A wide range of experiments have been designed over the past decades, searching for Weakly Interacting Massive Particles via their elastic scattering off the target nuclei in a detector medium. The most challenging method is to identify directionality which will provide an unambiguous proof of the galactic origin of dark matter. The measurement of directionality will ensure a clear signal to background separation. In particular, identification of dark matter direction appears only way to pass over the neutrino background. The directional detection of WIMPs requires a detector with a very high spatial resolution. The NEWSdm experiment at LNGS laboratory is proposed to detect the direction of WIMP induced nuclear recoils using newly developed nuclear emulsion and read-out systems with a sub-micron spatial resolution. The discovery potential of the proposed experiment in terms of signal significance is presented.
