Crystal settling allowed the heavy minerals to settle to the base with the lighter siliceous minerals remaining at the top. The mine has adits and laterals driven in from the Stillwater Valley side. There are also an internal decline and shaft. Declines parallel to the orebody allow entries to be made into the stoping area by overhand methods. Sub-levels are driven on lifts and drilled downwards.
Blasted ore is recovered from below using LHDs.
Stopes are paste backfilled. The ore is then conveyed to holding bins before loading in the 9t-capacity skips. The remainder is transported by rail or truck. Oversize is passed to a ball mill while undersize is cycled to flash flotation circuits. Scavenger float is recycled via a regrind mill while the tailings are drawn off.
