Anfield Receives Excellent Preliminary Results From Its Metallurgical Testing Program at Its Mayaniquel Project, Guatemala

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 8, 2010) - Anfield Nickel Corp. (TSX VENTURE:ANF) ("Anfield") is pleased to announce that it has received preliminary results from its metallurgical testing program on its 100% owned Mayaniquel nickel laterite project in northeastern Guatemala. Based upon the samples tested, results show that metallurgical recoveries of between 90% and 94% are potentially achievable to produce a ferronickel alloy product grading between 20% and 33% nickel. A ferronickel alloy product containing 22% nickel is generally preferred by stainless steel producers.

The preliminary testing program, undertaken at Mintek's laboratory in Johannesburg, South Africa, was conducted on bulk samples from the Inicio deposit at Sechol. Nine individual samples were chosen primarily from pits, but supplemented with drill core. Material was collected from the 3 laterite lithologies found at Mayaniquel (limonite, transition and saprolite) and targeted low, medium, and high nickel grades from the three lithologies. These samples were subjected to a series of physical characterisation and chemical composition tests from which five blends were derived using a predictive metallurgical smelting model for the smelting test work. The five blends consisted primarily of saprolite material (low, medium and high grade) with varied additions of transition and/or limonite material to simulate variations in ore feed compositions that may be encountered during the mining and smelting process.

The five blends prepared for smelting tests had the following chemical characteristics.

  Blend 1 Blend 2 Blend 3 Blend 4 Blend 5
Ni head grade % (dry basis) 1.60 1.30 1.29 1.59 1.98
Fe/SiO2 0.56 0.37 0.33 0.61 0.50
SiO2/MgO 1.75 1.71 1.57 1.60 1.52
Fe/Ni 11.97 10.53 9.47 11.69 8.18

A series of 61 laboratory smelting tests were conducted on the five blends (calcined) using various carbon and flux additions to evaluate their smelting behaviour (specifically with regard to carbon requirement and Ni recovery). Ferronickel alloys were successfully produced from all five blends.

The results from the smelting test work confirmed that the predictions from the metallurgical smelting model are reliable and a ferronickel alloy containing 26% to 33% Ni can be achieved at a Ni recovery of 90%, while for a nickel recovery of 94%, alloy grades ranging between 20% and 26% Ni are predicted.

The preliminary results of the smelting test work on the 5 blends conclude that the following ferronickel alloy products could be expected to be produced based upon a nickel recovery of 93% and an associated iron recovery of 27.5%.

  Blend 1 Blend 2 Blend 3 Blend 4 Blend 5
Ni head grade % (dry basis) 1.60 1.30 1.29 1.59 1.98
MWh/t calcine* 0.452 0.442 0.437 0.457 0.440
Ni recovery % 93 93 93 93 93
Alloy grade, % Ni 22 23 25 22 28

The Mintek report accompanying the metallurgical results states that the results of the preliminary testwork "imparts a high level of confidence with respect to the amenability of [the Mayaniquel] samples to produce ferronickel at a commercial scale. Optimising the ore blending is shown to be of importance, as is typical for laterite smelters, due to the inherent variability of these types of ores. Selective mining, blending and good plant practices were shown to be important factors [in producing the appropriate ferronickel alloy]."

The metallurgical testing program is now focused on determining the appropriate materials handling solutions for the Mayaniquel material including evaluating the amenability of the material to physical upgrading. Once completed, the metallurgical and materials handling testing programs will be expanded to evaluate nickel laterite material from Nueva Caledonia, Nueva Concepcion, Chiis and Tres Juanes.

The Mayaniquel project comprises mineral exploration licenses totaling approximately 80,000 hectares in the nickel laterite belt surrounding Lake Izabal, 120 kilometers northeast of Guatemala City. Anfield's mineral exploration licenses lie adjacent to the "Fenix Project" owned by Compańia Guatemalteca de Niquel S.A., a subsidiary of HudBay Minerals, Inc.

On April 9, 2009, an independent NI 43-101 mineral resource estimate was prepared on the Mayaniquel project as shown in the table below:

Mineral resources do not have demonstrated economic viability.
(1)The Transition zone is a mixed horizon of limonite and saprolite material and was defined using both geological logging data and chemical analysis.
(2)The Saprolite zone represents the lower part of the laterite profile below the Transition zone and was defined using both geological logging data and chemical analysis
(3)DMT – dry million tonnes.
(4)Chiis is a zone within Nueva Concepcion.

In January 2010, Anfield initiated a 44,000 meter drill program at the project. The program is focused on expanding current NI 43-101 mineral resources at the Sechol and Nueva Concepcion/Chiis deposits and delineating new resources at the Nueva Caledonia, Tres Juanes and San Lucas target areas.
