The Jinfeng Gold Mine is a large gold‑copper mining operation located in the province of Guizhou, southwestern China. The mine is situated near the town of Jinfeng in the county‑level city of Jingxi, approximately 250 km west of the provincial capital, Guiyang.
Ownership and operation
The mine is owned and operated by China Gold International Resources Ltd. (CGIR), a subsidiary of China National Gold Group Corp., the largest state‑owned gold producer in China.
History
Exploration of the Jinfeng deposit began in the early 2000s, and feasibility studies were completed in 2005. Commercial production commenced in 2007 with an open‑pit mining method, and underground development started in 2010 to extend the resource base.
Production
Jinfeng is one of China’s major gold producers. Annual gold output has varied between 200,000 and 300,000 troy ounces, with concurrent production of copper concentrate averaging several hundred thousand tonnes of copper metal equivalent per year. The mine’s concentrate is processed at the nearby Jinfeng Processing Plant, which employs conventional flotation and leaching techniques.
Geology
The Jinfeng deposit is hosted in a Neoproterozoic granite‑related porphyry system. Mineralisation is characterized by disseminated gold‑bearing sulfides (chiefly chalcopyrite and pyrite) within quartz‑monzonite intrusions and associated stockworks. Alteration assemblages include potassic, phyllic, and argillic zones, typical of porphyry‑type ore bodies.
Infrastructure
The mine includes an open‑pit, a network of underground drifts, a concentrate processing plant, tailings storage facilities, and supporting infrastructure such as power sub‑stations, water treatment plants, and a worker camp. Access to the site is provided by a paved highway linking Jinfeng to regional transport corridors.
Environmental and social aspects
Operations at Jinfeng are regulated under Chinese mining and environmental legislation. The company reports compliance with waste‑management standards, including tailings dam monitoring and water quality controls. Community engagement programs focus on local employment, vocational training, and contributions to regional development projects.
Economic significance
As a high‑grade, relatively low‑cost producer, Jinfeng contributes materially to China’s domestic gold supply and to the export revenues of its parent corporation. The mine’s output supports both the national gold market and the broader global supply chain for gold and copper.
