Mt Elmo Goldfield Vein Gold Mineralisation, Northeast Victoria

“extensive strike length indicates substantial exploration potential for high grade gold mineralisation”

Dart Mining NL (ASX:DTM) (“Dart Mining” or “the Company”) is pleased to report encouraging results from preliminary reconnaissance sampling of the Mt Elmo Goldfield, near Eskdale, in Northeast Victoria. Significant historic workings display multiple lines of silica-sulphide gold mineralisation across a significant strike length of more than 4 km, with workings indicating that mineralisation is open at depth and along strike.

Highlights Include:

• Significant strike of mineralised structures indicated by preliminary mapping and sampling, as well as LiDAR identifications of historic workings and pit chains

• Promising reconnaissance sampling include:

• 0.2m @ 38.3 g/t Au & 22 g/t Ag

• 0.2m @ 13.5 g/t Au

• 1.0m @ 7.0 g/t Au

• Grab samples at 64 g/t Au & 5.4 g/t Au

• Recent fires and LiDAR imagery have clearly identified existing access tracks and drill pads

Chairman, James Chirnside commented : “ Preliminary mapping and sampling indicates the Mt Elmo Goldfield displays strong orogenic gold prospectivity, and we are particularly encouraged by the substantial strike length indicated for the vein gold mineralisation. Although high-grade samples can be typical of NE Victorian Gold, mineralised strike extents of this magnitude are not common. Once again, our recently completed LiDAR survey has proven to be of enormous value”.

Introduction & Overview

Dart Mining has recently undertaken some reconnaissance sampling on the Mt Elmo Goldfield to gauge indications of mineralisation style, extent, and grade. Preliminary results indicate narrow-vein mineralisation, repeated on multiple adjacent structures (Figures 1 & 2), and with good potential for stockwork mineralisation and wider, high-grade shoots. The combination of field mapping, sampling, and interpretation of airborne LiDAR mapping of the area (Dart ASX 18[th] March 2021) has identified a series of parallel, north-northwest trending and steeply northeast dipping structures. Mineralisation is hosted by vein-style, silica-sulphide mineralisation, typically 0.3–0.6 m wide, although occasionally widening to >1m in width and forming steeply plunging shoots typical of Northeast Victorian orogenic gold systems.

The Mt Elmo Goldfield appears to demonstrate remarkable continuity of mineralisation along significant strike lengths, and the addition of repeated, parallel structures suggests good potential for a viable exploration project. Although further exploration is needed, this project suggests good indications of width potential via the close proximity of multiple vein systems, and broader zones of stockworking associated with these veins. Additional shoots of high-grade gold mineralisation are indicated by historic records, which indicate notable volumes of high-grade ore (e.g., 123 tonnes @ 103 g/t from the Highland Chief, Upper Murray & Mitta Mitta Herald, 1903) and supported by chip samples at 38 g/t (70448), mullock grab samples of 64 g/t (sample 70454) and 202 g/t Au (Caluzzi, 1995).

Two particularly long and continuous lines of workings, the Smythe & Willard and the Goodwin & Shea lines can be traced over a strike extent of 4.0 km, although the Premier Mine to the north, and the Redjacket (beyond the scale of Figure 1) and other associated workings to the south suggest that the strike extent of the mineralised system may extend over 8.5 km. Gold mineralisation is hosted in association with abundant pyrite and arsenopyrite, with the gold mineralisation itself hosted in gold tellurides (calaverite, AuTe2; Figure 3a), with minor lead and copper sulphides present (galena and covellite replacement of chalcopyrite; Graham & Masterton, 1987).

Sampling

Of the eleven reconnaissance samples collected across selected and accessible areas of the Mt Elmo Goldfield, all but one display encouraging gold mineralisation (>1 g/t Au), including 1m @ 7.0 g/t Au , 0.2m @ 38.3 g/t Au & 22 g/t Ag , 0.2m @ 13.5 g/t Au and a grab sample at 64.2 g/t Au (Figures 1 & 2). All gold assay results are shown in Table 1, with additional base metal assay values in Appendix 1. Sampling from the Victoria workings was completed along the backs every 50m down the drive, along with a mullock grab sample (69575). All chip samples from the Victoria workings include 0.2-0.3m wide laminated silica-sulphide mineralisation with abundant pyrite and arsenopyrite hosted within sheared argillite (Figure 3b). Three short chip samples were collected from accessible portions of the Wizard Prince workings which included two samples of silica-sulphide mineralisation (70448, 70449) and one sample of altered sandstone displaying disseminated pyrite and jarosite. The remaining samples from the Highland Chief and Monarch workings (samples 70451-70454) are comprised of silica-sulphide mullock grab samples, including a 15cm grab sample from the Monarch workings which assayed at 64.2 g/t Au and displays visible calaverite (Figure 3a).

