The disclosure provides methods and systems for recovering a target mineral from a mineral-bearing deposit. One or more first wells and one or more second wells are drilled into the deposit, each well having a substantially vertical section and a substantially horizontal section, the horizontal section of the second wells located above the horizontal section of the first wells. At least one channel from the horizontal section of each first well toward the horizontal section of the second wells is established. A fluid is injected into the deposit from the horizontal section of the first wells to form one or more slots. A brine is recovered from the horizontal section of the second wells, forming a cavity. A salt solution is then injected into the cavity from the horizontal section of the second wells and a target mineral-enriched solvent is recovered from the first wells.

An apparatus and method for extracting sand from an underground sandstone formation. The apparatus comprising: a conduit having an upper end and a lower end to engage a sandstone formation, a gas injection line to inject gas at an injection point, wherein the gas injected at the injection point generates a low pressure region at the lower end to draw a sand slurry from the sandstone formation, and a collection port proximate to the upper end of the conduit wherein the sand slurry in the conduit is to be removed. The method comprising: lowering a pipe and air injection line into a sandstone formation, injecting air into the pipe to create a low pressure region at a lower end of the pipe to draw a sand slurry from the formation, and collecting the sand slurry at a collection port.
