■ Maiden drilling programs complete with significant success:

■ Whistler ■ Montague

■ Caledonian part of a bigger, emerging gold system that requires additional drilling

■ 1[st] Stage regional aircore assessment complete

■ Assays pending

■ Next stage RC, diamond and aircore drilling program in planning and approvals phase.

■ Evaluation of eastern contact

■ Strategy is to:

■ Rapidly define the size and quality of the mineralised system

■ Commence resource evaluation and definition

■ 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 recent 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

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