Mirasol Commences 2,500 m Drilling campaign at La Curva, Santa Cruz,

Argentina

VANCOUVER, BC – October 26, 2017 -- Mirasol Resourc es Ltd. (TSX-V: MRZ, OTCPK: MRZLF, “Mirasol”) is

pleased to announce the start of a 2,500 meter diam ond core drilling program at its La Curva Joint Ven ture

Project (“Project”) with OceanaGold Corporation (OGC), Santa Cruz Province Argentina.

La Curva is a 100% Mirasol owned, 36,100 ha exploration-stage gold project located at low elevation in an area

with favorable infrastructure ion the western side of Santa Cruz province. Mirasol’s exploration at th e Project

has outlined three gold prospects at Cerro Chato, L oma Arthur and SouthWest, situated along the six km long

“La Castora” Trend. These represent compelling dril l targets for bulk mineable or high grade, low sulf idation

epithermal gold and silver mineralization ( Figure 1). This style of mineralization is typical of several multi-million

ounce gold – silver mines in the province that are operated by multinational mining companies.

Mirasol recently announced (see new release May 25, 2017) a Joint Venture (JV) at La Curva with high m argin

precious metal miner OceanaGold Corporation (OGC). The JV requires OGC to make a first year exploration spend

of US$1.25 million and to drill 3,000 metres at the project. OGC can elect to earn up to 75% of the L a Curva

project by making staged option payments to Mirasol totaling US$1.5 million, delivering a feasibility study, a

decision to mine, and by providing mine finance to Mirasol for it 25% retained project equity. Mirasol is the

Project operator for the first year of the JV.

Mirasol has previously reported on the La Curva Pro ject where the Company’s exploration has led to the

discovery of wide-spread, undrilled precious metal mineralization. The three drill-ready prospects at Cerro

Chato, Loma Arthur and SouthWest are characterized by coincident large-scale outcropping alteration, I P

geophysical anomalies, and anomalous rock chip assays ranging up to 66.8 g/t Au. This drill program is planned

to deliver an initial shallow, 17 hole test of the Castora Trend targets (Learn more about the La Curva Drill targets ).

A series of early-stage prospects have also been identified at the Project in the Curva West prospect where rock

chip anomalies ranging up to 20.73 g/t Au and 153.6 g/t Ag are found in a prospective geological setting. Mirasol

and OGC are advancing exploration of this mineralization to define drill targets to be tested during subsequent

drill campaigns.

Mirasol looks forward to updating its shareholders on results from the current drill program at La Cur va which

are anticipated during the fourth quarter of 2017.

Quality Assurance/Quality Control of the La Curva exploration program:

All exploration on the project was supervised by Mirasol CEO Stephen C. Nano, who is the Qualified Person under NI 43-101.

Mirasol is operating applies industry standard expl oration sampling methodologies and techniques. All geochemical rock

and drill samples are collected under the supervisi on of the company’s geologists in accordance with i ndustry practice.

Geochemical assays are obtained and reported under a quality assurance and quality control (QA/QC) pro gram. Samples

are dispatched to an ISO 9001:2008 accredited laboratory in Argentina for analysis. Assay results from surface rock, channel,

trench, and drill core samples may be higher, lower or similar to results obtained from surface sample s due to surficial

oxidation and enrichment processes or due to natural geological grade variations in 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 state ments. Factors that could cause such differences in clude: changes in

world commodity markets, equity markets, costs and supply of materials relevant to the mining industry , change in

government and changes to regulations affecting the mining industry. Forward-looking statements in thi s release include

statements regarding future exploration programs, o peration plans, geological interpretations, mineral tenure issues and

mineral recovery processes. Although we believe the expectations reflected in our forward-looking stat ements are

reasonable, results may vary, and we cannot guarant ee future results, levels of activity, performance or achievements.

Mirasol disclaims any obligations to update or revi se any forward-looking statements whether as a resu lt of new
