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

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 verified the historic drill results reported herein and does not intend to use this

information for purposes other than planning and prioritizing exploration targets.
