Company engages experienced Colorado engineering firm for turnkey

   development of the field-test and a full scale prototype, designed to

                 recover oil shale, tar sands and heavy oil



    LAKESIDE, Mont., July 28 /EMWNews/ -- Earth Search

Sciences, Inc., (OTC Bulletin Board: ESSE) has engaged Industrial Systems,

Inc. (ISI) of Delta, Colorado, to design, fabricate and install the

components for a full-scale test of its patented technology to recover

hydrocarbons through an environmentally low impact gasification process.



    "ISI brings to the table a great team of professionals who have

demonstrated experience across the spectrum of oil, gas, chemicals, and

mining industries," said Luis F. Lugo, CEO of Earth Search. "We are

confident their turnkey capabilities will enable a successful test of our

ground-breaking technology to develop domestic energy resources."



    Lugo said ISI will be responsible for engineering a full-scale test and

commercial prototype for key Earth Search Sciences subsidiary, Petro Probe,

Inc., expected to start production within the next few months.



    "We have been involved with oil shale since the 1980s and have seen a

number of technologies come and go," said Bob Isom, President of ISI. "We

are optimistic this innovative technology represents a significant leap

forward and are extremely pleased to be designing a system that will prove

the technology's feasibility in the field."



    Lugo said moving forward with the field test will provide engineering

and production data to establish the basic economics that will drive the

success of this technology on a commercial scale.



    "Our timing could not be better," said Lugo. "All variables favor our

project and we expect to yield positive results in a matter of months, not

years."

    About Earth Search Sciences -- http://www.earthsearch.com



    Earth Search Sciences, Inc.'s [OTCBB:ESSE] revolutionary hyperspectral

technology provides the ability to accurately read the chemical properties

of surface substances from great altitudes and produce easily interpreted

maps allowing the user to identify specific minerals and substances on the

surface of the earth by their diagnostic reflectance patterns. Ultimately,

this remote sensing capability identifies a greater number of exploration

targets quickly and economically, monitors the environmental situation, and

improves the probability of finding anomalies. Older, more conventional

methods would take decades to cover the same area, and at a much greater

cost. Within the realm of exploration, remote sensing does not replace the

need for geological knowledge, geochemistry, geophysics, seismic, drilling,

etc, which are some of the more conventional tools used for exploration.

The application of Earth Search's patented and IP-protected hyperspectral

technology cuts across the commercial, medical and military spectra.



    About Petro Probe -- http://www.petroprobe.com



    Petro Probe, Inc. is a private petroleum company using advanced

technology in the search for and production of hydrocarbon products. The

company was formed in 2000 as a majority-owned subsidiary of Earth Search

Sciences, Inc. (http://www.earthsearch.com), a public company listed on the

OTCBB exchange under OTCBB:ESSE. Petro Probe's mandate is to identify and

develop hydrocarbon properties utilizing Earth Search Science's exploration

programs, including the use of a new patented method to recover oil and gas

within oil shale, tar sands and heavy oil that positions the company to

become a significant presence in the oil shale and heavy oil industry. The

company has established a clear path to grow and develop Earth Search

Sciences and Petro Probe in the oil shale, tar sands and heavy crude market

segments.
