EXCELLON ANNOUNCES Q4 AND ANNUAL 2021 PRODUCTION RESULTS

Toronto, Ontario – January 17, 202 2 – Excellon Resources Inc. (TSX:EXN; NYSE:EXN and FRA:E4X2)

("Excellon" or the “Company") is pleased to announce Q4 and annual 2021 production results from the

Platosa Mine in Durango, Mexico.

2021 Production (compared to 2020)

• Silver equivalent (“AgEq”) production increased 25% to 2.0 million oz (2020 – 1.6 million AgEq oz),

including:

o Silver production increased 20% to 1.2 million oz (2020 – 1.0 million oz)

o Lead production increased 17% to 7.6 million lb (2020 – 6.5 million lb)

o Zinc production increased 20% to 9.0 million lb (2020 – 7.5 million lb)]

Q4 2021 Production (compared to Q4 2020)

• AgEq production decreased 12% to 492,013 oz (Q4 2020 – 556,332 AgEq oz), including:

o Silver production decreased 24% to 271,525 oz (Q4 2020 – 355,581 oz)

o Lead production decreased 23% to 1.7 million lb (Q4 2020 – 2.2 million lb)

o Zinc production decreased 12% to 2.2 million lb (Q4 2020 – 2.5 million lb)

“Our Mexican operations delivered records for mined and processed tonnage in 2021, along with the most

silver ounces produced since 2013,” stated Brendan Cahill, President and CEO. “During Q4, we realized

lower production than the very strong Q4 2020 quart er, primarily due to lower ore grades and partially

due to seasonal impact s on processing and delivery schedules. At Platosa, we continue work to assess

2022 mine plans and outlook.”

of concentrates.

Consistent throughput continued in Q4 2021, the sixth consecutive quarter of over 20,000 tonnes mined

and milled from Platosa following the restart of operations in late Q2 2020. Comparative prior-year results

for the year ended December 31, 2020 were impacted by the suspension of operations in Mexico from

April 2, 2020 to June 1, 2020 pursuant to the Mexican presidential order to mitigate the spread of COVID-

19.

Head grades were lower in Q4 2021 compared to Q 4 2020 due to higher mining dilution in narrower

sections of the ore body and variation in manto mineralization. Silver and lead recoveries were lower due

to lower metal feed grades and flotation performance, while zinc recoveries improved in Q4 2021.

As referenced on January 5, 2022, Excellon continues to assess whether maintaining a consistent

production schedule at the Platosa Mine is feasible beyond mid-2022 at achievable dewatering rates and

with acceptable capital expenditures.

COVID-19 Update

Excellon continues to benefit from robust measures to prevent COVID -19 among the workforce and to

monitor the effectiveness of these measures in mitigating any potential impact on business activities. The

Company’s actions have been successful to date and the pandemic has not had any material impa ct on

production or shipment of concentrate. Vaccination programs have progressed well, with 100% and over

96% of the Company’s workforce in Mexico having received first and second vaccinations, respectively.

Until recently, the omicron variant of COVID was less prevalent in Mexico than elsewhere, but case counts

have increased across the country and in communities near the Company’s operations. To date, no serious

cases have been encountered in the Company’s workforce and there has been no impact on the

operations. The Company continues to monitor the situation closely and has personnel and operating

contingency plans in place to manage daily operations.

Paul Keller, P. Eng., has acted as the Qualified Person, as defined in NI 43-101, with respect to the disclosure
