Earth Search Sciences Announces Development of New Marketing Program for Hyperspectral Data Packages Over Key Mineral and Oil & Gas Regions

KALISPELL, MT -- (MARKET WIRE) -- April 28, 2005 -- Earth Search Sciences, Inc. (OTC BB: ESSE), a proven supplier of reliable data in the exploration for new mineral discoveries by airborne hyperspectral remote sensing announces the development of a new, industry-standard setting, marketing program featuring packaged data covering key development regions of the world.

Earth Search's hyperspectral scientist, Dr. Joe Zamudio, said, "The hyperspectral remote sensing industry has been a custom order, custom flight, custom data collection business since its beginning. This has made it expensive and time consuming for customers. Earth Search now has enough data in its archive from key exploration regions in the world to begin packaging it differently. Customers will be able to buy the end results, a completed map of hyperspectral imagery over an area of minerals or hydrocarbons that is a hot exploration region, in the size they want."

The Earth Search data archive covers over 200,000 sq. km. from 4 continents. Existing remote sensing technology provides the ability to identify objects primarily by shape or a general spectral response. However, Earth Search Science's revolutionary hyperspectral imaging can measure a fine degree of spectral reflectance of solar energy from across the spectrum and allow the user to identify specific minerals and substances on the surface of the earth by their diagnostic reflectance patterns.

The new ESSI website at http://www.earthsearch.com features detailed presentations by CNN's Lou Dobbs and the National Geographic Explorer on the history of the Company's first exploration ventures.
