We introduce the The Hobby-Eberly Telescope Chemical Abundances of Stars in the Halo (CASH) Project. This University of Texas Long Term Project aims at discovering metal-poor Galactic halo stars selected from various surveys. We present the results of the first year of HET observations: Thus far, 200 objects are observed with the high-resolution spectrograph. Data reduction and stellar parameter determination, as well as our automated analysis procedure are described. A handful of stars with [Fe/H]<-3.0 were found. We also report an individual abundance analysis of three metal-poor program stars that confirm our automated analysis techniques.
