A method of analysing ore, wherein the method includes, during excavation, scanning/sensing ore, by using a sensor. The sensor is located at a position which is (i) spaced from a bucket/shovel of an excavator and (ii) operatively higher relative to the bucket/shovel. The sensor is also directed towards the bucket/shovel, so that the sensor can scan/sense operatively downwardly towards/into the bucket/shovel. The sensor may be secured to, or mounted on, an excavator at a position which is spaced from a bucket/shovel of the excavator.
