TORONTO, ONTARIO--(Marketwire - June 16, 2011) - Inter-Rock Minerals Inc. (News - Market indicators) ("Inter-Rock") announces that its wholly-owned Colorado subsidiary, MIN-AD, Inc. ("MIN-AD"), has executed an asset purchase agreement (the "Agreement") with Unimin Corporation to acquire an operating dolomite quarry and plant located in Mill Creek, Oklahoma (the "Mill Creek Business"). 

MIN-AD currently supplies a high quality dolomite to the beef and dairy cattle feed industry. The acquisition of the Mill Creek Business will give Inter-Rock access to other specialty markets for dolomite. Additionally, there may be synergies with MIN-AD's business as Mill Creek is a favourable location to supply the beef industry. MIN-AD believes the Mill Creek dolomite is suitable for animal nutrition applications, but further research is required to verify this.

The purchase price for the Mill Creek Business is US$2 million to be paid in cash at closing, plus an adjustment post-closing in respect of inventory. Completion of the transaction is subject to customary closing conditions, including receipt of regulatory approvals. The acquisition will close on the date that is two business days following the satisfaction or waiver of the conditions set out in the Agreement. It is currently anticipated that closing will take place in approximately three weeks. Further information will be released to the market at the time of closing.
