Updated Preliminary Economic Assessment adds resources and value to the R�nnb�cken Nickel Project

IGE Resources AB (OSE: IGE) today announced the completion of an updated Preliminary Economic Assessment for the R�nnb�cken Nickel Project, Sweden, which is wholly owned by its subsidiary Nickel Mountain Resources AB.  

The Preliminary Economic Assessment (PEA) was prepared by SRK Consulting (Sweden) AB of Skellefte�, Sweden (�SRK�) on behalf of Nickel Mountain Resources AB (the �Company�).  The Preliminary Economic Assessment (�PEA�) is considered by SRK to conform to the Canadian regulations of National Instrument 43-101 Standards of Disclosure for Mineral Projects.

HIGHLIGHTS:

  • Average annualized production of 26,000 tonnes of nickel and 760 tonnes of cobalt in concentrate based on an annual feed throughput of 30 million tonnes
  •  A Life of Mine (�LOM�) of 19 years with a potential for this to increase following the delineation of further resources by ongoing exploration.
  • Low stripping ratio of 0.72:1 (waste tonnes:ore tonnes)
  • High grade sulphide concentrate containing 28% nickel
  • Average LOM Mine Gate Operating Cost of US$4.16/lb (US$9,171/t) of nickel recovered to concentrate
  • Average LOM C1 Cash Operating Cost of US$5.55/lb (US$12,200/t) of payable nickel net of by-product credits
  • Estimated Start-up Capital Cost of US$1,161 million, including working capital.
  • Pre-tax NPV8% ranges from US$316 million to US$1,572 million between nickel prices of US$9.00/lb and US$12.00/lb generating an Internal Rate of Return (�IRR�) and cashflow range from 12.4% to 26.6% and from US$1,701 million to US$4,498million respectively. 
  • Further assessment of technical viability and economics of recovering magnetite from flotation tailings has the potential to further improve the economics of the Project.
  • The Company is aiming to complete a Pre-Feasibility Study on the Project by mid-2012.
  • Excellent infrastructure with close access to hydropower, power grid, roads, seaport and airport.
  • Application of conventional mining and processing technology provides for low technical risk
  • Low sulphide content and presence of buffering minerals reduce risks of environmental impact
  • Sweden has a long established mining industry fostered by low royalties (0.2%)

LOCATION & REGIONAL INFRASTRUCTURE

The R�nnb�cken Nickel Project is located in the northwest part of Sweden, about 30 km to the south of T�rnaby, V�sterbotten County.  The Project currently comprises three discrete deposits: R�nnb�cksn�set, Vinberget and Sundsberget.

The local resources and regional infrastructure include a connection point to the Swedish national grid less than 4 km away and the Ajaure hydro power plant, rated for 85 MW, located upstream of Lake Gardiken and approximately 12 km from the Project site by gravel road.  European route E12 is 14 km from the Project site, running in a southeast-northwest direction connecting Storuman to the port of Mo i Rana in Norway, 148 km from Project site.  The nearest rail access is at the town of Storuman, 127 km to the southeast. Finally, there is an airport at T�rnaby, 40km to the northwest, with daily scheduled flight service from Stockholm.

OPERATIONS

The PEA assumes that mining will take place concurrently from two open pits with the full production rate of 30 million tonnes per annum (Mtpa) being achieved in Year 2. Ore production commences at R�nnb�cksn�set and Vinberget while the Sundsberget deposit is scheduled to commence in Year 5 and is in full production by the time the Vinberget deposit is depleted.  This will ensure a consistent supply of ore to the processing plant. Mining will be a conventional open pit drilling, blasting, shovel, and truck operation and will most likely be contracted out.

The currently proposed processing flow sheet comprises crushing, grinding, flotation, and dewatering typical of  concentrator operations in Sweden and Finland. The conceptual concentrator design, together with associated capital and operating cost estimates, has been prepared by Outotec AB (Sweden). The mill will have a capacity of 30 million tpa or 3,750 tonnes per hour, and will produce approximately 95,000 tonnes per year of nickel concentrate at a mean grade of 28% Ni which will be transported from site to port via road.

ECONOMIC ANALYSIS

SRK has constructed a pre-tax, pre-finance Technical Economic Model (TEM) to derive a Net Present Value (NPV) for the R�nnb�cken Nickel Project.  The economic analysis has been undertaken using US Dollar (US$) as the base currency. Any Swedish Krona (SEK) or Euro (EUR) derived costs have been converted at the exchange rates indicated in Table 1 below, which summarises all of the key financial assumptions made. Table 2 to Table 5 similarly summarise the technical and cost assumptions made and derived by SRK.

