Jiama Copper Gold Polymetallic Mine

The Jiama project is one of the largest copper gold polymetallic mines in China. The Jiama project is located within the Gangdise Copper Metallogeny Belt in Central Tibet, China and is approximately 60 kilometers east of Lhasa City along the Sichuan-Tibet Highway. The Jiama project is a large scale polymetallic deposit consisting of copper, molybdenum, gold, silver, lead and zinc.

The Company acquired the Jiama project on December 1, 2010 concurrent with the closing of its initial public offering and listing on the Stock Exchange of Hong Kong Limited. Commercial production began at the Jiama project in September 2010.

Phase I development was completed at the Jiama project in 2010 and included two open pits, a processing plant and an underground ore transportation system. 

Phase II expansion started commercial production on July 1, 2018. Jiama Mine’s Phase II consists of two series, Series I and Series II, each having a mineral processing capacity of 22,000 tpd.  The full design capacity of ore processing at Jiama Mine will increase to 50,000 tpd from the previous capacity of 28,000 tpd once Series II reaches full design capacity.

  • Open-pit and underground mines operation
  • A large, skarn-type and porphyry copper polymetallic deposit with well-developed hornfels-type mineralization located in the Gangdise Copper Metallogeny Belt
  • Principal product: Copper with gold and silver credits
  • Commercial production of Jiama Phase II Expansion commenced July 3, 2018
  • With Jiama continues to ramp up operations at Phase II expansion to full design capacity, the copper production in 2019 is expected to reach to approximately 132 million pounds.
  • Expected life of mine: 35 years
  • According to the feasibility study, production is expected to grow to 176 million pounds of copper per year when reach full design processing capacity


2020 Q1 Financial Performance Snapshot

Table 1

  • During the three months ended March 31, 2020, the Jiama Mine produced 16,185 tonnes (approximately 35.7 million pounds) of copper, an increase of 9% compared with the three months ended March 31, 2019 (14,833 tonnes, or 32.7 million pounds). Both total production cost of copper per pound after by-products and cash production cost of copper per pound after by-product decreased as compared to the same period in 2019 due to higher recovery rates of copper. The increase in production and lower production cost are due to higher mined tonnes and higher recovery rates of copper.

2020 Q1 Production Update

Table 2

  • During the first quarter of 2020, the metals recovery rates were increased significantly, with an increase of 6% for copper, based on the continued optimization of operating parameters and regime of agent, as well as the amelioration of steady flowsheet.

There is no exploration program with diamond drilling on site in the first quarter of 2020, with data processing and geological interpretation for the exploration programs conducted in 2019 and previous years. An infill diamond drilling program focused on the well mineralized zones, however, will be conducted based on the surface drilling program completed in 2019. The mineralization interceptions and sample assaying of 2020 infill drilling will be analyzed together with 2019 exploration results to increase and upgrade Mineral Resources.

Guidance Highlights for 2020:

  • Projected gold production of 212,000 ounces in 2020, which remained consistent with the 2019 production.
  • Projected copper production of 145 million pounds in 2020, which is a 5% increase of 2019 production.
  • The Company continues to focus its efforts on optimizing the operation at both mines and improving the profitability of both mines.
  • To fulfill its growth strategy, the Company is continually working with China National Gold Group Co., Ltd. and other interested parties to identify potential international mining acquisition opportunities, namely projects outside of China.
  • The Company has not experienced any significant impact on its operations from the novel coronavirus but continues to closely monitor the health of its employees and supply chains to be able to respond to any potential disruptions, should any arise.
