ALR

Alder Resources Ltd. ("Alder" or the "Company") (TSX VENTURE:ALR) is pleased to
provide exploration highlights for the Rosita Project in northeast Nicaragua.
The following highlights were achieved during its first year of exploration over
the 33.57 km2 Rosita D Concession (Figure 1): 




--  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;

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

--  Discovery of a new gold zone at El Rastro with samples returning up to
    114.12 g/t Au;

--  Confirmation of porphyry Cu +-Au, Ag mineralization with historic
    intercepts that returned 0.43% Cu and 6.54 g/t Ag over 48.0 metres and
    0.51% Cu and 0.25 g/t Au over 11.5 metres; and

--  Identification of four large geophysical anomalies that are deemed to be
    highly prospective Cu-Au-Ag porphyry targets at Bambana.



Company President and CEO, Joseph Arengi, states: "With minimal work and in a
very short time, Alder has discovered and documented numerous zones of copper,
gold and silver mineralization on the Rosita property that, in management's
opinion, indicate that the Rosita property encompasses a major mineralized
system. With our current stockpile mineral resource in hand we are confident
that with additional drilling Alder can delineate a better than average grade
deposit on the Rosita Property".


Since October 2011 Alder has carried out an aggressive exploration program that
has included reverse circulation and diamond drilling, ground geophysical
surveys, resource delineation, soil sampling and trenching. 


Mineral Resource Estimate

Alder completed a 1,575 metre reverse circulation drill program with the primary
objective to evaluate mineralization contained in a series of stockpiles which
flank the historic Santa Rita pit. A National Instrument 43-101-compliant
inferred mineral resource estimate for the stockpiles totals: 7.95 million
tonnes averaging 0.62% copper ("Cu"), 0.46 grams per tonne ("g/t") gold ("Au")
and 9.21 g/t silver ("Ag") (see news release dated May 9, 2012), based on a
0.15% copper equivalent cut-off, which equates to 108.5 million pounds copper,
118,500 ounces gold and 2.35 million ounces silver. 


Santa Rita/R-13 Skarn Mineralization

The company also completed an 18 hole, 5,485 metre core drilling program in the
vicinity of the past producing Santa Rita and R-13 open pits. The drilling was
designed to test historic Cu-Au-Ag mineralized intercepts, obtain basic geologic
information and to identify areas where mineralized tonnage could be developed
and complement the stockpile resource that would increase potential commercial
viability. Drill hole locations are shown in Figure 2. Significant assay results
for the core drilling program at Santa Rita as well as Bambana are summarized in
Table 1 below:

NB. Thickness represents drilled width; true widths are unknown at this time.
CuEq = Cu% + Au g/t x (0.6033) + Ag g/t x (0.012) and US$2.90/lb Cu, US$1200/oz
Au and US$24/oz Ag. Values are not top cut. Na = not applicable.


At Santa Rita a corridor of Cu-Au-Ag skarn mineralization has been identified in
a series of stacked lenses over a 1,100 metre strike length that is open along
strike and down dip (Figure 2). Additional, closer spaced drilling will be
carried out along the Rosita corridor with the goal of defining an in situ
mineral resource that will complement the stockpile resource.


Gold Discovery at Santa Rita returns 29.54 g/t Au over 8.0 metres

In addition to the skarn mineralization, a later, Au-rich mineralizing event
that over prints and transects the skarn mineralization along the western end of
the Santa Rita pit has been interpreted along a northwest trending zone. Hole
D914 intersected this zone and returned 8.0 metres grading 29.54 g/t Au. The
zone was also intersected in two gold intercepts in each of holes D910 (8 metres
at 6.90 g/t and 15 metres at 1.52 g/t) and D912 (2 metres at 1.45 g/t and 4
metres at 1.76 g/t), located 250 metres to the southeast. The zone is open along
strike and down dip and is coincident with a strong northwest trending IP
chargeability anomaly (Figure 2).


Bambana Porphyry Targets

Exploration at Bambana focused on the T3 Zone, an area of exotic Cu-oxide
mineralization four kilometres northwest of the Santa Rita pit (Figure 2).
Trenching returned 12.0 metres grading 3.32% Cu, 0.22 g/t Au and 37.55 g/t Ag.
Rock chip sampling returned two wide intercepts of 2.09% Cu, 0.19 g/t Au and
14.6 g/t Ag over 29 metres and 1.98% Cu, 0.14 g/t Au and 14.4 g/t Ag over 29.0
metres. Two diamond drill holes tested the Cu-oxide mineralization and returned
13 metres grading 1.23% Cu, 0.36 g/t Au and 10.63 g/t Ag in hole D919 and 18
metres grading 1.74% Cu, 0.09 g/t Au and 16.65 g/t Ag in hole D920. In both
holes mineralization begins at surface. The T3 Zone occurs along the flank of a
strong IP chargeability anomaly. Additional exploration in this area will be
carried out to determine the extent of this mineralization. 


