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. 


(1)This 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.
