On January 16, 2013, Arrowstar announced that it has staked an additional 21 claims adjacent to and continuous with its Port Snettisham, Alaska iron ore claim block (49 claims). The additional 21 claims adjoin the present claim block to the east and south in an area potentially extending an area of magnetic highs indicated during the Company's geophysical surveys conducted this past summer. The new claim block expands the Company's project area by about 43%.
SNETTISHAM IRON ORE - A BRIEF HISTORY
Picture of the tenement from North to South. The second inlet (where the old pier is) is where gold mining was conducted in 1908.
The beach area to the south of the tenement, where magnetite bearing pyroxene outcrop forms a black band at the forest level.
The magnetite bearing pyroxene mineralisation is highly magnetic and extends for 2000m along the foreshore.
In parts of the outcrop, large boulders of aplite (white mineral - feldspar and quartz) appears with crystalline magnetite and apatite (green mineral - found often with magnetite (eg. Kiruna)
To the north the diorite host rock contacts with a metamorphosed phyllite, and the magnetic field from the magnetite stops.

The forest is reasonably dense close to the shoreline, but thins out further as you ascend to 1500 feet above sea level.
