Abstract
The method comprises drilling alternate rows of vertical injection and recovery wells to the depth of an aquiferous mineral-bearing stratum. Two horizontal branches are drilled at the bottom of each injection and recovery well. The horizontal branches are parallel to each other and lie within the mineral-bearing stratum. Leachant fluid is pumped under pressure into the injection wells to dissolve the minerals contained in the stratum. Leachant fluid containing the dissolved minerals is pumped out through the recovery wells.
