Mineral Resource Estimate Criteria
The Initial Mineral Resource Estimate for the Isortoq Project was prepared by Andrew Turner, P.Geol. and Steven Nicholls, MAIG, both with APEX Geoscience Ltd. The inferred resource is based upon the results of an 11 hole (2,671 m) core drilling program that was completed by WMM in the spring of 2012. The program was conducted under the direct supervision of Mr. Turner of APEX. All samples were shipped for analysis to an accredited laboratory in Canada. The samples underwent standard preparation techniques and were analyzed by ICP, XRF and S-Leco techniques. A comprehensive QA/QC protocol with respect to all analytical and non-analytical data was implemented. For the analytical procedures, this included the insertion and monitoring of standard, blank and duplicate samples into the stream of regular drill core samples. No issues were noted with respect to sample security or analysis.
The resource model was generated using all 11 diamond core holes, with an average drill-hole spacing of 100 m. The deposit was geologically modeled using a combination of surface information from mapping work and sub-surface information where the troctolite intrusive (rock containing Fe-Ti-V mineralization) was observed to be in sharp contact with host granitic rocks. The Isortoq deposit was modeled as a long, NNE striking, steeply (approx. 90 degrees ) dipping dyke-like body and is limited to between 100 m and 250 m below surface, extending 950 m along strike (680m from the northernmost drill-hole to southernmost drill-hole) with widths up to 200m perpendicular to strike. The mineralized body remains open along strike in both directions.
The Isortoq drill database consists of 888 composited samples, each 2 metres in length, with no capping levels applied. The mineral resource was estimated by Ordinary Kriging ("OK") within a three dimensional wireframe envelope described above. Anisotropic search ellipsoid distances and orientations were established by variography. The search ellipsoid ranges utilized a 150 m x 40 m x 15 m primary search range. Grade estimation was applied to 20 m x 20 m x 20 m parent blocks with sub-blocking to honor wireframe volumes. Block densities (specific gravity, or "SG") were also estimated by the OK process based on 2,209 field measurements that were collected using the water displacement method on single pieces of whole core selected every metre along the 11 drill holes.
APEX is satisfied that the mineralization has reasonable prospects for economic extraction as required by the CIM Guidelines.
The 41,900 hectare Isortoq Project is a large iron-titanium-vanadium prospect in southern Greenland. Previous drilling combined with geophysical results to date has confirmed a potential strike length of at least 16.3 kilometres with the mineralized body being open to the south. The property is favourably located on a deep, ice-free ocean inlet on the temperate southern coast of Greenland within 60 km of Narsaq and 100 kilometres from Narsarsuaq International Airport. The mineralization at Isortoq is similar to the Mapochs deposit in South Africa, which has been successfully exploited for a number of decades by Evraz Highveld Steel and Vanadium and its predecessors. Bench scale beneficiation tests completed by the project vendor on previous Isortoq core samples gave average concentrate grades of 48.7% Fe (62.6% FeO); 19.1% TiO2 and 0.32% V2O5 with acceptably low levels of penalty elements S, P, Si, Al. These are positive indicators that support the future economic potential of the project. West Melville is in the process of purchasing a 100% interest in the project from Hunter Minerals Pty Ltd of Australia.
