Silver Tiger Discovers Wide Zone of High Grade Silver Mineralization in Black Shale Unit of the Benjamin Vein
Silver Tiger Metals has reported significant drill results from the Benjamin Vein, including an impressive intersection of 4,375.5 g/t silver equivalent over 2.6 meters at a depth of 119.9 to 122.5 meters. This is part of a wider mineralized interval of 15.1 meters grading 1,051.0 g/t silver equivalent in Drill Hole ET-21-272. The discovery highlights high-grade silver mineralization in the Black Shale unit of the Flat Formation, transforming Silver Tiger's exploration strategy. The company has identified this area as a new drilling target.
- Drill Hole ET-21-272 intersected 4,375.5 g/t silver equivalent over 2.6 meters.
- 15.1 meters of mineralization grading 1,051.0 g/t silver equivalent was recorded.
- Significant discovery of high-grade silver mineralization in the Black Shale unit, enhancing exploration potential.

HALIFAX, NS / ACCESSWIRE / November 30, 2021 / Silver Tiger Metals Inc. (TSXV:SLVR)(OTCQX:SLVTF) ("Silver Tiger" or the "Corporation") has intersected 4,375.5 g/t silver equivalent over 2.6 meters in the Benjamin Vein in Drill Hole ET-21-272 from 119.9 meters to 122.5 meters within a broader mineralized interval of 15.1 meters grading 1,051.0 g/t silver equivalent from 110.7 meters to 125.8 meters.
Hole ET-21-272, the most northern hole drilled to date on the Benjamin Vein, intersected a wide zone of semi-massive to massive sphalerite, galena and chalcopyrite mineralization on the footwall side of the Benjamin Vein. The sulphide mineralization is hosted in the "Black Shale" unit of the Flat Formation, an intercalated grey and black shale forming a distinct 25 to 30 meter thick sub-unit in the lower section of the Flat Formation.
Hole ET-21-272 was drilled on Section 6200N, approximately 1,300 meters to the north of the Hole ET-21-202, the "Discovery Hole" of the Sooy Vein Footwall Zone, where the sulphide mineralization was first intersected hosted in the altered black shales in the lower Flat Formation.
Highlights from Drill Hole ET-21-272 are detailed in the table below:

Silver Tiger's CEO, Glenn Jessome, stated, "The discovery of wide zones of high grade silver mineralization in the Black Shale unit of the Flat Formation surrounding the high grade quartz silver veins in the Sooy Vein, the Seitz Kelly Vein and now the Benjamin Vein located kilometers from each other is a game changing development at El Tigre. This Black Shale unit is a new target we now focus our drilling on, along with the traditional high grade silver quartz veins."

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
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 developed along strike for 1 kilometer to a depth of approximately 150 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 1932, 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 approximately 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.
