Mirasol Consolidates Additional Claims with its Los Amarillos Gold - Silver Project in Chile and Announces Initial Exploration Results

VANCOUVER, June 26, 2019 - Mirasol Resources Ltd. (TSX-V: MRZ) (OTCPK: MRZLF) (the "Company" or "Mirasol") is pleased to announce that it has executed an Option to Purchase agreement (the "Agreement") with Empresa Nacional de Minería ("ENAMI") of Chile to consolidate and gain control of claims hosting potential extensions to the mapped mineralization on the surface of its Los Amarillos project. The project is located to the northwest of the El Salvador mine and of the Potrerillos smelter on the prospective Paleocene age mineral belt of northern Chile (figure 1).

Mirasol's President and CEO, Norm Pitcher, stated: "We are pleased to announce this Agreement and introduce a new project in our portfolio. This Agreement is in line with our strategy of consolidation around our property packages to develop large scale targets. The Los Amarillos project to date has returned high grade gold and silver assays in rock chip samples and it warrants a detailed surface exploration program to define drill targets. Given the project location near existing infrastructure, its year-round access and initial results, it represents a compelling project for Mirasol to initially move forward on a self-funded basis."

Terms of the Agreement:

Mirasol holds the right to acquire 100% of 288 ha of claims (the "ENAMI Claims") by completing US$300,000 in exploration expenditures over 3 years (including a committed US$50,000 for the first 12 months) and by making total cash payments of US$100,000 over the same period. The first US$10,000 payment has been made on signing. Once the option period is completed, ENAMI will hold a 1.5% NSR royalty on the ENAMI Claims, which will be subject to a right of first refusal held by Mirasol.

Los Amarillos project Overview:

The consolidated Los Amarillos Project occupies 1,660 ha and is 15 km north of Mirasol's Rubi project and 10 km northwest of Coldelco's El Salvador mine. The property sits at elevations ranging from 1700m to 2100m ASL. Year-round road access is excellent, and both power and water lines traverse the northern edge of the claim block.

The project is part of the Paleocene-Lower Eocene Caldera and is located within the Ojos Del Salado trans-orogen structure that also hosts the El Salvador (Cu-Mo-Au), Potrerillos (Cu-Au), and La Coipa (Ag-Au) deposits. Mineralization at Los Amarillos is hosted within a thick sequence of rhyodacitic to trachytic pyroclastics and flows within the caldera, with quartz-adularia-carbonate Intermediate Sulfidation veins hosted along north-south structures, coincident with rhyolitic to dacitic dyke swarms.

Numerous vein structures up to 3 m wide have been mapped over a 7 km strike length throughout the project (figure 2). Vein filling is massive to banded quartz with polymetallic (Au-Ag-Cu-Pb-Zn) mineralization and barren later stage carbonates. Reconnaissance rock chip sampling of quartz veins has returned assays up to 40.5 g/t Au with anomalous antimony, arsenic, and barium. Zones of narrow veinlets and stockwork within the wall rock carry up to 2.7 g/t Au. In addition, there is evidence of wider zones of sheeted veins and breccias zones that may be a target for bulk mining. Numerous old and small-scale artisanal pits exist within the claim block but there has been no modern exploration or drilling beyond the initial reconnaissance work completed by Mirasol (figure 3).

Mirasol is currently defining a follow up exploration program and budget that will be part of the overall 2020 financial year exploration plan for the Company. Additional surface exploration work is expected to start shortly.
