Polar Star Provides Shareholders With Facts in Information Update Warns Against Misleading Dissident Statements

NOT FOR DISTRIBUTION TO UNITED STATES WIRE SERVICES OR DISSEMINATION IN THE
UNITED STATES


Polar Star Mining Corporation (TSX VENTURE:PSR) ("Polar Star" or the "Company")
today issued a letter providing updated information for shareholders to consider
in voting their YELLOW proxy in time to be counted at the Company's annual
meeting on April 17, 2009 in Toronto.


The letter notes the recommendation from proxy advisory firm RiskMetrics Group
that Polar Star shareholders vote in favour of the management nominees at the
annual meeting. It shows the startling disparity between dissident shareholder
Douglas Willock's promises about the Company's Chepica project and actual
resource estimates. It also warns shareholders against accepting misleading
statements from Mr. Willock and his associates.


The full text of the letter from Executive Chairman Stephen G. Roman, on behalf
of the management nominees to the Board of Directors, follows:


April 8, 2009

Dear Fellow Shareholders,

- Polar Star needs your support to pursue prospective targets and build value -
Vote only your YELLOW proxy


- Industry leading proxy advisory firm recommends support for Management nominees

- Independent report of Chepica resource estimates validates your Board's
prudent approach


- Dissident continues to mislead shareholders

Within the next few days, as shareholders of Polar Star Mining Corporation, you
will make a crucial decision about the direction of your Company. I believe you
will base your choice of a Board of Directors on facts and your own best
interests. Therefore, I am asking you to vote your YELLOW proxy in favour of the
management nominee slate of directors by 10:00am ET on April 15, 2009, to ensure
your vote can be counted at the Company's annual meeting on April 17.


On behalf of the management nominees, I am providing you with this update and
asking for your support to build a more valuable Polar Star.


As you know by now, your Board believes that the dissident shareholder Douglas
Willock is seeking to fill the Board of Directors with his own hand-picked
nominees in order to take effective control of the Company and lead it towards
potential disaster. We believe his nominees would not act independently to
prevent his ill-considered "vision". Unlike the management nominees for the
Board, Mr. Willock's slate lacks the relevant skills and experience to guide
your Company to enhanced value for all shareholders.


Consider these recent important developments as you make your decision and cast
your vote:


1. Independent Endorsement of the Management Nominees: RiskMetrics Group, a
leading proxy advisory firm relied upon by institutional shareholders, has
recommended that Polar Star shareholders vote to support the
management-nominated Board slate. RiskMetrics met with both sides and reviewed
the facts. It noted: "The management nominees are highly experienced, have
successful track records and appear better able to create shareholder value.
Therefore support is warranted for the management nominees." It also said: "No
major strategic missteps or significant abuse of shareholders' rights are
apparent in the Board's actions. The Board's strategy appears reasonable and
prudent in the circumstances."(i)


2. Chepica Project Report: Polar Star yesterday announced resource and grade
estimates for the Chepica Project in southern Chile. The draft NI 43-101 report
submitted by SRK Consulting (Chile) supported the prudent approach of management
and your Board. The report included the following findings that were not
unexpected by your Board - but are in stark contrast to Mr. Willock's "vision":


Mr. Willock previously stated to the Board and investors that the mill head
grades would be 1.5 per cent copper and 6 grams gold per tonne and that Chepica
would "generate significant cash flow and fund operations and exploration of
Polar Star's other properties". In fact, the SRK report indicates the resource
grade is only 0.48 per cent copper and 2.6 grams gold per tonne with only a
400,000- tonne Measured and Indicated Resource at these grades. This is totally
insufficient to validate any mining scenario at Chepica.


An independent review by renowned geologist Dr. William Roscoe of Scott Wilson
Roscoe Postle Associates stated that "the head grades appeared to be decreasing
with depth." In addition, further independent test results from the University
of La Serena show disappointingly low gold and copper recoveries of
approximately 65% each, with the quality of concentrate not meeting minimum
requirements for sale to ENAMI, the state-run smelter for small mining
operations.


These findings prove that Chepica would be a catastrophic cash drain, not a cash
generator for Polar Star. Mr. Willock`s naive expectations and inexperience led
him to promote what he believed was there. He continues to propose further
spending at Chepica. Despite Mr. Willock's demands, your Board insisted on a
proper technical review before committing to further significant cash outlays of
valuable shareholder funds. The NI 43-101 report confirms your Board's view that
Chepica is not a material property to the Company. Nevertheless, the technical
report will be filed by the Company, to provide shareholders with the
information currently available to the Board.


3. Misleading dissident statements: Shareholders have advised us that Mr.
Willock and his proxy solicitor continue their high-pressure calling campaign,
making questionable statements about Mr. Willock's current shareholder support
levels, the mining qualifications of his nominees, and corporate governance
practices at Polar Star. As recently as today, Mr. Willock issued a press
release saying "it is difficult to understand RiskMetrics support" of the
management-nominated slate, and purporting that, at time of his termination, he
had "majority support" from a few shareholders. The explanation is simple: this
world-leading governance advisory firm had benefit of all the facts, not just
Mr. Willock's self-serving representations to select shareholders. All
shareholders are now seeing the whole picture.


Shareholders are advised to ignore the dissident claims and get the facts from
the Management Information Circular previously issued, and updates available at
the Company website www.polarstarmining.com. We urge you to focus on the facts,
consider the strategy, experience and track record of the Management Nominees,
and vote your YELLOW proxy now.


Polar Star is now on the right track and focused on high-potential projects. Mr.
Willock's reckless spending has been stopped. Your Company has brought together
an excellent, highly independent, Board and an experienced management team --
people who know the industry, have a proven track record of success, and an
ambitious yet realistic plan for growth.


It is unfortunate that the Company and the shareholders have been subjected to
this time-consuming, costly and unwarranted action by Mr. Willock. It is
important that you cast your vote now. If you have not already voted or you have
voted a blue proxy, please vote your YELLOW proxy now in support of management.
Your latest dated proxy received before proxy cut-off overturns any previous
ones. With your support, on Friday, April 17th, a new chapter will begin for
Polar Star and we will strive to repay your confidence with results.


Thank you for your continued support and trust in our experience.
