In placers, gold is associated with other dense or “heavy” minerals such as garnet, magnetite, ilmenite, and even diamonds. Gold is also found in conglomerates that are lithified placer deposits. Gold has been reported from a number of places in Wisconsin, but the known deposits are all small and not economically viable.
Most of the gold found prospecting in Wisconsin is very fine textured flour gold, brought down from Canada and deposited by glaciers. This glacial gold does not accumulate in large enough quantities to interest large mining companies, but recreational prospectors can find placer gold throughout the streams and rivers of Wisconsin.

The best places to find flour gold include areas of already discovered gold like Ashland, Bayfield, Clarke, Dane, Douglas, Dunn and other counties as listed by the University of Wisconsin (see References). Placer gold, found in streams and having rounded edges, comes from placer deposits or gold veins exposed because of erosion.
Wisconsin shares its coastline with two of the Great Lakes, Lake Superior and Lake Michigan. The state of Wisconsin is famous for its vast deposits of iron ore, but for rockhounds there are other minerals that are more interesting.
My Wisconsin Minerals. Wisconsin is not noted for many Gem Minerals. We do have a few old lead mines in the South Western part of the state.

Panning for gold in Wisconsin streams and rivers has long been a pleasant outdoor recreational activity for a small group of amateur prospectors. There are minor occurrences of placer gold (deposits concentrated by weathering and erosion) to be found in most Wisconsin counties, but it is almost always in the form of small “flour” gold ...
Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water, leaving only the harder rock in place. Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away.
The three main types of rock in the range were all formed eons ago. About 2.7 billion years ago, the continents as they currently exist were only beginning to take form, and the area that would become northern Wisconsin was underwater. Eruptions from submarine volcanoes created a layer of rock on the ocean floor.
Aaron Cavosie of the University of , and member of the NASA Astrobiology Institute Team at the University of Wisconsin, brought students to an impact site in Rock Elm, Wisconsin to ...

Associated Minerals: Placer gold invariably is accompanied by other heavy minerals, which comprise the black, white, or yellow concentrates found in the sluice box when cleaning up.Table 3 lists these minerals roughly in the order of their commonness. Some of the characteristics noted under Remarks apply chiefly to the minerals as they are found in sluice-box concentrates.
In appearance it resembles a dark syenite, but its occurrence as an eruptive, intrusive rock distinguishes it, as syenite is generally a metamorphic rock. The peaks of the Elk Mountains are, many of them, of diorite. Diorite or porphyrite is the so-called porphyry of Aspen, above the ore deposits. QUARTZ PORPHYRIES:
Where to Sell Gold for Prospectors: Panned Nuggets, Flakes, Dust. Most people who get involved in amateur gold prospecting don’t ever find enough flakes or nuggets to worry about where to sell their gold. Recreational panning should be looked at as just that: recreation.

Different Types of Shiny Black Rock. Black rocks can be easily found in various places, including mountains and coastlines. However, a shiny black rock may not be that common. These types of rocks could be valuable gemstones or minerals that could be used for jewelries or they could also be made into a collection.
The average miner can instead purchase a CrazyCrusher manual rock crusher or an electric or gas powered rock crusher and get the gold out in smaller batches. Crushing rock to recover gold can be easier, faster, and much more profitable than prospecting in over-worked streams and rivers.
