ASX Announcement
Navarre Minerals Limited (ASX: NML) (Navarre or the Company) is pleased to report outstanding highgrade gold, silver and copper drilling intercepts at its Mt Carlton United deposit (MCU), part of the recently acquired Mt Carlton Operation (Mt Carlton) in North Queensland (Figures 1 & 2).
With drill intercepts of up to 22.9 grams per tonne (g/t) gold, 1327 g/t silver and 4.2% copper, the results confirm the outstanding grade and continuity of the mineral inventory at MCU, approximately four kilometres southwest of the Mt Carlton processing facility (Figure 2).
The results disclosed in this announcement have not been previously reported and cover 71 holes for a total of 5,451 metres of drilling completed by Navarre during the first quarter of 2022 across MCU. This program is Navarre’s first drilling completed at Mt Carlton since assuming formal ownership of the asset (refer ASX announcement on 15 December 2021).
While drilling continues in 2022 as part of an ongoing exploration program, Navarre anticipates the drilling results in this report will inform an updated resource estimate for MCU which is expected to be published in September 2022, along with updated mineral resources for other Mt Carlton deposits such as V2, Telstra Hill and Crush Creek.
Navarre Managing Director Ian Holland said:
“These outstanding shallow drilling results, returned from our first drilling campaign under Navarre ownership of the Mt Carlton Operation, are extremely pleasing and represent an important milestone since transitioning to become a gold producer.
“The resource definition drilling program has confirmed the continuity, tenor and width of the high-grade gold, silver and copper system of the Mt Carlton United prospect.
“Only four kilometres west of the processing facility, the gold-silver-copper mineralisation defined at MCU has the potential to significantly extend mine life at Mt Carlton.”
The drilling program has involved one reverse circulation (RC) drilling rig and one diamond core drilling rig, with the aim of infilling and extending the known limits of the gold, silver and copper mineralised system as well as providing metallurgical and geotechnical information within the broader envelope of known mineralisation.
MCU Drilling Results
MCU is interpreted to be an intrusion-related, low sulphidation epithermal gold, silver + copper mineralised system, which has significant potential to provide mine life extensions at Mt Carlton. The style of

mineralisation has a similar characteristic to the producing V2 deposit, where early high sulphidation mineralisation has evolved over time to become a lower sulphidation system.
The drilling has focused on improving the definition of the geology and grade continuity within the shallow Inferred Mineral Resources already defined at MCU, as well as providing initial testing for potential depth extensions.
The drill assays are expected to upgrade and expand the existing Mineral Resource at MCU to build critical mass for high-grade new gold developments as potential satellite mill feed to the nearby Mt Carlton Operation. This is in addition to other potential satellite mill feed identified at Telstra Hill and the Crush Creek Project (refer ASX announcement on 30 March 2022).
Details of the MCU drilling program are provided in Tables 1 & 2 and Appendix 1.

Results and Interpretation
A total of 71 resource definition RC and diamond core drill holes for 5,451 metres of drilling have been completed at MCU during the first quarter of 2022 (Figure 3). All assays have been received and are currently being interpreted and geologically modelled in preparation for an updated resource estimate.
This drilling has confirmed two distinct styles of mineralisation. The eastern area is dominated by a closely spaced stacked series of shallow dipping gold, silver and copper mineralised lenses. Several of these lenses contain continuous high-grade gold intercepts across multiple drill holes.
The western area is dominated by gold and silver mineralisation without substantial copper. The geometry of this mineralisation comprises a continuous, high-grade, steeply dipping structure feeding into a stacked set of flat-lying mineralised lenses close to surface. The steeply dipping feeder structure contain multiple high-grade intersections, including an impressive intercept of 7 metres at 14.6 g/t gold and 461.6 g/t silver from 29 metres in RC drill hole MCURC-154 (Figure 4 & Table 2).

| during RC drilling, samples that were affected were recorded by the drillers on their drill plods. For diamond drill holes, core recovery measurements are routinely collected and compared against the drillers core blocks to ensure adequate core recovery. Core loss blocks have been inserted by the drillers and verified by Mt Carlton staff during core markup, with sample intervals adjusted to ensure that core loss zones are not included in the sample interval. Core recovery for all deposits is considered adequate with in excess of 90% recovery recorded for the areas in and adjacent to the mineralisation. The measures in place for the 2022 RC and DD drilling programs are considered suitable to ensure a high level of sample recovery and representivity of the interval. |

RC drill chips have been sieved and collected in chip trays for every 1 m sample. These have been geologically logged by a qualified Geologist capturing the relevant lithological, alteration, texture, weathering and mineralisation attributes of the chips. All intervals are geologically logged for RC drillholes. All logging is captured directly into computers using LogChief software with inbuilt validation processes to ensure data integrity. All drill cores are geologically logged as full core with all relevant lithological, alteration, texture, veining, structure, weathering and mineralisation features collected via LogChief digital data capture. For orientated core, structural measurements are routinely recorded of key geological and mineralisation features to assist with the interpretation and modelling process. All drill cores have been photographed (wet and dry), with these high-resolution photos stored on the site server which is routinely backed up. Drill cores are routinely geotechnically logged, with core recovery, RQD and details of joint spacing and infill collected. All core and RC chip logging is qualitative in nature. |

