Tunnel builders at the Gotthard come across crystals
The Uri Minerals Supervision salvaged several hundred kilograms of crystal rock from a chasm that came to light during blasting work for the second Gotthard tube. Experts speak of a remarkable find.
A pink fluorite recovered from the tunnel of the 2nd Gotthard tube. The transparency of the pink colored crystal is outstanding.
The find spot is around 300 meters from the tunnel entrance in the ceiling area. The boss of the blasting responded in an exemplary manner and immediately summoned the cantonal mineral supervisory authority, the Uri construction department announced on Friday.
At the end of September, they encountered numerous quartz specimens, apophyllites and pink fluorites. The latter in particular were of outstanding quality. This is one of the best finds in Switzerland for years, geologist Peter Amacher is quoted as saying by the Uri Minerals Inspectorate.
For around 24 hours, he and his team recovered several hundred kilograms of rock with the help of a lifting platform. Amacher had already taken over mineral supervision during the construction of the SBB power plant in Amsteg and the Gotthard base tunnel. In 2011 he published the book “NEAT minerals – crystal treasures deep in the mountain”.
The stones that have now been found belong to the canton of Uri. The finds are currently being cleaned, sorted, recorded and assessed for their material value. The most beautiful ones go into an exhibition.
