VANCOUVER, British Columbia – Polaris Minerals Corporation (TSX:PLS) confirms that its subsidiary company, Eagle Rock Aggregates Inc., has received a Building Permit for the construction of its aggregates receiving, storage and distribution terminal in the City of Richmond, San Francisco Bay. The construction costs of the redesigned facility are now estimated to be US$27.4 million, a reduction of US$9.1 million, or 24.9%, from previous estimates.

Negotiations are now well advanced with the two principal contractors, Hayward Baker Inc. for the ground remediation and foundation works, and Terra Nova Technologies, Inc. for the mechanical, building and electrical installations. Both contractors are well-recognized in their respective fields, with considerable experience in the State of California. The projected cost includes US$0.5 million expended since January 2006 for professional fees arising from the redesign of the facility and preparing the building permit application, and also includes allowances for dredging of the ship berth and the purchase of mobile equipment. It is anticipated that work will commence on site by the end of September 2006 and that the construction period will be nine months. Financing for the construction will be provided from the Company’s US$31 million debt facility, the first draw down from which is expected to take place in September.

Marco Romero, the Company’s President and Chief Executive Officer, commented: “We are pleased to be achieving these significant capital cost savings through the extensive redesign which will only delay the anticipated start-up date by about three months. Meanwhile, other third party market opportunities are advancing, which we believe will allow our 2007 sales forecasts to be achieved. The Richmond facility represents a rare opportunity to develop a long term strategic gateway into the important San Francisco Bay market.”

Polaris Minerals Corporation is exclusively focused on the development of quarries and the production of construction aggregates in British Columbia for marine transportation to urban markets on the west coast of North America to meet growing local supply deficits.
