Unicorn Project - RESOURCE DRILLING TO COMMENCE

Dart Mining is pleased to announce it has secured a diamond drilling contractor to carry out a round the clock program commencing in early May 2011. The Resource drilling program will define the initial potential of the Unicorn Molybdenum – Copper – Silver porphyry system. This program is the next step towards the estimation of a maiden resource for the Unicorn porphyry in what the company considers a project of world class potential.

UNICORN RESOURCE DRILLING PROGRAM

Dart Plans to carry out a series of deep diamond drill holes of up to 800m in length to establish the size and grade of Mo – Cu – Ag mineralisation associated with the Unicorn Porphyry.

Key Projects / Metals

• Unicorn Porphyry Mo-Cu-Ag

• Morgan Porphyry Mo-Ag-Au

• Mountain View Lode – Au

Mo – Molybdenum Cu – Copper Au – Gold Ag – Silver

The first drill hole will test an interpreted continuation of the M1 mineralisation below outcropping zones of silica alteration radiating NW from the main Silica Cap (Figure 1). This hole also aims to define the northern extent of the intrusive system and further test the previously reported M2 mineralised horizon below a second silica cap (intersected in hole DUNDD004A). This hole will determine the final design of the Resource program drill sections.

Initial Resource drilling is planned on a series of 100m spaced sections (Figure 1) with a fan of east-west drill holes at each location.

Background.

Previous work has shown the Unicorn Mo – Cu – Ag mineralisation is associated with a large multipulse rhyolite / quartz feldspar porphyry intrusive system with overlapping phases of molybdenum, copper and silver mineralisation throughout. It has many characteristics similar to the giant Henderson and Climax molybdenum mines in Colorado, USA. Climax style deposits form the largest primary molybdenum deposits worldwide.

ABOUT MOLYBDENUM

Molybdenum is a strategic metal, when added to steel it enhances strength, hardness, 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 from approximately 210,000 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 times the price of copper which recently hit a record high of USD10,000/tonne. Silver has reached new 30-year price highs exceeding USD44/oz (1oz Silver = 31.1grams).
