EXCELLON PROVIDES UPDATE ON KILGORE GOLD PROJECT

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

or the “Company”) reports that the Idaho Conservation League and Greater Yellowstone Coalition (the

“ICL/GYC”) have filed a legal action (the “Action”) in U.S. District Court challenging the recent United States

Forest Service (“USFS”) approval of a Plan of Operations submitted by Excellon’s subsidiary, Excellon Idaho

Gold Inc. (“Excellon Idaho Gold”) , concerning the Kilgore Gold Exploration Project in the Dubois Ranger

District, Clark County, Idaho. The Action follows the denial by the U.S. District Court of a motion filed by

the ICL/GYC to reopen the 2018 proceeding against the USFS.

“The filing of this Action was entirely expected and we are confident that the work performed by the USFS

on the Environmental Assessment over the past two years will withstand the challenge in Court,” stated

Brendan Cahill, President & CEO of Excellon. “The U.S. District Court recently rejected a motion by the

ICL/GYC to reopen the 2018 proceeding and we are confident the Court will reject ICL/GYC’s claims in this

Action.”

In response to the Court’s previous decision in 2020, the USFS supplemented its analysis of water quality

in the Dog Bone Ridge area and potential impacts on Yellowstone cutthroat trout. A USFS biological

evaluation determined the exploration project’s activities will have no impact on the Yellowstone

cutthroat trout and its habitat. In addition to actions taken in response to the Court’s previous decision,

the USFS updated analyses of terrestrial, aquatic, and plant species known or expected to occur within

the project area during its Environmental Assessment. The Environmental Assessment and De cision

Notice/Finding of No Significant Impact are available on Excellon Idaho Gold’s website:

Excellon Idaho Gold expects to file a motion to intervene as a defendant-intervenor to protect its interests

in the matter.
