Method and apparatus for creating a planar cavern

A method for forming a planar cavern, comprising:

• drilling a first bore, wherein the first bore extends from a first access point to a resource deposit, and wherein the first bore extends through at least a portion of the resource deposit;
• drilling a second bore, wherein the second bore extends from a second access point to the resource deposit, wherein the second bore intercepts the first bore to form a continuous bore with a first end at the first access point and a second end at the second access point, and wherein at least one of the first bore and the second bore includes a first curve;
• towing a sawing assembly through the continuous bore, wherein a first end of the sawing assembly extends from the first access point, and wherein a second end of the sawing assembly extends from the second access point;
• placing a solvent in contact with the resource deposit through the continuous bore;
• moving the sawing assembly relative to the continuous bore, wherein moving the sawing assembly relative to the continuous bore forms a planar cavern, and wherein moving the sawing assembly is performed at least partially while the solvent is in contact with the resource deposit.
