Bottle Hill Mine is situated just over two miles northeast of Plympton.

 Otherwise known as Old Bottle Hill Mine,

 due to the fact that it dates from the early 1700's,

 the mine worked four E-W tin and copper lodes, known as North Lode (Blanchard's), Main Lode, Buckinghouse (Caunter) Lode and South Lode. It also worked a N-S lead bearing crosscourse.

Production records report that early production was tin and that between 1823 and 1835 - 1800 tons of 4.75% copper ore was raised. Between 1837-39 and 1852-85 - 640 tons of black tin was produced. In the period 1856 to 1875 - 200 tons copper ore was raised. In addition the mine produced 30 tons arsenopyrite and 13 tons of arsenic.Drakelands Mine

The Drakelands Mine is a recently constructed world-class tungsten and tin mine located in the United Kingdom and it is one of only two mines outside of China with production capacity greater than 3,000tpa tungsten concentrate.

Location


Drakelands Mine is located near the village of Hemerdon in the UK in an existing mining area and adjacent to operating China clay mines. The City of Plymouth is only 10 kilometres away, providing the Mine with excellent transport links and power and water infrastructure. Plymouth has a large naval base and university providing strong ancillary services and support for the Mine. The location of the Drakelands Mine enables Wolf to recruit and retain a talented and stable workforce, who generally live in the local area.

Processing

The Drakelands processing plant produces tungsten and tin concentrates. Ore is fed into the processing plant where it is crushed and ground to liberate the minerals from the rock, and then separated and upgraded using various gravity, heavy media, flotation and magnetic processes.


The processing plant will produce approximately 5,000t tungsten concentrate and 1,000t tin concentrate each year  – equivalent to 1 truck a day exported to customers in Europe, USA and Asia.

Lower Hooksbury Wood

Industrial Archaeological Features Industrial activity finds its most striking manifestation in a very fine example of medieval and later tin working. It takes the form of an openwork over one km. long from east to west and up to 250m. wide (L). The worked area has scarped sides up to 6m. deep and it is filled with tinners’ shafts, trial pits, and waste heaps (not depicted in detail on this overlay). The west end of the openwork runs into Lower Hooksbury Wood, where it is not visible on air photographs. It is served by numerous leats running in from north and south and the actual remains of some mining buildings appear to survive in places, particularly at Wheal Florence (M) where the remains of a whim platform can also be recorded. A very unusual alignment of pits (N), presumably derives from mineral prospecting but their date and specific function are unknown.
