VENUE: 1st Floor, Rugby Club, Rugby (Crane) Place, Sydney
SPEAKER: Mr Xiao Zhenmin, Ausmindex NL
TOPIC: “Major Non-Ferrous Metal Deposits in China”
China is one of the largest mineral producing countries in the world with several non-ferrous minerals and coal resources taking the lead in the world. The talk will give a brief presentation about several world class or representative copper, zinc-lead, and tin deposits in China covering their geology, exploration history and metallogenic models.
The presentation will include:
*The largest Dexin porphyry copper in China (1 billion tons 0.5% Cu 0.12g/t Au);
*The so-called “3 in 1” copper model (contact skarn, stratiform and porphyry) in the Yangtze Valley copper belt (1Bt, 1% Cu);
*Ashele VMS copper deposit in acid volcanics (37Mt, 2.4% Cu 1.2% Zn 0.48g/t Au);
*Lanping zinc-lead deposit in Eogene clastic sediments (149Mt, 7.9% Zn, 1.6% Pb);
*Qixiashan zinc-lead-silver deposit (22Mt, 5.6% Zn, 3.2% Pb, 68g/t Ag) about its metallogenic model related to unconformable contact and palaeo karst;
*Dachang tin-zinc-antimony deposit (80Mt, 1% Sn, 3.5% Zn, 3% Sb) about its interesting “Three Storeys” exploration model.
