In the interview, Mr Langworthy highlights the significant exploration opportunity at the Company’s flagship Gidgee Gold Project in Western Australia, including:

• Why exploration of old gold mines in Western Australia has become a popular and successful strategy because of the significant untapped gold endowment of many Archaean gold systems across the State;

• The key geological attributes of the Gidgee Project which attracted Mr Langworthy to the project in the first place, given his 30-plus year experience as a geologist;

• The strategic imperative to explore historical gold fields in a significantly improved gold price environment;

• Upcoming milestones for Gateway this year including the potential for interim Resource statements on its Montague and Whistler gold deposits, as well as planned drilling to expand the scale of both deposits and along the broader contact between the Montague Granodiorite and the mafic host rock;

• How Gateway is aiming to de-risk its project from an investor perspective and establish the fundamentals to underpin a long-term mid-tier gold business.
