New style of mineralization intersected in the hanging wall above the Sooy Vein in Drill Hole 21-231
HALIFAX, NS / ACCESSWIRE / July 13, 2021 / Silver Tiger Metals Inc. (TSXV:SLVR)(OTCQX:SLVTF) (“Silver Tiger” or the “Corporation”) has intersected 2,063.3 g/t silver equivalent over 0.5 meters in the Sooy Vein hanging wall in Drill Hole ET-21-231 from 270.0 meters to 270.5 meters within a broader mineralized interval of 10.8 meters grading 368.6 g/t silver equivalent from 262.3 meters to 273.1 meters. This hole intersected the Sooy Vein on Section 4425N, approximately 475 meters to the south along strike from discovery hole ET-20-202 (see Silver Tiger press release dated Feb. 2, 2021). This mineralized zone, referred to as the crackle breccia zone, is located in the hanging wall above the Sooy Vein and is represented by pervasive silicification in the brecciated tuffs of the Flat Formation with both disseminated pyrite and stringers/veinlets of quartz-pyrite-galena-sphalerite and chalcopyrite.
Drill hole ET-21-231 also intersected the Sooy Vein deeper down hole returning 1.5 meters grading 749.4 g/t silver equivalent within a broader mineralized interval of 21.9 meters grading 179.7 g/t silver equivalent from 289.3 meters to 311.2 meters.

El Tigre Resource Estimate
After acquiring El Tigre, Silver Tiger drilled 12,500 meters to define the wide halo of near surface gold mineralization around the mined high-grade veins of the historic El Tigre Mine. This allowed Silver Tiger to deliver a maiden resource estimate for the El Tigre Property to a depth of 150 meters containing indicated resources of 661,000 gold equivalent ounces at 0.77 g/t (21 g/t silver and 0.51 g/t gold) and inferred resources of 341,000 gold equivalent ounces at 1.59 g/t (88 g/t silver and 0.52 g/t gold). The National Instrument 43-101 Technical Report titled “NI 43-101 Technical Report and Updated Mineral Resource Estimate on the El Tigre Project, Sonora, México” effective as of September 7, 2017 and dated October 26, 2017 prepared by David Burga, P.Geo., Yungang Wu, P.Geo., Fred Brown, P.Geo., Jarita Barry, P.Geo., Eugene Puritch, P.Eng., FEC, CET, Alfred Hayden, P.Eng. and Richard H.

About the El Tigre Historic Mine District
Silver Tiger Metals Inc. is a Canadian company whose management has more than 25 years’ experience discovering, financing and building large hydrothermal silver projects in Mexico. Silver Tiger’s 100% owned 28,414 hectare Historic El Tigre Mining District is located in Sonora, Mexico. Principled environmental, social and governance practices are core priorities at Silver Tiger.
The El Tigre historic mine district is located in Sonora, Mexico and lies at the northern end of the Sierra Madre silver and gold belt which hosts many epithermal silver and gold deposits, including Dolores, Santa Elena and Las Chispas at the northern end. In 1896, gold was first discovered on the property in the Gold Hill area and mining started with the Brown Shaft in 1903. The focus soon changed to mining high-grade silver veins in the area with production coming from 3 parallel veins the El Tigre Vein, the Seitz Kelley Vein and the Sooy Vein. Underground mining on the middle El Tigre vein extended 1,450 meters along strike and was mined on 14 levels to a depth of approximately 450 meters. The Seitz Kelley Vein was mined along strike for 1 kilometer to a depth of approximately 200 meters. The Sooy Vein was only mined along strike for 250 meters to a depth of approximately 150 meters. Mining abruptly stopped on all 3 of these veins when the price of silver collapsed to less than 20¢ per ounce with the onset of the Great Depression. By the time the mine closed in 1930, it is reported to have produced a total of 353,000 ounces of gold and 67.4 million ounces of silver from 1.87 million tons (Craig, 2012). The average grade mined during this period was over 2 kilograms silver equivalent per ton.
The El Tigre silver and gold deposit is related to a series of high-grade epithermal veins controlled by a north-south trending structure cutting across the andesitic and rhyolitic tuffs of the Sierra Madre Volcanic Complex within a broad silver and gold mineralized prophylitic alteration zone developed in the El Tigre Formation that can be up to 150 meters wide. The veins dip steeply to the west and are typically 0.5 meter wide but locally can be up to 5 meters in width. The veins, structures and mineralized zones outcrop on surface and have been traced for 5.3 kilometers along strike in our brownfield exploration area. Historical mining and exploration activities focused on a 1.6 kilometer portion of the southern end of the deposits, principally on the El Tigre, Seitz Kelly and Sooy veins. The under explored Caleigh, Benjamin, Protectora and the Fundadora exposed veins continue north for more than 3 kilometers. Silver Tiger has delivered its maiden 43-101 compliant resource estimate and is currently drilling to update its resource estimate and publish a PEA.

Procedure, Quality Assurance / Quality Control and Data Verification
The diamond drill core (HQ size) is geologically logged, photographed and marked for sampling. When the sample lengths are determined, the full core is sawn with a diamond blade core saw with one half of the core being bagged and tagged for assay. The remaining half portion is returned to the core trays for storage and/or for metallurgical test work.
The sealed and tagged sample bags are transported to the Bureau Veritas facility in Hermosillo, Mexico. Bureau Veritas crushes the samples (Code PRP70-250) and prepares 200-300 gram pulp samples with ninety percent passing Tyler 200 mesh (Code PUL85). The pulps are assayed for gold using a 30-gram charge by fire assay (Code FA630) and over limits greater than 10 grams per tonne are re-assayed using a gravimetric finish (Code FA530). Silver and multi-element analysis is completed using total digestion (Code MA200 Total Digestion ICP). Over limits greater than 100 grams per tonne silver are re-assayed using a gravimetric finish (Code FA530).
Quality assurance and quality control (“QA/QC”) procedures monitor the chain-of-custody of the samples and includes the systematic insertion and monitoring of appropriate reference materials (certified standards, blanks and duplicates) into the sample strings. The results of the assaying of the QA/QC material included in each batch are tracked to ensure the integrity of the assay data. All results stated in this announcement have passed Silver Tiger’s QA/QC protocols.
David R. Duncan, P. Geo., V.P. Exploration of the Corporation, is the Qualified Person for Silver Tiger as defined under National Instrument 43-101. Mr. Duncan has reviewed and approved the scientific and technical information in this press release.
