Looking for a spot to do cobalt with my biped.

West of Morathaven is a great spot to do it as there are Rich/ML of both nickel and cobalt near a smelter, but it's a long way from a portal and without being able to fly travel time is bad.

North of Dralk is a decent spot for cobalt, but not much nickel up there and you have to drag it back to town to work it up.

Is there another spot that's better?
