Sterling Resources Ltd. Announces Mailing of Meeting Materials and Details of Proposed Share Consolidation and Name Change

Calgary, Alberta and Houston, Texas – May 9, 2018—Sterling Resources Ltd. (“Sterling” or the “Company”) (TSX-V: SLG) is pleased to announce that it has mailed a management information circular (the “Circular”) to holders (“Shareholders”) of its common shares (“Shares”) in connection with an annual general and special meeting (the “Meeting”) of Shareholders to be held in the Clarkson & Tétrault Boardroom at the offices of McCarthy Tétrault LLP, Suite 4000, 421 – 7th Avenue S.W., Calgary, Alberta on Wednesday, May 30, 2018 at 10:00 a.m. (Calgary time).

At the Meeting, Shareholders will be asked to consider for approval, among other things, a resolution authorizing a consolidation of the Shares on the basis of a ratio of between four and eight pre-consolidation Shares for each one post-consolidation Share (the “Consolidation”) and a resolution authorizing a change of the Company’s name to “PetroTal Corp.” (the “Name Change”).

CONSOLIDATION

The Company has experienced a significant increase in its share count as a result of the reverse take-over with PetroTal Ltd. (“PetroTal”) and the acquisition of Gran Tierra Energy International (Peru) Holdings B.V., an indirect wholly-owned subsidiary of Gran Tierra Energy Inc., completed on December 18, 2017. The Company wishes to reduce the outstanding share amount to a level more in keeping with its industry peers. The Company believes the Consolidation will provide a share capital structure that will better attract investors and enhance future growth opportunities. The exact Consolidation ratio will be determined by the board of directors of the Company (the “Board”) when the Board considers it to be in the best interests of the Corporation to implement such a Consolidation. Notwithstanding approvals being received, the Board may determine not to proceed with the Consolidation, at its discretion.

The Company currently has 537,740,991 issued and outstanding Shares. In the event that the Consolidation is completed, for example, on a four for one basis, the Company would have approximately 134,435,248 Shares outstanding following the Consolidation. In addition, the exercise price and number of Shares issuable upon the exercise of outstanding convertible securities, including purchase warrants, will be proportionally adjusted upon the implementation of the Consolidation.

NAME CHANGE

The Company proposes to change its name to “PetroTal Corp.” to reflect its current business activities. Prior to the reverse take-over, PetroTal actively pursued opportunities in Latin America, specifically Peru, since inception in 2016.  The Company’s management team is known by local officials and counterparties in Peru as PetroTal and the management team believes the name has value in the country.

Approval of the Consolidation and Name Change by Shareholders would, subject to approval of the TSX Venture Exchange (the “TSX”), allow the Board to implement the Consolidation and Name Change without any further action on the part of Shareholders.

Further details with regard to the background, reasoning and impact of the Consolidation and the Name Change, are contained in the Circular dated April 30, 2018, a copy of which is available on SEDAR at www.sedar.com.
