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.
