Dart Mining NL (ASX:DTM) (“Dart Mining” or “the Company”) is pleased to report that assay results have now been received for the Reverse Circulation (“RC”) percussion drilling program completed in late 2020 at the Phoenix Hill – Chinaman’s Gully prospect. The drilling focused on testing the mineralisation model at Phoenix – Chinaman’s Gully, focusing on targeting quartz vein and stockwork-hosted orogenic, epizonal gold mineralisation at the Company’s wholly-owned Rushworth Gold Project in Central Victoria.

Dart Mining contracted EDrill Ltd. to drill 44 holes across four transects at 5 metre intervals, for a total of 1270m of drilling (Figure 1). The transects were oriented to target the Phoenix mineralisation system, where interpretations indicate repeated mineralised limb thrust faults cross-cutting folded strata of the Phoenix Anticline (Dart ASX 16[th] November 2020).
Preliminary examination of drilling results and geological logging indicate the model is valid, with several significant intersections encountered (Table 1) and multiple lines of mineralisation evident along the drill transects (Figure 2). Several holes, particularly along transects C and D, intersected old workings or stopes, demonstrating the presence of the mineralised system, however, did not produce samples through the entire structural horizon (see Appendix 1 – Hole Details).
Table 1: Selected significant intercepts from the recent drilling program at Rushworth, Central Victoria. Intervals determined using a cut-off grade of 0.2 g/t Au, and no greater than 2m of internal dilution. A complete list of intersections is included in Appendix 2.

Discussion of Results
Drilling was undertaken under a low impact workplan, with transect location dictated by existing track and drill pads and the strike of mineralised structures. Results of this drill program, previous drilling completed by New Holland Mining Ltd. and geological mapping (Boucher, 2016; Jones & Turnbull, 2016; Dart ASX 16[th] November 2020), indicate that mineralisation remains open at depth and across more than 600m of strike, with multiple lines and orientations of mineralised structures evident (Figures 1, 2 & 3).
Samples were assayed for gold by a 2 kg Leachwell method with fire assay of tails completed to best determine true gold grade. Fire assay of tails showed that >95.5% of gold was recovered through the Leachwell analysis. The large sample size was to account for the nuggety nature of the mineralisation style at the Phoenix project that has previously been demonstrated by Jones & Turnbull (2016) and Boucher (2016).

Notably, visible gold was observed in percussion chips logged by the site geologist in hole RCRC08 between 18-19m downhole, which graded 1m @ 10.8 g/t Au . Other significant high-grade results include 1m @ 9.13 g/t Au in RDRC12 from 4m and 1m @ 7.1 g/t Au in RDRC03 from 18m. Long intersections in holes RBRC08 ( 19m @ 1.1 g/t Au), RCRC01 ( 21m @ 0.35 g/t Au ), RCRC02 ( 13m @ 0.44 g/t Au ) and RDRC06 ( 17m @ 0.54 g/t Au ) are particularly significant and demonstrate that gold grade is not always directly related to quartz reef-style mineralisation and is potentially indicative of stockwork mineralisation zones (Figure 2). Drill transects have demonstrated that multiple, shallow lines of mineralisation exist across the Phoenix Prospect. Deeper, low grade intersections in RARC09 (2m @ 0.62 g/t Au between 59-61m; & 1m @ 0.69 g/t Au between 92-93m) provide an indication of additional mineralisation at depth, an aspect that has been poorly tested in the Rushworth goldfield.

Future Exploration
Future work at the Phoenix-Appleton’s-Chinaman’s Gully prospect will focus on testing for strike and depth extensions to the multiple gold mineralised structures intersected in the recent drill program. Due to the nuggety nature of the mineralisation at the prospect (Dart ASX 16[th] November 2020), future work could also involve collating entire RC sample residues for bulk sample processing to provide an accurate assessment of gold mineralisation grade. Additional holes on the south end of transect A, and particularly transect C, are proposed to further intersect mineralised limb thrusts.

