Rodwelder,
My advice would be to go take a few samples and pan them out. Have you heard of any gold in your area? From what I have heard, the gold in the midwest, is fairly small, so pan it out carefuly. Welcome to the forum!

Here is some info you may find useful...

Gold is not known to occur in minable deposits anywhere in Illinois, so prospecting essentially refers to recreational panning. Gold has never been mined in Illinois, not even as a by-product of other types of mining such as fluorite, zinc-lead, or sand and gravel.

Information about panning for gold is available at sites such as Mining Links

Two older, noncommercial reports of gold found in bedrock in Illinois may be credible:

1. A small amount of gold was reported in a couple of samples of geode-like quartz from a hand-dug shaft in dolomite in Stephenson County (Hersey, 1899), southeast of the Upper Mississippi Valley Zinc-Lead District;
2. A newspaper story (Peoria-Star Journal, Aug. 6, 1975) reported that, around 1900, small amounts of gold were recovered from a shaft in Bald Knob, a large hill in Union County. There is no evidence to back up the claim, but some of the limestone and chert bedrock in that region may have been silicified by low temperature hydrothermal waters, which might have deposited a little gold. However, tripoli and ganister have been mined in the areas of most intense alteration, and no gold or sulifide mineralization has been found.

All of the other reported occurrences of gold in Illinois are from unconsolidated surficial deposits including boulders containing gold, small amounts of gold found by panning heavy minerals from sand and gravel deposits, or in material transported south from areas of gold-bearing bedrock in Canada and deposited in Illinois during the Pleistocene (ice-age) by the action of continential glaciers and later reworked by streams and winds.

An unpublished report by J.E. Lamar (1968) of the Illinois State Geological Survey describes occurrences known at that time. For example, on page 20, item 6 records a reported gold find in Jackson County about 1925. Boulders collected from a field near Carbondale were said to have assayed $25 per ton. No additional gold bearing boulders were found.

I have panned a few minute flakes of gold, with considerable time and effort, from certain samples of glacial deposits, including:

1. the Sangamon River Valley in Macon County,
2. the Mississippi River Valley and a small tributary in Henderson County,
3. the Illinois River Valley in Fulton County,
4. the Spoon River Valley in Fulton County,
5. an outwash plain in McHenry County.

Wherever you consider panning for gold, you must respect others property rights and legal restrictions. In Illinois, you cannot file for "mineral claims" on public land. Most land is privately owned, and permission for nonmechanized digging, panning, collecting, etc. must always be obtained from landowners. A mechanized activity may require a mining permit or more, especially if surface water is involved.

According to the Land Management personnel of the Illinois Department of Natural Resources, Conservation Division, panning is forbidden by law on State land, such as parks. The only open federal land in Illinois is the Shawnee National Forest, where very small-scale panning by individuals with no more than a trowel and pan is allowed as long as it does not cause problems.

The ISGS is a research and service agency, not a regulatory one so you will need to contact the Illinois Department of Natural Resources, Office of Mines and Minerals for information about permits for mining or dredging:

Prospecting permits for forest land may be applied for from:

Forest Supervisor's Office
Shawnee National Forest
901 S. Commerical St.
Harrisburg, IL 62946


Other references concerning the occurrence of gold in Illinois include these:

* Hershey, O.H. 1899. The gold-bearing formation of Stephenson County, Illinois; The American Geologist, v. 24, p. 240-244.
* Klasner, J.S., T.M. Kehn, and R.M. Thompson. 1983. Mineral resource potential of the Burden Falls road less area, Pope County, Illinois; USGS, Miscellaneous Field Studies, Map FG-1565-6, Pamplet. - A trace of gold was reported in the spectrographic analyses of two panned stream-sediment samples.
* Lamar, J.E. 1968. Gold and diamond possibilities in Illinois: Illinois State Geological Survey, Manuscript 128, 21 pp.

In summary, it is possible to pan trace amounts of gold in certain favorable locations in Illinois, especially in glacial outwash deposits and in deposits of streams that are incised into glacial drift. However, the only chance of gold being produced economically in Illinois is probably as part of a byproduct heavy-mineral concentrate recovered during the excavation and processing of sand and gravel for construction aggregate products, and only then if ideal economic and geologic conditions exist.

Don't think too much, you'll create a problem that wasn't even there in the first place.

Rodwelder: Central Illinois might contain some very fine gold. Because Illinois is flat, the runoff is gradual [unlike the forces achieved in mountainous regions]. Thus, I'm guessing that the shale you reference takes a lot longer to wear down than shale out west. The last glaciation melted off about 10,000 years ago -- a rather brief geological span in the scheme of things. Some of the fine gold released from the melt may still remain lodged in the shale matrix of your creek bed. Getting it out in any quantity, though, likely will require a suction dredge, assuming your creek has sufficient water depth. But first a simple gold pan will serve to sample the concentrates lodged in the shale. Thus, first clear off the overburden to expose a decent portion of the shaley bottom. Then utilize a hand suction device to thoroughly clean out the exposed bedrock, saving the heavier material you suck up -- probably several gallons. Sift this stuff through a screening device [like a large kitchen sieve], tossing out the bigger stones and keeping only what will fit through the sieve. Then reduce this material to the very heaviest last gallon or so by simply running a garden hose into a plastic cement mixing tub [or similar tub or even a bucket tilted some what to allow outflow], taking care to keep the water flow sufficient such that the lighter stuff flows out of the tub along with the overflowing water, but that you do not blow out the potential gold particles. When you have succeeded in reducing down to where the remaining material is mostly black sands that jump to a magnet, you likely will have sufficient material to pan down. Panning is not that simple for a person who never has tried it. Refer to other threads throughout this forum that focus on panning techniques. i know it sounds like a lot of work because it is. Illinois gold is very, very fine -- like flour. In order to get a reliable test of your creek's gold content, though, you will have to run a fair volume, not just a random scoop of mud from your creek. Too bad this wasn't posted a few months ago. Jill & I were in Illinois and we could have stopped by to give you some pointers and/or use our dredge. Good luck!!!

Prospecting success, be it for HEARTS, TRUTH or GOLD, takes COURAGE and HONESTY to penetrate through the appearance of things, plus PATIENCE and FORTITUDE to work through the many layers of things of which both nature and human nature are composed.

thanks for the advice,when the weather warms up i will sample the shale is all exposed in the creek bottom so it should be easy to get so sample material,maybe ill get lucky and find some yellow,it would be a good hobby
