2 Based on 151,473,234 common shares of Augusta outstanding as of September 23, 2014 as disclosed by Augusta to Hudbay.

This Amendment No. 7 (this “Amendment”) amends the Schedule 13D filed by Hudbay on August 27, 2010 (the “Schedule 13D”) and amended on March 18, 2011, April 17, 2013, February 10, 2014, June 23, 2014, July 17, 2014 and July 30, 2014, with respect to the Common Shares. The Common Shares to which this Amendment relates are held directly by Hudbay. This Amendment is being filed to amend the Schedule 13D, as amended, in light of recent events.

Item 4. Purpose of the Transaction

Item 4 is supplemented as follows:

(h) Delisting of Augusta from the NYSE MKT LLC (the “Exchange”)

Trading of the Common Shares has been suspended effective September 23, 2014. Also on September 23, 2014, the Exchange has filed a Form 25 notification with the Commission relating to the removal of the Common Shares from listing on the Exchange. Augusta intends to file a Form 15 with the Commission once it meets the criteria for terminating its reporting obligations under the Act.

Item 5. Interest in Securities of the Issuer

Item 5 is supplemented as follows:

(a)-(b) On September 23, 2014, the amalgamation of Augusta and Newco became effective pursuant to the Amalgamation Agreement. The resulting continuing corporation is an indirect, wholly-owned subsidiary of Hudbay. Accordingly, Hudbay has acquired the 6,396,780 Common Shares not already owned by Hudbay or its affiliates.

Including the additional 6,396,780 Common Shares acquired pursuant to the Amalgamation Agreement, Hudbay owns 151,473,234 Common Shares, representing 100% of the issued and outstanding Common Shares.

The following information with respect to the ownership of the Common Shares by Hudbay is provided as of September 23, 2014:
