International Minerals Announces Closing of Sale of Ruby Hill Royalty

SCOTTSDALE, AZ--(Marketwire - May 23, 2012) - International Minerals Corporation (TSX: IMZ) (SWISS: IMZ) (or "the Company") is pleased to announce the closing of the previously-announced (see news release dated May 15, 2012) sale of its 3% net smelter return (NSR) royalty on production from Barrick Gold Corporation's Ruby Hill gold mine in Nevada (the "Ruby Hill Royalty") to Royal Gold, Inc. ("Royal Gold"), a major international royalty company, for cash proceeds of $38 million.

The Company acquired the Ruby Hill Royalty as part of its acquisition of Metallic Ventures Gold, Inc. ("Metallic") in February 2010 for approximately $60 million in a combination of cash and IMZ shares. In addition to the $38 million proceeds from the sale of the royalty to Royal Gold, the Company has also received an additional approximately $9.5 million in aggregate royalty payments from the Ruby Hill Mine since the Metallic acquisition.

As part of the Metallic acquisition in 2010, the Company also acquired the Goldfield and Converse advanced exploration gold properties, both in Nevada. These properties currently host gold deposits with combined measured and indicated ("M&I") mineral resources estimated at 6.4 million ounces of gold and inferred resources of approximately 900,000 ounces of gold (see Note 1 below). A feasibility study for an open pit, heap leach operation at Goldfield will be completed this summer and a feasibility study for a similar type of mining operation at Converse will be completed by the end of 2013.

With respect to the sale of the Ruby Hill Royalty, Stephen Kay, Present/CEO of IMZ, commented: "We are very pleased to have concluded this royalty sale with Royal Gold. The proceeds of the sale repay 95% of the recently-matured Cdn$40 million in convertible debentures and help to replenish the Company treasury without recourse to any type of debt or equity financing. In addition, when the $60 million acquisition cost of Metallic is off-set against the total cash received by IMZ from the Ruby Hill Royalty (totaling approximately $48 million), the net acquisition cost per estimated M&I gold ounce at Goldfield and Converse is less than $2.00, excluding the benefit of any of the inferred resources. We believe that the Royal Gold and Metallic transactions illustrate well IMZ 's ability and commitment to corporate growth and enhanced shareholder value with minimal share dilution at a cost well below the typical industry norm."

The Company expects to record a gain on disposition of approximately $28 million with respect to the current carrying value of the Ruby Hill Royalty in its financial statements for the quarter and fiscal year ending June 30, 2012. In addition, the Company expects that US federal and state income taxes will not be payable on proceeds from the sale of the Ruby Hill Royalty.
