China Gold International Resources Co. Ltd. Updates CSH Production Schedule
VANCOUVER, July 29, 2019 - China Gold International Resources Co. Ltd. (TSX:CGG; HKEx: 2099) (“China Gold International Resources” or the “Company”) is pleased to announce an updated mine plan and life of mine production schedule for its Chang Shan Hao Gold Project (“CSH Mine”) located in Inner Mongolia, People's Republic of China.
Background
As previously reported, in the second half of 2017 there were a series of wall failures on one side of the north-east pit at the CSH Mine that led to short term interruptions of mining activities. For safety reasons the Company curtailed production in certain areas of the pit while it conducted studies to address the slope stability issues and remediation plans for the long term mine plan for the CSH Mine.
The Company engaged teams at the State Key Laboratory for GeoMechanics and Deep Underground Engineering (China University of Mining and Technology) and the Changchun Gold Design Institute to complete studies on the slope stability of the north-east pit and the updated mine plan for the new pit slopes, including optimization studies for pit limit, haul road design and mining production schedule for the new pit slope angle.
The Company has finalized and adopted these studies into the ongoing mining operations at the CSH Mine. Due to the fact that the CSH Mine employed a phase mining approach, and the 2017 pit wall failures occurred at the transition wall rather than the final wall, it is expected that the ultimate pit limit based on the changed pit slope angle will provide a sustainable mining production of the north-east pit.
Slope Stability Study
Based on a slope stability study conducted by the State Key Laboratory for GeoMechanics and Deep Underground Engineering (China University of Mining and Technology), the Company has adopted the new recommended final pit slopes of the north-east pit of 36.5 degrees (from 42 degrees) for the south wall and 38 degrees (from 44 degrees) for the north wall, respectively, as detailed in the Figure below.

Pit Design
The Company has adopted an updated pit design for north-east pit in accordance with the pit limit optimization study carried out by Changchun Gold Design Institute based on the amended ultimate pit limit slopes, as shown in the Figure below.

Production Schedule
The new pit design is conducted based on the Mineral Reserves estimate for the CSH Mine reported as of December 31, 2018 in the Company’s Management Discussion and Analysis for the year ended December 31, 2018.
In accordance with the updated design of north-east pit, the life of mine updated production schedule is seven years, as listed in the Table below.

Note: The figures in 2019 include the southwest pit of the CSH Mine.
The Company continues to assess underground development plans for the mineralization extending below and around the ultimate pit limit at the CSH Mine. The Company is also conducting exploration around the CSH Mine to identify additional resources that may further extend the mine life.
Qualified Person
Disclosure of scientific or technical information in this production schedule update was approved by Mr. Zhongxin Guo, P.Eng., the Company’s Chief Engineer and a Qualified Person (“QP”) for the purposes of NI 43-101.
