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 Decision Notice/Finding of No Significant Impact are available on Excellon Idaho Gold’s website: https://excellonidaho.com

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