Dart recently received additional grants of exploration licences at Rushworth (Dart ASX 10[th] February 2021) and now has 100% ownership of the entire Rushworth goldfield. The Company will also turn its attention to evaluating exploration targets across the entire area, where historic mining exploited high grade reefs, often showing spectacular grades, over a cumulative 14km strike length.
Rushworth Gold Project
The Rushworth Goldfield is located in Central Victoria, 140 km north of Melbourne, and 65 km east of Bendigo. The Rushworth Goldfield is well-exposed, with the host strata exposed at surface. These strata have been tightly folded into upright, east-west trending folds, and two primary lines of gold-quartz veining that extend for a cumulative strike length of 14 km. Gold mineralisation is interpreted to be an orogenic, epizonal style similar to that forming high-grade gold shoots at the nearby Fosterville Mine. Within the Rushworth Goldfield, mineralised quartz veins have been intersected at depths beyond 400m in historical workings, and up to 200m in modern drill holes. Historical workings rarely proceeded beyond the water table, leaving most veins untouched at depth.
Following the recent success at Fosterville, and the currently heightened state of interest in Victorian goldfields, competition for tenure in this area of Central Victoria is fierce. Dart Mining’s strategic 254 km[2] landholding in Central Victoria spans the entire historic Rushworth Goldfield, and is bordered by Chalice Goldmines to the northwest, Newmont Mining to the west, and Nagambie Resources to the south and east.

About Dart Mining
Dart Mining (ASX: DTM) floated on the ASX in May of 2007 with the aim of evaluating and developing several historic goldfields, as well as substantiating a new porphyry province in North East Victoria. The area is prospective for precious, base, and minor metals. These include Lithium, Gold, Silver, Copper, Molybdenum, Zinc, Tungsten, Tin, Tantalum, and a host of other important minerals. Dart Mining has built a strategically placed gold exploration footprint in the Central and North East regions of Victoria, where historic surface and alluvial gold mining indicates the existence of significant gold endowment.

| Exploration done by other parties • Acknowledgment and appraisal of exploration by other parties. • Gold was discovered in Rushworth in August 1853, and for several years production was from alluvial workings. This developed into reef workings by 1860. Mining had almost completely ceased by 1914 and attempts to revitalise the goldfield since have been met with no success. • Garratt (1985) calculated at least 97,000 oz of gold was produced from the Rushworth Goldfield, with a further 40,000 oz from the Whroo Goldfield 6km to the south of Rushworth. These figures are considered an absolute minimum for production due to poor record keeping prior to the 1860’s and the number of small, unrecorded workings in the district. • A detailed soil sampling survey of over 1200 samples were collected across a 6 km2 area by New Holland Mining N. L. • A series of 26 RAB holes were drilled across the Nuggety Hill – Specimen Hill prospect by New Holland Mining N.L. in 1993. Several significant intersections were identified, including 3m at 10.1 g/t, 3m at 3.16 g/t, and 3m at 3m at 2.83 g/t. The highest grades typically occurred between 50-60m down hole, and grade often displayed gold enrichment near the surface and approaching the water table. Notably, drilling stopped at the water table. • In 1994 New Holland Mining N. L. drilled 909m across 14 RAB drill holes across the Star of the West prospect, and 896m across 12 RC holes on the Nuggety prospect, 924m were drilled across 14 RC holes on the Fletchers Reef section of the Phoenixprospect. A review and |

| Geology | • | Deposit type, geological setting and style of mineralisation. | • | EL006016 is located in the Melbourne structural zone of the Lachlan Fold Belt in central |
| Victoria. The EL is underlain by metamorphosed Upper Silurian to Lower Devonian age | ||||
| Melbourne Group sediments. A Bendigo-style mineralisation model in folded turbidite | ||||
| sequence with late-stage brittle faulting and late gold mineralisation is interpreted across the | ||||
| Phoenix Hill-Appleton’s-Chinaman’s Hill prospect at Rushworth, with nuggety gold | ||||
| mineralisation observed on thrust-fault related flat veins, saddle reefs and AC joints. | ||||
| • | The exploration rationale applied by Dart Mining is in line with the significant work previously | |||
| undertaken across the tenement, targeting large thrust fault style reef systems and cross | ||||
| course faults, known to show high grade mineralisation and having potential for large tonnage | ||||
