Polberro Mine
Polberro Mine is situated on the hillside above St Agnes and was said to produce the finest tin ore in Cornwall. This included very pure tin (known locally as "diamond tin") that needed little processing. By 1750 the mine was operating as one of the largest in Cornwall, with so much tin ore produced that there were not enough packhorses in the St Agnes area available to carry it. By the early 1800s it employed around 450 people and produced 30 tonnes of tin ore per month. Its extensive operation was described by the local newspaper in 1843 as "...a surface of upwards of 200 acres, and contains 24 shafts, 9 of which are now in full working, with 3,000 fathoms of levels...".
