Vancouver, British Columbia - Polaris Minerals Corporation (TSX: PLS) ("Polaris" or the "Company") announced today that it has filed with Canadian securities regulatory authorities an updated National Instrument 43-101 Technical Report (the "Technical Report") on Polaris' Orca Sand and Gravel Quarry, prepared by AMEC, who also prepared the earlier October 2005 Technical Report and Feasibility Study (the "2005 Report"). The Technical Report updates future expectations for pricing, volumes, costs, cash flows, capital requirements and supply and demand in Polaris' target markets. All figures are in US$ unless otherwise noted.

The Technical Report includes the following updated projections:

• Increased sales volumes are expected to reach 9.6 million tons per year by 2015 (Project Case) through 24/7 operations, without requiring significant additional capital expenditure at the quarry. The customer relationships the Company has added since the 2005 Report and the purchase of the Long Beach terminal site are key elements of this ramp up from the previous 6 million tons projected.
• Increased NPV by an expected 74% over the 2005 Report level to $226.7 million at a 10% discount rate (Project Case) despite more modest volume and pricing assumptions in 2009 and 2010, which reflect the current economic slowdown.
• No significant capital investment required for new terminal construction in California until 2011.
• Price of sand and gravel is expected to continue to increase, in real terms, beginning in 2011 due to supply shortages and the difficulty of replacing assets in the target markets. The assumptions are more modest than in the 2005 Report, and may offer additional future upside potential.
• Positive operating cash flow is expected to be generated (before tax) annually throughout the productive life of the quarry.

Herb Wilson, Polaris' Chief Operating Officer, commented: "This independent technical report has been updated using the most current projections available, and clearly demonstrates the strong cash generation potential of the Orca Quarry. The report has incorporated the unforeseen and unprecedented reductions in demand for construction aggregates experienced in 2007 and 2008. However, our goal now is to increase sales to 9.6 million tons per year by 2015, a level we expect to achieve based on the excellent operational performance by our quarry operators to date, the projected supply/demand imbalances in our target markets and the volume capacity of our current and planned terminals. We will need to amend our mine permit to accommodate this increase over the current permitted production level, and expect that we will be able to do this in a straightforward manner when the time comes." He added: "the quarry requires only minimal additional capital to achieve this target and our next significant port development costs are not anticipated to be until 2011".

	Net Cash flow after tax (000,000's)	$35.7	$62.4	$31.3	$54.5
Life of mine production cost ($/ton)		$2.18	$2.55	$2.18	$2.55
NPV (10 percent discount) (000,000's)		$130.6	$226.7	$107.7	$208.9
Payback period (years)		5.7	6.6	5.6	6.4
IRR		21.8%	22.1%	23.8%	22.8%

Note: The financial assumptions in the Technical Report are presented in two formats: Project Case and Beneficial Case. The Project Case includes 100% of the assets and operations of Orca, including the aggregates receiving terminals in Richmond and other southern California locations, and assumes that all capital expenditures for the project will be funded by equity and does not take into account any debt financing that may be required. The Beneficial Case recognizes the beneficial interests of the Company in the Project (88%) and the aggregates receiving terminals (70%), and assumes that the future capital requirements are funded by a combination of debt and equity. The Beneficial Case also includes assumptions regarding financing arrangements of the Company's First Nation partners for their portions of the development costs of the Orca Quarry and the Richmond Terminal. Neither case includes Polaris head office costs in its assumptions. The Payback period for the 2005 Reports is from 2007 and the Payback period for the 2008 Reports is from 2009. For further details on the assumptions please see the Technical Report.

Extending the quarry life past 2025
The Technical Report assumes the Orca Quarry will reach a peak annual sales volume of 9.6 million short tons per year by 2015, a level expected to be maintained until 2025, when the East Cluxewe reserves are exhausted. The current level of proven and probable reserves at the East Cluxewe deposit remains unchanged from the 2005 Report at 134 million tons (less material mined to August 25, 2008 of 3.23 million tons). The Company is awaiting the results of its 2008 exploration program, which had the stated objective of identifying additional resources in the area surrounding the Orca Quarry that could potentially be used to extend the life of the operation past 2025. The results of the exploration program are expected in the first half of 2009.
