Placer Mining is the most common form of mining, it involves mining gold that has been washed away from it’s motherlode (or source) and deposited in small cracks, holes, or sand bars in the mainstream of a river. It almost always involves the use of water in some way or another. Placer mining tools generally include the rocker box, sluice, dredge, highbanker, shaker table, drywasher, and always the pan. Placer Claims are 20 acres, and many modern miners have their own placer claim.

A prospect could be a hope for or anticipation of making a profit in mining. It can also mean to search for gold. Another definition can state it as meaning a place where a mineral deposit is sought or found.
