Luis Castro, Vice President of Exploration, commented, "We are encouraged that our exploration drilling continues to find new zones of high grade mineralization at relatively shallow depths within historic veins on the Bolanitos property. The Gabriela mineralization sits adjacent to historic mine workings that should provide easy access for future mining if a large enough block of mineral can be outlined."

Godfrey Walton, M.Sc., P.Geo., Endeavour's President and COO, is the Qualified Person who reviewed and approved this news release and supervised the drilling programs in Mexico.
