Andean Resources Expands Bajo Negro Discovery and Provides Additional Disclosure

FREMANTLE, WESTERN AUSTRALIA, Jul 07 (MARKET WIRE) --
Andean Resources Ltd. (TSX: AND)(ASX: AND) is pleased to report six
additional diamond drill results from the recent Bajo Negro discovery at
its 100% owned Cerro Negro gold and silver project in Southern Argentina.
These latest results continue to provide new resource potential at the
project and highlights include:

- BDD-914 intersected 3.5m of 26.7 g/t Au and 58 g/t Ag from 242m

- BDD-915 intersected 5.25m of 18.7 g/t Au and 27 g/t Ag from 202m

- BDD-918 intersected 7m of 10.3 g/t Au and 20 g/t Ag from 121m

- Strike length of the vein has now been tested along approximately 550
meters

- Mineralization remains open at depth

- To date, all 19 drill holes in Bajo Negro have intersected
mineralization with grades exceeding 2.5 g/t Au over mineable widths

Reported widths are intersected widths, and true widths are less in every
case (see Table 1 for detailed drill data). Andean has assumed an
underground cut-off grade of 2.5 g/t gold at Bajo Negro for all the
interval summaries reported in this release.

Bajo Negro Vein

The confirmation of the Bajo Negro vein discovery, located 13 kilometres
east of the Eureka West veins and 2 kilometres southwest of the Vein Zone
deposit, was announced on May 19, 2009. The nineteen holes for which
results have been received all intersected the Bajo Negro vein with
widths and grades which could permit underground mining. Potentially
mineable widths and grades can now be inferred over a strike length of at
least 550m and vertical extent of 150m.

The following new intersections, taken in conjunction with
previously-announced results, define the upper part of an ore shoot which
is open to depth and along strike:

BDD-914: 3.5m of 26.5 g/t Au and 58 g/t Ag from 242m

BDD-915: 3.35m of 6.9 g/t Au and 14 g/t Ag from 193m
And 5.25m of 18.7 g/t Au and 27 g/t Ag from 202m

BDD-916: 9.85m of 6.6 g/t Au and 11 g/t Ag from 136m
And 3.3m of 8.9 g/t Au and 30 g/t Ag from 152m

BDD-917: 2.8m of 10.7 g/t Au and 70 g/t Ag from 101m

BDD-918: 11.1m of 7.6 g/t Au and 14 g/t Ag from 119m
Including 7m of 10.3 g/t Au and 20 g/t Ag from 121m

BDD-919: 10.2m of 5.2 g/t Au and 7 g/t Ag from 231m

Each of these new drill holes, together with the previous drill holes,
is shown on the longitudinal section, Figure 2. Hole BDD-914 is the
deepest hole for which results have so far been received, with an
intersection at about 660m elevation, or 240m below the surface. The hole
intersected the vein approximately 50m below the intersection in BRC-913
(7.75m, 38.9 g/t Au, 45 g/t Ag). The intersection in BDD-914, although
narrower than most, shows the persistence of high gold grades with depth.

BDD-915 was drilled 150m southeast of BDD-914 and cut the Bajo Negro vein
about 40m below the high-grade intersection in BRC-911 (7m of 60.7 g/t
Au, 90 g/t Ag). BDD-915 demonstrates that gold grades and widths above 50
gram-meters persist at depth.

BDD-916 and BDD-917 were drilled on the same section 100m southeast of
BDD-915. The holes intersected the vein in the upper part of the shoot,
and grade-thickness contours suggest that values will improve with depth.

BDD-918 and BDD-919, also drilled on the same section, are the most
southeasterly holes drilled into the Bajo Negro vein to date. They show
that the shoot is still open to the southeast, with values above 50
gram-meters. The holes show that the quartz vein, dipping 70 degrees NE,
continues to be strongly developed towards the southeast, with a true
width of 7-8m.

In summary, the latest holes have outlined the southeastern part of a
high-grade (greater than 100 gram. meters gold) ore shoot surrounded by
mineralization greater than 50 gram-meters, which remains open along
strike and to depth. The top of the mineralization (as defined by the 5
gram meter contour) occurs at 50 to 100m depth, and is likely to have
been influenced by the paleowater table.

Encouragingly, this would suggest that the hydrothermal system is intact
and has undergone little or no erosion. Barren silicified outcrops, 150m
northwest of current drilling (see Figure 1), are interpreted as remnants
of a silica cap deposited above the paleowater table. Aeromagnetic
lineaments (Figure 1) suggest that continuation of the vein below these
outcrops is a strong possibility.

Currently, two core drill rigs are focused on extending Bajo Negro
along strike and at depth, and updates will be provided on a regular
basis.

Quality Control and Assurance

The analytical results quoted in this release are derived from half drill
core in the case of diamond drill holes, or from cuttings in the case of
reverse circulation holes. Samples are prepared by ACME Analytical
Laboratories SA (Mendoza) in Mendoza, Argentina, and assayed by the same
laboratory in Santiago, Chile. Gold is determined initially by fire assay
with AA finish. Samples assaying more than 10 ppm gold are re-assayed
using a gravimetric finish. Silver is determined initially by AAS, and
samples assaying more than 100 ppm silver are re-assayed by fire assay
with gravimetric finish. Quality control of the analytical results is
maintained by inserting standards, blanks, and duplicates into the sample
run, approximately every twenty samples. Additional quality control is
maintained by sending assay sample splits to a second laboratory from
time to time. These checks are evaluated statistically at regular
intervals. All analytical data are entered into a Microsoft Access
database, with limited access and numerous checks to ensure integrity of
the data.

Note: The information in this Report that relates to exploration results
is based on information provided by David Shatwell who is a Fellow of the
Australian Institute of Geoscientists. Mr. Shatwell has extensive
experience relevant to the style and type of mineralisation and deposits
under consideration, and to the activity undertaken, to qualify as a
Competent Person as defined in the 2004 Edition of the "Australian Code
for Reporting of Mineral Resources and Ore Reserves" (the JORC Code). Mr.
Shatwell consents to the inclusion in this Report on his work in the form
and context in which it appears.

Additional Disclosure

In connection with the filing of the prospectus for Andean's recently
announced $90 million bought-deal financing, the Company has been
requested to clarify certain of its recently published disclosure on the
Company's website at www.andean.com.au and in material distributed
through press releases, relating to the Cerro Negro project, located in
Southern Argentina.

Certain of the Company's previously filed continuous disclosure documents
did not include the grade information for each category of mineral
resource and reserves. In particular, the information contained in the
press releases of the Company dated January 30, 2009 and April 30, 2009,
which disclosed gold and silver resource and reserve estimates, should
have disclosed the grade and quantity for each category. The following
tables set out the revised information:
