Guild Wars 2

When doing the Incinerator precursor collection, I managed to destroy (intentionally even, not accidentally) Nickel and Zinc Ore which are required to craft Lumps of Invar and Mizin, respectively, before having crafted those.

Is there any way to get the ores again, so that I can craft the lumps I need?
Will they drop again when mining? (no such luck so far, but it took a few dozen attempts the first time, too)
Will they be added to Craftsman Hobbs in the future? (so far, his “misplaced items” tab is empty for me)

Thanks for any info on the matter.

They drop multiple times but I do not know the drop rate. Best bet is to try different maps that have the nodes you are looking for.

I see.
Must be rng and bad luck on my side then. I’ll keep digging!

Thanks

update: I mined nearly a hundred more nodes and finally did get nickel ore again.

Now, for that elusive zinc ..
