en.Wedoany.com Reported - Mirasol Resources has provided an update on exploration progress at its 100%-controlled Sobek copper, gold, and silver project in the Vicuña district of northeastern Chile. The company has completed the exploration season at the Sobek project, located 7 kilometers west of Filo del Sol and 3 kilometers southwest of Lunahuasi. New data has enhanced interest in the VN-Zone, 46 South, and Green Wall targets within the Sobek Central corridor, elevating the VN-Zone as a priority target for future drilling campaigns.
Sobek is situated in a high geological interest environment due to its proximity to related discoveries in the Vicuña district. The project was staked in 2016, predating the discovery of the Filo del Sol high-grade feeder zone in 2021 and the Lunahuasi discovery in 2023. This early position allowed for the consolidation of claims within a north-south trending regional structural corridor, which is cut by northwest-trending trans-Andean lineaments.
One of the main outcomes of the update is the repositioning of the VN-Zone as a high-priority target. Mirasol describes the area as a gold-copper target characterized by banded quartz veins and historical high-grade surface samples. Previously reported selective rock chip results returned 5.03 g/t gold with 2,200 ppm copper, as well as 4.50 g/t gold and 2.82 g/t gold with 1,300 ppm copper. The company clarified that these are selective surface samples and therefore not necessarily representative of average grades or economic continuity. The novelty lies in the reinterpretation of these results within a new geological and geophysical framework. A Pole-Dipole induced polarization survey conducted over the VN-Zone outlined a structurally controlled strong resistivity contrast that increases with depth. Geologically, mineralization at the VN-Zone may be associated with a structural corridor developed in dacitic volcanic rocks and possible subvolcanic intrusions, with the company identifying multiple vein textures including black banded quartz veins, D-type quartz-pyrite veins, and magnetite-quartz veins.
The season also included drilling at 46 South, located at the southern end of the Sobek Central corridor. Mirasol completed two diamond drill holes at this target, with the second hole, S46-DDH-002, collared approximately 300 meters south of the first. Results from the second hole confirmed the continuity of the hydrothermal system south of the 46 South target, encountering oxidized and altered dacitic rocks, local hydrothermal breccias, cataclastic textures, silicification, clay alteration, oxide zones rich in iron oxides and jarosite, as well as tectonic breccia and fault gouge intervals. Reported anomalous intervals include: 4.50 meters at 0.07 g/t gold, 223 ppm copper, and 22 ppm molybdenum from 21.50 meters; 3.00 meters at 0.14 g/t gold and 188 ppm copper from 38 meters; within this interval, the best single gold value was 0.32 g/t between 39 and 40 meters; and 3.72 meters at 0.16 g/t gold from 116.80 meters, including 2 meters at 0.23 g/t gold.
Another relevant point in the update is the Green Wall, located north of the Sobek Central corridor. The company defines it as a more copper-rich mineralized trend. Previously reported selective samples returned copper grades up to 14.7% with 131 g/t silver and 74.1 ppm molybdenum in narrow structures less than one meter wide. In the new interpretation, these results are placed within a northwest-trending mineralized corridor. At Green Wall Northwest, the main geochemical association is copper-silver-molybdenum, with copper oxides and preserved sulfides such as chalcocite, remnant bornite, digenite, and covellite. At Green Wall Southeast, Mirasol identified a different gold-tellurium-bismuth-copper association, reporting values of 0.93 g/t gold, 93.8 ppm tellurium, 3.39% copper, and 58 g/t silver.
Key data includes: the company is Mirasol Resources, the project is Sobek, Mirasol holds 100% ownership, target commodities are copper, gold, and silver, location is the Vicuña district of northeastern Chile, geological proximity is 7 km west of Filo del Sol and 3 km southwest of Lunahuasi, main zones are VN-Zone, 46 South, and Green Wall, status is exploration and drill target refinement, laboratory is ALS Global in Santiago and Copiapó, Chile, the company reports analytical protocols, and the qualified person is Tim Heenan, President and CEO of Mirasol, compliant with NI 43-101 standards.
The Sobek update comes as the Vicuña district consolidates as one of the most closely watched areas in South American copper mining. The formation of Vicuña Corp., a 50/50 joint venture between BHP and Lundin Mining, integrating Filo del Sol and Josemaría, has enhanced the district's global profile. For Chile, Sobek represents an early-stage exploration project with high uncertainty, no declared mineral resources, or published economic estimates. Its relevance lies in pointing to a possible new mineralized system within the Andean metallogenic belt. The main challenge for Mirasol will be to translate geological and geochemical signals into consistent drill intercepts.
The next milestone will be to define new drilling, particularly at the VN-Zone and Green Wall. For now, Sobek remains an exploration project without resource estimates or mining plans, but the combination of its location, new targets, and proximity to related discoveries in the Vicuña district keeps it on the radar for copper exploration in Chile.
