Grange Exploration Target
The primary target of the proposed drill program is the previously announced Grange Exploration Target, which is situated within the Tatyoon exploration licence, on the western flank of the Grange basalt dome (see Figure 3). The potential quantity and grade of the Grange Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource, and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
The Grange Exploration Target is a Stawell-style gold exploration target identified by Navarre following the compilation of geology and geophysical research undertaken by Navarre. The target is approximately 1,500 metres in length and is located at shallow depths from approximately 35m to 350m (vertical depth) below surface (see Figure 4). Using the analogy of Stawell’s Magdala gold deposit as a predictive model, in particular the attributes of Stawell’s Central Lode orebody (average thickness of about 5m), the Company’s Competent Person has estimated the Exploration Target for the western flank of the Grange basalt dome of between approximately 6 to 10 million tonnes with gold grade of between approximately 4 g/t Au and 6 g/t Au (approximately 0.8 to 1.9 million ounces of contained gold; Table 1). It should be noted that the Grange Exploration Target is conceptual in nature as it is not based upon existing drill data and, as yet, has not been drill tested.

Figure 3: Perspective view locating the Grange Exploration Target with respect to geophysical sections and previous drilling. Yellow targets are interpreted as ‘Waterloo’-style structures familiar to the Stawell Gold Mine (see Figure 5). Exploration Targets are conceptual in nature and there is insufficient information to establish if further exploration will result in the determination of a Mineral Resource. The Grange Exploration Target is conceptual and is not based upon any existing drill data.
In accordance with clause 17 of the JORC Code (2012 edition), the following background information supports the Exploration Target which was stated in the Company’s Quarterly Activities Report dated 21 January 2015, and remains unchanged.
Background – Stawell Corridor Gold Project:
Navarre’s Stawell Corridor Gold Project, incorporating a 2004 discovery of gold under-cover at Tatyoon and the historic Ararat Goldfield, is located between 10 and 70 kilometres south-east of the operating Stawell Gold Mine which is owned by Navarre’s largest shareholder and leading Victorian gold producer, Crocodile Gold Corp.
Ninety percent of the prospective Stawell Corridor lies buried beneath shallow cover, only to surface between Stawell and Ararat where approximately 6 million ounces of gold has been historically mined (Figures 1 & 2).
Gold mineralisation of the Stawell-type is located on the flanks of large basalt dome structures. The style of the gold mineralisation is much finer grained, more continuous and more predictable than the gold deposits typically found at Victoria’s largest two goldfields at Bendigo and Ballarat.
Work conducted at Tatyoon before grant of Exploration Licence to Navarre
In 2004 previous explorer, Leviathan Resources Limited (“Leviathan”) made a gold discovery at Grange Road, Tatyoon, in the last hole of a 21 air-core drill program. Aircore drill hole AAC021 pierced through a 30m thickness of Newer Volcanics cover to intersect 5 metres at 1.4 grams per tonne of gold (starting at 35m) from within an interval of 20 metres at 0.5 grams per tonne of gold (starting from 30m depth; Figure 4). A further higher grade gold intercept of 2 metres at 2.6 grams per tonne of gold was also reported from 66m near the base of the hole.
Discovery drill hole AAC021 highlighted the gold potential of the Grange basalt dome target and together with other drill holes into the weathered basement have confirmed the main geological elements for potential Stawell-style mineralisation at Tatyoon.
ASX Announcement 19 March 2015 – Completion of Capital Raising & Exploration Update - Stawell Corridor Gold Project
In 2005 Leviathan conducted a follow-up drill program, which resulted in diamond hole TTD001 being drilled beneath AAC021, intersecting 1.8 metres at 4.2 grams per tonne of gold from 91.4m. This was the length-weighted average of the 3 fire assay analyses for each of the 2 samples comprising the 1.8m interval and included a maximum grade of 0.8 metres at 8.3 grams per tonne of gold from 92.4m (see Appendix 1; Tatyoon Historical Exploration Results). The gold mineralisation is hosted within strongly altered sulphide-rich sediments which inter-finger with the basalt (historically referred to in the Stawell Goldfield as ‘Waterloo’ structures) on the top of the basalt dome structure (see Figures 3 & 6).
Subsequent drilling of two further diamond holes was undertaken by Leviathan in 2005, one beneath TTD001 and another approximately 350m on-strike to the south. Both drill holes intersected altered and highly sulphide-rich sediments within a ‘Waterloo’ structure but with lesser gold contents than previous drilling. No previous drilling has been undertaken on the western flank of the Grange basalt dome .

