VANCOUVER, British Columbia, Nov. 24, 2021 (GLOBE NEWSWIRE) -- Mirasol Resources Ltd. (TSX-V: MRZ) (OTCPK: MRZLF) (the “Company” or “Mirasol”) today provided an update on exploration plans for the current field season and is also pleased to report that drilling has commenced at its Newcrest-partnered Gorbea Au project in Northern Chile.

Tim Heenan, Mirasol’s President stated: “We have made excellent progress on our self-funded and partnered projects and are off to a very strong start this field season. Drilling is currently underway at our partnered projects Gorbea, Nord and Virginia. We are very excited to be preparing for a maiden ground exploration program at our self-funded Sobek project to follow up on compelling magnetic features identified in the recently completed aeromagnetic survey. We are also currently conducting a deep-penetrating geophysical survey at our self-funded Sascha Marcelina project, which will be followed up by deep drilling to further test the principal sulphide-rich Pellegrini breccia target.”

A webinar with Tim Heenan, the Company’s President and Patrick Evans, the Executive Chair will be held on December 7th, 2021 at 10:00 am PT / 1:00 pm ET. A short presentation will be followed by a Q&A session. Registration can be completed using this link.

Chile Update:

  • Gorbea Au/Ag Project – Under Option to Newcrest Mining Limited

Newcrest plans to complete five reverse circulation drill holes for 2,500m on the Atlas and El Dorado prospects. Atlas is the most advanced prospect in the Gorbea high sulfidation epithermal (“HSE”) Au-Ag property package and has been the focus of Newcrest’s drilling activities to date. The El Dorado prospect is a new target that will be drill tested for the first time.

Atlas hosts widespread Au-Ag mineralization within the central breccia complex, which remains open to the north, east and southwest. Newcrest is planning to drill two holes at Atlas for 1,000m to test potential extensions and higher-grade mineralized zones.

El Dorado is located 10 km to the southeast of Atlas and the area between these two prospects is covered by post mineralization mafic volcanics. El Dorado comprises mid-Miocene felsic-andesitic lavas and volcanic breccias that have been intruded by daci-andesite domes and polymictic breccias with clasts of vuggy silica, which are host to a large (3.1 x 1.4 km) northwest trending zone of advanced argillic alteration. A geochemical soil sampling program completed by Newcrest has defined an anomalous zone of pathfinder elements including Sb, As, Se and Bi that is associated with the margins of a dome complex in the southern part of the property. A strong association of Bi, Mo, As, Se, Hg is also seen to be closely associated with zones of steam heated alteration in both the northern and southern parts of the prospect. Newcrest also completed five survey lines of Controlled Source Audio-Magnetotellurics (“CSAMT”), totalling 11.4 km, identifying multiple highly resistive (>10,000 ohm), subvertical zones along the margins of the southern outcropping dacitic dome complex that are coincident with steam-heated and alunite-altered polymictic breccias. Based on this surface work, Newcrest will drill three scout holes for 1,500m to test the north and south zones, which are characterized by coincident geochemical and geophysical anomalies in prospective geology.
