Title. I need a lot of Malachite and Moonstone ore, and am willing to mine them myself.

Anyone know of any locations?

Do the nodes respawn? If so how long approximately?

Thanks

14 days game time. all mines respawn.

There was a good supply of loose malachite ore lying around the first few chambers of labarynthian when I did the college quest line.

Read in the strategy guide last night they respawn every month.
