Popis:	An experimental search of distinctive signals of WIMPs is underway at the Sierra Grande mine (∼ 1000 m.w.e.) in Argentina with a natural germanium detector. The site and the experimental set-up are described. The results corresponding to an exposure of 302.4 kg day are presented in the customary form of σ(m) exclusion plots. The region in the WIMP-Ge cross-section versus WIMP mass plane ruled out by this experiment for heavy, non-relativistic neutrino-like Dirac particles scattering coherently off Ge nuclei through vector weak interactions corresponds to masses from 12 GeV up to about 1.7 TeV. The data taking is in progress with the purpose of looking for possible daily modulation effects in the Southern Hemisphere.
