Yes this is what http://www.newton.dep.anl.gov/askasci/gen01/gen01008.htm has to say:

As the salt dissolves in the meltwater, intermolecular bonds between water molecules in the ice lattice are broken. Bond breaking processes always require energy. The energy flow to enable the breaking process comes from the surroundings. If you were to be holding the glass containing the ice-salt-water mixture, heat energy would flow out of your hand into the glass. Heat flow away from you is perceived as cold.
