I noticed this statement in the PREliminary report.

Slashing and modernization of the 26 level (4,000 ft) continued in order to provide fully mechanized access for mining and haulage

Could this be improvements to the D-winze and possibly a conveyor from the D shaft over to the A shaft, or is it just to improve efficiency on the 26 level. In any case it appears that the 26 level is going to be a main focus for mining upwards towards the economic limits of the surface ramps.