The diagram also shows the location of the northern end of the conceptual Grange Exploration Target. The potential quantity and grade of the Grange Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
Since 2006 no further exploration drilling has been undertaken at Tatyoon and the licence was allowed to expire. A new exploration licence (EL 5480) was granted to Navarre for a period of 5 years in September 2014.
Work conducted by Navarre at Tatyoon
Recently after grant of EL 5480, the Company completed a compilation and assessment of historical exploration data, including re-processing and modelling of all existing geophysical surveys across the Tatyoon area.
ASX Announcement 19 March 2015 – Completion of Capital Raising & Exploration Update - Stawell Corridor Gold Project
Gravity Geophysics
Navarre generated a geologically-constrained model of the existing gravity data using geological information collected from existing drill holes and rock density information from similar rocks within the Magdala Gold Mine at Stawell. This defined a cluster of three shallow basalt dome structures in the centre of the Tatyoon tenement (see Figure 5 below). A study of the new Tatyoon gravity model indicates that the Grange basalt dome is similar in size and shape to the Magdala basalt dome that controls the long-life, multi-million ounce Magdala gold deposit at Stawell. Furthermore, the sparse drilling of 2005 shows the gold mineralisation starts at approximately 30m from surface, offering a shallow target.
All three historic Grange prospect diamond drill cores have been recovered, examined and confirm Navarre’s understanding of the subsurface geology.

Induced Polarisation Geophysics
Navarre re-processed raw data from existing Induced Polarisation (“IP”) geophysical surveys, originally collected over several programs between 2005 and 2011, to generate inversion sections representative of the electrical properties of the subsurface geology. IP is an electrical technique commonly used to detect disseminated sulphides below the surface which are usually recorded as areas of high and low electrical chargeability. Stawell-style gold mineralisation has a strong association with sulphide minerals such as pyrite, pyrrhotite and arsenopyrite which are usually represented as IP high chargeability zones.
ASX Announcement 19 March 2015 – Completion of Capital Raising & Exploration Update - Stawell Corridor Gold Project
The results of Navarre’s work show:
-
The presence of 4 consecutive high chargeability anomalies occurring in similar positions on four of the five IP sections across the Grange basalt dome. Correlation of these IP anomalies with the independently derived gravity model reveals an approximately 1,500 metre long target coincident with the western flank of the Grange basalt dome (see Figures 3 & 6).
-
The existence of three other high chargeability anomalies interpreted to represent potential ‘Waterloo’ surfaces on the top of the Grange basalt dome (Figures 3 & 6). One of these ‘Waterloo’ structures detected in the IP geophysics is confirmed by previous drilling to have sulphide-bearing sediments containing gold (see TTD002 in Figure 9).
-
Potential IP chargeability anomalies also occur in some areas of the adjacent Hermitage basalt dome. These anomalies are less certain than at Grange due to potential electrical interference from fences intersected in the IP survey lines. Further data validation will be required.

Basis for the Grange Exploration Target
The Grange Exploration Target at Tatyoon was estimated using historic data that was collected by Leviathan during 2004 – 2011. Data generated during this period included gravity surveys, IP geophysics, scout air-core drilling and three diamond drill holes. As outlined above, Navarre has compiled this information, reviewed the diamond drill core, reprocessed the geophysics and undertaken an interpretation of the geology guided by Stawell’s Magdala Gold deposit as its predictive model.
The Grange Exploration Target is a geophysical target of approximately 1,500m length comprising 4 evenly spaced IP chargeability highs that align along the western flank of the Grange basalt dome as determined from the gravity model. Although the Exploration Target does not contain any drill information, existing 2005 diamond drill data (130m east of
ASX Announcement 19 March 2015 – Completion of Capital Raising & Exploration Update - Stawell Corridor Gold Project
the target) supports the gravity model in geological architecture and the possibility that IP chargeability anomalies within the Exploration Target are the result of sulphide-rich sediments which may be gold bearing (see Figures 3 & 4).
The general slope of the western flank sediment–basalt contact, where the IP chargeability anomalies occur, is derived from Navarre’s gravity model. The shape of the Exploration Target is conceptualised as being a folded lobe of basalt similar to Stawell’s Magdala Mine’s west flank and is supported by the irregular geometry of several of the Grange IP chargeability anomalies (see Figures 6 & 7).
Estimation of grade and tonnage ranges for the Grange Exploration Target
The volume of possible gold mineralisation contained within the Exploration Target was generated with wire-framing methods using three-dimensional Micromine mine planning software. The wireframe model was constructed by digitising a series of polygons, at regular intervals, perpendicular to the strike of the western dome basalt-sediment contact where the IP chargeability anomalies occur.
As is the case at Magdala, the digitised polygons have a “folded” shape to account for the extra prospective sedimentbasalt contact areas due to repetition caused by basalt-sediment inter-fingering (see Figure 7).
The polygon shapes were tapered at the models extremities, while being thicker in roll-over positions around basalt “noses” representing potential stockwork vein zones typically seen in the Magdala deposit (see Figure 7). These polygons were then linked together to form a valid wireframe solid that was used to derive a volume.

