Item 1.01 Entry into a Material Definitive Agreement

Underwriting Agreement

On August 2, 2016, Vista Gold Corp. (the “Registrant”) entered into an underwriting agreement (the “Underwriting Agreement”) by and among the Registrant and Cantor Fitzgerald Canada Corporation (“CFCC”) and Rodman & Renshaw a unit of H.C. Wainwright & Co., LLC (together with CFCC, the “Co-Lead Underwriters” and acting as joint bookrunners), for a syndicate of underwriters, including Sprott Private Wealth LP, Roth Capital Partners, LLC and Jett Capital Advisors, LLC, acting as co-managers (collectively with the Co-Lead Underwriters, the “Underwriters”). The Underwriting Agreement relates to the offer and sale in the United States and Canada of up to 10,750,000 units (the “Units”) of the Registrant at a public offering price of $1.40 per Unit, each Unit consisting of one common share of the Registrant and one half (1/2) of a warrant to purchase a common share at an exercise price of $1.92 per common share. The Registrant has granted the underwriters an option, exercisable at the offering price until one business day prior to the closing date of the Offering, to purchase up to an additional 15% of the base Units offered in the Offering (which may be exercised for Units, Shares, Warrants or a combination thereof) to cover over-allotments, if any, and for market stabilization purposes. The Offering is expected to close on August 8, 2016, subject to obtaining customary TSX and NYSE MKT approvals.

The offering is registered under the Registrant’s shelf registration statement on Form S-3 (Registration No. 333-196527), including a base prospectus dated August 15, 2014, as supplemented by a prospectus supplement dated August 2, 2016. The offering is being made concurrently in Canada pursuant to a Canadian Prospectus and Prospectus Supplement filed with the securities commissions or similar regulatory authorities in the provinces of Canada (except Quebec) for the purpose of qualifying the Units for sale.

The Underwriting Agreement contains customary representations, warranties and covenants by the Registrant, conditions to closing and indemnification provisions, as well as a form lock-up agreement that will be signed by certain of the Registrant’s directors and officers, filed herewith as Exhibit “B” to Exhibit 1.1.

The Underwriting Agreement provides that the Registrant will pay the Underwriters cash compensation in amount equal to 6% of the aggregate gross proceeds of the offering (3% for Units purchased pursuant to a president’s list) and warrants equal to 3% of the number of common shares issued in the offering (1.5% of the number of common shares issued pursuant to the president’s list), exercisable in the same terms as warrants issued in the offering.

The above description of the material terms of the Underwriting Agreement is qualified in its entirety by the full terms and conditions of the Underwriting Agreement, attached hereto as Exhibit 1.1 and incorporated herein by reference.
