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
Company’s 100%-owned Sobek Copper Project (“Sobek”) in Chile. Sobek
was originally staked based on prospective local 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.
“We continue to receive impressive precious and
base metals results, including multi-percentage copper, from select
rock chip grab samples at Sobek Central. This high-grade
mineralization on surface in the high-profile Vicuña Copper-Gold
district, in combination with attractive airborne magnetic
responses and very encouraging geological observations with clear
evidence of advanced stage hydrothermal activity and alteration,
continue to reinforce the potential for discovery at Sobek,”
Mirasol’s President Tim Heenan stated. “The 2022/23 exploration
campaign is advancing with follow-up exploration, the initiation of
an airborne geophysical survey and the constriction of an access
road in preparation for the maiden drill campaign at Sobek planned
for April of this year.”
High-profile Vicuña
Copper-Gold-Silver District
Sobek was staked in 2016 based on the local
structural architecture 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 hosting several southern Andes metal
deposits in both Chile and Argentina.
Sobek comprises a large block of properties
totaling 11,120 ha of exploration claims in three strategic
locations, the North, Central and South blocks. The high-profile
Vicuña Copper-Gold-Silver District is developing
in the Sobek area with multiple deposits in close proximity,
including the Filo del Sol mid-Miocene epithermal
porphyry gold-copper deposit 7 km east of Sobek; the
Josemaria copper-gold project 10 km to the
east-northeast of Sobek; the Los Helados Porphyry
copper-gold breccia system 20 km to the northeast of Sobek; and,
the giant Eocene El Morro Porphyry copper-gold
deposit 16 km to the west-southwest.

Airborne Mobile MT Geophysical Survey
Planned for Sobek
Mirasol has contracted an Airborne Mobile MT
survey projected to cover the entire Sobek Central area including
the CLP, Central Breccia and the VN zones with tightly spaced
(100m) helicopter flown lines. Airborne Mobile MT has
high-definition depth penetration to greater than 800m depth below
the surface and has been proven effective in defining targets 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 at Sobek Central.
SOBEK CENTRAL: VN-Zone Prospecting
Results
Higher grade gold results (1.04 & 1.61 g/t
gold) from recent select grab samples collected while prospecting
in the high elevation VN-Zone at Sobek Central are very
encouraging. These gold results were sourced from “Maricunga Type”
quartz-magnetite veinlets with argillized margins. The
M veinlets also contain anomalous values of copper
(700 ppm), which is typical in gold-copper “Maricunga Type”
porphyry deposits. A more detailed mapping and sampling campaign is
currently underway to better understand the significance of these
encouraging high-grade results and the geological environment and
controls on mineralization.

SOBEK CENTRAL: Green Wall Zone Extended
Further to the East-Southeast Along Trend
Results from recent select grab samples
collected at the Green Wall Zone has extended the mineralization
1,000m to the southeast towards the edge of the Central Breccia
Zone. The structure in this zone appears to narrow and is
represented by quartz stringers and centimeter scale veinlets
hosting visible green copper mineralization returning results above
1.0% copper. A new narrow “seam”, now called the Grieta Verde Zone,
further to the south of the CLP-Zone and somewhat oblique to the
Green Wall Zone, has returned encouraging copper values with highly
anomalous gold averaging 0.25 g/t gold from the 10 select grab
samples collected from this area. This narrow “seam” injected into
the hosting sediments is similar to that seen in the Green Wall
Zone, which is also hosted in the sediments on the north side of
the CLP-Zone. At Grieta Verde, the copper mineralization is also
present in the hosting sedimentary conglomerates and appears to
have been concentrated in and around the clasts within the
sediments. While neither of these zones represent potential
stand-alone targets, the high-grade copper values with associated
gold within the hydrothermal system is potentially sourced from a
larger concealed body under either the CLP or the Central Breccia
zones, which will be the focus of the maiden drill campaign.
SOBEK CENTRAL: Expansion of Polymetallic
Soil Anomaly
The Sobek Central soil sampling grid was
expanded to infill and increase the coverage 450m to the southeast
of the Central Breccia Zone. The expansion and infill of the soil
grid shows a clear extension of the Central Breccia polymetallic
soil anomaly to the southeast and appears to highlight a copper
halo around the main breccia body with a strong lead/zinc anomaly
directly above it (see figure 3). Another widespread copper soil
anomaly appears to be emerging to the southeast of the Central
Breccia Zone beyond a 250m “quiet” zone. This copper soil anomaly
is emerging with some continuity, coincident with smaller areas of
anomalous lead, zinc, silver and gold. Sampling crews will be
continuing to advance the soil grid further to the southeast and on
to the south to cover the area which host the gold-bearing veins at
the VN-Zone.

Multi-element Coincident Geochemical Soil Anomaly
SOBEK NORTH: El Potro
Prospect
The El Potro Zone at Sobek North is located
approximately 5 km directly west of the NGEX Potro
Cliffs project in Argentina. The newly encountered areas
of interest within the El Porto Zone host a system of veins and
veinlets of pyritic bearing quartz veins with Chrysocolla
(copper-silicate). Exploration crews are currently mapping and
prospecting the area and the first batch of samples are with ALS
laboratory for analysis.
Preliminary geological observations are highly
encouraging and suggest the presence of large Paleocene aged
granitic bodies cut by what appears to be younger intrusives
(Mio-Pliocene) of Syenitic and Monzonitic composition hosting fine
sulphides forming “clots” within the matrix. Aphanitic intermediate
pyritic dykes also cut the granites in a northeast direction, and
host fine sulphide-rich veinlets with copper oxides cutting the
dykes at a perpendicular angle. In addition, sub-angular float
blocks within the creek beds contain molybdenite and traces of
chalcopyrite hosted within what appear to be the younger intrusive
rocks. The source of these floats is currently being investigated.
The El Potro access road is scheduled for rehabilitation once the
Sobek Central access road has been completed to allow vehicle
access to the higher elevations of the El Potro prospect.

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 chip, soil, and stream sediment samples are
collected under the supervision of the company’s geologists in
accordance with industry practice. Geochemical assays are obtained
and reported under a quality assurance and quality control (QA/QC)
program with 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. Assay results from
rock chip, soil stream sediment, 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 in the primary
mineralization.
