Underground Drilling At The Platosa Mine In Durango

TORONTO - Excellon Resources Inc. reported results from underground drilling at the Platosa Mine in Durango, Mexico. Further high-grade results from the 623, NE-1S, and Guadalupe South mantos, with diamond drilling results from underground including: 2,860 g/t silver equivalent ("AgEq") over 7.5 meters (1,570 g/t Ag, 10.4% Pb, 29.6% Zn and 0.1 g/t Au) and 667 g/t AgEq over 2.5 meters (479 g/t Ag, 4.6% Pb and 2.0% Zn) in EX21UG690; 2,009 g/t AgEq over 3.1 meters (1,214 g/t Ag, 8.3% Pb and 16.9% Zn) in EX21UG687; 5,574 g/t AgEq over 0.8 meters (5,052 g/t Ag, 18.4% Pb, 1.3% Zn and 0.1 g/t Au) in EX21UG641; 742 g/t AgEq over 4.8 meters (391 g/t Ag, 6.6% Pb and 5.3% Zn) in EX21UG633; and 5,432 g/t AgEq over 0.6 meters (5,012 g/t Ag, 15.8% Pb, 0.4% Zn and 0.1 g/t Au) in EX21UG673. Underground drilling continues to define and delineate mineralization for 2021 and 2022 production, and potential new zone of high-grade mineralization discovered in EX21UG690 below historically mined zone in Guadalupe South, with upcoming drilling to test vertical attitude and extent.

"Drilling at Platosa continues to define high-grade mineralization ahead of production," said, Ben Pullinger, Senior Vice President Geology & Corporate Development. "With EX21UG690, we have potentially discovered a new zone of very high-grade mineralization sitting below the historically mined upper part of the 623 Manto. This mineralization is located approximately 80 meters above the deepest current development heading and appears to have a vertical attitude that was not tested in historical drilling. Follow-up drilling to test this zone is an immediate priority of the ongoing drill campaign."
