We have analyzed the RAVE spectra of 543 candidate very metal-poor (VMP) stars, the large majority of which have not been identified as such to date. These stars are relatively bright, with the mean V magnitude of the candidates being 11.5. The quality of the RAVE spectra are high enough to measure the metallicity of these stars to better than 0.3 dex uncertainty when calibrated by high-resolution spectroscopy. Of these candidates, we have found 447 stars with [Fe/H] < -2, 16 stars with [Fe/H] < -3, and 1 star with [Fe/H] < -4. In addition, we have obtained 108 high-resolution, high-S/N spectra of these stars and have analyzed them for their detailed elemental abundances, including n-capture species. We have found new C-rich stars, s-process enhanced stars, r-process enhanced stars, Li-rich giants, etc. This sample is an excellent laboratory for the understanding of the early chemical enrichment history of the Milky Way.
