Rent consists of a base rent amount and certain items of additional rent.

On December 10, 2010, we entered into an agreement with Julián Michudis whereby we agreed to purchase the surface rights to a portion of our Pinguino mineral property located in the Santa Cruz Province of Argentina for a purchase price of approximately US$815,000.
