EXCELLON DRILLS 3,428 G/T SILVER EQUIVALENT
OVER 10.2 METRES AT PLATOSA
Toronto, Ontario – May 31, 2018 – Excellon Resources Inc. (TSX:EXN, EXN.WT, EXN.WT.A; OTC:EXLLF)
("Excellon" or the “Company") is pleased to announce additional results from its ongoing underground
exploration program at the Platosa Mine in Durango, Mexico, which continues to identify near-term
mineable mineralization with the aim of growing Platosa mineral resources.
Highlights
• High-grade results from existing mantos include:
o 1,153 g/t Ag, 8.2% Pb and 3.4% Zn or 1,662 g/t silver equivalent (“AgEq”) over 5.3
metres in EX18UG376 from 623 Manto
o 2,148 g/t Ag, 19.2% Pb and 9.7% Zn or 3,428 g/t AgEq over 10.2 metres in EX18UG394
from Pierna Manto
o 870 g/t Ag, 13.3% Pb and 12.4% Zn or 2,034 g/t AgEq over 6.7 metres in EX18UG398
from Pierna Manto
“As with our previously announced results, drilling underground continues to increase our confidence in
the resources and expand our footprint at Platosa,” stated Ben Pullinger, Senior Vice-President Geology.
“Definition drilling ahead of current mine workings allows for continued de-risking of future production
allowing for better visibility on planning. In particular, the widths intersected in the Pierna Manto are
better than expected or predicted in the current resource model.”

(1) From-to intervals are measured from the drill collar, with drill holes marked UG or PH drilled from underground stations.
(2) All intervals are reported as core length.
(3) AgEq in drill results assumes $17.00 Ag, $1.03 Pb and $1.23 Zn with 100% metallurgical recovery.
The results announced today from the 623, Rodilla and Pierna mantos complement underground drilling in
the 623 and Guadalupe South connector/expansion zone completed in 2017, 2018 and late 2016 (see press
releases dated October 27, 2016, July 26, 2017, September 6, 2017 and February 22, 2018).
Drilling underground is focused on defining the open area between the Pierna and Rodilla Mantos and
better defining the extension to depth of all mantos ahead of future production. The Company is currently
producing from the 623, Pierna and Rodilla mantos.
The Company is in the process of finalizing an updated mineral resource estimate and technical report,
which will incorporate drilling completed up to December 31, 2017. Finalizing the resource has taken
longer than originally anticipated as optimizations to the resource model and mine plan were identified
and are being incorporated. The updated resource estimate is currently expected to be released prior to
the end of Q2 2018.
Platosa drill core samples are prepared and assayed by SGS Minerals Services in Durango, Mexico. The lab
is accredited to ISO/IEC 17025. The Company has a comprehensive QA/QC program, supervised by an
independent Qualified Person.
Surface Exploration Update
Surface drilling continues at Platosa with two drill rigs currently testing targets in the same target horizon
that hosts the Platosa Mine within the north-south trending Platosa corridor. The Company intends to
continue testing priority targets within this corridor, while continuing to define new targets at Jaboncillo,
PDN, Saltillera and San Gilberto through its ongoing fieldwork program.
The Company is also currently completing an induced polarization (IP) survey on key targets at the Miguel
Auza Property ahead of upcoming drilling late in Q2 or early in Q3 2018.
Qualified Person
Mr. Ben Pullinger, P. Geo, Senior Vice-President Geology, has acted as the Qualified Person, as defined in
NI 43-101, with respect to the disclosure of the scientific and technical information relating to exploration
results contained in this press release.
