Andean Intersects 31m of 52.1 g/t Gold and 568 g/t Silver in a Deep Geotechnical Hole at Cerro Negro

FREMANTLE, WESTERN AUSTRALIA--(Marketwire - Dec. 18, 2008) - Andean Resources (TSX:AND)(ASX:AND) reports the second set of results from its recently commenced 2008/09 drill program at its 100% owned Cerro Negro project in Southern Argentina including the following highlights:

- EDD-887, drilled more than 50m below the base of the current Eureka West Resource intersects 31m of 52.1 g/t gold and 568 g/t silver

- Contour exploration (incremental step-outs) continue to extend mineralization at Eureka West

- Infill drilling at Eureka West continues to confirm structural and grade continuity, supportive of further upgrading of inferred resources

- Eureka West remains open at depth and to the west

All 10 holes reported in this release were drilled into the Eureka West veins. 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 Eureka for all the interval summaries reported in this release.

Eureka West Vein - Step-out Holes

Andean continues to drill test the high-grade Eureka West Vein in order to better define the top and bottom limits of the structure which hosts the Eureka West mineral resource. The highlights of the recent drill results include:

- EDD-887: 31m of 52.1 g/t Au and 568 g/t Ag from 334m

Including: 23.7 m of 65.1 g/t Au and 712 g/t Ag from 334m

- ERC-889: 2m of 11.4 g/t Au and 185 g/t Ag from 212m and

12m of 6.1 g/t Au and 87 g/t Ag from 218m

Including: 6m of 8.2 g/t Au and 110 g/t Ag from 218m

- ERC-890: 1m of 44.0 g/t Au and 53 g/t Ag from 194m

- ERC-891: 6m of 20.8 g/t Au and 105 g/t Ag from 5m

- ERC-893: 5m of 7.5 g/t Au and 159 g/t Ag from 131m and

16m of 5.6 g/t Au and 69 g/t Ag from 165m

- ERC-895: 7m of 12.8 g/t Au and 258 g/t Ag from 289m

EDD-887 was drilled as a geotechnical hole to test rock quality in the hanging wall andesite ahead of designing the underground decline. The Eureka West vein was intersected at the 300m elevation, the deepest drill intersection on the vein to date, and returned the 31m high-grade intersection in the 1.0 split. This same hole then encountered a 6m intersection of 6.0 g/t Au and 99 g/t Ag corresponding to the 1.1 split. Since this was a geotechnical hole, the intersection was oblique to the vein (see the attached cross-section), and the estimated true thickness of the intersection is about 6m.

EDD-889: The hole tests the up-dip extent of both splits. The 1.0 split here is eroded, and the two intersections of 2m of 11.4 g/t Au 185 g/t Ag and 12m intersection of 6.1 g/t Au and 87 g/t Ag corresponds to the 1.1 split.

ERC-890: This hole tests the upper limit of the vein below the La Matilde Formation with intersections of 1m of 44.0 g/t Au and 53 g/t Ag in the hanging wall and 5m of 3.0 g/t Au and 37 g/t Ag in the footwall.

ERC-891: Shallow hole testing the upper limit of the vein beneath the Eureka West vein (1.0 split) outcrop which assayed 6m of 20.8 g/t Au and 105 g/t Ag.

ERC-893: Tests the upper part of the vein beneath the La Matilde Formation. The first intersection (5m of 7.5 g/t Au and 159 g/t Ag) is the 1.0 split, probably partly eroded and the second intersection (16m of 5.6 g/t Au and 69 g/t Ag) is the 1.1 split.

ERC-895: Up-dip hole which intersects near the old paleo-surface, with 7m of 12.8 g/t Au and 258 g/t Ag, and may not add materially to the resource.

Eureka West Vein - Infill Holes

Several new and encouraging infill holes have been drilled aimed at upgrading the inferred resource at the Eureka West veins of 336,000 oz of gold into the indicated status. The results were as follows:

ERC-888: 17m of 14.1 g/t Au and 372 g/t Ag from 136m

ERC-892: 5m of 8.5 g/t Au and 33 g/t Ag from 229m and

3m of 9.9 g/t Au and 110 g/t Ag from 243m

EDD-896: 12.3m of 8.9 g/t Au and 116 g/t Ag from 172.7m

Including: 6m of 14.0 g/t Au and 153 g/t Ag from 177m

ERC-897: 15m of 6.1 g/t Au and 40 g/t Ag from 186m

Including: 4m of 9.4 g/t Au and 63 g/t Ag from 192m

These results appear to support an upgrading of the inferred resource and are shown on the Longitudinal Section presented in this release.

Wayne Hubert, Andean's CEO, summarized, "Our deepest hole on the project, EDD-887 intersects the Eureka West vein with a true width of about 6m and grades of almost 2 ounces per ton of gold and 18 ounces per ton of silver showing the vein is open to depth in an area of no previous drilling. This rock is worth almost $2000 per ton at today's prices. The third rig we have just brought in will allow us to immediately begin extending the resource to depth."

Next Steps

Andean's 2008/09 programs continue to progress ahead of schedule with approximately 40 further holes having been drilled and awaiting assays.

In addition to the previously mentioned infill holes, three deep drill-holes have been drilled into the Eureka SE extension searching for the next ore shoot. Several holes have also been drilled to test a potential connection between the 721 vein and the Evita vein. Andean will continue to update the market in the New Year as these results become available.

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 and assayed by ACME Analytical Laboratories SA (Mendoza) in Mendoza, Argentina.

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.
