Abstract: This is a method to connect two or more drill holes, such as drill holes at distances of 2,000 to 5,000 feet or more apart, for the purpose of producing soluble ores, such as sylvanite or carnallite, from thick, deep ore bodies or from thin, shallow ore bodies. The drill holes are connected utilizing a signal-sending device in an initial drill hole and a sigal-receiving device in a subsequent drill hole. A fluid is injected down one of the holes forcing the effluent from the other hole thus forming a mined-out corridor between the two holes. This procedure can then be repeated with subsequent, offset drill holes.
