The user can select options at the time of purchase or add components in the field without obsoleting the components they may already have.
In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. The name is from the Spanish word placer, meaning "alluvial sand". Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush.

Historically, mercury was used extensively in placer gold mining in order to form mercurygold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Largescale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and smallscale gold mining (ASGM), often clandestine, gold prospecting.

Unlike hardrock mining, which extracts veins of precious minerals from solid rock, placer mining is the practice of separating heavily eroded minerals like gold from sand or gravel. The word placer is thought to have come from Catalan and Spanish, meaning a shoal or sand bar.
Successful gold mining is generally done in two steps: First is sampling or prospecting, ... Because we are limited as to how much gravel we can process as smallscale miners, ...

Gold mining is one of the most common uses for the staking of mining claims. In Alaska, state mining claims may be up to 160 acres ( km 2), and there is no distinction between lode or placer claims.
