Excellon Resumes Drilling at La Platosa

TORONTO, ON--(Marketwired - August 17, 2016) - Excellon Resources Inc. (TSX: EXN) (TSX: EXN.WT) (OTC: EXLLF) ("Excellon" or the "Company"), Mexico's highest grade silver producer, is pleased to announce that it has commenced an initial 25,000 metre diamond drilling exploration at its 100%-owned La Platosa property in Durango, Mexico, where the Company has been mining since 2005.

Outlook for Platosa Drill Program

• Initial focus on massive sulphide targets near existing mine infrastructure that may be accessed by operations with minimal development (estimated 6,000 metres of drilling)
  
• Subsequent focus on near-surface massive sulphide targets near the Platosa mine with the aim of discovering new manto deposits near Platosa (estimated 13,000 metres)
  
• Ongoing exploration and drilling of carbonate replacement deposit ("CRD") "Source" targets (estimated 6,000 metres)
  
• Cutting-edge analysis of historical geophysical data by Geotech Ltd. ("Geotech") under way and expected to identify previously invisible, regional CRD/Source targets

"We are incredibly excited to be back exploring Platosa again," stated John Sullivan, Vice President Exploration. "We have conducted minimal drilling to expand Platosa manto resources since 2011, and the area near the Platosa mine itself remains wide open for the discovery of new mantos both laterally and at depth. Additionally, we are revisiting the geophysical data collected at Platosa from 2006 to 2011 with the help of Geotech. With today's much faster processing power, along with the cutting edge application of neural networking and artificial intelligence, we hope to obtain an entirely new perspective on exploration at Platosa. We remain convinced that the Platosa mantos are merely the edge of a much larger CRD system."

The Platosa Mine exploits a series of very high-grade, closely-spaced, CRD silver, lead, zinc manto deposits located within the prolific Mexican CRD belt. CRDs are intrusive-related, sulphide-dominant lead, zinc, silver, copper, often gold-rich deposits that commonly occur in clusters associated with major regional geologic features. The Mexican CRD Belt is perhaps the world's best-developed CRD cluster and Platosa lies in the centre of the northwest-southeast-trending axis of the largest deposits of the belt.
