered phyllic footprint at Tefnut, discrete outcropping
exposures of porphyry -style copper-mineralization occur in the deeply incised creeks. This
mineralization is associated with high density stockworks of quartz magnetite and fine magnetite only
stringers, w ithin strongly potassic alter ed ( biotite-feldspar-magnetite) intrusive dioritic porphyry
hosting disseminated chalcopyrite and Cu-oxides. Initial grab samples from these mineralized outcrops
have returned 0.14% and 0.19% copper. In addition, anomalous molybdenum values of 42 ppm hosted
in type B veinlets, with the four highest values (from a population of 15) ranging from 17-42 ppm, were
recovered from the overlying rhyolites that exhibit intense phyllic alteration.
These initial geological and geochemical results indicate the presence of an underexplore d and
potentially substantive porphyry copper -molybdenum system. P otassically altered dioritic intrusive
rocks, hosting disseminated copper mineralization, are exposed in discrete erosional windows through
an extensive area of phyllic alteration with local remnant advanced argillic altered sections. It is

considered that Tefnut has been eroded to a n optimal level for the exploration with the prospective
copper mineralized potassic zone preserved at shallow levels and extending to depth.

Given the encouraging results from the initial reconnaissance campaign at Tefnut, Mirasol is planning
to progress its exploration efforts during the upcoming southern hemisphere exploration season
(October 2022 - April 2023). Detailed grid based geochemical sampling, geological/structural mapping
and geophysical surveys will be required to advance this new and exciting prospect to a drill ready stage.

Qualified Person Statement: Mirasol’s disclosure of technical and scientific information in this press release has been
reviewed and approved by Tim Heenan (MAIG), the President for the Company, who serves as a Qualified Person under the
definition of National Instrument 43-101.
QAQC: Mirasol applies industry standard exploration sampling methodologies and techniques. All geochemical rock samples
are collected under the supervision of the company’s geologists in accordance with industry practice. Geochemica l assays
are obtained and reported under a quality assurance and quality control (QA/QC) program w ith insertions of controls
(standards, blanks and duplicates ) submitted to the laboratory . Samples were dispatched to ALS Global - Geochemistry
Analytical Lab, in Santiago, Chile, an ISO 9001:2015 accredited laboratory, which is independent from the Company . Rock
chip samples (1-3kg) were prepared with PREP31, and analysed by Au_ICP21 and ME-MS61. The soil samples were prepared
with PUL-31, analysed by Au_ICP21 and ME-MS61. The Stream Sediment, mesh (1kg) samples were prepared by SCR -51#-
80, analysed by ME-MS41L. BLEG (>2kg) is the Bulk Leach Extractable Gold using a cyanide-based bottle roll technique with
an AA finish. Assay results from channel, trench, and drill core samples may be higher, lower or similar to results obtained
from surface samples due to surficial oxidation and enrichment processes or due to natural geological grade variations i n
the primary mineralization.
Forward Looking Statements: The information in this news release contains forward looking statements that are subject to
a number of known and unknown risks, uncertainties and other factors that may cause actual results to differ materially
from those anticipated in our forward -looking statements. Factors that could cause such differences include: changes in
