Our opinion is confined to, and given on the basis of, the laws of England and Wales as applied by the courts of England and Wales at the date of this opinion letter and we have made no investigation of the laws of any country or jurisdiction other than England and Wales. We do not assume any obligation to provide you with any subsequent opinion or advice by reason of any fact about which we did not have knowledge at the time of issuance of this opinion, by reason of any change subsequent to that time in any law, or for any other reason. Furthermore we do not express any opinion on European Union law as it affects any jurisdiction other than England and Wales (and, for this purpose, we have assumed that all statutory instruments and/or regulations made in England and Wales in purported implementation of any directive have been duly made in accordance with that directive and are valid in all respects under the laws of England and Wales). The opinions given in this opinion letter are strictly limited to the matters stated in paragraph 4 (Opinions) below and do not extend to and are not to be read as extending by implication to any other matters in connection with the resolutions contained in the Board Resolutions. We express no opinion as to matters of fact.

This opinion letter and all non-contractual obligations arising out of or in connection with it shall be governed by and construed in accordance with the laws of England and Wales as at the date of this opinion letter.

OPINIONS

Based upon and subject to the foregoing and subject to the reservations, qualifications and observations set out in paragraph 5 (Qualifications) below and to any matters not disclosed to us, we are of the opinion that:

4.1	Tronox is a public limited liability company duly incorporated and validly existing under the laws of England and Wales; and

4.2	the Shares will be validly issued, fully paid and non-assessable. For the purposes of this opinion, “non-assessable” shall mean that no further contributions in respect of the Shares will be required to be made to Tronox by the holders thereof by reason solely of being a holder of such Shares.

5.	QUALIFICATIONS

The opinions expressed in this opinion letter are subject to the following reservations, qualifications and observations:

5.1

the Records Search is not conclusively capable of revealing whether or not (i) a winding-up order has been made in respect of a company or a resolution passed for the winding up of a company, or (ii) an administration order has been made in respect of a company, or (iii) a receiver, administrative receiver, administrator or liquidator has been appointed in respect of a company, since notice of these matters might not be filed with Companies House immediately and, when filed, might not be made available through the website or entered on the files of Companies House relating to insolvency details with respect to the relevant company immediately. In addition, such searches are not capable of revealing, prior to the making of the relevant order, whether or not a winding-up petition or a petition for an administration order has been presented; and

5.2

the Central Index Search relates only to a compulsory winding up and is not capable of revealing conclusively whether or not a winding-up petition in respect of a compulsory winding up has been presented since details of the petition may not have been entered on the records of the Central Index of Winding‑Up Petitions immediately or, in the case of a petition presented to a County Court, may not have been notified to the Central Index and entered on such records at all, and the response to an enquiry only relates to the period of six months prior to the date when the enquiry was made. We have not made enquiries of any County Court as to whether a petition for the appointment of an administrator has been presented to, or an administration order has been made by, any County Court against Tronox.

We express no opinion as to, nor have we taken into account, the implications of any pending or foreshadowed legislative or regulatory proposal or amendment or of any litigation, hearing or pending judgment in England and Wales including, but not limited to, any matters not yet decided on appeal.

We consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder. Except as otherwise stated in this opinion letter, this opinion letter may not be relied upon for any other purpose or by any other person.

This opinion letter is given by CMS Cameron McKenna Nabarro Olswang LLP which assumes liability, and is responsible, for it. No individual owes or shall owe any duty of care to any person for this opinion letter and Tronox agrees that each member, employee and consultant of CMS Cameron McKenna Nabarro Olswang LLP shall be entitled to the benefit of the provisions of this paragraph under the Contract (Rights of Third Parties) Act 1999.

This opinion is being furnished to you in connection with the filing of the Registration Statement and in accordance with the requirements of Item 601(b)(5)(i) of Regulation S-K promulgated under the Securities Act.

Yours faithfully

CMS Cameron McKenna Nabarro Olswang LLP
