Results reinforce Navarre’s confidence for the Irvine Gold Project to potentially host a significant gold system similar to the 4Moz Magdala gold deposit
Navarre Minerals Limited ( Navarre or the Company; ASX: NML ) is pleased to announce further significant, shallow gold intersections from its current phase of drilling at its highly prospective 100%-owned Irvine Gold Project, located 15 kilometres south of Stawell in western Victoria (Figure 1).
The results are from the final batch of assays received for the remaining 23 holes (holes IAC343 – IAC365) of a 54 hole air-core (AC) drilling program totalling approximately 3,200m at the Adventure Lode discovery and the Dutton prospect, within the Irvine Gold Project. The latest results complement those of the first 31 AC holes previously reported to the ASX on 1 May 2018.
Drilling at the Adventure Lode has been highly successful. All 16 AC drill traverses recently completed have intersected the main quartz structure resulting in the definition of a higher-grade zone of gold mineralisation, approximately 800m in length and similar in style to the orebody geometries of the nearby 4Moz Magdala gold deposit at Stawell.

Figure 1: Location map of Navarre’s Irvine Gold Project. Navarre has 70 kilometres of strike of the prospective Stawell Corridor under exploration licence.
The latest results, reported in this announcement, confirm the continuity of strong gold mineralisation at the Irvine Project and continue to enhance the Project’s potential to host a major new gold system.
Planning for a 3,000m program of resource definition reverse circulation (RC) drilling is underway and is scheduled to commence in late May 2018 to extend the Adventure Lode at depth to approximately 120m below surface (Figure 4).
Assays for four diamond core holes completed at the Resolution Lode discovery within the Irvine Project will be reported to the market following receipt and geological interpretation.
The Company’s infill and expansion AC drilling at the Irvine Project is testing the surface oxide to transitional horizons. Drilling at the Adventure Lode was designed to locate the presence of higher grade gold shoots within the 1.2km long Adventure Lode, along the flanks of the Irvine basalt dome akin to the Magdala gold deposit. Infill drilling at the Adventure Lode has successfully followed-up shallow high grade gold intersections (of up to 6m @ 5.1 g/t gold) from Navarre’s previous AC program.
Adventure Lode drilling results
The Adventure Lode is located on the east flank of the Irvine basalt dome in the same geological position as the Resolution Lode located 4 kilometres to the north (Figure 2).
Sixteen drill traverses comprising 47 infill holes for 2,720m of drilling at nominal north-south spacings of between 50 and 100 metres have been completed across the 1.2km long Adventure Lode quartz structure (Figure 2). All drill traverses intersected the quartz structure with drilling defining a higher-grade zone of gold mineralisation.

The results continue to confirm the continuity of potential ore grade gold mineralisation hosted within a broad shear zone containing abundant quartz. The AC drilling has defined a strong zone of shallow gold mineralisation (>1 g/t Au) occurring from surface and extending over 1.2 kilometres in strike. The mineralisation remains open down-dip to the west where the gold tenor is expected to increase below the oxide zone in a pattern similar to that occurring at the Resolution Lode and at the Magdala gold deposit.
Each drill traverse in the current program intersected the same gold-bearing shear zone which is interpreted to dip between 40 and 60 degrees towards the west (Figure 5). It is estimated that most drill intercepts are close to true width, as drilling is generally angled at 60 degrees to the interpreted structure. The shear zone is up to 30 metres wide.

