Hazlerigg Colliery. This was opened 1892 by the Burradon and Coxlodge Coal Company. It transferred in 1929 to the Hazlerigg and Burradon Coal Company Ltd, then to the National Coal Board in 1947. Closed 25th November 1964. There was a pumping shaft at NZ 227 717.

This Shaft is marked as ‘Old’ on the 2nd edition Ordnance Survey plan, indicating that it was out of use by 1895. It is marked by the British Geological Survey as " Three Pool ". This area has been mined for hundreds of years. 'North Pit Field' and 'South Pit Field' on the early 19th century Woolsington Estate plan (NRO 1219) presumably indicate the location of a coal pit or pits.

This Shaft is marked as ‘Old’ on the 2nd edition Ordnance Survey plan, indicating that it was out of use by 1895. It is shown by the British Geological Survey as a shaft in Beeftub Plantation, along with a second shaft immediately south within the Plantation called "Water Gin".

This Quarry appears on the 2nd edition Ordnance Survey plan, where it is marked as ‘Old’, but is not shown on the 1st edition plan, indicating that it dates from the period between 1858 and 1895.

An aqueduct was built from Whelton reservoir in Whittle Dean to Throckley Filter Beds in 1869. The water treatment works with extensive filter beds were completed in 1875 for the Newcastle and Gateshead Water Company. This involved extensive terracing and excavation of the area of the treatment plant, during the course of which the 'Walbottle Hoard' (SMR 1421) was found. The water treatment works were reconstructed in 1956. The filter beds have suffered from a degree of subsidence over the years. The valve houses (HER 1964 and 1965) are listed buildings {1}. Northumbrian Water has decommissioned the water works at Throckley and the site will be redeveloped in due course. Tyne and Wear Museums were appointed to record this industrial site. The water treatment works with extensive filter beds were completed in 1875 for the Newcastle and Gateshead Water Company, and linked to Whelton Reservoir in Whittle Dean by an aqueduct. The works were reconstructed in 1956. The two valve houses on either side of Hexham Road are listed grade 2. The northern valve house of 1870 stands within the waterworks site and is built of snecked sandstone with pecked quoins and dressings. It has a Welsh slate roof with overhanging eaves and a lead ball and spike finial. A sandstone block wall with semi-circular ashlar coping encloses the site and there are three sandstone gatepiers with chamfered edges next to Throckley Lodge. The naturally sloping site is retained by huge sandstone block revetment walls with red brick buttresses which allowed the site to be levelled some 3m above the height of Hexham Road. Arches in the base of the buttresses allow water to flow through a channel behind the wall. Above the sandstone wall is a five course red brick wall with ashlar coping stones. Inside the site are two tanks for aluminium sulphate, an administration building built in 1955, an electricity substation, two concrete filtration tanks, a settling tank with 24 courses of red brick and 12 courses of black-finished brick and chamfered concrete coping slabs and base. The filter beds are of similar construction, bordered by steel railings and with dividing walls forming catwalks. Water filtration removes colour from the water caused by peat or soil. The settling tanks allow the sludge to settle. The water is then filtered – originally through layers of sand and gravel, later through anthracite. Aluminium sulphate removes any remaining discolouration, lime maintains the alkalinity and chlorine the purity of the water, which was then pumped from the site by boaster pumps in the valve houses. A limited archaeological survey was undertaken in 2013 of the chamber below the north valve house.

The first shaft sunk at the colliery was 'Old Fred Pit' started in 1891, and North Walbottle Colliery opened in 1892. Subsequently, Betty Pit opened in 1893 and Mary Pit was sunk in the same year and completed in 1894. Its coals were almost certainly transported to Lemington via the inclined plane. The Betty and Mary shafts were served by two magnificent steam winding engines (circa 1900) which were in turn served by boilers, of which two were the original hand-stoked versions. Also working until modern times were two steam powered water pumps and a steam powered drop-hammer. The colliery was notable for its drifted access saving travelling time underground, its pithead baths, its associated colliery village and for several other features. The principal owner before 1947 was the North Walbottle Coal Company. The colliery closed in 1968.
The site was redeveloped for housing in the 1970s, and the locations of two of the shafts are now preserved as flower beds with low stone walls in the verge of Mandarin Close, between numbers 4 and 10.

Callerton Colliery is first shown on the Ordnance Survey second edition map, indicating that it dates from after 1858. It lies to the north of Lough House (HER19173). Modern aerial photography shows that that some buildings survive, although the site is overgrown.

This Air Shaft, possibly related to Callerton Colliery appears on the 2nd edition Ordnance Survey plan but is not shown on the 1st edition plan, indicating that it dates from after 1858.

This was the Rolling Mill for Spencer's Steel Works (HER ref. 4231). It was built circa 1900 and probably produced the steel plate for the Mauretania in 1904. The works closed in the 1960s but this building survived and was reused.

The firm of John Spencer and Sons Ltd. was founded in the year 1810 by John Spencer who had been an apprentice in the Sheffield Steel Works, and afterwards was employed for some time at the works of Crowley and Millington at Winlaton. Spencer's original works was established at Newburn in 1822, when he acquired a water mill from the Duke of Northumberland and converted it for file grinding. This mill, later used for rolling steel, was known as Number 1 mill, and was situated in Walbottle Dene, behind the fire station of modern times. In 1824 John Spencer took into partnership his brother William, and in 1830 further land was acquired, along with a 30 foot breast wheel situated some distance from the corn mill. This became the grinding mill proper and converting furnaces were built, and a crucible plant. The works concentrated on making springs for the Railway industry and by 1900 had expanded to cover 60 acres and employed 1800 people. By this time they had diversified into steel plate and in 1904 produced the plate for the "Mauretania". In the 1920s the firm collapsed but was revived in 1928 as John Spencer and Sons, making railway axles and springs, then gun springs and barrels during World War Two. The firm closed in the 1960s but some 19th century buildings survive on the original site in Walbottle Dene, whilst on the later larger site between Lemington Road and the river, one major building from the steelworks has been reused. The stone buildings used by North East concrete on Walbottle Road have been demolished to make way for housing, but were recorded beforehand (Tyne and Wear Museums 2005). The only remaining building is now Clayton House on Walbottle Road. There was an archaeological desk based assessment of the Woodside Haulage Site in 2004 (Tyne and Wear Museums). This was followed by two phases of evaluation trenching in February and March 2005 and April and May 2006 (Tyne and Wear Museums, August 2008). The subsurface remains of the steelworks including the extensive flue system survives in excellent condition. The remains are part of the c.1872 expansion of the steelworks which co-incided with the introduction of a Siemens open hearth furnace for the Siemens-Martin Acid Process of mass production of steel for construction and ship building. The Newburn works represents an early example of manufacturing Siemens steel.
