Wheal Martha mine is at Luckett Village, on the River Tamar in Cornwall. The Wheal Martha Mine has worked a complex lode carrying copper, arsenic, silver, wolfram, tin and pyrite, intermittently and under a number of names. Wheal Martha (1836), Great Wheal Martha (1844-49), New Wheal Martha (1861), and in combination with other adjoining properties, New Great Consols (1867) and finally New Consols.
The old mine was originally worked for copper, then for deep tin beneath shallow copper deposits. And later known as the New Consols Silver and Arsenic Works.
1848 The mine closed
1851 reopened but only worked sporadically for a few years. Another unsuccessful attempt, under the name New Consols, commenced a few years later.
1877 the abandoned mining machinery lay undisturbed from 1877 until it was broken up and sold for scrap in 1938.
The dumps were worked after World War I.
Re-opened unsuccessfully between 1946 and 1952 when it was reported that £400,000 had been invested with only a return of £100,000 of tin ore. In this last venture, electric power was provided from two generators driven by two large diesel engines, one Paxman and the other a Mirlees.
