PR Newswire
TORONTO , April 21, 2022 /PRNewswire/ - Magna Gold Corp. (TSXV: MGR) (OTCQB: MGLQF) ("Magna" or the "Company"), is pleased to report the maiden mineral resource estimate (the "Resource") for the Margarita silver deposit at its 100% owned Margarita Project (the "Margarita Project") in Chihuahua, Mexico .
- Indicated mineral resources are estimated to be 1.854 million tonnes ("Mt") at 204.9 g/t Ag and Inferred mineral resources of 0. 454 Mt at 153.4 g/t Ag above a 75 g/t Ag cut-off grade.
- Includes Indicated resources of 12.22 million ounces ("Moz") of Ag and inferred resources of 2.24 Moz Ag .
- Margarita Vein High Grade Core – The deposit contains a well-defined high-grade core that demonstrates excellent continuity. Resources contained within this core are estimated to be 0.78 Mt @ 332.1 g/t (Indicated) for a metal content of 8.32 Moz of silver.
- Strong Resource Growth Potential – Our first pass drill program focussed on defining the mineralization contained within the Margarita vein. This structure remains open in all directions and at depth. Our drill program also discovered and confirmed the presence of multiple parallel vein systems most notable of which were the Juliana and Caido veins. These veins are strongly mineralized, and follow-up drilling will focus on defining additional resources in these parallel veins to be included in subsequent resource updates. The current resource estimate only incudes mineralization in the main Margarita vein.
- Development Advantages – The Margarita Project is in a mining friendly jurisdiction with great access, infrastructure and availability of skilled workers.
President and CEO Arturo Bonillas commented; "Delivery of a maiden resource estimate is a huge milestone for the Company. The team delivered this robust resource on schedule and on budget. We have unlocked tremendous value through the drill bit and there is great potential for significant resource growth in the near term. Our exploration program defined a high-grade resource and discovered several parallel structures. We look to add the newly discovered structures in our next resource update and anticipate material increases in the mineral inventory." Mr. Bonillas continues, "We are on track to release a PEA in the coming months and will be making a construction decision before the end of 2022. Based on what we have seen so far I am confident the Margarita Project will generate significant value for our shareholders for years to come."

Mineral Resource Notes:
- The effective date for the Margarita Project mineral resource estimate is April 08, 2022 .
- The report includes only mineralization that is completely inside Magna's 100% owned mining concessions boundaries.
- The mineral resources are reported based on an underground mining method scenario, assuming a recoverable crown pillar of 15 m , and constrained reasonable underground prospects for economic extraction.
- The mineralized envelopes were modelled at a base case cut-off grade of 25.0 g/t Ag for Vein 2 and Vein 2 South and 300.0 g/t Ag for the High-Grade vein. The High-Grade vein is entirely contained within the south side of the Vein 2 envelope. All modelling work was conducted using Leapfrog Geo Software.
- For the purposes of the mineral resource estimate the High-Grade vein resources, while contained within the Vein 2 envelope, are estimated exclusive of the Vein 2 resources.
- Grade capping was applied to reduce the influence of outlier samples; 350.0 g/t Ag was used for the Low-Grade envelopes (Vein 2 & Vein 2 South) and 1,000.0 g/t Au was used for the High-Grade vein.
- The economic parameters used to define mineral resources is a metal price of US$25.0 per troy ounce silver, an underground mining cost US$20.28 /t, a processing cost of US$17.57 /t and a G&A cost of US$4.57 /t for a total of US$42.42 /t mined and processed. The silver recovery was estimated at 78%.
- The economic Ag cut-off grade calculated from the economic assumptions is 68.0 g/t Ag, however, Magna decided to report resources at 75.0 g/t Ag given the nature of high-grade continuity of the deposit.
- The mineral resource has been categorized in the Indicated category for that portion where 3 or more drillholes are located within 80 m distance along strike and down dip, all remaining blocks remain in the Inferred category.
- The mineral resources presented here were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council May 10, 2014 .
- Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, socio-political, marketing, or other relevant issues.
- The mineral resource estimate has been prepared without reference to surface rights or the potential presence of overlying public infrastructure.
- Figures may not total due to rounding.

*Notes for the Sensitivity Table:
- The cut-off grades used in the sensitivity analysis have been reviewed and have been found to meet the test of reasonable prospects of economic extraction.
- The sensitivity analysis has been conducted on the global resources prior to classification to illustrate the current potential for each zone at each cut-off grade. This is because the continuity of both the vein and mineralization have been demonstrated.
Drill core and rock samples were shipped to ALS Global in Chihuahua, Chihuahua, Mexico and in North Vancouver, Canada for sample preparation and for analysis at the ALS laboratory in North Vancouver. The ALS Chihuahua and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. Silver and base metals were analyzed using a four-acid digestion with an ICP finish and gold was assayed by 50-gram fire assay with atomic absorption ("AA") finish. Over limit analyses for silver were assayed by fire assay and gravimetric finish. Over limit analysis for lead and zinc were re-assayed using an ore-grade four-acid digestion with AA finish.
Control samples comprising certified reference samples, duplicates and blank samples were systematically inserted into the sample stream and analyzed as part of the Company's quality assurance / quality control protocol.
Magna is a Mexico focused gold/silver production company engaged in acquiring, exploring, developing and operating quality precious metals properties in Mexico . It is committed to advancing its 100% owned flagship San Francisco Mine, the Margarita Project and other highly prospective mineral properties located in Sonora and in Chihuahua. The primary strength of the Company is the team of highly experienced mining professionals with a proven track record of developing properties in Mexico from discovery to production.
