2 Forward-Looking Statements All monetary amounts in Canadian dollars unless otherwise stated.. This presentation contains forward-looking information within the meaning of applicable Canadian securities legislation and United States securities laws. Forward-looking information includes, but is not limited to, information concerning the proposed business combination between HudBay Minerals and Lundin Mining and the business, operations and financial performance and condition of the combined company, such as the estimated production and mine life of the various mineral projects of HudBay Minerals and Lundin Mining; synergies and the financial impact of the completed proposed transaction; potential benefits of the transaction and the development potential of the properties of HudBay Minerals and Lundin Mining; the future price of zinc, copper, nickel, lead, cobalt, gold and silver; the estimation of mineral reserves and resources; the realization of mineral reserve estimates; the timing and amount of estimated future production; capital cost estimates, estimated costs of production; success of exploration activities; and currency exchange rate fluctuations. Generally, forward-looking information can be identified by the use of forwarding-looking terminology, such as "plans", "expects", or "does not expect", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates", or "does not anticipate", or "believes" or variations of such words and phrases or statements that certain actions, events or results "may", "could", "would", "might", or "will be taken", "occur", or "be achieved". Forward-looking information is based on the opinions and estimates of management at the date the information is provided, and is based on a number of assumptions and subject to a variety of risks and uncertainties and other factors that could cause actual events or results to differ materially from those projected in the forward-looking statements. Assumptions upon which such forward looking information are based include, without limitation, that the shareholders of Lundin Mining will approve the transaction, that all required third party regulatory and governmental approvals to the transaction, the Loan, and the Private Placement will be obtained and all other conditions to completion of the transaction, the loan, and the Private Placement will be satisfied or waived. Many of these assumptions are based on factors and events that are not within the control of HudBay Minerals or Lundin Mining and there is no assurance they will prove to be correct. Factors that could cause actual results to vary materially from results anticipated by such forward-looking information include changes in market conditions, variations in ore grade or recovery rates, risks relating to international operations, fluctuating metal prices and currency exchange rates, changes in project parameters, the possibility of project cost overruns or unanticipated costs and expenses, labour disputes and other risks of the mining industry, failure of plant, equipment or processes to operate as anticipated, the inability to obtain key personnel and parts related to the construction of mining operations, the business of the companies not being integrated successfully or such integration proving more difficult, time consuming or costly than expected as well as those risk factors discussed in the Annual Information Form for the year ended December 31, 2007 for each of HudBay Minerals and Lundin Mining available at Although HudBay Minerals and Lundin Mining have attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking information, there may be other factors that cause actions, events or results not to be anticipated, estimated or intended. There can be no assurance that forward-looking information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such information. HudBay Minerals undertakes no obligation to update forward-looking information if circumstances or management s estimates or opinions should change except as required by applicable securities laws. The reader is cautioned not to place undue reliance on forward-looking information. Information concerning mineral reserve and resource estimates may also be deemed to constitute forward-looking information to the extent they involve estimates of the mineralization that will be encountered if the property is developed. Comparative market information is as of a date prior to the date of this presentation. This presentation and the information contained herein does not constitute an offer of securities for sale in the United States and securities may not be offered or sold in the United States absent registration or exemption from registration. CAUTIONARY NOTE TO U.S. INVESTORS CONCERNING ESTIMATES OF MEASURED, INDICATED AND INFERRED RESOURCES This presentation uses the terms Measured, Indicated and Resources as defined in accordance with National Instrument Standards of Disclosure for Mineral Projects. United States readers are advised that while such terms are recognized and required by Canadian securities laws, the United States Securities and Exchange Commission does not recognize them. Under United States standards, mineralization 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 calculation is made. United States readers are cautioned not to assume that all or any part of the mineral deposits in these categories will ever be converted into reserves. In addition, Resources have a great amount of uncertainty as to their existence, and as to their economic and legal feasibility. It cannot be assumed that all or any part of an Resource will ever be upgraded to a higher category. United States readers are also cautioned not to assume that all or any part of an Resource exists, or is economically or legally mineable. 2

8 Quality Assurance and Quality Control, Qualified Person Quality Assurance and Quality Control Exploration core drilling was either BQ or NQ size. The core was logged and mineralized intersections were marked for sampling and assaying by geologists and geotechnicians employed by HudBay's Hudson Bay Exploration and Development Company Limited (HBED) subsidiary. The marked intersections or intervals were sawn in half by a diamond saw and one half of the core was placed in plastic bags and tagged with unique sample numbers, while the second half was returned to the core box and stored. Each bagged core sample was transported to HudBay's Hudson Bay Mining and Smelting Co., Limited subsidiary's assay laboratory in Flin Flon, Manitoba where it was dried, crushed and pulverized and a 250-gram sample was prepared for assaying. From each 250 gram sample 0.25 grams was removed and leached in aqua regia and analyzed by ICP-AES for Ag, Cu, Zn, As, Pb, Ni and Fe. Also from the 250-gram sample, 15 grams was removed for gold determination by fire assaying with Atomic Absorption finish. Assaying integrity is monitored internally with a quality control program, which includes the use of assay sample standards, blanks, duplicates and repeats and externally through national and international programs. In addition, within each group of 20 core samples, one core sample has a second 250 gram split collected for check assaying at Acme Analytical Laboratories Ltd. in Vancouver, B.C. This news release provides core lengths and additionally where indicated, calculated vertical thickness of mineralization intersected. True widths are not provided. Where metal assays are provided for intersections they are either a single assay of a sample of the entire intersection length or a composite of assays calculated from interval weighted assays over the intersection length. Qualified Person The data herein and the contents of this news release have been reviewed by Kelly Gilmore, B.Sc. P. Geo., Chief Exploration Geologist with HBED, who is a Qualified Person within the meaning of NI , with the ability and authority to verify the authenticity and validity of the data. 8
