Arrowstar Completes Benefication Testing from 105 samples, at Port Snettisham, Alaska, Iron Ore Project


VANCOUVER, Dec. 11, 2012 /CNW/ - Robert L. Card, President of Arrowstar Resources Ltd., (TSXV: AWS), (the "Company") reports that the Company has  commissioned Inspectorate in Vancouver to complete an analysis of 105 rock samples (that included non-magnetite samples) that were categorized into two batches, the Piling group that is closely located to the ground magnetic survey high identified near claim 14 of the property and the Beach group located near Claim 24. Each sample was tested for Fe and other elemental contents and a Davis Tube test completed to determine the magnetic component of the iron. The results are tabulated below:

  • LOI is loss of ignition, Fe is Total Fe as analysed by XRF

The average Fe of 21% is typical for pyroxenite, and during operations a mining engineer will be testing the head grade to ensure it meets the cut off grade.  The S, P, SiO2 and Al2O3 grades on samples containing high Fe conformed with commercial grades.

Davis Tube Tests
The 105 samples were crushed and then tested for magnetic attraction to simulate going over a high speed magnetic drum in production.  Because of the diversity of the samples, this simulated the iron ore input grade.  The results were encouraging, and within the norm for this type of deposit.

The high non-magnetic silicates reflects the ferro silicates present in the host pyroxenite.  The range of 20-30% Fe Magnetic material is typical for this style of deposit.

Beneficiation Testing Results
Each of two composites was crushed to four (4) different sizes and subjected to a magnetic separation process as follows:

    6.3 mm (1/4")     Permroll Separator
    3.4 mm (6 mesh)     Permroll Separator
    1.7 mm (10 mesh)     Permroll Separator
    0.15 mm (100 mesh)     Sala Separator

The three permroll tests produced a concentrate, middlings and tailings product, while the Sala test resulted in a concentrate and tailings. All products were analysed for Fe3O4 (magnetite content). The composite samples were crushed and ground to 0.15 mm (100 mesh) and a significant upgrading occurred compared to 6.3mm to 1.7mm. At this 0.15mm size concentrate grades of 80.0% and 85.2% Fe3O4 were achieved.  These are very high and suitable for dry magnetic separation.  We may decide to ship iron concentrate at 100 mesh size to iron ore concentrators or alternatively put in our own pellitiser for easier bulk handling or depending on economics make sinter pellets.  A quotation has been received for both pieces of equipment, and a ball mill or tertiary crusher has been added to the plant configuration to accommodate these findings.
