We report abundance analyses results for three stars whose velocities in the galactic rest frame exceed 400 km s-1. We have found the following [Fe/H] results: CD 29°2277 (-1.63); HD 134439 (-1.57); G64-12 (-3.52). is the most metal-deficient star analyzed to date. We have also obtained other elemental abundances, including [Al/Mg], and we discuss the results of these and other extreme velocity stars whose origins probably lie in the distant galactic halo.
