February 11, 2013 - Vancouver, British Columbia - NovaCopper Inc. (TSX, NYSE-MKT: NCQ) ("NovaCopper" or "the Company") has filed a National Instrument 43-101 ("NI 43-101") technical report (the "Report") on the combined South Reef and Ruby Creek zones of the Bornite Project located in the highly prospective Ambler Mining District of northwestern Alaska. As previously announced by the Company on February 5, 2013, the Report estimates additional Inferred Resources of 2.4 billion pounds of copper consisting of 43.1 million tonnes at an average grade of 2.54% copper at the South Reef zone. The report was compiled by Mr. Bruce Davis, FAusIMM, the president of BDRC and Mr. Robert Sim P.Geo. of Sim Geological Inc. The Report has been filed on SEDAR and EDGAR and is also available on the Company's website at www.novacopper.com.
Highlights
- At the base case 1.0% copper cutoff grade, the South Reef zone is estimated to contain an Inferred Resource of 43.1 million tonnes at 2.54% copper or 2.4 billion lbs of contained copper (see Table 1 for details).
- At an elevated 2.0% copper cutoff grade, the South Reef zone is estimated to contain an Inferred Resource of 25.0 million tonnes at 3.44% copper or 1.9 billion lbs of contained copper (see Table 1 for details).
- The Bornite Project (combined South Reef and Ruby Creek zones) is now estimated to contain 179 million lbs of copper (6.8 million tonnes grading 1.19% copper) in the Indicated category and 3.3 billion lbs of copper (90.8 million tonnes grading 1.64% copper) in the Inferred category (see Table 3 for details).

Table 4. Estimated Mineral Resources - Arctic Project(5)(6)(7)(8)(9)
- Base Case is 1.0% Cu cut-off grade.
- Mineral resources at a 1.0% cutoff are considered as potentially economically viable in an underground mining scenario based on an assumed projected copper price of US$2.75 per lb and total site operating costs of US$60 per tonne.
- Base Case is 0.5% Cu cut-off grade.
- Resources stated as contained within a potentially economic resource manually constructed limiting pit shell using metal price of US$3.00 per lb Cu, mining costs of US$1.50 per tonne, processing costs of US$10.00 per tonne, 100% recoveries and an average pit slope of 45 degrees.
- Resources stated as contained within a potentially economically minable underground shapes above a US$75.00/t NSR cut-off.
- NSR calculation is based on assumed metal prices of US$2.50/lb for copper, US$1,000/oz for gold, US$16.00/oz for silver, US$1.00/lb for zinc and US$1.00/lb for lead. A mining cost of US$45.00/t and combined processing and G&A costs of US$31.00 were assumed to form the basis for the resource NSR cut-off determination. Note these metal prices and operating costs may differ from those used for the cash flow model.
- Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources will be converted into Mineral Reserves.
- Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding.
- The above table refers to "inferred resources". We advise United States investors that this term is not recognized by the SEC. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources. United States investors are cautioned not to assume that estimates of inferred mineral resources exist, are economically minable, or will be upgraded into measured or indicated mineral resources.

All statements, other than statements of historical fact, included herein, without limitation, statements relating to the future operating or financial performance of NovaCopper, are forward-looking statements. Forward-looking statements are frequently, but not always, identified by words such as "expects", "anticipates", "believes", "intends", "estimates", "potential", "possible", and similar expressions, or statements that events, conditions, or results "will", "may", "could", or "should" occur or be achieved. These forward-looking statements may include statements regarding perceived merit of properties; exploration results and budgets; mineral reserves and resource estimates; work programs; capital expenditures; timelines; strategic plans; completion of transactions; market prices for precious and base metals; or other statements that are not statements of fact. Forward-looking statements involve various risks and uncertainties. There can be no assurance that such statements will prove to be accurate, and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause actual results to differ materially from NovaCopper's expectations include the uncertainties involving the need for additional financing to explore and develop properties and availability of financing in the debt and capital markets; uncertainties involved in the interpretation of drilling results and geological tests and the estimation of reserves and resources; the need for cooperation of government agencies and native groups in the development and operation of properties; the need to obtain permits and governmental approvals; risks of construction and mining projects such as accidents, equipment breakdowns, bad weather, non-compliance with environmental and permit requirements, unanticipated variation in geological structures, ore grades or recovery rates; unexpected cost increases, which could include significant increases in estimated capital and operating costs; fluctuations in metal prices and currency exchange rates; and other risk and uncertainties disclosed in NovaGold Resources Inc.'s Management Information Circular dated February 27, 2012 for the special meeting of securityholders held to consider the spin-out of NovaCopper Inc. filed with the Canadian securities regulatory authorities, and NovaCopper's registration statement on Form 40-F filed with the United States Securities and Exchange Commission and in other NovaCopper reports and documents filed with applicable securities regulatory authorities from time to time.

Cautionary Note to United States Investors
This press release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all resource and reserve estimates included in this press release have been prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards on Mineral Resources and Mineral Reserves. NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the United States Securities and Exchange Commission ("SEC"), and resource and reserve information contained herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, the term "resource" does not equate to the term "reserves". Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. The SEC's disclosure standards normally do not permit the inclusion of information concerning "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" or other descriptions of the amount of mineralization in mineral deposits that do not constitute "reserves" by U.S. standards in documents filed with the SEC. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. U.S. investors should also understand that "inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an "inferred mineral resource" will ever be upgraded to a higher category. Under Canadian rules, estimated "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies except in rare cases. Investors are cautioned not to assume that all or any part of an "inferred mineral resource" exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in-place tonnage and grade without reference to unit measures. The requirements of NI 43-101 for identification of "reserves" are also not the same as those of the SEC, and reserves reported by the Company in compliance with NI 43-101 may not qualify as "reserves" under SEC standards. Accordingly, information concerning mineral deposits set forth herein may not be comparable with information made public by companies that report in accordance with U.S. standards.
1 The Ambler copper-equivalent resource is calculated using the following metals price assumptions: (in USD) $3.93/lb Cu, $1,815/oz Au, $40.55/oz Ag, $0.98/lb Zn, and $1.08/lb Pb; and is based on grades of 4.05% Cu, 0.80 g/t Au, 59.55 g/t Ag, 5.81% Zn, and 0.97% Pb.
