American CuMo Mining Corp. Files Technical Report
Vancouver, May 30, 2018 - American CuMo Mining Corp. (TSXV: MLY) (OTC Pink: MLYCF) ("CuMoCo" or the "Company") announces it has filed a 43-101 technical report on an independent updated Preliminary Economic Analysis (PEA) of the Company's 100% owned Copper-Molybdenum-Silver deposit located in Boise County, Idaho. The report focuses on demonstrating the positive economic effects that Mineral Sorting has on the CuMo Project and provides an updated economic analysis at current and a variety of other metal prices. The purpose of revising the PEA was to update the economic section of the 2015 summary report released November 2015 by adding the Mineral Sorting benefits to the project. The PEA is a prelude to a Pre-Feasibility Study and allows the Company to independently verify the benefits of Mineral Sorting to the CuMo Project in a relatively short period. The 150,0000 tons per day case was selected for updating.
For readers to fully understand the information in this news release, they are encouraged to read the complete PEA technical report, which the Company has filed on SEDAR (www.sedar.com), in accordance with NI 43-101. The report is also available on the Company's website, including all qualifications, assumptions, and exclusions that relate to the PEA. The technical report is intended to be read in its entirety and sections should not be read or relied upon out of context.
Initially, to make a direct comparison between the two economic report sections and to show the benefits of Mineral Sorting, the price of molybdenum and copper used in the comparison were kept the same as the original 2015 report.
| Metal | Price per unit |
| Mo (lbs) | US$15 |
| MoO3 (lbs) | US$10 |
| Cu | US$3 |
| Silver (oz) | US$17.5 |
| Rhenium (kg) | US$2000 |
| Sulfuric acid (ton) | US$75 |
Highlights of the comparison are:
- An increase in pre-tax net cash flow from $30.0 billion to $32.8 billion
- An increase in pre-tax net present value at a 5% discount (NPV5) from $9.0 billion to $10.7 billion
- An increase in after-tax net cash flow from $20.79 billion to $22.98 billion
- An increase in after-tax net present value at a 5% discount (NPV5) from $7.2 billion to $7.7 billion
- An increase in production of molybdenum, copper, and silver
- An overall decrease in cost to produce a pound of molybdenum oxide (MoO3) (net of byproducts) from $3.91 to $1.58 per pound or an overall decrease in cost to produce a pound of molybdenum metal (Mo) (net of products) from $5.87 to $2.37 per pound.
In the updated results, the Company and Sacré-Davey Engineering decided to produce the current economics using the following metal prices:
| Metal | Price per unit |
| Mo (lbs.) | US$12.5 |
| MoO3 (lbs.) | US$8.33 |
| Cu | US$3 |
| Silver (oz) | US$17.5 |
| Rhenium (kg) | US$2000 |
| Sulfuric acid (ton) | US$75 |
The price of molybdenum(Mo) is reduced to $12.50 due to a price reduction in long-term average prices of molybdenum. According to Roskill and Platts, molybdenum(Mo) is currently trading in the $12.80 to $12.90 per pound range.
The following table shows the current highlights from the updated results:

Cautionary statement NI 43-101: The PEA was prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). Readers are cautioned that the PEA is preliminary in nature. 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 PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
The report also analyzed the effects on the Internal Rate of Return (IRR) and the Net Present Values (NPV) of varying metal prices on the economics using the following metal prices:
| Cu Price | Mo Price | Ag Price | Rh Price | Sulphuric Acid Price |
| $US/lb | $US/lb | $US/troy oz. | $US/kg | $US/t (short ton) |
| $2.00 | $9.00 | $10.50 | $1,200.00 | $50.00 |
| $2.60 | $12.00 | $14.00 | $1,500.00 | $60.00 |
| $3.00 | $15.00 | $17.50 | $2,000.00 | $75.00 |
| $3.50 | $18.00 | $21.00 | $2,500.00 | $90.00 |
| $4.00 | $21.00 | $24.50 | $2,800.00 | $100.00 |
In addition, the operating and capital costs were varied from the base costs by -40, -20, -10, 10, 20%, 40%.
This analysis was conducted by varying one parameter at a time to determine an IRR and NPV. The results of this analysis are depicted below:
| Scenario | Pre-Tax Sensitivity | |
| IRR | NPV (5%) | |
| Low | 15.8% | $3,970.0 |
| Current Base Case | 28.7% | $7,910.8 |
| High | 44.6% | $17,480.0 |
| Scenario | After-Tax Sensitivity | |
| IRR | NPV (5%) | |
| Low | 13.7% | $2,770 |
| Current Base Case | 25.0% | $5,673.0 |
| High | 37.1% | $12,680.0 |
"We are extremely pleased with the updated Preliminary Economic Assessment. The CuMo Project is the largest Molybdenum, Silver, Rhenium and Tungsten deposit in the United States and one of the world's premier mines in terms of size, cost, and economics," said Shaun Dykes, President and Chief Executive Officer of CuMoCo. "The project design incorporates features which will provide the highest levels of environmental protection, workforce safety, and operating efficiency while minimizing community impacts. We intend to continue advancing the CuMo Project responsibly for the benefit of all stakeholders — governments, employees, communities, and shareholders. We are now focused on completing the remaining permitting, pre-feasibility, and feasibility efforts."
The Company and Sacré-Davey Engineering personnel have identified several areas and opportunities that may provide significant costs savings and improved economics for the project, including the following:
Mining
- Optimization of the production schedule, including examining an increase in cutoff grade which would have the effect of reducing the current 82-year mine life but increasing the amount of metal being produced and thus the profitability and reducing the cost to produce.
- Optimization of the pit designs and definition of a mineable reserve.
- Optimization of waste and stockpile haulage methodology by switching to conveyor-based systems to reduce the amount of trucking involved and thus costs.
- Detailed equipment costing to determine potential discounts to list price for all major components.
Milling
- Additional metallurgical work to determine optimum grind size (the current assessment is based on the finest grind tested to date), analyze recoveries of the various metals, and analyze the effects of the higher grade coming from the mineral sorters on metal recoveries.
- Optimize reagents to reduce costs and improve metallurgy.
- Work on the potential for a tungsten recovery circuit is required (currently excluded).
Tailings
- Detailed analysis of tailings storage facilities and design to reduce overall costs.
Other
- Examine alternative concentrate transportation from the mill to the railhead.
- Optimization of the roaster capital and operating costs.
"These optimizations and further studies will be examined in more detail as part of the Pre-Feasibility Study the Company will commence later this year, with the goal of continuing to further reduce overall capital and operating costs and improve the already exceptional economics of our CuMo Project," stated Mr. Dykes.
