TORONTO, ON–(Marketwired – November 28, 2016) – HudBay Minerals Inc. (“Hudbay” or the “company”) (TSX: HBM) (NYSE: HBM) today announced that it is offering US$1.0 billion aggregate principal amount of senior notes in two series, including a series of senior notes due 2023 (the “2023 Notes”) and a series of senior notes due 2025 (the “2025 Notes” and, together with the 2023 Notes, the “New Notes”). The aggregate principal amount, interest rate and other terms of each series of the New Notes will be determined at pricing and are dependent upon market conditions and other factors.

Hudbay also announced today that it is commencing an offer to purchase for cash (the “Tender Offer”) any and all of its outstanding US$920 million aggregate principal amount of 9.500% senior notes due 2020 (the “Existing Notes”) on the terms and subject to the conditions set forth in an offer to purchase and consent solicitation statement dated November 28, 2016 (the “Offer to Purchase”). Hudbay concurrently announced that it is soliciting consents (the “Consent Solicitation”) from holders of the Existing Notes to amend the indenture governing the Existing Notes to reduce the minimum notice period required for redemptions of the Existing Notes from 30 to 3 days on the terms and subject to the conditions set forth in the Offer to Purchase. The Tender Offer is scheduled to expire at 12:00 midnight (end of day), New York City time, on December 23, 2016 unless extended or earlier terminated (such date and time, as it may be extended or earlier terminated, the “Expiration Date”). The Consent Solicitation is scheduled to expire at the Early Tender Time (as defined below) unless extended or earlier terminated.

Subject to the terms and conditions of the Tender Offer, holders who validly tender and do not withdraw their Existing Notes on or prior to 5:00 p.m., New York City time, on December 9, 2016, unless extended or earlier terminated by Hudbay (such time and date, as the same may be extended or earlier terminated, the “Early Tender Time”) will be eligible to receive total consideration of US$1,052.50 per US$1,000 principal amount of Existing Notes tendered and accepted for payment by Hudbay, which includes an early tender premium of US$30.00 for each US$1,000 principal amount of Existing Notes tendered. Holders who validly tender their Existing Notes after the Early Tender Time and at or prior to the Expiration Date will only be eligible to receive US$1,022.50 per US$1,000 principal amount of Existing Notes tendered. Holders who validly tender their Existing Notes pursuant to the Tender Offer prior to the Early Tender Time will be deemed to have validly delivered consents related to such Existing Notes (the “Consents”) in the Consent Solicitation. Hudbay’s obligation to complete the Tender Offer is subject to and conditional upon completion of the offering of the New Notes as well as customary conditions. Hudbay’s obligation to complete the Consent Solicitation is conditional upon the receipt prior to the Early Tender Time of Consents from holders of a majority in aggregate principal amount of the Existing Notes then outstanding voting as a single class and the execution of a supplemental indenture reflecting the proposed amendment to the indenture governing the Existing Notes.

Hudbay plans to use the net proceeds from the offering of the New Notes (i) to fund the Tender Offer and to pay expenses associated with the Tender Offer and Consent Solicitation and the offering of the New Notes, (ii) to fund the redemption or satisfaction and discharge of any Existing Notes that remain outstanding following consummation of the Tender Offer and (iii) for general corporate purposes.

Hudbay also announced today that, in connection with the offering, one of its lenders has agreed to increase its commitment under Hudbay’s senior secured revolving credit facilities by US$20 million, conditional upon completion of the offering of the New Notes. The additional US$20 million commitment would increase the total commitments under Hudbay’s senior secured revolving credit facilities to US$550 million and further improve the company’s liquidity.

The New Notes will not be registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any other jurisdiction. The New Notes will not be qualified by a prospectus in Canada. Unless they are registered or qualified by a prospectus, the New Notes may be offered only in transactions that are exempt from registration under the Securities Act, prospectus qualification under Canadian securities laws or the securities laws of any other jurisdiction. In the United States, the New Notes will be offered, and sold, only to “qualified institutional buyers” (as defined in Rule 144A under the Securities Act) and outside the United States to non-U.S. persons in compliance with Regulation S under the Securities Act.

This press release is neither an offer to sell nor the solicitation of an offer to buy the New Notes, the Existing Notes or any other securities and shall not constitute an offer to sell or solicitation of an offer to buy, or a sale of, the New Notes, the Existing Notes or any other securities in any jurisdiction in which such offer, solicitation or sale is unlawful. This press release does not constitute a notice of redemption with respect to the Existing Notes.