Dutton Prospect
The Dutton prospect is located on the east flank of the Irvine basalt immediately south of Adventure Lode (Figure 2). Previous wide-spaced reconnaissance AC drilling by Navarre in 2017 has highlighted the potential for ore-grade gold mineralisation at Dutton.
Significant results previously reported to the ASX on 24 January 2018 include:
-
6m @ 1.6 g/t Au from 30m, including 1m @ 5.3 g/t Au from 31m in IAC291
-
3m @ 1.2 g/t Au from 4m in IAC292
The style and dip of the mineralisation is believed to be similar to Adventure Lode.
In March 2018 the Company drilled two, 200m spaced, expansion AC drill traverses totalling 7 holes for 503m off the southern end of the prospect (Drill Traverse D4 and D5 shown on Figure 2). No significant intercepts were returned from this phase of drilling. Focus now shifts to the central and northern areas of the Dutton prospect where the Company is awaiting regulatory approval of a work plan to undertake drilling.
In the meantime, reconnaissance AC drilling is planned to test for additional gold mineralisation up to 1 km further south of Dutton following a positive mapping and surface rock chip sampling program. This drilling is planned to follow completion of the St Arnaud program which is expected to conclude in 2 weeks.
Next Steps
The Company is presently planning a resource definition RC drilling program for Adventure Lode. All significant intercepts are expected to be followed-up with infill or deeper RC drilling. Subject to results, Navarre believes the resource definition drilling program has the potential to lead to a maiden mineral resource for the Irvine Gold Project.
The Company also plans a further AC drilling program for the central and northern areas of Dutton and a potential extension 1 km further south following positive mapping and rock chip sampling results from earlier in 2018.
Navarre believes the multiple zones of gold mineralisation it has discovered at the Irvine Gold Project have the potential to form part of a multi-million-ounce gold system, similar to the nearby four-million ounce Magdala gold deposit, and its targeted, ongoing exploration programs are focused on achieving this outcome.

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 projects in Victoria, Australia (Figure 6).
Navarre is searching for gold deposits in the extension of a corridor of rocks that host the Stawell (~five million ounce) and Ararat (~one million ounce) goldfields. The discovery of outcropping gold at the Irvine Gold Project is a prime focus for the Company. The Project is located 15km south of the Stawell Gold Mine, which Arete Capital Partners has recently acquired from Kirkland Lake Gold Ltd.
The high-grade Tandarra Gold Project is located in close proximity to Kirkland Lake Gold’s world class Fosterville Gold Mine, and 40kms north of the 22 million-ounce Bendigo Goldfield. Exploration at Tandarra is targeting the next generation of gold deposits under shallow cover in the region. Under a farm-out agreement, Catalyst may earn a 51% equity interest in Navarre’s Tandarra Project by spending $3 million over four years to September 2018 by advancing the project towards mineral resource status.
At the Glenlyle Project the Company has identified an epithermal gold-silver system above a potential porphyry copper-gold target that occurs in the same volcanic package that hosts the nearby Thursdays Gossan deposit. Several targets have been generated for reconnaissance drilling.
A potential Fosterville-style high-grade gold mineralisation system is currently being drilled at the St Arnaud Gold Project. Several, previously untested, targets have been identified below shallow cover for a reconnaissance AC drilling program.

Forward-Looking Statements
This announcement contains “forward-looking statements” within the meaning of securities laws of applicable jurisdictions. Forward-looking statements can generally be identified by the use of forward-looking words such as “may”, “will”, “expect”, “intend”, “plan”, “estimate”, “anticipate”, “believe”, “continue”, “objectives”, “outlook”, “guidance” or other similar words, and include statements regarding certain plans, strategies and objectives of management and expected financial performance. These forward-looking statements involve known and unknown risks, uncertainties and other factors, many of which are outside the control of Navarre and any of its officers, employees, agents or associates. Actual results, performance or achievements may vary materially from any projections and forward-looking statements and the assumptions on which those statements are based. Exploration potential is conceptual in nature, 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. Readers are cautioned not to place undue reliance on forward-looking statements and Navarre assumes no obligation to update such information.

