Cayden Resources Inc. is pleased to announce that it has received initial results from drilling at the Las Calles target at the Morelos Sur Gold project. The Company has also received its first trench results from the La Magnetita target, as well as additional trench results from the La Joya target. The drilling highlight at Las Calles includes 14 meters of 4.2 g/t Au (LCDD0093), which occurs in an extremely fractured and iron oxide-rich diorite sill. Additional drill holes have been completed and are awaiting assay. The initial results indicate the potential for a deeper, lateral extension of the ore body currently being mined by Desarrollos Mineros San Luis (DMSL), a subsidiary of Goldcorp, at the Los Filos mine. Drill hole locations are shown at www.caydenresources.com . Cayden is continuing its Las Calles drilling with the two existing drills. The Company is also adding another core drill and a reverse circulation (RC) drill to perform some pre-collar drilling in some areas of particularly broken ground.
