TORONTO, March 8, 2022 /PRNewswire/ - Magna Gold Corp. (TSXV: MGR) (OTCQB: MGLQF) ("Magna" or the "Company"), is pleased to report results from its fully-funded resource definition drill campaign currently underway at its 100% owned Margarita silver project located in the state of Chihuahua, Mexico. The goal of the program is to define the extent of the vein hosted high-grade system at Margarita leading to the maiden resource expected to be released toward the end of the first quarter. This resource estimate will lead to the completion of the first ever preliminary economic assessment "PEA" shortly thereafter.

Results in this release are from the first 22 of 43 drill holes completed by the Company. All drill holes intersected significant near surface silver mineralization over significant widths. Based on the drill results the system appears to be much wider than previously interpreted and has multiple mineralized veins running parallel to the main Margarita vein, the most significant of which are the Caido and Juliana veins. The main mineralized zone ranges in thickness of around 2-12 m with the higher-grade zones maintaining an average true width of approximately 4.5 m. Mineralization has been confirmed along a strike length of 1,600 m and remains open in both directions. Prior to the current campaign, drilling was limited to 150 m from surface.  The 2021 program has successfully extended mineralization further to depth where it remains open.

In addition to the resource definition drilling a series of holes were drilled to test the extent of the system down to 400 m. Assay results from the deep drilling are pending, however based on our observations the system continues to remain strongly mineralized and open.

    • including 3.55 m @ 567.36 g/t Ag from 84.15 to 87.70 m
  • All 22 drill holes intersected the main mineralized Margarita system with mineralization beginning at or near surface.
  • Presence of multiple parallel mineralized veins confirmed.
  • Multiple holes returned anomalous gold values with grades up to 0.31 g/t
  • Multiple holes returned significant Zinc (Zn) and Lead (Pb) values with grades up to 5.64% and 2.36% respectively

Numbers are rounded and intervals represent down hole lengths and not true widths.

Magna Gold President and CEO, Arturo Bonillas commented: "Our drill program at Margarita has been a huge success with every drill hole returning high-grade values over significant widths. The drilling has exceeded our expectations, it now appears the system is wider, higher grade and closer to surface than what we thought going into the campaign. We look forward to producing our maiden resource later this quarter and PEA shortly thereafter"

Technical Discussion 

The Margarita project is located within the Sierra Madre Occidental (SMO) and it is formed by two volcanic sequences. The Lower Volcanic Group (LVG) is dominantly andesitic and dacitic composition displaying textural variation including flows and tuffs with medium to coarse grained porphyritic texture, vesicles and agglomerate horizons. The sequence generally contains manganese oxides in proximity to the main mineralized structure. The post-mineral cover unit is the Upper Volcanic Group (UVG) and is comprised dominantly of rhyolitic ignimbrites.

The mineralization at Margarita is characteristic of quartz-barite epithermal vein breccias of low to intermediate sulphidation. The quartz vein breccia shows multi-stage formation and exhibits bladed, crystalline, chalcedonic, crustiform, colloform, comb, banded and brecciated textures. This vein breccia is hosted within the above mentioned LVG. Iron and Mangnaese oxides are abundant and occasionally sulphides like pyrite, sulphosalts, galena and sphalerite less than 5% are observed. Silver appears to be associated with the Acanthite, however further work is being conducted to identify the mineral associations.  Strong silica alteration is observed proximal to the footwall and hanging wall of the Margarita structure and minor kaolinite-smectite alteration with calcite can also be found.

A total of five mineralized vein breccias have been recognized, these vary in thickness from a few centimeters to more than 12 m: Margarita, El Caido, Juliana, Fabiana and Marie are the major parallel vein structures, these trend from 130° to 150° and dip from -65° SW to sub-vertical. The system has a confirmed strike length of 1,600 m and remains open in all directions and to depth.
