Toronto, Ontario – June 25, 2014 – Excellon Resources Inc. (TSX:EXN; OTC:EXLLF) ("Excellon" or the “Company"), Mexico’s highest grade silver producer, is pleased to report the resumption of diamond drilling at its 100%-owned La Platosa Mine located in Durango State, Mexico. Highlights of the ongoing exploration program include:

• 10,000 metre diamond drilling program underway, focused on discovering new high grade, massive sulphide mantos near current mining operations and following up on the carbonate replacement deposit (“CRD”) “source”-style discovery announced in 2012.
• 2D seismic test survey to be completed early in the third quarter in advance of a comprehensive 3D seismic survey to be commenced during the third quarter.

"We are excited to resume drilling at La Platosa,” stated John Sullivan, Vice President Exploration. “During the past year, we have re-examined the data generated during our recent drilling programs, particularly in respect of the Source-style discovery made in 2012. We will also shortly be commencing a seismic survey near current mining infrastructure which, if successful in direct detection of massive sulphides, may be a cost-effective way of discovering new high grade mantos."

Seismic surveying has recently become cost-competitive with more conventional geophysical methods and has played a key role in recent massive sulphide discoveries by Canadian companies in Spain and northern Manitoba. Seismic surveying uses acoustic waves to measure the characteristics of responses reflected back to surface from the rock units and structures encountered. The significant sound speed and density differences between massive sulphide manto mineralization and the sub-horizontal limestone unit in which it is hosted are expected to provide an ideal environment for successful seismic study. This method has the potential to significantly reduce exploration costs and expedite discovery by enhancing the Company’s understanding of sub-surface geology and outlining direct drilling targets.

The Company has engaged Olson Engineering, Inc. of Wheat Ridge, Colorado to undertake the initial 2D seismic reflection test survey over the high-grade Pierna and NE-1 mantos (Figure 1). Assuming successful identification of these known mantos, the Company intends to carry out 3D seismic surveys over underexplored areas elsewhere on the property.

A 10,000 metre diamond drill program has also been approved for the remainder of the year and commenced last week. Drilling will focus on (i) manto targets developed by the seismic survey and otherwise by Company geologists during recent months, and (ii) on the Rincon del Caido discovery made in 2012, one kilometre northwest of the La Platosa Mine (Figure 2). Significant potential remains for further new manto discoveries as the deposit is open to the north, northeast, east and southeast of the known mantos.

The Company believes that the Rincon discovery is on the edge of the Source of the Platosa carbonate replacement deposit system and may also be related to the Platosa mantos. To date, Excellon has drilled 13 significant intersections in the Rincon-Mantos corridor northwest of the La Platosa Mine, including:
