American CuMo Mining

Advancing the World’s Largest and Lowest-cost Molybdenum-Copper-Silver Mine

This American CuMo Mining Corporation profile is part of a paid investor education campaign.*


American CuMo Mining Corporation (TSXV: MLY) is a Canadian-based mining company with two polymetallic properties with critical mineral components in resource-rich Idaho. American CuMo is currently advancing its two U.S.A. projects—the world-class CuMo Project and Calida Gold. Each project is managed by industry experts at Idaho CuMo Mining Corporation, the wholly-owned subsidiary of American CuMo.

The Company is establishing itself as a low-cost, top-tier molybdenum producer through the advancement of its CuMo Project, ranked among the top five most profitable mines. The project located near Boise, Idaho is potentially the world’s largest and lowest-cost primary molybdenum mine. The property also hosts the third largest copper deposit and the largest silver deposit in the U.S. Critical minerals, tungsten and rhenium, which have been deemed necessary to the U.S. economy and national defense by the United States Geological Survey, are present in the CuMo deposit. CuMo is projected to become the largest source tungsten and rhenium in the U.S.

An updated PEA released in April 2018 showed an after-tax NPV (5 percent) of US$5.7 billion, and IRR of 25 percent and an average cash flow of US$664 million over the first five years.

The global market for molybdenum is experiencing strong fundamentals. Demand for the metal is expected to grow at a CAGR of 4.6 percent between 2018 and 2025 on robust demand for steel from substantial infrastructure initiatives across the globe. At the same time, supply is constrained by aging existing production and changes in the financials, infrastructure and geopolitical implications of planned projects.

American CuMo’s Calida Gold, located in eastern Idaho’s historic mining region, hosts significant gold, silver and copper mineralization. The property has been extensively explored for the past thirty years. Exploration has included drilling 29 holes in 1983 as well as thorough trenching and sampling.

American CuMo Mining is led by a senior management team of mine development professionals and a technical team with more than 260 years of feasibility-level experience including metallurgy, mill and mine design, as well as environmental sustainability and permitting.

Key Assets

CuMo Project – World’s Largest Un-Mined Molybdenum Deposit With Critical Mineral Components

American CuMo’s wholly-owned CuMo Project is located 35 miles northeast of Boise, Idaho at the southwestern end of the Idaho-Montana Porphyry Belt. The property consists of 184 contiguous mining lode claims covering an area of approximately 3,720 acres and 38 patented claims covering a total area of 740 acres, located in the historic Boise Basin mining district – an area in which gold was discovered in 1862 and exploration and mining has been taking place continuously since that time.  The CuMo deposit is classified as a porphyry molybdenum-copper deposit. The vast size of the CuMo deposit has had analysts place it among the top five most profitable mines and gives the project an economic scale equivalent to or exceeding that of high-grade molybdenum deposits such as Henderson or Climax.


The region hosts excellent infrastructure including major road and rail network access, electric power and water. Exploration and mining can be conducted year-round, due to its proximity to an established road network. The area is serviced by the Idaho Power Company and the nearest rail line is the Idaho Northern & Pacific line that runs through the town of Horseshoe Bend, near CuMo’s warehouse and its center for field operations. Equipment, supplies and services for exploration and mining development projects are available at Boise as well as a trained mining-industrial workforce.


CuMo Resource Estimate

Based on the data compiled from the 2005 – 2012 drill campaigns, a Measured, Indicated and Inferred resource estimate for the project was determined in the November 2015 independent NI 43-101 Technical Report (see table below).


Preliminary Economics: Potentially the world’s largest, lowest-cost moly mine

Could, potentially, stand among the top 5 most profitable mines.

The diversity of metals found at CuMo occurs in two distinct layers: the upper half of the CuMo deposit contains higher grades of silver and copper compared to molybdenum while the lower half is rich in molybdenum, with lower grades of silver and copper. The total recoverable value of both layers is what gives the CuMo Project such excellent economic potential. The copper value alone is expected to contribute from 25 percent to 30 percent of revenues, helping to reduce overall operations costs.

