Wow! Some land owner is missing out. Blue quartz of that quality is highly marketable. If there are other colorfast colors of almost pure silica, that nine would be worth more than a goldmine on today's lapidary market....Mel

It sounds like they were just getting square/layered rock Mel. Not really pursuing the lapidary value.

almost looks like it may be "quartzite" that is usable in the countertop industry.

I dunno - chrome is green Cobalt is blue. A quick look here indicates there are many ways to make blue. |

Highly doubt it's blue quartz; looks more like blue staining or veining, most likely a bit of copper producing azurite stains.
Love the documentation of old, abandoned mines, but not sure it's something that ought to be publicized, that is not a safe place to be playing around.

I was curious of a coating. Or stain. Cartersville Georgia USA has many colors from so many metals in the area. Not so much blue though.
No not safe at all. Natural caves ok, man made not.

Wow!
This place looks truly amazing. The various colors of the stone in the mine are outstanding. Thanks for sharing this!
It's amazing how hard people will work to obtain such raw materials; think about the intense labor it took to create that mine and then "harvest" from it. It reminds me of Thousand Steps (see >http://www.summitpost.org/jacks-mountain-1000-steps/153845<) in Pa. where the workers, each work-day, climbed up a mountainside over 1,000+ rough-set, stone steps to get to orthoquartzite quarries, and then had to climb back down at the end of each work-day. This rock was used for the same purpose as the rock from that mine in Wales... to create heat resistant brick.

I think it's possibly blue quartz(ite) This image is blue quartzite. It represents a slab 2cm think and approximately 3 meters by 1.5 meters in area.  I admit is comes from the wrong continent but it is quartz (I have touched similar material) it is BLUE. |
