■ Large-scale gold system in a well-endowed gold region

■ Known shallow oxide mineralization:

• 150,000oz mined from shallow pits in the 1980s but no deep drilling

==> picture [115 x 107] intentionally omitted <==

■ Virtually untested by modern exploration techniques or technology:

■ Previous owners were successful despite barely scratching the surface

■ Targeting high-grade gold in major shear systems on the margin of the granitoid intrusion

Gidgee Gold Project

• Associated granite-hosted sheeted veins and stockwork mineralization

• Volcanic Hosted Massive Sulphide (VHMS) deposit potential

Gateway’s strategy is in line with the highly successful approach implemented at many well-known but under-explored WA gold projects

• Gidgee Project comprises a core position over the highly endowed Archaean Greenstone Belt (~2Moz)

• Consolidated ground-holding of 600km[2]

• Located immediately adjacent to Gum Creek Gold Project, being developed by Horizon Gold (ASX: HRN):

• 17.3Mt at 2.25g/t Au for 1.25Moz[1]

• Well-developed infrastructure throughout the region

• Targeting large-scale gold systems analogous to:

• Granny Smith (+2Moz: Gold Fields)

• Tarmoola-King of the Hills (2.3Moz: RED 5)

• Minimal systematic exploration historically

Gateway is expanding an extensive, quality asset base in WA’s premier mineral belts, underpinned by an advanced high quality gold project at Gidgee

• A new growth opportunity in the WA gold sector following consolidation of the Gidgee gold tenure

• A Tier-1 address for gold exploration, development and mining

• Proven gold endowment as evidenced by historical mining and drilling

• Virtually no modern, systematic exploration – and no drilling at depth

• Prospective geology for large-scale gold system with multi-million ounce potential

• Initial metallurgical tests show the ore is free-milling

• Potential for significant VHMS copper discoveries in addition to gold

• Aggressive drilling campaigns commencing in March 2018 targeting extensions of known mineralisation

Gateway is aiming to systematically build a gold resource base at Gidgee capable of sustaining a mid-tier scale gold business
