On July 25, 2016, Golden Queen Mining Co. Ltd. (the “Company”) in connection with its closing of an offering of units of the Company entered into a warrant indenture (the “Warrant Indenture”) between the Registrant and Computershare Trust Company of Canada, as the warrant agent.

Under the terms of the Warrant Indenture, each whole common share purchase warrant (each a “Warrant” and collectively, the “Warrants”) entitle the holder (the “Warrant holder”) to purchase one common share of the Company upon the exercise of the Warrant (each a “Warrant Share” and collectively, the “Warrant Shares”) at a price of C$2.00 per Warrant Share. The Warrants will be exercisable at any time prior to 5:00 p.m. (Vancouver time) on July 25, 2019 (the “Expiry Time”), after the Expiry Time, the Warrants will expire and become null and void. The exercise price for the Warrants is payable in Canadian dollars.

The Warrant holders are entitled to a “cashless exercise” option if, at any time of exercise, there is no effective registration statement registering, or no current prospectus available for, the issuance or resale of Warrant Shares under the United States Securities Act of 1933, as amended. This option entitles the Warrant holders to elect to receive fewer Warrant Shares without paying the cash exercise price. The number of Warrant Shares to be issued would be determined by a formula based on the total number of Warrant Shares with respect to which the Warrant is being exercised, the daily volume weighted average price for the Company’s common shares on the trading day immediately prior to the date of exercise and the applicable exercise price of the Warrants.

The exercise price and the number of Warrant Shares issuable upon the exercise of each Warrant are subject to adjustment upon the happening of certain events, such as a distribution on the common shares, or a subdivision, consolidation or reclassification of the common shares. In addition, upon any fundamental transaction, such as a merger, consolidation, sale of all or substantially all of our assets, share exchange or business combination, the Warrants will thereafter evidence the right of the holder to receive the securities, property or cash deliverable in exchange for or on the conversion of or in respect of the common shares to which the holder of a common share would have been entitled immediately on such event.

The foregoing summary of the material provisions of the Warrant Indenture is qualified in its entirety by reference to the Warrant Indenture, a copy of which is filed as Exhibit 4.1 to this Current Report on Form 8-K and which is hereby incorporated by reference into this Item 1.01.

On July 25, 2016, the Registrant issued a press release entitled “Golden Queen Closes C$14 Million Unit Offering” A copy of the press release is attached to this report as Exhibit 99.1. In accordance with General Instruction B.1 of Form 8-K, the information set forth herein and in the press release is deemed to be “furnished” and shall not be deemed to be “filed” for purposes of the United States Securities Exchange Act of 1934, as amended. The information set forth in Item 7.01 of this report shall not be deemed an admission as to the materiality of any information in this report on Form 8-K that is required to be disclosed solely to satisfy the requirements of Regulation FD.
