A detailed breakdown of the constituent Rare Earth Element Oxides forming the basis of the TREO grade reported above 1.0% TREO and 5.8% TREO is presented in Appendix 1.
As can be seen from Figure 1 below the Initial Total Rare Earth Oxide Resource Estimate for Mrima Hill shows the deposit is of global significance in terms of scale and grade.

As can be seen in the plan above there is a large zone of high grade niobium and rare earth mineralization with the majority outcropping on the surface of Mrima Hill.
Mineral Resource Estimate Methodology
The geological setting is defined as a carbonatite and vent agglomerate of Cretaceous age intruded into a fault bounded basin of Jurassic sediments. The carbonatite lithologies are classified as sövite, alvikite and beforsite. Historical surface mapping was used to define the lateral extents of the carbonatite. Mineralisation is associated with the highly weathered clays and saprolites forming a deep weathering profile due to the high carbonate content and related ease of weathering.
RC drilling formed the majority of holes (75%) and employed a 140mm face sampling hammer and consisted of 55 drill holes for 3,413 metres. Diamond drilling using HQ3 diameter core was also completed and comprised 14 holes for 1,649 metres. Drilling is broadly irregular although some zones are approaching a regular drill spacing of a nominal 50m (northing) by 50m (easting). All drill holes were geologically logged and included details on lithology, mineralogy and weathering. Additionally any observable structural features in the diamond core were also recorded. Estimates of sample recovery were based on recovered intervals for diamond core and a combination of recovered mass and qualitative assessment for RC drilling. Drill collars were surveyed using high accuracy GPS and downhole surveys were conducted using single and multi-shot down hole cameras. Density measurements using immersion method were taken on 291 core intervals representing various lithologies and weathering states.
Diamond core was sampled on nominal one metre intervals and constrained to geological intervals where appropriate. Samples were taken by cutting the core along its axis (half core) and submitting for analysis. RC samples were collected exclusively on one metre intervals and riffle split at the drill rig to achieve a nominal 1 to 3kg sample. Field QAQC procedures included the insertion of blanks and collection of field duplicates at a rate of 1 in 20 (5%).
Samples were transported to Nagrom Laboratories in Perth, Western Australia where they were dried, crushed and pulverised to achieve 85% passing 75 micron. Sample pulps were then submitted to Ultra Trace Laboratories in Perth for determination of niobium by XRF and to Genalysis Laboratory Services for determination of rare earth elements by ICP-MS.
A three dimensional mineralisation envelope was constructed for the niobium mineralisation using a lower cut-off grade of 0.2% Nb2O5, with an additional high grade niobium envelope constructed using a 1% Nb2O5 cut-off. The niobium interpretation utilised the historical Anglo American test pit data to constrain the interpretation, however these assays were excluded from the final resource estimation. The rare earth oxide mineralised envelope was created using a 1% TREO cut-off grade. These interpreted solids were used to flag blocks within the resource model for estimation. The mineral resource area is constrained to the granted mining license and forms an irregular shape with approximate dimensions of 1,500m (north) by 900m (east) by 250m (depth).
Samples were composited to one metre lengths and statistical analysis showed relatively low coefficients of variation with no clear outliers and as such no top cuts were applied to either the niobium or rare earth domains. Directional variograms and search ranges were developed for niobium and total rare earth oxide (TREO) grades and applied to all elements within the respective domains. Blocks were estimated using Ordinary Kriging with an ellipsoid search.
The block model used a parent cell size of 50m(X) x 50m(Y) x 5m(Z), with blocks sub-celled to a minimum of 12.5m(X) x 12.5m(Y) x 1.25m(Z) to support accurate representation of contained volumes, with all interpolation carried out on the parent cell size. Kriging neighbourhood analysis was employed to optimise estimation parameters, and estimation was completed using three passes. Block model validation shows acceptable correlation between assays and estimated block grades.
Classification of the Mineral Resource has considered the drill density, geological and grade continuity, estimation statistics, and model validation results. This has resulted in those areas with regular drilling being assigned an Indicated category, while the remaining areas have been assigned as Inferred.
Closing Comments
PAW President and CEO, Mr. Darren Townsend, commented, "We are very pleased with this high grade resource estimate which confirms the Mrima Hill Niobium and Rare Earth Project to be a world class deposit in two metal suites. This combined with our recent success in achieving a 90% metal dissolution for Niobium and 99% for Rare Earths in Metallurgical test work bodes well for the future. We look forward to rapidly advancing the metallurgical work and completing the Preliminary Economic Assessment for the Project by the end of 2013."
