QUEBEC – With the recent filing of the 43-101 report and pre-feasibility study for its Lac a Paul phosphate project in the Saguenay-Lac-St-Jean area, owner Arianne Resources of Chicoutimi, QC, is contemplating the production of a 38% P2O5 apatite concentrate at a rate of 2 million or perhaps 3 million t/y.
The 43-101 report puts measured and indicated resources at 348 million tonnes grading 6.50% P2O5. There is also an inferred resource of 114 million tonnes at 5.46% P2O5. Combined reserves in the Paul and Manouane zones, both of which are amenable to open pit mining, are 207 million tonnes grading 6.59% P2O5.
Arianne is now studying the idea of upping the annual production to 3 million tonnes (50,000 t/d) from 33,000 t/d. The increased rate could be reached by committing in the neighbourhood of $775 million to the project, 20% higher than earlier figures. Recovery and sale of titanium in an ilmenite concentrate is also possible. A feasibility study including these options is due in Q2 2012.
The Lac a Paul project is operated by Canada Phosphate (CanadaPhosphate.com), a wholly owned subsidiary of Arianne (Arianne-inc.com).
