Note: The prospecting pick will not detect quartz, surface copper or rock salt (not to be confused with Halite, which does show up in this propick mode). The prospecting pick only detects ores above a certain threshold. Players will occasionally find ore deposits in a region when the prospecting pick did not indicate the ores are present. Such 'undetected' occurrences are very rare.
