GRANITE FLAT Cu-Au PROJECT

Over 109 historic and contemporary drillholes

• Dominantly shallow drilling

Dart completed:

• 1350m RAB drilling in 2020 (42 holes)

• 951m RC drilling in 2021 (6 holes)

• 997m Diamond drilling completed (3 holes; 2022)

• Deepest hole on the project 429m (Feb 2022)

• 16km IP & MT geophysics (6 lines; 2021)

Recent geophysical survey shows large anomalies at 200-400m below surface

• None of the geophysical anomalies identified have ever been drilled - until now

• First phase drilling of geophysical targets completed

• Further 3040m Diamond drilling planned (10 holes)

==> picture [397 x 381] intentionally omitted <==

• Location

• Part of 6.9Moz[1] Rutherglen-Beechworth-Harrietville gold district

• Primary + Alluvial production

• Buckland shows extensive shallow primary workings (>100) but low primary production

• Scale

• 17.5km strike identified from ~7,500 surface samples

• Multiple parallel structures identified

• Thick mineralisation intersected >180m below surface

• Mineralisation extends to over 10m width at surface and down hole

• Style

• Shear hosted, orogenic gold system

• Strong association of gold with arsenic

• Strong similarities with Bendigo and Fosterville style gold mineralisation

• Multiple mineralization styles evident

  • Surface outcropping with vein-hosting high grade gold

  • Broad zones of disseminated sulphide hosted low and mid-grade gold in altered wall rock

Rushworth Gold Project

• The Rushworth Goldfield is located in Central Victoria, 45km northeast of the Fosterville Gold Mine

• Dart’s tenure is surrounded by major explorers such as Newmont Mining, Chalice Gold Mines and Nagambie Resources

• Dart owns 100% of licences covering the Rushworth Goldfield

• The mineralisation at Rushworth is orogenic epizonal quartz-vein style that is interpreted to be genetically similar to the Fosterville high-grade gold style

• Multiple structures evident with three primary quartz vein orientations

• Two main parallel lines of strike, both over 7km long

• Limited historic mining and drilling have intersected mineralised veins to 200m depth

• Very high grade-gold historically mined

• Very few historic mines developed below the water table (~50m depth)

==> picture [274 x 230] intentionally omitted <==

• Dart recently completed a ~1300m RC drill program designed to intersect multiple mineralised vein sets and provide a bulk sample to accurately assess gold content at the prospect.

• Results included:

• 12m @ 1.26 g/t Au; inc . 2m @ 3.49 g/t in RARC06 from surface

• 8m @ 1.02 g/t Au; inc . 3m @ 2.26 g/t in RBRC07 from surface
