Great Hewas Mine in St. Mewan parish was also known as Hewas Downs Mine or Great Hewas United and also included Ventonwyn Mine. It also worked with Kingsdown or Hewas Water Mine. Known to have been at work in the 1790's, the mine finally closed in 1926.
Including Ventonwyn Mine (previously known as Wheal Elizabeth), the mine worked several lodes for lead, silver, copper and tin.
The chimney of Ventonwyn Stamps engine house is a prominent landmark on a ridge north of the Truro to St. Austell road. This small tin mine lies about half a mile northwest of Hewas Mine and worked from 1903, also working for a time with the nearby Great Dowgas Mine.

Hewas (From 1821) - 482 tons of 5.75% copper ore
Great Hewas (From 1856) - 19 tons of 64% lead ore and 48 ounces of silver
Great Hewas United (1854-60) - 867 tons of black tin and
Kingsdown (Hewas Water) Mine (1919-26) - 24 tons of black tin per month.
