G&G Concern-Sulphur

[rpdeluca]

At one point, G&G was pointing out something in regards to the Sulphur content of RB and what a concern it was and the lousy iron ore that you would get from this. You know one of his so called "know it all" posts.  Here is a little section from the latest Techincal Report if anyone had any concerns about the Sulphur content at RB.  Oh and by the way, I would like to point out one word   WRONG

Five (5) composite samples (100 kg ore; bullet 1 above; with ore cut-off grade of 25%Fe) were sent to the
Changsha Research Institute of Mines and Metallurgy (CRIMM, China) in order to qualify the responses of
the Roche Bay Iron Project ores to the crushing, grinding, magnetic separation (dry and wet) and sulphide
flotation processes. The development of the optimal process flowsheet was required. The results of the
CRIMM tests confirmed the previous test results developed by SGS, COREM and SGA for the obtaining of
an iron concentrate with a minimum 65% Fe, maximum 5% SiO2, maximum 0.05% S and -0.03 mm size.
The ore processing flowsheet proposal is in accordance with the process flowsheet selected by AEI and
Wardrop and will be outlined in detailed in the FS to be published in 2012.
13.3.1 Conclusions (Metallurgical Tests)
The test results obtained by all laboratories mentioned above revealed the following aspects:
1.  From the Roche Bay Iron Project magnetite ores, an iron concentrate 65% to 68% Fe, maximum 5% SiO2,maximum 0.07% S and maximum 0.05% P can be profitable obtained by wet magnetic separation andsulphide flotation.
2. The hardness of the Roche Bay Iron Project ores is relatively low (Bond Work Index 9 to 11 kWh/t) and,
consequently, the comminution processes (crushing and grinding) are characterized by relatively low
energy consumption.
3. The high dissemination of the magnetite and aimed concentrate chemistry requires a fine grinding size, of 0.03 to 0.035 mm (P80) or 400 to 440 mesh.
4.This fine final product, based on its chemistry and size, is an excellent iron concentrate for pelletizing
process.
5. The concentration process is characterized by a high efficiency (weight and iron recoveries).
6. The weight and iron recoveries are 27% to 41% and 66% to 82%, respectively, in function of the ore iron
grade level.

The Roche Bay ore in the C-zone has 0.7% sulphur. This is high compared to most deposits worldwide (compare to Labrador Trough deposit). Their ongoing metallurgical testing program is focused on developing a process flow sheet, using sulphur flotation, that will create a final product with 0.07% sulphur. They may or may not be ultimately successful. The DFS, once it's delivered

Please verify who has stated (otther than yourself) that Sulphur was a concern and remains a concern?  Is this indicated in the Technical Report?  Did one of the geologists state this? 

[Greenandgold.]

The March 2nd technical report spends about 20 pages on metallurgical testing and the sulphide flotation process to reduce the 0.7% sulphur present in the raw ore to 0.07% sulphur in the final product. If sulphur's not a concern for AXI then why is Golder writing so much about it? Why is Wardrop running so many metallurgical tests trying to figure out the optimal solution to the

That's what a technical report is suppose to do.... Frankly I don't care what the sulphur level is and you will grasp at anything to try and twist and turn this little ship called AXI.  At the end of the day, whatever processing is required for this and whatever cost is associated with this is factored into the NPV calculation and IRR.  The report clearly states that there are no

[Greenandgold.]

Nobody's twisting anything. The 0.7% sulphur level in the Roche Bay C-zone ore is a fact. Sulphide flotation being a necessary part of the process flow sheet is a fact.  * If the DFS, when it's delivered, puts up an NPV above $1 billion for Roche Bay, then AXI will get that credit. Not before then. AXI's internal cost estimates for Roche Bay capex are ridiculously

One more post from me on this Sulphur debate. With respect to sulphur......it doesn't matter what the in ground grade of the sulphur is, when your metallurgy has proven a superior finished marketable product [0.07% S], that is proven economical by way of the low OPEX.....through whatever processes are necessary.It's as simple as that!  I don't care if the sulphur is 0.9% or 2.0%.&
