         MRM Engineering completed the electrical deisgn of the earthing grid three new
         field substations for mine. The design included modelling of the earth grid using
         SafeGrid© design software, analysis of the earth fault levels, and step and touch
         potentials to ensure that the earth systems were compliant with Australian
