Abstract: A lithological displacement of an underground evaporite mineral stratum from an underlying non-evaporite stratum comprising the application of a lifting hydraulic pressure of a fluid at a weak interface between the strata, resulting in lifting the overburden above the interface, separating the evaporite stratum from the underlying non-evaporite stratum and thus forming a mineral free-surface. The lifting hydraulic pressure is greater than the overburden pressure. The formed mineral free-surface is accessible for dissolution by a solvent. The fluid used for lifting may comprise a solvent suitable to dissolve the mineral. The evaporite mineral stratum preferably comprises trona, nahcolite, wegscheiderite, or combinations thereof.
