Abstract: I will present a calculation of the rate of information release from a Schwarzschild  black hole within a proposed extension of Hawking's theory of black hole evaporation. Our proposal accounts for quantum fluctuations of the background geometry, as well as for classical back-reaction and time-dependence effects. The two-point function matrix for the emitted radiation consists of Hawking's thermal matrix plus off-diagonal corrections that are initially small and becomes more important as the evaporation proceeds.   If the phases and amplitudes of the radiation matrix are recorded over the lifetime of the BH, then it can be shown that the radiation purifies in a continuous way.
