Excellon Announces High-Grade Assays and Further Expands Rodilla Manto Massive Sulphide Mineralization

TORONTO, ONTARIO--(Marketwire - Dec. 13, 2007) - Excellon Resources Inc. (TSX VENTURE:EXN) announces assays for five holes in the Rodilla Manto (first announced November 13, 2007; see table below) that include massive sulphide (LP411, 413, 419), sulphide breccia (LP417) and dispersed sulphide (LP421) intercepts. The massive sulphide intercepts range from 3.2 to 12.5 metres (m) in thickness and carry from 246 to 931 g/t (7.2 and 27.2 oz/T) silver; 7.2 to 8.2% lead; and 4.7 to 15.1% zinc. Sulphide breccia and dispersed sulphide intercepts are lower grade, reflecting varying carbonate wallrock content. These values are comparable to those previously reported from the Rodilla Manto (see press releases of November 13, 2007 and October 16, 2007) including the discovery hole (LP326), which cut 2.0 m (estimated true thickness) of massive sulphides grading 1,143 g/t (36.8 oz/T) silver with 8.3% lead and 10.7% zinc.

In addition, four new significant massive sulphide and sulphide breccia intercepts, ranging from 0.91 to 5.02 m thick (estimated true thickness) have been made in ongoing drilling of the Rodilla Manto (see table below). The massive sulphide intercepts in these four vertical holes consist largely of massive sphalerite with subordinate galena and 10 to 20% barite gangue. Assays for these holes, and several holes reported on November 13, 2007, are pending.

As now known, the Rodilla Manto is an irregularly-shaped, sub-horizontal massive sulphide lens approximately 70 m east-west by 90 m north-south in plan that remains open in several directions. The thickest portions of the Rodilla Manto mineralization lie around holes LP408 and LP413, which intersected 14.2 m and 12.5 m of high-grade massive sulphides respectively (see table below) and the manto is open beyond these holes. Rodilla is also open to the northeast where hole LP427A intersected 5.02 m of massive and brecciated sulphides, and to the west where hole LP432 cut 2.31 m of massive sulphides. Follow-up drilling is focused on enlarging the body in these directions.

Assay results are also reported for two previously announced sulphide breccia intercepts drilled off the southeastern edge of the Guadalupe Manto (LP387 and LP388).

"We are pleased to see the Rodilla Manto continue to the north and west and expect it to keep growing," said Richard W. Brissenden, Excellon's CEO and president. "We are also encouraged by advances in developing our targeting tools for exploring the overburden-covered areas extending outward from the Guadalupe and Rodilla Mantos. Our site geologists and our consulting geophysicist have begun integrating mapping and drilling information into a detailed interpretation of our airborne electromagnetic survey and initial indications are that structures and structural trends associated with the massive sulphide mantos can be detected geophysically. We expect to begin testing targets emerging from this effort early in the new year."

About Excellon

Excellon, a self-sustaining mineral resource company operating in Durango State, Mexico, is committed to building value through production, expansion and discovery. The Company is producing silver, lead and zinc from high grade manto deposits on its Platosa Property, strategically located in the middle of the Mexican silver belt. In fiscal 2008, Excellon's focus is on increasing its Mineral Resources through an aggressive $11-million exploration program, expanding its operation, and studying the feasibility of building a mill at site. The Platosa Property, not fully explored, has several geological indicators of a large mineralized system, the tracking of which Excellon believes will lead to the discovery of a world class deposit.
