Anfield Announces Positive Results of Prefeasibility Study on Mayaniquel Nickel Project
(firmenpresse) - VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 10/24/12 -- Anfield Nickel Corp. ("Anfield") (TSX VENTURE: ANF) is pleased to announce the results of a Prefeasibility Study (the "PFS") on its 100% owned Mayaniquel nickel project located in northeastern Guatemala (the "Project"). The results of the PFS, which has considered significantly higher mining and processing rates (average 36,500 tonnes per year of nickel over the life of the mine) due to the addition of a second rotary kiln electric arc furnace unit in the fifth year of production compared to the 2011 Preliminary Economic Assessment ("PEA") (average 19,900 tonnes per year of nickel), demonstrates that a ferronickel operation at Mayaniquel is economically viable and the Project should be advanced to a feasibility study. Highlights of the study's various estimates are as follows (all dollar figures in US dollars):
Highlights
The salient details of the PFS are summarized in the table below (all dollar figures are in US dollars):
Note: The 2011 PEA is preliminary in nature and includes the use of 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. Thus, there is no certainty that the PEA will be realized. Actual results may vary, perhaps materially. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
Anfield will host a conference call on Wednesday October 24th, 2012 at 11:00 am (Pacific Time) or 2:00 pm (Eastern Time) to discuss these results. Call-in information is provided at the end of this news release.
The PFS was supervised by Mr. Neil Prenn, P.E., an independent qualified person. Mr. Prenn has reviewed and approved the contents of this news release. The PEA was managed by MTB Project Management Professionals, Inc. (project management, infrastructure, ancillary capital and operating costs and cash flow modeling) and comprised several studies prepared by: SIM Geological Inc. and BD Resource Consulting, Inc. (resource estimate and model, quality assurance, quality control program); Neil Prenn, P.E.

Project Economics
MTB Project Management Professionals, Inc. developed a cash flow valuation model for the Project based upon the geologic and engineering work completed to date. The Base Case was developed using a long term forecast nickel price of $8.50/lb. This price forecast is lower than the consensus long term forecast of approximately $8.94/lb nickel made by 23 banking analysts. In addition, a by-product credit of $0.18/lb iron contained within the ferronickel product has been included in the Base Case.
The following table shows the NPV of the Base Case and the Analyst Case at various discount rates:
The following chart shows the sensitivity of the Base Case's NPV (8% discount rate) and IRR to changes in the nickel price: .
Mineral Resources and Reserves
Mine Development Associates used an updated mineral resource estimate (effective date of March 22, 2012) completed by Sim Geological Inc. and BD Resource Consulting, Inc. and the corresponding block model, to estimate the Project's mineral reserves and develop the mine plan and production schedule for the Project.
The Project's mineral reserves and mine plan were estimated using only those mineral resources contained within the measured and indicated categories. Inferred resources were treated as waste where applicable.
Floating cone analyses were used to determine the extent of laterite mining areas and the best sequence for economic development. The floating cone analysis, based on a nickel price of $5.00/lb, defined the mineral reserves, which were subsequently adjusted to conform to current concession boundaries. The resulting pit limits were then used to estimate the Project's mineral reserves, total waste of 27.6 million tonnes, mine plan and production schedule. This mine plan resulted in a LOM stripping ratio of 0.4:1.
The updated mineral resource estimate (at a 1% nickel cutoff grade) and mineral reserve estimate are shown in the table below:
The Program's quality assurance/quality control (QA/QC) program is monitored by independent consultant Dr. Bruce M. Davis, FAusIMM of BD Consulting, Inc. Logging and sampling are completed at Anfield's secure facility located at the project. Drill core is mechanically split on site with sample preparation completed at a facility at Anfield's exploration compound. Samples are prepared in accordance with ALS Chemex's standards with pulps subsequently shipped to their laboratory in Vancouver, Canada for X-Ray Fluorescence Spectroscopy analysis, the common analytical technique used in nickel laterite exploration. Quality from the on-site sample preparation lab is monitored by an independent, rigorous program including pulp and coarse-reject duplicates and analyzing cleaning materials from the crusher and pulverizer units to assure contamination-free sample processing. Anfield also inserts blanks and standards selected on a random basis into the sample stream and sends 5% of the sample pulps to a check laboratory in Vancouver, Canada. The results of this QA/QC program indicate that the Program's database of sampling, analytical and test data is of sufficient accuracy and precision to be used for the generation of mineral resource and mineral reserve estimates.
