Excellon Resources Inc. announced drill results from its ongoing underground exploration program at the Platosa Mine in Durango, Mexico, along with an update on third quarter2018 production. Further definition and expansion of the 623 Manto, with diamond drilling results including: 1,700 g/t Ag, 15.4% Pb, 21.4% Zn and 2.9 g/t Au or 3,613 g/t silver equivalent ("AgEq") over 5.5 metres in EX18UG434, including 1,326 g/t Ag, 12.6%Pb, 25.3% Zn and 7.5 g/t Au or 3,655 g/t AgEq over 2.0 metres; and 1,014 g/t Ag, 10.9% Pb, 26.0% Zn and 0.4 g/t Au or 2,781 g/t AgEq over 15.1 metres in EX18UG435. Expansion and infill of the lower Rodilla Manto, including: 397 g/t Ag, 2.6% Pb, 4.1% Zn and 0.1 g/t Au or 714 g/t AgEq over 10.5 metres in EX18UG411, including 775 g/t Ag, 4.8% Pb, 7.8% Zn and 0.1 g/t Au or 1,362 g/t AgEq over 5.1 metres; and 783 g/t Ag, 8.2% Pb, 11.1% Zn and 0.4 g/t Au or 1,708 g/t AgEq over 2.7 metres in EX18UG420. These results incorporate drilling from the Martillo and 822-2 drill stations, which were developed to expand and define mineralization at the Rodilla, NE-1S and 623 mantos. These results were not included in the Company's updated Mineral Resource Estimate filed on September 7, 2018 (which included drill results up to March 31, 2018) and represent the potential for additional mineral resources. Drilling at the 623 Manto is of particular interest, with a zone of gold enrichment running northeast along the main axis of the 623 Manto. This zone is thought to represent a "hotter" zone of mineralization within the manto, which could be related to the genesis of the Platosa mantos. Further work is planned for this area. Platosa drill core samples are prepared and assayed by SGS Minerals Services in Durango, Mexico. The lab is accredited to ISO/IEC 17025. The Company has a comprehensive QA/QC program, supervised by an independent Qualified Person. Surface drilling continues at Platosa with a drill rig currently testing targets in the same horizon that hosts the Platosa Mine within the north-south trending Platosa corridor. The Company intends to continue testing priority targets within this corridor while continuing to define new targets at Jaboncillo, PDN, Saltillera North and South and San Gilberto through its ongoing fieldwork program.

The Company anticipates production in the quarter to be approximately 300,000 AgEq ounces due to operational issues related to surveying and planning personnel and lower byproduct prices. The operational issues have now been addressed and the operation is getting back on track. The Company's balance sheet remains strong, which will allow the Company to weather recent dips in commodity prices and quarterly production variability.
