Cliffs Natural Resources Inc. Increases Ownership of Spider To 81.8% And Extends Offer

Regulatory News:

Cliffs Natural Resources Inc. (NYSE: CLF) (Paris: CLF) announced today that it has taken up approximately 195.5 million common shares ("Common Shares”) of Spider Resources Inc. ("Spider”) (TSXV: SPQ) that were validly tendered as of July 16, 2010 at 11:59 p.m. (Eastern Time) under Cliffs’ offer (the "Offer”) to purchase all of the Common Shares. When combined with Cliffs’ prior holdings, Cliffs now owns approximately 81.8% of Spider on a fully diluted basis, up from 52.1% previously.

Cliffs has extended the time of expiry for the Offer to 11:59 p.m. (Eastern time) on July 26, 2010 in order to permit additional shares to be tendered. All Common Shares validly tendered by the extended expiry time will be taken up and paid for under the Offer. The Offer price is Cdn.$0.19 per share of Spider, 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.

"Now that Cliffs has over 80% of Spider’s shares, Cliffs has achieved its objective of gaining control over the Big Daddy chromite deposit,” said William C. Boor, President of Cliffs’ Ferroalloys business unit. "Even so, we have decided to give the remaining Spider shareholders a further opportunity to tender to our Offer in July, so that they don’t have to wait for several months to receive the same price under a compulsory acquisition or squeeze-out transaction.”

Spider has 659,262,891 Common Shares outstanding, calculated on a fully-diluted basis. The Offer implies a total equity value for Spider on a fully-diluted basis of Cdn.$125 million. Spider’s main asset is a 26.5% interest in the Big Daddy chromite project, which is located in the McFaulds Lake area of Northern Ontario. Cliffs now has effective control of 73.5% of Big Daddy, consisting of Cliffs’ directly held 47% interest and Spider’s 26.5% interest. Spider is scheduled to become project operator in April 2011.

Completion of Spider Takeover at Cdn.$0.19 per share

As stated in the Offer, Cliffs intends to complete the takeover of Spider by acquiring the rest of Spider’s shares. Cliffs expects the completion of the takeover to occur late in the third quarter or early in the fourth quarter of 2010, at which time the remaining Spider shareholders would be paid Cdn.$0.19 per share.

Under the Canada Business Corporations Act, Cliffs can complete the takeover by way of an amalgamation squeeze-out transaction, now that Cliffs has acquired more than two-thirds of the third-party shares of Spider. Alternatively, Cliffs can undertake compulsory acquisition procedures if Cliffs acquires 90% of the third party shares through the tender process.

Cliffs has filed under Spider’s profile at www.sedar.com 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 previously disclosed, Cliffs has also filed at www.sedar.com 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.
