EXCELLON ANNOUNCES Q1 2020 PRODUCTION RESULTS

Toronto, Ontario – April 30, 20 20 – Excellon Resources Inc. (TSX:EXN, EXN.WT, OTC:EXLLF and

FRA:E4X1) ("Excellon" or the “Company") is pleased to announce first quarter 2020 production results

from the Platosa Mine in Durango, Mexico.

Q1 2020 Production (compared to Q1 2019)

• Silver equivalent (“AgEq”) production of 523,742 oz (Q1 2019 – 522,261 AgEq oz)

o Silver production increased 14% to 296,281 oz (Q1 2019 – 260,445 oz)

o Lead production increased 37% to 1.9 million lb (Q1 2019 – 1.4 million lb)

o Zinc production decreased 4% to 2.1 million lb (Q1 2019 – 2.2 million lb)

“We had a strong start to the year with production improving from previous quarters,” stated Brendan

Cahill, President and CEO. “Silver and lead production, in particular, were significantly higher than recent

quarters. Unfortunately, our base metal production contributed fewer silver equivalent ou nces due to

current prices. During the ongoing suspension of operations mandated by the government of Mexico,

we are implementing a number of business improvement initiatives including preparing for the switch to

a private electrical energy provider, review ing maintenance programs, designing an underground

communications system to optimize the dewatering system and implementation of a new ERP system.

We expect these initiatives will drive further cost efficiencies on the restart of operations.”

** AgEq ounces established using average realized metal prices during the period indicated applied to the recovered metal content of

concentrates.

Production during Q1 2020 accessed multiple ore faces in the Rodilla, 623, Guadalupe and Pierna

mantos with improved grades for silver and lead. Zinc grades were more variable than expected due to

grade variability among the four mantos.

While silver and lead recoveries continued to improve, zinc recoveries were impacted by ongoing

adjustments designed to stabilize mill performance , including the use of different reagents to optimize

recoveries of all three metals.

COVID-19 Update

The Mexican Federal Government has extended the suspension of all non -essential activities until

May 30, 2020 to slow the spread of COVID -19. The directive also includes a potential restart of activities
