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 crushing to extract the gold from rock. The basic design generally used two large flat stones that were dragged around a circular pit made from flat stones.

Next, blasting occurs to break down the rock making it easier to move. A fleet of excavators mine designated ore areas and move the gold containing ore to stockpiles. The stockpiles containing the ore will be processed to extract the gold. Trucks move waste to a waste rock stack, which can be rehabilitated to fill previously mined areas.
