VANCOUVER, BRITISH COLUMBIA–(Marketwired – Nov. 27, 2013) – First Quantum Minerals Ltd. (“First Quantum” or the “Company”) (TSX:FM)(LSE:FQM) today announced that its wholly-owned subsidiary FQM (Akubra) Inc. (“Akubra”) has received a notice purporting to call a default from a limited number of noteholders holding notes originally issued by Inmet Mining Corporation (“Inmet”), including CI Investments, Barometer Capital and funds managed by Capital Group (the “Noteholder Group”). First Quantum strongly disputes that any default has occurred.

As a result of First Quantum’s takeover of Inmet, FQM (Akubra) Inc. (“Akubra”) amalgamated with Inmet, with the amalgamated entity continuing as a wholly-owned subsidiary of First Quantum. The Noteholder Group alleges that Inmet violated the terms of the indentures of Inmet’s 8.75% Senior Notes due 2020 and Inmet’s 7.5% Senior Notes due 2021 (the “Indentures”) when Inmet amalgamated with Akubra and the amalgamated entity subsequently repaid the acquisition financing originally incurred by Akubra.

First Quantum has considered carefully the arguments of the Noteholder Group and strongly disputes that a default has occurred. Moreover, First Quantum firmly believes based on legal advice that even if the transaction resulted in a breach of the Indentures, the only remedy available to the Noteholder Group under the Indentures would be acceleration of the debt and repayment at par, which would reflect a significant discount to current trading prices. Throughout the transaction, First Quantum has been advised by one of the leading New York-based law firms specialized in credit instruments. Since these allegations were first made, First Quantum also confirmed the strength of its position with a second leading New York-based law firm.

First Quantum retains very strong credit and a robust balance sheet, as is demonstrated by the signed extension commitment with Standard Chartered Bank announced October 30, 2013. This commitment extends the existing Akubra revolving credit facility until June 30, 2014, with the full amount of the facility remaining available until this date. First Quantum have a long-standing relationship with Standard Chartered Bank as well as the benefit of relationships with a number of other key commercial banks who have acknowledged their continued support of the business. The Company’s principal banks have been kept fully informed in relation to the claims of the Noteholder Group.

Philip Pascall, First Quantum’s Chairman and Chief Executive, commented:

“First Quantum strongly disputes the claims of the Noteholder Group in relation to the Inmet indentures. These claims are without legal foundation, highly opportunistic, and run the risk of destroying value for all Inmet noteholders, a large proportion of which are not part of the Noteholder Group.

We remain very confident in the strength of our legal position and we intent to take immediate legal action to enforce it. We will also remain open to reaching an amicable resolution.”
