This should not be confused with Blyth Mines which is located further to the southwest near Hollow Farm.
The Blythe Mines includes a number of workings on Blythe Vein/Pipe, Laund Vein, Hardwork Vein and Grove, and Ditch Vein.
Blythe (Blithe) Vein/Pipe trends northeast from Blythe Engine Shaft and the line of Sutton (White) Vein across the B5056 near the junction with Alport Lane.
Hardwork Vein is shown on a old mine plan ranging roughly east-west from the southside of Alport Lane to the junction with the B5056.
Ditch Vein runs approximately northwest from the B5056 near the north end of Stoney Ley Wood, where it branches to the north from Bakers Vein to a point just past Blythe Vein/Pipe.
The grid reference given is for the area to the south of Alport Lane, south to Harthill Hall Farm.
