EXCELLON INCREASES PRODUCTION TO 500,763 SILVER

EQUIVALENT OUNCES IN Q3 2017

Toronto, Ontario – October 16, 2017 – Excellon Resources Inc. (TSX:EXN; TSX:EXN.WT; OTC:EXLLF)

("Excellon" or the “Company") is pleased to announce third quarter 2017 production results from the

Platosa Mine in Durango, Mexico.

Q3 2017 Production Highlights

• Material increase in production following the completion of the Optimization Plan, including:

o Silver equivalent (“AgEq”) production of 500,763 ounces, up 73% from Q2 2017 and 96%

from Q3 2016

o Silver production of 226,173 ounces, up 41% from Q2 2017 and 47% from Q3 2016

o Lead production of 1.6 million pounds, up 86% from Q2 2017 and 78% from Q3 2016

o Zinc production of 2.2 million pounds, up 95% from Q2 2017 and 86% from Q3 2016

• Production rates averaging 200 tonnes per day (tpd) vs. 125 tpd in Q2 2017

• Production headings accessed four mantos by the end of the quarter, including the high-grade 623

Manto, with further increases in production planned through the remainder of the year

“The turnaround in production at Platosa was clearly evident during the third quarter, with significantly

improved tonnage-per-day, grades and costs,” stated Brendan Cahill, President and Chief Executive

Officer. “All-in sustaining cost decreased during the quarter to approximately $11-$13 per payable silver

ounce. We are now well positioned to continue ramping up production from four mantos through the

fourth quarter and to realize a further decrease in AISC and increase in cash flow.”

Production increased during the quarter as the Optimization Plan resulted in dry mining conditions.

During July and August, production was primarily from multiple faces on the 730 heading in the Rodilla

Manto and the 795 heading in the Guadalupe South Manto. In late September, the Company accessed

the Pierna Manto and the upper part of the 623 Manto.

Development rates also increased significantly during the quarter with 269 metres of ore development

(an 84% increase over Q2 2017 – 146 metres) and 292 metres of waste development (a 39% increase

over Q2 2017 – 210 metres).

The Company is currently producing from multiple headings on the Rodilla Manto, Pierna Manto and the

connection between the Guadalupe South and 623 mantos. Development remains an essential part of

the operation and is currently driving towards the next levels of the Rodilla, Pierna, Guadalupe South

and 623 mantos, all of which are expected to yield production during Q4 2017. Development rates are

expected to continue to increase going forward.

During the second and third quarters, the Company realized exploration success from a dedicated drill

drift over the 623 Manto. That drift has been extended and further delineation drilling of the 623 Manto

will commence shortly. An additional exploration drift has been planned for the Pierna Manto, which is

expected to be completed during Q4 2017.

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:

Total: 11,934 632 13,877 752 19,953 920

During the quarter, the Company substantially completed the first stage of a new tailings management

facility (“TMF”) at the Company’s milling facility in Miguel Auza, Zacatecas, with final testing underway

and commissioning expected during October. The new TMF will provide for approximately 19 years of

capacity at a 300 tpd production rate in five stages. 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.

The Company expects to release third quarter financial results at market open on November 2, 2017.
