Mirasol Resources Ltd. reported that the 2022/23 exploration program continues to advance towards drilling at the Company's 100%-owned Sobek Copper Project in Chile. Sobek was originally staked based on prospective local structural architecture prior to the 2021 discovery of the high-grade feeder zone at the Filo del Sol gold-copper deposit located 7 km to the east. Sobek was staked in 2016 based on the local structural architecture with a compelling north-northeast trending mineralized structural corridor crosscut by a north-northwest trending deep-seated trans-cordilleran lineament.

This is a common structural configuration hosting several southern Andes metal deposits in both Chile and Argentina. Sobek comprises a large block of properties totaling 11,120 ha of exploration claims in three strategic locations, the North, Central and South blocks. The high-profile Vicuña Copper-Gold-Silver District is developing in the Sobek area with multiple deposits in close proximity, including the Filo del Sol mid-Miocene epithermal porphyry gold-copper deposit 7 km east of Sobek; the Josemaria copper-gold project 10 km to the east-northeast of Sobek; the Los Helados Porphyry copper-gold breccia system 20 km to the northeast of Sobek; and, the giant Eocene El Morro Porphyry copper-gold deposit 16 km to the west-southwest.

Airborne Mobile MT Geophysical Survey Planned for Sobek Mirasol has contracted an Airborne Mobile MT survey projected to cover the entire Sobek Central area including the CLP, Central Breccia and the VN zones with tightly spaced (100m) helicopter flown lines. Airborne Mobile MT has high-definition depth penetration to greater than 800m depth below the surface and has been proven effective in defining targets in high-sulfidation epithermal (HSE) and porphyry systems elsewhere in Chile. This MT survey will aid in refining high-priority targets for the upcoming maiden drill campaign at Sobek Central.

SOBEK CENTRAL: VN-Zone Prospecting Results Higher grade gold results (1.04 & 1.61 g/t gold) from recent select grab samples collected while prospecting in the high elevation VN-Zone at Sobek Central are very encouraging. These gold results were sourced from “Maricunga Type” quartz-magnetite veinlets with argillized margins. The M veinlets also contain anomalous values of copper (700 ppm), which is typical in gold-copper “Maricunga Type” porphyry deposits.

A more detailed mapping and sampling campaign is currently underway to better understand the significance of these encouraging high-grade results and the geological environment and controls on mineralization. SOBEK CENTRAL: Green Wall Zone Extended Further to the East-Southeast Along Trend Results from recent select grab samples collected at the Green Wall Zone has extended the mineralization 1,000m to the southeast towards the edge of the Central Breccia Zone. The structure in this zone appears to narrow and is represented by quartz stringers and centimeter scale veinlets hosting visible green copper mineralization returning results above 1.0% copper.

Anew narrow “seam”, now called the Grieta Verde Zone, further to the south of the CLP-Zone and somewhat oblique to the Green Wall Zone, has returned encouraging copper values with highly anomalous gold averaging 0.25 g/t gold from the 10 select grab samples collected from this area. This narrow “seam” injected into the hosting sediments is similar to that seen in the Green Wall Zone, which is also hosted in the sediments on the north side of the CLP-Zone. At Grieta Verde, the copper mineralization is also present in the hosting sedimentary conglomerates and appears to have been concentrated in and around the clasts within the sediments.

While neither of these zones represent potential stand-alone targets, the high-grade copper values with associated gold within the hydrothermal system is potentially sourced from a larger concealed body under either the CLP or the Central Breccia zones, which will be the focus of the maiden drill campaign. SOBEK CENTRAL: Expansion of Polymetallic Soil Anomaly The Sobek Central soil sampling grid was expanded to infill and increase the coverage 450m to the southeast of the Central Breccia Zone. The expansion and infill of the soil grid shows a clear extension of the Central Breccia polymetallic soil anomaly to the southeast and appears to highlight a copper halo around the main breccia body with a strong lead/zinc anomaly directly above it.

Another widespread copper soil anomaly appears to be emerging to the southeast of the Central Breccia Zone beyond a 250m “quiet” zone. This copper soil anomaly is emerging with some continuity, coincident with smaller areas of anomalous lead, zinc, silver and gold. Sampling crews will be continuing to advance the soil grid further to the southeast and on to the south to cover the area which host the gold-bearing veins at the VN-Zone.

The El Potro Zone at Sobek North is located approximately 5 km directly west of the NGEX Potro Cliffs project in Argentina. The newly encountered areas of interest within the El Porto Zone host a system of veins and veinlets of pyritic bearing quartz veins with Chrysocolla (copper-silicate). Exploration crews are currently mapping and prospecting the area and the first batch of samples are with ALS laboratory for analysis.

Preliminary geological observations are highly encouraging and suggest the presence of large Paleocene aged granitic bodies cut by what appears to be younger intrusives (Mio-Pliocene) of Syenitic and Monzonitic composition hosting fine sulphides forming “clots” within the matrix. Aphanitic intermediate pyritic dykes also cut the granites in a northeast direction, and host fine sulphide-rich veinlets with copper oxides cutting the dykes at a perpendicular angle. In addition, sub-angular float blocks within the creek beds contain molybdenite and traces of chalcopyrite hosted within what appear to be the younger intrusive rocks.

The source of these floats is currently being investigated. The El Potro access road is scheduled for rehabilitation once the Sobek Central access road has been completed to allow vehicle access to the higher elevations of the El Potro prospect.
