Mirasol Signs a Binding Letter Agreement with Newcrest Mining for

Gorbea Gold Project JV in Chile

VANCOUVER, BC, January 28, 2019 — Mirasol Resources Ltd. (TSX-V: MRZ, OTCPK: MRZLF ) (the “Company” or

“Mirasol”) is pleased to report the signing of binding letter agreement (the “ Agreement”) with Newcrest

International Pty Limited, a wholly owned subsidiary of Newcrest Mining Limited (ASX:NCM)(“NCM”), for an

Option to Farm-in on the Gorbea High-Sulfidation Epithermal (HSE) gold projects (the “Project”) in Chile (Figure

1).

Mirasol’s CEO Stephen Nano stated : “Newcrest is the ideal partner for our Gorbea projects. Subject to drill

permitting, Newcrest will this year fund drill testing of two, large Mio-Pliocene belt HSE Au+Ag projects at Gorbea

and under a separate agreement, at the Altazor project in northern Chile”.

The Gorbea Agreement comprises a package of projects totaling 26,684 ha, including the Atlas Au+Ag and the

Titan Au (Cu) lead properties, located in the Mio-Pliocene age mineral belt of northern Chile. NCM has the right

to acquire , in multiple stages, up to 75% of the Gorbea Project by completing a series of exploration and

development milestones and making staged option payments to Mirasol. NCM has committed to spend a

minimum of US$ 4 million and to complet e a minimum of 3,000 m of drilling over an initial 18 -month period.

NCM will operate the exploration program at Gorbea.

NCM and Mirasol are working collaboratively to advance the drill permitting process at Gorbea and upgrade the

exploration camp ahead of the planned Q1 2019 restart of the exploration program that will initially focus on the

Atlas project, including detailed re-mapping, alteration vectoring studies, 60 line-km of CSAMT geophysics, and

diamond core drilling.

Terms of the Agreement

Option phase:

• US$100,000 cash payment upon signing the Agreement;

• NCM’s minimum commitment is to spend US$ 4 million and drill a minimum of 3 ,000m in the first 18

months of the exploration program;

• NCM will operate the Project and will receive a 5% management fee; and

• At the end of the Option phase, NCM will have the right to exercise the Farm-in phase of the Agreement.

Farm-in phase:

• Stage 1: NCM will make a cash payment to Mirasol of US$ 500,000, and will have the right to earn 51%

of the Project over a 4.5-year period (total 6 years) by spending an additional US$15 million (total US$19

million), which includes a minimum drilling commitment of 6,000 m to be completed within the first 2

years;

• Stage 2: If NCM elects to proceed to Stage 2 of the Farm-in, it will make a cash payment to Mirasol of

US$650,000 and have the right to earn 65% of the Project over an additional 1-year period (total 7 years),

by funding the delivery of a positive preliminary economic assessment, in accordance with NI 43-101, on

a resource of not less than 1 million ounces of gold at a cut-off grade of 0.30 grams per tonne (g/t);

• Stage 3: If NCM elects to proceed to Stage 3 of the Farm-in, it will have the right to earn 75% of the

Project over an additional 2 -year period (total 9 year s) by funding the lesser of either: (i) additional

expenditures of US$100 million; or (ii) the delivery of a positive bankable1 Feasibility Study, in accordance

with NI 43-101;

• Stage 4: After completion of Stage 3, Mirasol can elect to: (i ) contribute its proportionate 25% share of

further development expenditures, (ii) exercise a one -time equity conversion option to convert up to

10% of its equity into a NSR royalty at a rate of 2.5% equity per 0.5% NSR royalty (max 2% NSR royalty)

and then contribute funding to advance the Company’s remaining Project equity interest; or (iii) dilute.

The rate of royalty dilution (up to 2% and triggered upon dilution of its interest to 10%) will be adjusted

based on the percentage royalty acquired as part of the equity conversion option. NCM will hold a 0.5%

NSR buyback right at fair market value exercisable on the conversion royalty or the dilution royalty.

After meeting the minimum commitment in the Option phase, NCM may terminate the Agreement at any time

without liability. In the event that NCM should complete Stage 1, but elect not to proceed to Stage 2, NCM’s 51%

interest shall be adjusted to a 49% interest. If NCM completes Stage 2, but elects not to proceed to Stage 3, the

65% interest shall be adjusted to 60% and the parties may agree to halt further exploration or continue and

contribute in proportion to their interests or be diluted.

The Agreement also contains other customary terms, including extension rights to increase the duration of each

stage in return for cash payments to Mirasol, and pre-emptive rights provisions should either party elect to sell

its interest in the Project.

The Gorbea Project

The Gorbea Project comprises a package of nine projects totaling 26,684 ha, including the Atlas Au+Ag and the

Titan Au (Cu) projects, located in the Mio -Pliocene age mineral belt of northern Chile. Mirasol has completed

and reported (news release January 7, 2018) the results of an integrated analysis of the extensive Atlas database

generated from exploration expenditures in excess of US$ 8 million completed under a prior joint venture

agreement. The previous exploration identified a significant body of HSE gold mineralization at the Atlas project,

which returned a drill intercept of 114 m grading 1.07 g/t Au, including 36 m grading 2.49 g/t Au (news release

September 11, 2017 ). However, t he scale of the Atlas Au+Ag system, combined with the relatively modes t

amount of exploration drilling to date (10,499 m in 26 holes) and the range of priority targets identified, highlights

the Project as a large, under-explored HSE system, requiring further drill testing for potential large tonnage bulk

minable Au+Ag mineralization.

Under the terms of the pervious Gorbea Joint Venture (terminated in April 2018), all exploration was managed by the then

joint venture partner. Pre-joint venture exploration on the projects was managed by Stephen C. Nano, who is the Qualified

Person under NI 43-101. Exploration data generated from the previous Gorbea Joint Venture program was reviewed and

validated by Mirasol prior to release. The technical interpretations presented here are those of Mirasol Resources Ltd.

Mirasol applies industry stand ard exploration sampling methodologies and techniques. All geochemical rock and drill

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. Samples are dispatched

to an ISO 9001:2008 accredited laboratory in Chile for analysis. Assay results from surface rock, channel, trench, and drill

core samples may be higher, lower or similar to results obta ined from surface samples due to surficial oxidation and

enrichment processes or due to natural geological grade variations in the primary mineralization.
