The exploration activities at Dapingzhang have been extremely successful in laying the foundation of a robust resource model and allowing a structured mine plan to be developed. It has been the success of the exploration that has underpinned the continuing development of Dapingzhang.
Exploration at the Dapingzhang Mine has been extremely aggressive. The focus of the exploration program was to increase the confidence in the mine resources of high grade massive sulphide mineralisation (V1) and lower grade disseminated mineralisation (V2). This program confirmed the prior resources converting 99% of the 43.8m tonne ore body into the measured and indicated categories.
The deposit has extension potential to the South-East, North-East, North-West and North, which will continue to be explored.
As mining progresses and increased exposures are realised in the open pits the structural interpretation will be confirmed and used as a key tool in the identification of future target areas. At this early stage of knowledge, deposit geometry is explained by:
Volcanogenic massive sulphide copper-zinc mineralisation with gold and silver tenors is now known to occur along a north/south strike length of four kilometres and is open in both directions as well as down dip.
In total the Joint Venture Company holds five contiguous exploration licenses covering 97.6km² and one mining licence covering 2.76km². Regent also holds a 97.5% interest in the contiguous 36.41km² Hengyu Exploration License, which also adjoins the 21.1km² Rixin License (Oz Metals 25%).
Exploration in the Simao Regent Minerals licences adjacent to Dapingzhang has commenced and similar lithological sequences to those that host the Dapingzhang Mine have been identified.

- gentle folding about a shallow northwest plunging axis, the east limb of which is steeper than the west limb or
- sulphide mounds developed at intervals along the top of an irregular northwest trending elongate rhyolite 'dome'. A contemporaneous northwest trending 'growth fault' severed to focus both rhyolite feeder dykes, and hydrothermal sulphide mound building fluids. This 'growth fault' (east side down) formed a half graben (or west side of a full graben not yet discovered).
