Small samples of soil are taken on an expansive grid to identify parts per billion of gold. This method can also be used when geologists want to sample the top of bedrock, which can be 20 or 30 metres below the surface. A diagram based on pXRF sampling at Mitire Mining's Bateman's Project in NSW, showing areas of elevated silver.

The 3 most common commercial biomining processes are: 1. Slope Leaching. Fine ore is kept in a large, slopeshaped dump. During slope leaching, a water solution made of inoculum is continuously sprayed over the ore. After that, the leach liquor (or remaining liquid) is gathered at the bottom and processed for supplemental metal recovery. 2.
