The underground geology of part of the Carrock Tungsten Mine, Caldbeck Fells

This report summarises underground geological mapping undertaken in the disused Carrock Tungsten Mine in May 2013 and the subsequent analysis of water and tungsten vein samples that were collected during the mapping. The mapping, focussed on workings that post-date a previous report on the geology published while the mine was still active, confirms the underground geology previously reported. Analysis of both surface stream and underground water samples collected during the mapping show that arsenic levels exceed WHO guidelines for drinking water in all samples collected. No other elements exceed the WHO guidelines.
