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.

Notes to Text

• Note 1: See references in Alder Technical Report referred to in News Release of January 9, 2012 and filed on SEDAR.

• Note 2: 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.

• Note 3: Alder has not yet done sufficient work to verify the historic drill results reported in this news release and does not intend to use this information for purposes other than planning and prioritizing exploration targets.
