Report to Shareholders

Highlights

  • Major focus on Tandarra Gold prospect, 40 km north of Bendigo with program of diamond, reverse circulation (“RC”) and air-core drilling approximately 50% complete.

  • Tandarra drill program results confirm and expand original theories on similarities to Bendigo Goldfield quartz reef accumulations.

  • Multiple shallow, moderate to high grade gold drill intercepts returned from Tandarra RC drilling including: 4m @ 9.2g Au/t from 18m down-hole in RCT063; 4m @ 9.4g Au/t from 44m down-hole in RCT050; and 6m @ 3.1g Au/t from 40m down-hole in RCT062.

  • Resource definition drill results received to date demonstrate significant shallow and potentially economic gold mineralisation over a strike length of 650m at Tandarra within a 2.5km zone previously established by air-core drilling.

Summary

Navarre’s $4.2 million exploration program of drilling and geophysics over the Tandarra Gold prospect is one of the largest greenfields gold exploration projects in Victoria. Tandarra is at the centre of the Company’s Bendigo North Gold Project, 40 kilometres north of Bendigo, in Victoria, Australia. Significant progress towards the goal of delivering a maiden mineral resource was achieved during the quarter including:

  • completion of 71 reverse circulation (“RC”) and 5 diamond drill holes for 7,336 and 855 metres respectively;

  • continued demonstration with RC drill results received to date that near surface moderate to high-grade gold mineralization on the Tomorrow Line extends over a strike length of at least 650 metres; and

  • confirmation by diamond drilling that Tandarra geology and mineralisation is analogous to the Bendigo Goldfield.

Finance

  • Cash in bank was $3.7 million at 31 March 2012 ($4.8 million at 31 December 2011).

  • Formal agreements signed with ASX-listed Castlemaine Goldfields Limited for Navarre to farm-in to the prospective Raydarra and Sebastian tenements, adjacent to and south of Tandarra.

Outlook

  • Drilling program at Tandarra continues during the June quarter with RC, diamond and air-core rigs active.

  • Trial geophysical surveys to be undertaken at Raydarra and Sebastian Gold Projects.

  • Initial air-core drill program to commence at Raydarra.

1. BACKGROUND

Navarre Minerals Limited (ASX Code: NML) is an Australian gold and base metals exploration company with projects located in central and western Victoria with the potential for large gold and copper-gold-zinc deposits.

Navarre’s goal is to define a maiden mineral resource and to become a low-cost, significant Victorian gold producer through exploration success.

2. EXPLORATION

2.1. BENDIGO NORTH GOLD PROJECT (Tandarra prospect, EL 4897 & EL 5364)

The Bendigo North Gold Project is a recent greenfields gold discovery under shallow cover, 40 kilometres north of the 22 million ounce Bendigo Goldfield (Figures 1 & 2).

Navarre’s focus during the quarter was continuation of a resource definition RC drill program and commencement of diamond drilling at the Tandarra prospect. Several high-grade gold results were returned from RC drilling during the quarter. Highlights include:

  • 4m @ 9.2g Au/t from 18m down-hole, including 1m @ 30.9g Au/t, in RCT063;

  • 4m @ 9.4g Au/t from 44m down-hole, including 1m @ 33.6g Au/t, in RCT050;

  • 24m @ 2.5g Au/t from 35m down-hole, including 3m @ 10.9g Au/t and 1m @ 15.3g Au/t, in RCT006;

  • 6m @ 3.1g Au/t from 40m down-hole, including 4m @ 4.5g Au/t, in RCT062;

  • 5m @ 3.9g Au/t within 12m @ 1.8g Au/t from 73m down-hole in RCT028; and

  • 2m @ 5.5g Au/t from 77m down-hole, including 1m @ 10.3g Au/t, in RCT069.

  • *All results are reported as down-hole lengths. A full suite of results for Q1 2012 is provided in Table 1.

To date, significant gold intercepts returned from RC drilling occur over a strike length of 650m, which is expected to expand with further results from within the 2.5km of strike previously outlined by scout air-core drilling (Figure 3). The results are believed to be supportive of a conceptual open pit. The Company is working towards demonstrating the economic potential of a mining operation targeting high-grade, unevenly distributed pods of gold contained within broad zones of gold in quartz mineralisation.

During the quarter, 71 RC holes were drilled for 7,336 metres with a further 4,000 metres scheduled to be completed before the RC rig leaves site at the end of April 2012. In addition five diamond holes for 855 metres were drilled during the quarter in order to aid interpretation of RC drill intercepts for resource modeling purposes.

During the quarter, a significant backlog of results built up at the assay laboratory (3,582 samples have been processed to date, while 1,315 remain with the assay laboratory). The Company is working closely with the laboratory to ensure this backlog clears as quickly as possible.

All assay results have been determined by Leachwell[©] (24 hour) cyanide leach 2,000g analysis. A series of external standards and blanks are used to assess laboratory assay quality control. All samples intervals are 1m in length. All reverse circulation samples have been recorded as dry and samples are split using an on-board rotary splitter. Intervals are length weighted grade average. True widths are yet to be determined. NSR refers to no significant results. There has been insufficient drilling undertaken on the Tandarra prospect to define a Mineral Resource and it is uncertain if further exploration will result in determination of a Mineral Resource.

