All 2009 Till Results for Credit Lake Received

Compelling Geochemical Responses Cause Geophysical

Targets to be Upgraded to Very High Priority Drill Targets for April, 2010 Program

Arctic Star Diamond Corp. (“Arctic” or the “Company”) is pleased to report that it received all of the 2009

till geochemical results at Credit Lake. This program was designed to, and succeeded in, discovering new

targets that may be due to blind (buried) mineralization along the strike of the Providence Greenstone

Belt. This belt contains the magmatic, komatiite

hosted nickelcopper

cobalt and platinum group element

(Ni

CuCo

PGE) sulphide discovery made by Arctic in 2008 which was also selected on the basis of an EM

(Electro

Magnetic) target that was coincident with a high nickelin

soil geochemical anomaly. Arctic’s best

drill hole in the discovery area reported 5.1m @ 1.73%Ni, 1.75% Cu, 0.17% Co and >2g/t platinum

equivalent (Pt+Pd+Rh+Ir+Os).

The final compilation of these geochemical data clearly indicates, enhances and defines eight high priority

nickel+copper+cobalt targets in the Central and Western Zones in addition to the eleven targets identified

in the Eastern Zone, which were discussed in our new release of February 8, 2010. Most of the eight

priority zones coincide well with geophysical targets that were developed from the 2008 VTEM airborne

survey. Numerous of these soil anomalies possess signatures of magnitudes equal to or greater than that

signature developed from detailed soil sampling over the discovery area.

Figure 1 (below) illustrates the soil targets by overlaying three datasets.

The grey scale image in the background is a gradient map of the total magnetic field. The arcing east

west

trending bands map the ultramafic rock types that host the nickel mineralization at the 2008 discovery

site. The north

northwest striking features are young diabase dykes that intruded the Providence Belt

much later than the mineralizing events.

The VTEM response (channel 23) is shown in color: The "hotter" the color, the “stronger” the

electromagnetic response. Anywhere that the VTEM response and the magnetic response coincide, is

considered an excellent drill target. There are 45 separate areas and zones where this occurs.

The nickel, plus copper, plus cobalt geochemical response from the till sampling for which the results are

being reported here are superimposed on the image as 50ppm contours. The more anomalous areas are

represented by dense compact lines on the image. Red arrows have been placed where there is a strong

correlation between the geochem and a nickel EM signature; the yellow arrows represent areas where

ground EM investigation is warranted.

Buddy Doyle VP Exploration for Arctic said, “These new results continue to reinforce the notion that both

this type of sampling method is effective in the Arctic and that the Providence Belt has potential for

additional new discoveries. The proof will be in the drilling and I am pleased to say that we are beginning

mobilization for the spring, 2010 program by ordering the fuel needed to be hauled up the winter road.

We expect drilling to begin on or about April 1st.”

Table 1 summarizes some of the characteristics of the VTEM targets where they coincide with till

geochem anomalies in the Central and Western Zones.
