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, Tibet Huatailong Mining Development Co., Ltd. planned to continue implementing geological exploration programs in the surrounding area of Jiama mining permit and the Bayi pastureland area. The planned work includes surface diamond drilling of 34,510 meters with 38 holes (including possible extra 3,700 meters), geological survey of 5 square kilometers, profile survey of 20 kilometers, and soil survey of 5.9 square kilometers. The estimated total budget was RMB 75.5967 million. As of the end of the third quarter of 2025, It had completed 15,033 meters of diamond drilling (19 boreholes), 10 kilometers of access road construction, geological surveying covering 5.51 square kilometers, profile surveying covering 2.5 kilometers, and soil surveying covering 5.9 square kilometers in the geological exploration program in the surrounding area of the Jiama Mine and the Bayi Pastureland area, with a total investment of RMB 25.3518 million.
