Ore stockpiles are constructed to store sufficient ore volume to run the mill for a continuous period and to provide a "blend" of ore to ensure consistent feed to the mill. The first stage is crushing and grinding where the ore is reduced down to individual grains to ensure that the uranium mineralization is exposed to the leaching agents.
