The Who Cares (pointless entry) other rock mine did remind me of an interesting statistic.
That between 1845 and 1913 over 75 per cent of the £39,486,405 tin output of the region was derived from just 33 mines, all producing over £1/4 million each, and 65 per cent of its £26,184,962 copper output came from just 27 mines, all with a total production of over £1/4 million each. To a certain degree these tin and copper producers were synonymous, eight mines appearing in both lists. Six of these eight copper and tin producers had a total value of output in excess of £1 million and, together with five other mines -all with an output of copper or tin of over £1 million -- they accounted for 42 per cent of the combined £65,671,367 of copper and tin produced in this region during the period by more than 1,750 mines. This "big eleven" of copper and tin producers is:
Dolcoath
Carn Brea & Tincroft
Devon Great Consuls
East Pool & Agar
Basset
Levant
Grenville
South Caradon
Phoenix
West Basset
Batallack.

A bit like Aditnow contributors. There is a small number of heavy contributors, and most have only added a few entries. But, the site would be a dull and pointless place without them. How boring the UK would be without its countless small and mostly unproductive mines ! :thumbsup:

'Ere. Who you callin' unproductive ? 😉

Umm.... I thought long and hard about this post, for fear of upsetting someone. 😉

I'm not upset Peter. Just couldn't resist the open goal !

I'm not sure that high numbers of posts is necessarily a sign of productivity..... :devil:

A bit like the many mines with huge amounts of development and minimal mineral output.

Chris.

Here, I can assure you that I am currently spending much more time adding to the database than posting dross in the forum (unlike a certain other forum I could mention 😞 )

I'm not upset!
One day, when I've nothing to do, I'm going to go through all the pictures on Aditnow.....

That would be me then :lol:

On the subject of contributors, I've said it before and doubtless I'll say it again. I'm continually amazed at both the goodwill around in terms of the time spent adding to the database and the quality and quantity of information that comes to light.

A quick check on the contributors http://www.aditnow.co.uk/contributors/  page says that 181 separate people have added mines, photos or documents! That's a lot of people adding things :thumbsup:

No, I meant me in UKC ! ::)

No, I meant me in UKC ! ::)

Wash your mouth out with carbolic soap three times Peter! 😉

That list of Tin and Copper producers seems to have missed Tresavean. A big copper producer in the 18th century and then a huge producer of tin in the 19th century. Figures in the millions of ££££s in both periods.

---

You're right there Roy I'd like to know where that (well informed?) list came from. Also what about Conslidated & United?

---

I would have thought Fowey Consols and the United Mines/Great Consolidated produced more copper during that period than Tresavean.

Roy, the figures in the original post were specifically between 1845-1913. The reason for this is because they came from the the official Mineral Statistics of the United Kingdom that was published annually. They were taken from an article by Roger Burt "Arsenic-Its Significance for the Survival of South Western Metal Mining in the late Nineteenth Century and Early Twentieth Century. Journal of the Trevithick Society.
