Toronto, Ontario--(Newsfile Corp. - March 28, 2024) - Excellon Resources Inc. (TSX: EXN) (OTCQB: EXNRF) (FSE: E4X2) ("Excellon" or the "Company") is pleased to announce that it has closed its previously announced restructuring of the outstanding 5.75% secured convertible debentures of the Company (the "Debentures") to reduce the outstanding principal amount of the Debentures to C$7.5 million, representing a 58% reduction in principal, and to amend the terms of the remaining Debentures (collectively, the "Debenture Restructuring").

Shawn Howarth, President and CEO, commented, "The Debenture Restructuring is a significant first step towards equity growth for Excellon shareholders. The reduction and extension of the remaining Debentures provides our shareholders with increased exposure to a high quality gold project at Kilgore, and an emerging European-focused silver exploration opportunity at Silver City."

Debenture Repurchase

The Company has completed the repurchase for cancellation of C$10,410,000 aggregate principal amount of the Debentures (the "Debenture Repurchase") pro rata from the holders of the Debentures in exchange for the following aggregate consideration divided pro rata among the holders of the Debentures:

• 38,888,878 common shares in the capital of Excellon ("Common Shares");

• contingent value rights of Excellon, providing for aggregate cash payments equal to the equivalent of up to 1,500 troy ounces of gold upon the achievement of certain milestones;

• a 2% net smelter returns royalty on the unpatented claims comprising the Kilgore Project; and

• a 25% interest in Saxony Silver Corp., which holds the Silver City Project.

Additionally, in connection with the Debenture Repurchase, the Company issued 2,846,147 Common Shares in satisfaction of accrued and unpaid interest on the Debentures to, but excluding, the date of the Debenture Repurchase.

Registered holders of the Debentures will receive a notice regarding the Debenture Repurchase and are advised to read the notice carefully as it contains important instructions on how to receive the consideration for the Debenture Repurchase to which they are entitled.
