Nice.
(3) is claimed, so there's (1) and the one N of the in-progress grinder.
If it's of any interest, the one N of the grinder has 2 "sponge rooms", that is, rooms filled with sponges. The grinder Monument had none, so I think they may be rare.
[edit: damn, did I not put a coord marker out there?
It's around 1400/2800, T. Sorry about that.]
