Mining Methods. There are four key stages of work involved in mining for minerals. These include: 3415, 3416 Prospecting – The purpose of this stage is to identify areas that are likely to contain mineral deposits. The work includes geological, geochemical and geophysical surveys ( seismic surveying), aerial surveys, including the taking of samples by lowimpact mechanical methods.

Likely mine sites were identified by surface finds. Ore was extracted and removed by iron hand tools, and lifted up the shaft using a rope. In the 16th century, miners were still using firesetting and wooden trays. In 1600 years, mining technology progressed very little beyond the Roman practices.

LKAB is using a variation of conventional prospecting drilling to search for new orebodies and secure reserves for the future.
