Carnon Mine was a tin mine at Restronguet Creek, near the village of Devoran in Cornwall, England. A ruined engine house survives on the north bank of the creek. It is a Grade II listed building. [1]
The tin mine opened in 1824. The surviving engine house is thought to have housed an engine of cylinder diameter 24 inches. An artificial island was created in the estuary; shafts, in the form of cast iron cylinders made at Perran Foundry, were sunk there, and a 14-inch engine and horse whim erected. Water was pumped from the mine by the engine on the estuary bank via flatrods. [2]
The mine was profitable, but closed in 1830; the Redruth and Chasewater Railway complained that boats using the creek were obstructed. [2]
The south-east wall and parts of the north-east and south-west walls of the engine house survive, to a height of two storeys of the original three storeys. The south-west wall, the "bob wall" that supported the beam of the beam engine, is thicker than the others. [1]
The River Camel is a river in Cornwall, England. It rises on the edge of Bodmin Moor and with its tributaries its catchment area covers much of North Cornwall. The river flows into the eastern Celtic Sea between Stepper Point and Pentire Point having covered about 30 miles, making it the second longest river wholly in Cornwall. The river is tidal upstream to Egloshayle and is popular for sailing, birdwatching and fishing. The name Camel comes from the Cornish language for 'the crooked one', a reference to its winding course. Historically the river was divided into three named stretches. Heyl was the name for the estuary up to Egloshayle, the River Allen was the stretch between Egloshayle and Trecarne, whilst the Camel was reserved for the stretch of river between its source and Trecarne.
The River Fal flows through Cornwall, England, rising at Pentevale on Goss Moor and reaching the English Channel at Falmouth. On or near the banks of the Fal are the castles of Pendennis and St Mawes as well as Trelissick Garden. The River Fal separates the Roseland peninsula from the rest of Cornwall. Like most of its kind on the south coast of Cornwall and Devon, the Fal estuary is a classic ria, or drowned river valley. The Fal estuary from Tregony to the Truro River was originally called Hafaraell.
A beam engine is a type of steam engine where a pivoted overhead beam is used to apply the force from a vertical piston to a vertical connecting rod. This configuration, with the engine directly driving a pump, was first used by Thomas Newcomen around 1705 to remove water from mines in Cornwall. The efficiency of the engines was improved by engineers including James Watt, who added a separate condenser; Jonathan Hornblower and Arthur Woolf, who compounded the cylinders; and William McNaught, who devised a method of compounding an existing engine. Beam engines were first used to pump water out of mines or into canals but could be used to pump water to supplement the flow for a waterwheel powering a mill.
Poldice mine is a former metalliferous mine located in Poldice Valley in southwest Cornwall, England, United Kingdom. It is situated near the hamlet of Todpool, between the villages of Twelveheads and St Day, three miles (5 km) east of Redruth. Since the early 2000’s the area has been adopted by the local mountain biking community known as the Dice Rollers. The area is now nationally famous as the best location to ride MTB in the south west attracting attention from youtube superstars such as Ben Deakin and his friend Matt Edgie. This is a popular location for mountain bicycling
Levant Mine and Beam Engine is a National Trust property at Trewellard, Pendeen, near St Just, Cornwall, England, UK. Its main attraction is that it has the world's only Cornish beam engine still operated by steam on its original site. There is also a visitor centre, a short underground tour, and the South West Coast Path leads to Botallack Mine, via a cliff-top footpath.
Perranarworthal is a civil parish and village in Cornwall, England. The village is about four miles (6.5 km) northwest of Falmouth and five miles (8 km) southwest of Truro. The parish population at the 2011 census was 1,496.
Towan is found in many placenames in Cornwall. However, The Towans usually refers to the three-mile (5 km) stretch of coastal dunes which extends north-east from the estuary of the River Hayle to Gwithian beach with a midpoint near Upton. The South West Coast Path crosses the towans.
A Cornish engine is a type of steam engine developed in Cornwall, England, mainly for pumping water from a mine. It is a form of beam engine that uses steam at a higher pressure than the earlier engines designed by James Watt. The engines were also used for powering man engines to assist the underground miners' journeys to and from their working levels, for winching materials into and out of the mine, and for powering on-site ore stamping machinery.
The Redruth and Chasewater Railway,, was an early mineral railway line in Cornwall, England, UK. It opened in 1825 and was built to convey the output from copper mines in the Gwennap area to wharves on Restronguet Creek around Devoran, and to bring in coal to fuel mine engines; later it carried timber for pit props and also house coal.
The Hayle Estuary is an estuary in west Cornwall, England, United Kingdom. It is one of the few natural harbours on the north coast of south-west England and during the prehistoric and early medieval periods was important for trade and the movement of people and ideas.
Dolcoath mine was a copper and tin mine in Camborne, Cornwall, England, United Kingdom. Its name derives from the Cornish for 'Old Ground', and it was also affectionately known as The Queen of Cornish Mines. The site is north-west of Carn Brea. Dolcoath Road runs between the A3047 road and Chapel Hill. The site is south of this road.

Wheal Peevor was a metalliferous mine located on North Downs about 1.5 miles north-east of Redruth, Cornwall, England. The first mining sett was granted here in around 1701 on land owned by the St Aubyn family. It was originally mined at shallow depths for copper, but when the price for that metal slumped after 1788, the mine was able to change to mining tin ore, which was found deeper down. In the late 18th century Wheal Peevor had the advantage of being drained by the Great County Adit which was around 100 metres deep here. The mine covered only 12 acres but had rich tin lodes. In addition to tin and copper, pyrite was also mined here between 1872 and 1887.
Wheal Busy, sometimes called Great Wheal Busy and in its early years known as Chacewater Mine, was a metalliferous mine halfway between Redruth and Truro in the Gwennap mining area of Cornwall, England. During the 18th century the mine produced enormous amounts of copper ore and was very wealthy, but from the later 19th century onwards was not profitable. Today the site of the mine is part of the Cornwall and West Devon Mining Landscape World Heritage Site.
East Pool mine, was a metalliferous mine in the Camborne and Redruth mining area, just east of the village of Pool in Cornwall, England. Worked from the early 18th century until 1945, first for copper and later tin, it was very profitable for much of its life. Today the site has two preserved beam engines and is part of the Cornwall and West Devon Mining Landscape World Heritage Site. It is owned by the National Trust.
