Hudbay Announces...

Note Offering

The Notes have not been registered under the U.S. Securities Act of 1933, as amended (the "Securities Act"), or the securities laws of any other jurisdiction. The Notes have not been qualified by a prospectus in Canada. Unless they are registered or qualified by a prospectus, the 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 Notes will be offered 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. In connection with the offering of the Notes, Hudbay expects to enter into a registration rights agreement pursuant to which it will agree to offer to exchange the Notes for identical new notes registered under the Securities Act or, under certain circumstances, to cause a shelf registration statement providing for the resale of the notes to become effective.

The Notes will constitute a part of the same series of notes as the Existing Notes for all purposes of the indenture, although the Notes will not initially be fungible with the Existing Notes. Exchange notes issued in connection with the exchange offer Hudbay is required to conduct pursuant to the registration rights agreement are expected to be fungible and have the same CUSIP number as the Existing Notes.

This news release is neither an offer to sell nor the solicitation of an offer to buy the 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 Notes or any other securities in any jurisdiction in which such offer, solicitation or sale is unlawful.

Cautionary Note Regarding Forward Looking Information

This news release contains "forward-looking statements" and "forward-looking information" (collectively, "forward-looking information") within the meaning of applicable Canadian and United States securities legislation. Forward-looking information includes information that relates to, among other things, our objectives, strategies, and intentions and future financial and operating performance and prospects, our intention to complete the proposed offering and the subsequent exchange offer and our expectations as to the use of proceeds from the offering. Forward-looking information is not, and cannot be, a guarantee of future results or events. Forward-looking information is based on, among other things, opinions, assumptions, estimates and analyses that, while considered reasonable by us at the date the forward-looking information is provided, inherently are subject to significant risks, uncertainties, contingencies and other factors that may cause actual results and events to be materially different from those expressed or implied by the forward-looking information. The material factors or assumptions that we identified and were applied by us in drawing conclusions or making forecasts or projections set out in the forward looking information include, but are not limited to, the execution of our business strategy, including the success of our strategic investments and initiatives; the availability of financing for our exploration and development projects and activities; the ability to complete project targets on time and on budget and other events that may affect our ability to develop our projects; no significant and continuing adverse changes in general economic conditions or conditions in the financial markets; and Hudbay's intentions with respect to Augusta.

The risks, uncertainties, contingencies and other factors that may cause actual results to differ materially from those expressed or implied by the forward-looking information may include, but are not limited to, risks generally associated with the mining industry, such as economic factors (including future commodity prices, currency fluctuations, energy prices and general cost escalation), uncertainties related to the development and operation of the company's projects (including the impact on project cost and schedule of construction delays and unforeseen risks and other factors beyond our control), depletion of its reserves, risks related to political or social unrest or change and those in respect of aboriginal and community relations and title claims, operational risks and hazards, including unanticipated environmental, industrial and geological events and developments and the inability to insure against all risks, failure of plant, equipment, processes, transportation and other infrastructure to operate as anticipated, compliance with government and environmental regulations, including permitting requirements and anti-bribery legislation, dependence on key personnel and employee relations, volatile financial markets that may affect our ability to obtain financing on acceptable terms, uncertainties related to the geology, continuity, grade and estimates of mineral reserves and resources and the potential for variations in grade and recovery rates, uncertain costs of reclamation activities, Hudbay's ability to comply with the company's pension and other post-retirement obligations, Hudbay's ability to abide by the covenants in the company's debt instruments, as well as the risks discussed under the heading "Risk Factors" in Hudbay's most recent annual information form. Should one or more risk, uncertainty, contingency or other factor materialize or should any factor or assumption prove incorrect, actual results could vary materially from those expressed or implied in the forward-looking information. Accordingly, the reader should not place undue reliance on forward-looking information. Hudbay does not assume any obligation to update or revise any forward-looking information after the date of this news release or to explain any material difference between subsequent actual events and any forward-looking information, except as required by applicable law.
