We present the first results of the EMBLA survey ( Extremely Metal-poor BuLge stars with AAOmega ) , aimed at finding metal-poor stars in the Milky Way bulge , where the oldest stars should now preferentially reside .
EMBLA utilises SkyMapper photometry to pre-select metal-poor candidates , which are subsequently confirmed using AAOmega spectroscopy .
We describe the discovery and analysis of four bulge giants with -2.72 \leq [ Fe/H ] \leq -2.48 , the lowest metallicity bulge stars studied with high-resolution spectroscopy to date .
Using FLAMES/UVES spectra through the Gaia-ESO Survey we have derived abundances of twelve elements .
Given the uncertainties , we find a chemical similarity between these bulge stars and halo stars of the same metallicity , although the abundance scatter may be larger , with some of the stars showing unusual [ \alpha /Fe ] ratios .
