Long Rake / Ladies vein runs towards the junction of River Lathkill and River Wye, where Black Sough (to Ladies Vein) is shown to be a channel leading to the Wye.
The Long Rake system I believe is the northern extent of this part of the mineral field, thus nothing north of it until westish of Bakewell.

When do I get my soapbox, I need to rant on about some b***cks
