Mirasol Signs a Binding Letter Agreement with Newcrest Mining for a Joint

Venture on the Zeus Gold Project in Chile

VANCOUVER, BC, February 26, 2018 — Mirasol Resources Ltd. (TSX-V: MRZ, OTCPK: MRZLF ) (the “Company”

or “Mirasol”) is pleased to announce that it has signed a binding letter agreement (the “ Agreement”) for the

Company’s 18,480 ha Zeus High-Sulfidation Epithermal (HSE) gold project in Chile , with Newcrest International

Pty Limited, a wholly owned subsidiary of Newcrest Mining Limited (ASX: NCM). NCM has the right to acquire,

in multiple stages, up to 80% of the Zeus Project by completing a series of exploration and development

milestones and making staged option payments to Mirasol of US$1 million. NCM will spend a minimum of US$1.5

million at Zeus over a n initial 18-month period, and has also agreed to fund costs arising from an option to

purchase agreement (see new release January 16th 2018) entered into by Mirasol with the underlying owner of

a 2,500 ha portion of 3rd party claims at Zeus.

NCM is one of the world’s largest gold mining companies, operating five mines in Australia, the Asia - Pacific and

Africa regions. NCM has extensive experience developing and operating successful mines in culturally and

geographically diverse environments. NCM seeks to identify and secure large mineral districts, or provinces, in

order to establish long term mining operations.

Stephen Nano, CEO of Mirasol, stated that “we are very pleased to be partnering with Newcrest to explore and

advance Zeus. This is Newcrest’s second farm in agreement with Mirasol within six-months, which along with

Mirasol’s existing Altazor Agreement with Newcrest, and the Yamana Gold Gorbea JV, establishes the Company

as a leading explorer in the prospective Mio-Pliocene gold and copper belt of Chile (figure 1). Mirasol’s ability to

work quickly with Newcrest to reach this Agreement will now allow us to advance a large -scope surface

geological exploration and geophysical program over the next 3 months, in preparation for a planned drilling

campaign at Zeus during October / November 2018.” This program will comprise gridded and systematic soil

sampling, CoreScan1 alteration mapping, along with detailed geological mapping, ground magnetic and electrical

geophysical surveys.

The Zeus Project

Zeus is a large area HSE prospect owned and controlled by Mirasol. It is located in an underexplored region of

the prolifically mineralized Mio-Pliocene age mineral belt of Northern Chile (see news release January 16, 2018),

which Mirasol believes to be prospective for the discovery of new world-class size Au+Ag deposits, as exemplified

by the recent discoveries by Gold Fields of the 3.8 Moz Au Salares Norte 3, and the Barrick Gold 6.8 Moz Au

Alturas4 HSE gold deposits.

Mirasol’s Zeus projects hosts two presently recognized breccia gold targets: Artemisa and Apollo.

Artemisa: Mirasol’s exploration has outlined a n 800m diameter breccia which hosts advanced argillic

alteration where preliminary reconnaissance-level soil sampling has defined a low -level coincident

Au+Ag+As+Cu+Pb+Sb+Mo geochemical anomaly, which overlies the edge of the area of mappable breccia

body.

Apollo: Comprises a 0.6 x 1.2 km wide crescent -shaped zone of advanced argillic a nd intermediate argillic

alteration overprinted on pyroclastic breccias and volcanoclastic sediments which outcrop in an erosional

window through post-mineral (late) lava flows. This alteration is interpreted by Mirasol’s geologists to be

hosted by a poorly exposed phreatomagmatic breccia and flow -dome complex. Mirasol has undertaken

initial mapping, the collection of 218 rock chip sampl es, and alteration modelling throughout the Apollo

alteration window. Assay results show wide -spread strongly anomalous Ag+As+Ba+Hg+Sb, with 38 of 218

samples returning gold assays in the range 0.1 to 1.28 g/t Au.
