Wheal Muttrall (there are a number of variant spellings) and Wheal Gorland were two totally separate cost book mines.
Wheal Muttrall existed as a stand alone mine from at least as early as 1787 when Martin Henry Klaproth (translated the German of John Gottlob Werner), stated that 'Tin-stone and Wolfram is found at Wheal Mutterel in Gwennap'.
Furthermore, shares in the already existing Wheal Muttrell and Wheal Gorland were offered for sale in 1793.
Earlier shares offered for Wheal Gorland were offered in the Sherborne Mercury in 1772.
Wheal Muttrall continued to operate independently until 1799.
By 1800 the two mines were amalgamated and continued trading thereafter as Wheal Gorland.
Wheal Muttrall exploited the singular Muttrall lode, whereas Wheal Gorland comprised a number of East - West coursing lodes.
Specimens from Wheal Muttrall prior to 1800 should be designated as coming from Wheal Muttrall, Gwennap.
From 1800 they should be listed as coming from the Muttrall Lode, Wheal Gorland, Gwennap.
From a purely geographic perspective it is entirely correct to say that Wheal Muttrall and Wheal Gorland are located within St Day village and consequently the modern St Day parish.
The following is written by a.K. Hamilton Jenkin regarding Wheal Muttrall (also spelt Muttrell):
"During the 1790's the northern part of Wheal Gorland had been worked under a separate grant known as Wheal Muttrall. Through being connected to the County Adit, here about 50 fathoms below surface, no engine was required and £1249 worth of copper ore was sold by the little mine beteen 1795-8. The lode, however, was chiefly productive of tin and when subsequently merged with Wheal Gorland was developed to an inclined depth of 126 fathoms."
The grid reference approximately marks the site of Muttrall's Shaft.
