Drilling At Rosita Stockpiles Exceeds Expectations  

TORONTO, ON - Alder Resources Ltd. Reported assay results for the final 31 vertical reverse circulation ("RC") drill holes from stockpile material at the Santa Rita and R-13 areas, as well as trenching results from the Bambana prospect, located within the Company's 33.56 square kilometre Rosita project in northeast Nicaragua.

The weighted average grade of all RC drill results from the stockpiles returned 0.49% copper ("Cu"), 0.42 g/t gold ("Au") and 7.24 g/t silver ("Ag") over an average of 13.4 metres within a cumulative area of approximately 320,000 square metres. Results for the final 31 RC holes are from six different stockpiles and include up to 15.0 metres grading 0.83% Cu, 0.23 g/t Au and 12.9 g/t Ag and 22.9 metres grading 0.39% Cu, 0.26 g/t Au and 5.0 g/t Ag. The North stockpile offers the highest grade material with 0.87% Cu, 0.75 g/t Au, and 10.6 g/t Ag over an average thickness of 16.4 metres within a 400 metre by 200 metre area. Ongoing specific gravity measurements from four of the stockpiles indicate a range from 1.80 to 2.25 g/cc3 and average 1.97 g/cc3. Given these encouraging results, Alder intends to commission a mineral resource estimate for the stockpiles.

A trench located in the Bambana area, which is four kilometres northwest of the Santa Rita pit and one kilometre southwest of two historic diamond drill holes, returned 12.0 metres grading 3.32% Cu, 0.22 g/t Au and 37.55 g/t Ag (13.93 g/t Ag with high grade values cut to 50.0 g/t). This trench is located one kilometre southwest of historic holes from 2010 that returned 0.43% Cu and 6.54 g/t Ag over 42.0 metres, and 0.51% Cu, 0.25 g/t Au and 10.41 g/t Ag over 11.5 metres that had intersected a similarly mineralized and altered intrusive rock. Alder is targeting the source of these mineralized intrusions.

Joseph Arengi, President and Chief Executive Officer said, "These RC drill results go a long way toward demonstrating that the Rosita mine stockpiles contain a significant amount of copper-gold-silver mineralization. Of particular interest is that this material may now be economically significant and, on the basis of current and previous work, the potential to identify additional mineralization is deemed excellent. We are also pleased with the results for our new copper-silver discovery at Bambana, and I applaud the work of our exploration team for so quickly identifying impressive high-grade oxide copper and silver. This mineralization further demonstrates the considerable potential of the Rosita area for additional copper-gold-silver mineralization."

The trench at Bambana strikes northeast, is 175 metres long, and was excavated in an area of deep tropical weathering where small-scale artisanal miners are working many of the area's drainages for placer gold and developing shallow prospect pits and shafts in weathered bedrock. Geologic mapping by Alder geologists indicates that copper-silver-gold mineralization at the Bambana trench is localized in and near a variably saprolitized, phyllically-altered diorite dike, which cuts andesitic volcanics. The discovery is at an early stage and currently the geometry of the mineralization remains uncertain. Current plans are to complete additional trenching, mapping, geochemical surveys and prospecting to further define the extent of this mineralization. An IP/resistivity survey will begin in early March at the Santa Rita and R-13 pits and later be extended to include newly identified mineralization at Bambana.
