[{"type":"text","content":" VANCOUVER, British Columbia, June 09, 2022 (GLOBE NEWSWIRE) -- Mirasol Resources Ltd. (TSX-V: MRZ) (OTCPK: MRZLF) (the “Company” or “Mirasol”) is pleased to report the exploration results from its 100% controlled Tefnut copper prospect (“Tefnut”), located within the fertile Mio-Pliocene copper-belt in the province of San Juan, Argentina. The province of San Juan hosts several high-profile advanced projects including Filo del Sol, Josemaria, Altar, Los Azules and El Pachon. Tefnut, staked by Mirasol through its project generation program, comprises approximately 4,500 hectares of exploration claims. The Company’s preliminary reconnaissance program of prospecting, high level geological mapping, geochemical sampling and alteration analysis, successfully defined a large 1.5 by 1.5 kilometres porphyry related phyllic alteration system with outcropping copper-mineralization. “We are very excited to introduce a new high-quality porphyry copper target within the renowned province of San Juan,” Mirasol’s President, Tim Heenan, commented. “Our first boots on the ground reconnaissance over this completely untested area has identified a sizeable new alteration at Tefnut that we will continue to advance to drill testing.” Tefnut is located at the intersection of a major orogenic parallel NS structure and a lesser defined NNW trans-orogenic lineament which is the common structural configuration that has localized other major deposits and development projects in the province of San Juan. In close proximity to the west and in Chile, advanced projects like Novicio, West Wall and Pimenton represent good analogies for the prospectivity of the immediate area. Figure 1: Location Map - Mirasol Tefnut Prospect Within the large 1.5 x 1.5 kilometre intensely altered phyllic footprint at Tefnut, discrete outcropping exposures of porphyry-style copper-mineralization occur in the deeply incised creeks. This mineralization is associated with high density stockworks of quartz magnetite and fine magnetite only stringers, within strongly potassic altered (biotite-feldspar-magnetite) intrusive dioritic porphyry hosting disseminated chalcopyrite and Cu-oxides. Initial grab samples from these mineralized outcrops have returned 0.14% and 0.19% copper. In addition, anomalous molybdenum values of 42 ppm hosted in type B veinlets, with the four highest values (from ...
