For Immediate Release


Arrowstar Exploration Program on Roberts Lake, Quebec Identifies Three Large Outcrops showing Iron Ore Mineralization

Highlights:

Three large magnetite outcrops, the largest measuring 500 metres by 600metres were identified in the west of the 128 c
--->laims located about 40km northwest of  Kangirsuk and 1,647 kilometres north of Montreal, Quebec.
25 samples were taken and values  were recorded on the "Magnetite" Scale of a KT-10 Plus magnetitic susceptibility met
--->er.
The samples will be assayed and a ground based magnetic survey planned as follow up.
 
Vancouver, B.C. - July 27, 2012, Robert L. Card, President of Arrowstar Resources Ltd., ("Arrowstar" or the "Company")
---> (TSXV: AWS), is pleased to report that Phillip Thomas, Vice -President Exploration and Director visited the property 
--->on 14 June 2012 and was able to locate three large outcrops of shallow dipping granodiorites, and carbonates containin
--->g magnetite and hematite. The chert-magnetite-hematite iron formation contains specularite an altered magnetite minera
--->l.

Significant outcrop and float is exposed on the surface with no trees and very little overburden.  There are numerous 
--->small lakes in the area.

The general stratigraphic sequence observed is composed of an Archean age granite gneiss basement; unconformably overl
--->ying the granite gneiss is a succession of meta-sedimentary rocks. Immediately overlying the granite gneiss in some ar
--->eas is quartzite of the Ford Lake Formation. The quartzite contains surface expressions of magnetite and lenses or pod
--->s of mica schist. The quartzite grades upward into the Sokoman Iron Formation. The iron formation may be further subdi
--->vided based on variations in magnetite, hematite, carbonate and iron silicates. A conspicuous spotted iron silicate-ca
--->rbonate-quartz bed that caps the iron formation was identified at site two. Micaceous schist and slate that are intrud
--->ed by gabbro sills overlie the Sokoman iron formation. This was identified as outcrop and float predominately in outcr
--->op three.
Strong folding has resulted in a structural influence on the iron formation. Thrusting and recumbent folding of the ir
--->on formation in several areas has led to limb thickening, thinning, and doubling up of the mineralized horizons in som
--->e locations. The known deposits or more prospective areas on the property are those areas where the iron formation has
---> been deformed and is now flat-lying, or slightly dipping with a strike to the NNE and dipping about 15 degrees, and r
--->aised above the surrounding non-mineralized rocks, deformed into anticlines or synclines, doubled up or otherwise thic
--->kened.
Concentrating ores are typically composed of magnetite and or hematite and silicate minerals at relatively low grades 
--->(20-30% Fe) that require grinding to liberate magnetite and/or hematite from the silicate minerals. Magnetite is conce
--->ntrated by magnetic methods and hematite is concentrated by gravity or flotation methods.
The value of concentrating ores is determined by a combination of Fe grade and ease of liberation. For example, a lowe
--->r Fe grade ore may have a higher value than a higher Fe grade ore if it liberates at a coarser grind enabling greater 
--->throughput with lower grinding costs.   
Samples have been sent for assay and will be reported when available.