SRK notes in the PEA that its analysis is partially based on inferred resources and is therefore preliminary in nature.  Notably, inferred resources are considered too geologically speculative to be categorized as mineral reserves and there is no certainty that these will be converted to mineral reserves in due course or that the development, production, and economic forecasts on which the PEA is based will be realized.

No capital costs have been assumed for mining equipment as mining is assumed to be undertaken by a contractor.  The estimate provides a summary level of the pre-production capital required for a 30 million t/a nickel concentrator, and includes the costs for the concentrator building, ancillary buildings, tailings dam, and the infrastructure including access roads and power line. 

CASH FLOW PROJECTION AND SENSITIVITY ANALYSIS

SRK�s NPV has been derived by the application of Discounted Cash Flow (DCF) techniques to the pre-tax, pre-finance cash flow.

A sensitivity analysis of the Project is included in SRK�s report to reflect various alternative scenarios.  Table 6 below presents the Project valuation sensitivity under various nickel price scenarios

MINERAL RESOURCES

Table 7 below presents an updated Mineral Resource Statement for the Project as a whole, combining the SRK statement for R�nnb�cksn�set and Vinberget, and an estimate produced by the Mitchell River Group for Sundsberget, which SRK has audited. As is typical of ultramafic-hosted disseminated nickel sulphide deposits, nickel is contained both in nickel sulphides and in silicates such as olivine and pyroxene. Conventionally with these deposits the reported nickel grades and recoveries are �Total Ni� which incorporates both the nickel in sulphides and silicates. For R�nnb�cken however, an analysis of the nickel in sulphide has been carried out through the use an analytical technique utilising a weak acid digest (hence the term Ni-AC). This has enabled evaluation of the project based on the metallurgical performance of the nickel in sulphides only, rather than considering the deportment of nickel in both sulphides and silicates. The rational is that a high proportion of the sulphide nickel is recovered in the flotation process whereas the non-sulphide nickel reports predominantly to tailings. The Ni-AC results here are referred to in this Executive Summary report as �Sulphide Ni� grades and recoveries.

Table 8 presents the iron resource for the Project. This has been classified as Inferred to reflect the current preliminary status of the mineralogical work. Specifically, in SRK�s opinion, more information is required to be collected to enable the proportion of the total Fe that has potential to be recoverable in a concentrate to be determined to the level of confidence required by a higher category.    

Both are presented according to CIM Guidelines for the reporting of Mineral Resources.

ENVIRONMENTAL CONSIDERATIONS

There are four types of permits necessary to develop a deposit from the exploration stage to the development stage in Sweden. These are: exploration permits, exploitation concessions, environmental permits and building permits. The Company holds exploration permits for all three deposits Exploitation concessions have been granted over the Vinberget and R�nnb�cksn�set deposits, supported by environmental impact assessment studies. An application for exploitation concession for the Sundsberget deposit is expected to be filed in second quarter of 2011 and applications for environmental and building permits, are planned to be submitted to the regulatory authorities in third quarter of 2012 and first quarter 2014, respectively, supported by the appropriate studies in each case.

NEXT STEPS

The Company is now proposing to undertake a Pre-Feasibility Study on the Project, with targeted completion by mid-2012 at a budgeted cost of US$23.4 million.

Subject to the results of the Pre-Feasibility Study, the Company then expects to commence a full feasibility study in the second half of 2012 for completion towards the end of 2013 and has developed a preliminary budget for this work of US$68 million.

SRK CONCLUSIONS AND RECOMMENDATIONS

SRK has recommended that:

  • Further assessment of the technical viability and economics of recovering of magnetite from the flotation tailings be undertaken as this has the potential to significantly improve the economics of the Project.
  • Exploration drilling be continued to evaluate the potential that still exists within the existing exploration permit areas.  Notably, in addition to target areas which are separate from the three currently identified resource areas, the R�nnb�cksn�set and Sundsberget deposits remain open at depth.

SRK also concluded that the Pre-Feasibility Study is justified by the potential of the Project and that the timing and budgets proposed for this by the Company are reasonable given the work planned to be undertaken. Further, whilst the justification for a full Feasibility Study following this will be dependent upon the results of the Pre-Feasibility Study, SRK noted that the preliminary budget proposed for this is of the correct order of magnitude for a Project of this nature and location.
