Abstract: 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.
