IMA Mine
View of Mount Borah, Idaho's highest peak at 12,662 feet. |
This molybdenum-tungsten project in east-central Idaho, USA includes 21 patented mining claims, covering approximately 376 acres, and four parcels of adjacent land totaling approximately 216 acres. Gentor's work has concentrated on exploration and development of a large, molybdenum bearing intrusive located below the existing mine workings.
The IMA Mine was an underground operation which closed in 1957. Prior to its closure, it was the fifth largest US source of tungsten, having produced over 500,000 tons of ore between 1937 and 1952 (Engineering & Mining Journal Vol. 154.No.7). The lowest level of the IMA Mine intersects the top of a molybdenum-bearing intrusive just above the canyon floor.

During 1960, American Metals Climax, Inc. ("Amax") drilled two holes into the intrusive from underground. Hole #1 intersected 133 feet of 0.075% MoS2, entered a barren section, then intersected 456 feet of 0.129% MoS2. Hole #2 intersected 230 feet of 0.193% MoS2 in the first mineralized section, but drilling ceased before intersecting a second mineralized section.
Inspiration Development Corporation ("Inspiration"), a subsidiary of Anglo-American Corporation, entered into agreements relating to the property in 1978 and spent an estimated $2 million over the next 3 years, concentrating on the tungsten potential. Work by Inspiration included drilling 16,700 feet from underground and surface, rehabilitation of the "D" level, (located 670 feet above the canyon floor) and the completion of "basic underground development for extraction" of the tungsten ore. Inspiration Hole #ID 16, drilled into the intrusive from adjacent ground approximately 1,000 feet from the Amax Hole #1, intersected 355 feet of 0.150% MoS2 and 0.09% WO3.
