See also: Ludcott and Wrey United. One of several mines including Ludcott, Wrey, and North Trelawney, Wheal Wrey operated two north-south lodes approximately 120 yards apart. Around 1863, these mines amalgamated to form Wrey and Ludcott United, ceasing operations in 1866. Initially, Wheal Wrey, situated at the northern end of the set, exploited the eastern lode. Opened in 1846 by Capt. Peter Clymo, the mine quickly became lucrative. By 1855, drainage was facilitated by a small 22-inch beam engine, later upgraded to a 60-inch cylinder. Mining operations continued through a shaft 108 fathoms deep, but declining lode values prompted closure. This posed a significant challenge for Wheal Ludcott’s owners, given the interconnected levels between the two mines. Following negotiations, Wheal Wrey was acquired for £3,438 in 1862.
