VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 15, 2017) - Gold Standard Ventures Corp. ("Gold Standard") (TSX VENTURE:GSV)(NYSE MKT:GSV) and Battle Mountain Gold Inc. (TSX VENTURE:BMG) ("Battle Mountain") are pleased to announce that Battle Mountain has completed the mailing of its notice of meeting, management information circular and related proxy materials (collectively, the "Meeting Materials") to Battle Mountain securityholders in respect of the previously announced Plan of Arrangement (the "Arrangement") involving Battle Mountain, its securityholders and Gold Standard pursuant to which Gold Standard will acquire all of the outstanding common shares of Battle Mountain (other than those already owned by Gold Standard). Approval of the Arrangement will be sought at a special meeting of Battle Mountain securityholders (the "Meeting") to be held on June 8, 2017 at 10:00 am (Vancouver Time) at the offices of Dentons Canada LLP, 20^th Floor, 250 Howe Street, Vancouver, British Columbia, Canada, V6C 3R8.

Battle Mountain shareholders, optionholders and warrantholders on record as of May 9, 2017 will receive the Meeting Materials in advance of the Meeting and are asked to vote, by proxy or in person, on the approval of the Arrangement at the Meeting. The Meeting Materials include a management information circular (the "Circular") that contains, among other things, details concerning the Arrangement, the reasons for and benefits of the Arrangement, the risks associated with the Arrangement, the requirements for the Arrangement to become effective, voting at the Meeting and other related matters. Certain reasons for and benefits of the Arrangement include:

• Premium - The consideration offered under the Arrangement values Battle Mountain at approximately $0.59 per Battle Mountain share, which represents a 97% premium to the volume weighted average price of Battle Mountain shares on the TSX-V for the 20-day period prior to April 11, 2017 (the last trading day prior to the announcement of the Arrangement), a 62% premium to the volume weighted average price of Battle Mountain shares on the TSX-V for the 5-day period prior to April 11, 2017 and a 47% premium to the closing price of Battle Mountain shares on the TSX-V as at April 11, 2017.

• Holdings in Larger Entity - The Arrangement will offer Battle Mountain securityholders the opportunity to participate in the future potential of Gold Standard, a leading gold explorer and developer with a portfolio of highly prospective exploration and development assets, superior liquidity, improved ability to obtain financing and a broad institutional following.

• Increased Asset Diversification - The Arrangement will provide Battle Mountain securityholders with the opportunity to diversify from Battle Mountain's single asset profile and provides exposure to Gold Standard's growing portfolio of Nevada assets.

• Enhanced Market Presence - The Arrangement will provide Battle Mountain securityholders with the opportunity to hold shares in a company with significantly greater analyst coverage and share liquidity than currently enjoyed by Battle Mountain.

• Fairness Opinions - Each of Haywood Securities Inc. and Evans & Evans, Inc. have provided written opinions to the effect that, as at April 11, 2017, the consideration to be received by Battle Mountain shareholders pursuant to the Arrangement is fair, from a financial point of view, to Battle Mountain shareholders (other than Gold Standard and its affiliates).

Battle Mountain's Board of Directors has unanimously determined (with an interested director abstaining) that the Arrangement is fair to Battle Mountain securityholders and that the Arrangement is in the best interests of Battle Mountain and has recommended Battle Mountain securityholders vote in favour of the Arrangement.

Securityholders are urged to carefully review the Circular and accompanying materials as they contain important information regarding the Arrangement and its consequences to securityholders. Copies of the Meeting Materials may also be found under Battle Mountain's profile on SEDAR at www.sedar.com.

If the Arrangement receives the requisite approval of Battle Mountain securityholders at the Meeting, then a final hearing on the Arrangement will be sought from the Supreme Court of British Columbia on or about June 12, 2017. Assuming all other closing conditions are satisfied or waived, the Arrangement is expected to close on or about June 14, 2017.

The Company has successfully consolidated the southern end of the Carlin Trend by patiently assembling a 208 sq. km. (80 sq. mi.) land position containing four gold deposits, two of them discovered by Gold Standard. The 2014 Pinion and Dark Star gold deposit acquisitions offer Gold Standard a potential near-term development option and further consolidates the Company's premier land package on the Carlin Trend. The Pinion deposit now has an NI 43-101 compliant resource estimate consisting of an Indicated Mineral Resource of 31.61 million tonnes grading 0.62 grams per tonne (g/t) gold (Au), totaling 630,300 ounces of gold and an Inferred Resource of 61.08 million tonnes grading 0.55 g/t Au, totaling 1,081,300 ounces of gold, using a cut-off grade of 0.14 g/t Au (announced March 15, 2016).
