CONSTANCIA MINE SITE VISIT September 2014
CONSTANCIA PRESENTATION l 2
Forward Looking Information This presentation contains “forward-looking statements” and “forward-looking information” (collectively, “forward-looking information”) within the meaning of applicable Canadian and United States securities legislation. All information contained in this presentation, other than statements of current and historical fact, is forward-looking
“estimates”, “forecasts”, “strategy”, “target”, “intends”, “objective”, “goal”, “understands”, “anticipates” and “believes” (and variations of these or similar words) and statements that certain actions, events or results “may”, “could”, “would”, “should”, “might” “occur” or “be achieved” or “will be taken” (and variations of these or similar expressions). All of the forward-looking information in this presentation is qualified by this cautionary note. Forward looking information includes, but is not limited to, statements with respect to the anticipated timing, mechanics, completion of the subsequent acquisition transaction to acquire the remaining shares of Augusta Resource Corporation (“Augusta”) the permitting, development and financing of Augusta’s Rosemont copper project (the “Rosemont project”), Hudbay’s objectives, strategies, intentions, expectations and guidance and future financial and operating performance and prospects, production at Hudbay’s 777, Lalor and Reed mines and initial production from the Constancia project, continued processing at Hudbay’s Flin Flon concentrator, Snow Lake concentrator and Flin Flon zinc plant, Hudbay’s ability to complete the development of Hudbay’s Lalor and Constancia projects and the anticipated scope and cost
Silver Wheaton Corp. (“Silver Wheaton”) and that additional funding will be available if needed under Hudbay’s standby credit facility for Constancia, the anticipated effect of external factors on revenue, such as commodity prices, anticipated exploration and development expenditures and activities and the possible success of such activities, estimation of mineral reserves and resources, mine life projections, timing and amount of estimated future production, reclamation costs, economic outlook, government regulation of mining operations, and business and acquisition strategies. 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 Hudbay identified and were applied by the company in drawing conclusions or making forecasts or projections set out in the forward looking information include, but are not limited to: the success of mining, processing, exploration and development activities; the accuracy of geological, mining and metallurgical estimates; the costs of production; the supply and demand for metals Hudbay produces; no significant and continuing adverse changes in financial markets, including commodity prices and foreign exchange rates; the supply and availability of reagents for Hudbay’s concentrators; the supply and availability of concentrate for Hudbay’s processing facilities for the company’s concentrate; the supply and the availability of third party processing facilities for Hudbay’s concentrate; the supply and availability of all forms of energy and fuels at reasonable prices; the availability of transportation services at reasonable prices; no significant unanticipated operational or technical difficulties; the execution of Hudbay’s business and growth strategies, including the success of Hudbay’s strategic investments and initiatives; the availability of financing for Hudbay’s exploration and development projects and activities; the ability to complete project targets on time and on budget and other events that may affect Hudbay’s ability to develop Hudbay’s projects; the timing and receipt of various regulatory and governmental approvals; the availability of personnel for Hudbay’s exploration, development and operational projects and ongoing employee relations; Hudbay’s ability to secure required land rights to complete its Constancia project; maintaining good relations with the communities in which Hudbay operates, including the communities surrounding the Constancia project and First Nations communities surrounding the Lalor project and Reed mine; no significant unanticipated challenges with stakeholders at Hudbay’s various projects, including the company’s newly acquired Rosemont project; no significant unanticipated events or changes relating to regulatory, environmental, health and safety matters; no contests over title to Hudbay’s properties, including as a result of rights or claimed rights of aboriginal peoples; the timing and possible outcome of pending litigation and no significant unanticipated litigation; certain tax matters, including, but not limited to current tax laws and regulations and the refund of certain value added taxes from the Canadian and Peruvian governments; no significant and continuing adverse changes in general economic conditions or conditions in the financial markets; and the timing and completion of a subsequent acquisition transaction in connection with Hudbay’s acquisition of Augusta.
CONSTANCIA PRESENTATION l 3
Forward Looking Information (continued) 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, the development of the Rosemont project not occurring as planned, the exercising of dissent and appraisal rights by Augusta shareholders should a subsequent acquisition transaction be undertaken in connection with Hudbay’s acquisition of Augusta, Augusta continuing as a majority-owned subsidiary of Hudbay should a subsequent acquisition transaction not be completed, the inaccuracy of Augusta’s public disclosure and representations in the support agreement upon which Hudbay’s
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 Hudbay’s projects (including the impact on project cost and schedule of construction delays and unforeseen risks and other factors beyond the company’s control), depletion of Hudbay’s reserves, risks related to political or social unrest or change and those in respect of aboriginal and community relations, rights and title claims,
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 Hudbay’s 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 its pension and other post-retirement obligations, the company’s ability to abide by the covenants in Hudbay’s debt instruments or other material contracts, tax refunds, hedging transactions, as well as the risks discussed under the heading “Risk Factors” in this presentation and 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, you 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 presentation or to explain any material difference between subsequent actual events and any forward-looking information, except as required by applicable law.

