First Vanadium Announces Positive Preliminary Economic Assessment for the Carlin Vanadium Project in Nevada

 

 

 

 

 

First Vanadium Corp. (TSX-V: FVAN) (OTCQX: FVANF) (FSE: 1PY) announces positive results on its Preliminary Economic Assessment for the Company’s Carlin Vanadium Project located 6 miles south from the town of Carlin, Nevada in the United States. The PEA has been prepared by independent consultant Wood Canada Limited (Wood) in accordance with National Instrument 43-101. The PEA is based on the Mineral Resource Estimate outlined in the Company’s Technical Report dated April 9, 2019. The PEA demonstrates positive economics for a large-scale open pit mining operation, with 16 years of Vanadium production and 4 additional years of acid/power sales.

 

Paul Cowley, President and Chief Executive Officer, said, “The PEA crystalizes potential economics for the Company’s vanadium asset and provides for design options and enhancement opportunities. Unit Operating costs averaging US$4.81/lb V2O5 in the first 10 years and US$5.17/lb V2O5 over Life of Mine are of significant note, and in the range of lower quartile operating costs of vanadium producers. We can see numerous opportunities to lower both Capex and Opex to benefit the vanadium asset which we will act upon to advance the project.”

 

“With a positive PEA, the Carlin Vanadium Project becomes an even more important resource of a critical and strategic metal essential to protecting US national interests, particularly as the US looks towards vital future domestic sources of strategic metals which includes vanadium.”

 

Paul Cowley continues, “In addition, the benefit of having both vanadium and a separate gold opportunity on the same property located within the world-famous Carlin Gold Trend is unique, broadens our opportunities and is another of our many strengths. With our goal to maximize on all our high-quality opportunities to enhance value for our shareholders, it is now time to bring our exceptional gold opportunity to the forefront with the aim to drill-test this summer. This drill program will be led by Ex-Newmont Regional Manager and proven mine-finder, Dave Mathewson who has found 6 gold deposits within 3-9 miles of the property.”

 

PEA Highlights (US$ unless otherwise noted):

 

  • Life of mine (LOM) of 11 years of mining plus 5 years of stockpile feed, with 1.0 million tons annually of process plant feed at an average grade of 0.71% V2O5 and average process recovery rates of 78%, resulting in an annual average payable production of 11 million pounds of V2O5 flake
  • Project includes a 4 year extension post-mineral processing of stockpiles, selling sulfuric acid and energy exclusively from acid plant
  • Total payable production: 180 million pounds of V2O5 flake
  • LOM average cash operating cost per payable V2O5 pound: US$5.17/lb V2O5; US$4.81/lb V2O5 over the first 10 years
  • Pre-Production capital requirements: US$535 million
  • Undiscounted cash flow Pre-tax: US$356 million, Undiscounted cash flow After-tax: US$301 million
  • Pre-tax NPV (6%): US$56 million, After-tax NPV (6%): US$29 million
  • Pre-tax IRR: 7.9%, After-tax IRR: 7.0%
  • Pre-tax Payback period: 7.5 years, After-tax Payback period: 7.7 years
  • Assumed metal price of US$10.65/lb V2O5
  • Potential for up to 230 jobs at the peak of production

 

The preliminary economic assessment is preliminary in nature, and 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 economic assessment will be realized. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

Project Summary

 

The Carlin Vanadium Project is located 6 miles south of the town of Carlin, Nevada, and within the Carlin Gold Trend, Nevada’s most prolific gold mining trend, dominated by Barrick and Newmont. The project possesses strong infrastructure being only 6 miles by road to a major highway, rail hub, power and skilled mining work force. The project is a near surface primary vanadium resource hosted in black shale, the largest highest-grade resource of its kind in North America.

 

Mining

 

The mine design is based on two objectives; firstly, to mine the highest grade in the oxides, followed by non-oxides, and secondly, once the whole deposit is mined, tailings produced by feeding the stockpiles would be stored in the pit. A drill, blast, load, and haul profile has been built into the model at an average cost of US$$2.30/ton, however, it may be possible that some of this material can be mined without drilling or blasting. This will be determined in subsequent studies. A total of 69 million tons of material will be mined over the 11-year life of the open pit, mined in phases. Maximum material moved in any one year will be 7 million tons. Nine million tons of oxide and seven million tons of non-oxide material with an average strip ratio of 3.22:1 will be moved over the life of the pit. The overall grade of the mined resource will be 0.71% V2O5 and will include a 6 million ton lower grade stockpile that will be processed when the pit is complete in years 12 to 16.

