Cliffs Natural Resources Inc. Proposes Transactions to Acquire KWG Resources Inc. and/or Spider Resources Inc.

Acquisition of Either Company Would Meet Cliffs' Objective of Majority Ownership of "Big Daddy" Chromite Project

CLEVELAND--(BUSINESS WIRE)-- Cliffs Natural Resources Inc. (NYSE: CLF) (Paris: CLF) today announced that it intends to make take-over bids pursuant to which Cliffs or an affiliate would acquire all of the common shares of each of KWG Resources Inc. ("KWG") (TSXV: KWG) and/or Spider Resources Inc. ("Spider") (TSXV: SPQ) not owned by Cliffs or its affiliates.

Neither of the proposed take-over bids, which will be funded with Cliffs' existing cash resources, is conditional on the completion of the other.

Cliffs intends to offer to acquire KWG at a price of Cdn.$0.13 in cash per KWG common share. This represents a premium of 62.5% over the closing price of the common shares of KWG (the "KWG Shares") on the TSX-V on May 21, 2010. This offer price implies a total value for KWG of Cdn.$100 million. Directly or indirectly, Cliffs currently holds an aggregate of 111,733,215 KWG Shares and warrants to acquire 48,460,049 KWG Shares. This represents approximately 19.4% of the issued and outstanding KWG Shares on a fully-diluted basis.

Cliffs intends to offer to acquire Spider, also at a price of Cdn.$0.13 in cash per Spider common share, before giving effect to any share consolidation. This represents an identical 62.5% premium over the closing price of the common shares of Spider (the "Spider Shares") on the TSX-V on May 21, 2010. The offer price implies a total value for Spider of Cdn.$86 million. Cliffs holds an aggregate of 19,642,500 Spider Shares representing approximately 3% of the issued and outstanding Spider Shares on a fully-diluted basis.

On May 21, 2010 and May 23, 2010, Cliffs proposed a transaction to the board of directors of each of KWG and Spider, respectively, to acquire all of the outstanding common shares of KWG and Spider not owned by Cliffs or its affiliates at the offer prices mentioned above. Each proposal contained a "go shop" clause providing KWG and Spider with the opportunity to proactively canvass the market for a third party offer at a price superior to that proposed to each by Cliffs. However, neither KWG nor Spider agreed to the transaction terms proposed by Cliffs within the timeframe that Cliffs had established.

Cliffs currently owns a 47% interest in the "Big Daddy" chromite project located in the McFaulds Lake area of Northern Ontario. KWG and Spider each own 26.5% of Big Daddy and have the option to earn-in up to 30% each. Cliffs' objective, which can be achieved by acquiring either KWG or Spider, is to obtain majority ownership of Big Daddy.

William C. Boor, president of Cliffs' Ferroalloys business unit, said, "While we intend to provide each company's shareholders the opportunity to receive a significant cash premium, we only need to acquire either KWG or Spider in order to satisfy our strategic objectives with respect to the Big Daddy deposit. It would be a satisfactory outcome for Cliffs if either proposed acquisition were successful, leaving Cliffs as majority owner and operator of Big Daddy with one junior partner. Preliminary estimates indicate that our wholly-owned Black Thor deposit is larger and wider, making it more amenable to open pit operations than Big Daddy, so our current plan is to develop Black Thor and our other wholly-owned Black Label chromite deposit first. However, obtaining control of Big Daddy would enable Cliffs to develop the most appropriate integrated long-term mine plan for moving this new mining district forward."

Cliffs believes that its proposals, which in aggregate imply an equity value for these two companies, on a fully diluted basis, of Cdn.$186 million, should be highly attractive to KWG and Spider. Neither KWG nor Spider has significant assets other than their combined 53% interest in Big Daddy. By comparison, earlier this year Cliffs acquired Freewest Resources Canada Inc. for approximately Cdn.$240 million. Freewest's assets were indisputably superior to the combined holdings of KWG and Spider, as in addition to its 47% interest in Big Daddy, Freewest owned 100% of the Black Thor and Black Label properties, certain non-core gold assets, common shares of Quest Uranium with a market value of Cdn.$13 million at closing and Cdn.$8.0 million in cash.

Transaction Details

A formal offer has not yet been made to shareholders of KWG or Spider. In the case of the proposed offer for the KWG Shares, Cliffs is a KWG insider, so it has formally requested that the board of directors of KWG, through an independent committee, selects a valuator and directs it to prepare as soon as practicable a formal valuation of the KWG Shares as required by applicable securities laws prior to Cliffs or an affiliate making a formal offer for the KWG Shares. No such valuation is required in respect of the Spider Shares.

In connection with Cliffs' proposal, Richard Fink, Cliffs' vice president, technical business development, resigned from the KWG board of directors, effective May 21, 2010.

Cliffs intends to mail a take-over bid circular, including its offer to purchase and other related materials, to Spider shareholders as soon as practicable, and to KWG shareholders conditional upon receipt and review of the requested valuation.

Both take-over bids are expected to have substantially similar conditions, including a condition that there shall have been validly deposited under the bid and not withdrawn at the time of expiry of the bid such number of common shares of the issuer that, together with such common shares held by Cliffs and its affiliates, constitutes at least 66 2/3% of the common shares then outstanding (calculated on a fully-diluted basis). In each case, if the conditions of the bid, including such minimum tender condition, have not been satisfied at the time of expiry of the bid, Cliffs will not be subject to any obligation to acquire any shares tendered to the bid, or to waive any conditions of the bid or extend the bid.

Cliffs has retained BMO Capital Markets as its exclusive financial adviser and Blake, Cassels & Graydon LLP as its legal adviser.
