Sundance to Commence Drilling at the Pluton Property in Mapimi, Durango, Mexico

TORONTO, ONTARIO -- (Marketwire) -- 07/25/11 -- Project operator Sundance Minerals Ltd. ('Sundance') and Excellon Resources Inc. ('Excellon') (TSX: EXN) are pleased to announce that they have agreed to commence drilling at the Pluton property in Mapimi, Durango, Mexico. The program consists of a first stage of 3,500 m of diamond drilling to partially-test four out of five targets identified to date in the property. Drilling will be carried by Major Drilling of Hermosillo, Mexico under the supervision of Sundance geologists.

The program will be conducted under the terms of the option agreement between Excellon's Mexican subsidiary Minera Excellon de Mexico, S.A. de C.V. and Sundance's Mexican subsidiary, Minera Teocuitla S.A de C.V., which was effective on October 22, 2010. Excellon may earn a 60% initial interest in the property by incurring C$1,500,000 in exploration expenditures over three years, C$500,000 of which are a firm commitment expected to be completed during the current drilling campaign. Sundance is the project operator during this initial earn-in phase of the agreement. Excellon may earn an additional 15% interest for a total of 75% by completing a pre-feasibility study within another three years.

Sundance controls 100% of the Pluton Property, an extensive 17,000 ha claim block located 20 km west Excellon's Platosa Mine and contiguous with Excellon's Platosa exploration property. The Pluton property contains five large carbonate replacement ('CRD') type targets, two to four kilometres long each, that have been identified and verified with multiple geological, geochemical and geophysical datasets.

The Pluton Property covers the western portion of a large regional magnetic feature that is believed to reflect underlying intrusives favourable to the development of CRD systems. The Platosa Mine is located on the eastern side of the same regional feature and the past producing Ojuela Mine (6 million tonnes of high-grade Ag, Au, Pb, Zn production from a series of CRD chimneys and mantos) sits on the south-central side. The Pluton Property covers favourable geology with sulphide showings and other signs of proximity to a mineralizing source along the extensive (over 15 kilometres) western portion of the above mentioned magnetic feature.

The objective of this campaign is to ground truth geophysical and geochemical anomalies. Specific objectives include obtaining stratigraphic, structural and alteration information at depth, as well as probing vein structures and their connection with carbonate replacement mineralization at depth. This information will provide feedback for further classification and interpretation of ZTEM airborne electromagnetic survey data collected over a portion of the property during the course of a larger survey flown by Excellon in the fall of 2010. Subsequently these data sets will be combined and analyzed with the ultimate goal of developing additional drilling targets, which the companies believe may lead to the discovery of a CRD deposit on the Pluton Property.
