[@Stitches] I think what Acer was trying to convey was that the shack has an entrance to the shaft itself inside it.

Ah, damn. Eli went into the mine - we'll have to change our collab a fair bit, then. Who's still outside? Also could someone explain where precisely we're staying? Because the shack looks like the most likely option, but Eli's post suggested that there was somewhere better deeper within the mine.

Just give a shout, Eli will come running.
