Mirasol Reports Results from Drilling Program at its Gorbea Project
in Northern Chile
VANCOUVER, BC, April 22, 2020 — Mirasol Resources Ltd. (TSX -V: MRZ) (OTCPK: MRZLF) (the “ Company” or
“Mirasol”) is pleased to report the final assay results from the drilling program completed by Newcrest Mining
Limited (ASX: NCM) (“Newcrest”), at its Gorbea Gold project located in Northern Chile, under an option and farm-
in agreement (see news release January 28, 201 9). Over the course of this campaign, Newcrest completed
4,523m of diamond drilling, for a total of 5,426m since the beginning of the exploration partnership. Newcrest
has also reported exploration expenditures of approximately US$ 8.6 million on the property to the end of March
2020, representing a significant investment on the project.
The best assay results from this phase of drilling came from the final drill hole of the program:
ATL-DDH-010: 0.54 g/t Au and 2.65 g/t Ag over 129m (from 363m), including :
• 1.4 g/t Au and 2.08 g/t Ag over 17m (from 364m), also including :
o 2.09 g/t Au and 3.00 g/t Ag over 10m (from 371m)
• 1.84 g/t Au and 3.57 g/t Ag over 3m (from 425m)
As reported on March 19, 2020, exploration activities were suspended at the site as a safety precaution due to
the COVID-19 pandemic. Newcrest and Mirasol have agreed to extend the option period by 6 months to
January 25, 2021 and Newcrest has committed to drilling at least 2,000m at the project over the upcoming
season.
Norm Pitcher, President and CEO of Mirasol stated: “While it was disappointing that the drill program ended
prematurely, we are pleased that we were able to reach an agreement to extend the option period with a n
additional drill commitment which will allow Newcrest to continue exploring at Gorbea. Newcrest’s latest drilling
in the central breccia complex continues to hit long intervals of mineralization with localized higher-grade zones.
Mirasol and Newcrest will work together to vector toward these higher -grade areas and to define additional
quality regional targets. There are still a number of untested areas at Atlas as well as at the other five selected
prospects in the Gorbea package.”
Atlas Target Update
o General Overview
The latest round of drilling on the Atlas target, which is a large high sul fidation epithermal (HSE) system
outcropping over 20 km2, brings the total drilling to 15,925m in 35 holes by both Newcrest and a previous partner
and demonstrates widespread mineralization within the central breccia complex. Results to date suggest that
the Atlas HSE system is comparable in aerial extent to other economic systems in the area, such as Salares Norte
(Gold Fields), Alturas (Barrick Gold) and La Coipa (Kinross Gold). Additionally, lithochemical studies on drill
samples indicate that the geochemical footprint of the system, which appears to NW and NE show structural
controls, is larger than the area covered by the drilling to date and is open to the north, east and southwest.
Figure 1: Atlas Project – Plan Map
Mineralization is associated with phreatomagmatic and hydrothermal breccias and intensely advanced argillically
altered porphyritic andesite, often where a vuggy silica texture has developed. The area has been deeply oxidized
to depths of over 400m, which is potentially advantageous for the development of favorable metallurgy.
Initial wide spaced drilling has been important to test the large size of the system and distribution of favorable
outcropping breccia targets. Future efforts to define higher grade zones will now be guided by targeting resistive
units identified by CSAMT geophysics along with structural mapping, geochemistry, and vectors to feeder zones
from alteration zonation and alunite composition.

Mirasol continues to work closely with Newcrest to better understand the controls on th e higher-grade
mineralization and to collaborate in the definition of quality targets for future drilling , which is scheduled to
restart in the southern hemisphere spring season of 2020. In addition, Newcrest intends to drill-test the El
Dorado prospect as well as continue field evaluation work at selected regional prospects (Ventura, Sirio, Orion
and Titan).
o Drilling Results:
This news release reports on a total of 2,449.5m from five holes (ATL-DDH-06 to ATL-DDH-10). Three of these
holes (ATL -DDH-006, 007 and 009) are wide step -out holes testing targets 1 -2 km from the known central
mineralized area and two (ATL-DDH-008 and 010) were drilled to test continuity within and to the south of the
main mineralized zone.
Figure 2: Atlas Project - Cross Section Central Breccia Complex
Hole ATL-DDH-010 intersected a broad zone of mineralization over a width of 1 28.8 m starting at 3 63m down
hole, including 17m at 1.4 g/t Au (364-381m), also including 10 m of 2.09 g/t Au (371-381m). This suggests the
continuity of the mineralized zone for over 300m between the previous intersections in holes CLATDH0015 and
ATL-DDH-001A. The mineralization occurs in strongly altered porphyritic andesites and hydrothermal breccias
with vuggy silica textures, strong silicification and quartz alunite alteration.
Hole ATL-DDH-009 targeted an area of intense advanced argillic (quartz alunite) alteration and high gold values
(to 50 g/t Au) exposed in trenching, 1.3 km to the NW of the central mineralized zone. Despite local intervals of
vuggy silica textures at a similar depth (200m) to the central zone, along with quartz alunite alteration, the hole
appears to have intersected a peripheral zone with multiple short intervals of 3m at 0.64 g/t Au from 85m and
3m at 0.32 g/t from 284m.
Hole ATL-DDH-008 was drilled southwards along a trend of high resistivity, stepping out 200m south from ATL -
DDH-004. No significant gold intervals were intersected, but sporadic values of 1m at 1.08 g/t Au, 0.24 g/t Au,
and 0.2 g/t Au along with anomalous Ag, Pb and As ge ochemistry suggests that the setting may be marginal to
the source.
Hole ATL-DDH-007 was drilled 2 km SE of the central mineralized zone to test a resistor in an area of mapped
polymictic breccia and below outcropping steam -heated alteration. I t intersected andesite and polymictic
breccia, with advanced argillic alteration including pyrophyllite and alunite with a composition that may indicate
proximity to higher temperature feeder zones.
Hole ATL-DDH-006 was drilled as a step-out to the east of known mineralization and was terminated in a sterile
late to post mineralization porphyritic daci-andesite porphyry.
