We present the results of a 3-year long , medium-resolution spectroscopic campaign aimed at identifying very metal-poor stars from candidates selected with the CaHK , metallicity-sensitive Pristine survey .
The catalogue consists of a total of 1007 stars , and includes 146 rediscoveries of metal-poor stars already presented in previous surveys , 707 new very metal-poor stars with [ Fe / H ] < -2.0 , and 95 new extremely metal-poor stars with [ Fe / H ] < -3.0 .
We provide a spectroscopic [ Fe/H ] for every star in the catalogue , and [ C/Fe ] measurements for a subset of the stars ( 10 % with [ Fe / H ] < -3 and 24 % with -3 < [ Fe / H ] < -2 ) for which a carbon determination is possible , contingent mainly on the carbon abundance , effective temperature and S/N of the stellar spectra .
We find an average carbon enhancement fraction ( [ C / Fe ] \geq + 0.7 ) of 41 \pm 4 % for stars with -3 < [ Fe / H ] < -2 and 58 \pm 14 % for stars with [ Fe / H ] < -3 , and report updated success rates for the Pristine survey of 56 % and 23 % to recover stars with [ Fe / H ] < -2.5 and [ Fe / H ] < -3 , respectively .
Finally , we discuss the current status of the survey and its preparation for providing targets to upcoming multi-object spectroscopic surveys such as WEAVE .
