I. PURPOSE OF FILING:

St Barbara Limited, or St Barbara, a company organized under the laws of the Commonwealth of Australia, is submitting this Form 6-K to establish itself, pursuant to Rule 12g-3 of the U.S. Securities Exchange Act of 1934, or the Exchange Act, as the successor issuer to Allied Gold Mining Limited (and its predecessor entities Allied Gold Mining PLC and Allied Gold Limited as applicable), or Allied Gold, a company organized under the laws of England and Wales.

II. BACKGROUND AND SUCCESSION PURSUANT TO RULE 12g-3:

On July 18, 2012, St Barbara and Allied Gold entered into a preliminary Scheme of Arrangement, which was approved by the shareholders of Allied Gold at a meeting held on August 14, 2012. Pursuant to an order of the High Court of Justice of England & Wales, the Scheme of Arrangement became effective on August 30, 2012 with St Barbara completing the acquisition of 100% of the issued capital of Allied Gold, the Allied Gold Acquisition, on September 7, 2012. As a result of the Allied Gold Acquisition, St Barbara became the holder of all issued and outstanding shares of Allied Gold.

As a consequence of, and following, the Allied Gold Acquisition, shares of St Barbara were deemed to be registered under
Section 12(g) of the Exchange Act pursuant to Rule 12g-3(a) thereunder, without the filing of a registration statement therefor. Accordingly, St Barbara is a reporting issuer under the Exchange Act in succession to Allied Gold, and reports filed for Allied Gold under the Exchange Act should be regarded as applicable to St Barbara, as successor issuer.
