The decline will only be to the top of the ore-body INDEEP,
If they do decide to go straight to block-cave (which I doubt - it sounds like they will do selective top-down mining first) then they would drop down the side of the ore-body in stages, allowing them access to the ore-body to drill and places charges, markers, etc as they go.
