Oil is separated from oil sands using an elongated probe member with a semi-circular front surface and a tapered rear surface so that the probe member is advanced forwardly through the oil sands when vibrated. Protrusions on the surface agitate the oil sands to assist in releasing the oil sands and a rearward tail portion pacts the sand after the oil is released. Vibration may be accomplished by a static pressure conduit and a cyclically variable pressure conduit alongside one another in the longitudinal direction of a resilient body of the probe. A probe support assembly may support several probe members circumferentially spaced from one another so as to be oriented to rotate the assembly in a common circumferential direction when vibrated in respective forward directions.
