Nature Of Operations And Basis Of Presentation	1. Nature of Operations and Basis of Presentation Vista Gold Corp. and its subsidiaries (collectively, “Vista,” the “Company,” “we,” “our,” or “us”) are engaged in the gold mining industry.

We also hold 11.2% of the outstanding common shares in the capital of Midas Gold Corp. (“Midas Gold Shares”), non-core projects in Mexico and the United States, and royalty interests in projects in Bolivia and Indonesia.  The interim Condensed Consolidated Financial Statements (“interim statements”) of the Company are unaudited.
