High temperature magmatic hydrothermal porphyry copper-gold deposit.
Porphyry Cu: 3.2 Mt @ 0.51%; Au: 50.1 t @ 0.2 g/t

The stratigraphic sequence in the Duobuza mining area predominantly consists of the Upper Cretaceous Abushan Formation (K2a) and the Lower Cretaceous Meiriqiecuo Formation (K1m), with additional exposures of the Mugagangri Formation (JM) and Quaternary deposits (Q). The primary ore-bearing rock is granodiorite porphyry, mainly exposed in the northeastern and southwestern parts of the mining area. Mineralization is primarily developed within the granodiorite porphyry and its contact zone with the surrounding rocks. The Duobuza deposit displays a characteristic zonation pattern extending outward from the porphyry stock: potassic alteration zone (overprinted peripherally by argillic and sericitic alteration) → phyllic alteration zone (largely overprinted by argillic alteration) →propylitic alteration zone → hornfels zone, demonstrating the typical alteration zoning of a porphyry deposit.

Mineralization in the Duolong porphyry deposits is primarily hosted within the orebearing porphyry and its contact zone with the wall rock. High-grade copper–gold mineralization is associated with potassic alteration, while large-scale lower-grade copper– gold mineralization is linked to both potassic and chlorite–sericite alterations. Two major episodes and four hydrothermal stages for the Duolong porphyry deposits, namely the magmatic episode and the hydrothermal episode, with the latter subdivided into the potassic alteration stage, chlorite–sericite alteration stage, propylitic alteration stage, and sulfide-bearing vein stage.

The exposed strata mainly comprise the Upper Cretaceous Abushan Formation (K2a) and the Lower Cretaceous Meiriqiecuo Formation (K1m), with minor occurrences of the Mugagangri Group (JM) and Quaternary sediments (Q). The deposit is primarily controlled by regional east–west-trending structures and Mesozoic magmatic activity, with ore bodies mainly hosted in granodiorite porphyry and its surrounding sandstone. Magmatic rocks in the district is dominated by granodiorite porphyry, as a main ore-bearing rock. The emplacement and mineralization ages of the Duobuza deposit are constrained to approximately 120–118 Ma. A typical porphyry-type alteration system is developed, exhibiting clear zoning both horizontally and vertically, with K-feldspar-rich potassic alteration at depth, sericite alteration at intermediate levels, and chlorite alteration at the outermost levels, locally overprinted by hornfels alteration.
