Amendment: First Quantum Minerals Announces Senior Notes Offering

TORONTO, ONTARIO–(Marketwired – March 10, 2017) –

(In United States dollars, except where noted otherwise)

First Quantum Minerals Ltd. (“First Quantum” or the “Company”) (TSX:FM) today announced that it is launching an offering of $1,600 million of Senior Notes due 2023 and 2025 (the “Notes”).

The Notes will be senior obligations of the Company and will be guaranteed by certain of the Company’s subsidiaries. Interest will be payable semi-annually. The interest rate, offering price and principal amount of each series of the Notes along with certain other terms will be determined at the time of pricing of the offering, subject to market conditions.

The Company intends to use the proceeds of the offering to refinance the Company’s existing senior notes due 2019 and 2020 by way of a tender offer and redemption, repay certain other senior debt and pay fees associated with the offering. The Company has prepared an offering memorandum which will be made available to selected prospective purchasers of the Notes.

This announcement is not an offer of securities for sale in the United States or any other jurisdiction. Securities may not be offered or sold in the United States unless they are registered or are exempt from registration. The Company does not intend to register any portion of this offering in the United States or to conduct a public offering in the United States or any other jurisdiction. Any public offering of securities to be made in the United States would be made by means of a prospectus that would contain detailed information about the Company and its management, as well as financial statements.

The Company and others will rely upon the truth and accuracy of the foregoing representations and agreements.
