EXCELLON ANNOUNCES 2017 PRODUCTION RESULTS

Toronto, Ontario – January 22, 2018 – Excellon Resources Inc. (TSX:EXN, EXN.WT and EXN.WT.A;

OTC:EXLLF) ("Excellon" or the “Company") is pleased to announce fourth quarter and annual 2017

production results from the Platosa Mine, Durango, Mexico.

Highlights

• 2017 Production (compared to 2016)

o Silver equivalent (“AgEq”) production of 1.5 million oz (2016 – 1.3 million AgEq oz)

o Silver production of 718,460 oz (2016 – 752,689 oz)

o Lead production of 4.2 million lb (2016 – 4.4 million lb)

o Zinc production of 6.1 million lb (2016 – 5.6 million lb)

• Q4 2017 Production (compared to Q4 2016)

o Silver equivalent (“AgEq”) production of 475,007 oz (Q4 2016 – 305,934 AgEq oz)

o Silver production of 223,349 oz (Q4 2016 – 159,524 oz)

o Lead production of 1.2 million lb (Q4 2016 – 0.9 million lb)

o Zinc production of 1.9 million lb (Q4 2016 – 1.2 million lb)

“We made great progress in 2017,” stated Brendan Cahill, President and Chief Executive Officer. “We

removed a major bottleneck at Platosa and began ramping up production, with another solid quarter in

Q4 demonstrating stable production under dry mining conditions. We have more work to do though, as

we are working through normal course transitional issues as we ramp up to higher production rates.”

Production during the fourth quarter accessed the Rodilla Manto, Guadalupe South Manto, Pierna Manto

and the high-grade 623 Manto. During October, production was primarily from the Pierna and Guadalupe

South mantos, as ground support was required in Pierna and 623 Manto, with both mantos silled and

bolted simultaneously. Historically, intensive grouting to control water served as enhanced ground

support at great cost and time. With grouting eliminated, the operation is incorporating normal course

bolting and screening at much lower cost and time to advance development. Tonnage improved

considerably during the remainder of the quarter with multiple operating faces in all four mantos. More

efficient installation of ground support is a key ongoing project at Platosa, as the mining operation works

to increase productivity to reach a steady rate of production at 300 tonnes per day (“tpd”).

Pumping rates were lower than planned during Q4 2017, which impacted overall drawdown, as repairs

were required on the electrical starters on certain pumps, but are expected to return to over 30,000 gpm

in the coming weeks. Drawdown was also impacted by refiltration of water from surface into the aquifer

from two areas identified during Q4, which have now been closed off. By the end of Q4, drawdown rates

were returning to expectation and the Company anticipates continued improvement in Q1 2018. Due to

the foregoing, development rates were lower than the previous quarter with 151 metres in ore (44%

decrease over Q3 2017 – 269 metres) and 227 metres in waste (22% decrease over Q3 2017 – 292 metres).

Development rates are expected to continue to increase as headings drive into the next levels of all four

mantos.

During the quarter, the Company continued to process low-grade historical stockpiles and sump material,

with minimal associated mining cost. This mineralized material is blended with mined ore to improve

payability, as well as being cash flow generative. The following table sets out the mix of ore and low grade

stockpiles processed year-to-date, demonstrating the increase in AgEq grades as the year progressed:

In October, the Company successfully commissioned the second tailings management facility (“TMF”) at

the Company’s milling facility in Miguel Auza, Zacatecas. The new TMF will provide for approximately 19

years of capacity at a 300 tpd production rate in five stages and replaces the original TMF which had

reached its design capacity. The TMF is a key strategic asset in the Company’s plans to (i) continue growing

resources at the Platosa Mine, (ii) discover additional Platosa-like deposits on the Platosa Property, and

(iii) discover epithermal silver deposits in the Miguel Auza area.

During 2017, the Company accelerated underground drilling and successfully added material amounts of

mineralization to the upper parts of the 623 Manto. The Company is currently revising the Platosa mine

plan to incorporate this near-infrastructure and near-term-mineable mineralization and will provide an

update on 2018 guidance in due course. The Company also expects to release an updated mineral resource

estimate for Platosa in the coming months.

The Company expects to release fourth quarter and annual financial results at market open on March 22,

2018.

Exploration Update

In mid-December 2017, the Company commenced an extensive surface exploration program on the

21,000-hectare Platosa Property with 30,000 metres of diamond drilling planned. One drill rig is currently

operating on surface, focussed on discovering new manto mineralization along the prospective Platosa

Corridor (see press release dated December 14, 2017 for further information). Drilling also continues

underground to define mineralization near existing infrastructure and around the high grade 623 Mantos,

with additional underground results expected in the coming weeks.

Conversion of Outstanding Convertible Debentures

The Company is also pleased to announce that the accelerated conversion of all remaining outstanding

3.75% convertible debentures due November 27, 2019 was completed on December 28, 2017.

Accordingly, the Company issued 9,695,000 Common Shares at a price of $0.50 per share and cleared all

outstanding debt from the balance sheet.

“Our debentureholders allowed us to commence the optimization of Platosa during much less favourable

equity and commodity markets. We are thankful for their trust and support at that time and for their

further participation in recent equity financings. We look forward to having them as shareholders for many

years to come.”

Qualified Persons

Mr. Denis Flood, P. Eng., Vice-President Technical Services, has acted as the Qualified Person, as defined

mineralization on the Platosa Project and epithermal silver mineralization on the Miguel Auza Property

and capitalizing on the opportunity in current market conditions to acquire undervalued projects in the

Americas.
