Title: Optical power for self-propelled mineral mole

Abstract: Exemplary methods, systems and components disclosed herein provide propagation of light signals from an external source to a borehole mining mole which includes an optical/electric transducer configured to provide propulsive power for the borehole mining mole and its associated mineral prospecting tools. Some embodiments include one or more umbilicals connected from a remote source location to an onboard reel incorporated with the borehole mining mole. The umbilicals are spooled outwardly or inwardly from the onboard reel during traverse of the borehole mining mole along a path in an earthen environment.