The scientific and technical information in respect of Hudbay contained in this presentation related to the Constancia project has been prepared by or under the supervision of Cashel Meagher, P.Geo., Hudbay’s Vice President, South America Business Unit. The scientific and technical information related to all other sites and projects of Hudbay contained in this presentation has been prepared by or under the supervision of Robert Carter, P.Eng., Hudbay’s Director, Technical Services. Messrs. Meagher and Carter are Qualified Persons for the purposes of NI 43-101 – Standards of Disclosure for Mineral Projects. (“NI 43-101”). The mineral reserve and resource estimates included in
Metallurgy and Petroleum Standards on Mineral Resources and Reserves: Definitions and Guidelines. Mineral resources that are not mineral reserves do not have demonstrated economic viability. For a description of the key assumptions, parameters and methods used to estimate mineral reserves and resources, as well as data verification procedures and a general discussion of the extent to which the estimates may be affected by any known environmental, permitting, legal, title, taxation, socio-political, marketing or other relevant factors, please see the Technical Reports for each of Hudbay’s properties as filed on SEDAR at www.sedar.com. The disclosure in this presentation uses mineral resource classification terms and mineral resource estimates that comply with NI 43-101. NI 43-101 establishes standards for all public disclosure a Canadian issuer makes of scientific and technical information concerning mineral
These standards differ significantly from the mineral reserve disclosure requirements of the SEC set forth in Industry Guide 7. Consequently, reserve and resource information contained herein is not comparable to similar information that would generally be disclosed by U.S. companies in accordance with the rules of the SEC. In particular, the SEC’s Industry Guide 7 applies different standards in order to classify mineralization as a reserve. As a result, the definitions
may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Among other things, all necessary permits would be required to be in hand or their issuance imminent in order to classify mineralized material as reserves under the SEC standards. Accordingly, mineral reserve estimates referred to herein may not qualify as “reserves” under SEC standards. In addition, the terms “measured mineral resources,” “indicated mineral resources” and “inferred mineral resources” are used to comply with the reporting standards in Canada. The SEC’s Industry Guide 7 does not recognize mineral resources and U.S. companies are generally not permitted to disclose resources in documents they file with the SEC. Investors are specifically cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into SEC defined mineral reserves. Further, “inferred resources” have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, investors are also cautioned not to assume that all or any part of an inferred resource exists. It cannot be assumed that all or any part of “measured mineral resources,” “indicated mineral resources,” or “inferred mineral resources” will ever be upgraded to a higher category. Investors are cautioned not to assume that any part of the reported “measured mineral resources,” “indicated mineral resources,” or “inferred mineral resources” contained herein is economically or legally mineable. For the above reasons, information contained herein containing descriptions of mineral reserve and resource estimates is not comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC.

For additional details relating to the estimates of mineral reserves and resources at the Constancia project, including data verification and quality assurance/quality control processes refer to “The Constancia Project, National Instrument 43-101 Technical Report” as filed on SEDAR by Hudbay on November 6, 2012.
The Constancia and Pampacancha mineral reserves are based on a Peruvian Sole: US Dollar exchange rate of 2.85:1 and the following long term metals prices: copper price of US$3.00 per pound; silver price of US$25.00 per ounce; gold price of US$1,250.00 per ounce; and molybdenum price of US$13.50 per pound.
The Constancia and Pampacancha mineral resources correspond to a resources pit shell. A pit optimization to delimit the portion of the block model having reasonable prospects for economic extraction was performed.
The Constancia resource pit consists of a non-operational pit of Measured, Indicated and Inferred resources diluted to a 10x10x15m full block size using a 0.12% copper cut-off based on a copper price of US$2.88 per pound and a molybdenum price of US$16.00 per pound, copper recovery of 89%, molybdenum recovery of 60%, processing costs of US$5.50 per tonne and mining costs of US$1.30 per tonne.
The Pampacancha resource pit consists of a non-operational pit of Measured, Indicated and Inferred resources diluted to a 10x10x15m full block size using a 0.1% copper cut-off based on a copper price of US$3.00 per pound, a molybdenum price of US$13.50 per pound, silver price of US$25.00 per ounce, gold price of US$1,250 per ounce, copper recovery of 85%, molybdenum recovery of 40%, gold and silver recovery of 65%; processing costs of US$4.72 per tonne and mining costs of US$1.90 per tonne.
The primary consideration to accommodate the increased Constancia mineral reserve in the Constancia life of mine plan (“LOM”) was the confirmation through pre-feasibility investigation to increase the tailings dam height to accommodate this extra tonnage and the waste rock facility configuration. The resulting LOM has increased to 22 years from 16 years. In this process some of the major cost components have been updated to reflect some known actual costs such as energy, fuel, concentrate transport and port charges. The resulting change is an average cost of US$0.72 per pound of copper produced net of by product credits from a previously disclosed US$0.66 per pound of copper in the first full five years of production. Contained copper metal in concentrate is expected to average 116,000 tonnes per year over the first five full years versus 118,000 tonnes as previously disclosed. Over the remaining years, the cost per pound of copper net of by product credits has increased to US$1.14 per pound from US$1.11 per pound; and the contained copper metal in concentrate is expected to average 67,000 tonnes per year versus 77,000 tonnes per year as previously disclosed. The cost per pound of copper net of by product credits does not include the impact of the precious metals streaming transactions.
Measured and indicated mineral resources were estimated in house. The process includes determination of the integrity and validation of the data collected, including confirmation of specific gravity, assay results and methods of data recording. The process also includes determining the appropriate geological model, selection of data and the application of statistical models including probability plots to establish continuity and model validation.
