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

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

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

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

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

15m @ 0.7% Cu, 1.9% Zn, 0.8g Au/t (RC92GM52)
13m @ 0.7% Cu, 0.2g Au/t, inc. 2m @ 2.2% Cu (RC92GM55)
2.0m @ 3.0% Cu, 2.0g Au/t (RC93GM65)
