SCOTTSDALE, AZ -- (Marketwire) -- 11/21/12 -- International Minerals Corporation (TSX: IMZ) (SWISS: IMZ) (the "Company" or "IMZ") provides an update with respect to the sale of its Rio Blanco and Gaby properties (the "Properties") in Ecuador.

Following the appointment of North American financial advisors in July 2012 and the implementation of an aggressive marketing program, several companies, both international and local, submitted purchase proposals for Rio Blanco and Gaby.

The Company advises that it has selected a potential buyer for the Rio Blanco property. Finalization of the sales agreement, however, remains pending because prior approval by the Ecuadorian government of the proposed transaction is required. IMZ expects to provide further information with respect to the proposed sale of Rio Blanco within the next few weeks, following meetings with the Ecuadorian government.

The Company also wishes to advise that it has selected a separate potential buyer for the Gaby property. As with Rio Blanco, finalization of the terms of the agreement remains pending. Although formal government approval for the sale of Gaby is not required, the Company intends to consult with the government with respect to the proposed sale of the property.

As a result of the pending sales of the Properties, the Company anticipates that there will be a write-down of the carrying value affecting the Company's earnings for the second fiscal quarter ending December 31, 2012 due to the revised estimate of the net proceeds likely to be received by IMZ from the sale of the Properties. The write-down is estimated by the Company to represent a 30% to 35% decrease in the current approximately $40 million carrying value of the Properties (as at September 30, 2012). Finalization of the sale of the Properties and the Company's subsequent withdrawal from Ecuador in 2013 will, however, eliminate IMZ's future in-country holding costs, which are currently approximately $4 million per year.