RC samples were taken as primary splits of bulk samples using a riffle splitter with adjustable sample chutes, attached to the RC cyclone beneath the sample collection box. This has resulted in approximately 3 kg of sample being collected for every 1 m sample. The sample sizes collected are considered appropriate for the style of mineralisation being tested. Samples have been collected dry where possible. In drill holes with excessive water in the sample return resulting in potential contamination have been terminated. Drill core sampling has utilised a diamond core saw to cut the core in half adjacent to either an orientation or cut line. A consistent side of the cut sample has been selected for assaying to minimise any bias through preferential sampling. |

| Sample intervals have been selected by the logging Geologist using prescribed minimum and maximum sample lengths suitable for the mineralisation style being tested. The drill core sample methodology is considered appropriate for the style of mineralisation being targeted at Mt Carlton. Sample preparation of RC and DD samples has been undertaken by external laboratories according to the sample preparation and assaying protocol established to maximise the representation of epithermal style Au-Ag-Cu mineralisation. The sample preparation has been conducted by commercial laboratories. All samples are oven dried (between 85°C and 105°C), jaw crushed to nominal <3mm and if required split by a riffle splitter device to a maximum sample weight of 3 kg as required. The primary sample is then pulverised in a one stage process, using a LM5 pulveriser, to a particle size of >90% passing 75um. Approximately 200 g of the primary sample is extracted by spatula to a numbered paper pulp bag that is used for a 50 g fire assay charge. The pulp and bulk residue are retained at the lab until further notice. Quality control procedures adopted to maximise sample representation for all sub-sampling stages include the collection of coarse-crush laboratory duplicates and the insertion of certified reference material as assay standards (1 in 20) and the insertion of blank samples (1 in 20) or at the geologist’s discretion. It is considered that all sub-sampling and lab preparations are consistent with other laboratories in Australia and are satisfactory for the intended purpose. |

| 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. |
The sampling preparation and assaying protocol used at Mt Carlton has been developed to ensure the quality and suitability of the assaying and laboratory procedures relative to the mineralisation types targeted. Fire assay is designed to measure the total gold within a sample. Fire assay has been confirmed as a suitable technique for epithermal type Au - Ag mineralisation. It has been extensively used throughout the Mt Carlton region. The technique utilised a 50 g sample charge with a lead flux, which is decomposed in a furnace with the prill being totally digested by 2 acids (HCI and HN03) before the gold content is determined by an AAS machine. For some samples gold content was determined using OES instead of AAS with the same detection limit reported. Quality control samples were routinely inserted into the sampling sequence Blank and standard CRMs were inserted every 20th sample. Six (6) different Au grade CRMs have been |

The accuracy of the CRMs is monitored on a batch-by-batch basis using a 2 Standard Deviation tolerance, with the precision of the CRMs monitored over time by comparison between the expected CRM assay and the mean of the CRMs of a specific time period. Coarse-crush duplicates have been inserted every other 20th sample. A tolerance of 10 times the detection limit is applied when analysing the performance of the blank, with any batch that contains a blank failing this threshold reanalysed. Batches which fail quality control checks are re-analysed. ICP multielement analysis was conducted for all holes in addition to the gold analysis. For resource definition and some exploration holes, either 4-acid ICP-MS or 4-acid ICP-OS was used. For most exploration holes, 9 out of 10 samples were assayed by ICP-OS using an aqua regia digestion and every 10th sample analysed by ICP-MS with a 4-acid digestion. |

| 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. |
No external verification has been completed on the intercepts included in this announcement, although the individual intercepts have been reviewed by Company personnel against the RC chip trays and DD core photos to ensure that the mineralisation as logged is consistent with the reported intersections. Comparisons between the different drilling methods are routinely completed as part of the database validation process completed during the interpretation and modelling of the mineralisation. The quality control / quality assurance (QAQC) process ensures the intercepts are representative for epithermal gold systems. Sample pulps are retained for when further verification is required. A number of the DD drill holes in this release are effectively twinned drill holes of existing RC drill holes. Comparative analysis between the two methods for these intercepts indicates no systematic bias. Assay data is loaded directly into Datashed in batches. In-built checks in Datashed flags errors and ensures batches pass validation checks prior to upload. Validation checks include mis-matching sample numbers, inconsistent “depth to intervals” etc. A batch QAQC control chart report is generated once the batch is successfully loaded. Visual checks of standards, duplicates and blanks of reported assays are also conducted before batches are uploaded into Datashed. Assay |

This drilling program is within ML10343. The ML area covers 1151.9 ha. Native title agreements are in place for activities within the Mining Lease, and surrounding EPM’s. ML 10343 is surrounded by a number of EPM’s forming the Mt Carlton project area, with ML10343 within EPM10164. The Mt Carlton project currently covers 875km2, the EPM’s are in good standing with no significant risk regarding land access which inhibit future work. A royalty agreement is currently in place between Conquest Mining Pty Ltd and Gold Fields Australasia Pty Ltd. |

Acknowledgment and appraisal of exploration by other parties. |
Exploration within the Mt Carlton EPM’s and ML10343 commenced in the 1970’s, with BHP, Ashton Mining, MIM exploration and others exploring the Capsize Range area within the current EPM10164 for porphyry copper and epithermal styles of mineralisation. In 2006, Conquest Mining discovered the V2 high sulphidation epithermal Au-Cu deposit, and Ag-rich A39 deposit, with follow up work within the ML10343. |
| Geology | Deposit type, geological setting and style of mineralisation. |
Mt Carlton United is hosted within Early Permian Lizzie Creek Volcanic Group rocks close to the northern margin of the Bowen Basin. Mineralisation at Mt Carlton ranges from high sulphidation to lower sulphidation epithermal Au-Ag-Cu mineralisation. Mt Carlton United is considered to be an intrusion-related low sulphidation epithermal Au-dominant deposit, hosted within rhyodacite volcanic and volcaniclastic sequence. Mineralisation in the central and eastern parts of the deposit occurs in a series of stacked shallowly dipping mineralised horizons, whereas in the western area, the mineralisation is flatter lying and is interpreted to be more heavily influenced by supergene processes. A moderate to steeply high-grade feeder structure has been identified in this western area, with a |
