Because tungsten minerals are heavy, exploration can be done using stream sediment samples. Prospectors looking for gold have found scheelite or wolframite in their placer concentrates, and in some cases this has led them to make important tungsten finds. Perception of Mining vs.
Reality May Many modern mining companies have taken to making a special effort to ensure the goods and services they need are supplied as much as possible out of the local economy. The discovery was accidental as the operator was searching for strata-bound copper deposits. Common thought is the switchback slows the velocity of the rushing water and gold drops out from the cut bank to a fill gravel bar within or below the switchback.

I am not going to disregard that model; however, I hope to improve upon it. The placer deposits of Utah occur in two distinct types of environments.

These are 1 placers found adjacent to, and derived from, gold, silver and base-metal deposits; and 2 placers found in major rivers and derived from unknown, distant sources.

What are the main components that I should look for? Is it possible to pick gold out from other sediments by hand?
