Originally named Pool Old Bal, this mine was active in copper mining from the early 18th century until 1784. In 1834, it was revived under the name East Pool Mine, transitioning to tin mining while also producing some arsenic and tungsten. In 1897, it merged with Wheal Agar to form East Pool and Agar Mine. Two preserved beam engines stand as remnants of the mine: the winding engine of Mitchells Shaft and the 90-inch pumping engine on Taylors Shaft, located some distance north of the road through Pool. The shaft is depicted by the Mindat icon, while the engine house stands on the left.
