Output
Before its first closure in 1788, Dolcoath was estimated to have produced tin and copper valued at least £1,250,000. Of this, £450,000 was due to copper production between 1740 and 1777. From 1799 to its final closure in 1920 its total production of minerals was valued at over £9 million - this included arsenic, silver and other minerals.
From 1853, when the first dividend on tin was paid, the mine produced over 100,000 tons of black tin. This was far in excess of the production of any other mine in Cornwall. In 1896 the mine was yielding 80 pounds of black tin per ton of rock lifted, but this gradually declined to 30 pounds by 1915 which level was maintained until the mine closed.
Because of its success, the mine paid frequent dividends to its shareholders, and its shares, which were nicknamed 'Dollies', were among the most sought-after of the industry.

Famous quotes containing the word output:
“Lizzie Borden took an axe
And gave her mother forty whacks;
When she saw what she had done,
She gave her father forty-one.”
—Anonymous. Late 19th century ballad.
The quatrain refers to the famous case of Lizzie Borden, tried for the murder of her father and stepmother on Aug. 4, 1892, in Fall River, Massachusetts. Though she was found innocent, there were many who contested the verdict, occasioning a prodigious output of articles and books, including, most recently, Frank Spiering’s Lizzie (1985)
