Between 1800 and 1840, profits are said to have been up to £200,000.[6] In 1852, the mine was almalgamated with Poldice Mine and Carharrack Mine and worked as St Day United mine.[7] Throughout the 1970s and 1980s, the mine site was turned into large lagoons and used as a tip for two other nearby mines: Mount Wellington and Wheal Jane.[3][8][9]

The site was bought from Carnon Enterprises by Gwennap District Council for a price of £1 in 2002.[10] An investigation by the Environment Agency that concluded in 2007 found that soil near the mine had high levels of arsenic, copper and zinc contamination and by 2012, it was deemed too hazardous for human activity.[8][11]

The mine gains attention during dry spells when the lagoons dry up and leaving brightly coloured stains on the pit banks and bed.[12][13][14]

2014 murder

In 2014, a 72-year-old man from Falmouth died at the site after what was initially thought to be a cycling accident.[4][15] It was later found that the man had been murdered.[16] A 34-year-old was found guilty and sentenced to life and to serve at least 28 years[17]

gollark: Thus bad.
gollark: It does NOT allow random access.
gollark: Hmm, so, designoidal idea:- files have the following metadata: filename, last modified time, maybe permissions (I may not actually need this), size, checksum, flags (in case I need this later; probably just compression format?)- each version of a file in an archive has this metadata in front of it- when all the files in some set of data are archived, a header gets written to the end with all the file metadata plus positions- when backup is rerun, the system™️ just checks the last modified time of everything and sees if its local copies are newer, and if so appends them to the end; when it is done a new header is added containing all the files- when a backup needs to be extracted, it just reads the end, finds the latest versions and decompresses stuff at the right offsetThere are some important considerations here: it should be able to deal with damaged/partial files, encryption would be nice to have (it would probably work to just run it through authenticated AES-whatever when writing), adding new files shouldn't require tons of seeking, and it might be necessary to store backups on FAT32 disks so maybe it needs to be able of using multiple files somehow.
gollark: I have been pondering an osmarksarchiveformat™ because I dislike the existing ones somewhat. Specifically for backups and append-only-ish access. Thusly, thoughts on the design (crossposted from old esolangs)?
gollark: If you run too much current through beans they may vaporise/burn/etc.
