Arctic Star Diamond Corp.: Till Geochemistry Ugrades Multiple EM Targets, Strong Evidence for Widespread Nickel Mineralization,

Arctic Star Diamond Corp. ("Arctic" or the "Company") (TSX VENTURE:
ADD) is pleased to report on its ongoing work in expanding
Providence Lake nickel discovery, on its Credit Lake property NT.
To date, results have been returned for 689 till samples taken late
last summer (from a total of 1325). With these results,
approximately 50% of the samples have been received by the Company,
with the remainder (approximately 600 samples) of the results
expected in the next couple of weeks.
These till samples were taken along a 22km strike of the
Providence Lake Green Stone belt which hosts the magmatic,
komatiite-hosted nickel-copper-cobalt and platinum group element
(Ni-Cu-Co-PGE) sulphide discovery made by Arctic in 2008. The best
drill hole in the discovery area reported 5.1m @ 1.73%Ni, 1.75% Cu,
0.17% Co and greater than 2g/t platinum equivalent
(Pt+Pd+Rh+Ir+Os). The discovery drill hole was located on a
coincident EM (Electro-Magnetic) and high Nickel geochemical
anomaly (soil sample) and the company hopes to continue to use this
technique to target similar or better examples of this
mineralization along the belt.
Buddy Doyle VP Exploration for Arctic said, "These results are
exactly what we were hoping for from the till sampling program, the
results combined with VTEM collaborate the potential that the
original nickel sulphide discovery zone is not an isolated
occurrence and that there will be numerous other occurrences that
also have the potential to accumulate to a significant resource,
similar to other economic nickel camps around the world, such as
Raglan, Thompson and Kambalda. The proof will be in the drilling
which we are now eager to commence. We also await the till results
from the western side of the belt which we expect to be
similar."
The till sampling results that have been returned to date cover
the Providence Lake Nickel Discovery area (PLND) and a 4 kilometre
stretch of the Providence Greenstone belt. These initial results
are encouraging with eleven zones anomalous in nickel, cobalt,
copper, and chrome identified to date, each with similar soil
geochemistry to the anomaly associated with the PLND. (See Figure 1
below). The figure shows a gridded image of the nickel in till
results in colour. The "hot" colours, Purple, red, show the top 99
percentile of the nickel in till results with a maximum of 420ppm.
The warm orange yellow colours are the top 75 percentile results,
the blue represents all the samples below these cut-offs. The heavy
purple lines depict VTEM conductors thought to be associated with
nickel mineralization. Some of the other conductors in the VTEM
survey block have been field checked and shown to be caused by
sulphide facies iron formations. It is apparent from the figure
that the geochemical/geophysical expression of the PLND discovery
zone frequently reoccurs throughout the sampled portion of the belt
and often these signatures are an order of magnitude larger and
more intense than seen from the samples covering the PLND.

The company expects to commence exploration on this belt that is
west of the Tibbett-Contoyto winter road in March, and begin its
Spring drilling program in April.
