The reason so much of it has been mined from placers is that placer deposits are usually easier to locate than lode deposits. Equipment used in both roughing and cleaning may be used for scavenging, depending on the amount of tailings to be processed. Placer mining is a collection of mining methods that use water to separate valuable ore from the surrounding sediment. A mill site is a location of nonmineral land not contiguous to a vein or lode that you can use for activities reasonably incident to mineral development on, or production from, the unpatented or patented lode or placer claim with which it is associated.
