­­­­­­­­­­­Toronto, Ontario – December 5, 2019 – Excellon Resources Inc. (TSX:EXN, EXN.WT, OTC:EXLLF and FRA:E4X1) ("Excellon" or the “Company") is providing an update to shareholders on the previously disclosed ongoing legal action in Mexico in respect of the La Antigua mineral concession (“La Antigua”) that is part of the Evolución Property in Zacatecas. La Antigua was included in Excellon’s acquisition of Silver Eagle Mines Inc. (“Silver Eagle”) in 2009, which includes a portion of the historic mineral resource at Miguel Auza. The concession is subject to an exploration and exploitation agreement with purchase option (the “Agreement”) dated December 3, 2006 between San Pedro Resources SA de CV (“San Pedro”, now a subsidiary of Excellon) and the owner (the “Plaintiff”) that provides, among other things, for a minimum payment of US$2,500 plus value added tax per month (the “Advance Royalty”) and the payment of a 3% net smelter return (“NSR”) royalty. San Pedro has the right to purchase absolute title to La Antigua including the NSR royalty upon payment of US$500,000. San Pedro has accrued the Advanced Royalty on an ongoing basis and the Agreement remains in force.

Though the Miguel Auza Mine never reached commercial production and was put on care-and-maintenance in December 2008 prior to Excellon’s acquisition of Silver Eagle, the Plaintiff sued San Pedro for non-compliance with the Agreement and specifically for not operating the Miguel Auza Mine. As disclosed in Excellon’s management discussion and analysis, the Plaintiff was awarded damages of approximately $0.7 million in the court of first instance in Torreón, Coahuila. Both San Pedro and the Plaintiff appealed the decision to the Second District State Court in the Judicial District of Torreón. That Court confirmed the initial decision but, subsequently, pursuant to an order obtained by the Plaintiff, granted the Plaintiff an award of approximately US$23 million, predominantly in damages for the Miguel Auza Mine not being in operation. San Pedro is appealing this decision to the federal courts of Mexico and believes that the decision is without merit and not supported by the evidence, facts or law.       

“We will vigorously appeal this erroneous decision,” stated Brendan Cahill, President and CEO. “The Miguel Auza Mine never reached commercial production or generated revenues before it was put on care-and-maintenance by Silver Eagle in 2008. The Agreement with the Plaintiff clearly provides for an advance royalty payment in the event that the mine is not producing and, in fact, the currently disputed award is multiple times greater than any income the NSR royalty could possibly produce. We expect this decision to be reversed and rationalized in the federal court system. In the interim, we do not expect any impact on Excellon’s ongoing business activities.”
