TORONTO, ONTARIO--(Marketwire - Aug. 16, 2010) - Excellon Resources Inc. (TSX:EXN) (the "Company" or "Excellon") reports earnings after tax of $464,197 for the three months ended June 30, 2010. In December 2009 the Company changed its year end to December 31 from July 31.

                                                                           
Period End Highlights:                                                      

--  The Company again reports profits with good operating performance at
    Platosa. Profitability continues to be enhanced by the operation of the
    Miguel Auza Mill acquired in June 2009. 
--  In the quarter the Company shipped 352,814 oz. of payable silver,
    1,729,004 lbs of payable lead and 2,403,364 lbs of payable zinc (on a
    provisional basis). 
--  Net cash costs after lead and zinc by-product credits for the three
    months ended June 30, 2010 were US$5.82. 
--  Exploration expenses for the quarter totalled $3,265,676 for the on-
    going programs at Platosa and Miguel Auza. Results at Platosa continue
    be successful and encouraging. 
--  Cash at June 30, 2010 was $4.9million. Aggressive exploration spending,
    equipment purchases and timing of sales shipments have led to the
    decrease in the second quarter. 

"Platosa continues to provide consistent and profitable operating performance for Excellon as evidenced by these results for the quarter ended June 30, 2010." commented Peter Crossgrove, Excellon's Chief Executive Officer. "The second quarter was weaker than the first quarter due to mining lower grades as the higher grade Guadalupe South manto was inaccessible due to the installation of water control systems. In addition, mining crews were partially focused on developing additional mining areas with the arrival of new mining equipment on site. Mining operations in the month of June returned to budgeted levels. While the quarter provided slightly lower volumes than recent history, the Company remained profitable even with aggressive exploration expenses that reduced earnings by approximately $1 million per month. This successful drilling program is producing continued manto mineralization additions and increasing evidence for the discovery of the proximal source."

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 fiscal 2010, Excellon's focus is on expanding its operating capacity and increasing its Mineral Resources at Platosa through a CDN$12 million exploration program where five 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 was completed in June.
