Here in Sweden there is a coppermine Viscaria (some 10 k's from Kiruna
ironmine). That was found with help of a small arctic(?) flower with the
latin name Viscaria something. I have a vauge memory that Greenland 
Geological Survey (Vaster Farimaggade ??, Copenhagen, Denmark), were
using differents biological indicators, during a period in the mid-80:ies,
as well as some of the other nordic geo-surveys. Since I left geoscience 
at that time, my recollection is a bit blurred concerning bio-prospecting.

But You'll should be able to find people within the nordic geo-surveys,
try postmaster@sgu.se to see if they can forward any inquiries. GGU is
to my knowledge not on the net, specially if they have moved up to Greenland
during the last 2 years.
