REGIONAL GEOLOGICAL SETTING

• The Lachlan Fold Belt and associated Macquarie Arc rocks host a significant proportion of mineralisation in Eastern Australia

• Geology is the fundamental precursor for any mineral exploration

• The geological setting of Northeast Victoria is diverse, dynamic, and under-explored

• Dart Mining has a strong foothold in the central Lachlan Fold Belt, with several mineral systems identified already

SUMMARY

• Exceptional and commanding tenement position in a highly prospective under-explored region

• Renewable energy transition is underpinning demand for entire metals complex and many of these critical minerals are represented within Dart’s exploration portfolio

• Positive long-term price fundamentals including covid-19 related supply constraints causing severe restrictions on metals production and production development = perfect storm

• Geolocation of projects increasingly important to avoid unreliable supply dependencies

• DTM is cheap vs. peers and has higher levels of prospectivity

• Well funded with very supportive long term shareholders

DTM is a low cost explorer that is self-reliant with a systematic and focussed exploration approach
