Detailed Mineral List:

'Apatite Group'
Reference: No reference listed
Bayldonite
Formula: PbCu3(AsO4)2(OH)2
Reference: No reference listed
Bismuth
Formula: Bi
Description: Cooper & Stanley (1990): Shaw (1970: 51-52) mentions [...] 'fine specimens of bismuth' from the Emerson vein."
Reference: Shaw, W.T. (1970) Mining in the Lake Counties. Dalesman Books, Kendal. [2nd edition 1975 incorporating minor changes].; Cooper, M.P. and Stanley, C.J.

Description: Kingsbury reference. Cooper & Stanley (1990): "As unusually pale, almost cream yellow, 'thin, fibrous-radiating aggregates in joints in white vein-quartz... almost certainly from the Emerson vein' (Kingsbury & Hartley, 1957).
