Toronto, Ontario – October 23, 2019 – Excellon Resources Inc. (TSX:EXN, EXN.WT, OTC:EXLLF and FRA:E4X1) (“Excellon” or the “Company”) is pleased to announce third quarter 2019 production results from the Platosa Mine in Durango, Mexico.

Q3 2019 Production (compared to Q3 2018)

• Silver equivalent (“AgEq”) production of 427,131 oz (Q3 2018 – 300,766 AgEq oz)
  • Silver production of 257,497 oz (Q3 2018 – 171,227 oz)
  • Lead production of 1.3 million lb (Q3 2018 – 0.8 million lb)
  • Zinc production of 1.7 million lb (Q3 2018 – 1.0 million lb)

“We are ahead of where we were after three quarters in 2018, despite lower base metal prices, but we continue to have further work to do at both Platosa and Miguel Auza,” stated Brendan Cahill, President and Chief Executive Officer. “Production did not meet our expectations in Q3 2019 due to lower than planned metal recoveries at our Miguel Auza processing facility and delayed processing of ore stockpiles and delivery of concentrate inventory at quarter-end relative to Q2 2019. The delay in ore processing and concentrate delivery will result in higher all-in sustaining costs during the quarter relatively to recent quarters. That said, production at Platosa continued at a good pace with ongoing efforts to reduce dilution proving successful. Our focus going forward is to continue improving production rates at Platosa while effectively implementing flow sheet upgrades at Miguel Auza to drive down costs.”
