or 200000 tons in excess of the licence expiry
a bit like stone digger's bucket parked 57 feet in and 25 feet deep inside the area of an ancient monument?
no criminal, no insurance, no 3/4 mil £ digger
umm
my Th and thermal Pu suggestions are low carbon for the energy that could be harvested
i am not a nuke fan
the UK has enough Pu for about 300 yrs if it was under a kettle rather than in a safe as we can manage storage bunker
there are better ways
folk who can make machines work in a mine or quarry can make "clean machines"work
at the mo lithium is at a premium, plenty in kernow, mining by solution has issues, perhaps less than digging wormholes or strip mining
iirc over 100 named minerals just in the Botallack seams, they might need a bit of work to get them accessible
i knew the place and people before it was a heritage site, the Corpus Christy seam is barely explored and perhaps 10% exploited
imho if it is a rare mineral, gets some new pumps and head deep under St Just, it will be there when you find it
the Owl and Edward seams are the other direction
mining a rising and up and down slightly fractured seam, under rock and under the sea is not my idea of fun
the old boy i made friends with had some terrifying tales of firing and getting a wet surprise 3/4 of a mile towards america
for "rare" kernow is probably richer than the DRC
specifically, for lithium which might be last season's fashion before a new full scale pump mines are operational, kernow has loads of any element require(and perhaps a few we have not registered yet)
if you need an element look in kernow
well me hansom, one old to another
if you look into a wormhole anywhere on the planet, someone will be making pasties nearby |

Forcing something underground to force something out is exactly fracking,what if some of these elements get into the water table,not unlike the info that has come from the US fracking sites. |
to be brutal, if you saw the pretty colours of a derelict adit runoff deposition from solution or the stuff that was not target in the dumped spoil, kernow is a good place to mine by solution, if the target elements can be targetted and grabbed tidily
bulk lithium is a bit behind the demand curve, plausible though
the elements that are rare and are useful are just as common as tin silver arsenic and copper(and the odd bit of gold, but we never mention that)
in the past they have been recorded by science and ignored or shifted out of the way as waste rock
with coal there is one target of varied quality, elements
are a bit more varied
kernow has most of them, if they can be located and extracted without spreading the rest of them around it does make sense
magnets, electronics, batteries , what do you need
ask the piskies to find them, they will try to avoid or appease the tommyknockers
as i mentioned we have a splendid selection box
those are some of our minerals, there are many others still to be recorded as potential target ore for most of the periodic table
the lithium pump mine is a minor aspect of the things available for high tech clever "greenish" use
the DRC has minerals, kernow has more, dont try sending wagner to secure them
even the romans were rather polite to the piskies and "the crown" did a deal that everything except gold was ours and untaxed, nobody ever found any gold, so it was never an issue |

the places with the fascinating stuff are volcanic, ie hard rocks with intrusions of seems from extrusion of a variety of dry and wet magmas
the bits with the metamorphic and softer rocks are not a target for metals
google scholar is delightful, a bit light on cats playing tubas

not a bad start
re holes that close and the surface, i have felt a fairly strong eathquake from one about half a mile away and about a 250 ft down
When the earth stopped moving, i was about 15 vertical feet closer to the sea, the steepish slope i was on did not separate from the flatter bit above above fortunately, but the chunk that moved would tens of thousands of tons
the bit that did break to the surface was half a mile away (the pebble drop was a litte over 3 seconds and the thing got a very needed a stout fence at a respectful distance in a couple of days
fall through, not off, the landscape into a very old worm hole is not fun
the camera had less scratches and bruises than me
the tommyknockers can be lived with but they do get busy if nobody is still playing hide and seek with them
as a comparison with coal, at least the gas and dust dont explode and most of the time the rock matrix is fairly calm about reasonably sized holes, big chambers are quite rare and can be a bit moody after a couple of hundred years
the ancient ones near the surface and long forgotten climb a seam to near the surface ones do sinkhole a fair bit, drop shafts are often fairly stable although the old sticks and bit of spoil cap falls down quite a few Which surprises a few folk who did not know it was there
hydro extracting the soluble and interesting and nor removing the spoil and direct matrix to get at the interesting might suit that sort of geology
there are cathedrals of stuff, but the most interesting elements in this context are in rather tight seams
im not sure about the lithium plan, i reckon as i do not know that area well, the seams with the heavier metals are mostly in hard rock that has often been mined for millennia that could be an issue if there is breakthrough, but the virgin seems might be quite safe and tidy if it was done properly
i will try to find the patents, that is often educational

in some ways i am beginning to rather like the idea
it need not be by solution, but scoping what is easy to see as a survey would be a splendid data set
boots bags bottles ropes mass spectrometer
there is a lot to look at, but it would be a basic sampling task
ps the amethyst vein is delightful, i only took a tiny sample of non gem quality, an honour to be shown it as a big thank you for something i did for him
tis a bit of a secret as to where that is, i have no obligation to share it
best crystal one i found was on the spoil between botallack and porthereas , half a small geode with quartz crystals with bright ruby red side branches , pretty rock me hansom
kernow is a bit fierce but it ain't twfcitw, i am warming to the idea of specific mineral targetting for rare stuff in kernow, bulk stuff has often been a bit untidy, done tidily it is unlikely to add too much more to the historic legacy chemical challenges |
