The mining deposit at X: 24.9, Y: 22.2 is not visible on the minimap nor in the world. However, the ability "Lay of the Land" will point to this spot as if there is a mining point there. There are no current mining points available to mine granite as such, as I have exhausted the other mining points, and require to get an open world non-ixal mining point to refresh these mining points.
