EXCELLON PROVIDES UPDATE ON OPTIMIZATION PROGRAM
AND Q1 2017 PRODUCTION RESULTS
Toronto, Ontario – April 27, 2017 – Excellon Resources Inc. (TSX:EXN and EXN.WT; OTC:EXLLF)
("Excellon" or the “Company") is pleased to provide an update on the ongoing optimization program
and announce first quarter 2017 production results from the Platosa Mine in Durango, Mexico.
Highlights
• Continued positive results from optimization program, with drawdown over past two weeks of 1.3
metres, higher than forecasted at current pumping rates
• Five of 12 submersible pumps operating, with well-cleaning and pump installation ongoing and
four additional submersibles to be installed in next two weeks
• Primary booster station running at full capacity, with second booster pump station commissioned
and ready to commence pumping this week
• Q1 2017 Production (Compared to Q1 2016)
o Silver equivalent (“AgEq”) production of 205,314 oz (Q1 2016 – 363,552 AgEq oz)
o Silver production of 108,118 oz (Q1 2016 – 211,557 oz)
o Lead production of 0.6 million lb (Q1 2016 – 1.3 million lb)
o Zinc production of 0.9 million lb (Q1 2016 – 1.6 million lb)
• Development completed during Q1 and continually drier mining conditions resulting in i mproved
grades and productivity being realized in April as operations access main body of Rodilla manto
“The Platosa optimization program is nearing completion,” stated Brendan Cahill, President and Chief
Executive Officer. “With each additional submersible pump we are increasing the local rate of drawdown
at Platosa resulting in drier mining conditions day-by-day and the results continue to confirm or exceed
our projections. Essential well cleaning was largely completed during Q1 and we are now in position to
install submersibles more rapidly. We remain on track for a dry mine by the end of Q2.”
Mr. Cahill continued, “Almost the entirety of production during Q1 came from outside of the Rodilla
manto resource area, which resulted in relatively higher dilution and lower grades, as development
focused on accessing the next level of Rodilla. Production has improved during April, with higher grades
now being mined on multiple ore faces. With the increased rate of drawdown realized from the
optimization program, we expect significantly improved production from Rodilla in Q2 and also expect to
bring the high-grade Guadalupe South manto back on line during the quarter, with development
reaching the 623 manto by the end of Q2. Despite lower than expected production in Q1, the project is
headed in the right direction.”
Optimization Program Update
As further described in the Company’s annual information form (the “AIF”), the Company has developed
an optimization program to more effectively dewater Platosa through an enhanced well -pumping
system. The optimization program will maintain and increase a localized “cone of depression” of the
water table around mine workings, ultimately resulting in dry mining conditions at Platosa. Under dry
mining conditions, the Company expects to achieve higher rates of production at lower costs relative to
current and historical production at Platosa. Refer to the AIF for a summary estimates on Platosa
production rates and costs subsequent to the completion of the optimization program.

The Company has now completed the installation of both the primary and secondary booster stations,
with the primary booster station fully commissioned and operating at full capacity and the secondary
booster station being commissioned this week and expected to be at near full capacity in the next week.
Twelve dewatering wells have been completed with five submersible pumps now installed and an
additional four planned for installation in the next two weeks. Well cleaning procedures initiated during
the first quarter have been successful and were a necessary part of ensuring the long term efficiency of
the dewatering system. Complete installation is expected during May.
Drawdown rates continue to exceed the Company’s forecasts, with a local drawdown of the water table
of 1.3 metres from April 11th-25th at an average pumping rate of 18,600 gpm, with the Company’s
original forecast expecting a drawdown of 0.85 metres over such period at that pumping rate. The
dewatering program is currently in a transitional phase from using historical pumping infrastructure to
entirely submersibles, with inflows from mining faces decreasing rapidly as the water table drops to the
level of operating faces. The deepest development heading (730 ramp at level 958) is now less than 10
metres below the water table, with production headings now less than five metres below the water
table. The Company expects pumping rates to increase rapidly in the next two weeks as a 1,000 hp
vertical pump (3,000 gpm) was taken down for maintenance last week and is currently being reinstalled
and as additional 250 hp submersibles (2,500 gpm each) come on line.

Ore production during the first quarter was primarily from the Rodilla Manto, with minimal tonnage
from the Guadalupe North and South Mantos. In Rodilla, primary working faces are in the deepest parts
of the mine and ore is below the water table, which restricted production levels during the first quarter.
Almost 90% of production from the Rodilla area during the first quarter came from the 674 heading,
outside of the Rodilla resource area. The Company extracted high-grade, though narrow mineralization
on this heading through much of the quarter with dry mining conditions. The narrow and somewhat
erratic nature of the mineralization led to increased dilution on the heading, which negatively impacted
- 3 -
grades. During the period, development focused on accessing ore faces within the Rodilla block model
and, by early April, operations were again accessing higher grade ore on multiple faces from Rodilla in
increasingly drier conditions. During the second quarter, the Company expects production will continue
from Rodilla on multiple headings, access to the Guadalupe South Manto will be regained from the 892
heading in May and development will access the 623 Manto during June from the 892 and 725 headings.
The Company expects to release first quarter financial results at market close on May 10, 2017.
