Nevoro to Acquire Sheffield Resources Ltd.

TORONTO, ONTARIO--(Marketwire - June 10, 2008) - Nevoro Inc. ("Nevoro") (TSX:NVR) is pleased to announce that it has entered into a definitive agreement (the "Arrangement Agreement") to acquire all of the issued and outstanding securities of Sheffield Resources Ltd. (TSX VENTURE:SLD) ("Sheffield"), pursuant to an engagement agreement previously announced in Nevoro's press release dated April 24, 2008 (the "Arrangement").

Nevoro and Sheffield plan to complete the Arrangement by way of a court approved plan of arrangement pursuant to S.288 of the Business Corporations Act (British Columbia) whereby each issued and outstanding Sheffield common share will be cancelled and the holder thereof will receive 0.80 of one Nevoro common share. Currently, Sheffield has 35,422,497 common shares issued and outstanding. Holders of Sheffield's common share purchase warrants ("Sheffield Warrants"), in accordance with the terms of such warrants, in lieu of Sheffield's shares, shall receive upon the subsequent exercise of such holder's Sheffield Warrant, 0.80 of one Nevoro common share. Each holder of an outstanding Sheffield stock option shall receive such number of Nevoro options, to acquire one Nevoro common share, equal to the product of: (i) the number of Sheffield options held immediately before the closing of the Arrangement, and (ii) 0.80. The exercise price per Nevoro share shall be an amount equal to the quotient of (A) the exercise price per Nevoro Share subject to such Sheffield option immediately before closing divided by (B) 0.80.

Currently, Nevoro has 75,163,585 common shares outstanding. Nevoro announced on April 17, 2008 a proposed plan of arrangement to acquire 100% of Aurora Platinum Exploration Inc. (formerly Aurora Metals (BVI) Limited) ("Aurora") (OTCBB:AURMF), the terms of which provide for the issuance of 19,981,476 shares. Upon the closing of the Aurora acquisition and the Sheffield acquisition, both as currently proposed, Nevoro will have approximately 123,483,058 issued and outstanding common shares, at which point Nevoro's current shareholders will hold approximately 60.9%, Sheffield shareholders will hold approximately 22.9% of these shares, and Aurora shareholders will hold approximately 16.2% of Nevoro's outstanding shares.

The acquisition of Sheffield is subject to all requisite regulatory approvals, court approval, obtaining all security holder approvals required by applicable laws and such other conditions as are customary in transactions of this nature. Sheffield will be seeking shareholder approval of the proposed acquisition, in a meeting to be held on or about July 25, 2008.

As part of the Arrangement Nevoro has agreed to provide working capital funding to Sheffield by way of a secured grid promissory note (the "Grid Note") under which Sheffield can request advances up to C$400,000, in the aggregate, from Nevoro. The advances will be secured by a mortgage of Sheffield's interest in the Moonlight Copper Project in Plumas County, California and are subject to an interest rate equal to the Prime Rate, as quoted by the Royal Bank of Canada, plus 2% per annum. The Grid Note can be called on 90 days notice by Nevoro and can be satisfied, at Sheffield's option, by repaying it or by the issuance of common shares based on a conversion rate equal to the lower of: (i) 75% of the average closing price of Sheffield's common shares as listed on the Toronto Stock Exchange - Venture Exchange (the "TSX-V") for the 20 trading days immediately preceding the date of this Agreement; and (ii) 75% of the average closing price of Sheffield's common shares as listed on the TSX-V for the 20 trading days immediately preceding the effective date of conversion (being the 90th day after the date of demand), and subject to the acceptance of the TSX-V to these terms of conversion.

Sheffield's principal asset is the Moonlight Copper project located 140 km northwest of Reno, Nevada in Plumas County, California. The Moonlight Copper project is a 6,857 acre porphyry-Cu and Cu-oxide property with current NI 43-101 compliant indicated resources of 161.57 million tons averaging 0.324% Cu (at 0.2% Cu cutoff), 0.003 oz./ton Au and 0.099 oz./ton Ag, plus inferred resources of 88.35 million tons averaging 0.282% Cu, 0.003 oz./ton Au and 0.089 oz./ton Ag.

Additionally, Sheffield has an option to enter into a joint venture agreement, or to acquire the 9,161-acre, early-stage, Golden Loon Ni-Co-PGE-Au property, 80 km north of Kamloops, British Columbia. Historical exploration including limited drilling, geochemistry and geophysics has identified encouraging Ni-Co and PGE mineralization in ultramafic rocks that underlie the property (Sheffield news release, March 6, 2007).
