The contents of this presentation must not be photocopied, reproduced, disclosed or distributed to any other person without the prior written consent of Navarre. The information in this presentation that relates to Exploration Results, Mineral Resources and Exploration Potential is based on information compiled by Mr Wessley Edgar. Mr Edgar is an employee of Navarre Minerals Limited, is a member of the Australasian Institute of Mining and Metallurgy and is a Competent Person under the definition of the 2012 JORC Code. The Exploration Potential described in this Presentation is conceptual in nature, and there is insufficient information to establish whether further exploration will result in the determination of a Mineral Resource. Mr Edgar consents to the publication of this information in the form and content in which it appears. The information in this presentation that relates to exploration and production targets refers to targets that are conceptual in nature, where there has been insufficient exploration to define a Mineral Resource and it is uncertain if further exploration will result in the determination of a Mineral Resource. The information on porphyry copper and gold exploration targets in this presentation are based on a conceptual range of targets as follows: Tonnage range: 300 million to >500 million tonnes Grade range: 0.3% Cu to 2.0% Cu & 0.2 g/t Au to 2 g/t Au Metal: 1Mt contained copper & >0.5 million ounces of gold ASX Code: NML 2 of 22

Western Victoria Copper Project Multiple, largely untested targets in 130kms of volcanic rocks Tenements Black Range Copper (Cu), Gold (Au) EL4590 and EL5426 Stavely Copper (Cu), Gold (Au) EL5425 Mitre Copper (Cu), Gold (Au) EL4973 Mineralisation Style Bulk tonnage porphyry copper (Cu) and gold (Au), VHMS (Cu, Pb, Zn, Au), epithermal base metals & gold Deposit Analogues Cadia, Pebble, Grasberg, Mt Lyell 6 of 22
  7. 7. Eclipse New geological thinking leads to recognition of porphyry PREVIOUS EXPLORATION & TARGETING WAS BASED ON A VHMS MODEL  Eclipse geology similar to Mt Read Volcanics of NW Tasmania, host to Mt Lyell and several VHMS deposits such as Rosebery & Hellyer  276.1m @ 0.3% Zn & 0.1g Au/t in DD10BR001 from 1.3m depth to end of hole originally interpreted to be footwall alteration to VHMS system (see 2010 model below) NEW PORPHYRY MODEL BETTER FITS GEOLOGY  Demagnetised geophysical feature co-incident with gravity low & anomalous base metal geochemistry  Massive zone of zinc mineralisation in DD10BR001 is common feature in margins of porphyry copper-gold deposits  Search for mineralisation on west-side of DD10BR001  Porphyry case studies reveal optimum method for detecting buried deposits Copper-rich drill core from DD10BR001 7 of 22
  8. 8. What is a porphyry?  Porphyry copper deposits are large, relatively low-grade, intrusion-related deposits that can be mined using mass mining techniques  Typical economic porphyry deposits have reserves of between 500Mt & several billion tonnes of 0.3 - 2% copper & 0.2 – 2 g/t gold  Porphyry copper deposits are usually associated with gold and/or molybdenum 8 of 22

  10. 10.  Miga Arc speculated to be a subduction-related Andean-style magmatic arc related to the younger Macquarie Arc of central NSW  Miga Arc similar to Mt Read Volcanics based on age & rock type  Miga Arc is dominantly concealed below thin cover and remains under-explored – no deep drill holes  Magmatic arc systems are highly prospective for porphyry copper, VHMS & epithermal-style base metal and gold deposits, eg. Cadia, North Parkes Fore-arc subduction complex Miga Arc – cross-section, after Cayley et al, 2011 Miga Arc Victoria’s new emerging copper belt 10 of 22
  11. 11. Western Victoria Copper Project - Miga Arc Under-explored volcanic province containing large porphyry Cu-Au targets  130 kms of under-explored pacific rim style volcanic belt with no deep drill holes  Near established infrastructure (power, port, rail, highways, workforce & processing facility)  Porphyry-style copper mineralisation confirmed by drilling at Eclipse and Lexington prospects  >276 m of zinc + gold + pyrite hydrothermal alteration in DD10BR001 indicates proximity to porphyry core at Eclipse  Sole diamond hole at Lexington intersects primary copper up to 0.6% and Mo up to 800ppm in altered granodiorite host of Cambrian age  Navarre activities completed:  26 drill holes for 2,200m at Eclipse  Detailed aeromagnetic survey at Eclipse  Soils geochemistry, EM & IP geophysics surveys on Eclipse  Review of recently uncovered historic data for Lexington  Reconnaissance mapping, rock chip & soils at Lexington  50 targets developed for follow-up 11 of 22
