Abstract: Banbianshan gold-bearing porphyry bodies are discovered in the middle proterozoic Lengjiaxi group in the exocontract of granodiorite, and comprise nine bodies trending NNB. Gold mineralization is concentrated mainly in quartz veins, contact fracture zone and alteration zones in the porphyry bodies. The gold mineralization of enrichment is intermittently extending about 150-250m long and 0.47-1.56m whick with a Au content of 1.5×10^-6-1.67×10^-6 Artificial heavy concentrate shows that the gold is represented by fine grain of native gold. This discovery gives not only the possibility to increasea new type of gold deposit in Hunan, but also new evidence of the relation between W-Sb-Au belt magmatic rocks in Xuefensr uplift of western Hunan.
