Excellon Intersects 2,481 g/t Silver Equivalent Over 3.0 Metres at Platosa

Excellon Resources Inc. (TSX: EXN) (TSX: EXN.WT) (OTC: EXLLF) (“Excellon” or the “Company”), Mexico’s highest grade silver producer, is pleased to announce results from its ongoing surface and underground exploration program at the Platosa Mine in Durango, Mexico.

Highlights

• Discovery of extensions to 6A and Guadalupe North Mantos in which three distinct zones of mineralization were discovered above the water table. The first of the three zones is currently being mined, with 1,107 tonnes extracted in January. Results from EX16UG281 include:
  • 686 g/t Ag, 4.69% Pb and 6.18% Zn or 1,193 g/t Ag Equivalent (“AgEq”) over 2.4 metres;
  • 504 g/t Ag, 4.33% Pb and 7.08% Zn or 1,041 g/t AgEq over 2.0 metres;
  • 843 g/t Ag, 0.41% Pb and 0.02% Zn or 861 g/t AqEq over 1.2 metres;
• High grade intersection of 795 g/t Ag, 9.25% Pb and 25.85% Zn or 2,481 g/t AgEq over 3.0 metres in EX16LP1107, representing an increased footprint of mineralization north of the Pierna Manto, to be accessed in late 2017; and
• 2017 drill program to focus on drilling extensions and gathering important structural information related to controlling structures for the Rodilla and Pierna Mantos and expanding the mineral footprint of the Guadalupe South, NE1 and high-grade 623 mantos.
  * AgEq in drill results assumes $16.80 Ag, $1.03 Pb and $1.23 Zn with 100% metallurgical recovery.

“Recent drilling results confirm our ability to discover additional high-grade manto mineralization both near surface and around our existing resource,” stated Ben Pullinger, Vice-President, Geology. “The discovery of a connector zone between the Guadalupe North and 6A Mantos is very encouraging and provides more flexibility in our mine plans and allows us to open up new headings closer to surface.”

Exploration Results

The Company commenced a 25,000-metre diamond drilling exploration program in Q3 2016. This program encompasses drilling from surface and from underground and is currently focused on defining additional shallow mineralization located near existing infrastructure in mineable areas.

Additional highlights from the program include:

• 662 g/t Ag, 4.9% Pb, 25.5% Zn and 0.57 g/t Au or 1,886g/t AgEq over 13.00 metres in EX16UG274,
• 773g/t Ag, 11.8% Pb and 6.3% Zn or 1,438g/t AgEq over 2.77 metres in PH16-13

To date, 5,400 metres have been completed accounting for 35 holes from surface and underground. Material intersections are summarized below:

Drilling through this period has focused on definition and growth of the existing resource in areas that will be in production in 2017 as well as exploring for new manto mineralization above the water table in areas accessible from existing workings.

Diamond drill holes EX16LP1107 and 1108 were successful in increasing the footprint of the Rodilla and Pierna Mantos with 1107 intersecting 795 g/t Ag, 9.25% Pb and 25.85% Zn or 2,481 g/t AgEq over 3 metres, extending the Rodilla Manto to the east. Hole 1108 successfully defined the post-mineral fault boundary separating and dislocating the Pierna-Rodilla Mantos by intersecting this fault and mineralization within it. This additional definition will allow for improved modeling and planning within this area. Both holes were inclined towards the known faulting in this important structural corridor to accurately model post-mineral structures displacing mineralization between these two mantos. EX16LP1110 was drilled into an area to the east of the 623 Manto extending known mineralization in this area.

Drilling from underground stations was successful in delineating additional new manto style mineralization, including hole EX16UG281 which intersected three discrete zones of mineralization grading; 686 g/t Ag, 4.69% Pb and 6.18% Zn or 1,193 g/t AgEq over 2.4 metres, 504 g/t Ag, 4.33% Pb and 7.08% Zn or 1,041 g/t AgEq over 2 metres and 843 g/t Ag, 0.41% Pb and 0.02%Zn or 861 g/t AqEq over 1.2 metres. This newly delineated mineralization was accessed in early 2017, with 1,107 tonnes extracted. More importantly these results further confirm the potential for new mineralization to be delineated in and around historical workings.

Exploration throughout 2017 will continue to focus on defining high-grade manto mineralization around the existing Platosa resources. Exploration will also continue to define structural controls within the resource that may lead to further discoveries of manto and feeder-style mineralization.

The Company also continues to develop its regional exploration program looking for CRD/Source-style mineralization, the most significant of which is the Rincon De Caido discovery, which encountered skarn-style mineralization in 2012/13, including 132 g/t Ag, 3.1% Zn, 1.7% Pb and 0.075 g/t Au over 55.5 metres in LP1019, 146 g/t Ag, 2.8% Pb. 1.9% Zn and 0.22 g/t Au over 43.4 metres in LP1023A and 13.1 g/t Au, 21 g/t Ag, 0.7% Pb and 3.6% Zn over 7.3 metres in LP 1038.

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 QAQC program, supervised by an independent Qualified Person.