Detailed data processing and ongoing review of LiDAR and supplementary geospatial data collected across the Mt Elmo Goldfield by GeoCloud Analytics Ltd. has identified a significant number of previously unmapped historic mine sites and workings and has been able to resolve differences in the character of historic tin and gold workings enabling accurate, high-resolution mapping and drastically increasing efficiencies in the field (e.g., Figures 1 & 2). Additionally, LiDAR imagery has clearly identified drill access tracks and pads that were constructed by Stonewick Enterprises Ltd. in the late 1980’s but never utilised.

Project History

The Mt Elmo Goldfield was discovered late in the Victorian goldrush in the 1890’s and sits alongside other similar discoveries in the nearby Tallandoon, Mitta Mitta and Sandy Creek Goldfields. Mining in the Mt Elmo Goldfield started around approximately 1897 and continued until 1914, after which there was sporadic mining occurrences through to the 1930’s. Production records from the Mt Elmo Goldfield are sparse and incomplete. The records that are available indicate an average grade from the Victoria Mine of 66 g/t Au, an average grade of 119 g/t Au from Highland Chief (which includes several crushings at ~7 oz/t), and an average grade of 54 g/t Au from the Monarch workings. At least one shaft on the Mt Elmo Goldfield was worked to a depth of 350m (Dickenson’s Shaft; Ovens & Murray Advertiser, 1908).

The goldfield went through a renewed period of exploration in the 1980‘s when Stonewick Enterprises Ltd. undertook a notable amount of prospecting which included comprehensive sampling and mapping of a number of workings and adits, as well as constructing several access tracks and drill pads that were never utilised. Between 1985-1988 Stonewick Enterpises Ltd. collected 652 rock chip samples, with a peak result of 202 g/t Au in a mullock grab sample from the Highland Chief (Goodwin & Shea line) workings. Prior to Dart Mining taking on EL5315, Northern Mine Ventures Ltd. undertook preliminary sampling across the Elmo Goldfield.

Future Exploration

As the majority of workings have either collapsed or been intentionally blocked, a ridgetop soil sampling program is proposed to test the strike extent of the various mineralised structures, with targeted soil grips in particularly prospective localities. Additionally, as the Elmo Track bisects the mineralised structures in multiple places, a small-scale low impact RC drilling program is proposed to further characterize the depth and extent of mineralisation. A small, low impact exploration work program has already been approved and we expect to undertake the program early in 2022.

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 30 g 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.	• Chip samples are taken continuously perpendicular to the general strike of mineralised structures in outcrop, and large samples (4 – 7kg) are taken where possible to provide a more representative sample. The chip samples are of adequate quality to be indicative of the area sampled. • Grab samples were collected from the outcrop over a small area (<1 – 5m in diameter). The grab samples are generally small (ie. <7kg) and represent the local area only, sampling only tests a small aerial extent, and are not considered as being representative of the outcrop. The grab samples are of adequate quality to be representative of the small area sampled and approximate the sampled in situ mineralisation. • Rock samples are dried, crushed and whole sample pulverized and riffle split. A sample aliquot (50g) is taken for analysis. Gold has been analysed by ALS Method Au-AA26 – a fire assay technique for total digestion. Samples submitted to ALS were whole sample crushed to 70% <2mm, riffle/rotary split off 1 kg, pulverised to >85% passing 75 microns, then assayed by ALS methods AU-AA26 (50g sample aliquot by fire assay), ME-MS61 (0.25g sample aliquot by four-acid digest and ICP- MS and ICP-AES analysis). • LiDAR data was acquired using a Teledyne Optech sensors. • LiDAR data was collected across 576km2 area in Northeast Victoria. • Project design vertical accuracy was 0.10m on clear ground at one sigma, with at least four points • emitted per square metre, with up to eight returns per emitted point. • LiDAR data was georeferenced using CORS base station data. • Data classification is ICSM Level 2 (ground, non-ground, vegetation and structures, etc). • Data classification was manually checked and edited against georeferenced digital • orthophotography and/or intensity imagery acquired as part of this project. • Elevation data will be gathered as WGS ellipsoidal heights and will be adjusted to orthometric heights by applying a correction to every data point using the relevant geoid model. • LiDAR data was delivered in industry-standard LAS formats, plus a 0.5m ground grid in ASCII • Format and GeoTIFF. • The flyingheight for aerial data acquisition was approximately2000m above

