Polar Star Applies for Extension of NI 43-101 Technical Report Filing TORONTO, May 21, 2009 /CNW/ - Polar Star Mining Corporation ("Polar Star" or the "Company") announced it has applied to the Ontario Securities Commission for an extension of the filing of its National Instrument 43-101 technical report (the "Report") on the Chépica Project. The Company, together with SRK Consulting, has refined the geostatistical parameters of the resource model, which may impact the grade and tonnes first previously reported on April 8, 2009. "We instituted a disciplined procedure to examine the draft SRK Consulting Report and all agreed we needed more time to complete the process," said Doug Willock, President and CEO of Polar Star.
The extension relates to a draft of the Report, which the Company received on April 7, 2009 and reported on April 8, 2009. The Report was received and the press release was issued prior to the election of the new board of the Company on April 20, 2009. Investors should not rely on the information in the previous draft report and mineral resource estimate until the final Report is filed.
The Company will issue a news release when the final Report is filed on SEDAR which is expected to occur on or before June 23, 2009.
Qualified Person
The qualified person within the meaning of National Instrument 43-101 is Mr. Terence Walker, M.Sc., P.Geo. Mr. Walker has reviewed the contents of this news release.
