Coal in the Yorkley Delf vein adjoins Kidnals Wood.

14 September 1846 A report on the Bailey Hill Level Colliery.  Contains about 300 acres, or 1,452,000 square yards.  The thickness of the vein is stated to average two feet nine inches in thickness, although from miners who have worked this and in the adjoining Kidnall´s Colliery grounds exist to believe that it may exceed this.  Assuming the thickness as above then each square yard would produce half a ton, the colliery therefore containing 726,000 tons.
There are three shafts sunk, the deepest of which is seventy yards all of which are drained and ventilated by a level.
The heading, or level road has been carried on from the deepest shaft, about one hundred and twenty-two yards to the southward, and about thirty yards to the northward, and only about ten acres have been cleared.
Were a slope to be worked up from the vein from the deep level to the cropping, and a small engine erected to draw up the coal, together with the deep pit now fitted up with a horse gin, it might with an outlay certainly not exceeding £500 be made to produce 100 tons per day.
The direct distance from this property to the Severn at Purton is about three miles.  The Severn & Wye tramroad on the west side passed within six hundred yards and possesses an easy descent for connection in either direction.