 

Metallurgy and Processing

 

The process plant is designed to produce V2O5 as a saleable product from two distinct material types that make-up the resource, oxide and non-oxide shales, using conventional equipment and conventional beneficiation and hydrometallurgical techniques. The Run-Of-Mine (ROM) oxide feed from the mine is attrition scrubbed and classified to produce an oxide concentrate. The Run-Of-Mine (ROM) non-oxide feed from the mine is crushed, ground, attrition scrubbed/classified and floated to produce a non-oxide concentrate. Both concentrates follow steps of acidulation, pressure oxidation, impurity removal, vanadium solvent extraction and precipitation as ammonium metavanadate (AMV). Finally, AMV is calcined to form V2O5 product. The overall recovery of V2O5 through the process flowsheet for oxide material is estimated at 78.6%. The overall recovery of V2O5 for non-oxide material is estimated at 77.4%.

 

Project Economics and Sensitivities

 

The economic results of the PEA are summarized in Table 2 on an after-tax basis. The sensitivities and the impact of cash flows have been calculated up to +/- 45% variations against the base case. Project economics include a 4 year post mineral processing extension, when only the acid plant is operating and producing sulfuric acid and energy for sale, which generate a contribution to the after-tax project economics of US$40 million to the cashflow and US$12 million to the NPV@6%.

Further Project Enhancement Opportunities

 

The Company believes that there are numerous opportunities to enhance the Carlin Vanadium Project further through:

 

  • Expanding and defining, by drilling, additional oxide mineralization to the northwest end of the deposit, and additional non-oxide mineralization to the east and west of the deposit, all to the Indicated category thereby extending the processing period of high-grade resources beyond year 12 and deferring the processing of lower grade stockpiles;
  • More detailed process test work, engineering and project definition may reduce capital costs or contingencies;
  • Further testing of higher efficiency centrifuge separation that could reduce mass pull in pre-concentration stage and thereby reduce operating costs and improve recoveries;
  • Further testing of alternative technologies in solid-liquid separation to potentially reduce the size of the tailing facility, and IX and SX plants and thereby potentially reducing capital costs; and;
  • The PEA will make recommendations to enhance and advance the vanadium project, as a phased work approach to completing a Pre-Feasibility study, which would update the Project study to a higher level of precision.

 

Mineral Resource

 

The pit constrained Mineral Resource Estimate which formed the basis of the PEA, is set out in Table 3.

 

Table 3: Pit Constrained Mineral Resource Estimate for Carlin Vanadium Project- Effective January 31, 2019.

 

 

Classification Cut-off (% V2O5) Grade (% V2O5) Tons (M) V2O5 lb (M)
Indicated 0.3 0.615 24.64 303
Inferred 0.3 0.520 7.19 75

 

  • Mineral Resources are not Mineral Reserves. Mineral resources which are not mineral reserves do not have demonstrated economic viability. There has been insufficient exploration to define the Inferred Resources tabulated above as an Indicated or Measured Mineral Resource. There is no guarantee that any part of the mineral resources discussed herein will be converted into a mineral reserve in the future.
  • The Mineral Resources in this estimate were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Definition Standards for Mineral Resources and Mineral Reserves (May 10, 2014), and Best Practice Guidelines adopted by CIM Council.
  • The mineral resources listed in Table 14-4 are confined within a Whittle Pit Shell with a 45⁰ pit slope and a strip ratio of 2.6:1 including all categories. The following parameters were used to construct the Whittle pit shell and to derive the mineral resource cut-off grade of 0.3% V2O5: Metal prices: US$12.50/lb V2O5 flake, Mining: US$2.50/t, Processing: US$52.50/t, G&A: US$1.50/t, Product Transport: $2.00/t, Process Recovery: 85%.
  • Contained pounds may not add due to rounding.
