Cliffs Natural Resources Inc. Reminds Spider Shareholders To Tender For Prompt Payment

Cliffs Does Not Anticipate Extending July 26, 2010 Expiry Date

CLEVELAND--(BUSINESS WIRE)-- Cliffs Natural Resources Inc. (NYSE: CLF) (Paris: CLF) today reminded shareholders of Spider Resources Inc. ("Spider") (TSXV: SPQ) that they have until July 26, 2010 at 11:59 p.m. (Eastern Time) to tender their Common Shares for Cdn.$0.19 under Cliffs' offer (the "Offer").

"Spider shareholders who want prompt payment should tender their shares now," said William C. Boor, President of Cliffs' Ferroalloys business unit. "Those who miss the deadline may have to wait up to several months to receive payment under a squeeze-out transaction, as Cliffs does not anticipate extending the offer again."

Cliffs already owns approximately 82% of Spider's Common Shares outstanding, calculated on a fully-diluted basis. If Cliffs obtains at least 90% of third-party shares through the tender process, it will be able to proceed with a compulsory acquisition. Otherwise, Cliffs intends to proceed with a squeeze-out transaction, for which it already has sufficient third-party shares. Cliffs expects that the squeeze-out transaction would occur late in the third quarter or early in the fourth quarter of 2010.

All Common Shares validly tendered by the extended expiry time will be taken up and paid for on July 26, 2010 under the Offer. The Offer price is a premium of 138% over the closing price of the Common Shares on the TSX Venture Exchange on May 21, 2010, the last trading day prior to Cliffs' announcement of its intention to bid for the Common Shares. The Offer implies a total equity value for Spider on a fully-diluted basis of Cdn.$125 million.

Notice of Extension

As previously disclosed, Cliffs filed under Spider's profile at a notice of extension dated July 16, 2010 in order to extend the expiry time of the Offer to 11:59 p.m. on July 26, 2010. As also previously disclosed, Cliffs filed at the original Offer and accompanying circular dated May 31, 2010, a notice of variation dated June 25, 2010, and a notice of extension dated July 6, 2010.

Spider shareholders, banks and brokers who have questions or requests for assistance regarding the Offer should contact Georgeson, Cliffs' information agent, toll free at 1-866-656-4120. Georgeson can also be contacted via email at
