The Yanbei porphyry tin deposit of Jiangxi Province, China, is located on the eastern margin of of the south-east China Caledonian fold belt, intruding a Late Jurassic granitoid batholith and is overlain by Late Cretaceous red beds.

It is found along the contact between topaz bearing granite porphyry and rhyolite porphyry and comprises a single orebody containing cassiterite, pyrite and chalcopyrite, lesser sphalerite, wolframite and galena and minor siderite, molybdenite and stannite.   Intense wall rock alteration includes topaz-quartz, chlorite and sericite zones, with the ore mainly in the first two.

Tin grades range from 0.5 to 1.5% Sn, with 0.13 to 0.4% Cu.