The potential quantity and grade of the Grange Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
ASX Announcement 19 March 2015 – Completion of Capital Raising & Exploration Update - Stawell Corridor Gold Project
The key factors used to develop the tonnage estimates were:
-
The true thickness of gold mineralisation used in the construction of the wireframe 3D model is assumed to vary between 3m and 5m corresponding with typical thickness ranges for Magdala’s Central Lode deposit;
-
The approximate 1,500m strike length is open to the south but is restricted by the dome margin in that direction. It is modelled to a tapered termination close to the Grange road section where the IP response is of low confidence owing to potential interference from steel fences bordering the road (see Figure 3); and
-
The specific gravity is based on the Stawell-style sulphide-rich mineralisation of 2.85 + 0.15 t/m[3] (Big Hill bulk density physical tests sourced from; Crocodile Gold Corporation NI 43-101 Technical Report – Big Hill Enhanced Development Project at Stawell Gold Mine–Mineral Resources & Reserves, 6 June 2014).
These factors resulted in a tonnage range estimate of between approximately 17.9Mt and 19.9Mt from the modelled volume (see Table 1).
The following factors were then applied to arrive at the final Grange Exploration Target estimate:
-
Study of stope distribution within Stawell’s Magdala Mine indicates 33% to 50% of the total mineralised surface area along the western flank is generally economic. It was decided to discount the estimated tonnage ranges by these payability factors; and
-
The average historical mineral resource gold grades mined from within ore reserves of Stawell’s Magdala mine is between 4 and 6 g/t Au. These grades are consistent with recent exploration intersections announced by Stawell Gold Mine owners Crocodile Gold Corp. (TSX:CRK) on 19 February 2015 and historical Stawell mine gold grades for the Central Lode. This grade range is assumed possible for the Grange Exploration Target.
From these constraints a Grange Exploration Target tonnage range of between approximately 6Mt and 10Mt at a gold grade of between approximately 4 g/t Au and 6 g/t Au for approximately 800,000 to 1,900,000 ounces of contained gold mineralisation is estimated (see Table 1). Please note this Exploration Target is conceptual in nature and there is insufficient information to establish whether further exploration will result in the determination of a Mineral Resource. It is also noted that this Exploration Target is conceptual and is not based upon any existing drill data.
Further evidence supporting the Grange Exploration Target is:
-
The estimated dimensions of the Grange basalt dome are similar to the producing Magdala Mine basalt dome at Stawell;
-
80% of the gold produced from the Magdala Mine was derived from the western flank of the Magdala Basalt dome. Similarly, the largest geophysical target at Grange is located on the western flank of the basalt dome; and
-
Alteration and mineralisation styles observed in Grange diamond core are similar to Stawell’s Magdala mine with high arsenopyrite-pyrite contents and pervasive chlorite-silica alteration.
Planned drilling program to test the Grange Exploration Target
As mentioned above, Navarre expects to commence, an RC and diamond drilling program of up to 2,000m at its Grange prospect in late March. The following diagrams (Figures 8 & 9) provide a visual representation of the proposed drill program.

About Navarre Minerals Limited:
Navarre Minerals Limited (ASX: NML) is an Australian-based resources company that is creating value from a portfolio of early to advanced stage gold and copper projects in Victoria, Australia. Navarre’s aim is to discover and develop large low-cost copper and gold production through its exploration successes.
Navarre is searching for new long-life gold deposits in the partially covered extension of a corridor of rocks that host the Stawell (~5 million ounce) and Ararat (~1 million ounce) gold deposits. The exciting Tatyoon discovery is the Company’s prime focus for early 2015, located 50km south-east of the operating Stawell Gold Mine which is owned by Navarre’s largest shareholder and leading Victorian gold producer, Crocodile Gold Corp.
The Company is also targeting large porphyry- copper, VMS and gold deposits. The Eclipse, Lexington, Pollockdale and Glenlyle prospects are four initial porphyry and/ or VMS targets identified within the Western Victoria Copper Project. The Project captures multiple, largely untested targets in 130km of western Victoria’s newly uncovered Miga Arc volcanics. The Miga Arc is similar in setting to the Andes in South America, host to the world’s largest known collection of porphyry copper deposits. Grassroots exploration of the Company’s extensive exploration permits is at an early stage and more than 50 new targets remain to be thoroughly drill tested.
At the high-grade Tandarra prospect within the North Bendigo Goldfield of central Victoria, exploration work is targeting the next generation of gold deposits under shallow cover 40kms north of the 22 million ounce Bendigo Goldfield. Under a farm-out agreement, Catalyst Metals Limited is earning a 51% equity interest in Tandarra by spending $3 million over four years by advancing the project towards mineral resource status.
Navarre has a highly experienced leadership team with 120 combined years of exploration, mining and finance industry experience with a proven track-record of discovery and project development.

