The Sobek Cu project (“Sobek”) was staked by Mirasol in 2016 based on prospective local structural architecture hosted within a highly prospective and productive geological terrain. An important north-northeast trending mineralized structural corridor encapsulates a large part of the Sobek package, that is crosscut by a series of north-northwest trending deep seated trans-cordilleran lineaments evident through the entire property. In addition, the tenure is host to prospective Miocene/Pliocene aged geological units and intriguing satellite image ASTER alteration responses. 

The Sobek land position was expanded in 2021 and 2022 following significant results reported by Filo Mining Corp. from its Filo del Sol project located 5 km to the east of Sobek, which included a remarkable intercept of 858m at 1.80% CuEq (including 163m at 5.43% CuEq)[1]. The high-profile Vicuña Copper-Gold-Silver District is developing in the Sobek area with multiple deposits located in close proximity, including the Josemaria and Los Helados porphyry Cu-Au deposits located 10 km east-northeast and 20 km north of Sobek, respectively. The recent NGEx discovery at Lunahuasi (formerly Potro Cliffs) is just three km directly east of the southeast corner of Sobek North Block. Mirasol controls 22,840 ha of exploration claims in this district in four strategic blocks, the North, Central and South blocks and the Rosita Property, that are all on the Chilean side of the border with Argentina.

Strategic Expansion of the Sobek Property with the Addition of the SQM Rosita Property
Mirasol signed a landmark option agreement with Sociedad Química y Minera de Chile SA (“SQM”) doubling the size of the flagship Sobek Project in the Vicuña Copper-Gold-Silver District of northeast Chile (news release February 14, 2024). The SQM Property (“Rosita”) covers 11,500 ha extending the Sobek Project to the west and to the east, and importantly unifying the Sobek Central block with the Sobek North block. The combined property has doubled Mirasol’s land holding in the district for a total of 22,840 ha. The eastern portion of the Rosita property positions Mirasol within 3 km of the giant Filo Del Sol Project and the Sobek North block is 3 km from Lunahuasi discovery both within the heart of the Vicuña Copper-Gold district. SQM has granted Mirasol the exclusive option to earn 80% of the Rosita Project, subject to a 2.0% NSR royalty, by Incurring US$4 million in exploration expenditures and making annual option fee payments for a total of US$3 million scheduled over 6 years.
