Exploration Targets Cautionary Statement

• This presentation may comment on and discuss Gateway Mining Limited’s exploration in terms of target size and type. The information relating to Exploration Targets should not be misunderstood or misconstrued as an estimate of Mineral Resources or Ore Reserves. The potential quantity and quality of material discussed as Exploration Targets is conceptual in nature since there has been insufficient work completed to define them as Mineral Resources or Ore Reserves. It is uncertain if further exploration work will result in the determination of a Mineral Resource or Ore Reserve.

• Any Exploration Targets referred to in this presentation are not Mineral Resources. The Potential quantity and grade of the Exploration targets are conceptual in nature and there has been insufficient exploration to determine a Mineral Resource. There is no certainty that additional exploration work will result in the estimation and reporting of Mineral Resources.

Project Build – Consolidation of 1,000km[2]

==> picture [307 x 445] intentionally omitted <==

MAJOR EXPANSION OF GIDGEE GOLD PROJECT

Gateway takes control of under-explored, highly prospective 30km structural corridor to complement existing Project, expanding land-holding to over 1,000km2 via strategic farm-in deal

• Covers an area of approximately 400km2 spanning the western side of the highly prospective Gum Creek Greenstone Belt

• Host to a ~30km long major gold-bearing structural corridor (termed the “Woodley Domain”) has been defined through the project.

• Third major identified gold trend within the belt after:

• Eastern Montague Domain: +1Moz endowment

• Central Gidgee Domain: +2Moz endowment .

• Previous exploration highlights significant gold anomalism, which have only been followed up by rudimentary drilling:

• 40 metres @ 3.0g/t Au from surface

• 20 metres @ 2.5g/t Au from surface

• 24 metres @ 3.3g/t from surface

• 11 metres @ 4.5g/t Au from 58m

• 20 metres @ 1.3g/t Au from surface

• 22 metres @ 2.3g/t Au from 61m
