         Re:      8,264,500 Shares Common Stock $0.001 Par Value
                  Form SB-2 Registration Statement

Ladies and Gentlemen:

I have acted as counsel for Pioneer  Exploration Inc., a Nevada corporation (the
"Company"),  in connection with the preparation of the registration statement on
Form SB-2 (the  "Registration  Statement")  to be filed with the  Securities and
Exchange  Commission (the "Commission")  pursuant to the Securities Act of 1933,
as amended  (the "Act"),  relating to the  offering of  8,264,500  shares of the
Companys common stock.

In rendering the opinion set forth below, I have reviewed:  (a) the Registration
Statement  and the exhibits  attached  thereto;  (b) the  Company's  Articles of
Incorporation;  (c) the Company's  Bylaws;  (d) certain records of the Company's
corporate  proceedings as reflected in its minute books;  and (e) such statutes,
records and other documents as I have deemed relevant. In my examination, I have
assumed the  genuineness of all  signatures,  the  authenticity of all documents
submitted to me as originals, and conformity with the originals of all documents
submitted  to me as  copies  thereof.  In  addition,  I  have  made  such  other
examinations of law and fact, as I have deemed relevant in order to form a basis
for the opinion hereinafter expressed.

Based upon the  foregoing,  I am of the  opinion  that the  8,264,500  shares of
common stock to be sold by the selling  shareholders  is validly  issued,  fully
paid and non-assessable. This opinion is based on Nevada general corporate law.

I hereby  consent to the use of this  opinion as an exhibit to the  Registration
Statement and to all references to this firm under the caption  "Experts" in the
Registration Statement.

Sincerely,

/s/  Gary R. Henrie
