Phase boundaries of 3He-4He mixture confined in an aerogel of 87% porosity are mapped out by a torsional oscillator experiment. The superfluid transition line is found to extend to T=0 on the high 3He concentration side of the phase diagram. However, we are able to trace the phase separation line only on the 4He-rich side of the phase diagram.
