W-Sn-Bi-Mo-F skarn deposit, hosted by Devonian limestone in the thermal aureole of the Qianlishan granite complex. The latter comprises five separate intrusions, including fine-grained porphyritic biotite granite (granite 1), medium-grained biotite-K feldspar granite (granite 2), fine-grained biotite and K feldspar granite (granite 3), granitic porphyry (granite 4), and diabase. Its upper part is characterized by extensive greisen alteration. Skarn zones distributed around the intrusions are mainly calcic. Mineralization consists of Sn-Be veinlet ore in marble and porphyry, massive W-Bi-Mo-Sn skarn ore, stockwork W-Sn-Bi-Mo-F ore, and W-Sn-Mo-Bi greisen ore, mainly associated with granite 2. Emplacement of granite 2 was accompanied by late, intense fracturing characterized by stockwork mineralization, which was superimposed on massive skarn and greisen zones. The stockwork ore consists mainly of greisen and skarn veins and veinlets with scheelite, wolframite, molybdenite, cassiterite, bismuthinite, and fluorite.

Ore reserves amount to 750,000 tonnes of WO3 ore, 490,000 tonnes of Sn ore, 300,000 tonnes of Bi ore, 130,000 tonnes of Mo ore and 200,000 tonnes of Be ore, with combined grades ranging from 1% to 5%. In addition, there are fluorite reserves of 7,000 tonnes, making it one of the largest associated fluorite deposits in China.

Located about 15 km SE of Chenzhou City.
