Silver Elephant Finds Large Geophysical Anomaly 300 Meters North of Tajo Vein at Pulacayo Silver Project, Drilling to Commence in July

VANCOUVER, May 20, 2021 - Silver Elephant Mining Corp. ("Silver Elephant" or "the Company") (TSX:ELEF)(OTCQX:SILEF)(Frankfurt:1P2N) announces that based on Induced Polarization (IP) geophysical survey results, the Company has identified a large linear anomaly measuring over 1,400 meters in length, up to 250 meters wide, starting at a depth of approximately 250 meters from surface at its Pulacayo silver project in Potosi department, Bolivia.

The entire length of the anomaly has never been drilled and shows very high and consistent chargeability and low resistivity and runs parallel to the main 3 km east-west trending Tajo vein system (TVS) that is just 300 meters to the south.

Reviewing the size, the location and geological setting, the Company believes one possibility explaining the anomaly may be that it is an off-shoot vein originating from a much deeper level, that forks off the main Tajo vein.

According to historic mine records, portions (averaging 500+ g/t silver and 10%+ lead and zinc) of the Tajo vein have been mined to a depth of 1,000 meters between 1800's and 1952. Mining by Hochschild Group yielded historic production of 670 million silver oz's according to detailed mine records, which have been digitized and analyzed by the Company.

Joaquin Merino, VP South America Operation comments: "We were very surprised by how large and how close the anomaly is to the Tajo vein. The Hochschild mine records indicate that their miners were focusing only on lateral and vertical development of the Tajo vein. It was a very successful endeavor until the mine was stopped at its deepest level by Bolivian National Revolution in 1952. Silver Elephant will drill and test the IP anomaly which may represent a parallel or conjugate system to the Tajo vein."

In October 2020, the Company announced a mineral resource estimate on the project of a combined 107 million oz's of silver in the indicated category all within the upper portion of the Pulacayo TVS and Paca deposits according to the Mercator Geological Services technical report dated October 13^th, 2020, now available at sedar.com. This estimate is based on over 100,000 meters of drilling. None of this drilling has reached beyond 500 meters vertical depth from surface.

The IP survey program is being conducted by Matrix Geotechnologies Ltd. of Canada and overseen by Danniel Oosterman and Joaquin Merino, both Qualified Persons according to NI 43-101 (refer to news release dated January 27, 2021). The program consists 110 line-kilometers which overlay the Pulacayo, Pacamayo, El Abra, Pero, and Paca areas at 100-meter line spacing. The Company is receiving survey raw data which it is compiling and interpreting continually. The geophysical technical ground crew is scheduled to complete IP survey in July, while the drill crew is mobilizing and expected to commence drilling in July.
