West Tolgus

It lies just off the A30 road south of Illogan, northeast of Camborne and northwest of Redruth.

[1] It produced over 1500 tons of copper ore of a moderate grade in the period that followed but was again closed.

[1] Managed by Captain Joseph Jewell,[2] they built an engine house with a 60-inch (later 65 then 70) pumping engine and a 10-foot stroke, enabling mining to reach a depth of 312 feet or 52 fathoms by April 1862.

[1] During the 1870s, a series of accidents caused the mine to flood, including in 1873 when flooding closed the mine for five months, and in January 1879 when the balance bob broke in two places in Richards' Shaft.

[1] The damage led to increased costs and wet mining conditions, leading to its eventual abandonment.