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.	• No drill-related data are available for the Mt Elmo prospect. • The location of drill hole collars and geological mapping confirmed using a Garmin GPSMAP 66i GPS, set to MGA94 Grid Datum (Zone 55) with topographic control taken from the GPS. Accuracy is variable but maintained <3m during the mapping process with constant visual quality assessment conducted. • Mine workings are located using GPS control and then tape and compass survey for underground development. • All maps, plans and data are on an MGA datum and GDA94 zone 55 projection. • Elevation is established from the GPS control point. • LiDAR data was collected across 576km2area in Northeast Victoria. • Project design vertical accuracy was 0.10m on clear ground at one sigma, with at least four points emitted per square metre, with up to eight returns per emitted point. • Data classification was manually checked and edited against georeferenced digital orthophotography and/or intensity imagery acquired as part of this project. • Elevation data will be gathered as WGS ellipsoidal heights and will be adjusted to orthometric heights by applying a correction to every data point using the relevant geoid model. • LiDAR points were collected at 0.5m intervals, with a minimum of 4 points per square metre. Vertical accuracy is 0.1m. • At the scale and resolution of the features being identified and resolved, the data spacingis more than adequate.
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.	• Where exposure allows, multiple chip samples are collected across mineralised structures to assess the continuity of Au grade. • Rock chip sampling is limited by outcrop exposure. • Reconnaissance-scale chip / grab samples are not presented or considered to be representative of the average grade. Grab samples only represent the grade at a single point within the rock exposure. Sample spacing is designed to allow an initial assessment ofgold mineralisation and is not suitable for future resource

		estimation activities.
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.	• Grab samples do not capture any aspect of the potential variation in grade in relation to the orientation of the mineralisation and represents only a single point inside the mineralisation. Chip samples are collected perpendicular to strike where possible to avoid any sample bias and only where outcrop or subcrop exists. The orientation of rock chip samples is recorded. • No significant sample bias is considered to be introduced because of the orientation of sample transects without being noted in the body of the report. • LiDAR data represents the surface area of the area regions surveyed, with X,Y and Z data reported for across topography of a predefined areas. • LiDAR survey areas are completely independent of mineralisation or structural style and are therefore considered unbiased.
Sample security	• The measures taken to ensure sample security.	• All samples submitted for analysis are placed in sealed poly-weave bags and delivered to a commercial transport company for delivery to the laboratory. Any evidence of sample damage or tampering is immediately reported by the laboratory to the company and a decision made as to the integrity of the sample and the remaining samples within the damaged / tampered bag/s. • LiDAR data is confidential, and only accessed by Dart Mining representatives, AAM Group& GeoCloud Analytics.
Audits or reviews	• The results of any audits or reviews of sampling techniques and data.	• An internal review of procedures, operations, sampling techniques and analytical techniques was made by Dart Mining. • The mapping, sampling methodology and results were documented and reviewed by the competent person for this report. • All assay data is validated upon entry into the EarthSQL Quest database. • Airborne LiDAR survey included field test points of survey areas located in accessible areas. • LiDAR test points were used to test and validate the achieved accuracy of the LiDAR. • Results of test point comparisons and achieved accuracy reported in the project metadata. • LiDAR data was georeferenced using CORS base station data. • Feld surveywork and data validation was undertaken byAAM Group.

Exploration done by other parties	• Acknowledgment and appraisal of exploration by other parties.	• Between 1985 and 1988 the Mt Elmo Goldfield was actively explored by Stonewick Enterprises PTY Ltd. under EL1395. Stonewick Enterprises were exploring for quartz-vein hosted mineralisation in the Elmo Goldfield and collected more than 652 chip samples and mapped a significant number of workings throughout the Mt Elmo Goldfield. Northern Mine Ventures PTY Ltd undertook a small amount of chip sampling and exploration on the Mt Elmo Goldfield under exploration licence EL5315 between

		2012 and 2017, prior to Dart Mining NL obtaining EL5315 in 2017 with the principle objective of identifying Lithium-Caesium-Tantalum (LCT) and tin-bearing pegmatite dykes.
Geology	• Deposit type, geological setting and style of mineralisation.	• EL5315 and EL006486 are located in the Omeo structural zone of the Lachlan Fold Belt in eastern Victoria. The EL’s are underlain by metamorphosed Lower Ordovician Pinnak Sandstone and its higher-grade metamorphic equivalents in the Omeo Metamorphic Complex to the west. • The Mt Elmo Goldfield was a traditional narrow-vein, high-grade, reef-style goldfield. Gold mineralisation occurs in association with abundant pyrite, arsenopyrite and tellurides.
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 collar o elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o 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.	• N/A • No drill-related data are available for the Mt Elmo prospect.
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.	• N/A • No drill-related data are available for the Mt Elmo prospect.
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’). _	• N/A • No drill-related data are available for the Mt Elmo prospect. • All chip samples are oriented perpendicular to the strike of narrow-vein mineralisation and are representative of true width of the mineralised structure at the sample position.
Diagrams	• Appropriate maps and sections (with scales) and tabulations of intercepts should be includedfor any significant discovery being reported These should	• The location, width/sample nature, and grade of preliminary reconnaissance samples covered in this report ispresented in Figures 1 &2.

	include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.
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 grade details and intercepts are included in the body of the report and in Appendix 2 of this release. • Summary (weighted average) grade intersections is provided as cross sections and tabulated data referenced in the bodyof the report.
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.	• Any other relevant information is discussed in the main body of the report.
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.	• Planned work is discussed in the body of the report and is dependent on future company direction.
