HIGH GRADE ZINE STRUCTURES TAKING SHAPE AT TOLUKUMA GOLD MINE
Tolukuma Gold Mine ("TGM") is a mining operation based in Papua New Guinea.
TGM is owned by Emperor Mines Limited, a company registered in Australia and
listed on the Australian Stock Exchange in which DRDGOLD hold 79.7% through
its wholly owned subsidiary DRD (Offshore) Limited, a company registered in
the Isle of Man.
Exploration development and underground diamond drilling at TGM has continued
to intersect high grade gold mineralisation on the Zine Structure as well as
in a newly discovered splay off the Zine structure. The Zine Structure is now
being developed in two drives on the 1525m RL and 1495m RL levels
respectively. To date more than 140m of strike length of the Zine Structure
has intersected high grade mineralisation on 1525m level and 30m of strike
length on 1495m level. An exploration drive along the new Zine Splay
structure has intersected 97 m of mineralised strike length. The sampling
results from this development are shown below.

A significant feature has been the discovery of the above mentioned
mineralised splay structure off the main Zine vein structure, trending in a
south easterly direction. This discovery is very significant being the first
high grade mineralised vein to be found extending eastwards from the known
vein array that has been mined at Tolukuma. It indicates the potential for an
entirely new mineralised corridor to the east, as well as a new internal
target area along the potential north west extension.
Zone 1 on 1495 level and Zone 2 on 1525 level both remain open to the south
whilst the newly discovered splay vein is open to the south east. Diamond
drilling has also intersected the Zine vein some 100m south of current
development in hole TU071 and some 160m down dip in hole TU073 both of which
returned similar styles of mineralisation.
The following table lists the underground diamond drilling results from the
main Zine and Zine Splay structures.

TU075 1.6m @ 13.8 g/t Au and 40.1 g/t Ag 60 1419
Due to the exceptionally soft and clay rich nature of the Zine ore body, and
the possibility of high water pressures encountered in the Zine vein, drill
results to date are affected significantly by poor core recovery. This
commonly results in the reported drill intersection significantly under
calling the actual mineralisation intersected by exploration development.
Similar to many other high grade ore bodies it is often a case of "drill for
structure, drive for grade."
The continued success of the underground development and diamond drilling
exploration is confirmation that the Zine mineralised vein structure and
associated splay are likely to host a significant high grade, low
sulphidation ore body. Of particular importance is the close proximity of
these discoveries to existing mine infrastructure which will allow their
speedy incorporation into the mining plan. Development has commenced on 4
levels and it is anticipated that the mineralised structure will contribute
to production in the December 06 quarter.
Currently two underground rigs are conducting step out drilling whilst a 3rd
rig is being shipped to the mine to expedite the resource infill drill
program.
