In-situ mining is the "removal of the valuable components of a mineral deposit without physical extraction of the rock" (Bates and Jackson, 1987). In-situ leaching is a type of in-situ mining in which metals or minerals are leached from rocks by aqueous solutions, a hydrometallurgical process (American Geological Institute, 1997).

Mineral extraction operations locate where mineral deposits exist. The location of such mineral resources is dependent on nature (specifically geology) versus land use or zoning districts. Mineral deposits having potential for extraction are usually located in land zoned agricultural (A1-EX, A-1, and A-2).

In Benguet province, a group of miners have been using the mercury-free gravity-borax method (GBM) for gold extraction for decades. This method basically requires the same equipment as the amalgamation methods. However, after the rod milling, an ore concentrate holding the heavy minerals is produced by using a launder (gold sluice) and a gold washing pan.

Surface mining, which includes strip mining, open-pit mining, and mountaintop removal, removes soil and rock from on top of the mineral deposit. It may begin as soon as the pre-development steps are complete. Underground mining uses shafts and tunnels to access deeply-buried mineral deposits, while the overlying rock is left in place.
