REPORT FOR THE QUARTER ENDED 31 DECEMBER 2010
HIGHLIGHTS
-
Diamond drill hole, DUNDD006, completed. The hole was mineralised from surface to the end of hole at 488.4m and intersected several zones of higher grade mineralisation.
-
This completes the initial wide spaced drilling program with all holes mineralised throughout with several higher grade zones of combined Mo-Cu-Ag.
-
Unicorn’s 3D induced polarisation (IP) geophysical survey modelling was completed this quarter. It revealed a large conductivity anomaly with an inverted trumpet shaped core expanding beneath the silica cap outcrop.
-
Dart completed a $1million placement on 9 Dec 2010 and announced a 1 for 3 rights issue to shareholders. The Issue which closes at 5:00pm on 1 February 2011 is priced at 6.5 cents. For every 2 rights taken up, Dart will issue one option which may be exercised at 10 cents a share on or before 31 December 2011.
UNICORN DRILLING AND GEOLOGY
At the Unicorn project, located near the town of Corryong in north-east Victoria, the third deep diamond drill hole DUNDD006 was completed. This concludes the Phase II program supported by a State Government grant of $80,000 (the maximum amount) awarded in Round 3 of the Rediscover Victoria Drilling program. All assays from the program have now been received.
The program included drillholes DUNDD004, 4A and 5, drilled on E-W section 8100mN. DUNDD006 was collared 80 metres to the south and aimed to the south-west to test a breccia zone on the south-west boundary of the Unicorn Mo-Cu-Ag system for evidence stronger mineralisation at depth. Results were reported to ASX on 17 January 2011. The hole was mineralised from surface to the end of hole at 488.4m and intersected multiple zones of high grade silver mineralisation. Results include:
488.4m @ 0.03 % Mo; 0.04% Cu and 4.28 g/t Ag including:
64m @ 0.06% Mo from surface;
132m @ 0.08% Cu from 24 metres; 30m @ 9.5g/t Ag from 124 metres; 6m @ 28.2g/t Ag from 393 metres; and
52m @ 9.7g/t Ag from 434 metres.

Geological mapping at Unicorn is ongoing. Work this quarter has identified a silica outcrop zone, with evidence of mineralisation, radiating north-west from the central silica core to at least 8400m N.
Modelling of the 3D Induced Polarisation (3D IP) survey was completed. The results show a large chargeability anomaly with an inverted trumpet shaped core expanding beneath the silica cap outcrop with perimeter conductors open at depth. This model is assisting resource drill targeting.

INTERPRETATION OF RESULTS
Unicorn’s surface footprint, is of similar size to the giant Henderson and Climax mines in Colorado, USA. Significantly Climax style deposits form the largest molybdenum deposit worldwide. Unicorn is considered to be the first Climax style molybdenum porphyry discovered in Australia but differs to typical Climax systems in having significant additional copper and silver due to its geological setting.
The widely spaced drilling of the Phase II program intersected significant molybdenum copper and silver mineralisation to a depth of 578 m down hole, Geological modelling confirms Unicorn is a large porphyry intrusion mineralised throughout with overlapping multiple pulses of sub horizontal higher grade mineralisation. The host rocks are interpreted as very high in the original mineral system and point to an increasing size of the Unicorn Mo-Cu-Ag porphyry system with depth. The 3D IP results show a large chargeability anomaly (red) ridging out to the north-west of DUNDD004 that has not been tested by drilling to date The anomaly has an inverted trumpet like geometry below the silica

cap supporting the interpretation that the mineralised system grows with depth. It is considered significant that mineralisation intersected to date is outside this anomaly.
REGIONAL EXPLORATION
Exploration on Darts large strategic tenement position in north-east Victoria continued through the quarter with a number of intrusions identified as potentially mineralised porphyries. Soil sampling grids are being established with the first over the Boebuck prospect. This appears to be a buried intrusive mineralisation zone within a prominent magnetic ringed geophysical anomaly some 3km in diameter. Topographic and geophysical modelling has also identified the Bunroy prospect which will be sampled.
PLACEMENT AND RIGHTS ISSUE
Dart completed a $1million placement on 9 Dec 2010 and announced a 1 for 3 rights issue to shareholders. The Issue which closes on 1 February 2011 is priced at 6.5 cents. For every 2 rights taken up, Dart will issue one option which may be exercised at 10 cents a share on or before 31 December 2011.
ABOUT MOLYBDENUM
Molybdenum is a strategic metal, when added to steel it enhances strength, hardenability, weldability, toughness, elevated temperature strength, and corrosion resistance. In nickel-base alloys, it improves resistance to both corrosion and high-temperature creep deformation. Molybdenum has a range of chemical uses including in paints, plastics and catalysts, it is also an essential trace element in humans, animals and plants.
The world market for molybdenum is growing with approximately 200,000 tonnes a year and the metal has been traded on the London Metal Exchange since February 2010. At recent prices molybdenum trades at approximately 4.5 times the price of copper.