Mining & Processing
The Project will utilize conventional open pit mining methods and production is scheduled to mine approximately 9,000 tonnes per day (3.30 million tonnes per year) of lateritic ore to the plant for 22 years. Twenty four percent of the mined ore will be delivered directly to the processing plant, while the remaining mined material (2.5 million tonnes per year) will be sent to the upgrading plant, where low nickel grade and high iron material will be rejected, thereby providing the processing plant with a total average feed grade of 1.68% nickel LOM (1.85% average nickel grade over the first 3 years of production). The plant feed will be sent to a double line rotary kiln where it will be dried, calcined and partly pre-reduced with the addition of coal prior to being fed into one of two 80MW electric arc smelting furnaces and subsequent refining furnaces to produce the ferronickel product (for the first four years of operation, the plant will operate with a single line rotary kiln and furnace). The processing plant is forecast to produce approximately 162,000 tonnes per year of ferronickel over the mine's life containing approximately 36,500 tonnes of nickel at an average grade of 22.5% nickel at an average nickel recovery rate of 90%.
Capital Cost Estimates
IGEO Mineracao Inteligente, MTB Project Management Professionals, Inc., Ausenco Vector, MineSense Technologies and Mine Development Associates developed capital cost estimates for the proposed mining and ferronickel operation. The mine will start operating with one of the two 80MW rotary kiln electric arc furnace units built. In year 3, construction of the second 80MW rotary kiln electric arc furnace unit will start with production commencing from that furnace unit in year 5. The following table summarizes the capital cost estimates in the PFS for the Project:
The capital cost estimates have been compiled with an accuracy level of -15% to +25%.
Operating Cost Estimates
The results of the PFS show that a mine at the Project will be a low cost operation, with operating costs potentially averaging in the lower quartile of the industry cost curve(1). The Project benefits significantly from the low strip ratio, relatively easy terrain, positive metallurgy, and close proximity to major infrastructure. Based upon a comprehensive study of future power supply in Guatemala that has estimated long term power costs of between $0.06 and $0.09/kWh, the Base Case has assumed a long term power cost of $0.08/kWh. In addition, long term coal prices used in the Base Case were assumed to be $113/tonne (including freight). The PFS estimates that the C-1 cash costs (net of iron credits) over the life of the mine will average $3.05 per pound of nickel sold. C-1 cash costs include at-mine cash operating costs, royalties (BHP Billiton and government), mine reclamation and closure costs, and ferronickel transportation and freight costs ().

Infrastructure
Substantial regional infrastructure is in place within the vicinity of the Project. The Project is located within 70 kilometers of the Caribbean Sea and 166 kilometers by road from the largest port in Guatemala, Santo Tomas, thus facilitating the exportation of ferronickel and importation of coal and other consumables. In addition, major power infrastructure is within two kilometres of the Project. The local labour force is large and while not versed in mining and nickel processing, provisions have been made in the capital cost estimate to train the local labour force, with the assumption that labour drawn from within Guatemala will ultimately manage and operate the mine and plant facilities.
Environmental
The Project has been designed to meet World Bank Guidelines for social and environmental management practices. Baseline studies completed to date have included surface water quality, meteorological, air quality, noise, archaeological, social context analysis, stakeholder mapping, community health, community census, land-use, biological (flora and fauna) and re-vegetation studies. As the nickel deposits are largely soil based, mine waste material will be largely overlying topsoil and low grade limonitic soils. Provisions have been made within the mine plan and operating costs to account for the storage of both the topsoil and low grade limonitic soils and the recontouring and re-vegetation of mined areas with these soils once the deposits have been mined. It is expected that this process will allow the mined areas to largely return to their pre-mined state of vegetation.
Three Environmental Impact Assessments ("EIA") have been completed in support of the Exploitation Licence applications for the Project's mining areas (Sechol, Tres Juanes and Amanecer) and have been submitted to the Guatemala Ministry of Environment ("MARN"). The Sechol EIA was approved by the MARN in 2011 and the Tres Juanes and Amanecer EIA's were submitted to the MARN in October 2012.
Exploitation Licence Applications
Anfield has submitted three exploitation licence applications for the Project's mining areas to the Guatemala Ministry of Energy of Mines ("MEM"). Upon approval, the exploitation licences, which encompass all of the planned mining areas, will allow the Company to mine the mineral reserves for a period of 25 years from the time of approval with an option to renew the licence for an additional 25 year period. No date has been set for the approval of the exploitation licences but the Company expects them to be approved prior to the completion of a feasibility study on the Project.
Next Steps
With the completion of the PFS, Anfield is focused on working with the MARN to gain approval of the Tres Juanes and Amanecer EIAs and with the MEM to obtain approval for the exploitation licences.
A feasibility study will be initiated on the Project once Anfield has determined all of the necessary work requirements to complete the study, including infill drilling meterage required to convert inferred resources to the measured and indicated categories, additional metallurgical test work and the other engineering, logistics and infrastructure studies.
Anfield will also continue to work with the local communities and stakeholders around the Project focusing on further developing the environmental and social programs it has operating in the area.
