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.
