- Altitude of 3,200 to 3,900 meters ASL
- Adjacent to 2 advanced projects (operated by Codelco and Mineria Activa)
In July 2025, Mirasol signed an Option to Purchase Agreements under which Mirasol grants Pampa Camarones SpA, through its affiliate Eco Earth Elements SpA, (“Eco Earth”) an exclusive right to acquire the mineral rights within Mirasol`s 100% owned Nord East and Nord West Projects (“Nord Project”) located in Region II of Chile (news release July 15, 2025). The Nord project is directly adjacent to Pampa Camarones´ Ciclón-Exploradora development project, which is advancing to production, and will serve as key properties for the development of essential infrastructure, while also increasing potential resources and adding exploration upside.
Under the terms of the Agreement, Mirasol shall grant Eco Earth the rights to acquire the Nord East and Nord West for total consideration of US$2.5 million by making scheduled payments over 4 years. Upon completion of payments, Eco Earth will have earned 100% interest in the Nord project and Mirasol will retain a 2% NSR (Net Smelter Return) royalty on Nord East and a 1% NSR royalty on Nord West. Eco Earth will have the right to purchase the first 1% of the 2% NSR royalty on Nord East for US$3 million and the remaining 1% for an additional US$6.0 million.
The Nord project is comprised of 1,900-ha project is located in Region III of Chile within the Exploradora District, which lies on the western side of the north-south trending regional scale Domeyko fault zone and within the world class Eocene-Oligocene porphyry Cu belt.
Exploration Results
Based on Mirasol’s initial surface exploration, the project has the potential to host two main styles of mineralization. The first style is characterized by large vein-type mineralization injected into fault structures hosting polymetallic (Cu, Zn, Pb, Ag, Au) mineralization, as seen in the active small-scale mines located near the northeast corner of the claim boundary and at Mineria’s Ciclon-Exploradora polymetallic development project, which is located adjacent to the eastern blocks of the project. While surface geochemistry has returned only low to anomalous precious and base metal results, Mineria’s understanding will be valuable to define drill targets for potential extensions or parallel structures to the known mineralization (news release October 31, 2019).In addition, the project also hosts the potential for porphyry Cu-Au style mineralization. In the central part of the property a large alteration zone displays patterns of quartz-sericite and advanced argillic alteration with thin tourmaline veinlets, which are characteristic of some porphyry-style alteration assemblages.
In the first half of 2021, Encantada completed an initial fieldwork program, which included geological mapping, geochemistry and geophysical surveys to define targets. A scout diamond drill program was completed largely on a property controlled by Encantada (Target 1) and adjacent to Nord, with one initial drill hole completed within the Nord tenure to test a Au-Cu mineralized corridor.
Follow up drilling took place at Nord in October and November 2021 to test the multiple north-northeast trending mineralized corridors identified on the property. Encantada completed five drill holes totaling 1,192m on Target 3 in the center of the Nord project. Narrow zones of Zn mineralization (sphalerite - pyrrhotite) were encountered in the northern holes with higher temperature (garnet-pyroxene-magnetite) skarn carrying narrow zones of Cu-Au mineralization intercepted in the south. The skarn and increasing Cu-Au+Mo values may indicate a vector towards a porphyry target to the southeast.
At Target 2, geological mapping at 1:2,000 and 1:5,000 scale has been completed on a porphyry prospect interpreted to be of similar Mid Eocene-Oligocene (33-36 Ma) age to the Exploradora complex, which is located 4 km to the northeast. Three porphyry intrusives with potassic (secondary biotite) alteration, overprinted by strong sericite-clay alteration with local alunite, limonite and Cu oxides, occur in two elongated 200 x 500m and 150 x 300m zones. Porphyry-type veining includes early biotite-magnetite (“EB”) veins and scarce A veins along a north-northwest trend near the contacts of the porphyry with the monzodiorite intrusive host rock. An IP geophysical survey completed over the area has defined a strong and broad chargeability anomaly from 100-500m depth associated with the altered porphyry intrusions.

Encantada is evaluating further geochemical and geophysical surveys to develop and refine potential new drill targets.
