Something a bit different from all the Slate/Lead mines that I have been in. After a 3hr drive there is the usual problem of trying to find the mine, I missed the path and ended up walking straight up the incline. Using OS maps on my phone I ended up walking cross country on a steep hill. The thing was a sulphur mine is you smell it before you see it.
History
The first reference to Cae Coch is in 1607 by John Wynn that refers to a store of Brimstone which may be dug for a small charge. With the rise of alkali manufacturing after 1820 the mine became a lot more prosperous and was purchased by Thompson + Hill of Liverpool.
The first load of pyrites was ready by 1821, a mere 100 tons dug out by hand. For the next 10 years or so there was a steady 20 tons per month which was shipped directly to Liverpool.
In 1851 the mine was transferred to a new company and production was ramped up to over 1000 tons per year until 1856 where a collapse stopped work for a short period of time, for the next few years they could only work at half capacity. During the american civil war a good years production was 17,000 tons with up to 32 men.
By 1895 the mine had produced a total of 81,634 tons of pyrites.
In WW1 the mine was reopened to gather the materials used for ammunition, a crushing mill and aerial ropeway was also installed. From Jan - Dec 1918 15,951 tons were removed, just over half of the total output in the UK. The mine was opened for a few months in WW2 but due to lack of available labour and inconsistencies in the rock work was halted and the mine was abandoned.

There is some interesting bacteria in the some of the very acidic pools and some great colors. There is supposed to be blood red pools at the bottom but I didn't venture that far down.
