The Dingan Gold & Polymetallic Project, Hainan
Highlights
· The four contiguous exploration permits, totaling 165.4km2, are 100% owned by HT Mining (Beijing)
Limited Company;
· The high grade Au-Ag orebodies in the FW Gold Mine, which is encompassed by our properties, is of high
grades ranging from 10-200g/t, averaging 52.36 g/t Au, 153.37g/t Ag, with significant Pb-Zn of up to 12%;
· The nearby FW orebodies are up to 650m long, extending from the surface to over 400m in depth. The
multiple layers of orebodies occur at very low angle of 10-38 degrees dipping NE;
· The regional and more detailed geochemical work have shown strong anomalous of Au, Ag, Cu, Pb, Zn,
As, Sb, Hg at large scales. Detailed geophysical work results are interpreted as a granodiorite underlying
the sandstones leading to the gold and silver mineralization.
Overview
The DingAn gold and polymetallic exploration project is located in DingAn County, which is about 40 km
south of Haikou, the capital city of the Hainan Island Province. The main road runs through most of the
prospect areas. The four exploration permits of the DingAn gold and polymetallic project of 165.4 km2
are 100% owned by HT Mining (Beijing) Limited Company. We have carried out significant amount of
geochemical and geophysical work in the last two years.
Regional Geology
The properties are located in the northern part of the Hainan Island, tectonically belonging to the northern
Leiming RIFT within in the Wuzhishan Uplift, which is part of the Southern ChinaFold. Regional stratigraphy
is simple, with Cretaceous sandstone being the main rock unit; and widespread igneous rocks of
PermianCretaceous age are outcropped in the southwest area.This area has good geological
mineralization background for gold, and uranium.
Property Geology
Stratigraphy in the mining area is simple, being the Cretaceous Lumuwan Group; Tertiary basalt cover
and some basic dyke intrusions. In the SW area, there are some Mesozoic granites. The structures in the
mining area are dominated by three groups trending NW, EW and NNW. The NW-trending group is the
fault caused by interlayer sliding, trending NW and dipping NE @ 10~25. It’s the major mineralization
structure in this area, controls ore body V14V15V17 in the nearby FW Mine. The EW-trending group
is a group of extending structure obliquely cross the rocks beds; the scale is small and extending is limited,
controls ore body V1V4V13 in the nearby FW Mine; and dipping North @ 25~37. The NWN-trending
group is a regional structure. It consists of a number of parallel or intermittent linear distribution fracture
zones. The typical one is F2, being a normal fault, up to 440 m long and 1~5 m wide, trending 230 and
dipping 78.
Small granodiorite and granite intrusions of the late Mesozoic age are exposed near the ore bodies V17
and V14 in the FW Mine. The Granodiorite is ovalshaped, the exposed intrusion is some 0.12 km2, and it
has intrusive relations with Cretaceous rock units. There are some pyrites and auriferous quartz veinlets
occur in the inner contact zone. Gold mineralization may have spatial relationships with these intrusions.
Characteristics of Orebody in Nearby FW Mine
In an area of some 5km2, about 20 gold orebodies have been identified by shafts and trenching in the FW
mining area, which is encompassed by our four properties. The orebodies mainly occur along the sliding
structure betweens the rock layers. They are 70 -650 m long, extending for 360~680 m along the dip,
trending 78¡ã and dipping 10-38¡ã. The thicknesses of the orebodies range from 0.13-3.2m. The ores are
of high grades ranging from 10-200g/t, averaging 52.36 g/t Au, 153.37g/t Ag, with significant Pb-Zn of up
to 12%.
