Induced Polarization Survey Begins on Delta Mining and Exploration's Delcer Buttes Gold/Copper Property

LEWISBURG, KY -- (MARKET WIRE) -- 05/19/10 -- Delta Mining & Exploration (PINKSHEETS: DMXC) ("Delta") is pleased to announce that Gradient Geophysics has commenced the 2nd round of exploration work on the Delcer Buttes Property, in Elko County, Nevada.

After successful completion of the magnetometer survey this past month in which several anomalies were indentified, including a magnetite rich zone approximately 1 kilometer in length trending towards the west in the northern portion of the property, Gradient Geophysics has started collecting additional data on Delcer Buttes through an Induced Polarization ("IP") survey.

The IP will provide a method in testing for sulfide mineralization -- often associated with mineralized skarn. Areas of pyrite, chalcopyrite, bornite, and pyrrhotite -- sulfides often associated with gold and copper mineralization -- will be delineated using the IP method.

In addition, the resistivity part of IP will provide a mapping tool for the project area for determining rock units and faults as well as a 3-Dimensional sampling tool, on a large scale, for detailed mineral exploration. The combined results of the magnetometer and IP surveys will be followed up on the ground by mapping and sampling. The survey should take roughly a month to complete, and once the results are known they will be made public.

Delta Mining & Exploration, www.deltamine.com, is an emerging exploration company locating mineral and precious metal deposits in the mining rich regions of North America. The Company currently owns mineral rights to land in central Montana as well as the rights to 31 claims on 680 acres in Elko County, Nevada.
