COMPLETION OF PURCHASE OF OMNI PROJECTS

On 1 March 2018, Gateway Mining Limited ( Company ) announced it had entered into a Sale and Purchase Agreement ( Agreement ) whereby it would acquire all of the issued capital in Omni Projects Pty Ltd ( Omni Projects ) from its sole shareholder Omni GeoX Pty Ltd ( Omni GeoX ) ( Acquisition ). Also refer to the Company’s announcement of 22 December 2018 for further details.

The Company is pleased to advise that the purchase of Omni Projects completed today following satisfaction of all conditions precedent under the Agreement.

As previously announced, the acquisition of Omni Projects has allowed the Company to consolidate and expand its position at the Gidgee Gold Project in Western Australia, as well as creating opportunities for exposure to a series of exploration projects adjacent to major gold deposits across Western Australia. As a result of the successful completion of the Acquisition, the Gidgee Project will now comprise a consolidated area of 600km[2] covering the southern extension of the Archaean aged Gum Creek Greenstone Belt.

The Company’s new exploration strategy will be driven by experienced well credentialed geologist and newly appointed Managing Director, Mr Peter Langworthy.

Yours faithfully

Gary Franklin Company Secretary GATEWAY MINING LIMITED
