Mining
Mining is done from large boulders that contain bountiful deposits of jade. Jade is exposed using diamond-tipped core drills in order to extract samples. This is done to ensure that the jade meets requirements. Hydraulic spreaders are then inserted into cleavage points in the rock so that the jade can be broken away.
