EXCELLON REPORTS LABOUR ACTION AT PLATOSA

Toronto, Ontario – March 7, 2022 – Excellon Resources Inc. (TSX:EXN, NYSE:EXN, FRA:E4X2) (“Excellon”

or the “Company”) reports that the Sindicato Nacional Minero Metalúrgico (the " Platosa Union") has

commenced a labour action at the Platosa Mine in Durango, Mexico.

“We have had a constructive relationship with the Platosa Union for many years and earlier last week we

had agreed in principle on the terms of the 2022 collective bargaining arrangement following numerous

concessions,” stated Brendan Cahill, President and CEO. “Unfortunately, the agreement was reneged on

and, despite our additional concessions, a labour action was ordered. Our workers at Platosa have one of

the most generous compensation structures in the Mexican mining industry and have benefitted greatly

from both improved metal prices and improved productivity in recent years. We hope they also

understand the challenges we are facin g this year at Platosa. As always, we continue to remain open to

discussions and hope for a positive resolution in the near term.”
