Teck Cominco President and Chief Executive Officer, Donald R. Lindsay said: “The acquisition of Aur Resources will immediately increase our cash flow and add substantially to our long term growth in copper production. We are pleased to re-establish our operating presence in Chile and believe that this transaction will create significant value for Teck Cominco shareholders.”

“The cash and share offer of $41 per Aur share made by Teck Cominco is an excellent offer which has been unanimously supported by an independent committee of and by our entire board of directors. The offer represents a substantial premium to Aur’s share price, with the share component providing our shareholders the opportunity to participate in the future growth prospects of Teck Cominco on a tax deferred basis” said Dr. Gill, President and Chief Executive Officer of Aur. “I cannot think of a buyer better suited to managing Aur’s assets going forward and I look forward to being a Teck Cominco shareholder for many years”.

The acquisition of Aur Resources will enhance Teck Cominco’s copper production and reserves:

• Annual copper production will grow immediately by over 200 million pounds – an approximate 43% increase;

• Annual copper production by 2010 is expected to increase by 342 million pounds, or 72% over 2007 pre-transaction level;

• Copper reserves and resources will increase by 15 billion pounds or 136%, of which 8 billion pounds are in reserves

Dr. Norman B. Keevil, Teck Cominco’s Chairman, said: “This transaction is consistent with Teck’s continuing strategy of balance in building the company. It will add both current copper production and new copper operations under development, and the increase in our copper interests will help to balance our existing strength in zinc and coal”

Teck Cominco will finance the cash portion of the offer using its substantial cash resources. With the payment of today’s dividend, Teck Cominco has returned more than $1 billion to shareholders in 2007, through dividends and the repurchase of 13.1 million Class B shares for $577 million pursuant to a normal course issuer bid.

Mr. Lindsay said: “Our offer presents an attractive opportunity for Aur’s shareholders. They will receive a significant premium over the historical highest price for their shares while also benefiting from the opportunity to participate in a larger, broadly diversified company with a strong balance sheet, enhanced dividend yield and long term growth potential.”

Teck Cominco and Aur have entered into a support agreement which provides for, among other things, a non-solicitation covenant on the part of Aur, subject to customary “fiduciary out” provisions that entitle Aur to consider and accept a superior proposal, a right in favour of Teck Cominco to match any superior proposal and the payment to Teck Cominco of a termination payment of C$140 million if the acquisition is not completed as a result of the superior proposal.

The Board of Directors of Aur, after consultation with its financial and legal advisors, has unanimously approved entering into the support agreement and recommends that Aur shareholders tender to Teck Cominco’s offer. CIBC World Markets Inc., acting as financial advisor to Aur, has provided an opinion that such offer is fair, from a financial point of view, to Aur shareholders. Aur’s legal advisors are Heenan Blaikie LLP.

Full details of the offer will be included in a formal offer and takeover bid circular to be mailed to Aur shareholders in accordance with applicable securities laws. Teck Cominco expects to mail the takeover bid documents to Aur shareholders on or before July 18. The offer will be open for acceptance for at least 35 days following the date of the mailing. The offer will be subject to the usual conditions including receipt of all necessary regulatory approvals, absence of material adverse changes and acceptance of the offer by Aur shareholders owning not less than 66?% of the Aur shares on a fully diluted basis. Once the 66?% acceptance level is met, Teck Cominco intends to take steps to acquire all the outstanding Aur shares. Teck Cominco intends to promptly make the necessary regulatory filings in respect of the offer with the appropriate authorities. Teck Cominco expects the offer to receive regulatory approval in the normal course. Teck Cominco’s financial advisors are Merrill Lynch Canada Inc.
