Alder Reports 2.09% Copper, 0.19 g/t Gold, and 14.6 g/t Silver Over 29 Metres and 1.98% Copper, 0.14 g/t Gold and 14.4 g/t Silver Over 29 Metres in Bench Sampling at Bambana Prospect, Nicaragua

Coincident 1,100 Metre by 500 Metre Geophysical Target

TORONTO, ONTARIO--(Marketwire - June 13, 2012) - Alder Resources Ltd. ("Alder" or the "Company") (TSX VENTURE:ALR) is pleased to announce assay results for rock chip sampling at two 1970s era open pit benches at the Bambana prospect, Rosita copper-gold-silver project, northeast Nicaragua (see Figure 1). Channel sampling across the full width of two benches from an open pit along the side of a small hill returned two wide intercepts of 2.09% copper ("Cu"), 0.19 grams per tonne ("g/t") gold ("Au") and 14.6 g/t silver ("Ag") over 29 metres in the upper bench and 1.98% Cu, 0.14 g/t Au and 14.4 g/t Ag over 29.0 metres in the lower bench. The mineralization is of an oxide nature and is open in all directions.

The results presented here are from two of four benches developed on the slopes of a small hill during the final stages of mining operations in the Rosita area during the 1970s. The benches were developed over approximately 20 metres vertically and along a strike length of 40 metres. These results complement those from a nearby trench excavated by Alder and reported previously (see news release dated March 1, 2012), that returned 3.32% Cu, 0.22 g/t Au and 37.55 g/t Ag over 12.0 metres. The trench is 30 metres west of the upper bench, and collectively these workings, referred to as the T3 Zone, occur over a strike length of 70 metres. Continuous 1 metre samples were collected across the full width of the open cut benches. Each of the two sample traverse lines ended in material grading between 0.8% and 1.2% copper. The mineralization, consisting of malachite, chrysocolla, and other copper oxides, is localized in a fine-grained, sericite-altered diorite porphyry dike which strikes generally east cutting propylitically-altered andesitic volcanic rocks.

The T3 Zone lies within a broad, discreet IP chargeability anomaly that is 1100 metres long by 500 metres wide at the -100 metre level (see Figure 2). This anomaly is attributed to the presence at depth of disseminated sulphides, which may be related to porphyry style mineralization, and represents significant potential for Alder to add to the Cu-Au-Ag resource delineated at the Santa Rita stockpiles earlier this year (see news release dated May 9, 2012).

In addition to the T3 Zone, several discreet IP chargeability anomalies at the -100 metre level have been delineated at Bambana and are under investigation. Chargeability anomalies are inferred to represent areas of disseminated sulphide mineralization that could represent porphyry-type exploration targets. An 800 metre by 500 metre anomaly occurs in the north central part of the Bambana area and an approximate 1,500 metre by 1,000 metre anomaly has been delineated in the southeast corner of the Bambana area. The latter coincides with the Zopilote prospect, drilled in the 1960s, with reported reserves of 176,000 tonnes of oxide material grading 0.90% Cu and 79,000 tonnes of sulphide material grading 0.97% Cu (referenced in a map by A. Rivera, 1977)1. Gold and silver values are not reported for this zone. A ground magnetometer survey, geologic mapping, trenching and general prospecting will be carried out over these anomalies followed by drill testing in the 3rd quarter of 2012.

1This historical estimate was not prepared in accordance with currently accepted guidelines for the preparation of mineral resources and mineral reserves, does not comply with NI 43-101 and should not be relied upon. Although the historical estimate is relevant to recognizing potential, a qualified person, as such term is defined in NI 43-101, has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves and the Company is not treating the historical estimate as current mineral resources or mineral reserves.

Alder President and CEO, Joe Arengi, states: "Given the consistent high copper grades and the oxide nature of the mineralization at the T3 Zone, we are highly encouraged by the bench sampling program, and look forward to drill testing these anomalies in the coming months. Two of the three large-scale, deposit size geophysical anomalies delineated at Bambana by our recent survey coincide with good grade copper mineralization and provide Alder with compelling upside. These results further fuel our initial optimism about the Rosita project, which was based primarily on the immediate area surrounding the past producing Santa Rita and R-13 zones. Now Alder has four significant target areas, three of them with porphyry style attributes, within the Rosita concession block that reinforces the Company's goal of developing an economic mineral deposit at Rosita."

To date a total of 5,025 metres have been drilled in 16 holes, all in the Santa Rita/R-13 area. Assay results have been reported for the first 3,144 metres in 9 holes of an 8,000 metre drill program for the Rosita project (see news release of May 31, 2012). The initial 5,000 metre campaign was centered on the historic Santa Rita and R-13 pits, where approximately 5.5 million tonnes of ore averaging 2.06% Cu, 0.93 g/t Au, and 15 g/t Ag were extracted by La Luz Mines (a subsidiary of Falconbridge) in the mid-1970s when low metal prices forced mine closure. An additional 3,000 metres will be drilled at Bambana and other targets generated during the exploration program. In addition, an IP-resistivity geophysical survey has been completed at Bambana and several distinct chargeability anomalies have been delineated. The survey will now focus on the Santa Rita/R-13 area with completion expected in early July.

The Rosita Project

The Rosita project is located seven kilometres north of the Primavera prospect, where Calibre Mining Corp. ("Calibre") and B2Gold Corp. announced the discovery of significant porphyry style Au-Cu mineralization, including 261.7 metres grading 0.78 g/t Au and 0.30% Cu in a diamond drill hole (Calibre news release dated January 20, 2012).

In a news release dated May 9, 2012 Alder announced an independent NI 43-101-compliant inferred resource estimate for the stockpiles at Rosita. The resource estimate totals 108.5 million pounds Cu, 118,500 ounces ("oz") Au and 2.35 million oz Ag contained within 7.95 million tonnes based on a cutoff of 0.15% copper equivalent, and averages 0.62% Cu, 0.46 g/t Au and 9.21 g/t Ag.

Quality Assurance/Quality Control

Bench panel samples were collected from fresh surfaces along the face of both benches at continuous one metre intervals. Samples were placed into a heavy gauge plastic bag, sealed then trucked (by the lab or by company personnel) to Inspectorate Exploration and Mining Services' preparation laboratory in Managua. There, pulps are prepared for shipping to Inspectorate's Analytical laboratory in Vancouver, where each sample is analyzed for total copper using aqua regia digestion and a 30 element ICP (inductively coupled plasma-atomic emission spectrometry) method, and gold using fire assay with AA finish. Alder has implemented an industry standard Quality Assurance/Quality Control program that includes the insertion of certified standards and blanks into the sample stream.
