MINING paste fill ( derived largely from tailings ) and longhole echelon retreat methods . “ Our rapid progress is attributable in part to the location of the orebody . From an underground mining perspective Nova is quite shallow , with the 1,000 metre long orebody positioned about 200 metres from surface down to a maximum of 500 metres ,” he points out . “ It is a large flat-lying orebody somewhat in the shape of a banana !”
Had it been deeper , shaft access may have been considered but given the proximity to surface the orebody is being accessed by declines which have been dug to accommodate the 60-tonne trucks that will bring out the ore . Thanks to being
