Dear Sirs:

Re:  Common Stock of Ameriwest Minerals Corp. Registered on Form S-1, filed on
     October 14, 2008

We have  acted as  counsel  to  Ameriwest  Minerals  Corp.  (the  "Company"),  a
corporation  incorporated  under the laws of the State of Nevada,  in connection
with the filing,  on October 14, 2008, of a  registration  statement on Form S-1
(the "Registration Statement") under the SECURITIES ACT OF 1933, as amended (the
"Securities  Act") of  3,250,000  shares  of the  Company's  common  stock  (the
"Registered  Shares") for resale by certain  selling  shareholders  named in the
Registration Statement.

We have examined the originals or certified copies of such corporate  records of
the Company and/or public  officials and such other documents and have made such
other factual and legal  investigations as we have deemed relevant and necessary
as the basis for the  opinions  set forth  below.  In our  examination,  we have
assumed the  genuineness of all  signatures,  the  authenticity of all documents
submitted to us as originals, and the conformity to authentic original documents
of all  documents  submitted  to us as  copies  or as  facsimiles  of  copies or
originals, which assumptions we have not independently verified.

Based upon the foregoing and the  examination  of such legal  authorities  as we
have deemed relevant,  and subject to the qualifications and further assumptions
set forth below, we are of the opinion that the Registered  Shares were duly and
validly authorized and issued, fully paid and non-assessable.

We have made such  inquiries  with respect  thereto as we consider  necessary to
render this opinion with respect to a Nevada corporation. This opinion letter is
opining  upon and is limited to the current  federal  laws of the United  States
and, as set forth above,  Nevada law,  including the statutory  provisions,  all
applicable provisions of the Nevada Constitution and reported judicial decisions
interpreting  those laws, as such laws presently  exist and to the facts as they
presently   exist.  We  express  no  opinion  with  respect  to  the  effect  or
applicability of the laws of any other jurisdiction.  We assume no obligation to
revise or supplement this opinion letter should the laws of such jurisdiction be
changed  after the date  hereof by  legislative  action,  judicial  decision  or
otherwise.

We  hereby  consent  to  the  filing  of  this  opinion  as an  exhibit  to  the
Registration  Statement.  In giving  this  consent,  we do not admit that we are
within the category of persons whose consent is required  under Section 7 of the
Securities  Act of 1933 or the General Rules and  Regulations  of the Securities
and Exchange Commission.

                                      Yours truly,


                                      /s/ W.L. MACDONALD LAW CORPORATION
