For the above projects see nae.net.au/

Lochinver is evidently the Canonbie coalfield on the Scottish border, probably the one potential large and hardly worked coalfield in the UK.

Not suprised Redmoor has been taken up again

It's interesting to note that the Redmoor exploration licence covers 23 square Km - I wonder how far that extends.

I wonder if anyone has got their eye on Prince of Wales.

Interesting times indeed.

Redmoor and Mulberry pits are both decent prospects, Im sure Wolf will be looking into them once Hemerdon is up and running, makes sense once their mill is in place

Cligga is a similar geological deposit to Hemerdon.

It's also pretty significant and has permission in date, (so I gather) Although I don't imagine the lesser spotted newt will be too happy, as well as the yellow admiral butterfly, as well as those hairy vegetarian women.

There tends to be a lot of talk about Cligga, if it does ever get going again it'll have to be open cast, Crofty have a head start in that all their infrastructure is in place for development and they are still going to have significant issues due to mining amongst old workings, dont see why anyone would bother with Cligga.
What are the chances of getting approval to open cast there...the only similar working site I can think of is West of England quarry (Colas) would be interesting to know what approvals they have to have

they get aggregate out by sea, Cligga could have thay going for it I suppose

I imagine the exploration licence covers the area of the former Lord Ashburton's estates, (Baring family of Baring's Bank). According to SWCM management these mineral rights were purchased by the widow of a deceased mining engineer in the 1930's, with the hope of establishing a mine in memory of her husband.
Really regarding any future prospects at Prince of Wales, these must be minor compared with Redmoor.
To give some idea of the significance of Redmoor, the SVM zone discovered in the early 1980's was shown by intensive drilling to be similar in size & combinedSn/W grade to figures for Hemerdon at that time. However only this was just the quoted results for the investigated section, I understand the limits had not been proved either in depth or east (under Kit Hill) or west. It differs from Hemerdon in being largely sediment hosted, richer in Sn & poorer in W, and containing significant copper silver & zinc. The grades quoted for the investigated section suggest a tin content for that bit far exceeding all previous production from east Cornwall, a similar tonnage of wolfram, & copper more than twice that of the total production of DGC.
For the bulk of this to be worked could really be by open pit, which would result in the disappearance of the Kelly Bray
area. Not suprisingly, SWCM's plans were for an underground mine concentrating on the richer sections of the zone. this would still have been low grade & the largest mine in Cornwall in terms of crude ore tonnage.
Intersestingly although this mineralisation seems to have been unknwon to 19thC mines in the areas, SWCM did find remains of ancient workings along the back of this zone in trial pits they sank.

A chap from NAE was on Spotlight (local news programme) tonight talking about Redmoor. They are looking at a ten year timescale.

Ref Cligga - From what I understand, the plan is to extend the drive on 5 level - curiously there is no 4 level - and explore by diamond drilling.
CTML drilled a number of holes from a chamber down on 5 level in the late 1980's.
I have a small plan (somewhere) showing the number of holes and angles they were drilled at; no values stated though.
Even though the shaft is close to the sea, water ingress was extremely low and acidity was negligible. This has to be a big plus for this location, low waste management costs are very attractive.

It's worth reading this if you are interested in the Cligga area.
O.K. some of it does read like it was designed to attract prospectors and adventurers (Bal Selling), but generally the info is pretty sound.

It makes you wonder about the rest of the area. I wonder if there is any tin under Perran St George. It was exceedingly rich for copper and is pretty close to the granite. You've also got prudence and no doubt, whatever is offshore.

Anything which happened in the 20th century seems to be short on plans and short on discussion. Clearly there is a requirement for this information to be stored. I wonder who's got it. For instance Wheal Vlow.

Redmoor is interesting. Surely they can't be contemplating pumping that lot out? They had a load of fair sized engines up there for a good reason...

Roy, I think the reason there is no 4 level will be because it was driven out under the sea also they probably wanted to see how things were that little bit deeper, this was done by Geevor in the mid 1960s, it was a disappointment. 9000 samples later and still people are considering it!

Cligga:
There seems to have been rumours about something happening here for quite a few years now, but nothing more than that that I have come across. Presumably an exploration licence from the Duchy would be forerunner to anything happening. Also no sign of anything on the planning front, if old planning permissions still exist presumably they would have to go through the review process.
Apparently this site is one of the most significant bat sites in the county, that would have to be taken into account. It would be interesting to see if that was the case at the time of the operations in the 1960's and 70's. As far as I am aware the work in the 1970's by the then owners of Mount Wellington was limited, most recent work was in the 1960's by a consortium headed by Geevor. As far as I can see they were realy interested in specific targets, viz further development in depth of the zones worked in the 1940's, and diamond drilling for extensions of some of the copper lodes, with as Geoff said disapointing results. There is of course a whole sea bed full of further possible exploration targets, but it is perhaps difficult to define what those targets would be.
Re South Crofty, there was an excellent presentation to the Trevithick Society in Liskeard by the management a few months ago, which really should dispel any myths of "secrecy" for those who were there.

There is apparently a signed agreement between the 'interested party' and the Duchy, giving certain permissions. The finer details are subject to a non disclosure agreement; the interest is from a foreign source and that's as much as I know.
As for the no 4 level business, the section I have shows five level (and named as such) at the same horizon you would expect to see 4 level. It didn't make any sense to me when I first saw it, and it still doesn't now. 😞
