Mirasol Resources Introduces Nandi Copper Project in Chile

• Prospective Cu/Mo/Au generative project

• Proximal to world-class Escondida and Lomas Bayas Cu Mines

• Encouraging early exploration results

• Low altitude and excellent access

VANCOUVER, BC, November 5, 2020 — Mirasol Resources Ltd. (TSX-V: MRZ) (OTCPK: MRZLF) (the “Company”

or “Mirasol”) is pleased to report initial exploration results from its 100% owned Nandi Cu project, located in the

Paleocene porphyry Cu belt in northern Chile. Nandi was staked by Mirasol through it s project generation

program and comprises approximately 5,000 ha of exploration claims , located 30 km northwest of BHP’s

Escondida Cu mine and 63 km southeast of Glencore’s Lomas Bayas Cu mine.

Mirasol’s Chair and Interim CEO, Patrick Evans commented: “Nandi represents an attractive project with multiple

targets to be drill tested. It is hosted in a productive p orphyry belt in proximity to two world-class Cu mines.

Results f rom Mirasol’s initial exploration work indicates that Nandi has the potential to host a concealed

Cu/Mo/Au porphyry deposit, and skarn type mineralization. The team is currently assessing options to further

advance exploration at Nandi.”

Geologically, Nandi is favorably situated in the area of intersection between the continental-scale north-south

trending Domeyko Fault System and the northwest trending Archibarca Lineament , a regional structural

framework that, for example, controlled the emplacement of the giant Escondida porphyry Cu deposit cluster.

The project also benefits from easy access along the asphalt highway from the port city of Antofagasta to the

Escondida mine, lying at a relatively low altitude of 1,800m above sea level.

To date, Mirasol has completed first-pass reconnaissance and exploration programs, including:

• Reconnaissance scale lithological and alteration mapping supported by spectral mineralogy analyses of

rock samples;

• Geochemical stream sediment and rock chip sampling;

• Focused geochemical channel sampling from nine historical trenches; and

• Soil geochemical sampling on a 100 x 200m grid at the Border Zone target.

The results of these initial surveys have delineated multiple exploration targets for detailed follow up.

The Border Zone target, located in the northeast area of the Nandi project, has the potential to host porphyry

Au/Cu style mineralization. Cretaceous andesites and volcanic breccias host a series of multiple phases of

intrusive and hydrothermal events, which notably include a quartz porphyritic rhyodacite intrusive body that is

cut by black banded quartz veins (BBV) and a phreatic breccia with banded quartz veined clasts. BBV veining is

typically found in porphyry Au deposits of the Maricunga Belt such as the Marte deposit (Indicated Resources:

33.47 Mt at 1.58 g/t Au1). Anomalous Au includes assay values ranging from 0.1 to 2.6 g/t Au in rock chip samples

(out of 65 samples, 8 samples returned over 0.1 g/t Au and 2 samples over 1 g/t Au), as well as 7 samples with

values of 15 to 40 ppb Au from a soil grid completed over the Border Zone target. In addition, anomalous Cu

values ranging from 100 to 4,850 ppm in rock chip samples were recovered in this zone (out of 65 samples, 7

samples returned above 200 ppm Cu).

The Central Zone target is located some 4 km west-southwest from the Border Zone target in the center of the

tenure. It is characterized at surface by thin horizons of Pb-Zn stratiform mineralization with traces of secondary

Cu oxides hosted by Jurassic silty dolomites. This mineralization may possibly be related to the intrusion of dykes

of Paleocene quartz diorite and rhyolite quartz porphyry exposed in the historical trenching. Disseminated and

also northwest fracture-controlled goethite and jarosite (1-3% by volume ) could have formed from pyritic

mineralization peripheral to a larger intrusive either at depth directly below the Central Zone, or under the gravel

cover of the Pampa Zone directly to the north. In regard to the latter, there is a discrete, sizable magnetic low

some 2 km in diameter, which could present a porphyry Cu target.

Initial exploration results have been encouraging and highlight the potential for porphyry Cu mineralization

which merits follow up field work including geophysical surveys, to define targets for drill testing.
