Seam-style ore deposits will be returning to Mining in Dragonflight Patch 10.0.7, having not made an appearance in game since Battle for Azeroth. Seams of Serevite and Draconium have been spotted in the new Forbidden Reach zone.
These large deposits yield about twice as much Serevite Ore and Draconium Ore as normal mining deposits. You can get more with higher Finesse:Serevite SeamDraconium Seam Serevite Seams can be mined for skill until Dragon Isles Mining (50), while Draconium Seams give experience right up through Dragon Isles Mining (100).
The first time you mine a Serevite Seam or Draconium Seam, you'll get +1 Knowledge point and +15 Artisan's Mettle for each. Seams do not appear to have any modifiers such as Rich, Titan-Touched, Molten, etc.
On the current PTR, Serevite Seams and Draconium Seams are uncommon and only appear inside caves within Forbidden Reach. So far, none have yet appeared outside caves.
