We report the discovery of the quadruply lensed quasar J1433+6007, mined inthe SDSS DR12 photometric catalogues using a novel outlier-selection technique,without prior spectroscopic or UV excess information. Discovery data obtainedat the Nordic Optical telescope (NOT, La Palma) show nearly identical quasarspectra at $z_s=2.74$ and four quasar images in a fold configuration, one ofwhich sits on a blue arc. The deflector redshift is $z_{l}=0.407,$ fromKeck-ESI spectra. We describe the selection procedure, discovery and follow-up,image positions and $BVRi$ magnitudes, and first results and forecasts fromsimple lens models.
