East Pool Mine dates its beginnings back to the early C18th when a small concern called “Pool Old Bal” worked a sett. This was leased by the Basset family up to the mid 1780’s.
The mine named East Pool began its life during 1834. Completely surrounded by large well established mines: South Crofty, Tincroft, Wheal Agar and Carn Brea. Its small sett was highly profitable, the shallow workings produced a high grade Copper Ore. This sold for almost twice the price achieved by other mines.
Wheal Agar was the northern neighbour which had struggled to make a profit apart from a short period during the 1880’s. Wheal Agar eventually closed in 1895, the workings soon started to flood to a point where the East Pool system was threatened.
East Pool was the more profitable mine, from 1862 until the drop in Tin prices in 1894 good profits were returned. Also the dividends paid to the shareholders were often higher than those from Dolcoath. East Pool produced a variety of ores, apart from Tin and Copper significant amounts of Wolfram were discovered in the 1860’s along with Arsenic, Cobalt, Nickel and Uranium.
After a period of negotiations East Pool finally purchased Agar Mine and associated equipment for £4,000 thus creating East Pool and Agar Mine in March 1897. The workings were eventually closed in 1945. However the impressive Beam Engine on Taylor’s Shaft continued to pump from South Crofty until electric pumps took over in September 1954.
In total the mines worked from 1835-1945, East Pool produced 88,3000 tons Copper, 38,490 tons Tin, 31,722 tons Arsenic and 2,820 tons of Wolfram. Wheal Agar produced 3,033 tons of Copper.
The following pages show external and internal views of the two remaining preserved Engine Houses. Now managed by the National Trust they are open to the public on a regular basis throughout the year. All these images were taken in April 2012.
The following images on this page were taken inside the Winding Engine House. I was there just as it opened so I was the only one inside. So, this gave me an amazing opportunity to get some internal images without the worry of visitors in the way. I was able to use the flash quite happily, I think I got some good results.
My thanks go to the kind lady from the National Trust who made me a cup of coffee and biscuits. Also she and took an interest in what I was doing.
The boiler is a single flue Cornish Type made by Ruston and Hornsby Ltd in 1926. It was reclaimed from the Poor Law Institution in Truro where it supplied steam for the laundry. When the mine was working there would have been two boilers powering the engine. Along with various tools stacked up in the background on the right is part of the steam feed pump for the boiler water.
Up the steps to the first floor, known as the Driving Floor.
Moving up the stairs to the Middle Chamber. This is where the top of the cylinder and the piston are to be found.
The next set of images were taken on the top floor of the engine house. The home of the Beam.
Moving outdoors to the Bob Plat, this was where the outdoor part of the beam could be maintained. It also allows for great views of the surrounding area.
The Processing Plant for the Mine was located in the Tolvaddon Valley through which the Red River flowed. The ore was transported from the mine to here by a mineral tramway which operated until 1934. After the closure an aerial rope way was used until the mine finally closed during 1945. There are still extensive remains in the valley, although much is now fenced off. The images below were taken during the mid 1990’s before the site became too overgrown.
