Release date- 20122013 – Scottsdale, Arizona – International Minerals Corporation and Chaparral Gold Corp. announce the closing of the previously-announced transaction by way of a plan of arrangement involving IMZ and Hochschild Mining plc, pursuant to which Hochschild has acquired all of the outstanding shares of IMZ.

Under the terms of the Arrangement, each IMZ shareholder (other than Hochschild in respect of the cash) is entitled to receive cash consideration of US$2.38 per IMZ share and that number of common shares in Chaparral Gold as is equal to their shareholdings in IMZ.

Immediately prior to closing, the following non-Peruvian assets and related liabilities previously held by IMZ were transferred to Chaparral Gold:

IMZ’s cash and receivables (estimated at approximately US$58 million) and

IMZ’s non-Peruvian subsidiaries and their assets and related liabilities, including the Goldfield and Converse gold properties in Nevada.

Chaparral Gold common shares have been conditionally approved for listing on the Toronto Stock Exchange (‘TSX’, symbol CHL), subject to satisfaction of customary listing conditions, and it is anticipated that the initial trading date will be December 30, 2013.

IMZ’s shares are now owned by Hochschild and will cease to be traded on the TSX, the SIX Swiss Exchange (the ‘SIX’) and the Open Market (Regulated Unofficial Market) of the FWB Frankfurter Wertpapierborse (the Frankfurt Stock Exchange) and various other stock exchanges in Germany, in accordance with the rules of each exchange. Formal delisting from the TSX and the SIX will take place before the end of the year.

Former IMZ President/CEO, Stephen Kay, commented: ‘IMZ is pleased to have concluded this complex transaction with Hochschild and wishes both Hochschild and Chaparral Gold much success in the future.’ Mr Kay will assume the role of Executive Chairman of Chaparral Gold.

Chaparral Gold CEO, Nick Appleyard, commented: ‘Chaparral Gold is being launched with 100% ownership of two high-quality gold properties in Nevada, one of the most favorable mining jurisdictions in the world. In addition, with approximately US$58 million in cash and receivables, it is well capitalized to advance the Nevada properties as considered appropriate in the current market conditions and, importantly, to seek new opportunities in the mining sector.’
