Nevada Copper Files Integrated Feasibility Study on Sedar

July 9, 2015

July 9, 2015 - Nevada Copper Corp. (TSX: NCU) (“Nevada Copper”) (the “Company”) is pleased to announce that it has completed, and SEDAR-filed, a National Instrument 43-101 (“NI 43-101”) Integrated Feasibility Study Technical Report for its 100%-owned Pumpkin Hollow Copper Project located near Yerington, Nevada.

The Integrated Feasibility Study describes the proposed development of a 70,000 tons per day copper concentrator with mill feed from both open pit and underground mine operations. The Technical Report, entitled “NI 43-101 Technical Report Integrated Feasibility Study, Pumpkin Hollow Project Yerington, Nevada” (“IFS”), has an effective date of April 15, 2015. This technical report supersedes all previous technical reports on the Pumpkin Hollow Copper Project.

The IFS was prepared under the direction of Tetra Tech, Inc. (“Tetra Tech”) with Stantec Consulting Services Inc. (“Stantec”) having responsibility for the detailed underground mine design and underground capital cost estimation. Tetra Tech and Stantec are both industry-leading international engineering firms.

Highlights of the Integrated Feasibility Study (All dollar amounts are stated in United States currency)

Reserves and mine production are as reported in the May 28, 2015 press release however, certain costs differ slightly from previously reported amounts:

  • Long mine life of 23 years with low-risk profile located in an ideal mining jurisdiction close to existing infrastructure, an increase of 5 years from the first published integrated feasibility study, with production ramp-up targeted for 2018;
  • Assuming the Base Case of US$3.15 copper, US$1,200 gold and US$18 silver, the Integrated Project generates Life-of-Mine (“LOM”) after-tax net cash flow of US$2.5 billion, NPV@ 5% of US$1.1 billion, an after-tax IRR of 15.6% with 4.7 year payback;
  • Significant LOM metal production of 4.5 billion pounds (2.05 million tonnes) of copper, 512,000 ounces of gold and 15.6 million ounces of silver in a quality copper concentrate. Average annual copper production of 275 million pounds in years 1 to 5;
  • The project development contemplates a 63,500 tons/day open pit mine and 6,500 tons/day underground mine, feeding a single 70,000 tons/day concentrator, generating substantial annual cash flow over LOM;
  • Proven and Probable Mineral Reserves, including open pit and underground mineable, are 572 million tons of ore grading 0.47% copper equivalent1, containing 5.05 billion pounds of copper, 761,000 ounces of gold and 27.6 million ounces of silver;
  • Initial capital costs are estimated to be $1.04 billion including contingencies, excluding working capital of $33 million. Sustaining LOM capital is $0.63 billion;
  • Low LOM site operating costs of $11.80 per ton of ore-milled (Year 1 to 5 - C1 Production Costs at $1.49/lb. payable copper), excluding leased equipment and Nevada State Minerals Tax;
  • The IFS includes drilling data to 2011 for the underground deposits and 2013 for the open pit deposits. Further upside and optimization potential exists from current drilling in 2015 which is not included in the IFS; and
  • The IFS confirms the technical and financial viability of constructing and operating a 70,000 tons/day copper mining and processing operation at Pumpkin Hollow comprising a single large concentrator with mill feed from both open pit and underground operation.

1The copper grade equivalency was determined using Base Case metals prices and metallurgical recoveries of 89.3%, 67.3% and 56.3% for copper, gold and silver respectively

Annual copper production in concentrates and C1 operating costs:

Capital Costs

The project initial capital costs are estimated at $1.04 billion with an accuracy of plus/minus 15% as of March 2015, including an initial contingency of $67 million. The contingency allowance is calculated based on assessed factors for each of the major Direct and Indirect cost categories.

The major direct cost items include development of the East underground mine, open pit mine equipment, leasing costs, North deposit pre-stripping, process plant, tailing storage facility, site infrastructure and offsite rail load-out facility. Indirect costs include such major areas as engineering and procurement, construction management, construction indirects, freight and commissioning, spares inventory, first fills, and Owners Costs.

Total Capital$1,041$634$1,675

Note: totals may not add due to rounding

Working capital required for initial operations is estimated to be $33 million.

LOM sustaining capital totals $0.63 billion and includes development costs associated with the E2 underground deposit and related equipment; South open pit deposit development costs; replacement of, and additions to, surface mobile equipment; expenditures on the tailings storage facility, and reclamation costs, net of salvage value at the conclusion of the project.

Operating Costs

LOM site unit operating cash costs, net of capitalized pre-stripping and other predevelopment costs, are $11.80 per ton-milled, as summarized in the table below:

LOM Unit Operating Cost Summary
Open Pit Mining$5.03
Underground Mining1.45
Tailings & Water Management0.17
Total LOM Site Operating Costs$11.80

Note: The cost of operating leases and Nevada Net Proceeds of Mining tax adds $0.72/ton and $0.28/ton, respectively.

Unit open pit mining cash costs average $5.34 per ton of open pit ore mined and milled. This equates to $1.16 per ton of open pit material mined, including waste and ore. Average LOM strip ratio for the North and South deposits is 3.59. Underground mining costs average $24.06 per ton of underground ore mined, excluding $1.25 for truck transport of ore to concentrator.

Alternative Performance Measures

“Copper Production Costs”, “LOM Operating Costs”, “LOM site unit operating costs”, “C1 Production Costs” and similar terms are +alternative performance measures. These performance measures are included because these statistics are key performance measures that management may use to monitor performance. Management may use these statistics in future to assess how the Company is performing to plan and to assess the overall effectiveness and efficiency of mining operations. These performance measures do not have a meaning within International Financial Reporting Standards (“IFRS”) and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with IFRS.