Farm-in agreement on ground to the south of Tandarra

On 20 February 2012 Navarre and Castlemaine Goldfields Limited (ASX Code: CGT) announced that they had finalised two farm-in agreements covering the Raydarra and Sebastian Gold Projects, located to the south of Tandarra (Figures 1 & 2). Under the terms of the deal, Navarre may earn up to a 75% interest in the Projects.

During the quarter, Navarre completed a trial line of geophysics at Raydarra. Following encouraging results from that survey, the Company commenced a six hole air-core drill program on 19 April 2012 to test four geophysical targets that appear to be continuous with quartz reefs identified on Navarre’s Tandarra prospect. The Raydarra Project is similar to Tandarra insofar as it sits on a “buried hill” or dome covered by a thin veneer of Murray Basin sand and clay and where the depth to the top of the basement rocks is as shallow as 6 metres.

2.2. KINGSTON GOLD PROJECT (EL 5280 & ELA 5380)

The Kingston Gold Project is 30 kilometres northeast of the 5 million ounce Stawell Gold Mine operation in western Victoria (Figure 1). Kingston is an historic gold mine and the Company is following-up several previous high-grade gold intercepts. Historic gold workings occur within a northeast trending zone of quartz stockwork veining and associated brecciation defining an area of approximately 100m wide and over 1 kilometre in strike length (Figure 4).

On 24 January 2012 Navarre announced a diamond drill result of 16.9m at 5.5g Au/t from a depth of 65.7m down-hole, including 3.1m at 29.5g Au/t, in DDK001. Visible gold was also identified in DDK001 between 65.7m and 65.9m down-hole on the upper or hangingwall contact of a quartz lode structure. DDK001 was drilled targeting high grade gold mineralisation 10m north of percussion hole KINC058 which intersected 9m at 40.5g Au/t from 78m down-hole (Figures 4 & 5).

==> picture [596 x 62] intentionally omitted <==

Results from diamond holes DDK002 and DDK003 were received during the quarter. Low gold grades were returned for these holes despite both intersecting a large quartz lode structure. Navarre believes that these results are consistent with the nuggety nature of gold mineralisation reported historically at the Kingston Mine prospect (Table 2).

All assay results have been determined by fire assay with AA finish. A series of external standards and blanks are used to assess laboratory assay quality control. All samples intervals are based on cut half core samples of varying lengths of up to 1.5 metres based on geological intervals. NSR refers to no significant results. Core recovery for reported intervals is moderate to high. Core loss intervals are ascribed a zero gold grade. Intercepts are down-hole lengths with grades weighted for length. True widths are not known. There has been insufficient drilling undertaken on the Kingston Mine prospect to define a Mineral Resource and it is uncertain if further exploration will result in determination of a Mineral Resource.

Other activity during the quarter includes the completion of a 4,200 line kilometre airborne magnetic survey across the old Kingston Mine and Landsborough Fault. This data will be analysed in the second quarter to identify regional drilling targets.

The Landsborough Fault is believed to be a major control on gold mineralisation in the region. In April 2012, the Company was granted exploration licence EL 5380 (Glendhu), covering 185 square kilometres of the Landsborough Fault adjoining the southern end of the Kingston Gold Project (Figures 1 & 6). Navarre now has a dominant land position along the Landsborough Fault (refer Figure 6), a parallel fault system to the nearby Stawell Fault which is considered to be a controlling structure for over 6 million ounces of historic gold production from the Stawell and Ararat Goldfields.

2.3. BLACK RANGE BASE METALS PROJECT (EL 4973, EL 4590 & EL 5164)

The Black Range Project is a base metals and gold exploration target in the Grampians – Stavely region of western Victoria (Figure 1). The project area contains about 60 kilometres of Cambrian age volcanics that show pronounced geological similarities to the Mount Read Volcanics (“MRV”) of northwest Tasmania, which are host to a number of volcanic massive sulphide deposits such as Rosebery, Hellyer and Que River and the large Mt Lyell copper-gold deposit.

An independent review of the geology and exploration conducted to date on the Black Range Project is underway and expected to be completed in the second quarter of 2012 by a consultant from the Centre of Excellence in Ore Deposits (“CODES”) at the University of Tasmania. CODES are experts in Tasmania’s MRV and Navarre awaits the final report to assist with target generation.

2.4. BALLARAT SOUTH GOLD PROJECT (EL 4996)

No exploration progress to report as the Company continues to prioritise Bendigo North and Kingston.

Competent Person Declaration

The information in this release that relates to Exploration Results, Mineral Resources or Ore Reserves is based on information compiled by Steve Harper, who is a Member of The Australasian Institute of Mining and Metallurgy and who is Chief Geologist of Navarre Minerals Limited. Mr Harper has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration, and to the activity which he is undertaking, to qualify as a Competent Person as defined in the 2004 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Mr Harper consents to the inclusion in the release of the matters based on his information in the form and context in which it appears.

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.
