The amounts disclosed as mineral properties as of December 31, 2010 differ from those previously presented in the U.S. GAAP reconciliation to our Canadian GAAP financial statements by $2,206. This amount represents option payments expensed as incurred in the years 2002 to 2006, which have been treated as property acquisition costs in these consolidated financial statements prepared in accordance with U.S. GAAP.

On April 6, 2011, the Combination with Midas Gold was completed. As part of the Combination, Midas and Vista US contributed each of their respective gold assets in the Yellow Pine-Stibnite District in Idaho to Midas Gold. See Note 3.

On June 13, 2011, our subsidiary Vista Gold (Barbados) Corp. (“Vista Barbados,”) entered into an additional option agreement (“Additional Option Agreement”) with Pan Asia Resources Corp. (“Pan Asia”). The Additional Option Agreement provides Pan Asia with the opportunity to earn an additional 20% interest in our Awak Mas gold project in Indonesia after it has earned a 60% interest in the project pursuant to the JV Agreement (as defined below). Pan Asia can acquire the additional 20% interest by (a) making cash payments totaling $2,500 over a nine-month period; (b) issuing shares with a value equal to $2,000 or making a cash payment of $2,000 within 12 months, depending on whether Pan Asia completes an initial public offering; and (c) carrying out a 5,000 meter drilling program in an area outside of the current project resource area within 18 months. In September 2011, the Additional Option Agreement and JV agreement were assigned from Pan Asia to Awak Mas Holdings Pty. Ltd. (an affiliate of Pan Asia). During the nine months ended September 30, 2011, Vista received $1,000 under the Additional Option Agreement and has recorded these proceeds as a cost recovery against the carrying value of the Awak Mas gold project. Any further proceeds received under these option agreements will be applied against the carrying value of the Awak Mas gold project until the carrying value is reduced to zero. Any proceeds received in excess of the carrying value of the project will be recorded as a realized gain in the Consolidated Statement of Income/(Loss).

In December 2009, Pan Asia and Vista Barbados executed a joint venture agreement (“JV Agreement”) allowing Pan Asia to earn a 60% interest in the project by: (a) expending $3,000 on the project within a specified period of time; (b) completing an environmental impact assessment and feasibility study (in compliance with Canadian National Instrument 43-101); and (c) issuing to Vista 2,000,000 shares of Pan Asia and the right to purchase up to an additional 2,000,000 shares of Pan Asia in the event Pan Asia completes an initial public offering of its shares. The 2,000,000 shares of Pan Asia received under the JV agreement were subsequently exchanged for equivalent shares of One Asia Resources Ltd.

If Awak Mas Holdings Pty. Ltd. completes the undertakings required in the JV Agreement and the Additional Option Agreement, it will hold an 80% indirect interest in the Awak Mas gold project.

In September 2011, the Company acquired some additional land from a third party for $1,150 as part of Vista's efforts to advance the Concordia gold project. Vista paid $538 in cash, while the remaining $612 is due upon the achievement of certain milestones and is included in accrued liabilities and other on our Consolidated Balance Sheet.

The recoverability of the carrying values our mineral properties is dependent upon the successful start-up and commercial production from, or the sale or lease of, these properties, and upon economic reserves being discovered or developed on the properties. Development and/or start-up of any of these projects will depend on, among other things, management's ability to raise additional capital for these purposes. Although we have been successful in raising such capital in the past, there can be no assurance that we will be able to do so in the future.

We have determined that no impairment provision is currently required. A write down in the carrying values of one or more of our mineral properties may be required in the future as a result of events and circumstances, such as our inability to obtain all the necessary permits, changes in the legal status of our mineral properties, government actions, the results of technical evaluation and changes in economic conditions, including the price of gold and other commodities or input prices. We regularly evaluate the carrying value of our mineral properties to determine if impairment is required in view of such factors.
