EXCELLON PROVIDES UPDATE ON OPTIMIZATION PROGRAM

AND 2016 PRODUCTION RESULTS

Toronto, Ontario – January 31, 2017 – Excellon Resources Inc. (TSX:EXN and EXN.WT; OTC:EXLLF)

("Excellon" or the “Company"), Mexico’s highest grade silver producer, is pleased to provide an update

on the ongoing optimization program and announce fourth quarter and annual 2016 production results

from the Platosa Mine in Durango, Mexico.

Highlights

• Initial pumping results from ongoing optimization program exceeded expectation, well drilling on

schedule and submersible pump calibration underway

• 2016 Production (Compared to 2015)

o Silver equivalent (“AgEq”) production of 1.3 million oz (2015 – 1.4 million AgEq oz)

o Silver production of 752,689 oz (2015 – 794,289 oz)

o Lead production of 4.4 million lb (2015 – 4.4 million lb)

o Zinc production of 5.6 million lb (2015 7.4 million lb)

• Q4 2016 Production (Compared to Q4 2015)

o Silver equivalent (“AgEq”) production of 305,934 oz (Q4 2015 – 259,885 AgEq oz)

o Silver production of 159,524 oz (Q4 2015 – 152,628 oz)

o Lead production of 0.9 million lb (Q4 2015 – 0.8 million lb)

o Zinc production of 1.2 million lb (Q4 2015 – 1.3 million lb)

“The Company’s optimization program at Platosa is progressing well, with submersible pumps coming

online by year-end 2016 and initial pumping results far exceeding our expectations,” stated Brendan

Cahill, President and Chief Executive Officer. “With the first two submersibles started, we achieved over

one metre of drawdown in the first week of operation, far beyond forecast and yet further proof of the

project’s efficacy. Well drilling continues on schedule, with nine of fourteen wells now complete and

ready for pump installation. We are currently calibrating the well set-up for installed submersibles to

ensure sustained pumping operations going forward and remain on track to complete the

implementation by the end of Q1 and attain dry mining conditions during Q2.”

Mr. Cahill continued, “Production during Q4 improved over Q3 2016 and Q4 2015 from both tonnage and

ounce perspectives. We are currently mining on the fringes of the Rodilla Manto as water management

has resulted in slower progress through the deeper but higher-grade core of Rodilla, and development

continues into the 623 Manto. Looking forward in 2017, we expect material improvement in production

during Q2 and the ongoing optimization work to be fully reflected in the second half of the year.”

Optimization Program Update

The Company is also pleased to provide an update on the ongoing optimization program at Platosa. As

further described in the Company’s annual information form (the “AIF”), the Company has developed an

optimization program to proactively dewater Platosa through an enhanced well-pumping system. The

optimization program aims to maintain and increase a localized “cone of depression” of the water table

below mine workings, ultimately resulting in completely dry mining conditions at Platosa. Under dry

mining conditions, the Company expects to achieve materially higher rates of production at materially

lower costs relative to current and historical production at Platosa. Refer to the AIF for a summary of

- 2 -

www.excellonresources.com estimates on Platosa production rates and costs subsequent to the

completion of the optimization program. Also refer to the Company’s press release dated October 27,

2016 for a summary of the installation process for the dewatering system.

In December 2016, the Company completed the installation and testing of the primary booster station

(comprising four 600hp pumps) in Guadalupe South. The Company also completed installation of two

additional 250hp submersible pumps in Guadalupe South. The initial results from these wells far

exceeded expectations, with the drawdown over the succeeding week in excess of one metre,

approximately 150% greater than expected. The Company has encountered certain technical challenges

with pump reliability and sustainable operation due to rock chips and drill cuttings in the wells. These

challenges are currently being remedied through well-cleaning and pump screening, and the Company

expects to continue pump installation and enhanced pumping operations in the coming days/weeks.

Well drilling remains on schedule, with nine of fourteen wells now ready for pump installation and drilling

expected to be completed during March. The project remains on budget and the Company expects to

complete installation by the end of Q1 2017, with dry mining conditions being achieved during Q2 2017.

Further updates on the progress of this program will be provided regularly during the implementation

period.

Ore production during the fourth quarter was primarily from the Rodilla Manto and Guadalupe North and

South Mantos. In Rodilla, primary working faces are in one of the deepest parts of the mine and ore is

below the water table. Though these areas are effectively dry and water inflows are entirely under

control, development and production conditions continue to be challenging. Significant production during

the quarter came from the fringes or outside of the block model of the Rodilla Manto, resulting in higher

dilution in some cases and lower grades. Mining conditions are expected to materially improve in the

- 3 -

coming months as the pending increase in drawdown rate more rapidly closes the gap between the water

table and operating elevations.

During the period development was impacted by water conditions, but continues to be a priority for the

Company as it moves into the higher grade areas of the mine including the 623 Manto, hosting mineral

resources of 83,000 tonnes at 1,232 g/t Ag (1,777 g/t AgEq).

The Company expects to release third quarter financial results prior to market open on March 23, 2017.
