The Huogeqi copper-zinc-lead deposit is located on the northern slopes of the Lang Shan Mountains, within the Mesoproterozoic Langshan-Zha'ertai-Bayun Obo ore belt of Inner Mongolia, approximately 86 km from Dongshengmiao and 450 km west of Hohhot (#Location: 41° 17' 00"N, 106° 51' 00"E).
The deposit is hosted by a Mesoproterozoic meta-sedimentary sequence of the Langshan Group which includes phyllite, schist and quartzite with intercalated meta-basic volcanic rocks (dated at 1100 Ma) within the Langshan-Zha'ertaishan aulacogen along the northern margin of the North China Platform.
The ore lenses are concordant with the host meta-sediments, closely associated with the intercalated volcanics, and occurs as massive and banded sulphides as well as late crosscutting veinlets. The Cu dominated ores are mostly hosted by carbonaceous banded quartzites, while the Pb is associated with carbonaceous slates, limestones and their interbeds and Zn ores tend to favour carbonaceous slates.
The ore minerals are predominantly chalcopyrite, pyrite, pyrrhotite, magnetite, galena and sphalerite, with minor arsenopyrite and hematite.
Wallrock alteration includes silica, diopside-grunerite, biotite, sericite and chlorite.

The deposit is quoted (Inner Mongolian Bureau of Geology & Mineral Resources geologists, pers. comm., 1999) as having a resource of:
96 Mt @ 1.1% Zn, 1.4% Pb, 1.1% Cu.
The deposit is quoted in the Nat. Res. Canada website (2006) as having:
a reserve of: 33.6 Mt @ 1.28% Cu, and
a resource of 43.1 Mt @ similar grade + a deeper Pb-Zn resource.
