I found one datolite nodule while looking for the rare
agates with copper inclusions in August 2005, and I came back to the same
place and found more in August 2006. As of August 2007, I did some digging
in an attempt to locate the source of datolites out of hope that I might
find larger datolites, and all I found are 15 tiny datolites. All
datolites found at the Wolverine Mine are very enriched in copper. The
tiny datolites still can be found from time to time at the Wolverine $#2
and there had been reports of datolites slightly bigger than an inch found
from the dumps.
