Wetar Resource Expansion - - Partolang Exploration work has been very successful in finding and developing additional copper and pyrite resources: A significant new resource has been defined at Partolang indicating a viable copper resource close to existing operations Drilling after the cut-off date for the resource update has intercepted high grade mineralisation that is expected to further expand resources Target 3 year mine life extension with additional inferred resource likely to be converted Diagnostic leach tests show copper >80% soluble, superior to Lerokis Confirms success of exploration model 2019 Geophysical Survey 5,146,000 mN MERDEKA COPPER GOLD Wetar Copper Project Prospective Locations 200.000 m 202.000 mE 204,000 mE NEAR MINE PROSPECTS, ANOMALIES WITH REGIONAL ALTERATION & DRILLING 206,000 m 208 000 mE 0.5 Lurang kilometres Lerokis Pit starts Q2 2019 Kali Kuning Pit 2017 - 2019 Partolang - Resource Definition Z8 Z4 Kelapa Tiga Z2 KB1 3KT Plant KK1 li Kuning KK3 25KT Plant Partolang PIT " Barumanu J27/4 KK2 LEGEND Coastline River Lerokis KK4 200.000. 202.000 E 204.000 mE 200.000 m Resources Kayulepa Road Production-Operation/ Exploration IUP Massive sulphide boundary Drillhole Alteration Clay-Chlorite Pervasive clay-silica Silica, Vuggy Silica Barite zone 206.300 E 3,14,000 N ■ Resources at Wetar are Volcanogenic Massive Sulfide (VMS) deposits Tonnes Grade Partolang (Mt) (Cu %) Contained Metal (Cu t) - The deposits generally appear in clusters and it is reasonably likely that more resources will be defined over time Indicated 8.6 1.2 101,000 Inferred 3.5 1.0 35,000 Total 12.1 1.1 136,000 ☐ A geophysical survey was completed during 2019 with approximately 20 targets identified within the mining lease.
