Abstract:
A drill for excavating a bore in the earth includes a steerable boring tool configured to excavate a bore and sensors coupled to the boring tool. The sensors are spaced apart from one another at multiple azimuthal locations around the steerable boring tool and the sensors are configured to detect a mineral property in the earth adjacent the steerable boring tool.
