Gold Prospector (GPAA) magazine Jan/Feb 2010 issue has an article on Hoosier nuggets. Nobody wants to share the location to find them, but shows what Indiana nuggets look like. Shows a selection totalling over 1 ounce of nuggets, some nearly the size of a dime. The author got in 4 hours dredging bedrock, 1/3 ounce pickers, small nuggets with a 2.5" dredge.
That is the secret...to find gold in Indiana, you must find out where bedrock is first. The gold matches ancient deposits of Ontario, Canada. It is about 22K and much better than gold from the western United States. But, I talked to someone who found flour gold in Bristol...a town in NE Indiana. The problem is finding the bedrock which doesn't really exist (does it?) in the north part of the state.
You find gravel deposits left by glaciers from South Bend to Ft Wayne, down to Kokomo, IN. Just draw lines between the cities...it is a glacial deposit triangle. There is a rock found throughout this area. I sent a sample to an assayer, who does assays for gold mines at Ridgecrest, CA. The assay was Glaucophane, a mineral common in places jadeite is found, many places in Japan and certain costal ranges on the western US coast. It appears when wet in overcast sky weather a grayish bluegreen. Follow this mineral, I even found it in N Kokomo. A lot of white quartz rocks, flinty chert, bright pink granites. usually in these deposits also.
