ABSTRACT The method is used in the selective recovery of ore-bearing reef from arock mass in a mine. The method involves forming spaced apart access gullies in the rock mass, the gullies extending in the direction of mining. A wire saw is then used to form cuts in the rock mass, the cuts extending between the gullies and being situated just above and just below the reef. Thereafter, the reef is recovered from between the cuts while barren rock above and below the reef is left intact.
