Positive Pelletizing Tests from Stora Sahavaara
Vancouver, February 15, 2007: Buck Morrow, the President of Northland Resources Inc., is pleased to report that the Company has received very encouraging results from recent bench-scale pelletizing test work supervised and performed by Hazen Research, Inc. of Golden, Colorado in the US, and Metso Minerals of Danville, Pennsylvania, also in the US. The work was performed to define the parameters of the kind of pellet that could be produced from Stora Sahavaara magnetite with the least amount of processing.
A magnetite concentrate was made from a single magnetic separation of crushed and ground Stora Sahavaara drill core, and the magnetite concentrate was then palletized, producing a commercial quality pellet. No flotation was carried out prior to the pelletizing. According to Metso, the pellets produced by this process are of good quality.
The following table compares the concentrate and pellet analyses:
Concentrate Grade %
Final Pellet Grade %
The concentrations of iron, sulfur, silica, P2O5 and MgO are all within commercially acceptable limits for iron ore pellets (the MgO concentration is acceptable for flux pellets and additional magnetic separation phases should reduce the MgO content). Conversion of magnetite to hematite in the pelletizing processes reduces the Fe % as does the addition of the bentonite to make the pellet.
Management believes that the iron concentration, and the overall composition of the pellets, are likely to improve further by using a better magnetic concentrate in the pelletizing process. For example, a pellet feed similar to the one produced by the flotation work done at SGS Lakefield (see Northland's news release dated February 12, 2007) will yield an even better quality pellet.
Buck Morrow, President of Northland, said: "The results of Hazen's test work back up what we are seeing in the work that Corus has been carrying out, which we released earlier this week. As our test work program moves forward, we're gaining confidence that we will be able to produce a commercial grade pellet from Stora Sahavaara magnetite."
Northland supplied roughly 1,500kg of magnetite material from 4 large diameter core holes drilled in 2005. The sample was a composite of magnetite mineralization from several holes through the mineralized zone. The Fe head grade ranged between 48% and 52.3% total iron with a weighted average grade of 50% Fe. The sulfur grade of the head sample was 2.77%.
The material was ground to 90% passing 74 microns. Ground material was passed over an 8 inch bench scale wet drum magnetic separator and two products were produced: one magnetic and one non-magnetic. The composition of the magnetic concentrate is shown in the table above. The magnetic concentrate was subsequently fired in a kiln at 1,300°C and SO2 was captured in a scrubbing system.
Hazen's sulfur analysis of fired pellets from Metso assayed 0.01% and the Metso report stated that the pellets were of good quality.
The grinding, magnetic separation, and assays were performed; and final report was compiled by Hazen Research, Inc. of Golden, Colorado, under the supervision of Roland Schmidt, Director, Mineralogical Laboratories, and has been reviewed by Phillip M. Rooke, P.E. of Hazen, a Qualified Person as defined in NI 43-101.
