EXCELLON
ANNOUNCES EXTENSION OF BRÄUNSDORF LICENSE
ON SILVER CITY PROJECT

Toronto,
Ontario – June 9, 2022 – Excellon Resources Inc. (TSX:EXN, NYSE:EXN, FRA:E4X2) (“Excellon” or the “Company”)
is pleased to announce the extension to September 30, 2025 of the 164 km² Bräunsdorf exploration license (the “Bräunsdorf
License”), composing part of the 340 km² Silver City Project in Saxony, Germany.

“The
Bräunsdorf License was the first piece of our Silver City Project and has been the primary focus of our exploration efforts since
we arrived in Saxony in Q3 2019,” stated Brendan Cahill, President & CEO. “Our drilling programs on the license have
delineated a high-grade epithermal silver system over tens of kilometres, that remains open with multiple targets yet to be followed
up on and the new licenses we acquired last year yet to be explored. We also continue to be impressed by the regulatory efficiency of
the jurisdiction and remain committed to Saxony for the foreseeable future. Finally, Globex Mining has been a great partner on the Bräunsdorf
License and we look forward to earning a 100% interest in the license in Q3 this year.”

Excellon
is earning into a 100% interest in the Bräunsdorf License pursuant to an option agreement (the “Option Agreement”) dated
September 23, 2019 (as amended) between the Company’s subsidiary, Saxony Silver Corp., and Globex Mining Enterprises Inc. (TSX:GMX,
OTCQX:GLBXF and FRA:G1MN) (“Globex”). The remaining components of consideration under the Option Agreement are:

Excellon
has also agreed to make a one-time C$300,000 payment upon the release of a maiden resource on the Bräunsdorf License and a one-time
payment of C$700,000 upon the achievement of commercial production from the Bräunsdorf License.

The
340 km² Silver City Project is located within a large, high-grade epithermal system and has a long history of mining dating
back to the 12th century, with no modern-day exploration for precious metals.

About
Excellon

Excellon’s
vision is to create wealth by realizing strategic opportunities through discipline and innovation for the benefit of our employees, communities
and shareholders. The Company is advancing a precious metals growth pipeline that includes: Platosa, a high-grade silver mine producing
in Mexico since 2005; Kilgore, an advanced gold exploration project in Idaho with strong economics and significant growth and discovery
potential; and an option on Silver City, a high-grade epithermal silver district in Saxony, Germany with 750 years of mining history
and no modern exploration. The Company also aims to continue capitalizing on current market conditions by acquiring undervalued projects.
