Arrowstar Completes Benefication Testing from 105 samples, at Port Snettisham, Alaska, Iron Ore Project13:30 EST Tuesday, December 11, 2012 TSX.V: AWS VANCOUVER, Dec. 11, 2012 /PRNewswire/ - 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:                             Snettisham Samples % Chemical Analysis                 Fe   S   P   SiO2   Al2O3   TiO2   V2O5 K2O Na2O CaO MgO   Mn Ni Cu LOI Min   9.99   0.00   0.00   1.71   1.24   0.34   0.03 0.01 0.02 0.66 3.87     0.11   0.00   0.00   0.00 Max     58.35     0.41     2.10     44.06     10.15       6.53   0.57 1.77 1.77 20.65     32.30       0.40     0.05     0.03      10.73 Avg   21.28   0.03   0.41   32.46   5.20   2.55   0.18 0.39 0.27 12.96 13.52   0.18 0.01 0.01 1.33 Std Mev   9.24   0.08   0.53   7.72   1.99   1.28   0.11 0.43 0.27 5.76 7.21   0.06 0.01 0.01 2.59 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.

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.  Test: Sala 1 Sample: Beach Composite - 0.15 mm ( -100 mesh)         Product   Weight   Assay   % Yield     g    %   % Fe3O4   Fe3O4 Magnetic Product   37.0    37.8   80.0   83.2 Non Magnetic Tails   60.8    62.2   9.8   16.8 Calculated Head   97.7    100.0   36.4   100.0 Test: Sala 2 Sample: Pilings Composite -0.15 mm (-100 mesh) Product Weight Assay % Distribution   g                         %           % Fe3O4 Fe3O4 Magnetic Product 36.8 60.8 36.7     85.2 62.2 77.9 Non Magnetic Tails 63.5  60.8    63.3     14.0 62.2 22.1 Calculated Head       102.2             100.0 40.1 100.0 Phillip Thomas BSc Geol.
