RC13-224 intersects two high-grade mineralized intervals comprising 229.4 meters grading 1.73% Cu and 6.6 meters grading 7.70% Cu

Drilling demonstrates the possibility of two major mineralized zones connecting at depth with resultant expansion of the underground target

TSX, NYSE-MKT Symbol: NCQ

VANCOUVER, Oct. 7, 2013 /PRNewswire/ - NovaCopper Inc. (TSX: NCQ) (NYSE: NCQ) ("NovaCopper" or "the Company") is pleased to announce initial assay results from exploration diamond drilling at its Bornite Project, which is part of the Upper Kobuk Mineral Projects ("UKMP") located in the Ambler mining district of Northwest Alaska. This is the first set of drilling results, comprising two holes out of 17, which total approximately 8,140 meters drilled in 2013 at Bornite.  Additional drill results are anticipated to be released regularly over the next several weeks as they become available.  The 2013 drilling campaign was designed to expand mineralization in two discrete settings: 1) near-surface, moderate-grade (~1% copper) and potentially open-pit amenable mineralization at the Ruby Creek zone; and 2) deeper, high-grade and potentially underground exploitable mineralization of both the South Reef and Ruby Creek zones.   This initial press release reports on the first two deep offset holes to the north on both the South Reef and Ruby Creek zones. Most significantly these two deep holes appear to link the two zones, therefore, greatly increasing the scale of the expanding underground target.

Highlights

Both holes intersected significant intervals of high-grade copper mineralization:

At a cutoff grade of 0.5% copper the results are as follows:

  • RC13-220 intersected two mineralized intervals, starting at 809.1 meters and ending at 940.4 meters (131.3 meter interval), for a combined  126.0 meter composite interval with a weighted average grade of 1.59% copper and comprised of:
    • 45.6 meters at a grade of 1.07% copper; and
    • 80.4 meters at a grade of 1.89% copper.
  • RC13-224 intersected two mineralized intervals, starting at 513.3 meters and ending at 754.6 meters (241.3 meter interval), for a combined  236.0 meter composite interval with a weighted average grade of 1.90% copper and comprised of:
    • 229.4 meters at a grade of 1.73% copper; and
    • 6.6 meters at a grade of 7.70% copper.

At a cutoff grade of 2.0% copper the results are as follows:

  • RC13-220 intersected three mineralized intervals, starting at 877.1 meters and ending at 923.3 meters (46.2 meter interval), for a combined  35.5 meter composite interval with a weighted average grade of 3.04% copper and comprised of:
    • 5.9 meters at a grade of 6.66% copper;
    • 9.9 meters at a grade of 2.48% copper; and
    • 19.7 meters at a grade of 2.24% copper.
  • RC13-224 intersected five mineralized intervals, starting at 578.7 meters and ending at 754.6 meters (175.9 meter interval), for a combined 90.9 meter composite interval with a weighted average grade of 2.98% copper and comprised of:
    • 19.5 meters at a grade of 3.02% copper;
    • 16.8 meters at a grade of 2.36% copper;
    • 39.5 meters at a grade of 2.37% copper;
    • 8.6 meters at a grade of 3.26% copper; and
    • 6.5 meters at a grade of 7.70% copper.

Drill hole RC13-224 constitutes the thickest mineralized intercept yet drilled at Bornite and is the second best drill hole so far drilled at the UKMP in terms of contained metal. Three additional drill holes, RC13-227, RC13-231 and RC13-233, were subsequently drilled to further define the potential link between the two deep mineralized zones.  Complete assay results for these holes will be reported in the next release of results.

"The 2013 exploration campaign at Bornite continues to produce impressive high-grade drill results. We are encouraged by the fact that the deeper high-grade copper mineralization at the Ruby Creek zone appear to be linked with similar high-grade mineralization at the South Reef zone, potentially yielding a continuous, thick zone of mineralization approximately one kilometer down dip and over one kilometer along strike.  This new finding from the 2013 drilling campaign could greatly expand the mineral resources at Bornite, which are potentially exploitable by underground mining methods. This year's program, which included core re-logging and re-assaying on 32 historically drilled holes, is also expected to result in the expansion of the near-surface, potentially open-pittable mineralization at Bornite.  We believe that these drilling results together with our previous drilling results could result in a material increase in the estimated mineral resources at Bornite," said Rick Van Nieuwenhuyse, NovaCopper's President and Chief Executive Officer.

Results are presented in Table 1 at a cutoff grade of 0.5% copper so as to be comparable with previous drill results released by NovaCopper Inc. in 2011 and 2012.

Exploration in 2013 at Bornite was designed to further define and advance both the shallow moderate-grade open-pit potential and the high-grade underground resources. The open-pit target covers the shallow surface projection of the historically drilled Lower Reef and the smaller but higher grade mineralized area, the Upper Reef, which is located stratigraphically higher in the carbonate stratigraphy. These two areas of mineralization define a NNE-trending zone called the Ruby Creek zone which management believes may have the potential to be an open-pit mining operation. Grades in this zone are on the order of 0.8% to 1.2% copper as reported in the NI 43-101 Technical Report on the Ruby Creek zone which was filed on SEDAR and EDGAR on July 18, 2012.

