The various Lovells are a bit of a nightmare. Whilst HJ locates 6 in Wedron Tin on the maps included, he states that "by the 1800s the number of Lovell mines or projects had increased to nearly a dozen" and names North Lovell, South Lovell, Lovell Consols, Old Wh Lovell, The Lovell, New Wh Lovell, Great East Lovell, East New Wh Lovell, Great Wh Lovell and Lovell United.
He also says that "This profusion is rendered the more baffling by the apparent inconsistency with which the mines are referred to by Collins, Dines (the other main refs for Cornish Mining) and on the OS 6 inch maps". There is obviously a degree of duplication and overlap with some of these mines (HJ particularly notes inconsistencies between reports of The Lovell, Old Wh Lovell and Wh Lovell by Collins and by Dines). I'm not sure given the various inconsistencies that it is possible to sort them all out at this remove.
For what it's worth, HJ (who I tend to give the most credence to) says this:
The Lovell - Situated on Tregunstis farm about half a mile south of Seworgan and developed to a depth of 45 fathoms. After the failure of the Tregunstis part, a separate company was formed with the sett including Mengearne and Combellack Mines. None of the workings appear to have been particularly rich.
Downstream from The Lovell, South Wedron Mine, otherwise known as South Lovell and later Lovell Consols is shown on the 1888 OS map. This seems to be another mine that doesn't appear to have been particularly successful.
Adjacent to Laity on the Helston-Falmouth Road a number of shafts shown on the 1888 map formed part of the New Wh Lovell sett. It was never successful.
Great East Lovell on the eastern edge of Polangrain Moor was unsuccessful and was said to be a swindle got up to work untried ground on the back of successes elsewhere.
East New Wh Lovell was in reality little more than a name.with two shafts sunk to a max of 22 fathoms with no lateral development. A map of 1870 shows the mine a short distance west of Treleggan farm.
North Lovell, to the east of Garlindna Mine, was sunk to 30 fathoms but produced very little tin.
HJ concludes by describing the Lovell group as "the most complex set-up in Cornwall , as this writer has cause to know"
Fascinating stuff, but I'm not sure it solves the riddle.
There is also New Trumpet and Lovell United Mine in the database. HJ says nothing about Lovell United apart from mentioning the name. But neither HJ nor Dines link either of the Trumpet mines with Lovell United.