Appendix 1 JORC Code, 2012 Edition - Table 1
Section 1 Sampling Techniques and Data
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
Air Core Drilling All air-core (AC) drill holes have been routinely sampled at 1m intervals downhole directly from a rig mounted cyclone. Each metre is collected and placed on a plastic sheet on the ground and preserved for assay sub-sampling analysis as required. Sub-samples for assaying were generated from the 1m preserved samples and were prepared at the drill site by a grab sampling method based on logged geology and mineralisation intervals. Sub-samples were taken at 1m intervals or as composites ranging from 2-5m intervals ensuring a sample weight of between 2 to 3 kg per sub- sample. The sample size is deemed appropriate for the expected grain size of the material being sampled. Certified reference material and sample duplicates were inserted at regular intervals with laboratory sample submissions. |
| Drilling techniques |
Drill type (e.g. core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is _oriented and if so, by what method, etc). _ |
Air Core Drilling AC drilling was carried out using a Wallis Mantis 80 Air- core rig mounted on a Landcruiser base. The AC rig used a 3.5” blade bit to refusal, generally just below the fresh rock interface. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
Air Core Drilling AC drill recoveries were visually estimated as a semi- quantitative range and recorded in the log. Recoveries were generally high (>90%), with reduced recovery in the initial near-surface sample. Samples were generally dry, but many became wet at the point of refusal in hard ground below the water table. No sampling issue, recovery issue or bias was picked up and is considered that both sample recovery and quality is adequate for the drilling technique employed. |
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. The total length and percentage of the relevant intersections logged. |
Geological logging of samples followed Company and industry common practice. Qualitative logging of samples included (but was not limited to); lithology, mineralogy, alteration, veining and weathering. All logging is quantitative, based on visual field estimates. A small representative sample was retained in a plastic chip tray for future reference and logging checks. Detailed chip logging, with digital capture, was conducted for 100% of chips logged by Navarre’s geological team. |
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. For all sample types, the nature, quality and |
Company procedures were followed to ensure sub- sampling adequacy and consistency. These included (but were not limited to), daily work place inspections of sampling equipment and practices. Blanks and certified reference materials are submitted |

| appropriateness of the sample preparation technique. Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. |
with the samples to the laboratory as part of the quality control procedures. Air Core Drilling AC composite, 1m individual and EOH samples were collected as grab samples. Samples were recorded as dry, damp or wet. Drill sample preparation and base metal and precious metal analysis is undertaken by a registered laboratory (ALS Orange, NSW). Sample preparation by dry pulverisation to 85% passing 75 microns. The sample sizes are considered appropriate to correctly give an accurate indication of mineralisation given the qualitative nature of the technique and the style of gold mineralisation sought. |
|
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
Analysis for gold is undertaken at ALS Orange, NSW by 50g Fire Assay with an AAS finish to a lower detection limit of 0.01ppm Au using ALS technique Au-AA26. ALS also conducted a 35 element Aqua Regia ICP-AES (method: ME-ICP41) analysis on each sample to assist interpretation of pathfinder elements. No field non-assay analysis instruments were used in the analyses reported. A review of certified reference material and sample blanks inserted by the Company indicate no significant analytical bias or preparation errors in the reported analyses Internal laboratory QAQC checks are reported by the laboratory and a review of the QAQC reports suggests the laboratory is performing within acceptable limits. |
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. |
Samples are verified by Navarre geologists before importing into the drill hole database. No twin holes have been drilled by Navarre during this program. Primary data was collected for drill holes using a Geobase logging template on a Panasonic Toughbook laptop using lookup codes. The information was sent to a database consultant for validation and compilation into a SQL database. Reported drill results were compiled by the Company’s geologists and verified by the Exploration Manager and Managing Director. No adjustments to assay data were made. |
| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
All maps and locations are in UTM Grid (GDA94 zone 54). All drill collars are initially measured by hand-held GPS with an accuracy of+3metres. On completion of program, a contract surveyor picks-up collar positions utilising a differential GPS system to an accuracy of+0.02m. At the Irvine gold project, topographic control is achieved via use of DTM developed from a 2005 ground gravity survey measuring relative height using radar techniques. Air Core Drilling Down-hole surveys have not been undertaken |
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. |
Variable drill hole spacings are used to adequately test targets and are determined from geochemical, geophysical and geological data together with historic mining information. Drilling reported in this program is of an early exploration nature and has not been used to estimate any mineral resource or ore reserves. |

| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Exploration is at an early stage and, as such, knowledge on exact location of mineralisation, in relation to lithological and structural boundaries, is not accurately known. The drill orientation is attempting to drill perpendicular to the geology and mineralised trends previously identified from earlier AC drilling. Due to the early stage of exploration it is unknown if the drill orientation has introduced any sampling bias. This will become more apparent as further drilling is completed. |
| Sample security |
The measures taken to ensure sample security. |
Chain of custody is managed by internal staff. Drill samples are stored on site and transported by a licenced reputable transport company to a registered laboratory in Orange, NSW (ALS Laboratories). At the laboratory samples are stored in a locked yard before being processed and tracked through preparation and analysis. |
| Audits or reviews |
The results of any audits or reviews of sampling techniques and data. |
There has been no external audit or review of the Company’s sampling techniques or data at this stage. |
Section 2 Reporting of Exploration Results

| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
The Irvine project is located within Navarre’s 100% owned “Ararat” exploration licence EL 5476 which was granted on 25 February 2015 for an initial period of 5 years. The tenement is current and in good standing. The project occurs mainly on freehold land. Crown land, subject to possible Native Title, is under separate exploration licence applications currently being considered by Earth Resources Regulation, Victorian Government. |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
Centaur Mining & Exploration held licence EL 1224 in the 1980s and conducted surface mapping, and shallow RAB drilling along road verges in proximity to the Irvine prospect. The main focus of their exploration activities became the Mt Ararat base-metal sulphide deposit further to the SW. CRA Exploration held licences EL 2651 & EL 3429 (which were amalgamated into EL 3450) in the early 1990s. It was recognised that basalt lavas and associated meta- sediments at the northern end of the field held gold potential of the Stawell-style (which itself was relatively poorly understood at that time). CRA drilled 12 RC holes (average 48m depth) and 2 diamond holes in the Irvine area. This work was initially focused along two north- trending outcrops of ironstone to the west of the Irvine Basalt, now referred to as the Great Western Trend (or Stawell Fault). Significant gold grades of 4m @ 0.88 g/t Au (RC92AA021 from 32m) and 2m @ 2.84 g/t Au (RC92AA027 from 24m) were recorded. Mapping and rock chip sampling across the entire Ararat Goldfield was also undertaken at this time with several >1 g/t Au results obtained. A single diamond drill hole following up two shallow RC holes on the western flank of the Irvine Basalt generated a [email protected]/t Au intersection from 86.5m in a “classic |

| Magdala footwall sequence” of high arsenopyrite and pyrrhotite from meta-sediments in DD92AA254. This was the only hole to pass through the Irvine basalt contact. From 1995 to 1996, under Joint Venture with CRAE, Stawell Gold Mines undertook exploration which included 4 lines of shallow vertical air-core drilling across the trend of the Irvine Basalt. Owing to weather and drill penetration difficulties, no basalt contacts were intersected in any SGM holes and no significant gold results were obtained. The air-core program helped deduce the broad outline of the western basalt contact. A few selected trays from CRAE’s regional drill program are held by the Geological Survey of Victoria in their core farm facility in Werribee. |

| Geology | Deposit type, geological setting and style of mineralisation. |
The project area is considered prospective for the discovery of gold deposits of similar character to those in the nearby Stawell Gold Mine, particularly the 4Moz Magdala gold deposit. The Stawell Goldfield has produced approximately 5 million ounces of gold from hard rock and alluvial sources. More than 2.3 million ounces of gold have been produced since 1980 across more than 3 decades of continuous operation. |
| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collaro elevation or RL (Reduced Level – elevationabove sea level in metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interception deptho hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
Reported results are summarised in Figures 2-4 and Tables 1 & 2 within the main body of the announcement. Drill collar elevation is defined as height above sea level in metres (RL) Drill holes were drilled at an angle deemed appropriate to the local structure and stratigraphy and is tabulated in Table 1. Hole length of each drill hole is the distance from the surface to the end of hole, as measured along the drill trace. |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated. |
All reported assays have been average weighted according to sample interval. No top cuts have been applied. An average nominal 0.1g/t Au or greater lower cut-off is reported as being potentially significant in the context of this drill program. No metal equivalent reporting is used or applied. |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width _not known’). _ |
Air Core Drilling The exact geometry and extent of any primary mineralisation is not known at present due to the early stage of exploration. Mineralisation results are reported as “down hole” intervals as true widths are not yet known. |

| Balanced reporting |
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
All drill hole results received and pending have been reported in this announcement. No holes are omitted for which complete results have been received. |
| Other substantive exploration data |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
All relevant exploration data is shown in diagrams and discussed in text. |
| Further work | The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
Areas of positive AC drill results are expected to be followed up with infill and expansion AC drilling, deeper RC and Diamond drilling in 2018. |
