• Whats on the Box?


    Well it would appear that Rhino is on the box, in Box, thats right yet another trip report!!!!!

    After reports that some kind chavs had kicked over all the robots in box a tam was assembled by Darkplaces to go and rebuild, as a few of the CBC were also local we joined in to assist and help tidy the place back up and have a quick wander round at the same time, as its been a few years since some of us have been there

    After a short walk to Backdoor the assembled nutcases headed for cathedral and then, after a slight interlude waiting on a 4 legged companion that had gone off on his own, onto the robots we went.
    Upon arriving we found a small group already starting the rebuild process as they had seen the request for help and headed in earlier but this was the devistation


    So a plan was rapidly formed to get things back together and create something special, I give to you….



    no not really, but i am proud of it 😀

    Anyway something special was created WP_20131217_20_56_21_Pro

    Box has a Dalek again

    Well after all the rebuilding it was a quick march back to backdoor and into the quarrymans for a well earned pint, Job Done!

  • Polgooth

    Jamie C and I visited Polgooth mine, I used to ride bikes around the spoil heaps when I was younger with the landowners grandson but had never really paid any interest to the workings back then.

    We were pointed in the direction of the landowner who is fascinated by the site and was a great host, we were shown the North adit and old mine shop by her then invited in for a cup of tea. We were then shown two bulging folders containing research material. After a long chat we were pointed in the direction of her brother Brendon who lives in the old engine house, he pointed us in the direction of the adit behind his house and spoke of the previous attempts to open it. The first 15 metres IIRC is in poor rock and has fallen in, apparently beyond this point the rock is good and there is potential to dig through in… to further workings. The other side of the adit collapse apparently can be accessed via abseiling down an open shaft.

    I told him about the group and said that we would be interested in having a look, perhaps we could lend a hand and help him out?

  • Not so high line

    Last weekend a few of us decided to practice setting up a high line…. Because we can!

    We picked a local spot with some good trees for anchors and a stream for dunking.  We tried a couple of different reeve setups for raising and lowering.

    The English reeve – where the reeve line runs the whole length of the span.

    The Norwegian reeve – where the reeve line runs from one anchor and terminates at the kootenay.

    Norwegian Reeve

    For both of these systems we used twin 11mm HTP tracklines, the thought being that two tracklines adds an additional element of redundancy into the system.  For an added bit of excitement we tested the resilience of the system by failing one, and then both of the tracklines to see how the system reacted.

    Wet feet!!

    The system quickly equalises following the failure of a single trackline with the rider only dropping a short distance.

    The failure of both track lines causes the whole system to drop onto the control lines and reeve line (if an English reeve is used).  In this scenario the control lines were pulled taught prior to the failure, even still, the result is dramatic.

    The next move is to take this system to a more airy venue, and most likely, get extremely wet!



  • South Wales C*ving

    In late July 2013 the CBC’s Delta team made a daring raid into neighbouring territory.  The purpose of this mission was to gather intel on the strange un-Cornish like features known only as “caves”.

    Early Thursday morning, Mr Pat and Darren made their move over the border.  Arriving early afternoon they made a recky of the local area and opted to carry out a couple of dives in White Lady cave.


    Late afternoon reinforcements arrived in the form of Lady Roo and I, after a short “follow me” moment which closely resembled a scene from whacky races, Delta team was up to full strength and ready to make a full frontal assault on Town Drain Cave.  This proved to be a surprisingly interesting little cave which served as a good warm up for the late arrivals.


    A forward operating base was made at the campsite of the national show caves centre, after much sorting on kit, and many mosquito infused drinks, the day was at an end.

    The following morning was dry and sunny, perfect for the short hike to the entrance of Pwll Dwfn a couple of Km above the camp site on the edge of the Black Hills.  Pwll Dwfn proved to be an amazing pot hole, 110m deep over five pitches with some two dozen or so anchors in situ.  This was what we had travelled for!  Mr Pat took the lead rigging the various pitches as we travelled down through the massive tubes of the cave.  For me this was the highlight of our trip – proper vertical caving, vertical abseils, re-belays and deviations within the most amazing rock formations. Perfect.DSCF1990DSCF1995DSCF1996DSCF2003

    Once we returned to the campsite, Mr Pat and Darren made their way back to Kernow.

    The following day Roo and I ticked off Bridge Cave, Wills Hole and Dinas Cylica mine from the guide book before heading home on Sunday.

  • Code Name GFY

    Very near the village of St Agnes on the cliff tops, three of the black ops team swung into action.  Their goal was a recently opened shaft that shall be known “shaft 4b “, the mission was to plumb it’s depths . The collar was stone lined and a little loose so a deviation was banged in on the the first good rock encountered which gave a pretty good free hang . As the shaft was descended pockets of back filled stoping were passed.  At – 25m a huge post bridged the snug shaft ,about 1.2m x 1.3m ,and it gave us an opertunaty to get into a small level with only led on to a small quantity of stoping. After the level was investigated the shaft was dropped a further 30m to bottom . The bottom was a chamber created by 45 degree workings which was largely back filled . The area was pushed in one direction but didn’t yield anything of interest .The team exited the shaft and the site under the cover of darkness.

