From what I can gather the Boarskin and Peisteskin maps can only be gotten through fishing... is this correct or am i missing something?

Patch notes say

Timeworn Boarskin Map: Level 50 mature trees, lush vegetation patches, mineral deposits, rocky outcrops, and fishing holes (Reaver Hide and the Tangle only)
Timeworn Peisteskin Map: Level 50 mature trees, lush vegetation patches, mineral deposits, rocky outcrops, and fishing holes (Lake Tahtotl, Parata's Peace, and the North Shards only).
and I can't seem to find any mining / logging nodes in these areas.

can anyone shed some light on this?

please and thanks.
