The most metal-poor stars provide valuable insights into the early chemical enrichment history of a system, carrying the chemical imprints of the first generations of supernovae. The most metal-poor region of the Sagittarius dwarf galaxy remains inadequately observed and characterised. To date, only a handful of stars with Fe/H-2. 0, given the relatively low Co/Fe in this metallicity region.
