Los Andes intersects 353.2 metres grading 0.59% and 66 metres grading 0.95% Copper Equivalent at the Vizcachitas Copper-Molybdenum Project

December 17, 2007

Vancouver, BC – Los Andes Copper Ltd. ("Los Andes", or the "Company", TSX Venture Exchange: LA) announces results from a further five holes of the phase II drilling program at the Vizcachitas Project in Chile. All five holes encountered significant mineralization, the highlights of which include: 353.2 metres grading 0.52% Cu and 0.011% Mo (0.59% CuEq.*) that included 0.71% Cu and 0.012% Mo (0.79% CuEq.*) over 54 metres in hole LAV-91, 403.7 metres grading 0.42% Cu that included 0.70% Cu over 36 metres in hole LAV-90 and 430 metres grading 0.03% Mo that included 0.057% Mo over 104 metres in hole LAV-93.

Highlights from all five holes are listed in the table below. Drill hole location maps and sections can be viewed at the Los Andes website www.losandescopper.com.

 (*Copper equivalent is calculated for Mo values greater than 0.01% using US$1.50/lb Cu and US$10.00/lb Mo according to the formula CuEq% =Cu% + (Mo% x 10.00/1.50) and is not adjusted for metallurgical recoveries or net smelter return which remain uncertain and are assumed to be 100%).

Roger Moss, President and CEO of Los Andes Copper commented as follows: “We are very encouraged by the continued success of the drilling at Vizcachitas, and especially by the higher grade mineralization that we continue to intersect in the southwest portion of the drilled area.”

Discussion of Results

LAV-89 was drilled on Section 1100NE and intersected moderately quartz-sericite altered breccia to 47.1 metres and granodiorite between 47.1 metres and the end of the hole. The zone of higher grade mineralization outlined in LAV-68, LAV-72 and LAV-82, is now extended 100 metres to the northwest by the intersection of 92 metres grading 0.70% Cu and 0.023% Mo (0.85% CuEq.) including 0.88% Cu and 0.021% Mo (1.02% CuEq.) over 38 metres in this hole.

LAV-90 was drilled 200 metres to the northwest of LAV-89 and intersected variably altered andesite to 270 metres followed by weakly altered tonalite and granodiorite to the end of the hole. This hole also intersected a higher grade interval grading 0.70% Cu over 30 metres between 32 and 36 metres.

LAV-91 was drilled on Section 1200NE and intersected mostly granodiorite with weak quartz-sericite alteration overprinting weak biotite alteration. The hole was well mineralized along its entire length and also intersected a higher grade interval grading 0.71% Cu and 0.012% Mo (0.79% CuEq.*) over 54 metres.

LAV-92 was drilled on Section 900NE and intersected granodiorite to 81.45 metres followed by alternating diorite and andesite to the end of the hole.

LAV-93 was drilled on Section 1300NE and intersected andesite to 236 metres followed by alternating granodiorite and tonalite with another andesite interval between 294 and 356 metres. This hole also produced one of the best molybdenum intersections so far in the recent drilling programs grading 0.057% Mo over 104 metres.

Roger Moss, Ph.D., P.Geo, is the qualified person as defined by National Instrument 43-101 for the Vizcachitas Project. Logging, sampling and splitting of the drill core is conducted at the Vizcachitas site by independent consultants Geologica LTDA. under the direct supervision of geologist Ramon Fam. Samples are securely transported by Geologica staff to the SGS Laboratory in Santiago Chile and analyzed for copper and molybdenum by atomic absorption following a three acid digestion. Dr. Moss and Mr. Fam have visited the laboratory and are satisfied that the sample preparation and analytical procedure is consistent with standard industry practice. Los Andes routinely inserts standards, duplicates and blanks into the sample stream and sends 5% of sample rejects to Actlabs for check analysis.

About Vizcachitas

The Vizcachitas Project offers potential for a low strip, open pit operation in an area of low elevation with excellent infrastructure, including water and power in central Chile. The Vizcachitas deposit occurs in the same metallogenic belt as the large copper-molybdenum porphyries Rio Blanco-Los Bronces, Los Pelambres-El Pachon and El Teniente. Based on 68 drill holes previously completed by General Minerals Corporation and Placer Dome, the project contains an indicated resource of 232 million tonnes grading 0.46% copper and 0.014% molybdenum and an inferred resource of 619 million tonnes grading 0.38% copper and 0.013% molybdenum at a 0.30% copper cutoff.  At a 0.4% cutoff, indicated resources total 144 million tonnes grading 0.52% copper and 0.015% molybdenum and inferred resources total 211 million tonnes grading 0.46% copper and 0.016% molybdenum as detailed in the NI43-101 compliant technical report of A.C.A. Howe International Limited dated February 7, 2007. The technical report, as well as additional information about the Vizcachitas Project is available on our website at www.losandescopper.com.
