I have kinda got the hang of prospecting as much as i feel possible but i just keep getting weird readings such as this:

So as you can see in the picture the readings on the left point to the top right, and the readings in the top right point to the top left.
And ive discovered no ore, I understand the ore can be beyond the cavern walls but as i got closer (I STARTED FROM THE LEFT) it started to curve its way around the cavern? i just don't get it? also i understand that ql 20 rustroot = a 50 tile radius around your user so that's 25 tiles in each direction?
Anyone have any ideas?
(EDIT: NOTE. THERE IS A 4th READING INBETWEEN THE MAP AND BOX WITH ANGLE IN IT(TOP RIGHT))
