Re: Legal Opinion Pursuant to SEC Form S-1
    Registration Statement - Mesquite Mining, Inc.

Dear Ms. Frederick:

You have requested my opinion as special counsel for Mesquite Mining, Inc., a
Delaware corporation (the "Company") for the limited purpose of rendering this
opinion in connection with the Company's Registration Statement on Form S-1 and
the Prospectus included therein (collectively the "Registration Statement")
relating to a proposed offering by the Company to the public of 1,000,000 shares
of the Company's Common Stock, $0.0001 par value (the "Shares"), to be filed
with the Securities and Exchange Commission.

The following opinion is based upon the Securities Act of 1933 as amended (the
"Act") and Delaware securities laws, including without limitation, the statutory
provisions, all applicable provisions of the Delaware constitution and reported
judicial decisions interpreting those laws.

The Shares are to be offered by the Company in a best efforts, direct public
offering without any involvement of underwriters, as described in the
Registration Statement. We have examined originals or copies, certified or
otherwise identified to our satisfaction, of such corporate records,
certificates and written and oral statements of officers and accountants of the
Company and of public officials, and other documents that we have considered
necessary and appropriate for this opinion.

Upon the basis of the foregoing, we are of the opinion that the Shares, when
sold pursuant to and in accordance with the Registration Statement and the
documents described therein, will be validly issued, fully paid and
nonassessable.
