It's simple yet effective design made it a valuable tool for the early prospectors to process ore on location, without having to transport tons of material to a stamp mill. Arrastras were designed to extract the valuable gold or silver that was locked in host material. Unlike placer mining, gold that is mined from lode sources require.
