“Platosa continues to provide consistent and profitable operating performance for Excellon as evidenced by these results for the quarter ended March 31, 2010.” commented Chris Hopkins, Excellon’s Chief Financial Officer. “Profits and a growing cash position in the quarter were achieved in spite of slightly lower silver prices and an aggressive drilling program in the quarter. Given these steady ongoing results we continue to remain confident that 2010 will produce record production volumes and revenues in line with previous guidance.”

About Excellon

Excellon, a mineral resource company operating in Durango and Zacatecas States, Mexico, is committed to building value through production, expansion and discovery. Excellon is producing silver, lead and zinc from the high-grade manto Mineral Resource on its large Platosa Property, strategically located in the middle of the Mexican silver belt. In 2010, Excellon's focus is on expanding its operating capacity and increasing its Mineral Resources at Platosa through a CDN$11 million exploration program where four diamond drills are in operation. The Platosa Property, not fully explored, has several geological indicators of a large mineralized system. The equally large Miguel Auza property hosts an Indicated and Inferred Mineral Resource and was the site of considerable historic mining for silver,(gold), lead and zinc. The exploration potential of Miguel Auza remains to be fully evaluated and is the object of an ongoing exploration program, which began in the fall of 2009. A one-drill initial target testing program began there in early April.
