A group of specimens collected from the Bluebirds #1 Pocket, July 17, 2013.





Bluebirds Pocket Zone #1 – 2013 to 2014

After the end of the Penny’s Pocket zone in June, 2013, an exploration crosscut was driven to look for flats on the east side of the vein. After about 10 meters of tunnel a narrow, tube-like series of fluorite-containing flats were discovered. The zone headed to the north-west, paralleling the vein, and in 2013 and early 2014 a narrow tunnel was excavated by hand following it. This zone is called the Bluebirds Pocket Zone #1, and was named by Ian Jones to commemorate his home town football team, the Cardiff City Bluebirds being elevated to the Premier League. The zone, though narrow, was quite productive and a number of high quality specimens were recovered during that summer.

By June 2014, the tunnel along the flats had become too long to effectively work by hand, so it was decided to extent the main drift forward and intersect the flats where the hand-digging had left off. About this time, several bearings in the gearbox on our Eimco 12B decided to collapse, and the better part of a month was spent rebuilding it. Driving tunnel resumed in late July but when the end of the hand-dug tunnel was reached, it was found that the flats were pinching out, and only a few additional specimens were recovered.
