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.
Total copper production was 105.7 million pounds (approximately 47,929 tonnes) in 2024 which increased by 139% from 44.2 million pounds (approximately 20,051 tonnes) for the same period in 2023.

LOOKING FORWARD:
Exploration
In 2025, Jiama has carried out exploration work in the mine deep and peripheral areas of the Jiama mining area, completing a total of 1,254 cubic meters of pit exploration, 4,870 meters of underground drilling, and 25,450 meters of surface drilling. The main results have been achieved as below: 1. further controlling the main skarn orebody of the interlayered structure in the Jiama mining area, defining the skarn orebodies in the surrounding contact zone; 2. two gold mineralization zones, one zinc mineralization zone, and one molybdenum mineralization zone have been defined at Bayi Ranch prospecting area. Since the consolidation of mineral rights in Jiama area, the Jiama Mine has completed a total of 297,720 meters of drilling with 622 holes.
Guidance Highlights for 2026:
- The copper production will be approximately between 140 million pounds (63,500 tonnes) and 149 million pounds (67,500 tonnes);
- The gold production will be approximately between 70,732 ounces (2.2 tonnes) and 75,554 ounces (2.35 tonnes);
- The silver production will be approximately between 4.18 million ounces (130tonnes) and 4.82 million ounces (150 tonnes).
