Alder sampling returns 4.46% copper, 10.84 G/T gold and 97.4 G/T silver at Rosita project, Northeast Nicaragua

Alder Resources Ltd. ("Alder" or the "Company") (TSX VENTURE:ALR) is pleased to provide results from a series of grab samples from two areas at the Tipispan porphyry copper-gold prospect within the Company's Rosita Project in northeast Nicaragua (Figure 1).
All of the samples were collected from artisanal miner workings located within two areas that are 50 metres apart and 250 metres southwest of high grade trench results that included 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 previously reported in a news release dated January 9, 2013 (Figure 2). Complete results for the grab samples are provided in Table 1 at the end of this news release.
Company President and CEO, Joseph Arengi, states: "Our exploration team continues to locate well mineralized zones in the highly prospective Tipispan area and we are very encouraged by the results. We will continue our sampling and trenching program in this area in an effort to better understand the controls on mineralization. The location of these samples relative to the high grade trench results significantly expands the footprint of porphyry style mineralization at Tipispan."
The host rock for all of the mineralized samples is granite with local potassic alteration and stockwork veining. In places the granite is being replaced by sulfides, including chalcopyrite, bornite, sphalerite, galena, pyrite and chalcocite, and oxides that include malachite, chrysocolla and azurite.
The Tipispan prospect is located within the Bambana area which is four kilometres northwest of the past producing Santa Rita pit and one kilometre northeast of the T3 zone (Figure 1) where trenching has returned up to 3.32% Cu, 0.22 g/t Au and 37.55 g/t Ag over 12.0 metres and drilling has returned up to 1.74% Cu and 16.64 g/t Ag over 18.0 metres in an exotic copper-oxide zone.
