Key Prospects / Commodities:
Commencement of Drilling Copper-Gold Mineralisation at Granite Flat
-
Percussion drilling to test extent of Copper-Gold mineralisation at Granite Flat
oUp to 24 low impact sites planned to target bulk-tonnage Cu-Au mineralisationoMineralisation remains open at depth and along strike from previous drilling -
Both orogenic gold and multi-commodity porphyry-style mineralisation potential
-
Approved workplan for exploration drilling currently underway
Dart Mining NL (ASX:DTM) (“Dart Mining” or “the Company”) is pleased to report that the company has commenced drilling of copper-gold mineralisation targets at the company’s wholly owned Granite Flat project, NE Victoria. Previous explorers have identified a broad area of gold and copper mineralisation and Dart’s initial focus is to verify and extend previously identified mineralisation.
Drilling Initiation
Dart Mining is commencing exploration of the Granite Flat prospect, beginning with a low impact percussion drilling program and a coincident field mapping campaign to identify the extent of, and controls on copper-gold mineralisation and associated geochemical and geophysical anomalies, as reported in Dart Mining’s October ASX release. EDrill Australia Ltd has been contracted to test the strike extent of known Copper-Gold mineralisation at the Granite Flat prospect. Rotary Air Blast (RAB) percussion drilling works commenced in early November, with this first phase assessment of targets set to conclude in mid-December. Dart Mining is pleased to report that silica-sulphide mineralisation containing abundant sphalerite and common chalcocite, with rare to occasional chalcopyrite has been intersected in the first drill holes. Oxidised zones often show secondary copper minerals such as malachite, azurite and tyrolite (Figure 1). Preliminary assay results are pending, with longer than usual lead times presently being experienced due to the current boom in minerals exploration.

Data obtained from this shallow exploration drilling program will be used to inform plans for a comprehensive, targeted Reverse Circulation (RC) and diamond drilling program in 2021. Previous explorers in the area have constructed a notable network of tracks and drill pads, providing ample worksites available to Dart Mining across several mineralisation targets (Figure 2). In tandem with drilling, Dart Mining is undertaking a regional sampling and geological mapping program to further assess the wider potential of the Granite Flat prosect.

Granite Flat: Project Summary
Granite Flat is located adjacent to the Omeo Highway between Mitta Mitta and Glen Wills, approximately 74 km southeast of Albury-Wodonga and 360 km northeast of Melbourne (Figure 3). The Granite Flat area has a complex geological history, with great potential as a porphyry target due to the polyphase intrusion process of the Devonian Banimboola Quartz Monzodiorite (BQM). Additionally, the Granite Flat area has experienced an orogenic mineralisation overprint along northwest-oriented shears, making the area highly prospective for orogenic gold, as well other precious and base metals (Ag, Cu, Pb, Zn). Preliminary site investigation and previous exploration indicate northwest-trending shear systems bearing lode-style gold mineralisation, which are surrounded by alteration zones containing highly anomalous copper-gold mineralisation (Figure 2), largely comprised of chlorite-altered granodiorite, and disseminated chalcocite and sphalerite. Locally, pods of massive sulphide are present, containing chalcopyrite, chalcocite and sphalerite, and granodiorite and diorite adjacent to fault zones contain disseminated sulphides. Weathering and alteration of these rocks has locally produced malachite-azurite-tyrolite alteration products (Figure 1). A subsidiary north-trending shear system contains localised strong silver-gold-bismuth mineralisation. Given the polyphase nature of the Banimboola Quartz Monzodiorite and the extensive gold and copper soil anomalism, Dart Mining believes that EL006277 has also prime potential to host porphyry-style Au-Cu mineralisation, which will be a strong focus of future exploration in the area.

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. |
• Rotary Air Blast (RAB) drilling was used to obtain 1 m bulk samples (~ 15 kg) which were collected in plastic bags and examined for lithological logging purposes. • Samples off the cyclone were split via a riffle splitter and collected in a calico bag, which was removed every 1m to produce 1m composite samples (~ 1.5kg). The cyclone was cleaned out at the end of each hole and periodically during drilling. • Each 1m composite sample was submitted for analysis. • Samples submitted to ALS were whole sample crushed to 70% <2mm, riffle/rotary split off 1 kg, pulverise to >85% passing 75 microns, then assayed by ALS method AU-AA26 (50g sample aliquot by fire assay). • Certified Reference Materials OREAS 503d, OREAS 504c, OREAS 506, OREAS 235, OREAS 237 and OREAS 245 as well as CRM blank OREAS C27e were inserted every 10 samples as part of a QA/QC system. • Field duplicate sample splits are produced for every tenth sample. • A number of mineralised outcrops have been identified in reconnaissance work by Dart Mining and photographs have been included in the document. Mineralization has been identified by Dart Mining geologists and labelled in the text accompanying the figures. These outcrops have not been sampled by Dart Mining and mineralisation grades for the samples are not known. |
| 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.). |
• RAB drillholes are currently being drilled by EDrill Pty Ltd over the strike extent of mineralised structures. • RAB drilling using a 90mm face-sampling bit • Holes surveyed using a Eastman single shot camera for collar shots.

|
| 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. |
• The location of drill hole collars and geological mapping used a Garmin GPSMAP 62S GPS using the MGA94 Grid Datum (Zone 55) with topographic control taken from the GPS. Accuracy is variable but maintained <5m during the mapping process with constant visual quality assessment conducted. • Handheld GPS is used to survey a control point and drill hole collar positions are then measured by tape and compass relative to the GPS control. The accuracy between holes is <2m but absolute accuracy is relative to the original GPS control point at <10m. • Dart has completed a differential GPS survey of all historic hole collars that were able to be identified as of 2018 to verify the location and accuracy of historic work. • Because of the high probability of RAB hole collapse, and the short length of holes, collar shots were used to survey hole orientation. • All maps, plans and data are on an MGA datum and GDA94 zone 55 projection. • Elevation is established from the GPS control point. • Where available, historic data points have been converted to GDA94 coordinates |
| 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. |
• Drill sites were restricted to existing tracks. It was not intended to establish a drill spacing for resource estimation although these holes may be used at a later date. • 1m assay composites were collected at the splitter on the drill site. This sample interval is considered appropriate for the style of gold- copper mineralisation tested. • All drill related data are referenced to the original ASX report by date published. All details appear in the original report. • The prospect contains several generations of groundwork and a variety of sample spacings. The majority of soil sampling surveys are along 100m-spaced lines with samples taken at 25m intervals. |
| 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. |
• Drilling was restricted to existing tracks. However, in all cases it was possible to drill at a high angle to the host structures and achieve a suitable orientation that cross cuts the mineralisation. True width intersections are provided in drill sections,there appears to be |

no relationship between drill orientation and mineralisation grades, which is oriented along the strike of mineralisation. • Due to the steep grade of tracks and topography, hole orientation was limited or dictated by landscape physiology in some instances. Soil samples are located on a local grid established approximately perpendicular to the trend of gold mineralised structures. • Historic drill holes are generally oriented perpendicular to interpreted mineralised structures in areas where high grade surface results were obtained. |
| 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. |
