September 11, 2012 – Arctic Star Exploration Corp. (TSXv:ADD) (the “Company” or “Arctic Star”) is pleased to report receiving the final data from the recently completed heli-borne geophysiscal survey on the El Havila property (the “Property”), located 32 kilometres ENE of Frontino, Colombia.
A 1237 line kilometer magnetic and radiometric survey was complete by a MPX Geophysics Ltd., utilising a helicopter, flown at 100m line spacing at a nominal 70m terrain clearance. The final data was received last week.
As reported earlier the company has identified a gold mineralised breccia zone that outcrops over 400m where it exposed in a creek and minor landslips. The actual size of the altered zone was not known as the outcrop disappears beneath soils and a mudstone veneer. The geophysical survey was conducted to determine the extent of the mineralisation and to aid in determining the prospectivity of the entire property.
The known mineralisation occurs in a 1350m by 500m magnetic low zone in the reduced to the pole total field magnetic data. This zone also coincides with an area with anomalous Potassium as determined by K channel radiometric data.
The most likely explanation for these geophysical signature is the epithermal alteration associated with the known outcropping mineralisation. The alteration is illite, sericite, silca dominated and this style of alteration causes the destruction/ conversion of magnetite in the host volcanics, causing the magnetic low. The alteration is also rich in potassium, explaining the radiometric anomaly.
The company now plans to conduct ground geophysics (IP, and Magnetics), and soil sampling over the now enlarged target area at El Havila. It is expected that this will be the final stage of work required prior to targeting drill holes on the property.
There are several other areas with similar geophysical signatures on the property which also need to be verified and investigated in the field.
The property lies within the prolific Cavca Gold Belt a highly prospective area with potential for porphyry related gold copper and epithermal precious metal deposits. The area is being explored by numerous companies including AngloGold Ashanti (La Colosa), Gran Colombia Gold (Marmato), and Continental Gold (Buritica).
