                                  NEWS RELEASE
                             FOR IMMEDIATE RELEASE

                         HIENERGY TECHNOLOGIES ANNOUNCES
                  TERMINATION OF INVESTIGATION BY S.E.C. STAFF

IRVINE, Calif., Sept. 2 HiEnergy  Technologies,  Inc. (OTC Bulletin Board: HIET)
(the "Company" or "HiEnergy")  announced today that it was notified by the staff
of the  Securities  and Exchange  Commission  that the formal  investigation  of
HiEnergy has been terminated with no enforcement  action. The staff said that it
has completed its investigation  and no enforcement  action has been recommended
to the Commission at this time.

As  previously  disclosed  by  HiEnergy,  the  Commission  authorized  a  formal
investigation and delivered a Wells Notice to the Company in June 2004, advising
it of the staff's intention to recommend enforcement action against the Company.
During  the  course  of the  investigation,  HiEnergy  has  cooperated  with the
Commission and its staff.

"We are pleased that the S.E.C staff  decided not to recommend  any  enforcement
action against  HiEnergy," said Dr. Bogdan C. Maglich,  HiEnergy's  Chairman and
CEO. "We appreciate the  opportunity  which the Commission  gave us to cooperate
with its investigation,  and we would like to thank those who have been involved
for their diligent effort."

ABOUT HIENERGY TECHNOLOGIES, INC.

HiEnergy  Technologies,  Inc. ("HiEnergy",  together with its subsidiaries,  the
"Company") is a nuclear  particle  detection  technology  company focused on the
commercialization  of the world's first  "stoichiometric"  explosive  diagnostic
devices,  including (i) the CarBomb Finder(TM) 3C4, a vehicle-borne  system, for
the detection and  identification  of car bombs,  and (ii) the SIEGMA(TM) 3E3, a
portable suitcase-borne system for the detection and identification of home-made
bombs,  also  known as  Improvised  Explosive  Devices or IEDs.  The  Company is
marketing its devices to  governmental  and private  entities and is negotiating
licenses for distribution of its devices with various industry partners.




The  Company  also  continues  to  focus  on the  research  and  development  of
additional applications of its technologies and their further exploitation, both
internally and through  collaboration with third parties.  HiEnergy is currently
developing  prototypes in programs  with the U.S.  Department of Defense and the
Department of Homeland  Security for other related uses of its core  technology.
Recently,  it entered into a funded cooperative  development  agreement with the
U.S.  Transportation Security Administration (TSA) to produce a proof of concept
which  incorporates  the  Company's  SuperSenzor(TM)  technology  into a baggage
screening system. The Company's "stoichiometric" technology, or Stoitech(TM) has
been incorporated into additional  prototype  applications which, if the Company
is able to raise the funds  necessary to  commercialize  them,  will be the next
products it attempts to launch: (i) an in-ground explosive screening system, the
CarBomb Finder(TM) 3C5, (ii) an anti-tank landmine detector; (iii) an unexploded
ordnance  detector,  which is also useful to detect IEDs;  and (iv) a device the
Company calls a "Refractorymeter,"  which can detect fissures or erosions in the
ceramic lining of oil cracking tanks.
