DUALZ features a contiguous $4'\\times6'$ ALMA 30-GHz-wide mosaic in Band 6, covering areas of $\\mu>2$ down to a sensitivity of $\\sigma=32.7~\\mu$Jy. Through a blind search, we identified 69 dust continuum sources at S/N $\\gtrsim5.0$ with median redshift and intrinsic 1.2-mm flux of $z=2.30$ and $S_{\\rm 1.2mm}^{\\rm int}=0.24$~mJy.
