Treamble Mine was an inland working on the Great Perran Iron Lode, north-east of Perranporth. Its mineral history includes iron as well as lead, silver and zinc, with nineteenth-century working and later attempts to recover value from the deposit.
Treamble gives its name to several things that need to remain distinct. The mine is not Treamble corn mill, and neither is identical to the mineral railway branch. The railway served a wider mining landscape; a mill in the same valley could be doing a completely different job.
That geography explains why Treamble keeps appearing in stories about ore, water power and transport. Follow the lode westwards towards Gravel Hill, or follow the railway story back towards Shepherds and the Cornwall Minerals Railway network. Connections matter here, but they must connect identifiable places rather than erase the differences between them.
