Any idea where to get them? I've been getting the other materials (Black Stone, Small Stone, Small Lumber and Lumber), but no luck on the two I've listed. I know Corona sells Stone, but I'm broke.

Stone is just a normal rock, so there is really not much difference between it and Small Stone with regards to randomly appearing on the ground. Black Branches come from the Safari zone.

I read that you can fish for black lumber as well. You can also just buy Stone.
