A method of analysing ore during excavation, wherein the method includes, during excavation, scanning/sensing ore by using an active hyperspectral sensing (AHS) sensor. The scanning/sensing step includes (i) controlling a power spectrum of a light source, and (ii) comparing, by using the AHS sensor, an emitted light spectrum of light emitted from the controlled light source with a light spectrum of reflected/backscattered light which is reflected/backscattered off the ore. The AHS sensor may be directed towards a muck/veneer/stockpile in order to scan ore forming part of, or being located on, the muck/veneer/stockpile.
