Polar Star Mining Corporation-Los Azules Drilling Program

TORONTO, ONTARIO, Jan 15 (MARKET WIRE) --
Polar Star Mining Corporation (TSX VENTURE: POS)(PINK SHEETS: POSRF)
("Polar Star" or the "Company") is pleased to announce that a diamond
drilling program of an initial 2,500 metres commenced January 7, 2008 on
its 7,471 hectare Los Azules Property,Tierra Amarillo District, Region
III, Chile. Results being favourable, this program will immediately be
expanded to define a resource.

Highlights

- Six main copper, uranium and gold targets identified to date by Polar
Stars continuing geological and radiometric surveys

- Diamond drilling program underway on the 1,100 m long Araya main breccia

- Araya breccia is at the west end of a 1 km wide by 3-4 km long
alteration system hosting a number of breccia bodies

- SRK Consulting retained to provide independent supervision and quality
controle with a view to preparing NI 43-101 complient reports

Exploration History

There are no records of recent systematic exploration in the property
area; however, small scale mining has been carried out since at least the
1930's for oxidised copper ores in the 3% - 5% range. In Chile, the
average copper grade of similar breccias using bulk mining techniques is
typically in the 0.7 - 1.0% range.

Exploration by Polar Star

Current geological and radiometric surveys by Polar Star's personnel
using exploranium GS135 gamma ray spectrometers have outlined the Araya
breccia at surface over 1,100 metres by 90 metres and a production adit
intersects it at 85 metres vertical depth. These surveys indicated that
in fact this breccia is part of a much larger NE trending system of
alteration and breccia bodies up to 1km wide and 3-4 km long and have
also identified five additional breccia pipes on the property. All the
breccias identified contain oxidised copper minerals and are uraniferous.

Diamond Drilling Program

The initial diamond drill program will consist of a series of five fences
of three holes each spaced about 200 metres apart along the long axis of
the Araya breccia. This program is designed to investigate the three
dimentional shape and copper-uranium-gold grade distribution within the
upper oxidised section of the breccia. Results being favourable, this
program will immediately be expanded to define a resource.

Introduction

The Los Azules property, located 800 kilometers north of Santiago, covers
the historic Los Azules high grade oxide copper-gold mining district and
is readily accessible by paved and good gravel road from the city of
Copiapo sixty kilometers to the west.

Property Geology

The property is underlain by a generally sub-horizontal sequence of late
Cretaceous - Paleocene sub-areal epiclastic sediments and interbedded
andesitic flows, which are cut by numerous post-magmatic hydrothermal
collapse breccia pipes. The individual pipes, which are generally
elliptical in plan, have long axis ranging from 5 metres to 1,100 metres.
About 100 breccia pipes have previously been recognized in the Los Azules
District.

Mineralization

The hydrothermal mineralization of the pipes may be divided into an early
fragment replacement stage, followed by open-space filling. The filling
stage consists of tourmaline, accompanied by specularite and followed
principally by quartz, chalcopyrite, pyrite (+/- gold), molybdenite, and
galena. All the Azules pipes appear to contain uranium however, no
uranium minerals have been identified to-date. A zone of surface
oxidation up to 100 metres deep has produced a blanket of readily
leachable green secondary copper minerals, including atacamite,
chrysocola, brocanthite, copper wad and copper pitch.

NI 43-101 Report

Polar Star has retained the services of SRK Consulting's Santiago office
(see 27 November 2007 press release) to prepare a National Instrument
43-101 compliant report on the Los Azules breccia pipes project.

Qualified Person

The drill program will be carried out under the direction of Mr. Terence
Walker, M.Sc., P.Geo., qualified person within the meaning of National
Instrument 43-101. Mr. Walker has reviewed the contents of this news
release.
