FURTHER HIGH GRADE MOLYBDENUM AT UNICORN

HIGHLIGHTS
High Grade Molybdenum (29m @ 0.11% Mo) Intersected within Porphyritic Rhyolite
Open Broad Copper Mineralisation in quartz stockwork (130m @ 0.11% Cu)
Strong Silver mineralisation (130m @ 7.3 ppm Ag)

UNICORN PROSPECT

Additional assay data from drill hole DUNDD004 (Figures 1 & 2) has been received. The
previously reported interval (ASX announcement 12 May 2010) of stockwork porphyry from 89.5m
has now been extended and confirms the association of molybdenum with copper and silver within
intense sericitic alteration. The copper exhibits good consistency, the molybdenum is exhibiting
some nugget effect typical of deposits of this type.
The results so far represent just a tiny proportion of the very large Unicorn rhyolite porphyry dome.
The recognition of multi-directional quartz veining and continuous visible molybdenum
mineralisation hosted in multiple and overprinting highly altered rocks, with distinct similarities to
the Climax and Henderson mines in Colorado USA, is of real significance.
Further assay data will be reported as it comes to hand. A minimum of one additional hole is
planned on this section to reconcile geochemistry, structure, alteration, and geophysics datasets
within the context of this very large mineralised system (Figure 2). Further drilling toward a
resource estimate will then be planned.
The Phase 2 Diamond Drilling Program is supported by a State Government grant of $80,000 (the
maximum amount) awarded in Round 3 of the Rediscover Victoria Drilling program.
DUNDD004
Further high grade Molybdenum (Mo) has been returned in assay results from surface to 130m in
drill hole DUNDD004 (Figures 1 & 2). Dart considers the high grade molybdenite mineralisation
developed in quartz stockwork (29m @ 0.11% Mo Table 1) represents primary hydrothermal
mineralisation which also contains significant copper (130m @ 0.11% Cu) and silver (130m @ 7.3
ppm Ag) see Appendix 1 for assay listing.
The Rhyolite Dome model (Figure 2) applied to the Unicorn System remains valid and is showing
various styles of alteration, the most extensive being silica and sericite bleaching, typical of distal
alteration. This is further illustrated by small zones of silica epidote chlorite (lower temperature
alteration) intersected to date.

DUNDD004A
DUNDD004A started as a new hole at a depth of 154m in DUNDD004 and is currently at a depth of
360m. DUNDD004 was terminated at a depth of 321.9m following bit failure in strongly faulted
ground. DUNDD004A is being drilled in the larger HQ hole size and has allowed penetration of the
fault at 320m prior to reducing to NQ. The large fault at this level appears to correspond to the top
of a second silica cap zone. This may indicate the presence of further porphyry phases (Figure 2).
Drilling is now progressing well within mineralised porphyry showing significant visible molybdenite
to current hole depth of 360m.
The new hole duplicates DUNDD004 from 154m to a depth of 321m and provides an excellent
opportunity to investigate the impact core size has on assay data and vein frequency / orientation.
The additional core will also enable a start on metallurgical testing.
DUNDD004A has already indicated a higher frequency of very high grade radial veins that run
nearly parallel to the original hole but cross cut the current hole orientation (which is near eastwest)
