Corporate Update Summary

The Company has made significant advancements in the Rosita porphyry/skarn project including completion of 5,900 metres of diamond drilling in 20 holes, 1,500 metres of reverse circulation drilling on stockpiles leading to a NI 43-101 compliant inferred mineral resource, ground Induced Polarization and magnetic surveys, soil sampling surveys, excavation of 16 trenches and completion of a detailed mineralogical study of the stockpile resource. Highlights include:

--  Definition of a 7.95 million tonne inferred mineral resource grading
    0.62% Cu, 0.46 g/t Au and 9.2 g/t Ag for the mine stockpiles (see news
    release dated May 9, 2012);

--  Completion of 18 diamond drill holes at Santa Rita resulting in the
    delineation of a 1,100 metre long trend of Cu-Au-Ag skarn
    mineralization;

--  Discovery of a high grade gold zone that overprints the skarn
    mineralization at Santa Rita;

--  Discovery of a high grade Cu+Au+Ag supergene enriched blanket at
    Tipispan that includes 7.48% Cu, 2.36 g/t Au and 316.13 g/t Ag over 6.5
    metres and 5.21% Cu, 4.4 g/t Au and 144.01 g/t Ag over 12.1 metres in
    trenches; and

--  Identification of high grade (1-2% Cu) exotic Cu-Au-Ag mineralization in
    the Bambana area;

Moving Forward

The Company intends to focus efforts primarily on two aspects of the project in 2013. Exploration will continue at the Tipispan porphyry target and may include detailed soil sampling, trenching and drilling. In addition, Alder is currently exploring ways to advance the development of the stockpile resource, including metallurgical studies, economic modeling and a scoping study with respect to a small scale production facility.

Quality Assurance/Quality Control

Alder has implemented an industry standard Quality Assurance/Quality Control program that includes the insertion of certified standards and blanks into the sample stream. Samples were collected into heavy gauge plastic bags, sealed on-site, then stored at Alder's Rosita field office until transported by company or laboratory personnel to Inspectorate Exploration and Mining Services' sample preparation facility in Managua. In Managua, pulps were prepared for shipping to Inspectorate's Analytical laboratory in Reno, Nevada, where each sample was analyzed via 1 assay-tonne fire assay for gold and 30 element ICP (Inductively Coupled Plasma-atomic emission spectrometry) methods for copper, silver and 28 other elements.

Qualified Person

Joseph Arengi, M. Sc., P. Geo., President and Chief Executive Officer of Alder and a qualified person as defined by NI 43-101, has reviewed and approved the scientific and technical content of this news release.

About Alder Resources Ltd.

Alder is a resource company focused on the development of gold and base metal projects throughout the Americas. Alder's current high priority Cu-Au-Ag porphyry target is the Rosita project in Nicaragua located 275 kilometres northeast of Managua. The company has current Inferred mineral stock pile resources of 7.95 million tonnes grading 0.62% Cu, 0.46 g/t Au and 9.21 g/t Ag with numerous zones that have good near term potential to add to and enhance these resources. See the technical report entitled "Rosita Cu-Au-Ag Project, RAAN, Nicaragua, NI 43-101 Technical Report on Mineral Resource Estimate of Rosita Stockpiles" effective as of May 8, 2012, which is available under the Company's profile at www.sedar.com. Alder is also highly encouraged by recent trench results that, in conjunction with previous drill results from the Tipispan area, support management's belief of a large, untested, copper-gold-silver porphyry/skarn system locally overlain by a high grade, supergene enriched, oxide blanket.

In August 2011, Alder entered into an option agreement to acquire a 65% interest in the Rosita D concession from Calibre Mining Corp. by issuing 1,000,000 shares and incurring expenditures of $4,000,000 over four years. To date Alder has incurred more than half of the $4,000,000 earn-in obligation.

Alder intends to continue to build its property position with strategic acquisitions.
