Cigma Metals Corporation
1 Edith Place, Coolum Beach,
Queensland, Australia 4573

Gentlemen:

     We have acted as counsel to Cigma Metals Corporation, a Florida corporation
(the "COMPANY"), in connection with its registration statement on Form SB-2 (the
"REGISTRATION STATEMENT"), filed with the Securities and Exchange Commission
under the Securities Act of 1933 (the "ACT") on  August 18, 2006 for the
registration for resale by the selling stockholders listed therein (the "SELLING
STOCKHOLDERS") of 8,000,000 shares of the Company's common stock par value
$0.0001 per share (the "SHARES").

     All capitalized terms herein that are not otherwise defined shall have the
meaning ascribed thereto in the Registration Statement. In connection with this
opinion, we have examined and relied upon the Company's Articles of
Incorporation, as amended, the Company's Bylaws, Subscription Agreements
pursuant to which the Shares were acquired (the "TRANSACTION DOCUMENTS"), and
Registration Statement and related prospectus originals or copies certified or
otherwise identified to our satisfaction of all such corporate records of the
Company and such other instruments and other certificates of public officials,
officers and representatives of the Company and such other persons, and we have
made such investigations of law, as we have deemed appropriate as a basis for
the opinions expressed below. In addition, we have assumed truthfulness of the
representations, warranties and covenants of the Company and the Selling
Stockholders as set forth in the Transaction Documents and have not
independently verified the accuracy as to factual matters of each document
and/or instrument that we have reviewed.

     In arriving at the opinions expressed below, we have assumed the
authenticity of all documents submitted to us as originals and the conformity to
the originals of all documents submitted to us as copies.

     The opinions and other matters in this letter are qualified in their
entirety and subject to the following:

A. We have assumed that the Registration Statement and any amendments thereto
(including post-effective amendments) will have become effective and such
effectiveness shall not have been terminated or rescinded.



B. We express no opinion as to any constitutions, treaties, laws, rules or
regulations or judicial or administrative decisions of any jurisdiction ("LAWS")
other than (i) the federal Laws of the United States, (ii) the Business
Corporation Act of the State of Florida and (iii) the Laws of the State of New
York.

C. The matters expressed in this letter are subject to and qualified and limited
by (i) applicable bankruptcy, insolvency, fraudulent transfer and conveyance,
reorganization, moratorium and similar Laws affecting creditors' rights and
remedies generally; (ii) general principles of equity, including principles of
commercial reasonableness, good faith and fair dealing (regardless of whether
enforcement is sought in a proceeding at law or in equity); (iii) commercial
reasonableness and unconscionability and an implied covenant of good faith and
fair dealing; (iv) the power of the courts to award damages in lieu of equitable
remedies; and (v) securities Laws and public policy underlying such Laws with
respect to rights to indemnification and contribution.

     Based upon and subject to the foregoing, we are of the opinion that the
Shares have been validly issued and are fully paid and non-assessable.

     This opinion is given as of the date hereof and we assume no obligation to
update or supplement such opinion to reflect any facts or circumstances that may
hereafter come to our attention or any changes that may hereafter occur.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to this firm under the heading
"LEGAL MATTERS" in the Registration Statement and the related prospectus
included in the Registration Statement. In giving such consent, we do not
thereby admit that we are "experts" within the meaning of the Act or the rules
and regulations of the Commission issued thereunder with respect to any part of
the Registration Statement, including this opinion which is annexed thereto as
an exhibit.


Very truly yours,

Sierchio Greco & Greco, LLP
