Nature Of Operations And Basis Of Presentation	1. Nature of Operations Vista Gold Corp. and its subsidiaries (collectively, “Vista,” the “Company,” “we,” “our,” or “us”) operate in the gold mining industry. We are focused on the evaluation, acquisition, exploration and advancement of gold exploration and potential development projects, which may lead to gold production or value adding strategic transactions such as earn-in right agreements, option agreements, leases to third parties, joint venture arrangements with other mining companies, or outright sales of assets for cash and/or other consideration.  We look for opportunities to improve the value of our gold projects through exploration drilling and/or technical studies focused on optimizing previous engineering work. Our principal asset is our flagship Mt Todd gold project in Northern Territory (“NT”), Australia. We also hold 11.2% (reduced to 5.5% during March 2015, Note 19) of the outstanding common shares 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.
