The Julong project has a world-class, large-scale, and low-grade porphyry copper-molybdenum deposit.
The Phase I project of the Julong Copper Mine has been put into operation.
It is planned to implement the construction of Phase 2 and Phase 3 in stages. After the construction is fully completed the mining and processing volume will be around 200 million tonnes of ore per annum and output of copper will be 600 thousand tonnes per annum. |

Summary:
The projects are situated in the northern mountain foot of western Guokalariju, eastern lower mountain of the Gangdise Mountains. It is precipitous. The southern part is high while the northern part is low with a strong cutting and glacier landform. The highest altitude is 5,566m. The elevation of the base level of erosion near the mining area is approximately 3,900m. The vegetation at the gullies and two sides is mainly high-mountain meadow. There is basically no tree and the vegetation is simple.
The Qulong porphyry-type copper and molybdenum deposit is located at the Gandise metallogenic belt of the Tethys-Himalayan metallogenic province, one of the main porphyry-type copper mine metallogenic provinces in the world. The existing Qulong Copper and Polymetallic Mine and the Rongmucuola Copper and Polymetallic Mine in the deposit are a complete porphyry-type copper deposit with a burial depth of 3 to 96m, which is generally a concealed to semi-concealed deposit. The deposit is east-west oriented with length of 2.27km, width of 1.50km from north to south in an oval shape. The ore is mainly structured by veinlet-disseminated orebody.
Summary:
As the deposit is large, thick, shallowly buried with partially exposed surface, the stripping ratio for open-pit mining is low, which is suitable for large-scale open-pit mining. They was designed as one pit for open-pit mining.
847 million tonnes of ores will be mined and utilised in phase 1, at Cu 0.42%, Mo 0.022%. The average stripping ratio will be 0.26t/t. After completion of phase 1 construction, the annual production will be 165 thousand tonnes of copper and 6,200 tonnes of molybdenum.
Mining scope: above 4,500m (mining permit for above 4,452m).
Boundary length: 2,900m × 2,650m.
Elevation of the pit bottom: 4,500m.
Elevation of entrance and exit of the trench: 5,010m.
Slope angle: 39 - 44 degrees.