| Tenement and land tenure |
The Grange prospect lies within Navarre’s 100% owned exploration licence EL 5480 which was granted on 9 September 2014 for 5 years. Theprospect occurspredominantlyacross freeholdpastoral land and lesserpublic road reserves. |
| Exploration done by other parties |
The exploration results reported are wholly from activities conducted by SGM since 2004. Initial works was done by SGM owners MPI under a farm-in to licence EL 4695 then held by Reliance Mining Ltd. Following de-merger of MPI resulting in ASX float of Leviathan Resource Ltd in late 2004 the licence was purchased by Northgate Australian Ventures (now owner of SGM following 2 successive corporate takeovers). In 2008 Northgate offered Rimfire Australia PL a partnership option to explore EL 4695 at Tatyoon and surrounds which ended in 2012 and the previous licence was allowed to expire in April 2013. SGM and Rimfire conducted a series of gravity surveys and IP geophysical lines across basalt targets including Tatyoon, Langi Logan and Westmere now held 100% by Navarre Minerals. This data has recently been utilised by Navarre to model the location of IP anomalies and gold in drilling relative to the basement basalt dome at Grange and Hermitage prospects. Further open file information concerning the exploration upon EL 4695 can be found with the Victorian Geological Survey. |
| Geology | The project area is considered highly prospective for the discovery of economic deposits of similar character to the deposits in the nearby Stawell gold mine, particularly the Magdala gold deposit. The Stawell Goldfield has produced approximately 5 million ounces of gold from all sources and more than 2.3 million ounces from underground and open pit sources during the modern mining era across more than 3 decades. Drilling intersects thin Newer Volcanics (28 to 66m), quartz gravels, clay and thin coal beds, then saprolitic to fresh Palaeozoic bedrock. The northern (and probably eastern) margin of the basalt dome is in close contact to the Ararat Granite. |
| Drill hole Information |
A summary of drill hole information is provided in the above Table of significant results. All holes at Tatyoon are listed in Table 1. All exploration drill assays reported are expressed as downhole intervals. Diamond holes were collared as follows Hole Dip GDA_Azimuth TTD001 -55 99.5 TTD002 -58.5 99.8 assumed same as 30m dhole survey TTD003 -61.7 90.3 assumed same as 30m dhole survey A single deep diamond hole was drilled into the Hermitage dome in 1983 by Australian Anglo- American (AA5 668947.2m GDA_E, 5848927.4m GDA_N, 256.76m RL, -60otowards 081oGDA94). Geology logs for this 265.5m deep hole are scant and describe the basement rock intersected as “amphibolite” suggesting a possible higher metamorphic grade than known from diamond core at Grange. Disseminated sulphides are recorded from 60m downhole and anomalous copper grades to 0.2% Cu and silver grades to 33 ppm Ag. These results have not been verified. Two other historical RC percussion holes are recorded being drilled near the Hermitage dome, however, their location is poorly recorded and no lithological logs exist. No significant assays are reported. |
| Data aggregation |
Significant gold intercepts are calculated using a 0.1g/t Au cut off for diamond drill results and 15ppb Au for aircore results. No topcuts are used |
| Mineralisation relationship |
The relationship between mineralisation widths and intercept grades is not known due to insufficient diamond drill information to define thegeometryof mineralised structures. |
| Balanced reporting |
Comprehensive reporting has been undertaken with both mineralised and unmineralised holes/samples listed in attached tables and figures. All existingdrill holes at Grange and Hermitage are reported. |
| Further work | This western flank will be the main target for RC and diamond drilling on each IP section in the upcoming drill program. Maximum depths to be tested are likely to be 350m with most holes being 120m or less in total depth. |
