            to Registration Statement on Form SB-2 (Registration No. 333-101055)

Ladies and Gentlemen:

         Pursuant to Rule 477 under the  Securities Act of 1933, as amended (the
"Act"), HiEnergy Technologies,  Inc., a Delaware corporation (the "Registrant"),
hereby  requests  your  consent  that  the  above  captioned  amendments  of our
Registration  Statement  be  withdrawn  as of the date of filing  hereof.  These
amendments have not yet been declared effective.

         The  Registrant  has determined  that the  Registrant's  best interests
would be  served at this  time by  withdrawing  such  amendments  to  facilitate
changes to the structure of the primary  offering to reflect  developing  market
conditions and financing opportunities.

         The  Registrant  believes  you will agree that  these  withdrawals  are
consistent  with the  public  interest  and the  protection  of  investors.  The
Registrant  represents  that no securities have been offered or sold pursuant to
these amendments to our Registration Statement.

         If you have any  questions  or  comments,  please  do not  hesitate  to
contact our legal  counsel,  Nicholas  J. Yocca of Yocca  Patch & Yocca,  LLP at
(949) 798-0190.

         Thank you for your  attention  to this matter and your  assistance  and
cooperation throughout the registration process.


                                  Very truly yours,

                                  HIENERGY TECHNOLOGIES, INC.
