NI 43-101 Update (September 2012): 11.1 Mt @ 1.68% Ni, 0.87% Cu, 0.89 gpt Pt and 3.09 gpt Pd and 0.18 gpt Au (Proven & Probable Reserves) / 8.9 Mt @ 1.10% Ni, 1.14% Cu, 1.16 gpt Pt and 3.49 gpt Pd and 0.30 gpt Au (Inferred Resource)
I took another look at the grades at Royal Nickel land then I remembered some highlights at Noront's AT12. Noront's NR stated:
Preliminary estimates suggest that AT-12 averages 0.30 to 0.35% nickel, comparable to many nickel projects currently being evaluated for economic exploitation
BUT,
In Noront's NR the following was stated:
Establishing the geometry of the AT-12 ultramafic dike, specifically the plunge, will assist in our efforts to identify higher grade nickel-copper sulphide mineralization at the lower contact of the dike where irregularities allow pooling of the nickel-copper sulphide mineralization as observed in the cluster of drill holes at the north-northeastern limit of the dike where it intersects surface."
Royal's Nickel is between .26-.28 and the platium ranges in the .02 and palladium .009

TORONTO, June 28, 2011 /CNW/ - Noront Resources Ltd. ("Noront" or the "Company") (TSX Venture: NOT) is pleased to report final assay results from the 2010 /11 winter exploration program at the Company's McFaulds Lake Project in the James Bay lowlands, Ontario.

Noront's President and CEO, Wes Hanson, states: "The exciting discovery of pervasive nickel mineralization and establishing the geometry of the AT-12 ultramafic dike are very significant events. Preliminary estimates suggest that AT-12 averages 0.30 to 0.35% nickel, comparable to many nickel projects currently being evaluated for economic exploitation. The Company believes AT-12 may be amenable to bulk mining methods, which would significantly increase the life of our Eagle's Nest advanced development project and could potentially increase that projects throughput rate. Establishing the geometry of the AT-12 ultramafic dike, specifically the plunge, will assist in our efforts to identify higher grade nickel-copper sulphide mineralization at the lower contact of the dike where irregularities allow pooling of the nickel-copper sulphide mineralization as observed in the cluster of drill holes at the north-northeastern limit of the dike where it intersects surface."
2010-11 WINTER DRILL RESULTS
The Company completed 16 holes (8,006 metres) during the winter field season.
AT-12
Seven holes were completed at AT-12 to test geophysical anomalies identified from surface surveys.

The majority of the drill holes identified pervasive nickel mineralization within the ultramafic dike hosting the AT-12 mineralization. The core of the dike is an olivine-pyroxenite - peridotite that grades outward to pyroxenite at the margins. Nickel grades range from 0.20% to 0.70% nickel over core intervals ranging from several tens of metres to several hundred metres. Sampling correctly focused on areas where visible sulphides were observed in the core. Areas where sulphide mineralization was sparse were not routinely sampled resulting in gaps in the sampling record. The Company has identified additional intervals to eliminate the sampling gaps.
The identification of pervasive nickel in the 2011 drilling was supported by a review of the historical assay records at AT-12. This review identified a number of long nickel intercepts that had not previously been reported within the AT-12 dike.
Table 1 presents the results of the new composites from the historical drilling, the originally reported intervals of the historical drilling and the latest results from the winter 2010 - 2011 winter drill program.
The nickel mineralization at AT-12 has been traced by drilling for 1,400 metres along strike to an average depth of 600 metres from surface. The dike dips sub-vertically, averages 200 metres in width and plunges to the south-southwest at 60º to 70º. Nickel grades range from 0.2% to 0.7% within the ultramafic dike. The nickel mineralization at AT-12 compares favourably to a number of nickel sulphide deposits elsewhere in Canada and the USA in terms of both grade and size.
Higher nickel grades, in excess of 1.0%, previously reported in holes NOT-09-2G34 to 2G37 are localized at the north-northeast limit of the AT-12 dike where it intersects the topographic surface. Company geologists believe that this area may represent the lower contact of the AT-12 dike. Given the plunge to the south-southwest, the Company believes that exploration along the lower contact may yield additional high-grade nickel-copper sulphide mineralization as irregularities along the contact could create areas where nickel-copper sulphides mineralization could accumulate.
Spatial analysis of the AT-12 data confirms that the nickel mineralization is confined to the host ultramafic dike. The interpreted lower contact of the dike has only been drilled at the north-northeast limit where it comes to surface. Further drilling along the lower contact offers an excellent target for additional high-grade nickel, copper, platinum and palladium mineralization. The Company is planning a follow up exploration program during the upcoming winter season
