Andean Intersects 32m of 34.6 g/t Gold and 214 g/t Silver With a 50m Stepout | ||||
PERTH, AUSTRALIA--(Marketwire - Jan. 27, 2009) - Andean Resources (TSX:AND)(ASX:AND) reports the next set of results from its ongoing 2008/09 drill program at its 100% owned Cerro Negro project in Southern Argentina. Today's results include the following highlights: - EDD-901 drilled 50m to the west of EDD-887 (31m of 52.1 g/t Au and 568 g/t Ag) at a similar depth and intersected 32m of 34.6m Au and 214 g/t Ag on the Eureka West veins - 721 Vein extended along strike with high grades, including ERC-8135, which intersected 4m of 49.6 g/t Au and 667 g/t Ag - New high-grade zone intersected in the Eureka Main vein including ERC-8125 with 4m of 32.0 g/t Au and 844 g/t Ag - Deep step-out drilling continues at Eureka West 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 Veins - Step-out Holes The following four drill-holes represent the most significant step-out holes drilled beyond the existing high-grade resource blocks, which define the current Mineral Resource at Eureka West. EDD-901: 32m of 34.6 g/t Au and 214 g/t Ag from 340m Including: 17.6m of 41.5 g/t Au and 335 g/t Ag from 340m and 1.0m of 327.1 g/t Au and 413 g/t Ag from 364m EDD-8110: 11.3m of 10.2 g/t Au and 252 g/t Ag from 216m Including: 1.7m of 41.5 g/t Au and 602 g/t Ag from 223m EDD-8118: 10m of 17.7 g/t Au and 231 g/t Ag from 243m Including: 5m of 27.7 g/t Au and 331 g/t Ag from 248m EDD-8126: 8m of 8.1 g/t Au and 61 g/t Ag from 381m Including: 1m of 25.9 g/t Au and 211 g/t Ag from 381m EDD-8110 and EDD-8118 were drilled on the same section (200E) below previous drilling and updip from EDD-887. See attached cross-section of 200E. EDD-8126 was drilled on the most westerly section (150W) where the Eureka West veins have been intersected, and about 50m beneath the previous drilling. See the attached long-section showing the intersection at the 350m asl. 721 Vein - Extension Drilling Several new holes have been drilled into the 721 Vein, which lies en-echelon from the Eureka West veins. These latest results appear to have connected it to the previously announced Evita Vein and have extended the high-grade ore shoot comprising the 721 Vein to the east: ERC-8131: 11m of 17.4 g/t Au and 33 g/t Ag from 168m Including: 2m of 41.6 g/t Au and 56 g/t Ag from 171m and 3m of 25.7 g/t Au and 72 g/t Ag from 175m ERC-8135: 4m of 49.6 g/t Au and 667 g/t Ag from 265m Eureka Main Vein - Extension Drilling The Eureka Main Vein lies approximately 150m to the north of the 721 Vein, and to date has received limited drilling. Several new holes have been drilled into the Eureka Main vein to further delineate the ore-shoot previously defined west of the Canadon del Puma and were successful in intersecting additional high-grades including: ERC-8119: 2m of 12.8 g/t Au and 32 g/t Ag from 217m ERC-8125: 4m of 9.4 g/t Au and 262 g/t Ag from 141m and 4m of 32.0 g/t Au and 844 g/t Ag from 157m ERC-8127: 13m of 3.7 g/t Au and 183 g/t Ag from 135m ERC-8129: 3m of 20.2 g/t Au and 150 g/t Ag from 151m EDD-8140: 6m of 8.9 g/t Au and 61 g/t Ag from 209m - ERC-8125 - above 8m of 6.9 g/t Au, 159 g/t Ag in EDD-834 - ERC-8129 - above EDD-712; which intersected no significant values As shown on the longitudinal section, the Main Vein ore shoot remains open both up- and down-plunge. Again, the mineralization defined at the Eureka Main Vein is not included in the April 2008 Mineral Resource, but will be included in the resource for all the Eureka veins being prepared for the June quarter of this year. Wayne Hubert, Andean's CEO, summarized, "Overall, the Eureka area at Cerro Negro is proving to be a world class epithermal system with bonanza grades now becoming common in three of the known veins, only one of which, the Eureka West vein, currently has gold and silver resources attributable to it. These extraordinary mineralized widths and high grades are expected to significantly improve the updated Eureka resource and extend the high-grades in the mine-life, which will again improve the already robust project economics." Next Steps Andean's 2008/09 exploration programs continue to progress ahead of schedule. Three drills are on the property exploring the Eureka West veins to depth, extending the 721 vein, and drill-testing areas for the Bankable Feasibility Study.

are drilled widths, not true widths. True widths are less than drilled intersections and can be determined from the Eureka cross- sections provided (2) Some coordinates and elevations are approximate and subject to final survey by a licensed surveyor 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.
