Pegmatite Anatomy
The Main Sill is zoned, generally with an albite-rich (50-90%) wall zone at both contacts with
quartz. The albite wall zone is comparatively thin, generally less than one metre
A K-feldspar zone usually with some quartz bands, green mica and lesser albite contacts the
albite wall zones although it isn’t everywhere present.
These zones enclose a central, banded spodumene-quartz core zone with concordant
subzones in the form of feldspar-rich bands, most commonly dominated by albite but
generally mixed with K-feldspar, quartz and dark green mica. Chains of coarse K-feldspar
crystals also occur in the zone.

•2004 JORC Code was followed for Mineral Resources.
•Mineral Resources are estimated using an average price of US$350 per tonne of spodumene concentrate and a US$/C$ exchange rate of 1:1.00.
•Totals may not represent the sum of the parts due to rounding.

2011 program objectives include:
• Characterising the mineralogy and metallurgical performance of the Moblan
pegmatite
• Developing a conceptual flow-sheet for ore processing
• Developing a preliminary mine plan
• Estimate of preliminary capital and operating costs to ±25%
• Completing a preliminary mine and infrastructure geotechnical assessment
• Preliminary tailings site location and conceptual design
• Background socio-economic and environmental studies
• Develop preliminary marketing plan
Jointly develop a pre- development agreement with the Cree Nation of
Mistissini to set out various undertakings of the parties during exploration
and pre-development activities and provide the basis for the negotiations of
an Impacts and Benefits Agreement.
