We present the results of a 3-yr long, medium-resolution spectroscopic campaign aimed at identifying very metal -poor stars from candidates selected with the CaHK, metallicitysensitive 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 per cent with [Fe/H] < -3 and 24 per cent with -3 < [Fe/H] < -2) for which a carbon determination is possible, contingent mainly on the carbon abundance, effective temperature and signal-to-noise ratio of the stellar spectra. We find an average carbon enhancement fraction ([C/Fe] >= +0.7) of 41 +/- 4 per cent for stars with -3 < [Fe/H] < -2 and 58 +/- 14 per cent for stars with [Fe/H] < -3, and report updated success rates for the Pristine survey of 56 per cent and 23 per cent to recover stars with [Fe/H] < -2.5 and < -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 William Herschel Telescope Enhanced Area Velocity Explorer.
