Sampling Placer Deposits by Drilling

The sampling of placer deposits by drilling or, more precisely, drive-pipe sampling, is discussed in detail by Janin. He states that the Keystone no. 3 traction machine is used generally in California. The usual casing is 6 inches inside diameter and 3/8 inch thick, in 5- to 7-foot sections. Drilling without casing is not good practice, and high values in a hole so drilled cannot be accepted

Removing Fine Placer Gold from Black Sands

They basically work like a gold pan, retaining fine gold with gravity and allowing lighter materials to wash out. 3. Gold Cube – These separate out the gold in a very similar fashion as the sluices that are used in the beginning of the prospecting (if that is a prospectors method of choice) but these use smaller ‘riffles’ than a normal sluice does and there is also a lot less water used

This is particularly true if the gold is fine - it is better to cleanup more often than to lose gold. In fact, a sample from the output of the sluice should be panned out multiple times per day to see if gold is being lost; if digging moves into an area with more fine gold, the sluice should be adjusted to capture it.