Exploration was also carried out at a highly prospective porphyry target,
Tipispan, one kilometre northeast of T3. Two diamond drill holes were completed
by Calibre Mining in 2010 to test for continuity in Cu-oxide mineralization in a
small, well mineralized pit (Figure 3). Sampling by Alder returned 6.28% Cu,
0.74 g/t Au and 132.75 g/t Ag over 2.8 metres. One hole drilled to the southwest
intersected porphyry-style copper mineralization in a potassically altered
intrusive that returned 0.43% Cu and 6.54 g/t Ag over 48.0 metres at a vertical
depth of 100 metres. A second hole drilled to the northeast, returned 11.5
metres grading 0.51% Cu and 0.25 g/t Au in a highly altered diorite intrusive.
The mineralized intercepts in these holes have not been followed up and the zone
is open in all directions. Recently excavated Trench 10 is 40 metres northwest
and along strike from the prospect pit. Cu-oxides over narrow widths within a
broad zone of altered intrusive with quartz veining, have been reported. Assay
results for the trench are pending.


In addition to the targets discussed above, the IP geophysical survey identified
a series of strong chargeability anomalies that conform to a circular feature
interpreted from a magnetic survey (Figure 3). Chargeability anomalies are
inferred to represent areas of disseminated sulphide mineralization that could
represent porphyry-type exploration targets. In addition to the anomaly at T3,
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 historic
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. Geologic
mapping, trenching and soil sampling have been carried out over Zopilote. 


(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.


El Rastro discovery returns samples to 114.12 g/t Au 

Alder is currently carrying out a detailed mapping, soil sampling and trenching
program at Rosita. Rock chip sampling has returned up to 114.12 g/t Au at El
Rastro.


Ongoing Exploration

In addition to the well mineralized sample from El Rastro, several other rock
samples returned gold values greater than 1.0 g/t, mainly in the Bambana area. 


Soil sampling has identified coincident Cu and Au anomalies along a one
kilometre long northwest trend north of El Rastro as well as several broad 400
metre wide +300 ppm Cu anomalies at T3, Tipispan, Zopilote and El Rastro South. 


Eleven hand-dug trenches have been excavated, nine at Bambana and two at El
Rastro. Results are summarized in Table 3 below.

Mineralogical Analysis

As a precursor to a metallurgical testing of the stockpile material, four
composite samples from mineralized reverse circulation drill cuttings were
evaluated for deportment of copper, gold, silver and zinc. Results indicate that
copper occurs mainly as chalcopyrite and covellite and has a predicted flotation
recovery of 72% to 75%. Gold occurs in native form as well as electrum and has a
predicted recovery by flotation of 72%. Silver occurs mainly as solid solution
in covellite and chalcocite with lesser amounts in chalcopyrite and has a
predicted flotation recovery of 62%. It may be possible to improve the predicted
recoveries with finer grinding and detailed metallurgical testing.


Proposed Activities

Future program goals include delineating the geometry, orientation, limits, and
controls for the mineralization identified during Phase 1. Specific objectives
include:


1. In-fill drilling along the south side of the Santa Rita/R-13 area with a goal
to define mineral resources. 


2. Continued exploration for additional high grade gold mineralization along the
northwest-striking structural corridors.


3. Prioritize and selectively test IP chargeability anomalies identified over
the property to evaluate the potential for new porphyry style Cu-Au
mineralization.


4. Drill test to expand the Cu-Au-Ag porphyry style mineralization encountered
in previous drilling in the Bambana area. 


Quality Assurance/Quality Control

Reverse circulation drill samples were collected into heavy gauge plastic bags,
sealed on-site, then stored at Alder's secure Rosita field office. All diamond
drill holes were collared using HQ-size drill core, and reduced to NQ-size where
necessary. Core was loaded on-site into wooden core boxes and transported on a
daily basis by Company personnel to Alder's field office where geologists logged
the holes and selected intervals for assay. Individual samples of drill core
were sawed, using a 10" diamond blade trim saw. Half of the sample was retained
in the core box, the rest loaded into a pre-numbered, heavy gauge plastic bag
and sealed. All samples were transported on a weekly basis (by the laboratory or
by Company personnel) to Inspectorate Exploration and Mining Services'
preparation laboratory in Managua. There, pulps were prepared for shipping to
Inspectorate's Analytical laboratory in Vancouver, where each sample was
analyzed via fire assay for gold and for copper, silver and 28 other elements
using ICP (Inductively Coupled Plasma-atomic emission spectrometry) methods.
Alder has implemented an industry standard Quality Assurance/Quality Control
program that includes the insertion of certified standards and blanks into the
sample stream.
