Some infrastructure is installed progressively with the decline.
Return raise completed to surface last month and egress commissioned March quarter. From then on return and ladderway developed level by level.
Dewatering is progressive with decline advance providing main pump station not required.
Is one obliged to have a measured reserve before stoping? Preferable but not obligatory. Having sunk the decline and infrastructure costs, perhaps one just gets into ore development and lives with the reserve status. If the orebody location is predictable then why not?
1,000 tpd includes development and stoping ore of course. A cut in ore gives 4.5 x 4.5 x 4 x 3 = 240 tonnes. With a number of levels under development how many ore cuts a day will be achieved on the way down? There are two and possibly three ore blocks in the reserve shape to give scheduling flexibility. Then stoping on the way back up.
I noticed you commented on the reserve grade not being achieved so far. Was that comment based on a reconciliation or simply a comparison of reserve averages to material mined?
