ABSTRACT:
A portable device for collecting particulate gold bearing material from rock crevices and the like which include a gas engine driven air blower having shoulder straps for mounting on the back of a user, the air blower being connected by a flexible duct to an elongated flexible conduit having a nozzle or crevice tool connected to the conduit front end, a container having an air outlet connected to the rear end of the conduit and adapted to be dragged along on the ground, the duct having an outlet end connected to the conduit in communication with the conduit central passage so that the air blown into the conduit from the blower provides a jet pump action to suck particulate material into the nozzle, through the conduit central passage and into the container for collection with air being discharged through the container air outlet together with a deflector within the conduit central passage for radially deflecting the stream of particulate material flowing within the conduit central passage.
