Add Chromite to the McFauld’s mix page 14. Mining Markets Sept. 2008
"Ever since Noront Resources (NOT-v) discovered high grade nickel at its Double Eagle project last September, most of the speculation about the area’s mineral potential has focused on nickel copper deposits similar to those being mined at Voisey’s Bay in Labrador.
But the area’s potential to host economic chromite deposits may be equally important. In late May, Noront announced that it had discovered a thick layer of massive chromite (rock composed largely of the mineral chromite) lying about 30-50 metres beneath the Eagle Two copper-nickel deposit. The steeply dipping layer, now called “Blackbird” One to differentiate it from the “Eagle” nickel-copper depositis, was traced by drilling from near surface to depths of up to 400 metres at widths of up to 69 metres. One intersection returned 50 metres average 39% Cr2)3.
The find is significant because not only are the grades comparable to those being mined in South Africa’s Bushveld Complex, which holds about 70% of the world’s total chrome reserves, but the widths appear to be thicker. In the Bushweld, the majority of deposits lie in two main layers, 0.6 to 1.3 metres thick. At Blackbird One, the seams vary from a few centimeters to more than 20 metres in true thickness.
Overall, the Bushveld Complex contains more than 1 billion tones of reserves grading 42-45% Cr2O3.
The only known Canadian chromite deposits are the Bird River Sill deposits in Manitboa, which mainly occur within a 3-metre layer and are too low a grade ( 21% Cr2O3) to be considered economic.
Chromite is used to make ferrochrome used in stainless steel. It would be an understatement to say that the economics of the ferrochrome market are robust. Chrome exports to China more than doubled to almost 1 million tones in 2006 and forecasts show Chinese stainless steel demand growing by 7-10% per year to 2020. Prices have increased several fold from US. 0.63 lb in early 2006, to US 5.50 per lb. recently for extra-low carbon ferrochrome.
An important consideration when evaluating chromite deposits is the ratio of chrome to iron. Ideally, the chrome-to-iron ratio should be at least 1.5 to produce ferrochrome. At Blackbird One, chrome-to-iron ratios average 1.7 compared to about 1.9 in the Bushveld and 1.4 at Bird River."