Down-dip and lateral exploration on the Lower Reef in 2011 and 2012 led to the discovery of the South Reef zone, a parallel NNE-trending zone of high-grade mineralization as reportedin theNI 43-101 Technical Report which was filed on SEDAR and EDGAR on February 11, 2013. This year's drilling has now linked the two NNE-tending mineralized zones in the Lower Reef at depth into one continuous mineralized zone. The four most northerly holes exploring the Lower Reef (the first two of which are reported herein) suggest a high-grade continuous zone of stratiform copper mineralization over a kilometer in width with thicknesses exceeding 100 meters. Figure 1 shows the spatial relationships between the open-pit and underground resource areas as well as the collar locations of historic and 2013 drilling.

Figure 2 shows a NNE- trending section down the axis of the South Reef zone showing 2012 drilling and drill hole RC13-220, a 200 meter plus offset to the north reported herein. Figure 3 shows an E-W section looking through RC13-220 and RC13-224 which appear to link the down-dip mineralization of the Ruby Creek zone with the South Reef zone into one continuous stratiform high-grade underground zone open to the north.

Current resources at Bornite (before the 2013 drilling), filed as an NI 43-101 technical report on SEDAR and EDGAR on February 11, 2013, are reported for the near surface, potentially open pit, resource as containing Indicated Resources of 6.8 million tonnes at 1.19% Cu for 178.7 million pounds of contained copper and Inferred Resources of 47.7 million tonnes of 0.84% Cu for 883.2 million pounds of contained copper at a 0.5% copper cutoff grade. Resources for the potentially underground exploitable resources at the South Reef zone are reported as containing Inferred Resources of 43.1 million tonnes at 2.54% Cu for 2,409 million pounds of contained copper at a 1.0% copper cutoff grade. An updated resource estimate for the Bornite Project and NI 43-101 technical report are anticipated to be completed during the first quarter of 2014.

Copper mineralization at the Ruby Creek and South Reef zones are hosted within broad dolomitized limestones within the Devonian-age Bornite Carbonate Sequence. Mineralization is selectively developed in massive dolostones and both sedimentary and hydrothermal breccias. The mineralized system is strongly zoned with a distal zinc-rich pyrite halo surrounding progressively more proximal chalcopyrite stockworks and disseminations, bornite stockworks and disseminations, and finally, local semi-massive sulphide zones of chalcocite, bornite, and chalcopyrite.

Quality Control

The drill program and sampling protocol were managed by qualified persons employed by NovaCopper.  The diamond drill holes were typically collared at HQ diameter drill core and reduced to NQ diameter during the drilling process. Samples were collected using a 0.5-meter minimum length, three-meter maximum length and 1.5-meter average sample length. Drill core recovery averaged 90%.  Three quality control samples (one blank, one standard and one duplicate) were inserted into each batch of 20 samples.  The drill core was sawn, with half sent to ALS Chemex in Fairbanks for sample preparation and the sample pulps forwarded to ALS's North Vancouver facility for analysis. ALS Minerals in North Vancouver, B.C., Canada, is a facility certified as ISO 9001:2008 and accredited to ISO / IEC 17025:2005 from the Standards Council of Canada.  NovaCopper will also be submitting 5% of the assay intervals from prospective lithologies to an independent check assay lab.

Qualified Person

Scott Petsel, P.Geo, UKMP Project Manager for NovaCopper, and a Qualified Person as defined by NI 43-101, has reviewed the results of the drill program and confirmed that all procedures, protocols and methodologies used in the drill program conform to industry standards. Mr. Petsel has approved the contents of this press release.

About NovaCopper

NovaCopper Inc. is a base metals exploration company focused on exploring and developing the Ambler mining district in Alaska.  It is one of the richest and most-prospective known copper-dominant districts located in one of the safest geopolitical jurisdictions in the world. It hosts world-class VMS deposits that contain copper, zinc, lead, gold and silver, and carbonate replacement deposits which have been found to host high-grade copper mineralization. Exploration efforts have been focused on two deposits in the Ambler district - the Arctic VMS deposit and the Bornite carbonate replacement deposit. A National Instrument 43-101-compliant Preliminary Economic Assessment for the Arctic Deposit, completed in July 2013, identified a polymetallic open-pit project with the Net Present Value of $930 and $535 million on the pre-tax and after-tax bases, respectively using an 8% discount rate and long-term metal prices of $2.90/lb copper, $0.85/lb zinc, $0.90/lb lead, $22.70/oz silver and $1,300/oz gold. 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 reserves.  There is no certainty the Preliminary Economic Assessment will be realized. Both deposits are located within NovaCopper's land package that spans approximately 143,000 hectares. NovaCopper has an agreement with NANA Regional Corporation, Inc. (NANA), an Alaskan Native Corporation that provides a framework for the exploration and potential development of the Ambler mining district in cooperation with the local communities. Our vision is to develop the Ambler mining district into a premier North American copper producer.

Cautionary Note to United States Investors

The PEA 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 the PEA 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 therein 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 in the PEA may not be comparable with information made public by companies that report in accordance with U.S. standards.
