Abstract
The present invention uses an Oscillating Disc Cutter (ODC) in a controlled manner to cut rock for assay purposes. The ODC (1) is mounted in an elongate guide frame typically in the form of an open box channel (2). The ODC is located on a carriage (3), the carriage itself mounted on guide rails (4) within the channel (2). The apparatus includes drive means operable to drive the carriage (3) in a rectilinear manner along the rails (4) such that the rails (4) define a cutting path. The ODC cuts a groove of controlled width and depth in a rock face, yielding rock chips that can be used for accurate assay of the face.
