History

American CuMo Mining Corporation

The CuMo Project deposit was first discovered by AMEX Exploration in 1963.

Originally staked by the Curwood Mining Company in 1968, the property was optioned by Midwest Oil Corporation in 1969. Between 1968 and 1972, Midwest drilled 8 (eight) holes totally 5,201 feet (162 meters) and did geological mapping, geophysical surveys and surface sampling. In 1973 AMAX exploration optioned the property from Midwest.

In late 1973 AMOCO absorbed Midwest Oil and became the joint venture partner with AMAX. Between 1973 and 1981 AMAX drilled 17 holes totaling 30,821 feet (9,394 meters), majority of the holes were large diameter diamond drill holes with three being reverse circulation holes.

The 1982, an AMAX computer generated, block model indicated a geological resource of 1.387 billion tons of 0.093% MoS2 at a 0.05% MoS2 cutoff, including a higher-grade core zone of 444 million tons of 0.135% MoS2 at a 0.10% MoS2 cutoff.

Several significant thick intersections of Molybdenum bearing mineralization were intersected. However, with the drop in Molybdenum prices to all-time lows, interest in the property waned.

In 1983 the property was returned to AMOCO who were in the process of divesting themselves of all mineral properties. As such the property was allowed to lapse.

In 1997, the property was staked by the CUMO Molybdenum Company. In 2004, this company optioned the property to Mosquito Consolidated Gold Mines Limited (currently Idaho Copper Corporation) at a very favorable price due to depressed metals markets.

As of December 31, 2022, a total of $52 million has been spent (2017 dollars) with a total of 37,094 meters (121,700 feet) in 68 holes having been completed.
