Polgooth is a former tin-mining village in south Cornwall, England. It lies mainly in the parish of St Mewan and partly in the parish of St. Ewe. The nearest town is St. Austell two miles (3.5 km) to the north-east.
John Marius Wilson, in his Imperial Gazetteer of England and Wales (1870-72)) describes it as a very extensive tin mine. Wikipedia is even more explicit.

One of the many maps available on A Vision of Britain through Time is one from the Ordnance Survey Series of 1900 illustrating the parish boundaries of Cornwall at the turn of the 20th century. This map blows up to show all the parishes and many of the small villages and hamlets.
