(Centred NY 893834) Beneath the limestone escarpment near the Steele farmhouse, are rounded shallow pits, with heaps of slag, indicative of the remains of old ironstone workings. The workings stretch for several hundred yards above the terrace lines, where a great mound or hill of iron scoria occurs. The native iron found in nodules near the surface, is very rich, and appears to have been worked in all ages.
The workings may probably be referred for the most part, to the Romano-British period. (1)

The military workshops at Corbridge, active in the 3rd and 4th centuries AD were using iron ore brought in as low grade smeltings from native hearths. The source of the material was undoubtedly the Redesdale deposits just south of Habitancum; and it was used again on Tyneside much later for Armstrong's early munitions works. (2)

Centred NY 89228371 and NY 88918411. The area indicated by Rome Hall is now covered by the slag heaps of the modern workings but to the north west are two areas with traces of much older and cruder workings.
The larger and more southerly area is on the 800 foot contour at the foot of the escarpment which lies to the north east. The area is very disturbed with many shallow pits 10m to 20m in diameter and up to 1m deep, with corresponding spoil and slag heaps.
The smaller area is also on the 800 foot contour. The ground is very disturbed but the pits and heaps are less well defined than the southern area.
Although there is no dating evidence it is probable that this is part of the area worked during the Roman-British period. (3)
