This document contains forward-looking statements under Canadian securities legislation. Forward-looking statements include, but are not limited to, statements with respect to the development potential and timetable of the Rosita project; the timing and amount of estimated future development and exploration; costs of future activities; capital and operating expenditures; success of exploration activities; government regulation of mining operations; and environmental risks. Generally, forward-looking statements can be identified by the use of forward-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 statements are based on the opinions and estimates of management as of the date such statements are made. Forward-looking statements are subject to known and unknown risks, uncertainties and other factors that may cause the actual results, level of activity, performance or achievements of the Company to be materially different from those expressed or implied by such forward-looking statements, including but not limited to risks related to: timing and availability of external financing on acceptable terms; unexpected events and delays during construction, expansion and start-up; variations in ore grade and recovery rates; receipt and revocation of government approvals; actual results of exploration and mining activities; changes in project parameters as plans continue to be refined; future prices of metals; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining industry. Although management of the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. The Company does not undertake to update any forward-looking statements except in accordance with applicable securities laws.

The technical and scientific information included herein has been reviewed and approved by Joseph Arengi, M.Sc., P.Geo , President and CEO of the Company, and a qualified person under National Instrument 43-101 of the Canadian Securities Administrators.

All of the historical mineral resource estimates and production totals quoted herein are based upon historical data and reports obtained and prepared by previous operators and consultants (Arengi, 2003; Hendrickson, 1995; Rivera, 1977; Rosario, 1974; Sims, 1998) and the quoted mineral resource estimates/mineral inventory were prepared prior to the introduction of National Instrument 43-101. These historic resource estimates/mineral inventory are considered to be relevant to the evaluation of the Rosita D concession. A Qualified Person has not completed the work necessary to independently verify the classification of the historic mineral resource estimates. Alder is not treating the mineral resource estimates as National Instrument 43-101 compliant defined resources verified by a Qualified Person. The historical estimates should not be relied upon.

Notes on Mineral Resource Estimation1. The mineral resource estimate base case is reported at a 0.15% copper equivalent cut-off grade; this cut-off incorporates consideration of mining and processing cost, recoveries, commodity prices and selling cost.2. The mineral resource estimate is reported on an undiluted basis.3. The mineral resource estimate assumes a long term copper price of US$2.90/lb, a gold price of US$1,200/oz and a silver price of US$24/oz.4. Rounding as required by NI 43-101 reporting guidelines may result in apparent summation differences between tonnes, grade and contained metal content.5. Tonnage and grade measurements are in metric units. Contained gold and silver ounces are reported as troy ounces, contained copper pounds as imperial pounds.6. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant

issues.7. The quantity and grade of reported inferred mineral resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred mineral resources as indicated or measured mineral resources and it is

uncertain if further exploration will result in upgrading them to indicated or measured mineral resources.