    Tea and medals were awarded on the teams return to CBC headquarters.


  • Lightening the Load – 9mm brown trouser ropes

    Often accused of over complication and undue health and safety, the CBC would like to shed some light on some of the labour saving choices we have been making.

    Now we all know carrying 50m of 11mm rope can be back breaking , not to mention the reduced pasty carrying capacity as a knock on affect.

    Over the last 24 months we have been lightening the load on occasion by using ropes of the sub 10mm nature. We have now used four different varieties and feel it’s time to review our choices.

    The four are:






    Firstly we are not in the slightest bit interested in CE marks standards etc. Strength ratings are also of little interest to us BUT if you are of cowardly Devonshire disposition the Sterling Canyontech excels are a rating of 27.1KN minimum breaking strain. We are more concerned how the rope performed over a period of time and by performance we were looking for; durability, knotability, handling through devices, ascending/descending, fashion(does it clash with our funky clothing).

    Sterling 9mm Superstatic. We have used this on big drops as well as small. We found the rope was the stiffest of the bunch and with time this aspect has increased but not to a level to cause nuisance. No problems with ascenders and a multiple of descender types have been used on it , all functioned reasonably. Little bounce was experienced on ascending/descending. The rope sheath seems reasonably abrasion resistant but after heavy use, not fast, has started to glaze.  Plus it’s available in a range of colours!

    Beal Spelenium 9.5mm Gold. We have been using this for well over two years for both big and small drops. The rope has only stiffened up a little and remains very knotable. The rope has dealt well with abrasion with its extra 0.5mm sucking up the punishment. The Spelenium excels in its interaction with devices, it really comes into its own when used in a Petzl Stop so descending is a pleasure. During ascent the rope offers very little bounce therefore a pleasant ride can be enjoyed.

    Gleistein Geostatic 9mm. We haven’t had this rope long and we tempted to buy it because it got a mention by a few retailers. Knotability and suppleness are currently excellent. Abrasion wise the rope isn’t fairing so well with areas of “fluff” appearing after a very few outings. Interaction with devices is nothing special, the rope runs very quickly through descenders so extra friction would be advised. The Gleistein does give a fairly bouncy ascent which combined with its not so good abrasion resistance requires careful rigging.

    Sterling Canyontech 9.5mm The Canyontech is the least supple of the bunch and this has worsened with use but this is not to a degree enough to cause problems. The Canyontech handles fairly well through devices both in ascent and descent . The rope is very abrasion resistant, it excels, due to its Technora sheath .In fact it is fairly heat resistant as well so should be considered for rapid descent. During ascent it does bounce a little. It comes in an olive drab colour which makes it a contender for covert operations.

    In a nutshell; It’s horses for courses, if you are doing short poorly rigged drops I would consider the Canyontech. If you doing long well rigged drops I would consider the Sterling super static. Anything in between, the Beal Spelenium Gold has got to be a good option. As for the Gleistein, I really don’t know why it is being marketed for underground use, OK it’s got its EN1891A so it performs like a thicker rope BUT there are much better ropes available and it is only pence cheaper than the Spelenium. Although I do like the orange colour it comes in…… Consider the Canyontech with its MBS is 27.1kn and you can hammer nails in with it. The Spelenium is weaker BUT what a pedigree and so little bounce!

    So less rope = more pasties.


    S&M wise the Beal offers a soft feel to tourniquets and bindings, you and your partner will also enjoy the luxurious solid gold colour ideal for most role play.

  • There’s a storm coming….

    Well wih the TV awash with warnings of impending doom due to a weather front forming in the atlantic what better place to be than wandering along clifftops in howling rain and wind heading into Cligga mine to have a wander around, as normal I was a bit late so had to catch everyone up but once in top level I caught up with the group including a few people new to joining us on our little underground adventures, Hi Hugo, Neil and Tracey,


    After dropping down one of the old internal ladderways we had a good wander round the middle level and a look at Contact Shaft in prep for some more exploits next weekend (Top Secret Shhhhhh!) and then progressed down through the big stope and onto bottom level for a wander round



    after a good look we headed out onto the beach to see the sea with some huge waves crashing in,


    after a quick bit of beach combing it was then a nice climb up the old miners path to the top where you could have been blown back down again if not too careful and time to get changed and head home, Cheers to Hugo and Pat for the pictures, can’t wait for next weeks 😀

  • Hallenbeagle has fallen

    it would seem that the only shaft left open on hallenbeagle mine has been capped and filled according to pictures recieved, it would appear this has been done without permission and with the possibilty that there are bats in the workings below, we previously showed pictures of the shaft that someone had attempted to hide and cover and earlier in the year but it would appear the diggers have moved in


    Hopefully will have more information soon, any local press that would like to take up the story of CCC ignoring thier own planning rules please get in touch and i will forward you to the relevant people

  • Surprise Discovery!!!!

