brunnhildar village - grayed out veins on map

dear community,

i'm currently leveling my first char on this server, so i don't know yet how "everything works here" (and i never played on an official server, so i only have other privat servers as reference). i reached the brunnhildar village in stormpeak and notices plenty of greyed out oreveins on my map, when i'm in the village - as if there are mines/tunnels below the village. but i cannot find any entrance - or at least no cave that lead to the mentioned veins. how do i reach them? do you know what i mean?

thanks and have a nice day

There's an entrance to a cave north of K3 which is probably the spot you're looking for.
