Well I've scanned what I have - four surface plots of Long Rake, with all the original shaft locations marked (most of which seem to have gone now), and the most easterly group of which must include Bird Mine, though none are labelled as such. This is before the road course was altered, so that will have to be born in mind, and the old Barmaster's map will resolve that - looking at it, it looks like Shaft '22'.
Also elevations of Shaft 'A', just to the west of Batham Pot, Shaft '4' to the east (which is Long Rake Founder), and shafts '8', '9' and '12' which are to the east of that - all those appear to have been backfilled now.
Also elevations of Bird and New Venture and Brunt mines. I'll email those over to you later.

Yes, scans of the original data would be great. Thanks...AR said:

Whilst i'm on, there are loads of mines mentioned in this excellent PDMHS document (p79 onwards) that aren't currently on the Master.

I've never heard of most of them! Does anyone have access to entrance coordinates for any? I've pulled all i can off AditNow already...

Check out Trevor Ford's article on the geology of the lead mines of the northern White Peak in the same issue, which is possibly even more useful, though it does contain a few small errors, but nothing serious. My paper copy of that edition is literally falling to pieces, I've read it that much.
That also contains a redrawn survey of the Dan Rose survey of 'Mosrake Head' from 1754, with the whopping great cavern ('Compas of the Oapnes') on the west cartgate. Sadly no scale, but still, much of it can be inferred from the vein bearings, and I'm sure I can get a decent overlay to fit on GoogleEath with a bit of work.
We should be able to get a set of fresh GPS locations for most of the extant shaft tops on the main section within a week. I'm sure we also surveyed Black Rock Mine, mentioned in Chris Heathcote's gazetteer as 'slightly more west of Chance' in the Hell Rake/Lambpart section - I certainly have photos, and that was approx. 50m deep at the lowest end.

Many of the mines in Bradwell liberty have been lost to sparring and quarrying; if you compare, say, the 1898 OS to Google Earth you see just how much has gone so although Chris has turned up a lot of names, in most cases we don't have much left to see. Still, if we can get some of the old surveys plugged into the master map it'll help fill in some of the gaps
I'll have a look next time I'm in the museum and see if I can get you another copy of 17:5, Phil! Either that, or get your old one ring-bound...

Bradda Symposium Sunday 3rd April
A big thanks to all that attended it made for a great day.
After registration some 28 delegates sat down to the first lecture of the day.
Proffessor John Gunn gave an in depth insight into the hydrology of the catchment. He explained that dye testing that was carried out in the past had shown some interesting results, some of which were surprising. For example the Castleton catchment is connected in some way to the Bradda catchment, testing undertaken in the Peak / Speedwel systems had shown up in the Bradda watercourses.
Second up was Sam T and Rob Eavis who gave a demonstration of the new survex database that they had constructed. This amazing piece of technology enables the user to see 3D surveys linked to surface terrain and enable the user to spin the whole picture from vertical to horizontal. The visual graphics projected put caves and mines into perspective i.e. the bottom of Raddlepits Mine is 93 metres higher than the last sump in Bagshawe cavern.
After lunch we had a splendid presentation from Mark Harwood who presented the results on some of his geophysics scans. These again were projected in 3D and used a similar format to the suvex database.
Surprisingly the none condutive beds contained within the karst at minus 90 metres at the bottom of Raddlepits Mine and dipping to the East are lined up with the beds that bagshawe Cavern is formed upon. Other results indicate that open voids were found.
Phil Wolstenholme and Martyn followed by giving an excellent slideshow of the phreatic chambers and mined passages in Raddlepits Mine.
Nick Williams then gave a short talk on insurance which went on to include by debate thoughts of access to the catchment.
Close
A thank you to Moose, Tony Marsden and others who interjected and provided additional information where pertinant.
Thanks also to Julie for the catering and to Wakker Woodall for doing the washing up.
All in all a great thought provoking day.
From the information presented my views have changed. I realise that for the last forty years I may have been looking in the wrong place for which I have searched.
Watch this space.
