Graig Fawr Red Ash, 2005

The Ebbw Vale Steel, Iron & Coal Co. Ltd. started sinking this mine in 1887 on the site where formerly existed a siding connection with a colliery that the Ebbw Vale Co. had sunk, but as they abandoned.

From the Inspector of Mines list 1896, the workforce numbered 97 including 10 surface workers.

By 1908 it was listed with the nearby Marine colliery.

Where the Tillery rises close to the surface it often appears to have a reddish hue and in this area it is sometimes known as the Red Ash seam.

Later the pit was abandoned and levels were driven into the mountainside to work the Red Ash seam.

In 1918 and 1923 the workforce numbered 137 and 75 respectively.

It closed in 1928
