The ore body at Mimosa is shallow and mining commences at
a depth of only 150m below surface and extends to a depth
of approximately 200m. The bord and pillar mining method
is employed and stoping widths average around 2m. Mining
bords advance along the strike. The mining cycle involves
mechanised support drilling and installation, mechanised face
drilling, charging and blasting, and mechanised lashing onto a
conveyor network to an underground bunker. From the bunker
ore is conveyed out to a surface stockpile.
