Previous drilling at Rincon del Caido, which is located 1.1 km northwest of the La Platosa mine, encountered "Source"-type geology and sulfide mineralization.

Excellon Resources vice-president Exploration John Sullivan, said, "Our most recent drilling results provide the clearest evidence to date that we are in a Source environment and nearing the large-tonnage CRD Source that has been the ultimate object of our exploration at La Platosa."

He added that a third drill will be mobilized by the end of September as part of the company’s plan to follow-up the Rincon del Caido drilling results in 2012.

The mining company plans to undertake downhole geophysical surveying to guide additional drilling, given the volume of mineralization.

The La Platosa mine was earlier blocked by a few worker unions and environmental groups. The company has regained access to the mine on August 30, 2012, when the workers entered the area through an alternative access.

Excellon plans to recommence full production at the La Platosa mine after obtaining re-opening permits.
