Mirasol Announces Start of Maiden Drill Program at Libanesa Silver-Gold Project, Argentina

VANCOUVER, British Columbia, March 24, 2022 (GLOBE NEWSWIRE) — Mirasol Resources Ltd. (TSX-V: MRZ) (OTCPK: MRZLF) (the “Company” or “Mirasol”) is pleased to announce that its partner Golden Arrow Resources Corporation (“Golden Arrow”) has initiated a maiden diamond drilling program at the Libanesa silver-gold project (“Libanesa”) in Santa Cruz province, Argentina. Up to 2,000m of drilling will be completed in eighteen holes ranging from 75 to 250m in depth to test the Cerro Redondo, Lagunita and Lagunita West prospects.

Mirasol’s President Tim Heenan commented: “We are pleased by the fast progress from our partner at Libanesa. Their surface work has confirmed and refined the drill targets previously delineated by Mirasol as well as identifying new prospective targets.”

Libanesa is a 14,500-hectare silver-gold (lead) project located at the northeastern margin of the Deseado Massif Gold-Silver metallogenic province, approximately 40 km northwest of the Cerro Moro Mine operated by Yamana Gold and 100 km northeast of the Don Nicolas mine operated by Cerrado Gold. Golden Arrow may earn a 75 percent interest in Libanesa over six years by spending US$4 million on exploration; completing a minimum 2,000m drill program; and making payments to Mirasol totalling US$1 million. Mirasol would retain a 25 percent participating interest in the project (news release October 12, 2021).

Following the execution of the definitive agreement, Golden Arrow, as operator, conducted a detailed surface work program to refine the previously defined targets and evaluate additional areas within the property. To date, they have collected 274 channel and rock chip samples by opening 20 trenches.

Target Highlights:

This summary is based on the information provided by Golden Arrow and discussed in their News Release dated March 24, 2022. It was reviewed by Mirasol’s Qualified Person.

The Cerro Redondo prospect area includes a sub-circular geomorphic feature, approximately 1 km in diameter, that hosts multiple gold-silver-lead anomalies inside and at its margins. There are several additional targets within approx. 500m of this feature. Cerro Plomo is the principal target in this prospect and is characterized by a well-mineralized gold-silver hydrothermal breccia that is exposed at surface. This target is also supported by both chargeability and resistivity geophysical anomalies at depth. The hydrothermal breccia is approximately 50m in diameter and is hosted in lapilli and crystal tuffs and pyroclastic breccias. Mineralization is mainly hosted in the matrix of the breccia with rock chip samples grading up to 2.55 g/t Au and 2,802 g/t Ag. Channel samples also returned up to 11m at 1.21 g/t Au and 13.5 g/t Ag (see news release June 1, 2021 for details on previous work completed by Mirasol). Recent detailed channel sampling completed by Golden Arrow confirmed disseminated mineralization in the crystal tuffs outside the main hydrothermal breccia with up to 0.32 g/t Au and 15 g/t Ag. Thirteen drill holes are planned at Cerro Redondo.

Approximately 5.5 km north of Cerro Redondo, the Lagunita target includes typical low sulfidation type epithermal veins and breccias. Intermittent vein occurrences, outcropping/sub-cropping through post mineral cover, were mapped by Mirasol over a strike length of approx. 2.3 km. Golden Arrow’s surface work program has identified a second target, Lagunita West, where silicified tuffs with quartz veinlets and disseminated pyrite define a different epithermal system that includes high gold and low silver. Twelve rock chip samples collected by Golden Arrow over 400m at Lagunita West returned four anomalous values of 2.4 g/t Au, 0.31 g/t Au, 0.17 g/t Au and 0.15 g/t Au, coincident with a northwest striking magnetic low. Five drill holes are planned for these two targets.