    Well it seems some of the crew went for a plod round Wheal Luna today to have a look at some things and take a new chap(Hi Simon) on a quick trip. It would seem that whilst on this trip a troup of Latvian Cheerleaders decided to make an appearance and according to all that went underground they were so shocked and dumbfounded they didnt take any pictures, but to make up for this Roo decided to draw a sketch of where they found them and the perils of the journey, im not sure I 100% believe the story and i reckon someone just forgot to take a camera, anyway have a look at the picture and decide for yourselves.1174827_10153332149665640_2106698171_n

  • Corin’s diary from the CBC Minibash weekend

    My diary from Tuesday 10th Sept through to Mon 16th Sept.

    It’s my diary and it is all about mines, mine exploration and cars dying. So Tuesday I met Chris Phillips and Erica Gough at the Africa café in Betws y Coed. Off into the woods above Betws, park up and change into 5 mm wet suits and boots. Off down the hill to Cwm Maer Pool (recently made accessible); in 6 ft and it was neck deep water and knee deep ochre mud. Not warm. This went on for 300 yds then a good mile further in until a collapse, interesting and fragile mine very rarely seen. Weather dependent access.


    Then back to sunny Stoke I had left my chargers and sleeping bag behind. 40 minutes later the Ford Focus developed a high pitched scream, a loss of power and clouds of black smoke. I pulled over and got RACed home by 22:20. Argh I needed to be in Cornwall on Thursday, £1200 to get the car back on the road. Too much so I borrowed Marg’s car and stopped off at my twin brother’s in Redditch for a night. Food & a little drink and off to Ludgvan at midday.

    Arrived Thursday early evening and met up at Pat’s midday on Friday. Six of us (Pat, Claire, Mad Rab, Matthew, Talan and Corin) met up in the rain to do Cligga; a lovely tin mine full of golden granite and 2 cheerful pull throughs. Claire wore her SpongeBob Squarepants oncie and some very happy men’s underpants. The quote is on the website. Pat had very kindly left a little ‘new ground’ for us; so off Sq Pants went, guess what – it only went 20 feet. There was a level visible above, Pat & gang will be drilling at some point to access this level. A lovely cheerful and welcoming mine, some squeezy bits and a little crawling. Fun fun fun.

    looking for new ground-cligga

    Saturday was Rosevale day, every year we do at least a half day of hard graft in Rosevale. This year was no exception. Tony and gang had dug through a collapse that had then collapsed again, so we were tasked with removing the sludge. It was down on Level 2 and eight of us with 4 trugs and 2 kibbles moved 2 tons which was (4 trucks). We all took turns digging Claire, Scotty, Tony, Tom and Rab all laboured mightily in a narrow passage. One person at a time, the team dragged the trugs to the kibble which was lifted 30 ft with an electric pulley, tipped onto a truck (thanks Kim and Alan) and job down.
    We bought 45 doughnuts and only 5 were left by 18:00 – that’s 2 tons = 40 doughnuts among 8 people. Thank you Tony and Alan always fun to work with you.


    Sunday – Harveys North and a straight 280 ft free hang. Thank goodness for Pat, Kim, Paul and Talan the thought of SRTing up 280 ft was not attractive, CBC set up a lovely 4:1 haulage system. So down Scotty, Mad Rab, Claire and myself went. It was a long way and the patch of daylight was very small indeed. A lovely little mine – coffin sized hand cut passages, Claire and Scotty sped through and went off crystal hunting. Mad Rab spent time taking photos. Then he rigged up and using Graham’s excellent radios he booked a lift and off he went. We collected back at the platform; we were all coughing and Claire was feeling sick. The air was bad, whoops. I went up next and quickly we got Claire up. She surfaced and Pat had to look after her, her head and appetite were affected for 24 hours. Scotty was hauled out. It could have gone wrong. Lesson is ‘plan for possibly Bad Air’ – Bad air detector, especially when the exit is not fast. I had failed to anticipate.


    Scotty left for Shrewsbury after that, it was great to see him; after a tough year. Hope to see him soon and he stays well.


    Monday, Kim, Claire and I were still camping, Pat offered a trip into Lunar in the morning. Kim had to go to work so we three went off to Lunar. Newly opened (thanks to the CBC) this little beauty involved crawling (wear knee pads) and a pleasant SRT. The passages followed the lode, twisting and turning like an drunken rabbit . Leaping 8 feet and dropping at random (so it seemed). Pat had a dig at the far end, a little work and the draft was more noticeable; we popped back to Claire who had hurled herself into a 6 ins slot above back fill. She cleared about 20 ft along to a depth of about 15 ins. She was digging like a mole hurling rocks backwards towards Pat and myself; we had to keep the space behind her clear. When she finally emerged, the grin was full width.
    Clearly space for exploration and an excellent trip with crawls and a little squeeze or two. A very fine trip.

    Then onto the lovely A30, M5 and M6 everything seemed like 80 mile sections and they went on forever. Back home and it took 3 days to dry and sort the kit.

    So an excellent 4 days, massive thanks to Graham & Victoria Wall, Kim, Pat, Claire and Scotty, Talan, Paul and Bonny, Matthew and anyone else I have forgotten; sorry.

    Looking forward to next year already.
