Mirasol Signs Letter Of Intent to Option its Virginia Silver Project in

Argentina

VANCOUVER, BC, February 27, 2020 — Mirasol Resources Ltd. (TSX-V: MRZ) (OTCPK: MRZLF) (the “Company”

or “Mirasol”) is pleased to announce the signing of a Letter of Intent (“LOI”) with Golden Opportunity Resources

Corp. (“Golden Opportunity”) (CSE:GOOP) for its Virginia Silver project (the “Project”) in the Santa Cruz Province

of Argentina. With its known resource and clear exploration targets, the Project is a compelling asset for Golden

Opportunity to further explore and advance.

Norm Pitcher, President and CEO of Mirasol stated: “We are pleased to partner with Golden Opportunity to see

the exploration upside at Virginia drill tested. With t his transaction , Mirasol will retain exposure to new

discoveries through our right to earn a significant share position in Golden Opportunity and as a royalty holder.”

Terms of the Transaction

Mirasol shall grant Golden Opportunity the option to acquire 100% of the Project over 3 years by:

- Making share issuances totalling 19.9% of the share s outstanding (the “S/O”) of Golden Opportunity at

the time of vesting:

o On signing of the definitive agreement: 9.9% of the S/O

o On first anniversary: 5% of the S/O

o On Second anniversary: 5% of the S/O

o On third anniversary: top up to 19.9% of the S/O (inclusive of the previous issuances)

- Completing US$6M in exploration expenditures

o Year 1: US$1M (firm commitment)

o Year 2: US$2M

o Year 3: US$3M

- Mirasol will be the operator of the project during the option period and receive a management fee.

Upon completion of the option, Golden Opportunity will have earned a 100% interest in the Project and Mirasol

will retain a 3% NSR royalty, of which 1% can be bought back by Golden Opportunity for US$2M.

The LOI is subject to customary conditions including exchange approval, definitive agreement drafting as well as

to Golden Opportunity completing an equity financing of not less than US$ 1 million within 90 days. Mirasol has

granted Golden Opportunity an exclusivity period to complete this transaction.

Virginia Silver Project Overview

Mirasol first discovered the Virginia silver deposit in 2009, following-up a high -priority reconnaissance target

identified by its generative team. Over the next few years, Mirasol defined high-grade, intermediate sulfidation

epithermal style mineralization in a series of prominent outcrops of vein -breccia that are associated with a

rhyolitic volcanic flow dome field. Rock chip and saw cut channel sampling over these outcrops defined significant

strike lengths of continuously mineralized vein -breccia, with many samples assaying over 1 ,000 g/t Ag . From

2010 to 2012, Mirasol completed a series of drill programs at the Project, drilling a total of 23,318 m of diamond

core in 223 holes, testing the mineralized structures to a maximum depth of 266m. This work was followed by

the filing of an amended NI 43-101 Resource Estimate report in 2016 defining seven outcropping bodies of high

grade silver mineralization , constrained1 within conceptual pit s, with an indicated mineral resource of 11.9

million ounces of silver at 310 g/t Ag and a further inferred 3.1 million ounces of silver at 207 g/t Ag (figure 1

and amended NI 43 -101 technical report filed February 29, 2016).

Later that year , Mirasol reported that preliminary prospecting of new claims identified quartz vein and vein -

breccia rock float, scattered along a 2 km trend. With a strong belief in the exploration potential of the Virgin ia

district, Mirasol further expanded its property holdings in 2017 with an extra 27,017 ha of claims to the south of

the limit of previous drilling. In May 2018, high grade silver assay results were reported from the additional

prospecting of three new target areas, suggesting the potential for an unrecognized, shallow soil covered, high

grade mineralization that would expand the potential of the Virginia silver project (figure 2, 3 and 4).

Mirasol looks forward to testing the exploration upside at Virginia with Golden Opportunity at a time of

improving precious metal prices.

1 The Qualified Persons responsible for this amended Technical Report were commissioned by Mirasol Resources Ltd. to review all

geologic, geochemical, geophysical, surface trenching, diamond drill core sampling and metallurgical recovery data pertaining to the

Virginia Project for the purpose of completing a Mineral Resource estimate in accordance with the guidelines of the Canadian Institute of

Mining and Metallurgy (CIMM). For calculating conceptual pits , a silver price of US $20 per ounce was used. Sensitiv ity analyses by the

Qualified Persons indicate that the Mineral Resources are not particularly sensitive to operating costs or silver price fluctuations. Mineral

Resources which are not Mineral Reserves do not have demonstrated economic viability.
