• Resource expansion at Whistler and Montague

• Achilles Exploration Target

• Systematic testing of the Granodiorite margin

• 18 strike kilometres of contact margin zone to be tested

• Major litho-structural corridors

■ Investment in quality integrated datasets

Exploration Upside – Achilles Exploration Target

■ Achilles Exploration Target (see ASX announcement 3/10/19)

• Tonnage Range 1.2 Mt to 3.4 Mt

• Grade Range 2.3g/t to 3.4g/t Au

• Contained Gold Range 88,000oz to 370,000oz

• Depth Range 0m to 200m

• Based on drilling and projection of these results at depth

• Multiple gold lodes over 1.5km – single gold system??

• Combination of discrete high-grade shear zones and stockwork zones on margin of the granodiorite

• Drilling program targeting resource conversion and new discovery.

Cautionary Statement

The Exploration Targets reported within this announcement 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.

14

Exploration Upside – Eastern Margin

■ Located on the ~10km long highly prospective Eastern Margin

■ Immediate along strike of the Howards Deposit (200koz – owned by HRN)

■ 1.8km long coincident gold-silver anomaly

• Requires 1[st] pass aircore drill testing

Exploration Upside – Regional Opportunities

■ Detailed gravity survey (see ASX announcement 20/9/19)

■ Unlock regional potential

• Integration with other high-quality datasets

• Unlock key structural and lithological trends

• Maps out the prospective contact of the Montague Granodiorite allowing effective planning of drilling programs.

• 3D Modeling of the contact provides a key understanding of the contact geometry at depth.

• ■ Facilitates targeting of intrusions similar to the Montague Granodiorite that have not previously been identified in the region.

• Target gold deposit styles based on Kanowna Belle and Wallaby analogues.

• Provide critical information to develop exploration concepts for follow-up work at the Flametree VHMS copper-zinc-gold system

16

Regional Setting

■ MDI / AME

• 1 March: MDI Offer to acquire AME through $9.4m merger

• Expanded resource base to support refurbishment of 600ktpa Sandstone Gold Plant located 80km south of Gidgee

• MDI Resource base: ~3.0mt @ 1.32g/t Au for 125,000oz Au

• AME Resource base: ~5.4mt @ 1.7g/t Au for 290,000oz Au

■ HRN - Care and Maintenance

• Upgraded resource base (840,000koz free-milling gold)

• Located 20km to north of Gidgee Gold Project

■ Active producers and developers

• Ramelius (RMS) Mt Magnet

• Blackham (BLK) Wiluna

• Westgold (WGX) Meekatharra / Cue

• ■ Goldfields Ltd Agnew

17

• Reporting of Maiden Resource of 240,000oz represents an important first step in the Company’s strategy to develop a new large-scale gold project.

• Sets a strong initial foundation from which to unlock the broader potential of what is believed to be a highly prospective emerging gold system.

• Team, funding and commitment in place

• Major drilling program underway

• Program of work over next 6 months:

■ RC drilling: October - November ■ Aircore drilling: November – December

■ Follow-up drilling as required

■ Resource Expansion drilling at Whistler and Montague Gold Deposits

■ Targeting resource conversion and new discovery at the Achilles Exploration Target

■ Systematic drill testing of granodiorite contact (RC and Aircore)
