Mexoro Minerals Adds Second Drill Rig to Its Cieneguita Project in Mexico

CHIHUAHUA, Mexico, Aug. 18 /PRNewswire-FirstCall/ -- Mexoro Minerals Ltd. Adds Second Drill Rig To Its Cieneguita Project. (BULLETIN BOARD: MXOM) (Frankfurt: OYA1).

Mexoro Minerals Ltd. is pleased to announce that it is adding a second drill rig to its Cieneguita Project located in Chihuahua, Mexico. The current drill rig is now drilling to the west of the known limits of the mineralized zone and is finding significant intersection of mineralized rock similar to drill holes CI-29 CI-30 CI-34 and CI-35. Assay results are pending on these recent drill holes drilled outside the known limits of mineralization. The second drill rig will begin infill drilling on 40 meter spacing so that a resource estimate compliant to NI 43-101 can be made as soon as possible.

Barry Quiroz, VP Exploration states, "Current drilling seems to indicate that the center of the mineralized system is in the area of CI-30, CI-34 and CI-35. Recent drilling suggests that the flow of fluids was from this center of the system to the east ending near Pit 1. The new drill holes to the west appear to be finding that there was also a flow of fluids that were depositing mineralization in the westerly direction. Recent drilling on 80 meter spacing has not defined the western edge of the known mineralization yet, which implies that the mineralized zone may be much larger than first anticipated."

These results have been prepared under the supervision of Barry Quiroz, MSc., Mexoro VP of Exploration. He has the expertise and authority to verify the authenticity and validity of this data. The qualified person who has reviewed this news release is Dana C. Durgin, MSc., Economic Geology.
