Excellon Reports Second Quarter 2015 Production

TORONTO, ON--(Marketwired - July 21, 2015) - Excellon Resources Inc. (TSX: EXN) (OTC: EXLLF) ("Excellon" or the "Company"), Mexico's highest grade silver producer, is pleased to announce second quarter 2015 production results from the La Platosa Mine in Durango, Mexico.

Q2 2015 Production Highlights (Compared to Q2 2014)

• Silver equivalent ("AgEq") production of 341,975 oz (Q2 2014 - 636,713 AgEq oz)
• Silver production of 182,709 oz (Q2 2014 - 374,266 oz)
• Lead production of 1.0 million lb (Q2 2014 - 2.3 million lb)
• Zinc production of 1.7 million lb (Q2 2014 - 3.1 million lb)

"Production remains on track to meet guidance for the year, with grade and tonnage during the quarter generally in line with the mine plan for the period," stated Brendan Cahill, President and Chief Executive Officer. "We remain focused on the optimization project for Platosa and existing pump infrastructure is already being upgraded. The second phase of the program is expected to commence prior to the fall and will initially focus on preparatory test work in advance of drilling dewatering wells and underground drain wells."

Ore production during the second quarter was primarily from the 6A, Guadalupe South, Guadalupe North and periphery of the 623 mantos, with development focused on the 6A, 623 and access to the Rodilla mantos. Grades during the quarter, though lower than in previous periods, were in line with estimates for the Platosa mineral resources mined during the period and the Company’s current mine plans.

Recoveries were impacted by the relatively lower grades of ore processed, but are expected to return to normal levels as higher grade ore is accessed. During the period, water management at Platosa was effective at controlling inflows, though continues to limit productivity and development in operations as expected. As announced on June 2, 2015, the Company has developed an optimization program to comprehensively manage water at Platosa in the future through an enhanced pumping system, the implementation of which is in early stages. Further updates on this program will be provided through the remainder of the year.

The Company is currently accessing the periphery of the high-grade 623 Manto, hosting mineral resources of 83,000 tonnes at 1,231 g/t Ag (1,766 g/t AgEq), with this manto expected to reach full production during the second half of 2015 as access ramps reaches the main body of that manto.

The Company expects to release second quarter financial results prior to market open on August 13, 2015.
