In Situ Resource Recovery from Waste Repositories ...

A further variation of this approach is to excavate the material and place on a liner (as in heap leaching in mining), applying an extractant, collecting the pregnant liquor, removing the metals, and then recycling the extractant. Again, while this is technically ex situ, the nature of the leaching is in situ.

In-Situ Leaching & Borehole Mining - 911metallurgist.com

In situ leaching does not include dump or heap leaching where the ore is blasted and/or dug and placed in areas specially prepared for leaching, but is reserved for the process where chemical solutions are circulated through the ore body. Although the ore may be blasted to increase permeability for in situ leaching, it is not transported.
