Part of Basset And Buller Consols.

East Wheal Basset was situated north of the road east of Carnkie, on rising ground east of a stream. Initially established during the 1830s, it later became part of Wheal Buller before separating and operating independently in 1851. Although relatively short-lived, operating from 1857 to 1877, only a few of those years were productive. Between 1859 and 1864, the mine produced 9,756 tons of copper, some of high quality.

The main shaft was Engine Shaft, later joined by New Shaft. By 1859, Engine Shaft was sinking below the 90-fathom level, while New Shaft was sinking below the 70-fathom level. However, optimism waned as ore quantity and grades rapidly declined due to poor headings. By 1866, New Shaft reached the 120-fathom level, later to 140 fathoms, while Engine Shaft halted at the 110-fathom level without finding fresh ore. Financial difficulties escalated after New Shaft collapsed in 1871 between the 60-70 levels, affecting production further. The mine faced setbacks from flooding, with most work concentrated in shallower levels. Ultimately, East Wheal Basset never recovered from the collapse in New Shaft, leading to its stagnation. Although exploration continued among old workings, the company was wound up in 1885.

Total production included 13,132 tons of copper ore, 40 tons of black tin, and approximately 18,000 tons of tinstone.
