RE:  INTREPID TECHNOLOGY & RESOURCES, INC. (THE "CORPORATION")
REGISTRATION STATEMENT ON FORM S-8 (THE "REGISTRATION STATEMENT")

Gentlemen:

I  have  acted  as  special  counsel  to  the Corporation in connection with the
preparation of the Registration Statement filed with the Securities and Exchange
Commission  pursuant to the Securities Act of 1933, as amended (the "1933 ACT"),
relating  to  the  proposed  public  offering  of  up  to  1,000,000 shares (the
"SHARES")  of  the  Corporation's  common stock, par value $0.005 per share (the
"COMMON  STOCK").

I  am  furnishing  this  opinion  to  you  in  accordance with Item 601(b)(5) of
Regulation  S-K  promulgated under the 1933 Act for filing as Exhibit 5.1 to the
Registration  Statement.

I  have  reviewed  the  Registration  Statement,  and  I  have  examined  the
Corporation's  Certificate  of  Incorporation,  as  amended  to  date,  the
Corporation's  Bylaws,  as  amended  to date, and minutes and resolutions of the
Corporation's  Board  of  Directors  relating  to  the registration and proposed
issuance of the Shares. I have also examined such other documents, certificates,
instruments and corporate records, and such statutes, decisions and questions of
law as I have deemed necessary or appropriate for the purpose of this opinion.

Based  upon  and  subject to the foregoing, it is my opinion that the Shares are
duly  authorized  for  issuance  by the Company and, when issued and paid for as
described  in  the Company's 2005 Stock Incentive Plan incorporated by reference
in  the  Registration  Statement,  will  be  validly  issued,  fully  paid,  and
nonassessable.  It  is also my opinion that any Shares issued to persons who are
not  "affiliates" of the Company as defined in Rule 144 ("RULE 144") promulgated
under  the  1933  Act  may  be  issued  without transfer restrictions or legends
because  the  Shares  are not "restricted securities" within the meaning of Rule
144.  Any  Shares  issued  to  "affiliates" of the Company may be resold only in
accordance  with  Rule 144 and therefore the certificates evidencing such Shares
should  bear  appropriate  restrictive  legends.

I hereby consent to the filing of this opinion as an Exhibit to the Registration
Statement  and  to  the  use  of  my  name in the Prospectus constituting a part
thereof  in  connection  with  the  matters referred to under the caption "Legal
Matters."

Very  truly  yours,


  /s/  Michael  J.  McDonagh