With intensified focus on U.S. critical minerals exploration and development, CuMo is qualified to be prioritized by the U.S. government as a sustainable source for rhenium and tungsten. Throughout 2017-18, U.S. executive orders and legislative actions have renewed national commitment to streamlining permitting and approval processes for strategic mineral development and production in the U.S. CuMo is positioned to benefit from these initiatives.

Note that the preliminary economic  analysis is preliminary in nature, that it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary assessment will be realized.

Ore-Sorting: Optimizing profitability through technology

American CuMo announced in January 2017 that the use of Ore-Sorting technology at the CuMo deposit has the potential to increase the value of direct processing feed by up to 270 percent. Ore-Sorting uses state-of-the-art x-ray technology to identify and separate rocks that contain processing grade minerals from those that do not.


Ore-Sorting technology may allow the CuMo Project to be mined at large tonnages (200K to 300K tpd) while requiring only smaller tonnages (50K to 100K tpd) to recover most of the metals—resulting in a significant increase to profitability and reductions in capital and operating costs. The Company estimates this could lead to a CAPEX savings of between US$800 million and US$1 billion.

“The updated resource calculation and our most recent Preliminary Economic Assessment combined with these excellent Ore-Sorting results confirm again that CuMo is able to compete on a cost-to-produce basis with not only primary molybdenum producers, but also with copper projects producing molybdenum as a by-product,” said American CuMo President and CEO Shaun Dykes.


Ore-Sorting is the first of several optimizations in preparation for Pre-Feasibility and Feasibility Studies on the CuMo deposit. American CuMo is finalizing the incorporation these results into the updated 2018 PEA. A series of large bulk samples are planned for feasibility accuracy level metallurgical testing. The results of both the ore-sorting and metallurgical test work will then be used to complete a feasibility-level economic study.

Multi-Phase Mine Development Plan

American CuMo plans to begin feasibility-stage drilling in Q3 2018.

Environmental Permitting at Mid-Level Stage

The CuMo Project sits in the historically mined Grimes Creek Basin.  The project area lacks any endangered species or plant life and is not located in a wilderness or pristine area, but a heavily disturbed and mildly contaminated area of historic mining and logging. Logging and mining activity over the past 100 years has contaminated the creek, according to the Idaho State Department of Environmental Quality.

North American project development is governed by three levels of increasingly stringent analyses to evaluate the environmental impacts of proposed projects. The CuMo Project and exploration team completed the Lower Level Categorical Exclusion (CE) in 2011 and have received the necessary Middle Level Environmental Assessment (EA) permits twice and are in the process of having them renewed a third time,  to proceed with advanced exploration and site analysis. American CuMo continues to gather the required scientific information to bring the project to the highest level Environmental Impact Statement (EIS).


Calida Gold: Substantial Gold, Copper and Silver Deposit

American CuMo’s subsidiary, Poly Resources LLC, is the financial and management vehicle for developing large-scale mining projects and holds a 100-percent interest in Calida Gold. The 1,050-acre property is located approximately 24 miles south of Salmon, Idaho and consists of several historically producing mines. This production occurred along several separate shear zones with significant output of gold, silver and copper.


Extensive past exploration at Calida includes trenching, sampling as well as 29 drill holes completed in 1983. Highlights from those results are shown in the table below.


In 2009, this historical data was used to complete an independent (non NI-43 101 compliant) resource calculation for Calida Gold which included 8,059,304 tons grading 0.168 oz/t gold, 6.12 oz/t silver and 2.86 percent copper. (Note: As this is an historical resource estimate, readers are cautioned that a Qualified Person has not done sufficient work to classify the historical estimate as current mineral resources. The issuer is not treating the historical estimate as current mineral resources but as a guide, and the historical estimate should not be relied upon.)

Ten mineralized veins hosting oxide and sulfide ore minerals have been identified to date, ranging in size from 1.5 meters to 30 meters in width and up to 4,267 meters in length.  American CuMo has examined the data and determined a target area measuring 80 to 120meters wide, 1,400 to 1,600 meters long and 400 to 600 meters deep that contains gold with copper-bearing mineralization.
