[{"type":"text","content":" VANCOUVER, British Columbia, Nov. 08, 2021 (GLOBE NEWSWIRE) -- Mirasol Resources Ltd. (TSX-V: MRZ) (OTCPK: MRZLF) (the “Company” or “Mirasol”) reports on the results from a diamond drill program completed at the Rubi porphyry Cu project (“Rubi”) in Chile, under an option agreement with Mine Discovery Fund (“MDF”). Drilling focused on the Lithocap and Zafiro targets, with results clearly indicating the presence of a large and strong prospective porphyry-style alteration system. MDF has confirmed their continued commitment to the project and a deep sensing Induced Polarization (“IP”) and magnetotellurics (“MT”) geophysical program is planned to help focus follow-up drilling on better mineralized porphyry targets. Tim Heenan, President of Mirasol, stated: “Rubi is located in a highly prospective neighborhood with Codelco´s El Salvador Cu Mine just 20 km to the north and in a very similar geological environment. We are pleased to continue working with MDF to explore the potential at Rubi. We look forward to the upcoming geophysical campaign to help us refine targets for our next drill program.” Joe Webb, Managing Director of MDF, added: “MDF is very encouraged with the results of the Phase I drilling at Rubi. Drilling intersected strong phyllic and sulphide alteration, plus intense anhydrite veining and sulphide mineralisation with increased alteration intensity to the south, possibly representing a single multi-kilometre scale alteration system indicative of a large hydrothermal system. MDF is looking forward to progressing exploration at Rubi.” A total of 1,887m of core in 10 vertical and inclined (-70°) holes was completed, with 719m in eight holes at Lithocap, and 1,168m in two holes at the Zafiro. Figure 1: Plan map with drill hole collar locations and key targets Summary of key porphyry Cu indicators identified: Drill results indicate proximity to a potential covered and well mineralized porphyry Cu system, based on: The occurrence of porphyritic daci-andesite intrusive rocks and hydrothermal brecciation exhibit strong quartz-sericite (phyllic) alteration overprinting now relict K-feldspar alteration that host trace fine pyrite-chalcopyrite-magnetite mineralization. Good ground preparation, which is critical for mineral deposition with strong to locally intense fracturing infilled with late gypsum/anhydrite and calcite veinin...
