South Polgooth, with historical records dating back to the 16th century, is situated in St. Ewe parish, approximately two miles southwest of St. Austell. Constructed in 1880, an engine house still stands on the site to accommodate a combined pumping and stamping engine. The mine, encompassing Treloweth Mine and New Hewas Mine, primarily worked three main lodes: Hewas Lode, North Lode, and Caunter Lode, accessed through Engine (Main) Shaft, Baldu Shaft, and Treloweth Shaft. Despite its long history, South Polgooth was never a significant tin producer, with historians noting its limited success over the years. The mined lodes contained tin, small amounts of copper, arsenic, and occasional wolfram and sphalerite. South Polgooth experienced periods of inactivity, notably in 1886, 1892, 1894-95, and 1905-08. Although briefly reopened in 1916, minimal underground work was conducted, leading to its closure in 1918. Recorded production includes 115 tons of black tin between 1837-1839 and 1880-1882, while Treloweth Mine contributed approximately 34 tons between 1896-1899 and 10 tons between 1900-1910.
